     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with a display generation component. The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. As used herein, “displaying” content includes causing to display the content (e.g., video data rendered or decoded by display controller  156 ) by transmitting, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content. 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards.

     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 .

     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more depth camera sensors  175 .  FIG.  1 A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 . Depth camera sensor  175  receives data from the environment to create a three dimensional model of an object (e.g., a face) within a scene from a viewpoint (e.g., a depth camera sensor). In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG.  1 A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG.  1 A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  is, optionally, coupled to an input controller  160  in I/O subsystem  106 . Accelerometer  168  optionally performs as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer and a GPS (or GLONASS or other global navigation system) receiver for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) stores device/global internal state  157 , as shown in  FIGS.  1 A and  3   . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input).

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG.  1 A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 ( 187 - 1 ), event 2 ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally, executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG.  1 A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG.  3    is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG.  4 A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG.  5 A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS.  1 A- 4 B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG.  5 B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS.  1 A,  1 B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including processes  700 ,  800 ,  1000 , and  1200  ( FIGS.  7 ,  8 ,  10 ,  12 A, and  12 B ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG.  5 B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS.  1 A,  3 , and  5 A- 5 B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or touch screen  112  in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally, based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
       FIG.  5 C  illustrates detecting a plurality of contacts  552 A- 552 E on touch-sensitive display screen  504  with a plurality of intensity sensors  524 A- 524 D.  FIG.  5 C  additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors  524 A- 524 D relative to units of intensity. In this example, the intensity measurements of intensity sensors  524 A and  524 D are each 9 units of intensity, and the intensity measurements of intensity sensors  524 B and  524 C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors  524 A- 524 D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity.  FIG.  5 D  illustrates assigning the aggregate intensity to contacts  552 A- 552 E based on their distance from the center of force  554 . In this example, each of contacts  552 A,  552 B, and  552 E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts  552 C and  552 D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to  FIGS.  5 C- 5 D  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in  FIGS.  5 C- 5 D  to aid the reader. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
       FIGS.  5 E- 5 H  illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact  562  from an intensity below a light press intensity threshold (e.g., “IT L ”) in  FIG.  5 E , to an intensity above a deep press intensity threshold (e.g., “IT D ”) in  FIG.  5 H . The gesture performed with contact  562  is detected on touch-sensitive surface  560  while cursor  576  is displayed over application icon  572 B corresponding to App 2, on a displayed user interface  570  that includes application icons  572 A- 572 D displayed in predefined region  574 . In some embodiments, the gesture is detected on touch-sensitive display  504 . The intensity sensors detect the intensity of contacts on touch-sensitive surface  560 . The device determines that the intensity of contact  562  peaked above the deep press intensity threshold (e.g., “IT D ”). Contact  562  is maintained on touch-sensitive surface  560 . In response to the detection of the gesture, and in accordance with contact  562  having an intensity that goes above the deep press intensity threshold (e.g., “IT D ”) during the gesture, reduced-scale representations  578 A- 578 C (e.g., thumbnails) of recently opened documents for App 2 are displayed, as shown in  FIGS.  5 F- 5 H . In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact  562  is not part of a displayed user interface, but is included in  FIGS.  5 E- 5 H  to aid the reader. 
     In some embodiments, the display of representations  578 A- 578 C includes an animation. For example, representation  578 A is initially displayed in proximity of application icon  572 B, as shown in  FIG.  5 F . As the animation proceeds, representation  578 A moves upward and representation  578 B is displayed in proximity of application icon  572 B, as shown in FIG. Then, representations  578 A moves upward,  578 B moves upward toward representation  578 A, and representation  578 C is displayed in proximity of application icon  572 B, as shown in  FIG.  5 H . Representations  578 A- 578 C form an array above icon  572 B. In some embodiments, the animation progresses in accordance with an intensity of contact  562 , as shown in  FIGS.  5 F- 5 G , where the representations  578 A- 578 C appear and move upwards as the intensity of contact  562  increases toward the deep press intensity threshold (e.g., “IT D ”). In some embodiments, the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to  FIGS.  5 E- 5 H  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
       FIG.  5 I  illustrates exemplary electronic device  580 . Device  580  includes body  580 A. In some embodiments, device  580  can include some or all of the features described with respect to devices  100 ,  300 , and  500  (e.g.,  FIGS.  1 A- 5 B ). In some embodiments, device  580  has one or more speakers  580 B (concealed in body  580 A), one or more microphones  580 C, one or more touch-sensitive surfaces  580 D, and one or more displays  580 E. Alternatively, or in addition to a display and touch-sensitive surface  580 D, the device has a touch-sensitive display (also referred to as a touchscreen). As with devices  100 ,  300 , and  500 , in some embodiments, touch-sensitive surface  580 D (or the touch screen) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch-sensitive surface  580 D (or the touchscreen) can provide output data that represents the intensity of touches. The user interface of device  580  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  580 . In some embodiments, the one or more displays  580 E are one or more light-emitting diodes (LEDs). For example, a display can be a single LED, an LED cluster (e.g., a red, a green, and a blue LED), a plurality of discrete LEDs, a plurality of discrete LED clusters, or other arrangement of one or more LEDs. For example, the display  580 E can be an array of nine discrete LED clusters arranged in a circular shape (e.g., a ring). In some examples, the one or more displays are comprised of one or more of another type of light-emitting elements. 
       FIG.  5 J  depicts exemplary personal electronic device  580 . In some embodiments, device  580  can include some or all of the components described with respect to  FIGS.  1 A,  1 B,  3   , and  5 A- 5 B. Device  580  has bus  592  that operatively couples I/O section  594  with one or more computer processors  596  and memory  598 . I/O section  594  can be connected to display  582 , which can have touch-sensitive component  584  and, optionally, intensity sensor  585  (e.g., contact intensity sensor). In some embodiments, touch-sensitive component  584  is a separate component than display  582 . In addition, I/O section  594  can be connected with communication unit  590  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  580  can include input mechanisms  588 . Input mechanism  588  is, optionally, a button, in some examples. Input mechanism  588  is, optionally, a microphone, in some examples. Input mechanism  588  is, optionally, a plurality of microphones (e.g., a microphone array). 
     Electronic device  580  includes speaker  586  for outputting audio. Device  580  can include audio circuitry (e.g., in I/O section  594 ) that receives audio data, converts the audio data to an electrical signal, and transmits the electrical signal to speaker  586 . Speaker  586  converts the electrical signal to human-audible sound waves. The audio circuitry (e.g., in I/O section  594 ) also receives electrical signals converted by a microphone (e.g., input mechanism  588 ) from sound waves. The audio circuitry (e.g., in I/O section  594 ) converts the electrical signal to audio data. Audio data is, optionally, retrieved from and/or transmitted to memory  598  and/or RF circuitry (e.g., in communication unit  590 ) by I/O section  594 . 
     Memory  598  of personal electronic device  580  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  596 , for example, can cause the computer processors to perform the techniques described below, including processes  700 ,  800 ,  1000 , and  1200  ( FIGS.  7 ,  8 ,  10 , and  12   ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  580  is not limited to the components and configuration of  FIG.  5 J , but can include other or additional components in multiple configurations. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , device  500 , or device  580 . 
       FIGS.  6 A- 6 X  illustrate exemplary user interfaces for managing media playback devices, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  7  and  8   . 
       FIGS.  6 A- 6 X  illustrate various embodiments depicting a position, location, and/or movement of device  600  relative to device  605 , and responses at devices  600  and  605  based on the relative position/location/movement and various states of devices  600  and  605 . The relative position/location/movement of the devices is depicted in diagram  610 , which shows outer threshold distance  610 - 1  (also referred to herein as outer threshold  610 - 1 ) from device  605  and inner threshold distance  610 - 2  (also referred to herein as inner threshold  610 - 2 ) from device  605 . In order to depict the location of device  600  relative to outer threshold  610 - 1  and inner threshold  610 - 2 , the location of device  600  is represented by edge portion  600 - 1 , which generally corresponds to the top corner(s) of device  600 . In some embodiments, device  600  includes one or more features of device  100 , device  300 , and/or device  500 , and device  605  includes one or more features of device  580 . For example, device  600  includes display  601 , and device  605  includes touch-sensitive surface  605 - 1  (similar to touch-sensitive surface  580 D), one or more displays  605 - 2  (similar to display  580 E), and one or more speakers  605 - 3  (similar to speakers  580 B concealed in body  580 A). In the embodiments illustrated in  FIGS.  6 A- 6 X , display  605 - 2  is generally distinguished from touch-sensitive surface  605 - 1  by the depiction of light (e.g., light  607 ). However, because the display may not be activated in all figures or, when activated, the light can vary in displayed size (as well as other characteristics such as brightness, intensity, color, pattern, movement, etc.), reference number  605 - 2  should be understood to refer generally to the display component of device  605 . In some embodiments, the different colors of light  607  are represented by different hatch patterns, and the brightness of light  607  is represented by the shade of light  607  depicted in the figures. For example, darker shades of light  607  can represent brighter display of light, and lighter shades of light  607  can represent dimmer display of light. 
     In some embodiments, the figures depict indicators  602 A,  602 B,  604 A,  604 B, and  634 B to indicate different audio outputs at each of the devices. For example, indicator  602 A indicates a first song is being played (output) at device  600 , and indicator  602 B indicates the first song is being played at device  605 . Similarly, indicator  604 A indicates a second song, different from the first song, is being played at device  600 , and indicator  604 B indicates the second song is being played at device  605 . Indicator  634 B indicates communication audio is being output at device  605 . The indicators are displayed having different sizes to represent the volume at which the respective audio is being output. In the embodiments depicted in  FIGS.  6 A- 6 X , the volume ranges from 1 to 5, with 1 being the lowest output volume, and 5 being the highest output volume. In some embodiments, a volume of 5 represents the current volume setting of the respective device, and volumes 1-4 represent volumes less than the current volume setting. The volumes are also indicated by a numeric value appended to the reference numbers in the figures. For example, reference number  602 A- 5  indicates the first song is being played at device  600  at volume 5 (e.g., full volume), whereas reference number  602 A- 1  indicates the first song is being played at device  600  at volume 1. Similar nomenclature is used in other instances where appropriate. When no indicator (e.g.,  602 A,  602 B,  604 A,  604 B) is shown next to device  600  or device  605  in  FIGS.  6 A- 6 X , no audio is being output at the respective device. 
       FIGS.  6 A- 6 C  depict an embodiment in which device  600  is playing audio while device  605  is not, and device  600  displays an interface for manually transferring audio playback from device  600  to device  605  (e.g., without automatically transferring the audio for playback at device  605 ) in response to entering outer threshold  610 - 1  and detecting touch inputs on display  601 . In the embodiments discussed below, the audio at devices  600  and  605  is music. However, the audio can be other types of audio such as, for example, communication audio (e.g., audio from a phone call, a video communication session, a recording, etc.) or audio from other types of media playback (e.g., audio from a video game, movie). 
     In  FIG.  6 A , diagram  610  indicates that device  600  is positioned facing device  605  (device  600  is pointed toward device  605 ) and located outside outer threshold  610 - 1 . Device  600  is currently playing the first song (e.g., via one or more speakers of device  600 ) at full volume, as indicated by indicator  602 A- 5 , and is displaying home interface  603  on display  601 . Device  605  is currently not outputting any audio or displaying any lights. 
     In  FIG.  6 B , diagram  610  indicates that device  600  has moved toward device  605 , and is now positioned at outer threshold  610 - 1 . In response to detecting device  600  at outer threshold  610 - 1 , device  600  and device  605  begin to generate feedback to indicate that the song playing at device  600  can be transferred (e.g., handed off) for playback at device  605 . 
     Device  600  provides tactile feedback by generating a slight tactile output  606 , and generates visual feedback by displaying pill interface object  615  and beginning to blur  603 - 1  home interface  603  (the slight blurring is represented by large diamond hatching noted with reference  603 - 1 ). Device  600  also generates an audio feedback by reducing the volume of the first song, as depicted by indicator  602 A- 4 . Pill interface object  615  (also referred to herein as pill  615 ) includes text  615 - 1  that identifies device  605  (identified in this example as “Kitchen Speaker”) and provides instructions to a user of device  600  to move device  600  closer to device  605  or to tap pill  615  to display controls for device  605 . Pill  615  also includes representation  615 - 2  of device  605  and representation  615 - 3  of the first song (e.g., album art) that is being played at device  600 , which is the song that, in this example, is capable of being transferred to device  605 . 
     Device  605  generates visual feedback by displaying light  607  (e.g., via display  605 - 2 ) and generates audio feedback by beginning to play the first song as depicted by indicator  602 B- 1 . The output of the first song at device  605  is at a low volume and is in sync with playback of the first song at device  600 , so that both device  600  and device  605  are playing the first song simultaneously, but at different volumes. In some embodiments, the audio feedback at device  605  is generated such that the first song, as outputted by device  605 , has one or more audio characteristics (e.g., pitch, tone, frequency range) that approximate audio output by the audio hardware output of device  600 . For example, the first song can be played at device  605  with audio characteristics that sound tinnier (e.g., having less bass, having a higher pitched frequency range) than the normal audio characteristics with which device  605  would playback the first song after transfer is complete (e.g., as described with respect to  FIG.  6 H ) that mimics the quality of the audio generated at device  600 . As discussed in greater detail below, the audio at device  605  blossoms to a fuller, richer sound (e.g., having more base, having a wider range of frequencies) when the first song is transferred for playback at device  605 . 
     The feedback at devices  600  and  605  provides a cue to the user of device  600  that the first song can be transferred for playback at device  605 , and provides instruction to the user to initiate the transfer of the song to device  605  by moving device  600  toward device  605  or by providing further input (e.g., touch input) at device  600 . Although the first song is being output at device  605  as part of the audio feedback, playback of the first song has not transferred to device  605 . In some embodiments, this is because device  600  still maintains control (e.g., primary control) of playback of the song. For example, device  600  controls whether the first song is playing, paused, stopped, or whether a different song is selected for playback. Additionally, if device  600  moves outside of outer threshold  610 - 1 , the first song stops being played at device  605  and continues playing at full volume at device  600 . In some embodiments, transfer is not complete until device  605  is playing back audio (e.g., the first song) without reference to the relative distance between device  600  and device  605 . In some embodiments, transfer is not complete until device  600  is no longer outputting the audio that was transferred (e.g., no longer outputting audio feedback that includes playing back the audio (e.g., the first song)). 
     In some embodiments, device  605  initially pulses light  607  to a bright state with a large size when device  600  reaches outer threshold  610 - 1 , and then slightly dims and shrinks the size of the light to the state depicted in  FIG.  6 B . In some embodiments, device  605  displays light  607  having a particular color, depending on the type of audio that is being prepared for transfer to device  605 . For example, if the audio is communication audio, the light is green, or if the audio is music, the light is white. In some embodiments, when the audio begins to play at device  605 , light  607  changes to a color that corresponds to the first song. For example, if the album art (e.g., representation  615 - 3 ) includes purple coloring, light  607  turns purple to correspond to the album art of the first song. In some embodiments, this transition to the colored light occurs as device  600  moves towards device  605 , as discussed in greater detail below. In some embodiments, the different colors of light  607  are represented by different hatch patterns, and the brightness of light  607  is represented by the shade of light  607  depicted in the figures. For example, darker shades of light  607  can represent brighter display of light, and lighter shades of light  607  can represent dimmer display of light. 
     In  FIG.  6 B , device  600  detects input  608  (e.g., a tap input) on pill  615  and, in response, expands pill  615  to display controls interface  612 , as shown in  FIG.  6 C . 
     In  FIG.  6 C , device  600  is still located at outer threshold  610 - 1 . Device  600  continues to play the first song at a volume of 4, as depicted by indicator  602 A- 4 , and device  605  continues to generate the audio feedback by playing the first song at a volume of 1, as depicted by indicator  602 B- 1 , while continuing to display light  607 . The first song is not yet transferred for playback at device  605 , as discussed in greater detail below. Instead, playback of the first song continues to be performed at device  600 , and controls interface  612  is displayed to provide the user of device  600  with the option to manually transfer playback of the first song from device  600  to device  605 , or to perform a number of other options at device  605 . 
     Controls interface  612  is a user interface that provides controls that can be used to control various operations using device  605 . For example, controls interface  612  includes media playback controls  612 - 1 , which can be selected to control the playback of audio at device  605 . As shown in  FIG.  6 C , device  605  is currently not playing audio (other than the audio feedback represented by indicator  602 B- 1 ), and media playback controls  612 - 1  include controls to play or pause audio, controls to seek tracks for playback at device  605 , and controls for adjusting a volume setting of device  605 . Controls interface  612  also includes status  612 - 2  indicating that device  605  is not playing audio, and representations  612 - 3  of recommended songs that can be selected for playback at device  605 . Controls interface  612  also includes message controls  612 - 4 , for controlling messaging functions (e.g., composing, sending, and/or reading messages) using device  605 . 
     Controls interface  612  also includes transfer affordance  614 , which can be selected to immediately transfer playback of the first song from device  600  to device  605 . As shown in  FIG.  6 C , transfer affordance  614  includes a representation  614 - 1  of the song to be transferred to device  605 , text  614 - 2  identifying the song to be transferred, and text  614 - 3  indicating that the song is to be transferred from device  600 . In some embodiments, device  600  displays controls interface  612  without transfer affordance  614  when neither device  600  nor device  605  are playing audio. 
       FIGS.  6 D- 6 I  depict an embodiment similar to that shown in  FIGS.  6 A- 6 C . However, instead of tapping pill  615  to display controls interface  612 ,  FIGS.  6 D- 6 I  illustrate controls interface  612  automatically being displayed, and the first song automatically being transferred for playback at device  605 , when device  600  reaches inner threshold  610 - 2 .  FIGS.  6 D- 6 I  also further demonstrate the dynamic feedback at devices  600  and  605  in response to moving device  600  toward and away from device  605 . 
       FIG.  6 D  is similar to  FIG.  6 B , where device  600  is shown at outer threshold  610 - 1 , the visual, tactile, and audio feedback discussed above is generated at device  600  (including the display of pill  615 ), and the visual and audio feedback discussed above is generated at device  605 . 
     In  FIG.  6 E , device  600  moves closer to device  605 , as depicted in diagram  610 , without reaching inner threshold  610 - 2 . In response to the movement of device  600  toward device  605 , device  600  and device  605  vary their respective feedback to encourage continued movement of device  600  toward device  605  to complete the transfer of the first song from playback at device  600  to playback at device  605 . 
     Specifically, device  600  varies the tactile feedback by generating stronger tactile output  613 . In some embodiments, the tactile feedback varies based on the distance between device  600  and device  605 . For example, as device  600  gets closer to device  605 , the tactile outputs get stronger, and as device  600  moves away from device  605 , the tactile outputs get weaker. In some embodiments, the tactile feedback varies based on the velocity and/or direction of movement of device  600  toward device  605 . For example, if device  600  moves toward or away from device  605  slowly, the tactile feedback can include a series of disbursed, and optionally slight, tactile outputs as device  600  moves toward or away from device  605 . Conversely, if device  600  moves toward or away from device  605  quickly, the tactile feedback can include a series of rapid, and optionally stronger, tactile outputs as device  600  moves toward or away from device  605 . In some embodiments, as device  600  accelerates toward device  605 , the tactile feedback can include a series of tactile outputs that increase in frequency and, optionally, strength as device  600  moves toward device  605 . In some embodiments, the tactile output has characteristics that mimic the first song. For example, the tactile output has a pattern and, optionally, different magnitudes that imitate the beat of the first song. 
