     FIELD 
     The disclosed examples relate generally to user interfaces of electronic devices. 
     BACKGROUND 
     Consumers often own multiple electronic devices. Such electronic devices may be portable devices like cellular phones, tablet computers, laptops, digital audio players, and so forth. Such electronic devices may also be home electronics like audio-visual equipment, home security equipment, home automation equipment, appliances, and so forth. Such electronic devices may also be integrated with equipment not traditionally labeled as electronic devices. For example, such electronic devices may include telematics equipment that is integrated with an automobile. 
     SUMMARY 
     User interfaces for remotely controlling target electronic devices using a personal electronic device with a touch-sensitive display are disclosed. In some examples, at an electronic device with a touch-sensitive display, where the touch-sensitive display comprises one or more sensors to detect the intensity of contacts with the touch-sensitive display, a plurality of icons representing applications, including an icon representing a remote control application, are displayed. A first contact on the touch-sensitive display at a location of the icon is received. The electronic device determines whether a target device out of a plurality of target devices is responsive to remote control. In response to the first contact and a determination of the target device being responsive to remote control, the electronic device displays a first plurality of remote controls for the target device. Further, while displaying the first plurality of remote controls, the electronic device receives a second contact on the touch-sensitive display, the second contact having a maximum intensity. In response to receiving the second contact and a determination that the maximum intensity is below a threshold intensity, the electronic device instructs the target device to perform an operation; and in response to receiving the second contact and a determination that the maximum intensity is above the threshold intensity, the electronic device displays a second plurality of remote controls for the first target device. 
     In some examples, the electronic device displays a user interface object on the touch-sensitive display of the electronic device, where the displayed user interface object represents a remote control application. The electronic device receives data representing a contact on the displayed user interface object, and identifies a target electronic device that is responsive to remote control. In response to receiving the data representing the contact, the electronic device displays graphical user interface objects for controlling operations of the identified target electronic device. 
     In some examples, when none of the target electronic devices of the plurality of target electronic devices is responsive to remote control, the electronic device displays a plurality of graphical user interface objects representing the plurality of target electronic devices. Restated, in response to a determination that no target electronic device is responsive to remote control, the electronic device displays a plurality of graphical user interface objects that represent the plurality of target electronic devices. 
     In some examples, the electronic device receives first data representing a first contact at a location on the touch-sensitive display, the first contact having a maximum intensity below a predetermined threshold intensity, and the location is associated with an operation of a target electronic device. In response to the first contact (which is a relatively lighter touch), the device sends an instruction to the target electronic device instructing the target electronic device to perform an operation. The electronic device then additionally receives second data representing a second contact on the display, the second contact having a maximum intensity above the threshold intensity. In response to the second contact (which is a relatively harder touch), the electronic device displays a user interface for registering (e.g., pairing) a new target electronic device with the remote control application. 
     In some examples, an intermediate device relays instructions from the electronic device that is running the remote control application to the target electronic device that is being remotely controlled. That is, the electronic device sends data to an intermediate electronic device, where the data represents an instruction instructing the target electronic device to perform the operation, and an instruction is then communicated by the intermediate electronic device to the target electronic device. 
     In some examples, the target electronic device is responsive to remote control when the target electronic device is executing an application having an operation that can be requested using the remote control application. 
     In some examples, the electronic device obtains data representing a plurality of target devices, displays a user interface object representing a remote control application, and receives data representing a selection on the displayed user interface object. The electronic device determines whether the number of target devices exceeds a threshold, and in accordance with a determination that the number exceeds the threshold, the electronic device displays a plurality of graphical user interface objects representing categories of target devices, in response to receiving the data, and in accordance with a determination that the number does not exceed the threshold, the electronic device a plurality of graphical user interface objects representing the plurality of target devices, in response to receiving the data. 
     In some examples, the electronic device determines the location of a target device relative to the electronic device; and displays, on the touch-sensitive display, a user interface object representing the target device. The target device is nearby and the display position of the user interface object, on the touch-sensitive display, is based on the location of the target device relative to the electronic device in some examples. 
