     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for navigating user interfaces using hand gestures. 
     BACKGROUND 
     Users of smartphones and other personal electronic devices are more frequently using their devices. Some existing techniques allow users to navigate user interfaces on their devices. 
     BRIEF SUMMARY 
     Some techniques for navigating user interfaces using hand gestures with electronic devices, however, are generally cumbersome and inefficient. For example, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Existing techniques require a lot of time, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present technique provides users of electronic devices with faster, more efficient methods and interfaces for navigating user interfaces using hand gestures. Such methods and interfaces optionally complement or replace other methods for navigating user interfaces using hand gestures. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges.

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for navigating user interfaces using hand gestures. For example, users may want to navigate user interfaces without touching the display of their devices. Such techniques can reduce the cognitive and/or physical burden on a user who navigate user interfaces, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS.  1 A- 1 B,  2 ,  3 ,  4 A- 4 B, and  5 A- 5 B  provide a description of exemplary devices for performing the techniques for navigating user interfaces using hand gestures.  FIG.  6    illustrates an exemplary set of hand gestures, in accordance with some embodiments.

FIGS.  8 A- 8 J  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIGS.  9 A- 9 H  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIGS.  10 A- 10 F  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIGS.  11 A- 11 H  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIGS.  12 A- 12 J  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. FIGS.  13 A- 13 G illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIG.  14    illustrates exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIG.  15    is a flow diagram illustrating a method for navigating user interfaces using hand gestures, in accordance with some embodiments.  FIG.  16    is a flow diagram illustrating a method for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in  FIG.  6   ,  FIGS.  7 A- 7 AA ,  FIGS.  8 A- 8 J ,  FIGS.  9 A- 9 H ,  FIGS.  10 A- 10 F ,  FIGS.  11 A- 11 H ,  FIGS.  12 A- 12 J ,  FIGS.  13 A- 13 G , and  FIG.  14    are used to illustrate the processes described below, including the processes in  FIG.  15    and  FIG.  16   . 
     In addition, in methods described herein where one or more steps are contingent upon one or more conditions having been met, it should be understood that the described method can be repeated in multiple repetitions so that over the course of the repetitions all of the conditions upon which steps in the method are contingent have been met in different repetitions of the method. For example, if a method requires performing a first step if a condition is satisfied, and a second step if the condition is not satisfied, then a person of ordinary skill would appreciate that the claimed steps are repeated until the condition has been both satisfied and not satisfied, in no particular order. Thus, a method described with one or more steps that are contingent upon one or more conditions having been met could be rewritten as a method that is repeated until each of the conditions described in the method has been met. This, however, is not required of system or computer readable medium claims where the system or computer readable medium contains instructions for performing the contingent operations based on the satisfaction of the corresponding one or more conditions and thus is capable of determining whether the contingency has or has not been satisfied without explicitly repeating steps of a method until all of the conditions upon which steps in the method are contingent have been met. A person having ordinary skill in the art would also understand that, similar to a method with contingent steps, a system or computer readable storage medium can repeat the steps of a method as many times as are needed to ensure that all of the contingent steps have been performed. 
     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.

The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with one or more input devices. In some embodiments, the one or more input devices include a touch-sensitive surface (e.g., a trackpad, as part of a touch-sensitive display). In some embodiments, the one or more input devices include one or more camera sensors (e.g., one or more optical sensors  164  and/or one or more depth camera sensors  175 ), such as for tracking a user&#39;s gestures (e.g., hand gestures and/or air gestures) as 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. In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independently of an input element that is a part of the device) and is based on detected motion of a portion of the user&#39;s body through the air including motion of the user&#39;s body relative to an absolute reference (e.g., an angle of the user&#39;s arm relative to the ground or a distance of the user&#39;s hand relative to the ground), relative to another portion of the user&#39;s body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user&#39;s body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user&#39;s body). 
     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-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     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 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, California. 
     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 (such as computer programs (e.g., including instructions)), 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 computer programs (e.g., sets of instructions or including instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), 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  1500  and  1600  ( FIGS.  15 - 16   ). 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, 5, 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.  6    illustrates an exemplary set of hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
       FIG.  6    illustrates an exemplary set of hand gestures that can be detected by computer system  600 . Computer system  600  includes input mechanism  602   a  (e.g., a crown of a watch), input mechanism  602   b  (e.g., a side button), and display screen  602   c . In some embodiments, computer system  600  includes one or more components of devices  100 ,  300 , and/or  500 . In some embodiments, computer system  600  is a wearable device, such as a watch. In some embodiments, input mechanisms  602   a  and  602   b  can include one or more components and/or characteristics of input mechanisms  506  and  608  described above in relation to  FIG.  5 A . In some embodiments, display screen  602   c  is a touch-sensitive display and includes one or more components and/or characteristics as described above in relation to touch screen  504 . 
     As illustrated in  FIG.  6   , computer system  600  is being worn around the wrist of a user and is away from hand  622 . Computer system  600  includes one or more accelerometers, gyroscopes, and/or biometric sensors to detect the various hand gestures and/or movement (e.g., such as tilting) of computer system  600 . At  FIG.  6   , one or more of the biometric sensors include an optical sensor and/or heart rate sensor that computer system  600  utilizes to detect various hand gestures. In some embodiments, computer system  600  can detect hand gestures using one or more sensors that are different from an optical/heart rate sensor. 
       FIG.  6    illustrates exemplary hand gestures that can be detected by computer system  600  (e.g., via an optical/heart rate sensor). As illustrated in  FIG.  6   , the hand gestures include neutral gesture/position  610 , clench gesture  620 , double clench gesture  630 , pinch gesture  640 , and double pinch gesture  650 . While these hand gestures (e.g.,  610 ,  620 ,  630 ,  640 , and  650 ) are discussed throughout this application, hand gestures (e.g., multi-finger tap hand gestures and/or triple (quadruple, quintuple) clench/pinch gestures) and one or more combinations of these hand gestures are contemplated as being detectable by computer system  600  (e.g., via an optical/heart rate sensor) and/or used to perform one or more operations as described below. Thus, the hand gestures provided herein are for exemplary purposes only, and the embodiments described herein are not limited to these particular hand gestures. In addition, the hand gestures described herein are not directed to (e.g., is not captured by) one or more cameras of computer system  600 . In addition, the hand gestures described herein do not contact display screen  602   c  and/or are not performed in front of display screen  602   c  (e.g., in order for the hand gestures to be detected by computer system  600 ). 
     As illustrated in  FIG.  6   , neutral hand gesture/position  610  is a hand gesture/position, where none of the fingertips of hand  622  are touching any portion of hand  622 . Clench gesture  620  is a hand gesture, where one or more the fingers of hand  622  are touching another portion of the hand of the user, such that the palm of a user&#39;s hand when the user is forming a fist. Double clench gesture  630  is a combination (and/or sequence) of neutral gesture/position  610  and clench gesture  620 , where the fingers of hand  622  are closed to form a first clench gesture (e.g., first portion  630   a ), opened to form a neutral gesture/position (e.g., second portion  630   b ), and closed again to form a second clench gesture (e.g., third portion  630   c ). Thus, a double clench gesture is a gesture that includes multiple (e.g., two) instances (e.g., first portion  630   a  and third portion  630   c ) of a clench gesture that are detected within a predetermined period of time (e.g., 0-2 seconds). Pinch gesture  640  is a hand gesture, where one or more of the fingers of hand  622  are touching (e.g., two fingers) each other. A pinch gesture is different from a clench gesture because a first is not formed when making a pinch gesture while the first is formed when making a clench gesture. Double pinch gesture  650  is a combination (and/or sequence) of neutral gesture/position  610  and pinch gesture  640 , where the fingers of hand  622  touch to form a first pinch gesture (e.g., first portion  650   a ), opened to form a neutral gesture/position (e.g., second portion  650   b ), and closed again to form a second pinch gesture (e.g., third portion  650   c ). Thus, a double pinch gesture is a gesture that includes multiple (e.g., two) instances (e.g., first portion  650   a  and third portion  650   c ) of a pinch gesture that are detected with a period that are detected within a predetermined period of time (e.g., 0-2 seconds). As illustrated in  FIG.  6   , double clench gesture  630  and clench gesture  620  do not include multiple instances of pinch gesture  640 , and double pinch gesture  650  and pinch gesture  640  do not include multiple instances of clench gesture  620 . In some embodiments, when two pinch gestures are detected within a predetermined period of time, computer system  600  registers (or detects) the two gestures as being a double pinch gesture. In some embodiments, when two pinch gestures are not detected within a predetermined period of time, computer system  600  registers (or detects) the two gestures as being two individual pinch gestures (e.g., without registering a double pinch gesture). In some embodiments, when two clench gestures are detected within a predetermined period of time, computer system  600  registers (or detects) the two gestures as being a double clench gesture. In some embodiments, when two clench gestures are not detected within a predetermined period of time, computer system  600  registers (or detects) the two gestures as being two individual clench gestures (e.g., without registering a double clench gesture). 
       FIGS.  7 A- 7 AA  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
       FIGS.  7 A- 7 G  illustrate exemplary user interfaces for responding to an incoming alert (e.g., timer alert) using hand gestures.  FIG.  7 A  illustrates computer system  600  displaying clock user interface  710  on display screen  602   c , which includes a current time (e.g.,  10 : 09 ). While computer system  600  is displaying clock user interface  710 , hand  622  is in the neutral position (e.g.,  610  in  FIG.  6   ). At  FIG.  7 A , computer system  600  receives an incoming alert from a timer application (e.g., that is installed on computer system  600 ). As illustrated in  FIG.  7 B , in response to receiving the incoming alert from the timer application, computer system  600  displays timer user interface  712 . Timer user interface  712  includes stop control  712   a  (e.g., that, when activated, causes computer system  600  to stop outputting an audible sound related to the incoming alert) and repeat control  712   b  (e.g., that, when activated, causes computer system  600  to repeat the timer that is related to the incoming alert) and an indication that a timer has completed (e.g., “TIMER DONE”). At  FIG.  7 C , computer system  600  detects pinch gesture  750   c . However, as illustrated in  FIG.  7 D , computer system  600  maintains display of timer user interface  712  and does not perform any operations in response to pinch gesture  750   c  because computer system  600  is not operating in a hand gesture navigation mode (e.g., and/or an accessibility mode). In some embodiments, computer system  600  does not detect pinch gesture  750   c  because computer system  600  is not operating in a hand gesture navigation mode. 
     At  FIG.  7 D , computer system  600  detects double clench gesture  750   d . At  FIG.  7 E , in response to detecting double clench gesture  750   d , computer system  600  begins operating in a hand gesture navigation mode. At  FIG.  7 E , computer system  600  detects pinch gesture  750   e  (e.g., a second pinch gesture). As illustrated in  FIG.  7 F , in response to detecting pinch gesture  750   e , computer system  600  displays a focus indicator around stop control  712   a  because computer system  600  is operating in the hand gesture navigation mode. Computer system  600  displays the focus indicator around stop control  712   a  to indicate that stop control  712   a  can be activated in response to computer system  600  detecting a particular hand gesture. In contrast, computer system  600  is not displaying a focus indicator around repeat control  712   b  in  FIG.  7 F . Thus, repeat control  712   b  cannot be activated in response to computer system  600  detecting a particular hand gesture (e.g., before repeat control  712   b  is displayed with a focus indicator). At  FIG.  7 F , computer system  600  detects clench gesture  750   f  Δt  FIG.  7 G , in response to detecting clench gesture  750   f , computer system  600  activates stop control  712   a . Upon activating stop control  712   a , computer system  600  ceases to display timer user interface  712 , ceases to output audible sound related to the incoming alert, and re-displays clock user interface  710  (e.g., as illustrated in  FIG.  7 G ). 
       FIGS.  7 G- 7 J  illustrate exemplary user interfaces for responding to an incoming alert (e.g., incoming call) using hand gestures. As discussed above,  FIG.  7 G  illustrates computer system  600  displaying clock user interface  710  while operating in the hand gesture navigation mode. At  FIG.  7 G , computer system  600  receives an alert that corresponds to an incoming phone call. As illustrated in  FIG.  7 H , in response to receiving the alert, computer system  600  displays phone user interface  714  that includes call identifier  714   a  (e.g., “JOHN APPLESEED INCOMING CALL”), which indicates that computer system  600  is receiving an incoming call from John Appleseed. Phone user interface  714  also includes decline control  714   b  (e.g., that, when activated, causes computer system  600  to decline the phone call), answer control  714   c  (e.g., that, when activated, causes computer system  600  to answer the phone call), and additional options control  714   d  (e.g., that, when activated, causes computer system  600  to display additional options for responding to the incoming phone call). As illustrated in  FIG.  7 H , computer system  600  displays hand gesture notification  716 , which indicates that a user can answer the phone call by providing a double clench gesture (e.g., instead of providing multiple gestures (e.g., one or more pinch gestures to navigate to answer control  714   c  and a clench gesture to navigate to answer control  714   c , using one or more techniques as discussed in relation to  FIGS.  7 C- 7 G ) to answer the phone call). In some embodiments, computer system  600  displays hand gesture notification  716  because a determination is made that computer system  600  is operating in a hand gesture navigation mode and/or computer system  600  is operating in a use context where a particular type of operation (e.g., answering a phone call, stopping an alarm, and/or replying to a text message) can be completed via a single hand gesture (e.g., a predetermined hand gesture). In some embodiments, computer system  600  displays other and/or different hand gesture notifications (e.g., from hand gesture  716 ) to inform the user that one or more other gestures can be used to perform an operation. 
     At  FIG.  7 I , computer system  600  detects double clench gesture  750   i . As illustrated in  FIG.  7 J , in response to detecting double clench gesture  750   i , computer system  600  replaces call identifier  714   a  with elapse time indicator  714   e , which indicates that the incoming phone call has been answered, and display volume control  714   f  (e.g., that, when activated, causes the volume level of one or more speakers of computer system  600  to be adjusted). In other words, in response to detecting double clench gesture  750   i , computer system  600  answers the incoming phone call. In some embodiments, computer system  600  performs a different operation (e.g., as discussed in relation to  FIGS.  7 D- 7 E and  7 L- 7 M ) in response to detecting a double clench gesture while an incoming alert is not being received (and/or has not been received within a predetermined period of time) than the operation that is performed (e.g., as discussed in relation to  FIGS.  7 I- 7 L ) while an incoming alert is being received (e.g., and/or has been received within a predetermined period of time). 