     Device  600  varies the audio feedback by decreasing the volume of the first song as depicted by indicator  602 A- 3 . Device  600  varies the visual feedback by increasing the blur  603 - 2  of home interface  603  (the increased blur is represented by medium diamond hatching noted with reference  603 - 2 ) and increasing the size of pill  615 , including increasing the sizes of text  615 - 1 , representation  615 - 2 , and representation  615 - 3 . Additionally, device  600  displays representation  615 - 3  positioned closer to representation  615 - 2 . Thus, as device  600  moves towards  605 , the tactile output increases, the audio of the first song decreases, home interface  603  gets blurrier, pill  615  increases in size, and the album art for the first song moves toward the representation of device  605 . The foregoing tactile, audio, and visual feedback actions individually, and collectively, provide feedback to the user indicating that playback of the first song will transfer from device  600 , thereby encouraging the user to continue moving device  600  toward device  605  in order to transfer playback of the first song from device  600  to device  605 . 
     Device  605  varies the audio feedback by increasing the volume of the first song as depicted by indicator  602 B- 2 , and varies the visual feedback by increasing the size and brightness of light  607 , and changing the color of light  607  to purple, as indicated by the hatch pattern of light  607 . In some embodiments, as part of the feedback, device  605  animates light  607  while outputting the first song. For example, device  605  causes light  607  to change colors, flicker with the beat of the first song, and/or have an appearance of moving on display  605 - 2 . The foregoing visual and audio feedback actions individually, and collectively, provide feedback to the user that the first audio will be played at device  605 , thereby encouraging the user to continue moving device  600  toward device  605  in order to transfer playback of the first song to device  605 . 
     In  FIG.  6 F , device  600  has moved back away from, and is no longer facing, device  605 , while remaining between outer threshold  610 - 1  and inner threshold  610 - 2 . In response, device  600  and device  605  vary their respective feedback to indicate that device  600  is no longer moving in the direction to effect the transfer of the first song from playing at device  600  to playing at device  605 . For example, device  600  partially reverses the prior feedback changes by increasing the volume of the first song, as depicted by indicator  602 A- 4 , and decreasing the blur of home interface  603 , reducing the size of pill  615 , including text  615 - 1  and representations  615 - 2  and  615 - 3 , and moving representation  615 - 3  away from representation  615 - 2 . Because device  600  is slightly past outer threshold  610 - 1 , pill  615  is smaller than depicted in  FIG.  6 E , but larger than depicted in  FIG.  6 D  (when device  600  is at outer threshold  610 - 1 ). Accordingly, text  615 - 1  and representations  615 - 2  and  615 - 3  are slightly larger than depicted in  FIG.  6 D , and representation  615 - 3  is slightly closer to representation  615 - 2  than depicted in  FIG.  6 D . 
     In  FIG.  6 F , device  605  reverses the prior feedback changes by decreasing the volume of the first song, as depicted by indicator  602 B- 1 , and decreasing the size, brightness, and purple hue of light  607 . 
     In some embodiments, device  600  does not generate a tactile feedback depending on the context of device  600 . For example, as shown in  FIG.  6 F , device  600  does not generate a tactile output because device  600  is not facing device  605 . Device  600  may not generate a tactile output in other instances such as when device  600  is charging or stationary. 
     Referring now to  FIGS.  6 G- 6 I , device  600  is again facing device  605  and is now located at inner threshold  610 - 2 , as depicted in diagram  610 . As discussed in greater detail below, the feedback at device  600  and device  605  continues to vary (e.g., while device  600  is between outer threshold  610 - 1  and inner threshold  610 - 2 ) until device  600  reaches inner threshold  610 - 2 , at which point, device  600  transfers playback of the first song to device  605  and devices  600  and  605  stop varying their respective feedback. 
     As device  600  moves toward device  605 , device  600  generates visual feedback that includes increasing the blur  603 - 3  of home interface  603  (the increased blur is represented by small diamond hatching noted with reference  603 - 3 ), increasing the size of pill  615  (including text  615 - 1  and representations  615 - 2  and  615 - 3 ), and moving representation  615 - 3  toward representation  615 - 2 , as shown in  FIG.  6 G . When device  600  reaches inner threshold  610 - 2 , device  600  transfers playback of the first song to device  605  and displays pill  615  transitioning to controls interface  612 , as shown in  FIGS.  6 H and  6 I . 
     In  FIG.  6 H , device  600  displays controls interface in a transitory state (represented by reference number  612 ′) as it fully expands from pill  615  in  FIG.  6 G  to controls interface  612  in  FIG.  6 I . Controls interface  612 ′ includes playback controls  612 - 1 , status  612 - 2 , and album art  612 - 5  for the song playing at device  605 . In  FIGS.  6 H and  6 I , status  612 - 2  and album art  612 - 5  indicate that the first song “Track 1, Artist 1” is now being played at device  605 , and controls  612 - 1  include playback controls for controlling playback of the first song at device  605 . In some embodiments, device  600  also generates tactile output  616  as pill  615  expands, as shown in  FIGS.  6 G and  6 H . 
     In  FIG.  6 I , controls interface  612  is further expanded to include timer controls  612 - 6 , which can be selected to control the function of timers at device  605 . For example pause control  612 - 6   a  can be selected to pause a timer (e.g., “Laundry” timer) that is operating at device  605 , and stop control  612 - 6   b  can be selected to stop the timer. 
     Referring again to  FIG.  6 G , device  605  generates visual feedback by increasing the size, brightness, and purple hue of lights  607 , and generates audio feedback by increasing the volume of the first song, as depicted by indicator  602 B- 3 . In the embodiment depicted in  FIGS.  6 G- 6 H , device  605  pulses light  607  when the audio is transferred to device  605  for playback. In  FIG.  6 H , light  607  is shown pulsing to have increased brightness, size, and purple hue during the media transfer. The pulse of light  607  is depicted in  FIG.  6 H  (and similar figures) by outer portion  607 - 1  of light  607  and inner portion  607 - 2  of light  607 , which represent a temporary increase in the size and, optionally, brightness of light  607 . The increased size is depicted by the larger displayed region of light  607 . The increased brightness is depicted by the darker shading of inner portion  607 - 2 . Outer portion  607 - 1  has the same shade as light  607  in  FIG.  6 G , and inner portion  607 - 2  is depicted with a darker shade than outer portion  607 - 1 , indicating that the inner portion of light  607  is brighter than outer portion  607 - 1  (and light  607  in  FIG.  6 G ). In some embodiments, device  605  blinks light  607  in addition to, or in lieu of, the pulsing light  607 . In  FIG.  6 I , light  607  is shown after the pulse and having a normal play state while device  605  plays the first song. 
     As previously discussed, as device  600  moves toward device  605 , device  600  decreases the volume of the first song, and device  605  increases the volume of the first song. Upon reaching inner threshold  610 - 2 , device  600  transfers playback of the first song to device  605 . As part of this transfer, device  600  continues to decrease the volume of the first song, while device  605  continues to increase the volume of the first song, as depicted by indicator  602 A- 2  and indicator  602 B- 3 , respectively. Additionally, during this transfer, the audio at device  605  changes from the tinny sound to a full, rich audio sound. These changes in volume continue as device  600  transfers playback of the first song to device  605 , as shown in  FIGS.  6 G- 6 I . When playback of the first song is transferred to device  605 , as shown in  FIG.  6 I , device  600  is no longer playing the first song, and device  605  is playing the first song at full volume, as depicted by indicator  602 B- 5 . 
     As depicted in  FIGS.  6 J- 6 M , device  600  and device  605  no longer vary feedback based on movement of device  600  relative to device  605  after the audio has been transferred to device  605 . To re-enable the feedback, device  600  is moved beyond outer threshold  610 - 1 , as depicted in  FIG.  6 M . 
     In  FIG.  6 J , device  600  is moved closer to device  605 , as depicted in diagram  610 . Device  600  continues to display controls interface  612  without generating any feedback based on the movement of device  600 . Similarly, device  605  continues to play the first song without generating any feedback based on the movement of device  600 . In some embodiments, device  605  animates light  607  with the playback of the first song, but this animation of light  607  is not based on the movement of device  600 . 
     In  FIG.  6 K , device  600  is moved away from device  605 , as depicted in diagram  610 . Device is positioned between outer threshold  610 - 1  and inner threshold  610 - 2 . Device continues to display controls interface  612  without generating any feedback based on the movement of device  600 . Device  605  continues to play the first song without generating any feedback based on the movement of device  600 . 
     In  FIG.  6 L , device  600  is moved away from device  605 , as depicted in diagram  610 . Device  600  is positioned outside of outer threshold  610 - 1 . Device  600  continues to display controls interface  612  without generating any feedback based on the movement of device  600 . Device  605  continues to play the first song without generating any feedback based on the movement of device  600 . In some embodiments, when device  600  is moved outside a threshold distance of device  605  (e.g., inner threshold  610 - 2  or outer threshold  610 - 1 ), the audio stops playing at device  605 , and resumes playing at device  600 , depending on the type of audio. For example, in some embodiments, music continues to play at device  605 , but communication audio stops playing at device  605  and continues playing at device  600 . 
     In  FIG.  6 M , device  600  is moved toward device  605  and is now located at outer threshold  610 - 1 , as depicted in diagram  610 . In response to detecting device  600  re-entering outer threshold  610 - 1 , device  600  and device  605  begin to vary feedback based on the movement of device  600  relative to device  605  and based on the respective states of devices  600  and  605 . 
     For example, as illustrated in  FIG.  6 M , device  605  is currently playing the first song, and device  600  is not. When device  600  reaches outer threshold  610 - 1 , device  600  and device  605  begin to generate feedback to indicate to the user of device  600  that continued movement of device  600  toward device  605 , will cause the audio to transfer from device  605  to device  600 . Accordingly, device  600  generates audio feedback by playing the first song at a low volume, as depicted by indicator  602 A- 1 , and device  605  generates audio feedback by decreasing the volume of the first song, as depicted by indicator  602 B- 4 . Additionally, device  600  generates visual feedback by displaying transfer affordance  620 . Transfer affordance  620  is similar to transfer affordance  614 , and can be selected to immediately transfer playback of the first song from device  605  to device  600 . 
     As shown in  FIG.  6 M , transfer affordance includes a representation  620 - 1  of the song to be transferred to device  600 , text  620 - 2  identifying the song to be transferred, and text  620 - 3  indicating that the song is to be transferred to device  600 . In some embodiments, device  605  generates visual feedback by dimming, shrinking, and, optionally, reducing a purple hue of light  607 . In some embodiments, in response to an input on transfer affordance  620 , device  605  pulses light  607  and, after the audio is transferred to device  600 , fades light  607  to an “off” setting. 
       FIGS.  6 N- 6 W  depict an embodiment in which both device  600  and device  605  are simultaneously playing different songs. 
     In  FIG.  6 N , device  605  is playing the first song, as depicted by indicator  602 B- 5  and light  607 , and device  600  is beyond outer threshold  610  and playing a second song, as depicted by indicator  604 A- 5  and music interface  625 , which is an interface for controlling playback of music at device  600 . Device  600  detects input  624  (e.g., a swipe gesture) and, in response, dismisses music interface  625  to display home interface  603 . 
     In  FIG.  6 O , device moves to outer threshold  610 - 1 , as depicted by diagram  610 . In response, device  600  begins to blur  603 - 1  home interface  603  and displays pill  615  having a small size. Because device  605  is currently playing the first song, pill  615  includes text  615 - 4  indicating that the device  605  (“Kitchen Speaker”) is currently playing the first song. Pill  615  also includes representation  615 - 2  and representation  615 - 3 . Device  605  continues to play the first song, with no variation in feedback based on movement of device  600 . 
     In  FIG.  6 P , device  600  moves closer to device  605  (without crossing inner threshold  610 - 2 ) and, in response, increases the blur  603 - 2  of home interface  603 , increases the size of pill  615  (including representations  615 - 2  and  615 - 3 ), and moves representation  615 - 3  toward representation  615 - 2 . Device  600  continues to play the second song, as depicted by indicator  604 A- 5 . Device  605  continues to play the first song, as depicted by indicator  602 B- 5  and light  607 . 
     In  FIG.  6 Q , device  600  reaches inner threshold  610 - 2  and, in response, increases the blur  603 - 3  of home interface  603  and expands pill  615  to controls interface  612 , with the transitory state of controls interface  612 ′ shown in  FIG.  6 Q  and the fully expanded state shown in  FIG.  6 R . Controls interface  612 ′ includes playback controls  612 - 1  for device  605 , status  612 - 2  indicating that device  605  is playing the first song, and album art  612 - 5  representing the first song. Device  605  continues to play the first song, as depicted by indicator  602 B- 5  and light  607 . In some embodiments, device  600  or device  605  adds the first song being played at device  605  to a queue for playback at device  600 , in response to detecting device  600  at inner threshold  610 - 2 . 
     In  FIG.  6 R , device  600  displays controls interface  612  in its fully expanded state. Controls interface  612  includes playback controls  612 - 1 , status  612 - 2 , and alarm controls  612 - 7 . Alarm controls  612 - 7  are selectable controls for controlling the function of one or more alarms at device  605 . For example, new control  612 - 7   a  can be selected to start a new alarm at device  605 . Because device  600  and device  605  are playing different songs, controls interface  612  also includes transfer affordance  626 . Transfer affordance  626  is similar to transfer affordance  614  and can be selected to immediately transfer playback of the second song from device  600  to device  605 . As shown in  FIG.  6 R , transfer affordance  626  includes a representation  626 - 1  of the song to be transferred to device  605 , text  626 - 2  identifying the song to be transferred, and text  626 - 3  indicating that the song is to be transferred from device  600 . In response to an input on transfer affordance  626 , device  605  stops playing the first song, and begins playing the second song. 
     In  FIG.  6 R , device  600  detects input  628  on pause control option  612 - 1   a  and, in response, pauses the first song being played at device  605 , as shown in  FIG.  6 S . 
     In  FIG.  6 S , the first song is paused at device  605 . Accordingly, device  600  displays controls interface  612  with playback controls  612 - 1  having a play affordance  612 - 1   b , and device  605  changes light  607  to a dim, small, and white light to indicate the paused state. Device  600  detects input  630  on transfer affordance  626  and, in response, transfers playback of the second song from device  600  to device  605 , as depicted in  FIG.  6 T . 
     In  FIG.  6 T , device  600  depicts controls interface  612  updated to indicate that device  605  is now playing the second song. Accordingly, controls interface  612  no longer includes transfer affordance  626 , and status  612 - 2  and album art  612 - 5  have been updated to represent the second song, which is now playing at device  605 . Device  605  is now playing the second song, as depicted by indicator  604 B- 5 , and light  607  which, as shown in  FIG.  6 T , is pulsing to a bright, large, white state during the transfer, before shrinking and changing to a blue color that corresponds to the album art of the second song, as shown in  FIG.  6 U . 
     In  FIGS.  6 U and  6 V , device  600  detects input  632  (e.g., a touch-and-drag gesture) and, in response, dismisses controls interface  612 , shrinking it back to the pill state, as shown in  FIG.  6 W . Device  605  continues to play the second song, as depicted by indicator  604 B- 5  and light  607 . 
     In  FIG.  6 W , pill  615  is shown with information that corresponds to the second song, including a representation of the second music and text indicating device  605  is playing the second song (Track 2—Artist 2). 
     As mentioned above, device  605  can play different types of audio and display light  607  having different colors based on the audio.  FIG.  6 X  depicts an embodiment in which device  605  is outputting communication audio for a phone call, as depicted by indicator  634 B, and displaying light  607  having a green color to indicate that the type of audio playing at device  605  is communication audio. In the embodiment in  FIG.  6 X , the audio for the phone call was transferred from device  600  to device  605  in a manner similar to that discussed above with respect to the transfer of music. Device  600  and device  605  also vary feedback based on the distance of device  600  from device  605 , as discussed above. For example, in  FIG.  6 X  device  600  is at outer threshold  610 - 1  and displays pill  615  having information for the phone call, while phone interface  635  is slightly blurred. Pill  615  includes text  615 - 5  indicating that a phone call is being played at device  605  (“Kitchen Speaker”). Pill  615  also includes representation  615 - 2  of device  605 , and representation  615 - 6  of phone call audio. 
       FIG.  7    is a flow diagram illustrating a method for managing media playback devices using an electronic device in accordance with some embodiments. Method  700  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 ) that is in communication with a first external device (e.g.,  605 ). Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     In some embodiments, the electronic device (e.g.,  600 ) is a computer system (e.g., a smartphone, a smartwatch; a smart speaker; a media playback device (e.g., a digital media player)) that is in communication with a first external device (e.g.,  605 ) (e.g., a smart speaker; a media playback device (e.g., a digital media player); a smartphone; a smartwatch). The computer system is optionally in communication (e.g., wired communication, wireless communication) with a display generation component (e.g.,  601 ). The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. Thus, the computer system can transmit, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content (e.g., using a display device). 
     As described below, method  700  provides an intuitive way for managing media playback devices. The method reduces the cognitive burden on a user for managing media playback devices, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage media playback devices faster and more efficiently conserves power and increases the time between battery charges. 
     In method  700 , the computer system (e.g.,  600 ) detects ( 702 ) a change in distance between the computer system and the first external device (e.g.,  605 ). In some embodiments, the change in distance is detected based on a change in signal strength (e.g., wireless signal strength) exchanged between the system and the first external device. In some embodiments, the change in distance is detected via one or more sensors (e.g., infrared sensors; optical sensors). In some embodiments, the change in distance is detected via data transmitted to the system from a Wi-Fi positioning system, from GPS, and/or from the first external device. 
     In response ( 704 ) to detecting the change in distance, the computer system (e.g.,  600 ) performs steps  706 - 712  of method  700 . 
     In response to detecting the change in distance, in accordance with a determination that a current distance of the computer system (e.g.,  600 ) from the first external device (e.g.,  605 ) is less than a first threshold distance (e.g.,  610 - 1 ) (e.g., a predetermined threshold distance (e.g., 6 inches, 12 inches, 18 inches); an outer threshold distance from the first external device) but greater than a second threshold distance (e.g.,  610 - 2 ) (e.g., a predetermined threshold distance that is less than the first threshold distance (e.g., 4 inches, 8 inches, 12 inches); an inner threshold distance from the first external device), the computer system generates ( 706 ) (e.g., outputs; initiates; initiates a process to generate) feedback (e.g., at the computer system and/or at the first external device) (in some embodiments, without performing the first operation) that indicates that a first operation (e.g., transmitting data to the first external device (e.g., data handing off media from the computer system to the first external device); retrieving media or information about media currently playing on the first external device (e.g., to play back on the computer system) will be performed when the second threshold distance is reached. The feedback varies (e.g., generating the feedback includes varying the feedback) based at least in part on a distance of the computer system to the first external device (e.g., based on distance of the computer system to the first external device, and a direction of movement of the computer system relative to the first external device). Generating feedback that varies based at least in part on a distance of the computer system to the first external device and indicates that a first operation will be performed when the second threshold distance is reached provides instruction to a user of the computer system for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen) and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     Generating the feedback includes, in accordance with a determination that the change in distance includes movement of the computer system (e.g.,  600 ) toward the first external device (e.g.,  605 ) (e.g., the change in distance includes a decrease in the distance between the computer system and the first external device (in some embodiments, while remaining between the first threshold distance and the second threshold distance (e.g., the computer system is located at a first distance from the first external device, between the first threshold distance and the second threshold distance))), the computer system changes ( 708 ) a current value for a feedback parameter of the feedback in a first direction (e.g., in a first manner (e.g., increasing; decreasing)) (e.g., increasing an audio volume (e.g., at the first external device); decreasing an audio volume (e.g., at the computer system), increasing a tactile output frequency, increasing a tactile output amplitude, increasing a size of a user interface element, and/or increasing a brightness of a user interface element). 