     In some examples, the electronic device displays a user interface object representing a remote control application on the touch-sensitive display of the electronic device, receives first data representing a zoom function on the displayed user interface object; and in response to receiving the first data representing the zoom function, displays an affordance including indication of nearby target devices capable of being remotely controlled. 
     In some examples, the electronic device receives data representing a first movement of a rotatable input device; and in response to receiving the data representing the first movement, displays only a subset of the plurality of graphical user interface objects, where the displayed subset of graphical user interface objects includes the icon representing the remote control application, and displays an affordance including indication of nearby target devices capable of being remotely controlled. 
     In some examples, the electronic device identifies a target device that is responsive to remote control out of a plurality of target devices, detects a raise gesture based on detected motion of the electronic device; and, in response to detecting the raise gesture, instructs the target device to perform an operation.

     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. 
     As discussed above, consumers often own multiple electronic devices. It is desirable for a user to be able to remotely control these electronic devices. It is also desirable for the device (i.e., the “remote control”) that is used to remotely control these electronic devices to be portable and readily accessible. It is also desirable for the remote control to support remote control of various electronic devices while maintaining a physical form factor that promotes usability. 
     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 remote control of an electronic device.  FIGS.  6 - 14  and  21 A- 22 B  illustrate exemplary user interfaces for performing examples of remote control described herein. The user interfaces in the figures are also used to illustrate the processes described below, including the processes in  FIGS.  15 A- 18 B and  24   . 
     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 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. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes one or more computer-readable storage mediums. The computer-readable storage mediums are optionally tangible and non-transitory. The computer-readable storage mediums are optionally transitory. Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips.

     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 .

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. 11/228,700, “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 (not shown) 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.

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 contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 .

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.

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 .

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 .

No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG.  1 A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) 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    are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that is, 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 is, 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  are optionally 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 which 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, 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, 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, touch-intensity sensitive component  524 . 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  may be 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 be a non-transitory computer-readable storage medium, 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 above, including processes  1500 - 1850  ( FIGS.  15 A- 18 B ) and process  2400  ( FIG.  24   ). The computer-executable instructions can also be stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory 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. 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 ,  3 , and  5   ). 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., 0.5, 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. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface is, optionally, be characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
       FIG.  6    illustrates exemplary personal electronic device  600  (hereafter device  600 ) that can have a remote control software application that permits electronic device  600  to remotely control other electronic devices. Device  600  includes body  602 . In some examples, device  600  has touch-sensitive display screen (hereafter touchscreen)  604 . Touchscreen  604  can include a display device, such as a liquid crystal display (LCD), light-emitting diode (LED) display, organic light-emitting diode (OLED) display, or the like, positioned partially or fully behind or in front of a touch sensor panel implemented using any desired touch sensing technology, such as mutual-capacitance touch sensing, self-capacitance touch sensing, resistive touch sensing, projection scan touch sensing, or the like. 
     Touchscreen  604  can allow a user to perform various functions by touching or hovering near the touch sensor panel. The user may make contact with touchscreen  604  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some examples, device  600  is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based inputs due to the larger area of contact of a finger on the touchscreen. In some examples, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     Touchscreen  604  can display graphical user interface objects. Examples of such graphical user interface objects include images, video, text, and other graphics. As used here, the term “icon” refers to a graphical user interface object—such as an image—that provides a visual indication of a device feature and optionally, when activated, initiates that feature. Also, as used here, the term “affordance” refers to a graphical user interface object—such as an image—and/or its content—such as text within the image. 
     In some examples, touchscreen  604  has one or more intensity sensors (not shown) for detecting intensity of contacts being applied. The one or more intensity sensors of touchscreen  604  can provide output data that represents the intensity of contacts. The user interface of device  600  can respond to contacts based on their intensity, meaning that contacts of different intensities can invoke different user interface operations on device  600 . As used here, the term “intensity” of a contact on touchscreen  604  refers to the force or pressure (force per unit area) of a contact (e.g., a finger) on the touchscreen. 