       FIGS.  7 I- 7 U  illustrate exemplary user interfaces for navigating a user interface using hand gestures and a moving cursor. In particular,  FIGS.  7 I- 7 U  illustrate an exemplary scenario where a workout tracker is ended using hand gestures and a moving cursor.  FIG.  7 K  illustrates computer system  600  displaying workout user interface  718  that includes a list of workout metrics. While displaying workout user interface  718 , computer system  600  detects double clench gesture  750   l  at  FIG.  7 L . As illustrated in  FIG.  7 M , in response to detecting double clench gesture  750   l , computer system  600  displays menu  732  that includes digital hardware operation control  732   a , moving cursor control  732   b , interaction control  732   c , and additional options control  732   d . Menu  732  includes control identifier  708  (“DIGITAL CROWN”) that identifies the control that is currently in focused (e.g., the black box around digital hardware operation control  732   a  in  FIG.  7 M ). In response to detecting activation of digital hardware operation control  732   a , computer system  600  begins operating in a digital hardware operation mode (e.g., a different hand gesture navigation mode). In response to detecting activation of interaction control  732   c , computer system  600  replaces menu  732  with a menu with controls, that when activated, cause computer system  600  to perform different operations that correspond to various gestures being detected at a location on computer system  600  (e.g., as discussed below in relation to  FIG.  7 Z ). In response to detecting activation of additional options control  732   d , computer system  600  replaces menu  732  with a menu that includes additional controls (e.g., as discussed below in relation to  FIG.  7 Z ). 
     As illustrated in  FIG.  7 M , in response to detecting double clench gesture  750   l , computer system  600  displays focus indicator around digital hardware operation control  732   a  to indicate that digital hardware operation control  732   a  can be activated in response to computer system  600  detecting one or more hand gestures. At  FIG.  7 M , computer system  600  detects pinch gesture  750   m . As illustrated in  FIG.  7 N , in response to detecting pinch gesture  750   m , computer system  600  moves focus indicator to the right, such that the focus indicator is around moving cursor control  732   b  and no longer around digital hardware operation control  732   a . Notably, in response to detecting pinch gesture  750   m , computer system  600  moves the focus indicator from one control to the next control (e.g., in terms of location) on a user interface. At  FIG.  7 N , computer system  600  detects clench gesture  750   n  while focus indicator is displayed around moving cursor control  732   b.    
     As illustrated in  FIG.  7 O , in response to detecting clench gesture  750   n , computer system  600  ceases to display menu  732  and displays cursor  742  at a location on workout user interface  718 . At  FIG.  7 O , in response to detecting clench gesture  750   n , computer system  600  begins operating in a moving cursor operation mode (e.g., another hand gesture operation mode). At  FIG.  7 P , computer system  600  detects (e.g., via one or more accelerometers and/or gyroscopes via a sensor that is different from an optical/heart rate sensor, and/or via a sensor that is different from the sensor that detects one or more hand gestures) that computer system  600  is being tilted (e.g., moved) to the left (e.g.,  750   p ). At  FIG.  7 P , in response to detecting that computer system  600  is being tilted to the left, computer system  600  moves cursor  742  to the left based on the amount of tilting and/or speed of the tilting being detected by computer system  600 . As illustrated in  FIG.  7 P , cursor  742  is moved toward the left edge of workout user interface  718 . At  FIG.  7 P , a determination is made that cursor  742  is positioned at (e.g., and/or near) the left edge of workout user interface  718  (e.g., for a predetermined period of time). As illustrated in  FIGS.  7 Q- 7 R , because the determination is made that cursor  742  is positioned on the left edge of workout user interface  718 , computer system  600  displays an animation that slides workout user interface  718  off of the right edge of display screen  602   c , and slides workout control user interface onto the display screen  602   c  from the left edge of display screen (e.g., slides to the right). Thus, because a determination is made that cursor  742  is positioned at (e.g., and/or near), computer system  600  replaces the currently displayed user interface with another user interface. 
     As illustrated in  FIG.  7 R , workout control user interface  720  includes lock control  720   a  (e.g., that, when activated, causes computer system  600  to ignore touch inputs detected on computer system  600 ), new control  720   b  (e.g., that, when activated, causes computer system  600  to initiate a new workout tracker), end control  720   c  (e.g., that, when activated, causes computer system  600  to stop a workout tracker that is currently tracking workout activity), and pause control  730   d  (e.g., that, when activated, cause computer system  600  to pause a workout tracker that is currently tracking workout activity). As illustrated in  FIG.  7 R , hand  622  is in the neutral position (e.g.,  610  in  FIG.  6   ), and cursor  742  is positioned over end control  720   c . At  FIG.  7 S , a period of time has passed since cursor  742  was first positioned over end control  720   c  (and/or at the current location of cursor  742 ) (e.g., and hand  622  has remained in the neutral position). As illustrated in  FIG.  7 S , computer system  600  displays cursor  742  with indication  744 . Indication  744  indicates an amount of time before an operation will be performed (e.g., an activation operation) that corresponds to the location of cursor  742 , such as activating end control  720   c  and/or displaying a menu that includes one or more controls to perform an operation that corresponds to the location of cursor  742  (e.g., menu  732  of  FIG.  7 M ). Accordingly, while cursor  742  is displayed at a location that corresponds to a user interface object, such as a control, computer system  600  displays an animation of the size of indication  744  and/or fills up cursor  742  over a period of time (e.g., a period of time that indicates the remaining time before an operation will be performed). At  FIG.  7 S , indication  744  filling up roughly half of cursor  742  indicates roughly half the time has passed (e.g., since cursor  742  has been positioned over end control  720   c ) before computer system  600  can perform an operation corresponds to the location of cursor  742 . Looking back at  FIGS.  7 Q- 7 R , computer system  600  did not display an indication with cursor  742  while computer system  600  was not displayed on a user interface and/or at the edge of the display, irrespective of how long the computer system  600  was displayed at a particular location. Thus, in some embodiments, computer system  600  only displays an animation that includes indication  744  when moving cursor  742  is over a user interface object (e.g., a selectable and/or (able to be activated) user interface object, a user interface object that could be activated via one or more gestures that are detected on display screen  602   c ). 
     At  FIG.  7 S , more time has passed since cursor  742  was first positioned over end control  720   c  (e.g., and hand  622  has remained in the neutral position). As illustrated in  FIG.  7 T , computer system  600  has updated indication  744 , such that indication  744  has filled up all of cursor  742 . At  FIG.  7 T , a determination is made that cursor  742  has been positioned over end control  720   c  for a predetermined period of time (e.g., 1-5 seconds). At  FIG.  7 U , because the determination is made that cursor  742  has been positioned over end control  720   c  for the predetermined period of time, computer system  600  activates end control  720   c . Once end control  720   c  is activated, computer system  600  displays completion user interface  770  that indicates that the workout tracker has ended. 
       FIGS.  7 U- 7 AA  illustrate exemplary user interfaces for navigating a user interface using hand gestures and a moving cursor. In particular,  FIGS.  7 U- 7 AA  illustrate an exemplary scenario where computer system  600  enters the moving cursor operation mode in response to detecting a shake gesture (e.g., instead of activating moving cursor control  732   b  on menu  732  via one or more hand gestures, as described above in relation to  FIG.  7 N ).  FIG.  7 U  illustrates computer system  600  displaying clock user interface  710 , which includes a current time (e.g., 10:09). At  FIG.  7 W , computer system  600  detects that it is being (or has been) shaken (e.g., via one or more accelerometers and/or gyroscopes) (e.g.,  750   w ). At  FIG.  7 X , in response to detecting that computer system  600  is being (or has been) shaken, computer system  600  begins operating in a moving cursor mode (e.g., transitions from not operating in a moving cursor mode to operating in the moving cursor mode). In response to detecting that computer system  600  is being (or has been) shaken, computer system  600  displays cursor  742 . At  FIG.  7 Y , computer system  600  detects that computer system  600  is being tilted (e.g., moved) to the right (e.g.,  750   y ). At  FIG.  7 Y , in response to detecting that computer system  600  is being tilted to the right, computer system  600  moves cursor  742  to the right based on the amount of tilting and/or speed of the tilting being detected by computer system  600 . As illustrated in  FIG.  7 Y , cursor  742  is moved toward the right edge of clock user interface  710 . At  FIG.  7 Y , a determination is made that cursor  742  is positioned at (e.g., and/or near) the right edge of clock user interface  710 . As illustrated in  FIGS.  7 Z- 7 AA , because the determination is made that cursor  742  is positioned on the left edge of workout user interface  718 , computer system  600  displays an animation that slides clock user interface off the left edge (e.g., away from the edge that cursor  742  is positioned on) of display screen  602   c  and displays analog clock user interface  780  sliding on from the right of display screen  602   c  and moving towards the left edge of display screen  602   c.    
       FIGS.  8 A- 8 J  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
     In particular,  FIGS.  8 A- 8 J  illustrate an exemplary scenario where computer system  600  displays menu  732  in response to cursor  742  being located (e.g., displayed) over a user interface object (e.g., instead of activating the user interface object as described above in relation to  FIGS.  7 I- 7 U ).  FIG.  8 A  illustrates computer system  600  displaying clock user interface  810 , which includes application control  810   a - 810   d  (e.g., that, when activated, each cause computer system  600  to launch an application). At  FIG.  8 A , computer system  600  detects that it is being (or has been) shaken (e.g.,  850   a ) (e.g., using one or more techniques as described above in relation to  FIGS.  7 U- 7 AA ). At  FIG.  8 B , in response to detecting that computer system  600  is being (or has been) shaken, computer system  600  begins operating in a moving cursor mode and displays cursor  742  on clock user interface  810 . 
     At  FIG.  8 C , cursor  742  has been displayed at the same location (e.g., location that it was displayed in at  FIG.  8 B ) for a predetermined period of time. However, at  FIG.  8 C , computer system  600  does not display an animation of cursor  742  filling up because cursor  742  is not located at a location that corresponds to a user interface object (e.g., a selectable and/or a user interface object that can be activated and/or a user interface object that is activated when computer system  600  detects one or more inputs on the user interface object and, in some embodiments, when computer system is operating in a normal operation mode and/or not detecting hand gestures) (e.g., using one or more techniques described in relation to  FIGS.  7 I- 7 U ). At  FIG.  8 C , computer system  600  detects that it is being tilted downward (e.g.,  850   c ) (e.g., using one or more techniques described in relation to  FIGS.  7 I- 7 U ). As illustrated in  FIG.  8 D , in response detecting that computer system  600  is being tilted downward, computer system  600  moves cursor  742  over application icon  810   d.    
     As illustrated in  FIG.  8 E- 8 G , computer system  600  displays an animation cursor of indication  744  filling up cursor  742  over a period of time because cursor  742  is displayed over application icon  810   d  (e.g., a selectable user interface object) (e.g., using one or more techniques as discussed above in relation to  FIGS.  7 I- 7 U ). As illustrated in  FIG.  8 G , indication  744  has completely filled up cursor  742 . At  FIG.  8 G , a determination is made that cursor  742  has been displayed over a determination is made that cursor  742  has been positioned over application icon  810   d  for a predetermined period of time (e.g., 1-5 seconds). 
     As illustrated in  FIG.  8 H , because the determination is made that cursor  742  has been positioned over application icon  810   d  for a predetermined period of time, computer system  600  displays menu  732  (e.g., and, in some embodiments, selects application icon  810   d  and/or the location of application icon  810   d  (e.g., such that an operation can be performed using application icon  810   d  and/or the location of application icon  810   d ) without activating application icon  810   d ). In addition, at  FIG.  8 H , computer system  600  is displaying cursor  742  positioned over interaction control  732   c . In some embodiments, one or more settings control whether computer system  600  will activate a user interface object when the determination is made that cursor  742  has been positioned over the respective user interface object for a predetermined period of time, computer system  600  displays a menu when the determination is made that cursor  742  has been positioned over the respective user interface object for a predetermined period of time, or do both. In some embodiments, computer system  600  displays menu  732  in a position on the display that is further away from where cursor  742  was positioned over application icon  810   d  (as to not cover up the user interface object that cursor  742  was hovering over). 
     As illustrated in  FIG.  8 I , computer system  600  displays indication  744  that has filled up cursor  742  (e.g., using one or more techniques as discussed in relation to  FIGS.  8 E- 8 G ). At  FIG.  8 I , a determination is made that cursor  742  has been detected over interaction control  732   c  for a predetermined period of time. At  FIG.  8 J , because a determination is made that cursor  742  has been detected over cursor  742  for a predetermined period of time, computer system  600  activates interaction control  732   c . In response to the activation of interaction control  732   c , computer system  600  displays additional controls, which include tap control  832   a . Notably, when a determination is made that cursor  742  has been detected over a selectable user interface object for a predetermined time while menu  732  is displayed, computer system  600  activates the user interface object (and does not re-display menu  732 , irrespective of the one or more settings of computer system  600 ). 
     At  FIG.  8 J , computer system  600  displays cursor over tap control  832   a . In some embodiments, when a determination is made that cursor  742  has been detected over tap control  832   a , computer system  600  activates tap control  832   a . In some embodiments, in response to detecting activation of tap control  832   a , computer system  600  detects and/or performs an operation that would have been performed if a tap gesture was detected at the location that cursor  742  was displayed over that caused menu  732  to be displayed (e.g., in  FIGS.  8 G- 8 I ). For example, at  FIG.  8 J , in response to detecting activation of tap control  832   a , computer system  600  launches an application that corresponds to application icon  810   d  (e.g., the user interface of  FIG.  10 F ). In some embodiments, other gestures control can be displayed and activated, where computer system  600  performs an operation (e.g., a different operation that if a tap gesture had been detected) (e.g., a gesture that causes a clock face menu to be displayed, a gesture that causes the application icon to be moved from one location to another location on clock user interface  810 , a gesture that causes the application icon to be deleted from clock user interface  810 ) that would have been performed if the respective gesture (e.g., a long press gesture, a dragging gesture) was detected at the location that cursor  742  was displayed over that caused menu  732  to be displayed. 