     Generating the feedback includes, in accordance with a determination that the change in distance includes movement of the computer system (e.g.,  600 ) away from the first external device (e.g.,  605 ) (e.g., the change in distance includes an increase in the distance between the computer system and the first external device (in some embodiments, while remaining between the first threshold distance and the second threshold distance (e.g., the computer system is located at a second distance from the first external device, between the first threshold distance and the second threshold distance and greater than the first distance from the first external device))), the computer system changes ( 710 ) the current value for the feedback parameter of the feedback in a second direction that is different from the first direction (e.g., in a second manner (e.g., decreasing; increasing)) (e.g., decreasing an audio volume (e.g., at the first external device); increasing an audio volume (e.g., at the computer system), decreasing a tactile output frequency, decreasing a tactile output amplitude, decreasing a size of a user interface element, and/or decreasing a brightness of a user interface element). 
     In response to detecting the change in distance, in accordance with a determination that the current distance of the computer system (e.g.,  600 ) from the first external device (e.g.,  605 ) is less than the second threshold distance (e.g.,  610 - 2 ), the computer system performs ( 712 ) the first operation (e.g., transmitting data to the first external device (e.g., data handing off media from the computer system to the first external device); retrieving media or information about media currently playing on the first external device (e.g., to play back on the computer system) (in some embodiments, performing the first operation and ceasing to vary the current value for the feedback parameter based on movement of the computer system relative to the first external device (e.g., ceasing to generate the feedback; disabling varying the current value for the feedback parameter based on movement of the computer system relative to the first external device)). In some embodiments, in accordance with a determination that the current distance of the computer system from the first external device is greater than the first threshold distance (e.g.,  610 - 1 ) and the second threshold distance (e.g.,  610 - 2 ), the computer system forgoes generating feedback (e.g., at the computer system; at the first external device) and forgoes performing the first operation. 
     In some embodiments, the computer system (e.g.,  600 ) is in communication with a display generation component (e.g.,  601 ) (e.g., a display controller, a touch-sensitive display system). In some embodiments, generating feedback includes displaying, via the display generation component, a first visual feedback (e.g.,  603 - 1 ;  603 - 2 ;  603 - 3 ;  615 ;  615 - 1 ;  615 - 2 ;  615 - 3 ) (e.g., at the computer system). In some embodiments, the first visual feedback includes blurring a user interface (e.g.,  603 ) and/or user interface object. In some embodiments, the first visual feedback includes displaying an indication of content (e.g.,  615 - 3 ) (e.g., media content). In some embodiments, the first visual feedback includes displaying a user interface object (e.g.,  615 ) (e.g., an affordance) that includes an indication (e.g.,  615 - 2 ) of the first external device (e.g.,  605 ) and, optionally, status information (e.g.,  615 - 1 ) for the first external device. In some embodiments, the visual feedback is optionally gradually modified or generated and is based, for example, on movement of the computer system toward or away from the first external device. For example, as the computer system moves toward the first external device, the visual feedback gradually increases (e.g., a degree of blur gradually increases, the size of a user interface object gradually increases, a user interface object gradually moves toward another user interface object), and as the computer system moves away from the first external device, the visual feedback gradually decreases (e.g., a degree of blur gradually decreases, the size of a user interface object gradually decreases, a user interface object gradually moves away from another user interface object). Displaying a first visual feedback provides instruction to a user of the computer system for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen) and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including increasing an amount (e.g., degree) of blur (e.g.,  603 - 1 ;  603 - 2 ;  603 - 3 ) (e.g., decreasing resolution) of at least a portion of a user interface (e.g.,  603 ) (e.g., increasing blurriness of a user interface and/or one or more objects displayed on the user interface). In some embodiments, the feedback parameter is blurriness (e.g., resolution). In some embodiments, changing the current value for the feedback parameter in the second direction includes decreasing the amount of blur (e.g., increasing resolution) of at least a portion of the user interface. In some embodiments, increasing the amount of blur of at least a portion of a user interface includes increasing blurriness of a background user interface without changing a blurriness of a user interface object (e.g., the background increases in blurriness while the pill affordance remains unchanged (with respect to blurriness)). 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including increasing a size (e.g., expanding; enlarging) of a first user interface object (e.g.,  615 ) (e.g., an affordance; representing a “pill” view of a media control user interface). In some embodiments, the feedback parameter is size. In some embodiments, changing the current value for the feedback parameter in the second direction includes decreasing the size of the first user interface object. 
     In some embodiments, while the computer system (e.g.,  600 ) is a first distance from the first external device (e.g., a distance depicted in diagram  610  of  FIG.  6 D ), and while displaying the first user interface object (e.g.,  615 ) having a first state (e.g., a state in which the first user interface object has the “pill” view appearance; a state in which first information is displayed in the first user interface object, but second information is not; a state in which controls for the first external device are not displayed in the first user interface object) and a first size (e.g., a size shown in  FIG.  6 D ), the computer system detects a second change in distance. In accordance with a determination that the current distance (e.g., the current distance after the second change in distance) of the computer system from the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 1 ) but greater than the second threshold distance (e.g.,  610 - 2 ): in accordance with a determination that the current distance is a second distance from the first external device (e.g., a distance depicted in diagram  610  of  FIG.  6 F ), wherein the second distance is less than the first distance, the computer system displays the first user interface object having the first state and a second size greater than the first size (e.g., see pill  615  in  FIG.  6 F ) (e.g., increasing the user interface object from the first size to the second size, while maintaining the first state of the user interface object); and in accordance with a determination that the current distance is a third distance from the first external device (e.g., a distance depicted in diagram  610  of  FIG.  6 E ), wherein the third distance is less than the second distance, displaying the first user interface object having the first state and a third size greater than the second size (e.g., see pill  615  in  FIG.  6 E ) (e.g., increasing the user interface object from the first or second size to the third size, while maintaining the first state of the user interface object). Displaying the first user interface object having the first state with the first, second, or third sizes based on the current distance from the first external device provides instruction to a user of the computer system for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen) and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In accordance with a determination that the current distance (e.g., after the second change in distance) of the computer system (e.g.,  600 ) from the first external device (e.g.,  605 ) is less than the second threshold distance (e.g.,  610 - 2 ), the computer system displays the first user interface object (e.g.,  615 ) transitioning (e.g., see controls interface  612 ′ in  FIG.  6 H ) from the first state (e.g., pill  615 ) to a second state (e.g., controls interface  612  and  612 ′) different from the first state (e.g., a state in which the first user interface object no longer has the “pill” view appearance; a state in which the first user interface object has a full-screen or card appearance; a state in which both first information and second information is displayed in the first user interface object; a state in which controls (e.g.,  612 - 1 ) for the first external device are displayed in the first user interface object) (e.g., the first user interface object increases in size when transitioning to the second state). Displaying the first user interface object transitioning from the first state to the second state when the current distance is less than the second threshold distance provides feedback to a user of the computer system indicating that the movement toward the first external device has caused the computer system to perform the first operation. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the first user interface object (e.g.,  615 ) progressively expands as the computer system (e.g.,  600 ) is between the first (e.g.,  610 - 1 ) and second (e.g.,  610 - 2 ) threshold distances and moving towards the first external device (e.g.,  605 ) (and, in some embodiments, progressively contracts as the computer system moves away from the first external device). In some embodiments, when the computer system reaches the second threshold distance, the first user interface object transitions (e.g., “pops”) to a card appearance (e.g.,  612 ′). 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including increasing a size (e.g., expanding; enlarging) of a representation (e.g.,  615 - 2 ) (e.g., an image; an indication) of the first external device (e.g.,  605 ). Increasing a size of a representation of the first external device provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the representation of the first external device is included in the first user interface object (e.g.,  615 ) (e.g., the pill affordance). In some embodiments, changing the current value for the feedback parameter in the second direction includes decreasing the size of the representation of the first external device. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including displaying a representation (e.g.,  615 - 3 ) (e.g., an image; an indication; text; album artwork; text identifying the media content) of media content moving toward a representation (e.g.,  615 - 2 ) (e.g., an image; an indication) of the first external device (e.g.,  605 ). Displaying a representation of media content moving toward a representation of the first external device provides feedback to a user of the computer system that the first operation is associated playing media at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the feedback parameter is a displayed position of the representation of the media content with respect to a representation of the first external device. In some embodiments, changing the current value for the feedback parameter in the second direction includes displaying the representation of the media moving away from the representation of the first external device. 
     In some embodiments, the computer system (e.g.,  600 ) generates feedback, including causing display of a second visual feedback (e.g.,  607 ) at the first external device (e.g.,  605 ). Causing display of a second visual feedback at the first external device provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the second visual feedback includes displaying or modifying a graphical element (e.g.,  605 - 2 ) at the first external device. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including causing an increase in one or more of: a) a size of the first set of one or more graphical elements (e.g., a size of light  607 ) displayed at the first external device (e.g.,  605 ) (e.g., causing an increasing number of light elements (e.g.,  605 - 2 ) to activate (e.g., glow) at the first external device); and b) a brightness (e.g., increasing size and/or brightness) of the first set of one or more graphical elements displayed at the first external device (e.g., the glow of one or more light elements at the first external device gets brighter and/or larger as the computer system moves toward the first external device). Causing an increase in at least one of a size or brightness of a first set of one or more graphical elements displayed at the first external device provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the feedback parameter is a size and/or brightness of an active region of one or more light elements (e.g., LEDs) at the first external device. In some embodiments, changing the current value for the feedback parameter in the second direction includes decreasing the size and/or brightness of the first set of one or more graphical elements at the first external device. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter in the first direction, including causing a change in a set of one or more colors of a second set (e.g., the first set) of one or more graphical elements (e.g., light  607 ) displayed at the first external device (e.g.,  605 ) (e.g., the glow of one or more light elements at the first external device changes colors as the computer system moves toward the first external device). In some embodiments, the feedback parameter is a color of an active region of one or more light elements (e.g., LEDs) at the first external device. In some embodiments, changing the current value for the feedback parameter in the first direction includes changing the set of one or more colors to a first set of one or more colors (e.g., colors that correspond to a media item (e.g., colors that match album art associated with a song)). In some embodiments, changing the current value for the feedback parameter in the second direction includes changing the set of one or more colors to a second set of one or more colors different from the first set of one or more colors. 
     In some embodiments, the first operation is associated with a type of media (e.g., playback of music; playback of a communication media (e.g., a phone call)). In some embodiments, the computer system (e.g.,  600 ) causes a change in the set of one or more colors of the second set of one or more graphical elements (e.g., light  607 ) displayed at the first external device (e.g.,  605 ), including: in accordance with a determination that the media is a first type (e.g., music), causing the set of one or more colors to have a first set of one or more colors (e.g., white) (e.g., see light  607  in  FIG.  6 B ); and in accordance with a determination that the media is a second type (e.g., a phone call) different from the first type, causing the set of one or more colors to have a second set of one or more colors (e.g., green) different from the first set of one or more colors (e.g., see light  607  in  FIG.  6 X ). Causing the set of one or more colors to have a first or second set of one or more colors depending on whether the media is a first or second type provides feedback to a user of the computer system that the first operation is associated with playback of a specific type of media at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the first operation is associated with playback of audio content (e.g.,  602 A;  602 B;  604 A;  604 B). In some embodiments, the computer system (e.g.,  600 ) causes display of the second visual feedback (e.g., light  607 ) at the first external device (e.g.,  605 ), including causing a change in (e.g., modulating) a visual characteristic (e.g., pulse frequency, brightness, color) of the visual feedback (e.g.,  607 ) based on an audio characteristic (e.g., volume, frequency, beat) of the audio content. Causing a change in a visual characteristic of the visual feedback based on an audio characteristic of the audio content provides feedback to a user of the computer system that the first operation is associated with playback of the audio content at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) is in communication with a tactile output generator (e.g.,  167 ) (e.g., a linear actuator; eccentric rotating mass actuator). In some embodiments, generating feedback includes generating, via the tactile output generator, a tactile output (e.g.,  606 ;  613 ;  616 ) (audio output is optionally generated in coordination with the tactile output) at the computer system. Generating a tactile output at the computer system provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including increasing at least one of a magnitude, frequency, and/or rate of repetition (e.g., increasing the magnitude and/or frequency of vibration) of the tactile output (e.g.,  606 ;  613 ;  616 ). In some embodiments, the computer system changes the current value for the feedback parameter of the feedback in the second direction, including decreasing at least one of the magnitude, frequency, and/or rate of repetition (e.g., decreasing the magnitude and/or frequency of vibration) of the tactile output. In some embodiments, the feedback parameter is a magnitude, frequency, and/or rate of repetition of the tactile output. Increasing or decreasing at least one of a magnitude, frequency, and/or rate of repetition of the tactile output depending on whether the change in direction includes movement of the computer system toward or away from the first external device provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation and the continued movement away from the first external device will cause the computer system not to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) changes a current value for the feedback parameter of the feedback in the first direction, including: in accordance with a determination that the movement of the computer system toward the first external device (e.g.,  605 ) includes a first velocity of movement, the computer system changes the current value for the feedback parameter of the feedback in the first direction by a first amount (e.g., see tactile output  606  in  FIG.  6 B / 6 D) (e.g., increasing the frequency, magnitude, and/or rate of repetition of the tactile output by a first amount); and in accordance with a determination that the movement of the computer system toward the first external device includes a second velocity of movement different from the first velocity, changing the current value for the feedback parameter of the feedback in the first direction by a second amount different than the first amount (e.g., see tactile output  613  in  FIG.  6 E ) (e.g., increasing the frequency, magnitude, and/or rate of repetition of the tactile output by a second amount). Changing the current value for the feedback parameter of the feedback in the first direction by a first amount or a second amount depending on whether the movement of the computer system toward the first external device includes a first or second velocity of movement provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), encourages continued movement of the computer system toward the first external device by correlating the tactile output with the velocity of movement toward the first external device, and provides varying levels of feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the first velocity of movement is greater than the second velocity of movement, and the first amount is greater than the second amount. Thus, when the velocity of movement is greater, the feedback parameter (e.g., frequency, rate of repetition, and/or magnitude) of the tactile output is increased at a greater rate, and when the velocity of movement is less, the feedback parameter of the tactile output is increased at a lesser rate. 
     In some embodiments, the computer system (e.g.,  600 ) changes a current value for the feedback parameter of the feedback in the first direction (e.g., or the second direction), including: in accordance with a determination that the movement of the computer system toward the first external device (e.g.,  605 ) includes at least a first threshold amount of movement toward the first external device (e.g., or away from the first external device) (e.g., see diagram  610  in  FIG.  6 E  or  FIG.  6 F ), the computer system changes the current value for the feedback parameter of the feedback in the first direction (e.g., or second direction) based on the current distance of the computer system from the first external device (e.g., if the computer system is a first distance from the first external device, changing the current value for the feedback parameter of the feedback in the first direction by a first amount, and if the computer system is a second (different) distance from the first external device, changing the current value for the feedback parameter of the feedback in the first direction by a second amount different than the first amount). In some embodiments, the computer system changes a current value for the feedback parameter of the feedback in the first direction (e.g., or the second direction), including: in accordance with a determination that the movement of the computer system toward the first external device (e.g., or away from the first external device) does not include at least the first threshold amount of movement toward the first external device (in some embodiments, movement towards the first external device is detected, but the movement is below the first threshold amount), forgoing changing the current value for the feedback parameter of the feedback in the first direction (e.g., or second direction) based on the current distance of the computer system from the first external device. Changing the current value for the feedback parameter of the feedback in the first direction based on the current distance of the computer system from the first external device, depending on whether or not the movement of the computer system toward the first external device includes at least a first threshold amount of movement toward the first external device, reduces the number of operations performed at the computer system, by reducing or eliminating feedback operations when movement of the computer system does not include at least the threshold amount of movement. Reducing the number of operations performed at the computer system reduces power usage, improves battery life, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the first operation is associated with playback of an audio signal (e.g.,  602 A;  602 B;  604 A;  604 B). In some embodiments, the computer system (e.g.,  600 ) generates the tactile output (e.g.,  606 ;  613 ;  616 ), including changing (e.g., modulating) a characteristic (e.g., a tactile characteristic; frequency, rate of repetition, and/or magnitude of the tactile output) of the tactile output based on an audio characteristic (e.g., volume, frequency, beat) of the audio signal. Changing a characteristic of the tactile output based on an audio characteristic of the audio signal provides feedback to a user of the computer system that the first operation is associated with playback of the audio signal at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) is in communication with an audio output device (e.g.,  111 ) (e.g., an internal or external speaker). In some embodiments, generating feedback includes generating, via the audio output device, a first audio feedback (e.g.,  602 A;  604 A) (e.g., adjusting an audio output) at the computer system. Generating a first audio feedback at the computer system provides instruction to a user of the computer system for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, including decreasing an output volume of audio output (e.g.,  602 A;  604 A) (e.g., currently output) at the computer system. Decreasing an output volume of audio output at the computer system provides feedback to a user of the computer system that the first operation is associated with playback of the audio, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the feedback parameter is the output volume of audio being output at the computer system. In some embodiments, changing the current value for the feedback parameter in the second direction includes increasing output volume of audio output at the computer system. In some embodiments, when the computer system is currently outputting audio while the current distance of the computer system from the first external device is less than the first threshold distance but greater than the second threshold distance, the computer system decreases the output volume of the audio when the computer system moves toward the first external device and increases the output volume of the audio when the computer system moves away from the first external device. 
     In some embodiments, while the first audio feedback (e.g.,  602 A;  604 A) is generated at the computer system (e.g.,  600 ), second audio feedback (e.g.,  602 B;  604 B) (e.g., adjusting an audio output) is generated at the first external device (e.g.,  605 ) (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system). Generating a second audio feedback at the first external device while the first audio feedback is generated at the computer system provides feedback to a user of the computer system that the first operation is associated with the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, while the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, an output volume of audio output (e.g., see  602 B- 3  in  FIG.  6 G ) (e.g., currently output) increases at the first external device (e.g.,  605 ) (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system). Increasing an output volume of audio output at the first external device while changing the current value for the feedback parameter of the feedback in the first direction provides feedback to a user of the computer system that the first operation is associated with playback of audio at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the feedback parameter is the output volume of audio (e.g.,  602 B;  604 B) being output at the first external device (e.g.,  605 ). In some embodiments, the computer system (e.g.,  600 ) changing the current value for the feedback parameter in the second direction includes decreasing output volume of audio output at the first external device. In some embodiments, when the computer system is currently outputting audio and the first external device is not outputting audio, and when the current distance of the computer system from the first external device transitions from a distance greater than the first threshold distance and the second threshold distance to a distance that is less than the first threshold distance but greater than the second threshold distance, audio begins to play at the first external device (e.g., while continuing to play at the computer system). While the current distance of the computer system from the first external device is less than the first threshold distance but greater than the second threshold distance, the output volume of the audio at the first external device is increased (e.g., while the output volume of the audio at the computer system decreases) when the computer system moves toward the first external device and is decreased (e.g., while the output volume of the audio at the computer system increases) when the computer system moves away from the first external device. 