     In some examples, touchscreen  604  does not have the above-described intensity sensors; rather, device  600  uses a substitute (proxy) for the force or pressure of a contact on touchscreen  604 . In these examples, the size of the contact area detected on the touchscreen  604  and/or changes thereto, the capacitance of the touchscreen  604  proximate to the contact and/or changes thereto, and/or the resistance of the touchscreen  604  proximate to the contact and/or changes thereto can be used as a substitute for the force or pressure of the contact on touchscreen  604 . These substitute measurements for contact force or pressure may be 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). Alternatively, these substitute measurements for contact force or pressure may be converted to an estimated force or pressure and the estimated force or pressure may then be used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). 
     In some examples, regardless of whether touchscreen  604  has the above-described intensity sensors, device  600  can optionally communicate with a stylus having a pressure-sensitive tip that detects and provides data regarding the intensity of the stylus&#39;s contact on device  600 , particularly touchscreen  604 . 
     In some examples, device  600  has one or more input mechanisms  606  and  608 . Input mechanisms  606  and  608 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some examples, device  600  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  600  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. 
     1. Remote Control User Interface 
       FIG.  7    shows exemplary user interface screen  700  that device  600  can display on touchscreen  604 . Screen  700  can be, for example, a home screen that appears when the display of device  600  is powered on, or that appears in response to user input on device  600 . Screen  700  has icons  702 ,  704 ,  706 ,  708 , and  710 . These icons correspond to software applications that are available on device  600 . A user can make contact with icons  702 ,  704 ,  706 ,  708 , or  710  to launch a corresponding application. Launching an application means causing the application to run in the foreground of device  600  and to appear on touchscreen  604 . 
     Icon  706  corresponds to a remote control application. A remote control application allows a user to remotely control other electronic devices. These other electronic devices can be referred to as target electronic devices. Target electronic devices are capable of being remotely controlled, meaning that they have the requisite hardware and/or software to receive and act on instructions from remote controllers. Some target electronic devices, however, may not always be responsive to remote control even if they are capable. For example, a target electronic device may be configured to receive and process incoming instructions when it is running some software applications but not others. Such a target electronic device may be identified as responsive to remote control when it is executing logic (e.g., a target software application) that has an operation that can be initiated remotely (e.g., from device  600 ). In some cases, a target electronic device is responsive to remote control when it is executing a relevant target software application in the foreground, but not be responsive to remote control when the target software application is executing in the background. Device  600  may require an external electronic device to be registered with device  600  before it is treated as a target electronic device capable of remote communication. The registration process may be akin to “pairing” processes used in the context of Bluetooth™ communication, WiFi Protected Setup (WPS), operating system device setup, and the like. 
     In some examples, electronic device  600  may determine responsiveness by listening for network discovery information broadcasted by target electronic devices that are responsive to remote control. In these examples, electronic device  600  expects target electronic devices that are responsive to remote control to send out communication datagrams (e.g., using a service discovery protocol) indicating their presence and responsiveness onto a communication channel (e.g., a network). In some examples, electronic device  600  may determine responsiveness by sending requests onto a communication channel and listening for acknowledgements from target electronic devices that are responsive to remote control. In these examples, electronic device  600  expects target electronic devices that are responsive to remote control to acknowledge requests. Electronic device  600  may broadcast requests and/or target requests to registered electronic devices. In some examples, electronic device  600  may determine responsiveness using a combination of the above-described techniques. For example, electronic device  600  may actively poll for target electronic devices by sending broadcast signals when its battery level is relatively full (e.g., above a threshold), but passively listen for network discovery data from target electronic devices when its battery level is relatively empty (e.g., below a threshold). 