       FIGS.  9 A- 9 H  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
     In particular,  FIGS.  9 A- 9 H  illustrate an exemplary scenario where computer system  600  navigates through a user interface in response to detecting hand gestures (e.g., using similar techniques as described above in relation to  FIGS.  7 A- 7 G ).  FIG.  9 A  illustrates computer system  600  displaying media user interface  910  while not operating in a hand gesture navigation mode. Media user interface  910  includes back control  910   a  (e.g., that, when activated, causes computer system  600  to display a previously displayed user interface), reverse control  910   b  (e.g., that, when activated, causes computer system  600  to be configured to playback a previous media item that is in a list of media items), pause control  910   c  (e.g., that, when activated, causes computer system  600  to pause the playback of a media item), forward control  910   d  (e.g., that, when activated, causes computer system  600  to be configured to playback a next media item that is in a list of media items), additional options control  910   e  (e.g., that, when activated, causes computer system  600  to display one or more additional controls that are not currently displayed in  FIG.  9 A ), queue control  910   f  (e.g., that, when activated, causes computer system  600  to display a list of queued media items), and connection control  910   g  (e.g., that, when activated, causes computer system  600  to display a user interface for connecting computer system  600  to one or more external computer systems). At  FIG.  9 A , computer system  600  detects double clench gesture  950   a.    
     At  FIG.  9 B , in response to detecting double clench gesture  950   a , computer system  600  begins operating in a hand gesture navigation mode (e.g., using one or more techniques as described above in relation to  FIGS.  7 D- 7 E ). As illustrated in  FIG.  9 B , in response to detecting double clench gesture  950   a , computer system  600  displays a focus indicator around forward control  910   d  (e.g., using one or more techniques as discussed above in relation to  FIG.  7 D ). In some embodiments, computer system  600  displays the focus indicator around a control that is different from and/or not forward control  910   d  (e.g., controls  910   a - 910   d  or  910   e - 910   g ) on media user interface  910  in response to detecting double clench gesture  950   a.    
     At  FIG.  9 B , computer system  600  detects double pinch gesture  950   b . As illustrated in  FIG.  9 C , in response to detecting double pinch gesture  950   b , computer system  600  moves the focus indicator to the left, such that the focus indicator is displayed around pause control  910   c  and not displayed around forward control  910   d . At  FIG.  9 C , in response to detecting double pinch gesture  950   b , computer system  600  moves the focus indicator around a control that computer system  600  has determined to be a previous control on media user interface  910  in relation to forward control  910   d . In some embodiments, computer system  600  determines a previous control by identifying a control that is in the direction on media user interface  910  that travels from the location of forward control  910   d  (e.g., the previous control that the focus indicator was around) towards a starting row on media user interface  910  (e.g., a position on a row near and/or at the top of media user interface  910  and/or a position on a row that has a selectable user interface object (e.g., a control) that is furthest to the left/right and near the top of media user interface  910 ). In some embodiments, at  FIG.  9 C , pause control  910   c  is determined to be the previous control to forward control  910   d  because pause control  910   c  is adjacent (e.g., next to or next to without another control being in between the two controls) to forward control  910   d  and is closer to the starting row of media user interface  910  than forward control  910   d  (or, in some embodiments, any other of the other adjacent controls (e.g., queue control  910   f , additional options control  910   e )). At  FIG.  9 C , computer system  600  detects clench gesture  950   c.    
     At  FIG.  9 D , in response to detecting clench gesture  950   c , computer system  600  activates pause control  910   c  and pauses the playback of media (e.g., “WHAT MATTERS” by “POP STARS”). As illustrated in  FIG.  9 D , in response to detecting clench gesture  950   c , pause control  910   c  is replaced with play control  910   h  (e.g., that, when activated, initiates the playback of a media item). As illustrated in  FIG.  9 D , in response to detecting clench gesture  950   c , computer system  600  maintains the focus indicator in the same position on media user interface  910 . Thus, in some embodiments, computer system  600  does not move the focus control when detecting clench gesture  950   c  and/or when activating a control in response to detecting a hand gesture, irrespective of whether the control is replaced with another control. At  FIG.  9 E , computer system  600  detects pinch gesture  950   e.    
     As illustrated in  FIG.  9 F , in response to detecting pinch gesture  950   e , computer system  600  moves the focus indicator to the right, such that the focus indicator is displayed around forward control  910   d  and not displayed around play control  910   h . At  FIG.  9 F , in response to detecting pinch gesture  950   e , computer system  600  moves the focus indicator to around a control that computer system  600  has determined to be a next control on media user interface  910  in relation to play control  910   h . In some embodiments, computer system  600  determines a next control by identifying a control that is in the direction on media user interface  910  that travels from the location of forward control  910   d  (e.g., the previous control that the focus indicator was around) towards an ending row on media user interface  910  (e.g., a position on a row near and/or at the bottom of media user interface  910  and/or a position on a row that has a selectable user interface object (e.g., a control) that is furthest to the left/right and near the top of media user interface  910 ). In some embodiments, at  FIG.  9 F , forward control  910   d  is determined to be the next control to play control  910   h  because forward control  910   d  is adjacent (e.g., next to or next to without another control being in between the two controls) to forward control  910   d  and is closer to the starting row of media user interface  910  than play control  910   h.    
     Notably, double pinch gesture  950   b  of  FIG.  9 B  includes multiple instances of pinch gesture  950   e  of  FIG.  9 E . In addition, computer system  600  performs an opposing operation (e.g., navigating to a previous control) in response to detecting double pinch gesture  950   b  to the operation that computer system  600  performed in response to detecting pinch gesture  950   e . Thus, in some embodiments, computer system  600  performs opposing operations in response to detecting gestures that include multiple instances of each other. In some embodiments, the opposing gestures help the user navigate the user interfaces more easily because of the connectedness (e.g., similarity between) of the different gestures. Turning back to  FIG.  9 F , computer system  600  detects pinch gesture  950   f.    
     As illustrated in  FIG.  9 G , in response to detecting pinch gesture  950   f , computer system  600  moves the focus indicator downward, such that the focus indicator is displayed around additional options control  910   e  and not displayed around forward control  910   d . Here, computer system  600  moves the focus indicator downward because additional options control  910   e  is the next control. At  FIG.  9 G , computer system  600  does not display the focus indicator around connection control  910   g  because connection control  910   g  is not adjacent to forward control  910   d  (e.g., so connection control  910   g  is not determined to be the next control). In some embodiments, computer system  600  moves the focus around a user interface in a pattern that is based on the particular layout of the controls on the particular user interface. Looking back at  FIG.  9 A , in some embodiments, computer system  600  moves focus indicator around media user interface  910  in the identifying order of the controls ( 910   a ,  910   b ,  910   c ,  910   d ,  910   e ,  910   f , and  910   g , consecutively (or in reverse)). In some embodiments, when the focus indicator is around the last control (e.g.,  910   g ), computer system  600  moves the focus indicator around the first control (e.g.,  910   a ) in response to detecting a pinch gesture (or a gesture to move the next control). In some embodiments, when the focus indicator is around the first control (e.g.,  910   a ), computer system  600  moves the focus indicator around the last control (e.g.,  910   g ) in response to detecting a double pinch gesture (or a gesture to move the previous control). Turning back to  FIG.  9 G , computer system  600  detects clench gesture  950   g  while the focus indicator is around additional options control  910   e.    
     As illustrated in  FIG.  9 H , in response to detecting clench gesture  950   g , computer system  600  displays additional options user interface  920  and ceases to display media user interface  910 . As illustrated in  FIG.  9 H , in response to detecting clench gesture  950   g , computer system  600  displays a focus indicator around a control (e.g., a control at a position on the beginning row) of additional options user interface  920 . In some embodiments, in response to detecting one or more hand gestures to move the focus indicator around additional options user interface  920  (e.g., pinch and/or double pinch gestures), computer system  600  moves the focus indicator around different controls included in additional options user interface  920 . In some embodiments, computer system  600  moves the focus indicator around different controls included in additional options user interface  920  in a different pattern (e.g., vertical pattern) from the pattern (e.g., snaking pattern) that computer system  600  moved the focus indicator around the controls included media user interface  910  (e.g., as described above in relations to  FIGS.  9 A- 9 G ). 
       FIGS.  10 A- 10 F  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
     In particular,  FIGS.  10 A- 10 F  illustrate an exemplary scenario where computer system  600  navigates through a user interface in response to detecting hand gestures (e.g., using similar techniques as described above in relation to  FIGS.  7 A- 7 G ).  FIG.  10 A  illustrates computer system  600  displaying media user interface  1010  while not operating in a hand gesture navigation mode. Media user interface  1010  includes application icons  1010   a - 1010   d  (e.g., that, when activated, causes computer system  600  to display a user interface for the respective application icon that was activated). At  FIG.  10 A , computer system  600  is operating in a hand navigation operation mode (e.g., as discussed above in relation to  FIGS.  7 A- 7 G and  9 A- 9 H ). In some embodiments, computer system  600  navigates through media user interface  1010  using one or more techniques described above in relation to  FIGS.  7 A- 7 G and  9 A- 9 H . At  FIG.  10 B , computer system  600  detects double clench gesture  1050   b.    
     As illustrated in  FIG.  10 C , in response to detecting double clench gesture  1050   b , computer system  600  displays menu  732  that includes controls  732   a - 732   d  (e.g., as discussed above in relation to  FIG.  7 D ). Menu  732  includes control identifier  708  (“DIGITAL CROWN”) that identifies the control that is currently in focused (e.g., the black box around digital hardware operation control  732   a  in  FIG.  10 C ). As illustrated in  FIG.  10 C , computer system  600  displays focus indicators around both digital hardware operation control  732   a  and application icon  1010   c  because application icon  1010   c  was selected before double clench gesture  1050   b  was detected and/or computer system  600  can perform an operation at the location of application icon  1010   c  (e.g., activation of application icon  1010   c , as discussed above in relation to  FIG.  8 J ). At  FIG.  10 C , computer system detects double clench gesture  1050   c.    
     As illustrated in  FIG.  10 D , in response to detecting double clench gesture  1050   c , computer system  600  ceases to display menu  732  (e.g., while computer system  600  has continued to operate in the hand gesture navigation mode). At  FIG.  10 D , computer system  600  detects pinch gesture  1050   d . As illustrated in  FIG.  10 E , in response to detecting pinch gesture  1050   d , computer system  600  moves the focus indicator downward and to the left, such that the focus indicator is displayed around application icon  1010   d  and not displayed around application icon  1010   c . Computer system  600  displays the focus indicator around application icon  1010   d  because a determination was made that application icon  1010   d  was the next control (e.g., in response to detecting pinch gesture  1050   d ). In some embodiments, this determination was made using one or more techniques discussed above in relation to  FIGS.  9 A- 9 H . At  FIG.  10 E , computer system  600  detects clench gesture  1050   e . At  FIG.  10 F , in response to detecting clench gesture  1050   e , computer system  600  activates application icon  1010   d  and displays an application (e.g., breather application) that corresponds to application icon  1010   d  (e.g., a breathing application icon). 
       FIGS.  11 A- 11 H  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . In particular,  FIGS.  11 A- 11 H  illustrate an exemplary scenario where computer system  600  automatically scrolls through a user interface and performs different operations in response to detecting one or more hand gestures. In some embodiments, computer system  600  automatically scrolls through the user interface when the computer system is operating in a digital hardware operation mode (e.g., a hand gesture navigation mode) using one or more techniques as described in relation to  FIGS.  11 A- 11 H . In some embodiments, computer system  600  begins operating in the digital hardware operation mode in response to activation of digital hardware operation control  732   a . In some embodiments, computer system  600  automatically scrolls through the user interface in a similar and/or performs the same operation(s) as the operation(s) that are performed in response to computer system  600  detecting an input (e.g., a rotatable input) on input mechanism. In some embodiments, computer system  600  automatically scrolls through the user interface when the computer system is operating in an automatic scrolling mode (e.g., as discussed below in relation to  1412 ). 
       FIG.  11 A  illustrates computer system  600  displaying text message user interface  1110 . Text message user interface  1110  includes text message region  1120  and one or more controls that include animated image control  1110   a . As illustrated in  FIG.  11 A , text message region  1120  includes text message  1120   a  (“HEY, WHERE ARE YOU?”). As illustrated in  FIG.  11 A , computer system  600  is displaying a focus indicator around animated image control  1110   a , which is displayed at the bottom of text message user interface  1110 . At  FIG.  11 A , computer system  600  detects double clench gesture  1150   a.    
     As illustrated in  FIG.  11 B , in response to detecting double clench gesture  1150   a , computer system  600  displays menu  732  that includes digital hardware operation control  732   a . At  FIG.  11 B , computer system  600  displays menu  732  at the top of text message user interface  1110 . In some embodiments, computer system  600  displays menu  732  at the top of text message user interface  1110  because the focus indicator was displayed around animated image control  1110   a , and animated image control  1110   a  is displayed at the bottom of text message user interface  1110 . In some embodiments, computer system  600  displays menu  732  at the bottom (or another area of a user interface) in response to a determination that a selected control (e.g., a control with a focus indicator around it) is not displayed at the bottom of media user interface  1110 . At  FIG.  11 B , computer system  600  detects double clench gesture  1150   b  while the focus indicator is displayed around digital hardware operation control  732   a.    