     In some embodiments, when the first external device (e.g.,  605 ) is currently outputting audio (e.g.,  602 B;  604 B) while the current distance of the computer system (e.g.,  600 ) from the first external device is less than the first threshold distance (e.g.,  610 - 1 ) but greater than the second threshold distance (e.g.,  610 - 2 ), the output volume of the audio at the first external device is decreased when the computer system moves toward the first external device and is increased when the computer system moves away from the first external device. In some embodiments, when the first external device is currently outputting audio and the computer system is not outputting audio, and when the current distance of the computer system from the first external device transitions from a distance greater than the first threshold distance and the second threshold distance to a distance that is less than the first threshold distance but greater than the second threshold distance, audio begins to play at the computer system (e.g., while continuing to play at the first external device). While the current distance of the computer system from the first external device is less than the first threshold distance but greater than the second threshold distance, the output volume of the audio (e.g.,  602 A;  604 A) at the computer system is increased (e.g., while the output volume of the audio at the first external device decreases) when the computer system moves toward the first external device and is decreased (e.g., while the output volume of the audio at the first external device increases) when the computer system moves away from the first external device. 
     In some embodiments, while the computer system (e.g.,  600 ) changes the current value for the feedback parameter of the feedback in the first direction, an equalization setting of audio output (e.g.,  602 B;  604 B) (e.g., currently output) is adjusted at the first external device (e.g.,  605 ) (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system). Adjusting an equalization setting of audio output at the first external device while changing the current value for the feedback parameter of the feedback in the first direction provides feedback to a user of the computer system that the first operation is associated with playback of audio output at the first external device, provides instruction to the user for action needed to cause the computer system to perform the first operation without requiring additional inputs from the user (e.g., input at a touchscreen), and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to perform the first operation. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the feedback parameter is an equalization setting that affects audio properties that determine the fullness of the audio output at the first external device. In some embodiments, changing the current value for the feedback parameter in the first direction includes adjusting the equalization setting in a first manner such that the audio output at the first external device increases in fullness. In some embodiments, changing the current value for the feedback parameter in the second direction includes adjusting the equalization setting in a second manner such that the audio output at the first external device decreases in fullness. In some embodiments, when the first external device is currently outputting audio while the current distance of the computer system from the first external device is less than the first threshold distance but greater than the second threshold distance, the equalization setting of the audio output at the first external device changes such that the audio properties smoothly transition from having a tinny sound (e.g., having audio properties similar to audio produced from a low-power speaker (e.g., a speaker of a smartphone)) to having a full, rich sound as the computer system moves toward the first external device. Conversely, the equalization setting of the audio output at the first external device changes such that the audio properties smoothly transition from the full, rich sound to the tinny sound as the computer system moves away from the first external device. 
     In some embodiments, the computer system (e.g.,  600 ) is in communication with a tactile output generator (e.g.,  167 ) (e.g., a linear actuator; eccentric rotating mass actuator). In some embodiments, generating the feedback includes: in accordance with a determination that a first set of criteria is met, generating, via the tactile output generator, a first tactile output (e.g.,  606 ;  613 ) (audio output is optionally generated in coordination with the tactile output) at the computer system; and in accordance with a determination that the first set of criteria is not met, forgoing generating the first tactile output (in some embodiments, generating a non-tactile output such as an audio output and/or a visual output) at the computer system (e.g., see  FIG.  6 F ). In some embodiments, tactile output is generated (or not) depending on an operational state of the computer system. For example, in some embodiments, the feedback does not include tactile output when the computer system (e.g., a battery of the computer system) is being charged. As another example, in some embodiments, the feedback does not include tactile output when the computer system is stationary (e.g., the computer system is not being moved) (e.g., the computer system has been placed on a surface such as a table). As yet another example, in some embodiments, the feedback does not include tactile output when the computer system is positioned in a particular manner such as, for example, when the computer system is positioned away from the first external device (e.g., as illustrated in  FIG.  6 F ). 
     In some embodiments, the first set of criteria is not met when the computer system (e.g.,  600 ) is in a charging state (e.g., a battery of the computer system is being charged). In some embodiments, the first set of criteria is not met when the computer system is stationary for a predetermined amount of time (e.g., the computer system is not being moved). In some embodiments, the first set of criteria is not met when a predetermined portion of the computer system (e.g.,  600 - 1 ) (e.g., a display screen, a top surface, a user-facing surface) is positioned (e.g., oriented) away (e.g., facing away) from the external device (e.g., see  FIG.  6 F ). 
     In some embodiments, in response to detecting the change in distance: in accordance with a determination that the current distance of the computer system (e.g.,  600 ) from the first external device (e.g.,  605 ) is less than the second threshold distance (e.g.,  610 - 2 ), the computer system ceases to vary the current value for the feedback parameter based on movement of the computer system relative to the first external device (e.g., ceasing to generate the feedback; disabling varying the current value for the feedback parameter based on movement of the computer system relative to the first external device) (e.g., see  FIGS.  6 J- 6 L ). Ceasing to vary the current value for the feedback parameter based on movement of the computer system relative to the first external device when the current distance of the computer system from the first external device is less than the second threshold distance provides feedback to a user of the computer system that the first operation has been performed as a result of the prior movement of the computer system with respect to the first external device. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, after ceasing to vary the current value for the feedback parameter based on movement of the computer system (e.g.,  600 ) relative to the first external device (e.g.,  605 ) (e.g., after performing the first operation; after disabling varying the current value for the feedback parameter based on movement of the computer system relative to the first external device), the computer system detects a third change in distance between the computer system and the first external device. In response to detecting the third change in distance: in accordance with a determination that the current distance (e.g., the current distance after detecting the third change in distance) of the computer system from the first external device is greater than a third threshold distance (e.g.,  610 - 1 ) (e.g., a predetermined threshold distance; the outer threshold distance; the first threshold distance; the first threshold distance plus a variance (e.g., 45%/50%/60% of the first threshold distance)), varying (e.g., re-enabling varying) the current value for the feedback parameter based on movement of the computer system relative to the first external device (e.g., see  FIGS.  6 L and  6 M ). In response to detecting the third change in distance: in accordance with a determination that the current distance (e.g., the current distance after detecting the third change in distance) of the computer system from the first external device is less than the third threshold distance, forgoing varying the current value for the feedback parameter based on movement of the computer system relative to the first external device (e.g., continuing to cease varying the current value for the feedback parameter based on movement of the computer system relative to the first external device) (e.g., see  FIGS.  6 J and  6 K ). Selectively enabling varying the current value for the feedback parameter based on movement of the computer system relative to the first external device depending on whether the computer system has moved beyond the third threshold distance prevents the computer system from generating unwanted or unnecessary feedback by ensuring that a user of the computer system intentionally desires to re-enable the feedback, as indicated by moving the computer system beyond the third threshold distance. Preventing the computer system from generating unwanted or unnecessary feedback conserves computational resources, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) performs the first operation, including: in accordance with a determination that a second set of criteria is met, wherein the second set of criteria includes a criterion that is met when the computer system is currently playing (e.g., outputting audio and/or displaying video (e.g., at the computer system)) first media (e.g.,  602 A) (e.g., audio and/or video media), the computer system initiates playback of the first media at the first external device (e.g.,  605 ), including: decreasing a first audio characteristic (e.g., a volume, an equalization setting) of the first media at the computer system (e.g., see  602 A- 4 ,  602 A- 3 ,  602 A- 2 , and/or  602 A- 1  in  FIGS.  6 D- 6 H ); and while decreasing the first audio characteristic of the first media at the computer system, causing an increase of a second audio characteristic (e.g., the first audio characteristic, a volume, an equalization setting) of the first media at the first external device (e.g., see  602 B- 1 ,  602 B- 2 ,  602 B- 3 ,  602 B- 4 , and/or  602 B- 5  in  FIGS.  6 D- 6 I ) (e.g., crossfading handoff of the first media from the computer system to the first external device, which, in some embodiments, includes gradually decreasing the output volume of the first media at the computer system, while simultaneously gradually increasing the output volume of the first media at the first external device). Causing an increase of a second audio characteristic of the first media at the first external device while decreasing the first audio characteristic of the first media at the computer system provides feedback to a user of the computer system that the first operation is associated with playback of the first media at the first external device, and provides feedback to the user that the first operation has been performed so that the user no longer attempts to execute the first operation (e.g., by providing inputs on a touchscreen or continuing to move the computer system), thereby reducing the number of inputs at the computer system. Providing improved feedback and reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, after the computer system (e.g.,  600 ) performs the first operation (e.g., transmitting data to the first external device (e.g., data handing off media from the computer system to the first external device); retrieving media or information about media currently playing on the first external device (e.g., to play back on the computer system), one or more of a size or brightness (e.g., reducing the size and/or brightness) of a third set of one or more graphical elements (e.g., light  607 ;  605 - 2 ) displayed at the first external device (e.g.,  605 ) is reduced (e.g., see  FIG.  6 I ) (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system) (e.g., the glow of one or more light elements at the first external device gets dimmer and/or smaller in size after the first operation is performed). Reducing one or more of a size or brightness of a third set of one or more graphical elements displayed at the first external device after performing the first operation provides feedback to a user of the computer system that the first operation is associated with the first external device, and provides feedback to the user that the first operation has been performed so that the user no longer attempts to execute the first operation (e.g., by providing inputs on a touchscreen or continuing to move the computer system), thereby reducing the number of inputs at the computer system. Providing improved feedback and reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the glow of the set of one or more light elements at the first external device increase in brightness and/or size as the computer system approaches the first external device, until reaching the second threshold distance. In some embodiments, when the first operation is performed (e.g., media is handed off from the computer system to the first external device, or from the first external device to the computer system), the set of one or more graphical elements have a high brightness and/or large size and, after the first operation is performed, the set of one or more graphical elements fade in brightness and/or size (e.g., to an “off” setting). 
     In some embodiments, after the computer system (e.g.,  600 ) performs the first operation (e.g., transmitting data to the first external device (e.g., data handing off media from the computer system to the first external device); retrieving media or information about media currently playing on the first external device (e.g., to play back on the computer system), an equalization setting of audio output (e.g.,  602 B;  604 B) (e.g., currently output) at the first external device (e.g.,  605 ) is adjusted (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system) (e.g., causing the equalization setting of the audio output at the first external device to change such that the audio properties smoothly transition from having a tinny sound to having a full, rich sound). Adjusting an equalization setting of an audio output at the first external device after performing the first operation provides feedback to a user of the computer system that the first operation is associated with playback of the audio at the first external device, and provides feedback to the user that the first operation has been performed so that the user no longer attempts to execute the first operation (e.g., by providing inputs on a touchscreen or continuing to move the computer system), thereby reducing the number of inputs at the computer system. Providing improved feedback and reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, while the first external device (e.g.,  605 ) is currently playing (e.g., outputting audio and/or displaying video) second media (e.g.,  602 B) (e.g., audio and/or video media), the computer system (e.g.,  600 ) detects a fourth change in distance between the computer system and the first external device (e.g., see diagram  610  in  FIG.  6 L ). In response to detecting the fourth change in distance, and in accordance with a determination that the current distance (e.g., the current distance after detecting the fourth change in distance) of the computer system from the first external device is greater than a fourth threshold distance (e.g.,  610 - 1 ) (e.g., a predetermined threshold distance; the outer threshold distance; the first threshold distance; the first threshold distance plus a variance (e.g., 45%/50%/60% of the first threshold distance)): in accordance with a determination that the second media is a first type of media (e.g., communication audio (e.g., a phone call, audio from a video communication)), playback of the second media at the first external device ceases (e.g., in response to instruction(s) from the first external device; in response to instruction(s) from the computer system) (e.g., initiating a process to cause the computer system to playback the second media (e.g., handing off the playback of the second media from the first external device to the computer system)); and in accordance with a determination that the second media is a second type of media different from the first type (e.g., music; a podcast; non-communication session audio), playback of the second media at the first external device continues (e.g., see  FIG.  6 L ). Continuing or ceasing playback of the second media at the first external device when the computer system moves beyond a fourth threshold distance from the first external device automatically performs an operation without requiring a user of the computer system to provide additional input (e.g., input to continue or cease playing the second media at the first external device). Performing an operation without requiring additional inputs enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. Additionally, ceasing playback of the second media at the first external device when the second media is the first type of media (e.g., a phone call) preserves privacy of the user of the computer system by ensuring that the first type of media is not being played back at the first external device without the user&#39;s knowledge. 
     Note that details of the processes described above with respect to method  700  (e.g.,  FIG.  7   ) are also applicable in an analogous manner to the methods described below. For example, methods  800 ,  1000 , and  1200  optionally include one or more of the characteristics of the various methods described above with reference to method  700 . For example, these methods can include providing dynamic feedback based on movement of the computer system relative to the first external device, as discussed in method  700 . For brevity, these details are not repeated below. 
       FIG.  8    is a flow diagram illustrating a method for managing media playback devices using an electronic device in accordance with some embodiments. Method  800  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 ) a display (e.g.,  601 ) and one or more input devices (e.g.,  601 ;  112 ). Some operations in method  800  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     In some embodiments, the electronic device (e.g.,  600 ) is a computer system. The computer system is optionally in communication (e.g., wired communication, wireless communication) with a display generation component (e.g.,  601 ) (e.g., a display controller, a touch-sensitive display system) and with one or more input devices (e.g.,  601 ;  112 ) (e.g., a touch-sensitive surface). The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. The one or more input devices are configured to receive input, such as a touch-sensitive surface receiving user input. In some embodiments, the one or more input devices are integrated with the computer system. In some embodiments, the one or more input devices are separate from the computer system. Thus, the computer system can transmit, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content (e.g., using a display device) and can receive, a wired or wireless connection, input from the one or more input devices. 
     As described below, method  800  provides an intuitive way for managing media playback devices. The method reduces the cognitive burden on a user for managing media playback devices, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage media playback devices faster and more efficiently conserves power and increases the time between battery charges. 
     In method  800 , in response to a determination ( 802 ) that a distance between the computer system (e.g.,  600 ) and a first external device (e.g.,  605 ) (e.g., a smart speaker; a media playback device (e.g., a digital media player); a smartphone; a smartwatch) is less than (e.g., is now less than; has transitioned and/or changed to be less than) a first threshold distance (e.g.,  610 - 1 ;  610 - 2 ) (e.g., a predetermined threshold distance (e.g., 6 inches, 12 inches, 18 inches); an outer threshold distance from the first external device; an inner threshold distance from the first external device (e.g., 4 inches, 8 inches, 12 inches)), the computer system performs steps  804 - 812  of method  800 . 
     In accordance with a determination that a first set of criteria is met, wherein the first set of criteria includes a criterion that is met when the computer system (e.g.,  600 ) is currently playing (e.g., outputting audio and/or displaying video (e.g., at the computer system) or causing a connected device to output audio and/or display video) first media (e.g.,  604 A) (e.g., audio and/or video media) and the first external device (e.g.,  605 ) is playing second media (e.g.,  602 B) (e.g., audio and/or video media) (e.g., the computer system and the first external device are simultaneously outputting different audio), the computer system displays ( 804 ) a media control user interface (e.g.,  612 ;  612 ). The media control interface includes (e.g., concurrently includes) a first selectable graphical user interface object (e.g.,  626 ) for starting playback of the first media (e.g.,  604 A) on the first external device (e.g., a “transfer from phone” affordance); and one or more selectable user interface objects (e.g.,  612 - 1 ) for controlling the playback of the second media on the first external device (e.g., the objects, when selected, control playback). The one or more selectable user interface objects include a first media control selectable graphical user interface object (e.g.,  612 - 1   a ;  612 - 1   b ) (e.g., a play affordance, a pause affordance, a next track affordance, a previous track affordance, a volume affordance, and/or an audio scrubber). Displaying a media control user interface that, when the computer system is currently playing first media and the first external device is playing second media, includes a first selectable graphical user interface object for starting playback of the first media on the first external device and one or more selectable user interface objects for controlling the playback of the second media on the first external device, including a first media control selectable graphical user interface object, provides feedback to a user of the computer system of a first function that can be performed that starts playback of the first media on the first external device, and a second function that can be performed that controls playback of the second media on the first external device, without requiring further input from the user to navigate between different user interfaces to access each of these separate functions. Moreover, the computer system automatically displays the media control user interface having the first selectable graphical user interface object and the one or more selectable user interface objects when a set of conditions are met, without requiring further input from the user to access and navigate between different user interfaces to access the first selectable graphical user interface object and the one or more selectable user interface objects. Providing improved feedback and performing an operation automatically when a set of conditions is met reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) displays the media control user interface (e.g.,  612 ;  612 ) in response to determining that the distance between the computer system and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 2 ) (e.g., when the first threshold distance is an inner threshold distance from the first external device). In some embodiments, the computer system displays the media control user interface in response to an input (e.g.,  608 ) on a user interface object (e.g.,  615 ) that is displayed when the distance between the computer system and the first external device is less than the first threshold distance (e.g.,  610 - 1 ) and greater than a second threshold distance (e.g.,  610 - 2 ) (e.g., when the first threshold distance is an outer threshold distance from the first external device and the second threshold distance is an inner threshold distance from the first external device). 
     While displaying the media control user interface (e.g.,  612 ), the computer system (e.g.,  600 ) receives ( 806 ), via the one or more input devices (e.g.,  601 ), an input (e.g.,  628 ;  630 ) (e.g., a touch input). 
     In response ( 808 ) to receiving the input (e.g.,  628 ;  630 ), and in accordance with a determination that the input (e.g.,  630 ) corresponds to the first selectable graphical user interface object (e.g.,  626 ) (e.g., the input is a selection of the “transfer from phone” affordance), the computer system (e.g.,  600 ) initiates ( 810 ) a process to cause the first external device (e.g.,  605 ) to playback the first media (e.g., device  605  begins playing music  604 B in  FIG.  6 T ) (e.g., initiating a process for outputting the first media at the first external device (e.g., handing off the playback of the first media from the computer system to the first external device)) (in some embodiments, ceasing playback of the second media at the first external device) (e.g., adding the first media to a queue for playback at the first external device). In some embodiments, playing back the first media at the first external device includes ceasing playback of the first media at the computer system. 