     A user may make contact with icon  706  to launch the remote control application. This causes device  600  to display one of several possible graphical user interface screens (e.g. landing screen). In some examples, when a user activates icon  706 , device  600  identifies whether there is a registered target electronic device that is currently responsive to remote control. If so, device  600  displays a screen depicting possible operations of the identified target electronic device. One example of a target electronic device that is responsive to remote control is a media player that is currently playing media.  FIG.  8    shows an exemplary screen for controlling such a media player. Screen  800  has graphical user interface objects  802 ,  804 , and  806  representing operations on a target electronic device that has been identified as being responsive to remote control. User interface object  802  represents a “pause” operation, object  804  represents a “fast forward” operation, and object  806  represents a “rewind” operation. These operations constitute transport operations. When a user contacts object  802 , for example, device  600  sends data representing an instruction to the media player instructing it to pause. Screen  800  may additionally include other objects representing additional transport operations (e.g., “play,” “stop,” “next,” “previous,” and so forth). In some examples, user interface object  802  (representing pause) may be replaced with a user interface object representing play after being invoked. 
     Another example of a target electronic device that is responsive to remote control is a computer that is running a presentation program, such as Microsoft™ PowerPoint or Apple™ KeyNote. In some examples, the remote control application prioritizes the display of remote controls for presentation programs. Restated, if two target devices are responsive to remote control, and one of the two target devices is running a presentation program, the remote control application may land on remote controls for the presentation program upon launch. 
     Device  600  can display other landing screens. When a user activates icon  706  ( FIG.  7   ), device  600  may be unable to identify any registered target electronic device that is currently responsive to remote control. In some examples, when this occurs, device  600  may display a screen that corresponds to the last target electronic device that was remotely controlled using device  600 , even if that target electronic device is not currently responsive. In other examples, when this occurs, device  600  may display a screen that corresponds to the last media playback device that was remotely controlled using device  600 , even if that target media device is not currently responsive. 
     In yet other examples, when this occurs, device  600  may display a graphical user interface screen permitting a user&#39;s selection of a target electronic device (from a list of devices) to control remotely.  FIG.  9    shows an example of such a screen. Screen  900  has graphical user interface objects  402 ,  404 , and  406 . These graphical user interface objects correspond to electronic devices that are capable of being remotely controlled and have been registered with device  600 . Object  902  is related to a set-top media playback device, object  904  is related to an audio player, and object  906  is related to an automobile. A user can activate one of these objects to view the remotely controllable operations of the corresponding target electronic device. For example, a user can make contact with object  904  to view transport operations for the corresponding audio player. When a user contacts object  904 , device  600  may display screen  800  ( FIG.  8   ), in some examples. 
     Device  600  can display still other landing screens. In some examples, when a user activates icon  706  ( FIG.  7   ) and device  600  determines that no registered target electronic device is currently responsive to remote control, then device  600  may display a screen for registering target electronic devices (instead of screen  900  as shown in  FIG.  9   ). The possibility of this alternate behavior means that device  600  can respond differently when it is (i) unable to detect a responsive electronic device, as opposed to when it (ii) detects affirmatively that nearby registered electronic devices exist but are not responding to remote control instructions. More specifically, device can display screen  900  ( FIG.  9   ) when (i) occurs but display a device registration screen when (ii) occurs. This distinction is especially relevant if target electronic devices can execute multiple software applications. Such target electronic devices may be responsive to remote control when certain applications are running, but be unresponsive to remote control at other times. Device  600  can thus react accordingly, meaning that in some examples device  600  avoids asking a user to register additional target electronic devices simply because his registered target electronic devices are momentarily unresponsive to remote control. 
     Returning to  FIG.  9   , a user may make contact with graphical user interface object  902  to see operations of the corresponding media player that can be controlled remotely.  FIG.  10    depicts graphical user interface screen  1000  showing the remote-controllable operations of the media player. The relevant media player may be a set-top media device or other device. Screen  1000  includes graphical user interface objects  1002 ,  1004 , and  1006  representing transport operations. A user may contact object  504 , for example, to fast-forward into the media playback. Screen  1000  also includes text (e.g., affordances) identifying the media being played. 