     As illustrated in  FIG.  11 C , in response to detecting double clench gesture  1150   b , computer system  600  begins operating in a digital hardware operation mode (e.g., and/or an automatic scrolling mode). While operating in the digital hardware operation mode, computer system  600  performs operations as if one or more inputs (e.g., rotational inputs, press inputs, sliding inputs) were received at an input mechanism of computer system  600 . Sometime after displaying the user interface of  FIG.  11 C , computer system  600  performs an operation that is consistent with one or more inputs being detected on input mechanism  602   a  without detecting an input and/or hand gesture (e.g., hand  622  being in the neutral position). As illustrated in  FIG.  11 D , when performing the operation, computer system  600  moves the focus indicator from being around animated image control  1110   a  to be around language control  1110   b  (e.g., without an input being detected on input mechanism  602   a ), which is an operation that is consistent with an input being detected on input mechanism  602   a . Sometime after displaying the user interface of  FIG.  11 D , computer system  600  performs another operation that is consistent with one or more inputs being detected on input mechanism  602   a  without detecting an input and/or hand gesture (e.g., hand  622  being in the neutral position). As illustrated in  FIG.  11 E , when performing the operation, computer system  600  scrolls text message user interface  1110  and moves the focus indicator from being around language control  1110   b  to be around reply control  1110   c . Sometime after displaying the user interface of  FIG.  11 E , computer system  600  performs another operation that is consistent with one or more inputs being detected on input mechanism  602   a  without detecting an input and/or hand gesture (e.g., hand  622  being in the neutral position), computer system  600  scrolls text message user interface  1110  (e.g., a new control is displayed) and moves the focus indicator from being around reply control  1110   c  to be around reply control  1110   e . At  FIG.  11 F , computer system  600  detects pinch gesture  1150   f  while the focus indicator is displayed around reply control  1110   e . As illustrated in  FIG.  11 G , in response to detecting pinch gesture  1150   f , computer system  600  ceases to automatically perform operations that are consistent with one or more inputs being detected on input mechanism  602   a  (e.g., and/or pausing the scrolling). In some embodiments, in response to detecting an additional pinch gesture, computer system  600  resumes performing operations that are consistent with one or more inputs being detected on input mechanism  602   a.    
     At  FIG.  11 G , computer system  600  detects clench gesture  1150   g  while the focus indicator is displayed around reply control  1110   e . As illustrated in  FIG.  11 G , in response to detecting clench gesture  1150   g , reply control  1110   e  is activated. At  FIG.  11 G , in response to detecting clench gesture  1150   g , computer system  600  inserts reply message  1120   b  (“ON MY WAY”) that corresponds to reply control  1110   e  in text message region  1120 . In some embodiments, computer system  600  sends reply message  1120   b  to one or more external computer systems that are a part of a text messaging conversation. 
       FIGS.  12 A- 12 J  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
     In particular,  FIGS.  12 A- 12 J  illustrate an exemplary scenario where computer system  600  automatically scrolls through a user interface and performs different operations in response to detecting one or more hand gestures. In some embodiments, computer system  600  automatically scrolls through the user interface when the computer system is operating in a digital hardware operation mode (e.g., a hand gesture navigation mode) using one or more techniques as described in relation to  FIGS.  12 A- 12 J . In some embodiments, computer system  600  begins operating in the digital hardware operation mode in response to activation of digital hardware operation control  732   a . In some embodiments, computer system  600  automatically scrolls through the user interface in a similar and/or performs the same operation(s) as the operation(s) that are performed in response to computer system  600  detecting an input (e.g., a rotatable input) on input mechanism. In some embodiments, computer system  600  automatically scrolls through the user interface when the computer system is operating in an automatic scrolling mode (e.g., as discussed below in relation to  1412 ). 
       FIG.  12 A  illustrates computer system  600  displaying clock face user interface  1210 . Clock face user interface  1210  includes selectable controls  1210   a - 1210   e . At  FIG.  12 A , computer system  600  is operating in an automatic scrolling mode. As illustrated in  FIGS.  12 A- 12 C , computer system  600  automatically (e.g., as indicated by hand  622  being in the neutral position) moves the focus indicator between selectable controls  1210   a - 1210   c  (e.g., without computer system  600  detecting an input) (e.g., at a first speed). At  FIG.  12 C , computer system  600  detects pinch gesture  1250   c  while focus indicator is displayed around selectable control  1210   c . As illustrated in  FIG.  12 D , in response to detecting pinch gesture  1250   c , computer system  600  stops automatically moving the focus indicator between selectable controls and continues to display the focus indicator around selectable control  1210   c  (e.g., as indicated by hand  622  being in the neutral position). At  FIG.  12 E , computer system  600  detects pinch gesture  1250   e  while focus indicator is displayed around selectable control  1210   c . As illustrated in  FIG.  12 F- 12 G , in response to detecting pinch gesture  1250   e , computer system  600  resumes moving the focus indicator (e.g., displaying the focus indicator around selectable control  1210   d  and, then around selectable control  1210   e ). 
     At  FIG.  12 H , computer system  600  moves focus indicator to the left, such that focus indicator is displayed around selectable control  1210   d  and not displayed around  1210   e . At  FIG.  12 H , computer system  600  moves the focus indicator from selectable control  1210   e  to selectable control  1210   d  because  1210   e  is determined to be the last selectable control on clock face user interface  1210 . Thus, at  FIG.  12 H , computer system  600  reverses the direction of movement of the focus indicator around selectable user interface objects of clock face user interface  1210 . In some embodiments, computer system  600  displays the focus indicator around selectable control  1210   c  when a predetermined amount of time has passed. At  FIG.  12 H , computer system  600  detects double pinch gesture  1250   h . At  FIG.  12 G , in response to detecting double pinch gesture  1250   h , computer system  600  reverses the direction of the movement of focus indicator around selectable user interface objects of clock face user interface  1210 . As illustrated in  FIG.  12 I , in response to detecting double pinch gesture  1250   h , computer system  600  displays the focus indicator around selectable control  1210   e  (e.g., instead of displaying the focus indicator around selectable control  1210   c  to which computer system  600  would have displayed the focus indicator around if double pinch gesture  1250   h  was not detected). At  FIG.  12 I , computer system  600  detects clench gesture  1250   i  while the focus indicator is displayed around selectable control  1210   e . As illustrated in  FIG.  12 J , in response to detecting clench gesture  1250   j , computer system  600  activates selectable control  1210   e . As illustrated in  FIG.  12 J , in response to detecting clench gesture  1250   j , computer system  600  displays calendar application user interface  1220 , which the user interface of an application that corresponds to selectable control  1210   e.    
       FIGS.  13 A- 13 G  illustrate exemplary user interfaces for navigating user interfaces using hand gestures, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  15 - 16   . 
     In particular,  FIGS.  13 A- 13 G  illustrate one or more exemplary settings for controlling one or more hand gesture navigations modes (e.g., as described above in relation to  FIGS.  7 A- 7 AA ,  FIGS.  8 A- 8 J ,  FIGS.  9 A- 9 H ,  FIGS.  10 A- 10 F ,  FIGS.  11 A- 11 H , and  FIGS.  12 A- 12 J ).  FIG.  13 A  illustrates computer system  600  displaying one or more settings that include accessibility setting controls  1312   a ,  1312   b , and  1312   c . In some embodiments, in response to detecting an input on accessibility setting control  1312   a , computer system  600  displays one or more of accessibility settings  1322   a - 1322   f  (e.g., as illustrated in  FIG.  13 B ). 
     As illustrated in  FIG.  13 B , accessibility settings  1312   a - 1312   f  include hand gesture navigation control  1322   h . In some embodiments, when hand gesture navigation control  1322   h  is off (e.g., inactive), computer system  600  does not perform operations in response to detecting hand gestures. In some embodiments, when hand gesture navigation control  1322   h  is on (e.g., active), computer system  600  performs operations in response to detecting hand gestures. In some embodiments, in response to detecting a gesture directed to hand gesture navigation control  1322   h , computer system  600  displays the user interface of  FIG.  13 C . 
     As illustrated in  FIG.  13 C , computer system  600  displays hand gesture navigation controls  1314   a - 1314   h . The hand gesture navigation controls include main setting control  1314   a , hand gesture control  1314   b , moving cursor control  1314   c , movement style control  1314   d , and one or more appearance settings controls  1314   e - 1314   g , and confirm with hand gestures controls  1314   h . In response to detecting an input directed to main setting control  1314   a , computer system  600  turns the hand gesture navigation mode on/off (e.g., as described above in relation to hand gesture navigation control  1322   h ). In response to detecting an input directed to hand gesture control  1314   b , computer system  600  toggles hand gesture control  1314   b  on/off. When hand gesture control  1314   b  is on, computer system  600  is configured to perform one or more operations in response to detecting a hand gesture. When hand gesture control  1314   b  is off, computer system  600  is not configured to perform one or more operations in response to detecting a hand gesture. In response to detecting an input directed to moving cursor control  1314   c , computer system  600  toggles moving cursor control on/off. When moving cursor control  1314   c  is on, computer system  600  can be configured to operate in a moving cursor mode (e.g., as described above in relation to  FIGS.  7 I- 7 U  and  FIGS.  8 A- 8 J ). When moving cursor control  1314   c  is off, computer system  600  cannot be configured to operate in a moving cursor mode (e.g., in response to a shake gesture and/or in response to detecting an input on moving cursor control  732   b  of menu  732  in  FIG.  7 N ). In response to detecting an input directed to movement style control  1314   d , computer system  600  toggles movement style control  1314   d  between different movement options. The different movement options include one or more of automatic movement and manual movement (e.g., of the focus indicator on a displayed user interface). In response to detecting an input directed to one or more appearance settings controls  1314   e - 1314   g , computer system  600  changes one or more appearances of menu  732  (e.g., as described in relation to  FIG.  7 N ), cursor  742  (e.g., as described in relation to  FIGS.  7 A- 7 AA ), and indication  744  (e.g., as described in relation to  FIGS.  7 A- 7 AA ), such as the color and/or controls of one or more user interfaces objects that are displayed. In response to an input directed to detecting confirm with hand gestures control  1314   h , computer system  600  toggles confirm with hand gestures control  1314   h  on/off. When confirm with hand gestures control  1314   h  is on, computer system  600  is configured to confirm one or more operations (e.g., a payment transaction) in response to detecting one or more hand gestures. When confirm with hand gestures control  1314   h  is off, computer system  600  is not configured to confirm one or more operations in response to detecting one or more hand gestures. 
     As illustrated in  FIG.  13 D , computer system  600  displays one or more setting controls (e.g., setting controls  1316   a - 1313   e ) for changing one or more operations that computer system  600  performs in response to detecting a respective hand gesture. In some embodiments, in response to detecting one or more gestures directed to learn control  1316   e , computer system  600  displays the user interface of  FIG.  13 E . 
     As illustrated in  FIG.  13 E , computer system  600  displays user interface  1318 . User interface  1318  can include one or more instructions (e.g., with graphical representations) that indicate how the user can perform one or more gestures. In some embodiments, at  FIG.  13 C , computer system  600  displays the user interface of  FIG.  13 F  in response to detecting a gesture directed to moving cursor control  1314   c . In some embodiments, while displaying user interface  1318 , computer system  600  will provide feedback as to whether a user has performed a gesture correctly and/or incorrectly during a learning mode session. 
     As illustrated in  FIG.  13 F , computer system  1300  displays one or more controls for controlling one or more aspect of a moving cursor mode, such as the sensitivity (e.g.,  1322   b ) (e.g., how and/or how much a moving cursor moves in response to detecting movement (e.g., tilt) of computer system  600 ), active time (e.g.,  1322   c ) (e.g., the predetermined amount of time that a moving cursor has to be located over a user interface object in order for an operation to be performed and/or the amount of time that the indication (e.g., indication  744  of  FIG.  7 N ) represents), movement tolerance (e.g.,  1322   d ) (e.g., how much movement that needs to be performed before indication  744  is reset and/or the animation ceases to be displayed after moving cursor has been moved from a location that corresponds to a user interface object), and dwell control (e.g.,  1322   e ) (e.g., the predetermined amount of time that a moving user has to be located over a user interface object in order for an operation to be performed and/or whether computer system can begin operation in the moving cursor mode via one or more shake inputs). At  FIG.  13 G , computer system  600  displays one or more settings for changing the color (e.g.,  1324   a - 1324   c ) of a moving cursor. 
       FIG.  14    illustrates multiple menu controls that can be displayed on menu  732  (e.g., as described above in relation to  FIG.  7 N ). Menu  732  can include a hierarchy of controls, such as the hierarchy of controls described in relation to  FIG.  14   . In some embodiments, in response to detecting input directed to interaction control  1410 , computer system  600  displays one or more of tap control gesture  1410   a  (e.g., as described above in relation to  832   a ), moving cursor control  1410   b  (e.g., as described above in relation to moving cursor control  732   b ), digital hardware operation control  1410  (e.g., as described above in relation to digital hardware operation  732   a ). In some embodiments, in response to detecting input directed to system control  1414 , computer system  600  displays one or more of icon grid  1414   a  (e.g., that, when activated, displays a grid that including multiple application icons), control center  1414   b  (e.g., that, when activated, displays one or more device controls, such as a Wi-Fi control for toggling a Wi-Fi setting, a Bluetooth control for toggling a Bluetooth setting, a mute control for toggling sound output on/or), settings  1414   c  (e.g., that, when activated, displays one or more settings for configured the computer system, as described above in relation to  FIGS.  13 A- 13 G ), and dock control  1414   d  (e.g., that, when activated, displays one or more controls for navigating to one or more applications (e.g., open applications and/or applications that are running in the background)). In some embodiments, in response to detecting input directed to additional options control  1416  (e.g.,  732   d ), computer system  600  displays wallet control  1416   a  (e.g., that, when activated, causes computer system  600  to display one or more user interface object for initiating a payment transaction), side button  1416   b  (e.g., that, when activated, causes computer system  600  to perform one or operations that are consistent with input mechanism  602   b  be pressed, such as turning computer system  600  off), and gesture mode  1416   c  (e.g., that, when activated, causes computer system  60  to begin operating in a gesture mode). In some embodiments, in response to detecting an input directed to auto-scroll control  1412 , computer system  600  begins operating in an auto-scrolling mode (e.g., as described above in relation to  FIGS.  11 A- 11 H  and  FIGS.  12 A- 12 J ). In some embodiments, in response to detecting an input directed to exit control  1418 , computer system  600  ceases to display menu  732  (e.g., as described above in relation to  FIG.  7 N ). In some embodiments, menu  732  includes one or more controls that are not shown in  FIG.  14   . In some embodiments, the controls of menu  732  are in a different hierarchy than the one described in  FIG.  14   . 