     In response ( 808 ) to receiving the input (e.g.,  628 ;  630 ), and in accordance with a determination that the input (e.g.,  628 ) corresponds to (e.g., is a selection of) the first media control selectable graphical user interface object (e.g.,  612 - 1   a ) (e.g., a pause affordance), initiating a process for controlling (e.g., modifying) playback of the second media (e.g.,  602 B) (e.g., the object, when selected, controls playback) by the first external device (e.g.,  605 ) (e.g., pausing playback of the second media at the first external device (e.g., see  FIG.  6 S )) (in some embodiments, while continuing to playback the first media at the computer system). 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 1 ), and in accordance with a determination that a second set of criteria is met, wherein the second set of criteria includes a criterion that is met when the computer system is not playing the first media (e.g.,  604 A) (e.g., the computer system is not causing playback of any media) and the first external device is not playing the second media (e.g.,  602 B) (e.g., the first external device is not causing playback of any media), the computer system displays, via the display generation component (e.g.,  601 ), a set of one or more representations of predetermined media content items (e.g.,  612 - 3 ) (e.g., the media control user interface includes the set of one or more representations of predetermined media content items) (e.g., a set of icons or images representing recommended or recently played songs or albums that can be selected to initiate playback of the corresponding song or album). Displaying a set of one or more representations of predetermined media content items when the computer system is not playing the first media and the first external device is not playing the second media provides feedback to a user of the computer system of a function that can be performed that starts playback of predetermined media, without requiring further input from the user to navigate to a user interface to select media for playback. Moreover, the computer system automatically displays the set of one or more representations of predetermined media content items when a set of conditions are met, without requiring further input from the user to access and navigate between different user interfaces to access representations of media content items. Providing improved feedback and performing an operation automatically when a set of conditions is met reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the method further comprises: while displaying the set of one or more representations of predetermined media content items (e.g.,  612 - 3 ), the computer system (e.g.,  600 ) receives, via the one or more input devices (e.g.,  601 ), an input directed to a first representation of a predetermined media content item; and in response to receiving the input directed to the first representation, initiates a process to cause the computer system and/or the first external device (e.g.,  605 ) to play media corresponding to the first representation. 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 1 ), and in accordance with a determination that a third set of criteria is met, wherein the third set of criteria includes a criterion that is met when the computer system is not playing the first media (e.g.,  604 A) (e.g., the computer system is not causing playback of any media) and the first external device is currently playing the second media (e.g.,  602 B) (e.g., see  FIG.  6 M ), the computer system displays, via the display generation component (e.g.,  601 ), a second selectable graphical user interface object (e.g.,  620 ) (e.g., the media control user interface includes the second selectable graphical user interface object) that, when selected, initiates playback of the second media at the computer system (e.g., a “transfer to phone” affordance; an affordance for handing off media from the first external device to the computer system). Displaying, when the computer system is not playing the first media and the first external device is playing the second media, a second selectable graphical user interface object that, when selected, initiates playback of the second media at the computer system provides feedback to a user of the computer system of a function that can be performed that starts playback of the second media at the computer system without requiring further input from the user to navigate between different user interfaces to access controls to initiate playback of the second media at the computer system. Moreover, the computer system automatically displays the second selectable graphical user interface object when a set of conditions are met, without requiring further input from the user to access and navigate between different user interfaces to access the second selectable graphical user interface object. Providing improved feedback and performing an operation automatically when a set of conditions is met reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the method further comprises: while displaying the second selectable graphical user interface object (e.g.,  620 ), the computer system (e.g.,  600 ) receives, via the one or more input devices (e.g.,  601 ), an input directed to the second selectable graphical user interface object; and in response to receiving the input directed to the second selectable graphical user interface object, initiates a process to cause the computer system to playback the second media (e.g.,  602 B). In some embodiments, the first external device continues playback of the second media when the second media is transferred to the computer system. In some embodiments, the first external device ceases playback of the second media when the second media is transferred to the computer system. In some embodiments, when the first external device hands off playback of the second media to the computer system, the first external device generates feedback to indicate the handoff process is initiated. For example, in some embodiments, the first external device includes lights, and the lights pulse and increase in brightness (and, optionally, in pulse frequency) when the handoff is initiated, and then the lights fade to an “off” setting when the handoff is complete. 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 2 ), and in accordance with a determination that a fourth set of criteria is met, wherein the fourth set of criteria includes a criterion that is met when the computer system is currently playing the first media (e.g.,  604 A) and the first external device is not playing the second media (e.g.,  602 B) (e.g., the first external device is not causing playback of any media), the computer system initiates a process to cause the first external device to playback the first media (e.g., see  FIGS.  6 G- 6 I ) (e.g., initiating a process for outputting the first media at the first external device (e.g., handing off the playback of the first media from the computer system to the first external device) without requiring further input (e.g., touch input) from a user of the computer system). Initiating a process to cause the first external device to playback the first media, when the computer system is currently playing the first media and the first external device is not playing the second media, allows the computer system to automatically initiate playback of the first media at the first external device without requiring further input from the user to initiate playback of the first media at the first external device. Performing an operation automatically when a set of conditions is met enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, playing back the first media at the first external device includes ceasing playback of the first media at the computer system. 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 1 ;  610 - 2 ), and in accordance with a determination that a fifth set of criteria is met, wherein the fifth set of criteria includes a first criterion that is met when the computer system is currently playing the first media (e.g.,  604 A) and the first external device is playing third media (e.g.,  602 B) (e.g., the second media) (e.g., the computer system and the first external device are simultaneously outputting different audio) and a second criterion that is met when the first media is different from the third media (e.g., the first and third media are different songs), the computer system adds the third media to a queue for playback at the computer system (e.g., the computer system continues to cause playback of the first media while the third media is added to the queue for future playback at the computer system). Adding the third media to a queue for playback at the computer system when the computer system is currently playing the first media and the first external device is playing third media that is different from the first media, allows the computer system to automatically add the third media to a playback queue of the computer system without requiring further input from the user to navigate various user interfaces to locate the third media (e.g., in a library of media items) and add it to the queue. Performing an operation automatically when a set of conditions is met enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the media control user interface (e.g.,  612 ) further includes a set of one or more selectable user interface objects (e.g.,  612 - 4 ;  612 - 6 ;  612 - 7 ) (e.g., timer controls; alarm controls; message controls) that includes a first selectable user interface object ( 612 - 6   a ;  612 - 6   b ;  612 - 7   a ) that, when selected, controls an operation at the first external device (e.g.,  605 ) (e.g., an operation associated with a timer at the first external device; an operation associated with an alarm at the first external device; an operation associated with a message at the first external device). Displaying a media control user interface that includes a first selectable user interface object that, when selected, controls an operation at the first external device provides feedback to a user of the computer system of a function that can be performed that controls an operation at the first external device, without requiring further input from the user to navigate between different user interfaces to access the function. Moreover, the computer system automatically displays the media control user interface having the first selectable user interface object when a set of conditions are met, without requiring further input from the user to access and navigate between different user interfaces to access the first selectable user interface object. Providing improved feedback and performing an operation automatically when a set of conditions is met reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the set of one or more selectable user interface objects includes a set of controls selected from a group consisting of timer controls (e.g.,  612 - 6 ) (e.g., controls for setting or adjusting a timer using the first external device), alarm controls (e.g.,  612 - 7 ) (e.g., controls for setting or adjusting an alarm using the first external device), and message controls (e.g.,  612 - 4 ) (e.g., controls for composing, sending, or reading a message using the first external device). 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than (e.g., is now less than; has transitioned and/or changed to be less than) a second threshold distance (e.g.,  610 - 1 ) (e.g., a predetermined threshold distance (e.g., 6 inches, 12 inches, 18 inches); an outer threshold distance from the first external device) (in some embodiments, in response to a determination that the distance between the computer system and the first external device is less than the second threshold distance and greater than the first threshold distance), the computer system displays, via the display generation component (e.g.,  601 ), a representation (e.g.,  615 ) (e.g., an affordance (selectable graphical user interface object) representing a “pill” view) of the media control user interface (e.g.,  612 ), wherein the representation of the media control user interface includes an indication (e.g.,  615 - 1 ;  615 - 2 ) of the first external device (e.g., text and/or images that represent the first external device). Displaying, when a distance between the computer system and the first external device is less than a second threshold distance, a representation of the media control user interface that includes an indication of the first external device provides feedback to a user of the computer system of a function that can be performed with respect to the first external device, without requiring further input from the user to navigate between different user interfaces to access functionality for the first external device. Moreover, the computer system automatically displays the representation of the media control user interface having the indication of the first external device, without requiring further input from the user. Providing improved feedback and performing an operation automatically when a set of conditions is met reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the indication of the first external device (e.g.,  605 ) includes first status information (e.g.,  615 - 1 ) associated with the first external device (e.g., text and/or images that indicate a current state or status of the first external device). In some embodiments, the status information includes an indication of whether media is being played back at the first external device, an indication of what media is being played back at the first external device, an indication of a type of media (e.g., call, music, podcast, voice command, virtual assistant) being played back at the first external device, and/or an indication of whether the first external device is turned on/off, connected/disconnected, and/or has sufficient power. 
     In some embodiments, the computer system (e.g.,  600 ) detects a first change in distance between the computer system and the first external device (e.g.,  605 ). In some embodiments, the change in distance is detected based on a change in signal strength (e.g., wireless signal strength) exchanged between the system and the first external device. In some embodiments, the change in distance is detected via one or more sensors (e.g., infrared sensors; optical sensors). In some embodiments, the change in distance is detected via data transmitted to the system from a Wi-Fi positioning system, from GPS, and/or from the first external device. In response to detecting the first change in distance, and in accordance with a determination that the first change in distance includes movement of the computer system toward the first external device (e.g., see  FIG.  6 E ) (e.g., the change in distance includes a decrease in the distance between the computer system and the first external device (in some embodiments, while remaining between the first threshold distance and the second threshold distance (e.g., the computer system is located at a first distance from the first external device, between the first threshold distance and the second threshold distance))), the computer system adjusts (e.g., increases) a displayed size of the representation (e.g.,  615 ) of the media control user interface (e.g., see  FIG.  6 E ). Adjusting a displayed size of the representation of the media control user interface when the first change in distance includes movement of the computer system toward the first external device provides instruction to a user of the computer system for action needed to cause the computer system display the media control user interface and provides feedback to the user indicating that continued movement toward the first external device will cause the computer system to display the media control user interface. Providing instruction for causing the computer system to perform an operation without requiring additional inputs and providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  600 ) detects a second change in distance between the computer system and the first external device (e.g.,  605 ). In some embodiments, the change in distance is detected based on a change in signal strength (e.g., wireless signal strength) exchanged between the system and the first external device. In some embodiments, the change in distance is detected via one or more sensors (e.g., infrared sensors; optical sensors). In some embodiments, the change in distance is detected via data transmitted to the system from a Wi-Fi positioning system, from GPS, and/or from the first external device. In response to detecting the second change in distance, and in accordance with a determination that the second change in distance includes movement of the computer system away from the first external device (e.g., see  FIG.  6 F ) (e.g., the second change in distance includes an increase in the distance between the computer system and the first external device (in some embodiments, while remaining between the first threshold distance and the second threshold distance (e.g., the computer system is located at a second distance from the first external device, between the first threshold distance and the second threshold distance and greater than the first distance from the first external device))), the computer system adjusts (e.g., decreases) a displayed size of the representation (e.g.,  615 ) of the media control user interface (e.g., see  FIG.  6 F ). Adjusting a displayed size of the representation of the media control user interface when the second change in distance includes movement of the computer system away from the first external device provides feedback to a user of the computer system indicating that continued movement away from the first external device will not cause the computer system to display the media control user interface. Providing improved feedback enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the representation of the media control user interface (e.g.,  615 ) includes a first subset of status information (e.g.,  615 - 1 ) associated with the first external device (e.g.,  605 ) (e.g., text and/or images that indicate a current state or status of the first external device). In some embodiments, while displaying the representation of the media control user interface, the computer system (e.g.,  600 ) receives a second input (e.g.,  608 ) (e.g., a touch input directed to the representation of the media control user interface; a change in the distance between the computer system and the first external device (e.g., the computer system moves closer to the first external device)). In response to receiving the second input, the computer system displays the representation of the media control user interface having an expanded state (e.g.,  612 ;  612 ) that includes a second subset of status information (e.g.,  612 - 2 ;  612 - 1 ) associated with the first external device that is different than the first subset of status information associated with the first external device (e.g., text and/or images that indicate a current state or status of the first external device) (e.g., status information that is not included in the first subset of status information). In some embodiments, the second subset of status information includes the first subset of status information plus additional status information. In some embodiments, displaying the representation of the media control user interface having an expanded state includes displaying an animation of the representation of the media control user interface expanding to display additional status information (e.g., the second subset of status information). In some embodiments, displaying the representation of the media control user interface having an expanded state includes displaying the representation of the media control user interface expanding to the media control user interface, wherein the second subset of status information is displayed in the media control user interface. In some embodiments, the expanded state of the representation of the media control user interface is the media control user interface. 
     In some embodiments, the computer system (e.g.,  600 ) displays the representation of the media control user interface having an expanded state (e.g.,  612 ′), including in accordance with a determination that a sixth set of criteria is met, wherein the sixth set of criteria includes a criterion that is met when the computer system is currently playing the first media (e.g.,  604 A) and the first external device (e.g.,  605 ) is not playing the second media (e.g.,  602 B) (e.g., the first external device is not causing playback of any media), the computer system displays a third selectable graphical user interface object (e.g.,  626 ) (e.g., the first selectable graphical user interface object) (e.g., a “transfer from phone” affordance) that, when selected, initiates playback of the first media on the first external device (e.g., the third selectable graphical user interface object is displayed without immediately handing off playback of the first media to the first external device). In some embodiments, the method further comprises: while displaying the third selectable graphical user interface object, receiving an input directed to the third selectable graphical user interface object; and in response to receiving the input directed to the third selectable graphical user interface object, initiating a process to cause the first external device to playback the first media (e.g., initiating a process for outputting the first media at the first external device (e.g., handing off the playback of the first media from the computer system to the first external device)). 
     In some embodiments, in response to a determination that a distance between the computer system (e.g.,  600 ) and the first external device (e.g.,  605 ) is less than the first threshold distance (e.g.,  610 - 2 ) (e.g., an inner threshold distance from the first external device (e.g., 4 inches, 8 inches, 12 inches)), the computer system displays second status information (e.g.,  612 - 2 ;  612 - 1 ) associated with the first external device (e.g., text and/or images that indicate a current state or status of the first external device). Displaying second status information associated with the first external device when the distance between the computer system and the first external device is less than the first threshold distance provides feedback to a user of the computer system indicating that the distance between the computer system and the first external device is less than the first threshold distance. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the status information includes an indication of whether media is being played back at the first external device, an indication of what media is being played back at the first external device, an indication of a type of media (e.g., call, music, podcast, voice command, virtual assistant) being played back at the first external device, and/or an indication of whether the first external device is turned on/off, connected/disconnected, and/or has sufficient power. 
     In some embodiments, the computer system (e.g.,  600 ) displays the second status information (e.g.,  612 - 2 ;  612 - 1 ) associated with the first external device (e.g.,  605 ), including displaying a second representation (e.g.,  615 ) (e.g., an affordance (selectable graphical user interface object) representing a “pill” view) of the media control user interface transitioning (e.g., see  FIGS.  6 G- 6 I ) from a first state (e.g.,  615  in  FIG.  6 G ) that does not include the second status information (e.g., the “pill” view) to a second state (e.g.,  612 ′ in  FIG.  6 H ;  612  in  FIG.  6 I ) that includes the second status information (e.g., the second state of the second representation of the media control user interface is the media control user interface). Displaying a second representation of the media control user interface transitioning from a first state that does not include the second status information to a second state that includes the second status information provides feedback to a user of the computer system indicating that the distance between the computer system and the first external device is less than the first threshold distance. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the second representation of the media control user interface includes little or no status information in the first state, and includes the second status information in the second state. 
     In some embodiments, in response to receiving the input (e.g.,  632 ), and in accordance with a determination that the input corresponds to a predefined gesture (e.g., an upward swipe that originates at a location on the media control user interface), the computer system (e.g.,  600 ) ceases display of the one or more selectable user interface objects (e.g.,  612 - 1 ) for controlling the playback of the second media on the first external device (e.g.,  605 ) (e.g., see  FIGS.  6 U- 6 W ). In some embodiments, ceasing display of the one or more selectable user interface objects for controlling the playback of the second media on the first external device includes displaying an animation of the media control user interface shrinking to a representation (e.g., an affordance showing a “pill” view) of the media control user interface (e.g., see  FIG.  6 V ). 
     Note that details of the processes described above with respect to method  800  (e.g.,  FIG.  8   ) are also applicable in an analogous manner to the methods described above and below. For example, methods  700 ,  1000 , and  1200  optionally include one or more of the characteristics of the various methods described above with reference to method  800 . For example, these methods can include displaying a controls interface, as discussed in method  800 . For brevity, these details are not repeated below. 
       FIGS.  9 A- 9 R  illustrate exemplary embodiments for managing media playback devices, in accordance with some embodiments. The embodiments in these figures are used to illustrate the processes described below, including the processes in  FIG.  10   . 
       FIGS.  9 A- 9 R  depict various examples in which device  900  performs one or more operations in response to inputs that are received at device  900  when device  900  is in various operational states. Device  900  is similar to device  580  and device  605  (e.g., includes one or more features of devices  580  and  605 ), and includes touch-sensitive surface  901  (similar to touch-sensitive surface  580 D), one or more displays  902  (similar to display  580 E), one or more speakers  903  (similar to speakers  580 B concealed in body  580 A), and one or more microphones  904  (similar to microphone(s)  580 C). In the embodiments illustrated in  FIGS.  9 A- 9 R , display  902  is generally distinguished from touch-sensitive surface  901  by the depiction of light (e.g., light  905 ). However, because the display may not be activated in all figures or, when activated, the light can vary in displayed size (as well as other characteristics such as brightness, intensity, color, pattern, movement, etc.), reference number  902  should be understood to refer generally to the display component of device  900 . 
     In  FIGS.  9 A- 9 R , touch-sensitive surface  901  includes first portion  901 - 1 , second portion  901 - 2 , and third portion  901 - 3 . The dashed lines separating the first, second, and third portions are for illustrative purposes only and are not part of device  900 . Second portion  901 - 2  includes feature  901 A, and third portion  901 - 3  includes feature  901 B. In some embodiments, features  901 A and  901 B are physical markings such as ridges or etchings that distinguish the second and third portions from the first portion. Each respective portion corresponds to one or more operations that can be performed at device  900  in response to an input at the respective portion. In some embodiments, the operation(s) that is associated with a respective portion depends on the state of device  900 , as discussed in greater detail below. Thus, as the state of device  900  changes, the operation(s) associated with the respective portion can also change. 
     In some embodiments, the state of device  900  is indicated by one or more characteristics of light  905  such as, for example, the color, size, and/or brightness of light  905 , as discussed in greater detail below.  FIGS.  9 A- 9 R , and the corresponding description of those figures, demonstrate various non-limiting examples of the states of device  900 , operations device  900  performs during these states, and various combinations of the characteristics of light  905  displayed by device  900  during these states and operations. The examples in  FIGS.  9 A- 9 R  are for illustrative purposes, and are not intended to limit the states, operations, and light characteristics that can be performed by device  900 . Thus, additional combinations of states, operations, and light characteristics can be performed by device  900 , as understood from the examples provided herein. 
     In some embodiments, the state of device  900  is indicated by the displayed size of light  905 . Examples of such embodiments are discussed in greater detail with respect to  FIGS.  11 A- 11 R . 