     As can be seen from the exemplary user interfaces screens of  800  ( FIG.  8   ) and  1000  ( FIG.  10   ), device  600  can share graphical user interface objects between different screens of its remote control application. In some examples, the sharing of graphical user interface objects refers to the re-use of graphical user interface objects to cause the same effect among different user interface screens of target electronic devices. That is, graphical user interface objects  802  ( FIG.  8   ) and  1002  ( FIG.  10   ) are shared in that they have the same visual appearance and the same effect of pausing playback on different electronic devices. In some examples, the sharing of remote control components refers to the ability of one graphical user interface object to concurrently cause the same effect across multiple target electronic devices. That is, graphical user interface object  1002  can have the effect of pausing playback on multiple set-top devices that are registered with device  600  in response to a single user contact, such as multiple living room cable boxes. 
     Device  600  can display yet still other landing screens. In some examples, when a user activates icon  706  ( FIG.  7   ), device  600  may determine the positioning of nearby target electronic devices. Device  600  may then display graphical representations of nearby target electronic devices based on their relative positions and/or proximities. For example, device  600  may determine that a first target electronic device is in front of the user and a second target electronic device is to the left of the user. In this situation, device  600  may display a first icon representing the first target electronic device near the top of touchscreen  604  and a second icon representing the second target electronic device near the left of touchscreen  604 .  FIG.  11    illustrates exemplary graphical user interface screen  1100  in which graphical user interface objects representing different target electronic devices are positioned and sized on-screen according to their positions and proximities with respect to device  600 . 
     As background, car  1110 , cellular phone  1112 , and door entry system  1114  are nearby and are positioned to the north, east, and west of device  600 , respectively. Car  1110  is physically closest to device  600  while cellular phone  1112  is farthest away. In view of these positions and proximities, device  600  displays screen  1100  having graphical user interface object  1106  (representing car  1110 ) near the top edge of touchscreen  1104 , object  1102  (representing cellular phone  1112 ) near the right edge, and object  1104  (representing door entry system  1114 ) near the left edge. In other words, in some examples, the on-screen position of a graphical user interface object corresponds to the relative position of its corresponding target electronic device with respect to device  600 . Device  600  also displays object  1106  in larger size as compared with icon  1102 . In some examples, the on-screen size of a graphical user interface object is inversely proportional to the distance between device  600  and its corresponding target electronic device. 
     Note, while distance can be measured using physical units, in some examples, distance between devices may be approximated based on meta-data such as network access delays and GPS location information, for example. 
     Device  600  can display yet still other landing screens. In some examples, when a user activates icon  706  ( FIG.  7   ), device  600  groups target electronic devices into categories and display a listing of device categories. This grouping is useful when the number of registered target electronic devices exceeds that which can be usefully displayed on touchscreen  604 . In some examples, this limit is based on a predetermined numeric threshold. In some examples, particularly where touch input is used, graphical user interface objects that are smaller than the tip of the average human index finger are considered not useful for touch input.  FIG.  12    shows exemplary graphical user interface screen  1200 . Screen  1200  has graphical user interface objects  1202 ,  1204 , and  1206  indicating the categories of “home,” “personal portable devices,” and “automotive,” respectively. A user may make contact with object  1202  to view a more detailed listing of target electronic devices related to home automation, such as media playback devices, door entry devices, lighting devices, and so forth. A user may contact object  1204  to view a more detailed listing of target electronic devices such as portable music players and cellular phones, for example. A user may contact object  1206  to view a more detailed listing of target electronic devices related to in-car telematics systems. 
     Turning to  FIG.  13   , in response to activation of graphical user interface object  1202  ( FIG.  12   ), device  600  displays graphical user interface screen  1300 . Screen  1300  includes user interface objects  1302 ,  1304 , and  1306  corresponding to target electronic devices in the Home category: User interface object  1302  corresponds to a television remote control, user interface object  1304  corresponds to a garage door opener, and user interface object  1306  corresponds to a remote lighting controller. A user may activate user interface object  1302 ,  1304 , or  1306  to launch remote control screens for these target electronic devices. 