       FIG.  15    is a flow diagram illustrating a method for  1500  using a computer system in accordance with some embodiments. Method  1500  is performed at a computer system (e.g.,  100 ,  300 ,  500 ) (e.g., a wearable device (e.g., a smartwatch)) that is in communication with a display generation component (e.g., a display controller, a touch-sensitive display system) and an optical sensor (e.g., a hear rate sensor). In some embodiments, the computer system is in communication with one or more sensors (e.g., one or more biometric sensors (e.g., an optical sensor (e.g., a heart rate sensor), a camera), a gyroscope, an accelerometer)). In some embodiments, the computer system is in communication with one or more input devices (e.g., a touch-sensitive surface, a microphone). In some embodiments, the computer system is in communication with one or more output devices (e.g., one or more speakers, one or more microphones). Some operations in method  1500  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  1500  provides an intuitive way for navigating user interfaces using hand gestures. The method reduces the cognitive burden on a user for navigating user interfaces using hand gestures, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to navigate user interfaces faster and more efficiently conserves power and increases the time between battery charges. 
     The computer system displays ( 1502 ), via the display generation component, a user interface that includes a first user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ), a second user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ), a third user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ), and an indication (e.g., the focus indicator as discuss as being around  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) that (e.g., a visual indication (e.g., highlighting (e.g., a border of), displaying text, enlarging) the first user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) is selected (e.g., without indicating that the second user interface object and the third user interface object is selected). In some embodiments, the first user interface object, the second user interface object, and the third user interface object are different from each other. In some embodiments, the first user interface object is displayed between the second user interface object and the third user interface object. In some embodiments, the first user interface object, the second user interface object, and the third user interface object are different user interface objects. 
     In some embodiments, while displaying the user interface that includes the first user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) (e.g., and while the computer system is in a first operation mode (e.g., first accessibility mode)), the second user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ), the third user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ), and the indication (e.g., the focus indicator as discuss as being around  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) that the first user interface object is selected, the computer system detects ( 1504 ), via (e.g., using) at least the optical sensor (e.g., and/or one or more other sensors, such as a gyroscope, an accelerometer), a hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) (e.g., a first hand gesture) (e.g., that does not contact the device (e.g., not directed towards an object on the user interface and/or any device that is in communication with the device)) (e.g., a hand gesture that is not detected by one or more cameras of the device) (e.g., a hand gesture that occurs while the wrist of a user is located at a single location and/or does not move, a hand gesture that is detected while the computer system is being worn on a wrist (e.g., a wrist of a user)). 
     In some embodiments, in response to ( 1506 ), via at least the optical sensor, the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) (and while displaying the user interface that includes the first user interface object, the second user interface object, the third user interface object) (e.g., and while the computer system is operating in a first operation mode) and in accordance with a determination that the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) is a first type of gesture (e.g.,  610 ,  620 ,  630 ,  640 ,  650 ) (e.g., type of hand gesture) (e.g., a finger tap/pinch gesture (e.g., a gesture where two or more fingers touch each other)) (and, in some embodiments, the first type of gesture is a non-finger tap/pinch gesture (e.g., a clench gesture (e.g., a gesture that makes a fist), a multi-clench gesture (e.g., a gesture that includes multiple clench gestures), a finger spreading gesture (e.g., a gesture where one or more fingers do not touch portion of hand), a multi-finger spreading gesture (e.g., a gesture that include multiple spreading gestures), and/or any combination thereof), the computer system displays ( 1508 ), via the display generation component, an indication (e.g., the focus indicator as discuss as being around  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) that (e.g., a visual indication (e.g., highlighting (e.g., a border of), displaying text, enlarging) the second user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) (e.g., new user interface object that is selected) is selected (e.g., ceasing to display the indication that the first user interface object is selected and/or without displaying the indication that the third user interface object is selected) (e.g., without indicating that the first user interface object and the third user interface object is selected). In some embodiments, the indication that the second user interface object was not previously displayed before the first indication that the first user interface object was displayed. In some embodiments, in accordance with a determination that the hand gesture is the first type of gesture, the computer system moves an indication from (e.g., from being displayed around, adjacent to (e.g., above, below, next to)) the first user interface object (e.g., the indication that the first user interface object is selected) to (e.g., to being displayed around, adjacent to (e.g., above, below, next to)) the second user interface object (e.g., the indication that the second user interface object is selected). 
     In some embodiments, in response to ( 1506 ), via at least the optical sensor, the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) (and while displaying the user interface that includes the first user interface object, the second user interface object, the third user interface object) (e.g., and while the computer system is operating in a first operation mode) and in accordance with a determination that the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) is a second type of gesture (e.g.,  610 ,  620 ,  630 ,  640 ,  650 ) (e.g., type of hand gesture) (e.g., a multi-finger tap/pinch gesture (e.g., a gesture where two or more fingers touch each other multiple times)) (and, in some embodiments, the first type of gesture is a non-finger tap/pinch gesture (e.g., a clench gesture (e.g., a gesture that makes a fist), a multi-clench gesture (e.g., a gesture that includes multiple clench gestures), a finger spreading gesture (e.g., a gesture where one or more fingers do not touch portion of hand), a multi-finger spreading gesture (e.g., a gesture that include multiple spreading gestures), and/or any combination thereof) that is different from the first type of gesture, the computer system displays ( 1510 ), via the display generation component, an indication (e.g., the focus indicator as discuss as being around  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) that (e.g., a visual indication (e.g., highlighting (e.g., a border of), displaying text, enlarging) the third user interface object (e.g.,  712   a - 712   b ,  910   a - 910   h , or  1010   a - 1010   d ) (e.g., a previous user interface object that was selected) is selected (e.g., without indicating that the first user interface object and the second user interface object is selected) (e.g., ceasing to display the indication that the first user interface object is selected and/or without displaying the indication that the second user interface object is selected). In some embodiments, the indication that the third user interface object was previously displayed before the first indication that the first user interface object was displayed. In some embodiments, in accordance with a determination that the hand gesture is the second type of gesture, the computer system moves an indication from (e.g., from being displayed around, adjacent to (e.g., above, below, next to)) the first user interface object (e.g., the indication that the first user interface object is selected) to (e.g., to being displayed around, adjacent to (e.g., above, below, next to)) the third user interface object (e.g., the indication that the second user interface object is selected). In some embodiments, at least two of the indication that the first user interface object is selected, the indication that the second user interface object is selected, and/or the indication the third user interface object is selected are different sizes. Choosing whether to display an indication that the second user interface object is selected or to display an indication that the third user interface object is selected based on the type of hand gesture that is detected provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) is detected based on heart rate data that is determined using data detected via the optical sensor. In some embodiments, the second type of gesture (e.g.,  630  or  650 ) is a type of gesture that is multiple instances (e.g., multiple finger taps/pinches, multiple finger spreading gestures, and/or multiple clench gestures) of the first type of gesture (e.g.,  620  or  640 ). In some embodiments, the second type of gesture includes at least one instance of the first type of gesture. Choosing whether to display an indication that the second user interface object is selected or to display an indication that the third user interface object is selected based on the type of hand gesture that is detected, where the second type of gesture is a type of gesture that is multiple instances of the first type of gesture, provides the user with more control of the system and helps the user navigate the user interface to perform a similar action differently (e.g., selecting an object to the right vs. selecting an object to the left) using similar hand gestures (e.g., where one hand gesture includes the other hand gesture) without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, in response to detecting, via at least the optical sensor, the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) and in accordance with a determination that the hand gesture is a third type of gesture (e.g.,  620 ,  630 ,  640 , or  650 ) (e.g., type of hand gesture) that is different from the first type of gesture and the second type of gesture, the computer system performs (e.g., via the display generation component) an operation (e.g., an action) corresponding to selection of the first user interface object (e.g., selecting a play/pause button, selecting an interaction on the menu, selecting a cancel button, selecting an answer/decline button for an incoming phone call) (e.g., without displaying a menu that includes one or more selectable options). In some embodiments, in response to detecting, via at least the optical sensor, the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) and in accordance with a determination that the hand gesture is a fourth type of gesture (e.g.,  620 ,  630 ,  640 , or  650 ) (e.g., type of hand gesture) that is different from the first type of gesture, the second type of gesture, and the third type of gesture, the computer system displays, via the display generation component, a menu that includes one or more selectable options (e.g., as described below in relation to method  1600 ) (e.g., without performing the option corresponding to selection of the first user interface object). Choosing whether to perform an operation corresponding to selection of the first user interface object or display a menu that includes one or more selectable options based on the type of hand gesture that is detected provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, before detecting the hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ), the computer system (e.g.,  600 ) is in a first operation mode (e.g., an operation mode where the computer system performs the operation (e.g., operation) described above (e.g., as described above in relation to  FIGS.  7 A- 7 I ) in response to detecting one or more of the first type, second type, third type, and/or fourth type of gesture). In some embodiments, as a part of performing the operation corresponding to selection of the first user interface object (e.g.,  1412  or  736   a ) (e.g., as described above in relation to  FIGS.  11 A- 11 H and  12 A- 12 J ), the computer system transitions the computer system from (e.g.,  600 ) the first operation mode to a second operation mode (e.g., as described above in relation to  FIGS.  7 I- 7 U ) (e.g., a mode where a cursor moves automatically across the display, a mode where the user interface is automatically scrolled in a direction (e.g., up, down, right, left, oblique), a mode where detection of one or more the first type, second type, third type, and/or fourth type of gestures cause the computer system to perform different operations than those perform when the computer system is operating in the first operation mode). 
     In some embodiments, while the computer system (e.g.,  600 ) is in the second operation mode, the computer system detects, via at least the optical sensor, a second hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ). In some embodiments, in response to detecting, via at least the optical sensor, the second hand gesture (e.g., while the computer system is in the second operation mode and not the first operation mode) and in accordance with a determination that the second hand gesture is the first type (e.g.,  620 ,  630 ,  640 , or  650 ) of gesture, the computer system toggles a first automatic scrolling operation between an active state (e.g., a resume state) and an inactive state (e.g., a paused state) (e.g., as discussed above in relation to  FIGS.  12 C- 12 E ) (e.g., without reversing the direction of the automatic scrolling operation) (e.g., an operation where one or more user interface objects are automatically selected (e.g., without user input) in a sequence) (e.g., toggling an automatic scrolling operation between an active state and an inactive state is a different operation than displaying an indication that the second user interface object is selected). In some embodiments, in accordance with a determination that the hand gesture is the first type of gesture and in accordance with a determination that a scrolling operation is in the inactive state (e.g., a paused state, a scrolling paused state, a scrolling off state), the computer system transitions the automatic scrolling operation from the inactive state to the active state (e.g., resumes the scrolling operation). In some embodiments, in accordance with a determination that the hand gesture is the second type of gesture and in accordance with a determination that a scrolling operation is in the active state (e.g., a scrolling on state, a resumed state), the computer system transitions the automatic scrolling operation from the active state to the inactive state (e.g., pauses the scrolling operation). In some embodiments, in accordance with a determination that the automatic scrolling operation is active, the computer system displays a notification that indicates that the automatic scrolling operation is active. In some embodiments, in accordance with a determination that the automatic scrolling operation is inactive, the computer system a notification that indicates that the automatic scrolling operation is inactive and/or ceases to display the notification that indicates that the automatic scrolling operation is active. In some embodiments, in response to detecting, via at least the optical sensor, the second hand gesture (e.g., while the computer system is in the second operation mode and not the first operation mode) and in accordance with a determination that the second hand gesture is the second type of gesture, the computer system reverses a first direction of the first automatic scrolling operation (e.g., without toggling the automatic scrolling operation between an active state and an inactive state) (e.g., reversing a first direction of the automatic scrolling operation is a different operation than displaying an indication that the third user interface object is selected). In some embodiments, as apart of reversing the direction of the automatic scrolling operation, the computer system selects the user interface objects in a reverse order in which the user interfaces were previously selected and/or reverse an interface being scrolling in a direction. Choosing whether to toggle a first automatic scrolling operation between an active state and an inactive state or reverse a first direction of the automatic scrolling operation based on the type of hand gesture that is detected provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, in response to detecting, via at least the optical sensor, the second hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ): in accordance with a determination that the second hand gesture is the third type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ), the computer system performs a second operation (e.g., changing a speed of the automatic scrolling operation); and in accordance with a determination that the second hand gesture is the fourth type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ), the computer system performs a third operation that is different from the second operation (e.g., selecting a user interface at the current location of a user interface object that was highlighted by the scrolling operation when the second hand gesture was detected, ending the automatic scrolling mode). Choosing whether to perform a first operation or a second operation based on the type of hand gesture that is detected provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, while the computer system (e.g.,  600 ) is in the second operation mode, the computer system performs a second automatic scrolling operation that scrolls a sequence of a plurality of interface objects in a second direction (e.g., as discussed above in relation to  FIGS.  12 G- 12 H ). In some embodiments, while performing the second automatic scrolling operation, the computer system detects an end of the sequence of the plurality of user interface objects (e.g., detecting that a scroll position is at or near the last user interface object in the sequence and/or detecting a boundary of the user interface) (e.g., as discussed above in relation to  FIGS.  12 G- 12 H ). In some embodiments, in response to detecting the end of the sequence of the plurality of user interface objects, the computer system performs a third automatic scrolling operation that scrolls the sequence of a plurality of interface objects in a third direction that is different from (e.g., opposite from) the second direction (e.g., as discussed above in relation to  FIGS.  12 G- 12 H ). Automatically performing a third automatic scrolling operation that scrolls the sequence of a plurality of interface objects in a third direction that is different from the second direction in response to detecting the end of the sequence of the plurality of user interface objects allows the computer system to provide the user with a method for automatically navigating the user interface without the user providing additional input to restart/reset the automatic navigation when the automatic navigation has cycled through the user interface objects on the user interface. 