     In some embodiments, the state of device  900  is indicated by the color of light  905 . For example, device  900  displays light having a green color when device  900  is in a communication state, having a multi-color pattern when device  900  is in a virtual assistant state, having a white color (or a color that corresponds to a particular song or album) when device  900  is in a music playback state, having an amber color when device  900  is in a low power state (e.g., device  900  has a low power supply), or having a red color when device  900  needs to be reset. In the embodiments depicted in  FIGS.  9 A- 9 R , different colors of light  905  are represented by different hatch patterns. 
     In some embodiments, the state of device  900  is indicated by the brightness of light  905  or a temporary change in brightness. For example, device  900  displays light  905  having a dim state when music is paused, and displays light  905  having a brighter state when music is playing. As another example, device  900  temporarily brightens light  905  to indicate an input is received at device  900 , and dims light  905  when an input has not been received at device  900  for a predetermined amount of time. In some embodiments, device  900  brightens or dims light  905  in response to volume adjustments (e.g., increase brightness with a volume increase and decrease brightness with a volume decrease). In some embodiments, the brightness of light  905  is represented by the shade of light  905  depicted in the figures. For example, darker shades of light  905  can represent brighter display of light, and lighter shades of light  905  can represent dimmer display of light. 
     In some embodiments, the operation(s) that is performed at device  900  in response to an input depends on various characteristics of the input such as, for example, a size, location, and/or duration of the input. For example, in some embodiments, a respective portion of touch-sensitive surface  901  can be associated with two operations that can be performed in response to an input at the respective portion, and device  900  performs a first operation when the input has a first set of characteristics and performs a second operation when the input has a second set of characteristics. 
       FIGS.  9 A- 9 N  depict various embodiments in which device  900  performs different operations based on a size, location, and duration of the input, when the device is generally in a state for playing music.  FIGS.  9 A- 9 F  depict various operations performed by device  900  when the input is a small touch gesture such as, for example, a tap gesture or a touch-and-hold gesture having contact with touch-sensitive surface  901  that is smaller than a predetermined size threshold.  FIGS.  9 G- 9 N  depict various operations performed by device  900  when the input is a large touch gesture such as, for example, a tap gesture or a touch-and-hold gesture having a contact with touch-sensitive surface  901  that is larger than a predetermined size threshold. 
     In  FIG.  9 A , device  900  is currently playing music at volume of 5, as depicted by light  905 , indicator  910 , and indicator  915 . In the embodiment depicted in  FIG.  9 A , device  900  displays light  905  (e.g., similar to light  607 ) when device  900  is in the state for playing music. In some embodiments, the color of light  905  varies depending on the audio being output at device  900 . For example, in some embodiments, when the audio is music, the light is a white hue or has a color that corresponds to the music that device  900  is playing. In the embodiment depicted in  FIG.  9 A , light  905  has a purple hue that corresponds to the music playing at device  900 , as discussed above with respect to the embodiments in  FIGS.  6 A- 6 X . 
     In  FIG.  9 B , device  900  detects input  912  at portion  901 - 1  while device  900  is playing music. In response, device  900  performs different operations depending on the characteristics of the input. For example, if input  912  is a small, long-touch input (e.g., the input is a touch input that is smaller than a predetermined size threshold and is held for at least a predetermined amount of time), device  900  activates a virtual assistant, as shown in  FIG.  9 C . In this embodiment, device  900  transitions to a state in which a virtual assistant is activated—that is, device  900  is configured to interact with a user by facilitating interaction with a virtual assistant (e.g., artificial intelligence) using various components of device  900 . Accordingly, device  900  pauses the music (as depicted by indicator  911 ), activates microphone  904  (as depicted by indicator  913 ), and displays light  905  having a larger size and different color than in  FIG.  9 B , indicating that the state of device  900  has changed from the music playback state in  FIG.  9 B  to the virtual assistant state in  FIG.  9 C . As shown in  FIG.  9 C , light  905  has a multi-color pattern to represent the virtual assistant state. 
     In some embodiments, the operations associated with portions  901 - 1 ,  901 - 2 , and  901 - 3  change when device  900  transitions from the music playback state to the virtual assistant state. For example, during the music playback state, portions  901 - 2  and  901 - 3  correspond to volume adjustment operations (e.g., volume up and volume down, respectively), and portion  901 - 1  corresponds to an operation for enabling the virtual assistant and an operation for pausing the music (as discussed in greater detail below). However, during the virtual assistant state, portions  901 - 1 ,  901 - 2 , and  901 - 3  each correspond to an operation for terminating the virtual assistant. In other words, if device  900  detects an input on any of portions  901 - 1 ,  901 - 2 , and  901 - 3 , while in the virtual assistant state shown in  FIG.  9 C , device  900  will cancel the virtual assistant and transition back to the music playback state depicted in  FIG.  9 B . 
     Referring again to  FIG.  9 B , if input  912  is a small, tap input (e.g., the input is a touch input that is smaller than the predetermined size threshold and is not held for at least the predetermined amount of time), device  900  remains in the music playback state and pauses playback of the music, as shown in  FIG.  9 D . In this embodiment, device  900  pauses the music (as depicted by indicator  911 ) and changes light  905  to a small, white light as shown in  FIG.  9 D  to indicate the music has been paused. 
     In  FIG.  9 D , device  900  detects input  914  (e.g., a small, tap input) on portion  901 - 1  (slightly overlapping portion  901 - 2 ) and, in response, resumes playback of the music, as shown in  FIG.  9 E . In the embodiment depicted in  FIG.  9 D , although input  914  slightly overlaps portion  901 - 2 , device  900  determines the input to be on portion  901 - 1  because, for example, the majority of the surface area of input  914  is on portion  901 - 1 . 
     In  FIG.  9 E , device  900  is playing music at a volume of 5 and detects input  916  (e.g., a small, tap input) on portion  901 - 2 . In response, device  900  increases the volume of the music from a volume of 5 to a volume of 6, as indicated by volume indicator  915  in  FIGS.  9 E and  9 F . 
     In  FIG.  9 F , device  900  is playing music at a volume of 6 and detects input  918  (e.g., a small, tap input) on portion  901 - 3 . In response, device  900  decreases the volume of the music from a volume of 6 to a volume of 5, as indicated by volume indicator  915  in  FIGS.  9 F and  9 G . Again, in the embodiment depicted in  FIG.  9 F , device  900  determines input  918  is on portion  901 - 3  because a majority of the contact area from input  918  is on portion  901 - 3 . 
       FIGS.  9 G- 9 N  depict various operations performed by device  900  when the input is a large touch gesture located on touch-sensitive surface  901 . 
     In  FIG.  9 G , device  900  is playing music at a volume of 5 and detects input  920 . Input  920  is a large, tap input, such as a touch input from a palm or other large portion of user&#39;s hand  921 , that is maintained for less than a predetermined amount of time. Although hand  921  is depicted extending beyond the edges of device  900 , input  920  is caused by contact of hand  921  with touch-sensitive surface  901 . In  FIG.  9 G , input  920  is located primarily on portion  901 - 2  of touch-sensitive surface  901  and, therefore, device  900  determines input  920  is located at portion  901 - 2 . Importantly, because input  920  is a large, tap input (e.g., the tap input is larger than a predetermined size threshold and is maintained for less than a predetermined amount of time), device  900  performs a different operation than when the input is a small touch input. Specifically, rather than performing the volume adjustment operation that is performed when the input is a small, tap input at portion  901 - 2 , device  900  pauses the music, which, in the current embodiment, is the same operation performed by device  900  when the input is a small, tap input at portion  901 - 1 . 
     As depicted in  FIG.  9 H , device  900  pauses the music in response to input  920 , as depicted by indicator  911  and light  905 . While the music is paused, device  900  detects input  922 , which is a large, tap input on portion  901 - 1 , and partially overlapping portion  901 - 3 . In response, device  900  resumes playing music, as illustrated in  FIG.  9 I . 
     In  FIG.  9 I , device  900  detects input  924  (large, tap input) on portion  901 - 3  while music is playing. In response, device  900  pauses the music, as depicted in  FIG.  9 J . 
     In  FIG.  9 J , while the music is paused, device  900  detects input  926  (large, tap input) on portion  901 - 1  and, in response, resumes playing the music, as shown in  FIG.  9 K . 
       FIGS.  9 G- 9 K  demonstrate that, when the input on touch-sensitive surface  901  is a large, tap input, device  900  performs the operation that is performed when the input is a small, tap input at portion  901 - 1 , regardless of where the large, tap input is located (detected) on touch-sensitive surface  901 . In the embodiments depicted in  FIGS.  9 A,  9 B, and  9 D- 9 K , this operation is a play/pause operation. However, other operations can be performed, depending on the state of device  900 . For example, the operation can be a cancel operation when device  900  is performing a timer function, performing an alarm function, engaged in a communication session, playing a recorded message, or (as depicted in  FIG.  9 C ) performing a virtual assistant function. 
       FIGS.  9 L- 9 R  depict various operations that are performed by device  900  when the input is a large touch-and-hold gesture—that is, a touch input (e.g., from a palm or other large portion of user&#39;s hand  921 ) that is larger than a predetermined size threshold and is maintained for more than a predetermined amount of time on touch-sensitive surface  901 . In some embodiments, the large touch-and-hold gesture is referred to as a cover gesture, because the user is covering the touch-sensitive surface  901  with their hand  921 . 
     In  FIG.  9 L , device  900  is playing music at a volume of 5 and detects input  928 , which is a large touch-and-hold gesture on touch-sensitive surface  901 . When device  900  detects input  928  is maintained on touch-sensitive surface  901  for a predetermined amount of time, device  900  lowers the output volume of the music (e.g., to a volume of 1), as depicted in  FIG.  9 M . Device  900  continues to play music at the lowered volume for as long as input  928  is maintained. When input  928  is no longer detected, device  900  increases the volume of the music back to the previous volume of 5, as depicted in  FIG.  9 N . 
       FIGS.  9 O- 9 R  depict an embodiment in which device  900  performs an operation in response to a large touch-and-hold gesture when device  900  is in a communication state. In the communication state, device  900  is outputting communication audio for a communication session (e.g., a phone call, video chat), as depicted by indicator  930 , and microphone  904  is receiving audio for the communication session, as depicted by indicator  932 . Additionally, light  905  has a green hue, indicating device  900  is in a communication state. 
     In  FIG.  9 P , device  900  detects input  934 , which is a large touch-and-hold gesture on touch-sensitive surface  901 . When device  900  detects input  934  is maintained on touch-sensitive surface  901  for a predetermined amount of time, device  900  mutes the audio received for the communication session, as depicted by indicator  932  in  FIG.  9 Q , while continuing to output the communication session audio. Device  900  continues to mute the audio received for the communication session for as long as input  934  is maintained. When input  934  is no longer detected, device  900  unmutes the audio received for the communication session, as depicted by indicator  932  in  FIG.  9 R . In some embodiments, the audio for the communication session can be muted in such a way that microphone  904  remains activated. For example, the audio received at microphone  904  is used for a task other than the communication session. For example, audio received at microphone  904  can be used for interacting with a virtual assistant instead of the communication session. 
       FIG.  10    is a flow diagram illustrating a method for managing media playback devices using an electronic device in accordance with some embodiments. Method  1000  is performed at a device (e.g.,  100 ,  300 ,  500 ,  900 ) with a touch-sensitive surface (e.g.,  901 ). Some operations in method  1000  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     In some embodiments, the electronic device (e.g.,  900 ) is a computer system (e.g., a speaker; a digital media player). The computer system is optionally in communication (e.g., wired communication, wireless communication) with a touch-sensitive surface (e.g.,  901 ) (e.g., a touch-sensitive display). The touch-sensitive surface includes a first portion (e.g.,  901 - 1 ) that is associated with a first operation (e.g., a playback control operation; pause; play; mute; unmute) and a second portion (e.g.,  901 - 2 ) that is associated with (e.g., primarily associated with; by default) a second operation (e.g., a volume increase operation; a volume decrease operation), different from the first operation (e.g., the second portion is separate (e.g., physically distanced) from the first portion). In some embodiments the computer system includes a display generation component (e.g.,  902 ) (e.g., a display controller, a touch-sensitive display system). The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. 
     As described below, method  1000  provides an intuitive way for managing media playback devices. The method reduces the cognitive burden on a user for managing media playback devices, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage media playback devices faster and more efficiently conserves power and increases the time between battery charges. 
     In method  1000 , the computer system (e.g.,  900 ) detects ( 1002 ), via the touch-sensitive surface (e.g.,  901 ), a first input (e.g., a touch input) (e.g.,  912 ;  914 ;  916 ;  918 ;  920 ;  922 ;  924 ;  926 ;  928 ;  934 ). Detecting the first input includes detecting first contact having a respective size (e.g., surface area; contiguous surface area; total contacted surface area). 
     In response ( 1004 ) to detecting the first input (e.g.,  912 ;  914 ;  916 ;  918 ;  920 ;  922 ;  924 ;  926 ;  928 ;  934 ), the computer system (e.g.,  900 ) performs steps  1006 ,  1008 , and  1010  of method  1000 . 
     In accordance with a determination that the respective size of the first contact is less than a first threshold size (e.g., a size of contact shown in  FIGS.  9 A- 9 F ) (e.g., the amount of area of the touch-sensitive surface occupied by the first contact is less than a first threshold amount of area (e.g., a non-zero amount of surface area; an amount of surface area less than the area of the first portion) of the touch-sensitive surface (e.g., the touch input includes contact with less than a predefined amount of the touch surface) (e.g., the first input is a touch that is smaller than a predefined size)) and that the first input (e.g.,  912 ;  914 ) is directed to the first portion (e.g.,  901 - 1 ) of the touch-sensitive surface (e.g., at least a predefined amount (e.g., 51%, 55%, 60%) of the touch contact is located within the first portion; the entirety of the first input is within the first portion), the computer system (e.g.,  900 ) initiates ( 1006 ) a process for performing the first operation. 
     In accordance with a determination that the respective size of the first contact is less than the first threshold size (e.g., a size of contact shown in  FIGS.  9 A- 9 F ) and that the first input (e.g.,  916 ;  918 ) is directed to the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive surface (e.g., at least a predefined amount (e.g., 51%, 55%, 60%) of the touch contact is located on the second portion; the entirety of the first input is within the second portion), the computer system (e.g.,  900 ) initiates ( 1008 ) a process for performing the second operation. 
     In accordance with a determination that the respective size of the first contact is greater than the first threshold size (e.g., a size of contact shown in  FIGS.  9 G- 9 Q ), the computer system (e.g.,  900 ) initiates ( 1010 ) a process for performing the first operation (e.g., without performing the second operation) without regard for whether the first input is directed to the first portion or the second portion of the touch-sensitive surface. Initiating a process for performing the first operation or the second operation based on whether the first input is directed to the first or second portion of the touch-sensitive surface when the respective size of the first contact is less than the first threshold size, and initiating a process for performing the first operation without regard for whether the input is directed to the first or second portion when the respective size of the first contact is greater than the first threshold size, provides a technique for disambiguating inputs in a manner that reduces the risk of performing unintended actions, thereby reducing the number of inputs at the computer system and conserving computational resources. Reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, initiating the process for performing the first operation without regard for whether the first input is directed to the first portion (e.g.,  901 - 1 ) or the second portion (e.g.,  901 - 2 ;  901 - 3 ) includes: in accordance with a determination that the first input (e.g.,  922 ;  926 ) is directed to the first portion (e.g.,  901 - 1 ), the computer system (e.g.,  900 ) performs the first operation; and in accordance with a determination that the first input (e.g.,  920 ;  924 ) is directed to the second portion (e.g.,  901 - 2 ;  901 - 3 ), the computer system performs the first operation. In some embodiments, initiating the process for performing the first operation without regard for whether the first input is directed to the first portion or the second portion includes: the computer system detects a second input (e.g.,  922 ;  926 ) directed to the first portion of the touch-sensitive surface and, in response to the second input, initiates a process for performing the first operation; and the computer system detects a third input (e.g.,  920 ;  924 ) directed to the second portion of the touch-sensitive surface and, in response to the third input, the computer system initiates a process for performing the first operation (e.g., without initiating a process for performing the second operation). 
     In some embodiments, in response to detecting the first input (e.g.,  912 ;  914 ;  916 ;  918 ;  920 ;  922 ;  924 ;  926 ;  928 ;  934 ), in accordance with a determination that the respective size of the first contact is greater than the first threshold size (e.g., a size of contact shown in  FIGS.  9 G- 9 Q ) and that the first input (e.g., the first contact of the first input) (e.g.,  920 ;  922 ;  924 ) is detected on at least a subset (e.g., a portion) of the first portion (e.g.,  901 - 1 ) of the touch-sensitive surface and at least a subset of the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive surface, the computer system (e.g.,  900 ) initiates a process for performing the first operation (e.g., without performing the second operation). Initiating a process for performing the first operation when the respective size of the first contact is greater than the first threshold size and the first input is detected on at least a subset of the first portion of the touch-sensitive surface and at least a subset of the second portion of the touch-sensitive surface, provides a technique for disambiguating inputs in a manner that reduces the risk of performing unintended actions, thereby reducing the number of inputs at the computer system and conserving computational resources. Reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, in response to detecting the first input (e.g.,  914 ;  918 ), in accordance with a determination that the respective size of the first contact is less than the first threshold size (e.g., a size of contact shown in  FIGS.  9 A- 9 F ) and that the first contact is detected on at least a subset of the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive surface, the computer system (e.g.,  900 ) initiates a process for performing the first operation or the second operation based on a position of the first contact on the touch-sensitive surface (e.g., based on where a representative portion such as a center portion or edge portion of the first contact is located; based on where a majority of the first contact is located). In accordance with a determination that the position of the first contact meets a first set of position criteria (e.g., a representative portion (e.g., a center portion, an edge portion) of the first contact is located on the first portion of the touch-sensitive surface; at least a predefined amount (e.g., 25%, 35%, 45%, 51%, 55%, 60%, 75%, 85%, 95%, 99%, 100%, more than 50%) of the first contact is located on the first portion), the computer system initiates a process for performing the first operation (e.g., see input  914  in  FIG.  9 D ). In accordance with a determination that the position of the first contact meets a second set of position criteria (e.g., a representative portion (e.g., a center portion, an edge portion) of the first contact is located on the second portion of the touch-sensitive surface; at least a predefined amount (e.g., 25%, 35%, 45%, 51%, 55%, 60%, 75%, 85%, 95%, 99%, 100%, more than 50%) of the first contact is located on the second portion), different from the first set of position criteria, the computer system initiates a process for performing the second operation (e.g., see input  918  in  FIG.  9 F ). Initiating a process for performing the first operation or the second operation based on a position of the first contact when the respective size of the first contact is less than the first threshold size and the first contact is detected on at least a subset of the second portion of the touch-sensitive surface provides a technique for disambiguating inputs in a manner that reduces the risk of performing unintended actions, thereby reducing the number of inputs at the computer system and conserving computational resources. Reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the first portion (e.g.,  901 - 1 ) of the touch-sensitive surface includes a central portion (e.g., a center region; a region located at a midpoint of a diameter of the touch-sensitive surface) of the touch-sensitive surface (e.g.,  901 ). 