     In some embodiments, in response to detecting, via at least the optical sensor, the second hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) and in accordance with a determination that the second hand gesture is the fourth type of gesture (e.g.,  610 ,  620 ,  630 ,  640  or  650 ), the computer system transitions the computer system from the second operation mode to a third operation mode (and/or ending/exiting the second operation mode). In some embodiments, the third operation mode is the first operation mode. Transitioning the computer system from the second operation mode to a third operation mode in accordance with a determination that the second hand gesture is the fourth type of gesture provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, in accordance with a determination that the second hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) is the first type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ), the computer system displays a notification (e.g.,  716 ) that indicates a state of the automatic scrolling operation (e.g., scrolling paused, scrolling stopped). Displaying a notification that indicates a state of the automatic scrolling operation in accordance with a determination that the second hand gesture is the first type of gesture provides the user with visual feedback that an operation has been performed in response to a hand gesture being detected, which can prevent the user from mistakenly performing multiple gesture that can cause the computer system to perform unnecessary operations and/or unintended operations. 
     In some embodiments, the third type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ) is a type of gesture that is multiple instances (e.g., multiple finger taps/pinches, multiple finger spreading gestures, and/or multiple clench gestures) of the fourth type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ). In some embodiments, the third type of gesture includes at least one instance of the fourth type of gesture. In some embodiments, the fourth type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ) does not include multiple instance of the first type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ) (and/or the second type of gesture) and the third type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ) does not include multiple instances of the second type of gesture (e.g.,  610 ,  620 ,  630 ,  640 , or  650 ) (and/or the first type of gesture) (e.g., as discussed above in relation to  FIG.  6   ). In some embodiments, the fourth type of gesture does not include the first type of gesture and/or the second type of gesture. In some embodiments, the third type of gesture does not include the first type of gesture and/or the second type of gesture. 
     In some embodiments, in response to detecting, via at least the optical sensor, the second hand gesture (e.g.,  750   e ,  750   f ,  750   i ,  750   l ,  750   m ,  750   n ,  950   a ,  950   b ,  950   c ,  950   e ,  950   f ,  950   g ,  1050   b ,  1050   c ,  1050   d , or  1050   e ) and in accordance with a determination that a notification (e.g., a notification that corresponds to a phone call, an e-mail, a text message, a voice-mail message) was received within a threshold period of time and in accordance with a determination that the second hand gesture is the fourth type of gesture, the computer system performs an action related to the notification (e.g., answer the phone call, respond/open a text message and/or e-mail that corresponds to the notification, play a voice-mail message) (e.g., as discussed above in relation to  FIG.  7 H ). Performing an action related to the notification in accordance with a determination that a notification was received within a threshold period of time and in accordance with a determination that the second hand gesture is the fourth type provides the user with more control of the system and helps the user navigate the user interface (e.g., cause the computer system to perform an action related to the notification) without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, the one or more selectable options (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) includes a first selectable user interface object (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) for changing operations that one or more hand gestures can cause to the computer system to perform. In some embodiments, selection of the first selectable user interface objects causes the computer system to display a plurality of settings. In some embodiments, each setting controls an operation that the one or more hand gestures can cause the computer system to perform when the one or more hand gestures are detected by the computer system (e.g., as discussed above in relation to  FIGS.  8 A- 8 J ), Displaying a menu that includes a first selectable user interface object for changing what operations that one or more hand gestures can cause to the computer system to perform allows the computer system to provide the user with an option to perform an operation without requiring more complex hand gestures, which reduces the number of hand gestures that are used to perform the operation, and allows the user to customize the hand gestures that causes an operation to be performed. 
     In some embodiments, the one or more selectable options (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) includes a second selectable option for transitioning the computer system to a fourth operation mode and a third selectable option for transitioning the computer system to a fifth operation mode that is different from the fourth operation mode. In some embodiments, selection of the second selectable option (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) causes the computer system to transition to the fourth operation mode (e.g., an automatic scrolling mode, a cursor mode (e.g., as discussed herein in relation to method  1600 ). In some embodiments, selection of the third selectable option (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) causes the computer system to transition to the fifth operation mode (e.g., an automatic scrolling mode, a cursor mode (e.g., as discussed herein in relation to method  1600 ). Displaying a menu that includes the second selectable option for transitioning the computer system to a fourth operation mode and the third selectable option for transitioning the computer system to a fifth operation mode that is different from the fourth operation mode provides the user with more control over the computer system by allowing the user to cause the computer system to transitioned to different operation modes (e.g., without providing more complex hand gestures) and also reduces the number of hand gestures that are used to perform the operation. 
     In some embodiments, the one or more selectable options (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) include a fourth selectable option (e.g.,  1416 ) for displaying one or more additional selectable options (e.g., an option that corresponds to an option to perform an operation that corresponds to an operation that is performed when an input is detected at the location of the selectable user interface object (e.g., second location); an option to perform operation, such as turning on/off the computer system, displaying a different menu and/or user interface; an option that corresponds to an operation that is perform in response to detecting an input via one or more input devices in communication with the computer system). In some embodiments, selection of the fourth selectable option causes the computer system (e.g.,  600 ) to display the one or more additional selectable options (e.g., that, when selected, each cause the computer system to perform one or more operations (e.g., different operations)) that were not previously displayed before selection of the fourth selectable option. In some embodiments, in response to detecting of the fourth selectable option, the computer system ceases to display one or more selectable options that were displayed before selection of the fourth selectable option was detected. Displaying a menu that includes fourth selectable option for displaying one or more additional options provides the user with more control over the computer system by allowing the user to choose to display additional selectable options that were not previously displayed, reduces the number of hand gestures that are used to perform additional operations, and reduces the number of selectable user interface options that are displayed when the menu is initially displayed, which de-clutters the user interface. 
     In some embodiments, the menu is displayed: in accordance with a determination that a respective user interface object (e.g., a user interface object that is selected, a user interface object that is surrounded by a focus indicator) is at a first location on the user interface, at the first location (e.g., as discussed above in relation to  FIG.  11 B ); and in accordance with a determination that the respective user interface object is not at the first location on the user interface, at a second location that is different from the first location (e.g., as discussed above in relation to  FIG.  11 B ). Automatically choosing to display the menu at a location based on where a respective user interface object is displayed allows the computer system to avoid displaying the menu at a location of a user interface object that could be of interest to the user (e.g., a selected user interface object) and also reduces the number of inputs that a user would need to make to move the menu from impacting the display of the user interface object. 
     In some embodiments, while displaying a third menu (e.g.,  732 ) that includes one or more selectable options (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ) (e.g., the menu that includes the one or more selectable options, the second menu that includes one or more selectable options), the computer system detects, via at least the optical sensor, a third hand gesture (e.g., as discussed above in relation to  FIGS.  10 A- 10 E ). In some embodiments, in response to detecting, via at least the optical sensor, the third hand gesture (e.g., as discussed above in relation to  FIGS.  10 A- 10 E ) and in accordance with a determination that the third hand gesture is the fourth type of gesture, the computer system ceases to display the third menu that includes the one or more selectable options. Ceasing to display the menu that includes the one or more selectable options in accordance with a determination that the third hand gesture is the fourth type of gesture provides the user with more control of the system and helps the user navigate the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, after displaying the user interface that includes the first user interface object (e.g.,  732   a - 732   d ,  832   a , or  1410 - 1418 ), the computer system detects, via at least the optical sensor, a fourth hand gesture. In some embodiments, in response to detecting, via at least the optical sensor, the fourth hand gesture and in accordance with a determination that the fourth hand gesture is a fifth type of gesture (e.g., and, in some embodiments, the fifth type of gesture is the same gesture as the fourth type of gesture) that is different from the first type of gesture and the second type of gesture (and/or the first type of gesture), the computer system transitions the computer system from an inactive state (e.g., a sleep state, a hibernate state, a reduced power mode state, a state where the display generation component is less bright than the display generation component in the active state) to an active (e.g., a wake state, a full power state) state (or transitioning the computer system from the active state to the inactive state) (e.g., as discussed above in relation to  FIG.  14    (e.g.,  1416   b )). Transitioning the computer system from an inactive state to an active state in accordance with a determination that the fourth hand gesture is a fifth type of gesture provides the user with more control of the system without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, while displaying, via the display generation component, the indication that the second user interface object is selected, the computer system detects, via at least the optical sensor, a fifth hand gesture. In some embodiments, in response to detecting, via at least the optical sensor, the fourth hand gesture: in accordance with a determination that the fifth hand gesture is the first type of gesture, the computer system displays, via the display generation component, an indication that a fourth first user interface object (e.g., a next user interface object that was selected) is selected; and in accordance a determination that the fifth hand gesture is the second type of gesture, the computer system displays, via the display generation component, the indication that the first user interface object (e.g., a previous user interface object that was selected) is selected. In some embodiments, while displaying, via the display generation component, the indication that the third user interface object is selected, the computer system detects, via at least the optical sensor, a respective hand gesture. In some embodiments, in response to detecting the respective hand gesture and in accordance with a determination that the respective hand gesture is the first type of gesture, the computer system displays the indication that a fourth user interface object is selected that is different from the first, second, and third user interface objects. In some embodiments, in response to detecting the respective hand gesture and in accordance a determination that the respective hand gesture is the second type of gesture, the computer system displays the indication that the first user interface object is selected. Choosing whether to display an indication that a fourth first user interface object or to display the indication that the first user interface object is selected based on the type of hand gesture that is detected while the indication that the second user interface object is selected provides the user with more control of the system and helps the user navigate (e.g., consistently navigate the user interface in the same way) the user interface without touching the computer system, which can lead to more efficient control of the user interface for some users. 
     In some embodiments, while displaying the user interface that includes the first user interface object, the computer system detects a request to transition the computer system from a first operation mode to a fourth operation mode (e.g., as discussed above in relation to  FIGS.  13 A- 13 G  and  FIG.  14   ) (e.g., an operation mode where the computer system does not perform an operation in response to detecting a hand gesture and/or a mode where the computer system does not detect one or more hand gestures). In some embodiments, in response to detecting the request to transition the computer system from the first operation mode to the fourth operation mode, the computer system transitions the computer system from the first operation mode to the fourth operation mode (e.g., as described above in relation to  7 A- 7 C). In some embodiments, while the computer system is in the fourth operation mode and while displaying the user interface that includes the first user interface object, the second user interface object, and the third user interface object, and the indication that the first user interface object is selected, the computer system detects, via at least the optical sensor, a sixth hand gesture (e.g., as described above in relation to  7 A- 7 C). In some embodiments, in response detecting, via least the optical sensor, the sixth hand gesture (e.g., and while the computer system is in the fourth operation mode) (e.g., as described above in relation to  7 A- 7 C): in accordance with a determination that the hand gesture is the first type of gesture, the computer system continues to display the indication that the first user interface object is selected (and without displaying, via the display generation component, the indication that the second user interface object is selected and/or the indication that the third user interface object is selected and/or without performing an operation) (e.g., as described above in relation to  7 A- 7 C); and in accordance with a determination that the hand gesture is the second type of gesture, the computer system continues to display the indication that the first user interface object is selected (and without displaying, via the display generation component, the indication that the third user interface object is selected and/or the indication that the second user interface object is selected and/or without performing an operation) (e.g., as described above in relation to  7 A- 7 C). Continuing to display the indication that the first user interface object is selected in accordance with a determination that the hand gesture is the first type of gesture and in accordance with a determination that the hand gesture is the first type of gesture (e.g., and while the computer system is in the fourth operation mode) provides the user with more control of the system to control the computer system detection of hand gestures and/or performance of operations in response to detecting hand gestures. 
     Note that details of the processes described above with respect to method  1500  (e.g.,  FIG.  15   ) are also applicable in an analogous manner to the methods described herein. For example, method  1500  optionally includes one or more of the characteristics of the various methods described herein with reference to method  1600 . For example, method  1500  can be performed when the computer system is switched from operating in an operation mode in which the computer system is operating using the techniques of method  1600 . For brevity, these details are not repeated below. 
       FIG.  16    is a flow diagram illustrating a method for navigating using a computer system in accordance with some embodiments. Method  1600  is performed at a computer system (e.g.,  100 ,  300 ,  500 ) (e.g., a wearable device (e.g., a smartwatch)) that is in communication with a display generation component (e.g., a display controller, a touch-sensitive display system). In some embodiments, the computer system is in communication with one or more sensors (e.g., one or more biometric sensors (e.g., a heart rate sensor, a camera), a gyroscope, an accelerometer)). In some embodiments, the computer system is in communication with one or more input devices (e.g., a touch-sensitive surface, a microphone). In some embodiments, the computer system is in communication with one or more output devices (e.g., one or more speakers, one or more microphones). Some operations in method  1500  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  1600  provides an intuitive way for navigating user interfaces using hand gestures. The method reduces the cognitive burden on a user for navigating user interfaces using hand gestures, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to navigate user interfaces faster and more efficiently conserves power and increases the time between battery charges. 
     The computer system displays ( 1602 ), via the display generation component, a user interface (e.g.,  710 ,  720 ,  810 , or  780 ) that includes a selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and a cursor (e.g.,  742 ) (e.g., a user interface object, a non-selectable user interface object) that is displayed at a first location (e.g., a location that is different form the location of the user interface object) on the user interface. 
     While displaying the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) at the first location on the user interface (e.g.,  710 ,  720 ,  810 , or  780 ), the computer system detects ( 1604 ) a request to move the cursor (e.g.,  742 ) (e.g., via hand gesture (e.g., tilting of wrist and/or one or more other hand gestures as described above in relation to method  1500 )) from the first location to a second location (e.g., a location that is different from the first location) on the user interface. In some embodiments, the request to move the cursor is detected based on movement of the computer system, movement of one or more devices (e.g., a mouse) that is associated with the computer system, and/or one or more inputs/gestures (e.g., a swipe gesture) detected on the display generation component of the computer system. 
     In response to ( 1606 ) detecting the request (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) to move the cursor from the first location to the second location, the computer system displays ( 1608 ) the cursor at the second location (e.g., moving the cursor from the first location to the second location). In some embodiments, as a part of displaying the cursor at the second location, the computer system moves the cursor from the first location to the second location. In some embodiments, the computer system moves the cursor according to a direction in which the computer system was moved. 