     In some embodiments, the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive surface includes an edge portion (e.g., one or more outer portions; one or more regions positioned at an edge of the touch-sensitive surface) of the touch-sensitive surface (e.g.,  901 ). In some embodiments, the first portion is an hourglass-shaped region and the second portion includes one or more parabolic-shaped regions located adjacent a midpoint of the first portion. 
     In some embodiments, the computer system (e.g.,  900 ) initiates a process for performing the first operation, including: in accordance with a determination that the computer system is currently causing output of first audio (e.g., playing music) (e.g., see  FIG.  9 B ), the computer system ceases output of the first audio (e.g., pausing the first audio) (e.g., see  FIG.  9 D ); and in accordance with a determination that the computer system is not currently causing output of first audio (e.g., see  FIG.  9 D ), the computer system initiates output of the first audio (e.g., playing/initiating playback of/resuming the first audio) (e.g., see  FIG.  9 E ). 
     In some embodiments, the computer system (e.g.,  900 ) is currently causing output of second audio (e.g., at a first volume) (e.g., see  FIG.  9 E ), and the second operation includes adjusting a volume of the second audio (e.g., increasing or decreasing the second audio to a second volume different than the first volume) (e.g., see  FIGS.  9 F and  9 G ). 
     In some embodiments, the touch-sensitive surface (e.g.,  901 ) includes a third portion (e.g.,  901 - 3 ) (e.g., separate from the first and second portion, physically and/or visually distinguished from the first and second portion) that is associated with a third operation (e.g., a volume increase; a volume decrease) that is different from the first operation and the second operation. In some embodiments, the second operation is a first type of volume adjustment (e.g., a volume increase operation), and the third operation is a second type of volume adjustment (e.g., a volume decrease operation). 
     In some embodiments, the computer system (e.g.,  900 ) detects, via the touch-sensitive surface (e.g.,  901 ), a second input (e.g., the first input) (e.g.,  928 ;  934 ), wherein detecting the second input includes detecting second contact (e.g., the first contact of the first input) having a second respective size (e.g., a size of contact shown in  FIGS.  9 L,  9 M,  9 P , and/or  9 Q) (e.g., the second input is a hand-cover gesture (e.g., a placement of a hand over a predetermined amount (e.g., 15%, 25%, 35%, 45%, 55%, 65% 75%, 80%, 85%, 90% 95%, 100%) of the touch-sensitive surface)). In response to detecting the second input, in accordance with a determination that the second respective size of the second contact is greater than a second threshold size (e.g., a size of contact shown in  FIGS.  9 L,  9 M,  9 P , and/or  9 Q) (e.g., the first threshold size; a threshold size greater than the first threshold size), the computer system initiates a process for performing a fourth operation (e.g., the first operation; a different operation; a mute operation; a volume reduction operation). The process for performing the fourth operation includes in accordance with a determination that a first set of criteria is met, wherein the first set of criteria includes a first criterion that is met while the second contact is detected having the second respective size greater than the second threshold size (e.g., see  FIG.  9 M  and/or  FIG.  9 Q ) (e.g., while the user&#39;s hand is detected covering the touch-sensitive surface), performing the fourth operation (e.g., the fourth operation is maintained for as long as the second contact is detected having the second respective size greater than the second threshold size). The process for performing the fourth operation includes in accordance with a determination that the first set of criteria is no longer met (e.g., the second contact is no longer detected, or is no longer detected having the second respective size greater than the second threshold), ceasing to perform the fourth operation (e.g., see  FIG.  9 N  and/or  FIG.  9 R ). Performing the fourth operation while the second contact is detected having the second respective size greater than the second threshold size, and ceasing to perform the fourth operation when the second contact is no longer detected having the second respective size greater than the second threshold size, provides a technique for disambiguating inputs in a manner that reduces the number of inputs required for selectively performing the fourth operation for a desired amount of time, which also reduces the risk of performing unintended actions, thereby further reducing the number of inputs at the computer system and conserving computational resources. Reducing the number of inputs at the computer system enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  900 ) is in communication with an audio input device (e.g.,  904 ) (e.g., a microphone). In some embodiments, the first set of criteria further includes a second criterion that is met when the computer system is engaged in (e.g., participating in, hosting) a communication session (e.g., a video communication session; a phone call) (e.g., see  FIGS.  9 O- 9 R ). In some embodiments, performing the fourth operation includes muting audio input captured by (e.g., temporarily disabling; muting) the audio input device for the communication session (e.g., see  FIG.  9 Q ) (e.g., the computer system mutes audio input detected at the microphone for the communication session for as long as the second contact is detected having the second respective size greater than the second threshold size). In some embodiments, the microphone is not disabled or muted, but rather, is using the audio input for purposes other than the communication session. For example, the audio detected at the microphone is used for providing instruction to a virtual assistant, rather than being used as audio input for the communication session. 
     In some embodiments, the first set of criteria further includes a third criterion that is met when the computer system (e.g.,  900 ) is causing output of third audio (e.g., playing music) (e.g., see  FIG.  9 L ). In some embodiments, performing the fourth operation includes reducing an output volume of the third audio from a first volume to a second volume (e.g., a non-zero volume setting; a reduced volume) different from the first volume (e.g., see  FIG.  9 M ) (e.g., reducing the output volume for as long as the second contact is detected having the second respective size greater than the second threshold size). In some embodiments, ceasing performance of the fourth operation includes increasing the output volume of the second audio from the second volume to a third volume (e.g., see  FIG.  9 N ) (e.g., the first volume) (e.g., when the hand-cover gesture is no longer detected, the volume is no longer reduced). 
     In some embodiments, the first operation is determined based on a state of the computer system (e.g.,  900 ). In some embodiments, in accordance with a determination that the computer system has a first state in which the computer system is causing output of fourth audio (e.g., see  FIG.  9 L ) (e.g., output of music), the computer system initiates a process for performing the first operation, including temporarily causing output of the fourth audio at a decreased output volume (e.g., see  FIG.  9 M ) (e.g., temporarily generating the fourth audio at a reduced volume (e.g., for as long as the first input is detected)). In some embodiments, in accordance with a determination that the computer system has a second state in which the computer system is engaged in (e.g., participating in, hosting) a communication session (e.g., see  FIG.  9 P ) (e.g., a video communication session; a phone call), the computer system initiates a process for performing the first operation, including temporarily muting audio input captured by an audio input device for the communication session (e.g., see  FIG.  9 Q ) (e.g., a microphone that is in communication with the computer system). 
     Note that details of the processes described above with respect to method  1000  (e.g.,  FIG.  10   ) are also applicable in an analogous manner to the methods described below. For example, methods  700 ,  800 , and  1200  optionally include one or more of the characteristics of the various methods described above with reference to method  1000 . For example, these methods can include performing operations based on various characteristics of an input, including a size of contact, as discussed in method  1000 . For brevity, these details are not repeated below. 
       FIGS.  11 A- 11 R  illustrate exemplary embodiments for managing media playback devices, in accordance with some embodiments. The embodiments in these figures are used to illustrate the processes described below, including the processes in  FIGS.  12 A and  12 B . 
       FIGS.  11 A- 11 R  depict various examples in which device  900  performs one or more operations in response to inputs that are received at device  900  when device  900  is in various operational states, as indicated by various characteristics of light  905  displayed at device  900 . In the embodiments illustrated in  FIGS.  11 A- 11 R , display  902  is generally distinguished from touch-sensitive surface  901  by the depiction of light (e.g., light  905 ). However, because the display may not be activated in all figures or, when activated, the light can vary in displayed size (as well as other characteristics such as brightness, intensity, color, pattern, movement, etc.), reference number  902  should be understood to refer generally to the display component of device  900 . 
     In  FIGS.  11 A- 11 R , touch-sensitive surface  901  includes first portion  901 - 1 , second portion  901 - 2 , and third portion  901 - 3 . Second portion  901 - 2  includes feature  901 A, and third portion  901 - 3  includes feature  901 B. In some embodiments, features  901 A and  901 B are physical markings such as ridges or etchings that distinguish the second and third portions from the first portion (this is because the dashed lines separating the first, second, and third portions are for illustrative purposes only and are not part of device  900 ). Each respective portion corresponds to one or more operations that can be performed at device  900  in response to an input at the respective portion. In some embodiments, the operation(s) that is associated with a respective portion depends on the state of device  900 , as discussed in greater detail below. Thus, as the state of device  900  changes, the operation(s) associated with the respective portion can also change. 
     In some embodiments, the state of device  900  is indicated by one or more characteristics of light  905  such as, for example, the color, size, and/or brightness of light  905 , as discussed in greater detail below.  FIGS.  11 A- 11 R , and the corresponding description of those figures, demonstrate various non-limiting examples of the states of device  900 , operations device  900  performs during these states, and various combinations of the characteristics of light  905  displayed by device  900  during these states and operations. The examples in  FIGS.  11 A- 11 R  are for illustrative purposes, and are not intended to limit the states, operations, and light characteristics that can be performed by device  900 . Thus, additional combinations of states, operations, and light characteristics can be performed by device  900 , as understood from the examples provided herein. 
     In some embodiments, the state of device  900  is indicated by the displayed size of light  905 . For example, light  905  is a small size (e.g., less than a predetermined size threshold) when device  900  is in a first state, and light  905  is a large size (e.g., greater than the predetermined size threshold) when device  900  is in a second (different) state. Accordingly, portions  901 - 1 ,  901 - 2 , and  901 - 3  have a first set of operations associated with the portions during the first state and a second set of operations associated with the portions during the second state. In some embodiments, device  900  is in the first state, and displays light  905  having a small size, when device  900  is playing music or audio for communication sessions such as a phone call, a video call, or an incoming audio message. In some embodiments, device  900  is in the second state, and displays light  905  having a large size, when device  900  is in a virtual assistant state (discussed above), performing a timer or alarm operation, recording an outgoing audio message, or, in some embodiments, when audio playback is transitioning to (or from) device  900 , as discussed above with respect to  FIGS.  6 A- 6 X . 
     In some embodiments, the state of device  900  is indicated by the color of light  905 . For example, device  900  displays light having a green color when device  900  is in a communication state, having a multi-color pattern when device  900  is in a virtual assistant state, having a white color (or a color that corresponds to a particular song or album) when device  900  is in a music playback state, having an amber color when device  900  is in a low power state (e.g., device  900  has a low power supply), or having a red color when device  900  needs to be reset. In the embodiments depicted in  FIGS.  11 A- 11 R , different colors of light  905  are represented by different hatch patterns. 
     In some embodiments, the state of device  900  is indicated by the brightness of light  905  or a temporary change in brightness. For example, device  900  displays light  905  having a dim state when music is paused, and displays light  905  having a brighter state when music is playing. As another example, device  900  temporarily brightens light  905  to indicate an input is received at device  900 , and dims light  905  when an input has not been received at device  900  for a predetermined amount of time. In some embodiments, device  900  brightens or dims light  905  in response to volume adjustments (e.g., increase brightness with a volume increase and decrease brightness with a volume decrease). In some embodiments, the brightness of light  905  is represented by the shade of light  905  depicted in the figures. For example, darker shades of light  905  can represent brighter display of light, and lighter shades of light  905  can represent dimmer display of light. 
     In some embodiments, the operation(s) that is performed at device  900  in response to an input depends on various characteristics of the input such as, for example, a size, location, and/or duration of the input. For example, in some embodiments, a respective portion of touch-sensitive surface  901  can be associated with two operations that can be performed in response to an input at the respective portion, and device  900  performs a first operation when the input has a first set of characteristics and performs a second operation when the input has a second set of characteristics. 
       FIGS.  11 A- 11 H  illustrate embodiments in which various operations are associated with portions  901 - 1 ,  901 - 2 , and  901 - 3  when device  900  is in a first state. Because device  900  is in the first state, device  900  displays light  905  having a small size, to indicate that distinct operations can be performed at each of portions  901 - 1 ,  901 - 2 , and  901 - 3 . 
     In  FIG.  11 A , device  900  is currently in a music playback state in which the music is paused (as depicted by indicator  1110 ), and the volume setting is 5 (as depicted by indicator  1115 ). In the embodiment depicted in  FIG.  11 A , device  900  displays light  905  (e.g., similar to light  607  and light  905 ) when device  900  is in the state for playing music. In some embodiments, the color of light  905  varies depending on the audio being output at device  900 . For example, in some embodiments, when the audio is music, the light is a white hue or has a color that corresponds to the music that device  900  is playing. In the embodiment depicted in  FIG.  11 A , light  905  has a dim white hue. The white color indicates that the audio is music, and the dimmed brightness indicates that the music is paused. In some embodiments, device  900  does not display light  905  when the music is paused. 
     In  FIG.  11 A , device  900  detects input  1112  (e.g., a small, tap input) on first portion  901 - 1 . In response, device  900  pulses light  905  (e.g., to indicate receipt of the input) and resumes playback of the music at a volume of 5, as depicted by indicators  1110  and  1115 , as shown in  FIG.  11 B . The pulse of light  905  is depicted in  FIG.  11 B  (and similar figures) by outer portion  905 - 1  of light  905  and inner portion  905 - 2  of light  905 , which represent a temporary increase in the size and, optionally, brightness of light  905 . The increased size is depicted by the larger displayed region of light  905 . The increased brightness is depicted by the darker shading of inner portion  905 - 2 . Outer portion  905 - 1  has the same shade as light  905  in  FIG.  11 A , and inner portion  905 - 2  is depicted with a darker shade than outer portion  905 - 1 , indicating that the inner portion of light  905  is brighter than outer portion  905 - 1  (and light  905  in  FIG.  11 A ). In some embodiments, device  900  blinks light  905  in addition to, or in lieu of, the pulsing light  905 . 
     In  FIG.  11 C , device  900  is playing music at a volume of 5 and displays light  905  having a brighter, larger appearance than in  FIG.  11 A  to indicate music is playing. In some embodiments, device  900  displays light  905  having an animated appearance that moves, flickers, pulses, changes colors, or the like in concert with the beat of the music. In some embodiments, device  900  displays light  905  having a color that represents the music. As shown in  FIG.  11 C , device  900  detects input  1114  (e.g., a small, tap input) on portion  901 - 2 . In response, device  900  pulses light  905  and increases the volume from level 5 to level 6, as depicted in  FIG.  11 D . 
     In  FIG.  11 E , device  900  is playing music at a volume of 6 and detects input  1116  (e.g., a small, tap input) on portion  901 - 3 . In response, device  900  pulses light  905  and decreases the volume from level 6 to level 5, as depicted in  FIG.  11 F . 
     In  FIG.  11 G , device  900  is playing music at volume 5 and detects input  1118  (e.g., a small, tap input) on portion  901 - 1 . In response, device  900  pauses the music, as depicted by indicator  1110 , and shrinks light  905  to a dim, white color to represent the paused state, as depicted in  FIG.  11 H . 
     In the embodiments depicted in  FIGS.  11 A- 11 H , device  900  increases or decreases the volume in response to an input (e.g., input  1114  or input  1116 ) at second portion  901 - 2  or third portion  901 - 3 , and pauses or plays music in response to an input (e.g., input  1112  or input  1118 ) at portion  901 - 1 , when device  900  is in a music playback state. In some embodiments, however, device  900  can perform different operations in response to inputs detected at portion  901 - 1 . For example, in some embodiments, device  900  can initiate or cancel a task in response to detecting an input at portion  901 - 1 . For example, in response to detecting an input at portion  901 - 1 , device  900  can initiate or cancel a virtual assistant operation, initiate or cancel a timer operation, initiate or cancel an alarm operation, or initiate or cancel a communication session. An embodiment is depicted in  FIGS.  11 I and  11 J , where device  900  is in a communication state, and input at portion  901 - 1  terminates the communication session. 
     In  FIG.  11 I , device  900  is in a communication state in which device  900  is outputting audio for a video or audio communication, as depicted by indicator  1120 . Device  900  also displays light  905  having a green color (represented by the hatching) to indicate device  900  is in the communication state. While in the communication state, device  900  performs volume adjustment operations in response to inputs (e.g., tap inputs  1122  and  1124 ) on the second and third portions of touch-sensitive surface  901 , and terminates the communication session in response to an input (e.g., tap input  1126 ) on the first portion of touch-sensitive surface  901 . In response to detecting input  1126  on first portion  901 - 1 , device  900  terminates the communication session, and resumes playing music, as depicted in  FIG.  11 J . 
       FIGS.  11 K- 11 N  depict various embodiments in which device  900  is in a state in which it does not perform a volume adjustment operation in response to inputs at second portion  901 - 2  or third portion  901 - 3  and, instead, performs an operation that is associated with first portion  901 - 1 . As mentioned above, this state can be a virtual assistant state, a state in which device  900  is performing a timer or alarm operation, a state in which device  900  is recording an outgoing audio message, or, in some embodiments, when audio playback is transitioning to (or from) device  900 , as discussed above with respect to  FIGS.  6 A- 6 X . In the embodiments depicted in  FIGS.  11 K- 11 N , device  900  displays light  905  having a large size to indicate device  900  is in the state in which the operations (e.g., volume adjustment operations) previously associated with portions  901 - 2  and  901 - 3  are disabled, and different operations (the operation(s) associated with first portion  901 - 1 ) are reassigned to the respective second and third portions. 
     In  FIG.  11 K , device  900  is performing an alert operation. For example, device  900  was previously playing music and, in response to determining that a timer has expired, device  900  transitioned to the alert state in which device  900  pauses the music and generates an alert, as depicted by indicators  1125 , that consists of an audio output and a display of light  905  having a large size and, optionally, a pulsing behavior. While device  900  is performing the alert operation, portions  901 - 2  and  901 - 3  are no longer associated with operations for performing a volume adjustment. Instead, portions  901 - 2  and  901 - 3  are configured to perform the same operation that is assigned to first portion  901 - 1 , which is an operation to terminate the alert. Thus, in response to any of inputs  1128 ,  1130 , and  1132 , device  900  terminates the alert, as depicted in  FIG.  11 L . In some embodiments, device  900  resumes playing the music after terminating the alert. In some embodiments, device  900  continues to pause the music, as depicted in  FIG.  11 L . 
     In  FIG.  11 M , device  900  has transitioned from a music playback state to a virtual assistant state where device  900  is performing a virtual assistant operation. Device  900  is outputting virtual assistant audio, as depicted by indicator  1135 , and displays light  905  having a large size and multi-color appearance depicted by different hatch patterns on light  905 . While device  900  is in the virtual assistant state, portions  901 - 2  and  901 - 3  are no longer associated with operations for performing a volume adjustment. Instead, portions  901 - 2  and  901 - 3  are configured to perform the same operation that is assigned to first portion  901 - 1 , which is an operation to terminate the virtual assistant state. Thus, in response to any of inputs  1134 ,  1136 , and  1138 , device  900  terminates the virtual assistant state, as depicted in  FIG.  11 N . In some embodiments, device  900  resumes playing the music after terminating the virtual assistant state, as depicted in  FIG.  11 N . In some embodiments, device  900  continues to pause the music after terminating the virtual assistant state. 