     In response to ( 1606 ) detecting the request (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) to move the cursor from the first location to the second location, the computer system, in accordance with a determination that the second location corresponds to a location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) (and/or corresponds to an area (e.g., an edge) of the display), displays ( 1610 ) an animation that provides a visual indication (e.g.,  744 ) of how long the cursor (e.g.,  742 ) needs to be located at the second location to perform an operation (e.g., an animation of the visual indication (e.g., an object) filling up, changing color, flashing, counting down/up, increasing/decreasing in size, fading in/out), where the visual indication (e.g.,  742 ) is updated over a period of time (e.g., a period of time less than or equal to a threshold period of time) (e.g., while the cursor/visual indication is displayed at the second location) (e.g., without perform an action that includes selecting the selectable user interface object). In some embodiments, while displaying the animation (e.g., for less than the period of time), the computer system detects a request to move the cursor and, in response to detecting the second request, the computer system ceases to display the animation. In some embodiments, after displaying the animation, the computer system re-displays the cursor. In some embodiments, the cursor is the visual indication and/or includes the visual indication. 
     In response to ( 1606 ) detecting the request (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) to move the cursor from the first location to the second location, the computer system, in accordance with a determination that the second location does not correspond to the location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) (and/or does not correspond to an area (e.g., an edge) of the display), the computer system forgoes displaying ( 1612 ) the animation (e.g., that provides the indication (e.g.,  744 )) (and continues to display the cursor) (e.g., without perform an action that includes selecting the selectable user interface object). In some embodiments, as a part of displaying the animation that provides the visual indication, the computer system replaces display of the cursor with the visual indication. In some embodiments, while displaying the animation, the computer system detects a request to move the cursor from the second location to the third location and, in response to detecting the request to move the cursor from the third location to the second location, displays the cursor at the third location (e.g., without displaying the visual indication and/or replacing the visual indication with the cursor). In some embodiments, the third location is different from the second location and/or the first location. 
     In some embodiments, in response to detecting the request (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) to move the cursor (e.g.,  742 ) from the first location to the second location and in accordance with a determination that the second location corresponds to the location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) is displayed at the second location for more than a first threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system performs the operation (e.g., as discussed in relation to  FIGS.  7 I- 7 U , as discussed above in relation to  FIGS.  8 A- 8 J ). In some embodiments, as a part of performing the operation, the computer system selects the selectable user interface object (e.g., as discussed in relation to  FIGS.  7 I- 7 U , as discussed above in relation to  FIGS.  8 A- 8 J ) (e.g., highlighting the selectable user interface object, launching a menu corresponding to the selectable user interface object, launching an application corresponds to the selectable user interface object). Automatically performing the operation that includes selecting the selectable user interface object in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time allows the computer system to automatically select a user interface object when prescribed conditions are met. Performing the operation that includes selecting the selectable user interface object in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time provides the user with more control over the computer system by giving the user the ability to select a user interface object when the cursor has been positioned (e.g., by the user) in a certain location over a certain period of time. 
     In some embodiments, in response to detecting the request to move the cursor (e.g.,  742 ) from the first location to the second location and in accordance with a determination that the second location corresponds to the location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) is displayed at the second location for more than a second threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system performs the operation (e.g., as discussed in relation to  FIGS.  7 I- 7 U ). In some embodiments, performing the operation includes launching an application that corresponds to the selectable user interface object (e.g., as discussed in relation to  FIGS.  7 I- 7 U ). Automatically performing the operation that includes launching an application that corresponds to the selectable user interface object in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time allows the computer system to automatically launch an application that corresponds to the selectable user interface object when prescribed conditions are met. Performing the operation that includes launching an application that corresponds to the selectable user interface object in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time provides the user with more control over the computer system by giving the user the ability to launch an application that corresponds to the selectable user interface object when the cursor has been positioned (e.g., by the user) in a certain location over a certain period of time. 
     In some embodiments, in response to detecting the request to move the cursor from the first location to the second location and in accordance with a determination that the second location does not correspond to the location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ), forgoing performing the operation (e.g., as described above in relation to  FIG.  8 C ) (e.g., forgoing displaying, via the display generation component, the menu that includes the one or more user interface objects to preform one or more operations at the second location, forgoing launching an application corresponds to the selectable user interface object). In some embodiments, in accordance with a determination that the second location does not correspond to the location of the selectable user interface object and the cursor is displayed and/or not displayed for more than the threshold period of time, the computer system forgoes performing the operation. Choosing not to perform the operation in accordance with a determination that the second location does not correspond to the location of the selectable user interface object gives the computer system the ability to not perform the operation when prescribed conditions are not met and helps the computer system avoid performing unnecessary and/or unintended operations. 
     In some embodiments, in response to detecting the request to move the cursor (e.g.,  742 ) from the first location to the second location and in accordance with a determination that the cursor (e.g.,  742 ) is not displayed at the second location for more than a third threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system forgoes performing the operation (e.g., as illustrated in  FIG.  8 D ). In some embodiments, in accordance with a determination that the second location corresponds and/or does not correspond to the location of the selectable user interface object and the cursor is not displayed at the second location for more than the threshold period of time, the computer system forgoes performing the operation. Choosing not to perform the operation in accordance with a determination that the cursor is not displayed at the second location for more than a third threshold period of time gives the computer system the ability to not perform the operation when prescribed conditions are not met and helps the computer system avoid performing unnecessary and/or unintended operations. 
     In some embodiments, in response to detecting the request to move the cursor (e.g.,  742 ) from the first location to the second location and in accordance with a determination that the second location corresponds to (e.g., is) a location that is in an area (e.g.,  742  in  FIG.  7 Q or  742    in  FIG.  7 Y ) (e.g., an edge, left edge, right edge) of the display generated component and the cursor is displayed at the second location for more than a fourth threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system performs a second operation that includes displaying a second user interface (e.g.,  780  or  720 ) that is different from the user interface (e.g.,  710  or  718 ) (and ceasing to display the user interface) (while continuing to display the cursor) (without displaying the menu) (e.g., that is different from the operation (e.g., selecting the user interface object)). In some embodiments, as a part of displaying a second user interface that is different from the user interface, the computer system displays an animation (e.g., a sliding animation, fading animation, dissolving animation, and/or sliding animation) of the second user interface replacing the user interface. In some embodiments, the animation includes slider the user interface off the screen towards the area and/or sliding a second user interface object on the screen towards the area. In some embodiments, in accordance with a determination that the second location corresponds to the location that is in the area of the display and the cursor is not displayed at the second location for more than a threshold period of time, the computer system forgoes performing the second operation that includes displaying the second user interface and/or continues to display the user interface. In some embodiments, the second threshold period of time is the same period of time as the threshold period of time. In some embodiments, the second threshold period of time is a different threshold period of time than the threshold period of time. In some embodiments, the area does not include one or more selectable user interface objects. In some embodiments, in accordance with a determination that the second location corresponds to (e.g., is) the location that is in the area, the computer system displays the animation. In some embodiments, in accordance with a determination that the second location corresponds to (e.g., is) the location that is in the area, the computer system forgoes displaying the animation. In some embodiments, in accordance with a determination that the second location does not correspond to (e.g., is) the location that is in the area, the computer system displays the animation. In some embodiments, in accordance with a determination that the second location does not correspond to (e.g., is) the location that is in the area, the computer system forgoes displaying the animation. Automatically performing a second operation that includes displaying a second user interface that is different from the user interface in accordance with a determination that the second location corresponds to a location that is in an area of the display generated component and the cursor is displayed at the second location for more than a fourth threshold period of time allows the computer system to display another user interface when the cursor is in a particular area of the display generation component. Performing a second operation that includes displaying a second user interface that is different from the user interface in accordance with a determination that the second location corresponds to a location that is in an area of the display generated component and the cursor is displayed at the second location for more than a fourth threshold period of time provides the user with more control over the computer system by giving the user the ability to display another user interface when prescribed conditions are met. 
     In some embodiments, in accordance with a determination that the second location corresponds to a location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) is displayed at the second location for more than a fifth threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds) (e.g., a while displaying the cursor at the second location) (e.g., a period of time that is longer than or equal to the time that the animation is displayed) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system performs the operation. In some embodiments, performing the operation includes displaying, via the display generation component, a menu (e.g.,  732 ) that includes one or more selectable options (e.g.,  732   a - 732   d  and/or  1410 - 1418 ) (e.g., user interface objects) to preform one or more operations (e.g., one or more different operations) at the second location (e.g., an operation that is performed when a tap input (e.g., and/or a first type of input) (e.g., single tap input/multi-tap input) is detected at the second location (e.g., an operation to launch an application), an operation that is perform when a press-and-hold input (e.g., and/or a second type of input that is different from the first type of input) is detected at the second location (e.g., an operation that to bring up a menu for deleting the user interface object), an operation that is perform when a swipe input (e.g., a third type of input that is different from the first type of input and the second type of input) is detected at the second location, an operation to start an automatic scroll operation at the second location). In some embodiments, the menu is displayed concurrently with the selectable user interface object and/or the cursor. In some embodiments, when the menu is displayed, one or more portions of the user interface (e.g., that does not include the selectable user interface object and/or the cursor) cease to be displayed. In some embodiments, the menu is displayed at a location (e.g., top/bottom) on the user interface that does not include the selectable user interface object and/or the cursor. In some embodiments, in accordance with a determination that the selectable user interface object and/or the cursor is displayed at a first respective, the menu is displayed at a second respective location (e.g., that is different from the first location, that is on an opposite side of the display than the first respective location) (without being displayed at the first respective location). In some embodiments, in accordance with a determination that the selectable user interface object and/or the cursor is not displayed at the first respective location, the menu is displayed at the first respective location (without being displayed at the second respective location). Automatically performing the operation that includes displaying a menu that includes one or more selectable options to perform one or more operations at the second location in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time allows the computer system to automatically display the menu when prescribed conditions are met. Performing the operation that includes displaying a menu that includes one or more selectable options to perform one or more operations in accordance with a determination that the second location corresponds to the location of the selectable user interface object and the cursor is displayed at the second location for more than a first threshold period of time provides the user with more control over the computer system by giving the user the ability to display the menu to perform one or more operations after the cursor has been positioned (e.g., by the user) in a certain location over a certain period of time. 
     In some embodiments, the one or more selectable options (e.g.,  732   a - 732   d ) include a first selectable option (e.g.,  832   a ,  1410   a ,  1410   b ,  1410   c , or  1412 ) for performing an selection operation, and wherein selection of the first selectable option causes the computer system to perform the selection operation (e.g., an action that is performed when a tap is received at the second location) at the second location (e.g., on the selectable user interface object). In some embodiments, in response to detecting selection of the first selectable option, the computer system performs a selection operation that includes launching an application associated with the selectable user interface object. In some embodiments, in response to detecting selection of the first selectable option, the computer system performs a selection operation that includes emphasizing (e.g., highlight) the selectable user interface object that is displayed at the second location. Displaying a menu that includes a first selectable option for performing a selection operation provides the user with more control over the computer system by allowing the user to cause the computer system to perform the selection operation (e.g., without providing more complex hand gestures) and also reduces the number of hand gestures that are used to perform the operation. 
     In some embodiments, the one or more selectable options include a second selectable option (e.g.,  832   a ) for performing an operation (e.g., launching an application in response to an input (e.g., tap input, a press-and-hold input, a swipe input), moving the selectable user interface object that is displayed at the second location in response to an input (e.g., tap input, a press-and-hold input, a swipe input), displaying a notification (e.g., a pop-up) that corresponds to the selectable user interface object that is displayed at the second location) that corresponds to (e.g., that is) an operation that is (and/or that would be) performed in response to an input (e.g., tap input, a press-and-hold input, a swipe input) (and/or gesture) being detected (e.g., by the computer system) at the second location, and wherein selection of second selectable option causes the computer system to perform the operation that corresponds to the operation that is performed in response to the input being detected at the second location (e.g., without input being detected at the second location). Displaying a menu that includes a second selectable option for performing an operation that corresponds to an operation that is performed in response to an input being detected at the second location provides the user with more control over the computer system by allowing the user to cause the computer system to perform an operation at is performed in response to an input being detected at the second location (e.g., without providing more complex hand gestures and without the user touching the computer system and/or the display generation component) and also reduces the number of hand gestures that are used to perform the operation. 
     In some embodiments, the one or more selectable options include a third selectable option (e.g.,  732   a ,  1410   c , or  1412 ) for performing an automatic scroll operation (e.g., as described in relation to method  1500 ), and wherein selection of the third selectable option causes the computer system to automatically scroll through a plurality of selectable user interface objects that include the selectable user interface object. In some embodiments, as a part of automatically scrolling through a plurality of selectable user interface objects that include the selectable user interface object, the computer system starts the automatically scrolling from the second location (e.g., from the selectable user interface object that is displayed at the second location). In some embodiments, as a part of automatically scrolling through a plurality of selectable user interface objects that include the selectable user interface object, the computer system emphasizes (e.g., highlight) one or more selectable user interface objects in sequence (e.g., as described in relation to method  1500 ). Displaying a menu that includes a third selectable option for performing an automatic scroll operation provides the user with more control over the computer system by allowing the user to cause the computer system to automatically scroll through a plurality of selectable user interface objects that include the selectable user interface object (e.g., without providing more complex hand gestures) and also reduces the number of hand gestures that are used to perform the operation. 
     In some embodiments, the one or more selectable options include a fourth selectable option for displaying one or more options additional options (e.g.,  1416 ) (e.g., an option that corresponds to an option to perform an operation that corresponds to an operation that is performed when an input is detected at the location of the selectable user interface object (e.g., second location); an option to perform operation, such as turning on/off the computer system, displaying a different menu and/or user interface; and/or an option that corresponds to an operation that is perform in response to detecting an input via one or more input devices in communication with the computer system). In some embodiments, selection of the fourth selectable option causes the computer system to display the one or more additional options (e.g.,  832   a  and menu displayed in  FIG.  8 J ) that were not previously displayed before selection of the fourth selectable option was detected. In some embodiments, in response to detecting of the fourth selectable option, the computer system ceases to display one or more selectable options that were displayed before selection of the fourth selectable option was detected. Displaying a menu that includes a fourth selectable option for displaying one or more options additional options provides the user with more control over the computer system by allowing the user to choose to display additional selectable options that were not previously displayed, reduces the number of hand gestures that are used to perform additional operations, and reduces the number of selectable user interface options that were not previously displayed before selection of the fourth selectable option was detected. 
     In some embodiments, the one or more additional options (e.g.,  832   a  and menu displayed in  FIG.  8 J ) that were not previously displayed before selection of the fourth selectable option (e.g.,  1414  or  1416 ) was detected includes a respective additional option (e.g.,  1414   a - 1414   d  or  1416   a - 1416   c ) wherein selection of the respective additional option does not cause the computer system to perform an operation that is not performed at the second location (e.g., an exit operation, a close menu operation). In some embodiments, the one or more selectable options does not include a selection operation that, when selected, causes the computer system to perform an (e.g., any operation) operation that is not perform at (e.g., initiated at, performed on, and/or involves) the second location. Displaying a menu that includes the one or more additional options that were not previously displayed before selection of the fourth selectable option was detected includes a respective additional option provides the user with more control over the computer system by allowing the user to choose to select an option to perform an operation that is not performed at the second location and reduces the number of hand gestures that are used to perform the operation that is not performed at the second. 
     In some embodiments, the computer system (e.g.,  600 ) is in communication with one or more input devices (e.g.,  602   a - 602   c ). In some embodiments, the one or more selectable options include a fifth selectable option (e.g.,  732   a ,  1410   c , or  1416   b ) for performing an operation that corresponds to (e.g., that is) an operation (e.g., a press (e.g., single and/or multi-press) on hardware input device to display a menu, initiate a payment operation, initiate turning the computer system off, initiate use of a voice assistance; a rotation of hardware input device to move the cursor from one location to another location; and/or a rotation of hardware input device to zoom, scroll, and/or adjust one or more components of the user interface) that is (and/or would be) performed in response to detecting an input via the one or more input devices (e.g., a hardware button (e.g., a crown of a smartwatch, a hardware button that is rotatable, a hardware button that can be pressed/de-pressed), a hardware slider). In some embodiments, selection of the fifth selectable option causes the computer system to perform the operation that corresponds to the operation that is performed in response to detecting the input via the one or more input devices (e.g., without input at the one or more input devices being detected). Displaying a menu that includes a fifth selectable option for performing an operation that corresponds to an operation that is performed in response to detecting an input via the one or more input devices provides the user with more control over the computer system by allowing the user to choose to perform an operation that corresponds to an operation that is performed in response to an input being detected via the one or more input devices (e.g., without providing more complex hand gestures and without the user touching the one or more input devices) and also reduces the number of hand gestures that are used to perform the operation. 
     In some embodiments, the one or more selectable options include a sixth selectable option (e.g.,  732   a - 732   d  or  1410 - 1418 ) and a seventh selectable option (e.g.,  732   a - 732   d  or  1410 - 1418 ) (e.g., that is different from the sixth selectable option). In some embodiments, while displaying the menu (e.g.,  732 ), the computer system detects a request (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) to move the cursor from the second location to a third location on the user interface. In some embodiments, the second request to move the cursor is detected based on movement of the computer system, movement of one or more devices (e.g., a mouse) that is associated with the computer system, and/or one or more inputs/gestures (e.g., a swipe gesture) detected on the display generation component of the computer system. In some embodiments, in response to detecting the request to move the cursor from the second location to the third location on the user interface, the computer system: in accordance with a determination that the third location corresponds to a location of the sixth selectable option and the cursor is displayed at the third location for more than a sixth threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), performs a first operation that corresponds to the sixth selectable option (e.g., without perform the second operation); and in accordance with a determination that the third location corresponds to a location of the seventh selectable option and the cursor is displayed at the third location for more than the sixth threshold period of time, performs a second operation that is different from the first operation (e.g., without perform the first operation). In some embodiments, in accordance with a determination that the third location corresponds to the location of the sixth selectable option and the cursor is not displayed at the third location for more than the third threshold period of time, the computer system forgoes performing the first operation. In some embodiments, in accordance with a determination that the third location corresponds to the location of the seventh selectable option and the cursor is not displayed at the third location for more than the third threshold period of time, the computer system forgoes performing the first operation. In some embodiments, the third threshold period of time is the same period of time as the threshold period of time. In some embodiments, the third threshold period of time is a different threshold period of time than the threshold period of time. Performing different operations based on where the cursor is displayed for the threshold period of time provides the user with more control over the computer system to perform different operations based on the location of the cursor. 
     In some embodiments, (e.g., while displaying the cursor at the second location and the second location corresponds the selectable user interface object) the one or operations include an operation that causes the computer system (e.g.,  600 ) to display a user interface for an application that corresponds to the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) (e.g., as discussed above in relation to  FIG.  8 J ) (e.g., without exiting a first mode). 
     In some embodiments, (e.g., while displaying the cursor at the second location and the second location corresponds the selectable user interface object) the one or more operations include an operation that causes the computer system to transitioned from a first operation mode to a second operation mode (e.g., as discussed above in relation to  732   a  and/or  1412 ) (e.g., an operation mode, where an operation (e.g., auto-scrolling operation, motion pointer operation) that is initiated at (and/or starts from) the second location) (e.g., without launching an application that corresponds to the selectable user interface object). 
     In some embodiments, after displaying the menu (e.g.,  732 ) that includes the one or more selectable options (e.g., when the menu is displayed, the one or more menu objects are displayed), the computer system detects a request to display a second user interface that is different from the user interface (e.g., as illustrated above in relation to  FIGS.  7 I- 7 U and  8 A- 8 J ). In some embodiments, in response to detecting the request to display the second user interface, the computer system displays the second user interface (and while operation in the first operation mode). In some embodiments, the second user interface does not include the menu and includes a second selectable user interface object (e.g.,  732   a - 732   d  or  1410 - 1418 ) (e.g., that is different from the selectable user interface object) and the cursor (e.g.,  744  (e.g., as illustrated above in relation to  FIGS.  7 I- 7 U and  8 A- 8 J ). In some embodiments, while displaying the second selectable user interface object and the cursor, the computer system detects a request to move the cursor from a fourth location on the second user interface to a fifth location on the second user interface (e.g., as illustrated above in relation to  FIGS.  7 I- 7 U and  8 A- 8 J ). In some embodiments, the third request to move the cursor is detected based on movement of the computer system, movement of one or more devices (e.g., a mouse) that is associated with the computer system, and/or one or more inputs/gestures (e.g., a swipe gesture) detected on the display generation component of the computer system. In some embodiments, in response to detecting the request to move the cursor from the fourth location on the second user interface to a fifth location on the second user interface, the computer system displays the cursor at the fifth location on the second user interface (e.g., as illustrated above in relation to  FIGS.  7 I- 7 U and  8 A- 8 J ). In some embodiments, in response to detecting the request to move the cursor from the fourth location on the second user interface to a fifth location on the second user interface, the computer system and in accordance with a determination that the fifth location corresponds to a location of the second selectable user interface object and the cursor is displayed at the second location for more than a seventh threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system re-displays, via the display generation component, the menu (e.g.,  732 ) that includes the one or more selectable options (e.g., as illustrated above in relation to  FIGS.  7 I- 7 U and  8 A- 8 J ) (e.g., when the menu is displayed, the one or more menu objects are displayed). In some embodiments, in accordance with a determination that the fifth location does not correspond to a location of the second selectable user interface object and/or the cursor is not displayed at the second location for more than a seventh threshold period of time, forgoing displaying the menu. Automatically choosing to re-display the menu in accordance with a determination that the fifth location corresponds to a location of the second selectable user interface object and the cursor is displayed at the second location for more than a seventh threshold period of time allows the computer system to provide a consistent menu to the user when a same set of prescribed conditions are met for a different selectable user interface object. 
     In some embodiments, the request to move the cursor (e.g.,  742 ) from the first location to the second location is detected when a determination is made that the computer system (e.g.,  600 ) has been titled (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) (e.g., one side (e.g., right side, left side) of the computer system is higher/lower than another side of the computer system) in a respective direction. In some embodiments, the determination is made using data that is detected via one or more gyroscopes that are in communication with the computer system. In some embodiments, the respective direction is a direction that goes from the higher side of the computer system to the lower side of the computer. In some embodiments, the cursor (e.g.,  742 ) is moved in a direction that corresponds to the respective direction. 
     In some embodiments, before displaying the user interface that includes the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) that is displayed at the first location on the user interface, the computer system displays a third user interface. In some embodiments, while displaying the third user interface (e.g.,  710 ,  720 ,  810 , or  780 ) (and, in some embodiments, the user interface includes the selectable user interface object), the computer system detects a request (e.g.,  750   w ,  850   a ) to enter a first operation mode. In some embodiments, in response to detecting the request to enter the first operation mode, the computer system transitions the computer system (e.g.,  600 ) from a second operation mode (e.g., that is different from the first operation mode) to the first operation mode. In some embodiments, in response to detecting the request to enter the first operation mode, the computer system displays the cursor (e.g., at the first location) (e.g., and/or the user interface that includes the selectable user interface object and the cursor that is displayed at the first location on the user interface). Displaying the cursor in response to detecting the request to enter the first operation mode provides the user with visual feedback that the computer system is operating in the first operation mode (e.g., /or that one or more user actions can cause the computer system to perform one or more particular operation because the computer system is in the first operation mode). 
     In some embodiments, as a part of detecting the request to enter the first operation mode, the computer system detects that the computer system has been (or is being) shaken (e.g.,  750   w ,  850   a ) (e.g., while the computer system is in the second operation mode). Transitioning the computer system from being in a second operation mode to the first operation mode in response to detecting that the computer system has been shaken provides the user with more control over the computer system by allowing the user to switch between modes by shaking the computer system (e.g., and without providing input on the display generation component of the device). 
     In some embodiments, while the computer system is in the first mode, the computer system detects that the computer system (e.g.,  600 ) has been shaken (e.g.,  750   w ,  850   a ). In some embodiments, in response to detecting that the computer system has been shaken, the computer system transitions the computer system from the first operation mode to a third operation mode (and, in some embodiments, the third operation mode is the second operation mode) (e.g., the first operation mode as described above in relation to method  1500 ). Transitioning the computer system from the first operation mode to a third operation mode in response to detecting that the computer system has been shaken provides the user with more control over the computer system by allowing the user to switch between modes by shaking the computer system (e.g., and without providing input on the display generation component of the device). 
     In some embodiments, as a part of transitioning the computer system (e.g.,  600 ) from the first operation mode to a third operation mode, the computer system ceases to display the cursor (e.g.,  742 ). In some embodiments, in response to detecting that the computer system has been shaken (e.g., while the computer system is in the first mode), the computer system ceases to the display the cursor. Ceasing to display the cursor in response to detecting that the computer system has been shaken provides the user with feedback that the computer system is not operating in the first operation mode (e.g., and/or that one or more user actions cannot cause the computer system to perform one or more particular operation because the computer system is not in the first operation mode). 
     In some embodiments, while the computer system is in the third operation mode and while the cursor (e.g.,  742 ) is displayed, the computer system detects a request to move the cursor from the sixth location to the seventh location. In some embodiments, in response to detecting the request to move (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) the cursor from the sixth location to the seventh location (e.g., while the computer system is in the third operation mode), the computer system displays the cursor at the seventh location. In some embodiments, in response to detecting the request to move (e.g.,  750   p ,  850   c ,  850   d , or tilting in  FIG.  7 Y or  7 Z ) the cursor from the sixth location to the seventh location (e.g., while the computer system is in the third operation mode) and in accordance with a determination that the seventh location corresponds to a location of the selectable user interface object and the cursor is displayed at the seventh location for more than an eighth threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds)) (e.g., a period of time that is longer than or equal to the time that the animation is displayed), the computer system forgoes performing the operation. Forgoing performing the operation in accordance with a determination that the seventh location corresponds to a location of the selectable user interface object and the cursor is displayed at the seventh location for more than an eighth threshold period of time (e.g., while the computer system is in the third operation mode) provides the user with more control over the computer system to control when certain hand gestures will perform certain operations. 
     In some embodiments, in response to detecting the request to move the cursor (e.g.,  742 ) from the first location to the second location and in accordance with a determination that the second location corresponds to the location of the selectable user interface object (e.g.,  720   c ,  732   c ,  810   d , or  832   a ) and the cursor (e.g.,  742 ) is displayed at the second location for more than a ninth threshold period of time (e.g., a non-zero period of time) (e.g., 1-5 seconds) (e.g., a while displaying the cursor at the second location) (e.g., a period of time that is longer than the time that the animation is displayed), the computer system performs the operation. In some embodiments, as a part of performing the operation, in accordance with a determination that one or more settings (e.g., user settings) of the computer system is in a first state, the computer system displays a second menu that includes one or more selectable options (e.g., user interface objects) to preform one or more operations (e.g., one or more different operations) at the second location without launching a second application corresponding to the selectable user interface object. In some embodiments, as a part of performing the operation, in accordance with a determination that one or more settings (e.g., user settings) of the computer system is in a first state, the computer system launches the second application that corresponding to the selectable user interface object without displaying the second menu that includes one or more selectable options (e.g., user interface objects) to preform one or more operations (e.g., one or more different operations) at the second location. Choosing whether to launch a second application and/or display a second menu when prescribed conditions are met provides the user with more control over the computer system to change whether one or more actions will cause an application to be launch and/or cause a menu to be displayed. 
     Note that details of the processes described above with respect to method  1600  (e.g.,  FIG.  16   ) are also applicable in an analogous manner to the methods described herein. For example, method  1600  optionally includes one or more of the characteristics of the various methods described herein with reference to method  1500 . For example, method  1600  can be performed when the computer system is switched from operating in an operation mode in which the computer system is operating using the techniques of method  1500 . 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 improve the detection of hand gestures. 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 improve the detection of hand gestures for the user. Accordingly, use of such personal information data enables users to have calculated control of the user of data that can improve the detection of hand gestures. 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 user interface management (e.g., including navigation), 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 another example, users can select not to provide heart rate data and/or other data, which can be used to improve the detection of hand gestures. In yet another example, users can select to limit the length of heart rate data and/or other data is maintained. 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, hand gestures can be detected 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 data detection services, or publicly available information.