       FIGS.  11 O- 11 R  depict device  900  changing the state of light  905  in response to detecting various conditions and inputs. For example, in  FIG.  11 O , device  900  determines the music has been paused for a predetermined period of time and, in response, dims light  905 , as depicted in  FIG.  11 P . While light  905  is dimmed in  FIG.  11 P , device  900  detects input  1140  on first portion  901 - 1  and, in response, increases the brightness of light  905  and resumes playing music, as depicted in  FIG.  11 Q . In some embodiments, in response to input  1140 , device  900  increases the brightness of light  905  to the brightness in  FIG.  11 O  without performing the operation associated with the portion of the touch-sensitive surface  901  at which input  1140  was detected (e.g., the music remains paused). 
     In  FIG.  11 Q , device  900  is playing music at a volume of 5, as depicted by indicators  1110  and  1115 . Device  900  detects one or more inputs  1142  (e.g., a tap-and-hold input or a series of tap inputs) at portion  901 - 3  and, in response, reduces the volume to 0, and dims light  905  to an “off” state, as depicted in  FIG.  11 R . 
       FIGS.  12 A and  12 B  depict a flow diagram illustrating a method for managing media playback devices using an electronic device in accordance with some embodiments. Method  1200  is performed at a device (e.g.,  100 ,  300 ,  500 ,  900 ) with a touch-sensitive display (e.g.,  901 ,  902 ). Some operations in method  1200  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     In some embodiments, the electronic device (e.g.,  900 ) is a computer system (e.g., a speaker; a digital media player) that includes a touch-sensitive display (e.g.,  901 ,  902 ) having a first portion (e.g.,  901 - 1 ) and a second portion (e.g.,  901 - 2 ;  901 - 3 ), wherein the touch-sensitive display includes one or more physical features (e.g.,  901 A;  901 B) (e.g., ridges, bumps, markings, textures, etchings, indicia) that distinguishes the second portion from the first portion (e.g., the second portion is different from the first portion). In some embodiments, the second portion is visually and/or texturally different form the first portion. In some embodiments, the one or more physical features are provided (e.g., printed, displayed, etched, engraved, overlaid, molded) on and/or below the touch-sensitive display. In some embodiments, the first portion is associated with a first operation. In some embodiments, the second portion is not associated with the first operation. In some embodiments, the second portion is conditionally associated with the first operation based, for example, on an operation that can be performed in response to an input at the second portion. 
     As described below, method  1200  provides an intuitive way for managing media playback devices. The method reduces the cognitive burden on a user for managing media playback devices, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to manage media playback devices faster and more efficiently conserves power and increases the time between battery charges. 
     At method  1200 , while the first portion (e.g.,  901 - 1 ) of the touch-sensitive display (e.g.,  901 ) is configured to cause the computer system (e.g.,  900 ) to perform a first operation (e.g., a playback control operation; pause; play; mute; unmute) in response to detecting an input on the first portion, the computer system outputs ( 1202 ) (e.g., displays) a visual indicator (e.g.,  905 ) (e.g., a status light) on the touch-sensitive display (e.g., via one or more displays  902 ). The visual indicator occupies at least a subset of the first portion of the touch-sensitive display. A first visual property (e.g., size, brightness, color, and/or pulse behavior) of the visual indicator indicates an operational state (e.g., active/inactive) of the second portion (e.g.,  901 - 2 ;  901 - 3 ) for (e.g., with respect to) performing a second operation (e.g., volume up; volume down) different from the first operation (e.g., one or more operations that are different from the first operation) (e.g., the status light indicates whether or not the second portion of the touch-sensitive surface is configured or operable to perform the second operation(s)). Outputting a visual indicator on the touch-sensitive display that occupies at least a subset of the first portion of the display, wherein a first visual property of the visual indicator indicates an operational state of the second portion for performing a second operation different from the first operation, provides feedback to a user of the computer system of an operational state of the second portion of the touch-sensitive display. Providing improved feedback reduces the number of inputs at the computer system (e.g., by informing the user of the operational state of the second portion of the touch-sensitive display without requiring the user to provide input to discern the operational state), enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In accordance with a determination that the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display (e.g.,  901 ) is operable (e.g., configured) to initiate a process for performing the second operation (e.g., the second portion of the touch-sensitive surface is configured to perform the second operation), the computer system (e.g.,  900 ) outputs ( 1204 ) the visual indicator (e.g.,  905 ) having a first variation (e.g., value, shape, pattern, and/or size) of the first visual property (e.g., a first size (e.g., a size that does not include the second portion, or a majority of the second portion, of the touch-sensitive display); light  905  having a size shown in  FIG.  11 A,  11 C,  11 E,  11 G , and/or  11 I). 
     In accordance with a determination that the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display (e.g.,  901 ) is not operable (e.g., configured) to initiate the process for performing the second operation (e.g., the second portion of the touch-sensitive surface is not configured to perform the second operation), the computer system (e.g.,  900 ) outputs ( 1206 ) the visual indicator (e.g.,  905 ) having a second variation (e.g., value, shape, pattern, and/or size) of the first visual property different from the first variation (e.g., a second size different from the first size) (e.g., a larger size than the first size) (e.g., a size that includes at least a subset (portion), or a majority, of the second portion of the touch-sensitive display) (e.g., light  905  having a size shown in  FIG.  11 K  and/or  FIG.  11 M ). In some embodiments, outputting the status light having the larger size includes outputting the status light at the first portion of the touch-sensitive surface and at least a portion of the second portion of the touch-sensitive surface (e.g., covering the first portion and overlapping at least a portion of the second portion). 
     In method  1200 , the computer system (e.g.,  900 ) detects ( 1208 ) an input (e.g.,  1112 ;  1114 ;  1116 ;  1118 ;  1122 ;  1124 ;  1126 ;  1128 ;  1130 ;  1132 ;  1134 ;  1136 ;  1138 ;  1140 ;  1142 ) (e.g., a touch input) directed to the touch-sensitive display (e.g.,  901 ). 
     In response ( 1210 ) to detecting the input directed to the touch-sensitive display (e.g.,  901 ), the computer system (e.g.,  900 ) performs the following steps. In accordance with a determination that the input (e.g.,  1114 ;  1116 ;  1122 ;  1124 ;  1142 ) is directed to the second portion (e.g.,  901 - 2 ) of the touch-sensitive display (e.g.,  901 ) (e.g., at least a predefined amount (e.g., 10%, 25%, 35%, 45%, 51%, 55%, 60%, 75%, 85%, 95%, 99%, 100%, more than 50%) of the touch contact is located within the second portion) while the visual indicator has the first variation of the first visual property (e.g., a small displayed size) (e.g., light  905  has a size shown in  FIG.  11 A,  11 C,  11 E,  11 G , and/or  11 I), the computer system initiates ( 1212 ) a process for performing the second operation (e.g., perform a volume adjustment). In accordance with a determination that the input (e.g.,  1128 ;  1132 ;  1134 ;  1138 ) is directed to the second portion of the touch-sensitive display while the visual indicator has the second variation of the first visual property (e.g., a large displayed size) (e.g., light  905  having a size shown in  FIG.  11 K  and/or  FIG.  11 M ), the computer system forgoes ( 1214 ) initiating a process for performing the second operation (e.g., do not perform a volume adjustment). In some embodiments, the computer system performs the first operation when an input is detected at the second portion of the touch-sensitive surface when the status light has the second variation of the visual property. 
     In some embodiments, in response to detecting the input (e.g.,  1112 ;  1118 ;  1126 ;  1140 ) directed to the touch-sensitive display (e.g.,  901 ) while the visual indicator (e.g.,  905 ) has the first variation of the first visual property (e.g., a small displayed size), and in accordance with a determination that the input is directed to the first portion (e.g.,  901 - 1 ) of the touch-sensitive display (e.g., at least a predefined amount (e.g., 25%, 35%, 45%, 51%, 55%, 60%, 75%, 85%, 95%, 99%, 100%, more than 50%) of the touch contact is located within the first portion), the computer system (e.g.,  900 ) initiates a process for performing the first operation (e.g., perform a playback control operation; pause; play; mute; unmute). In some embodiments, in response to detecting the input (e.g.,  1130 ;  1136 ) directed to the touch-sensitive display while the visual indicator has the second variation of the first visual property (e.g., a large displayed size), and in accordance with a determination that the input is directed to the first portion (e.g.,  901 - 1 ) of the touch-sensitive display (e.g.,  901 ), the computer system (e.g.,  900 ) initiates a process for performing the first operation. In some embodiments, when the input is directed to the first portion of the touch-sensitive display, the first operation is performed without regard for whether the status light has the first or second variation of the first visual property. 
     In some embodiments, the first visual property is a size of the visual indicator (e.g.,  905 ). In some embodiments, the first variation of the first visual property is a first size (e.g., a size that does not include the second portion of the touch-sensitive display) (e.g., light  905  has the size shown in  FIG.  11 A,  11 C,  11 E,  11 G , and/or  11 I). In some embodiments, the second variation of the first visual property is a second size that is greater (e.g., larger) than the first size (e.g., a size that includes at least a subset of the second portion of the touch-sensitive display) (e.g., light  905  has the size shown in  FIG.  11 K  and/or  FIG.  11 M ). In some embodiments, the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display is not operable to initiate the process for performing the second operation when the visual indicator has the second size. In some embodiments, when the status light has the larger size that includes (e.g., encompasses) both the first portion of the touch-sensitive display and a subset (portion) of the second portion of the touch-sensitive display, the second portion of the touch-sensitive display is not operable to perform the second operation (e.g., operable to initiate the process for performing the second operation). 
     In some embodiments, in response to detecting the input (e.g.,  1114 ;  1116 ;  1122 ;  1124 ;  1142 ) directed to the touch-sensitive display (e.g.,  901 ), and in accordance with a determination that the input is directed to the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display while the visual indicator (e.g.,  905 ) has the first size (e.g., a size shown in  FIG.  11 A,  11 C,  11 E,  11 G , and/or  11 I), the computer system (e.g.,  900 ) initiates the process for performing the second operation (e.g., performing a volume adjustment). In response to detecting the input (e.g.,  1128 ;  1132 ;  1134 ;  1138 ) directed to the touch-sensitive display (e.g.,  901 ), and in accordance with a determination that the input is directed to the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display while the visual indicator has the second size (e.g., a size shown in  FIG.  11 K  and/or  FIG.  11 M ), the computer system forgoes initiating the process for performing the second operation (e.g., do not perform a volume adjustment) (and, in some embodiments, initiating a process for performing the first operation). In some embodiments, when the status light has the smaller size (e.g., that does not include the second portion of the touch-sensitive display), the second portion of the touch-sensitive display is operable to perform operations other than the first operation (e.g., the second operation) (e.g., operable to initiate one or more processes for performing operations other than the first operation). 
     In some embodiments, in response to detecting the input directed to the touch-sensitive display, and in accordance with a determination that the input (e.g.,  1128 ;  1132 ;  1134 ;  1138 ) is directed to the second portion (e.g.,  901 - 2 ;  901 - 3 ) of the touch-sensitive display (e.g.,  901 ) while the visual indicator has the second variation of the first visual property (e.g., a displayed size that includes at least a subset of the second portion of the touch-sensitive display) (e.g., light  905  has the size shown in  FIG.  11 K  and/or  FIG.  11 M ), the computer system (e.g.,  900 ) initiates a process for performing the first operation (e.g., perform a playback control operation; pause; play; mute; unmute). In some embodiments, the second portion of the touch-sensitive display is operable to perform the first operation (e.g., operable to initiate a process for performing the first operation) when the status light has the larger displayed size that encompasses the first portion of the touch-sensitive display and at least a subset of the second portion of the touch-sensitive display. 
     In some embodiments, performing the first operation includes the computer system (e.g.,  900 ) starting to output (e.g., unmuting, initiating/resuming playback) audio (e.g., as indicated by indicator  1110 ) if audio is not being output (e.g., audio (e.g., music, podcasts, videoconference audio, phone audio) generated at the computer system) or ceasing to output audio if audio is being output (e.g., muting first audio generated at the computer system, pausing playback of first audio generated at the computer system). 
     In some embodiments, performing the first operation includes the computer system (e.g.,  900 ) initiating a task (e.g., initiating a request (e.g., for a virtual assistant), setting a timer, setting an alarm) or canceling a task (e.g., canceling a request (e.g., for a virtual assistant), canceling or disabling a timer, canceling or disabling an alarm) (e.g., see  FIGS.  11 K- 11 N ). 
     In some embodiments, performing the second operation includes the computer system (e.g.,  900 ) initiating a volume adjustment (e.g., increase volume; decrease volume) (e.g., see  FIGS.  11 C- 11 F ). 
     In some embodiments, performing the second operation (e.g., a volume adjustment) includes the computer system (e.g.,  900 ) modifying a second visual property (e.g., size, brightness, color, and/or pulse behavior) of the visual indicator different from the first visual property (e.g., see pulsing of light  905  shown in  FIGS.  11 D and  11 F ). Modifying a second visual property of the visual indicator different from the first visual property provides feedback to a user of the computer system that the second operation is being performed. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the second visual property is a display state (e.g., brightness, behavior) of the visual indicator (e.g.,  905 ). In some embodiments, modifying the second visual property includes the computer system (e.g.,  900 ) modulating the display state of the visual indicator (e.g., pulsing the visual indicator, blinking the visual indicator) in response to the first input (e.g., to provide feedback that the first input was received) (e.g., see pulsing of light  905  shown in  FIGS.  11 D and  11 F ). Modulating the display state of the visual indicator in response to the first input provides feedback to a user of the computer system that the first input is being received at the computer system. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the first visual property is color of the visual indicator (e.g.,  905 ). In some embodiments, the computer system (e.g.,  900 ) is in a first state (e.g., the virtual assistant state shown in  FIG.  11 M ) in which the first portion (e.g.,  901 - 1 ) of the touch-sensitive display (e.g.,  901 ) is configured to cause the computer system to perform the first operation (e.g., canceling the virtual assistant). In some embodiments, the computer system detects a transition from the first state to a second state (e.g., the music playback state in  FIG.  11 N ) in which the first portion (e.g., and/or second portion) of the touch-sensitive display is configured to cause the computer system to perform a third operation (e.g., a playback control operation; pause; play; mute; unmute) (e.g., an operation different from the first operation) in response to detecting an input on the first portion (e.g., and/or second portion) of the touch-sensitive display. In some embodiments, in response to detecting the transition to the second state, the computer system modifies a color (e.g., one or more colors) of the visual indicator (e.g., light  905  changes from multi-color in  FIG.  11 M  to a white color in  FIG.  11 N ). Modifying a color of the visual indicator provides feedback to a user of the computer system that the computer system has transitioned from the first state to a second state in which the first portion of the touch-sensitive display is configured to cause the computer system to perform a third operation in response to detecting an input on the first portion of the touch-sensitive display. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the status light changes colors based on the operation to be performed by the computer system. 
     In some embodiments, the modified color of the visual indicator (e.g.,  905 ) is a first set of one or more colors (e.g., white) when the third operation is associated with music or an alarm (e.g., an operation for controlling playback and/or handoff of music; an operation for setting, canceling, or silencing an alarm). 
     In some embodiments, the modified color of the visual indicator (e.g.,  905 ) is a second set of one or more colors (e.g., multicolor (e.g., a multicolor pattern); different from the first set of one or more colors) when the third operation is associated with a virtual assistant (e.g., an operation for initiating/fulfilling a request or command using a virtual assistant). 
     In some embodiments, the modified color of the visual indicator (e.g.,  905 ) is a third set of one or more colors (e.g., green; different from the first and/or second set of one or more colors) when the third operation is associated with communication audio (e.g., audio for a call; audio for a video communication (e.g., video chat); audio being transmitted to the computer system (e.g., from an external source such as a different computer system)). 
     In some embodiments, the modified color of the visual indicator (e.g.,  905 ) is a fourth set of one or more colors (e.g., amber, yellow; different from the first, second, and/or third set of one or more colors) when the second state is a low power mode of the computer system (e.g., the power supply is below a predetermined threshold). 
     In some embodiments, the modified color of the visual indicator (e.g.,  905 ) is a fifth set of one or more colors (e.g., red; different from the first, second, third, and/or fourth set of one or more colors) when the third operation is associated with a reset command (e.g., an operation for initiating a reset of the computer system). 
     In some embodiments, modifying the color of the visual indicator (e.g.,  905 ) includes animating a color change of the visual indicator based on an audio signal (e.g., an output audio produced at the computer system; an audio signal of an input command received at the computer system). Animating a color change of the visual indicator based on an audio signal provides feedback to a user of the computer system that an operation to be performed at the computer system is associated with the audio signal. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. In some embodiments, the animated color change includes changing colors and, optionally, a pattern and/or behavior of the status light in response to changes in the audio signal. In some embodiments, the animation of the light includes a changing pattern and/or behavior of the status light (e.g., in response to changes in the audio signal) without changing color. 
     In some embodiments, in accordance with a determination that the computer system (e.g.,  900 ) has not received an input (e.g., user input) for at least a predetermined amount of time (e.g., 30 seconds, 1 minute, 5 minutes), the computer system decreases a brightness of the visual indicator (e.g.,  905 ) (e.g., decreasing the brightness to a non-zero value; see  FIGS.  11 O and  11 P ). In some embodiments, the computer system decreases the brightness of the visual indicator when the computer system does not detect any inputs (e.g., user inputs) for a predetermined period of time in order to conserve power and/or longevity of the touch-sensitive display. 
     In some embodiments, while the visual indicator (e.g.,  905 ) has the decreased brightness (e.g., as shown in  FIG.  11 P ), the computer system (e.g.,  900 ) detects an input (e.g.,  1140 ) (e.g., a user input). In response to detecting the input, the computer system increases the brightness of the visual indicator (e.g., increasing the brightness of the visual indicator to its original brightness) (e.g., see  FIG.  11 Q ). Increasing the brightness of the visual indicator in response to detecting an input after the visual indicator has a decreased brightness provides feedback to a user of the computer system that the input was received at the computer system and that the computer system is in a state in which the computer system is responsive to input. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     In some embodiments, the computer system (e.g.,  900 ) is configured to generate output audio based on a volume setting (e.g., represented using indicator  1115 ). In some embodiments, in accordance with a determination that the volume setting is greater than zero, the computer system outputs the visual indicator (e.g.,  905 ) (e.g., see  FIG.  11 Q ). In some embodiments, in accordance with a determination that the volume setting is zero, the computer system ceases output of the visual indicator (e.g., the status light is not displayed when the volume is turned off) (e.g., see  FIG.  11 R ). Ceasing output of the visual indicator when the volume setting is zero provides feedback to a user of the computer system that the computer system is not configured to generate output audio. Providing improved feedback reduces the number of inputs at the computer system, enhances the operability of the computer system, and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the computer system) which, additionally, reduces power usage and improves battery life of the computer system by enabling the user to use the system more quickly and efficiently. 
     Note that details of the processes described above with respect to method  1200  (e.g.,  FIGS.  12 A and  12 B ) are also applicable in an analogous manner to the methods described below. For example, methods  700 ,  800 , and  1000  optionally include one or more of the characteristics of the various methods described above with reference to method  1200 . For example, these methods can include using light to indicate an operational state of a computer system having a touch-sensitive display, as discussed in method  1200 . For brevity, these details are not repeated below. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to manage media playback devices. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to customize media playback. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of managing media playback devices, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, media content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the electronic device, media playback history or patterns, or publicly available information.