     In some examples, device  600  may be able to detect motion that represents a raise gesture. For example, if device  600  is a wearable device configured to be worn on a user&#39;s arm, the device may be able to detect when the user has raised his arm. When a raise gesture is detected, device  600  may send an instruction that instructs a target electronic device to perform an operation, or to stop the performance of an operation. For example, device  600  may instruct a media playback device to stop (or pause) playback when a user raises the device. Techniques for determining raising gestures such as wrist raises are described in, e.g., U.S. Provisional Patent Application Ser. No. 62/026,532, “Raise Gesture Detection in a Device,” filed Jul. 18, 2014, the content of which is hereby incorporated by reference. In addition, device  600  may display user interface object representing additional controls (e.g., transport controls) for the target electronic device. 
     Device  600  can display user interface screen based on the intensity of contacts being applied to touchscreen  604  ( FIG.  6   ). Specifically, device  600  can respond differently when a user contacts touchscreen  604  of device  600  with a greater intensity than what is normally needed to activate a graphical user interface object. This aspect is described with reference to  FIGS.  22 A-B . As shown in  FIG.  22 A , device  600  may display user interface screen  2200 . Screen  2200  may be screen  800  ( FIG.  8   ) for remotely controlling a target electronic device, in this instance an audio player. A user may activate (e.g., tap) a displayed icon to invoke a corresponding transport control of the target audio player. In some examples, if the intensity of the user&#39;s contact (e.g., tap  2208 ) on icon  2204  (or more generally touchscreen  604 ) exceeds a threshold intensity, device  600  may, instead of invoking a corresponding remote operation of the target electronic device, replace the display of screen  2200  with a graphical user interface screen  2210  showing alternate features of the target electronic device. For example, as shown in  FIG.  22 B , screen  2210  include shuffling playback icon  2212 , repeating playback icon  2214 , and/or playlist and/or station icon  2216 . These features constitute alternate features. More generally, the term “alternate features” refers to features different from those features otherwise displayed on device  600  had the intensity of contact  2208  been below the threshold intensity (e.g., features corresponding to screen  2200 ). 
     2. Registering Electronic Devices 
     As discussed above, device  600  may require registration of an electronic device before allowing remote control of the electronic device. When this is the case, device  600  provides graphical user interface screens for registering target electronic devices. In some examples, device  600  proactively displays the necessary registration screens under some usage conditions, as discussed above. 
     In some examples, device  600  reactively displays the necessary registration screens when a user contacts touchscreen  604  of device  600  with a greater intensity than what is normally needed to activate a graphical user interface object. When the intensity sensors of device  600  detect a contact that has a maximum intensity that is greater than a threshold intensity, device  600  can display graphical user interface screens for registering electronic devices as target electronic devices. This aspect is described with reference to  FIGS.  21 A-B . In  FIG.  21 A , device  600  is displaying user interface screen  2100  which may be screen  900  ( FIG.  9   ) for selecting a target electronic device to remote control. A user may activate (e.g., tap) on a displayed graphical user interface object to select a corresponding electronic device that is to be remotely controlled. In some examples, if the intensity of the user&#39;s contact (e.g., tap  2108 ) on icon  2106  (or more generally touchscreen  604 ) exceeds a threshold intensity, device  600  may, instead of displaying remote controls for the corresponding electronic device, replace the display of screen  2100  with graphical user interface screen  2110 . Screen  2110 , as shown, provides an alternate feature of registering new target electronic devices. 
     Device  600  may limit what electronic devices can be registered as target electronic devices. In some examples, device  600  registers only nearby electronic devices. Device  600  may consider an electronic device to be “nearby” if the two are within the communication range of a short-range wireless communication protocol such as Bluetooth™ (whether classic or low energy), near-field communication, ZigBee™, and the like. Also, device  600  may consider an electronic device to be “nearby” if the two are within communication range of a local area network such as IEEE 802.11 network. Also, device  600  considers an electronic device to be “nearby” if the two are within communication range of a wide area network such as a cellular network, a cellular data network, or a wide area network (e.g., internet). Also, device  600  may consider network response times between itself and a target electronic device in determining whether the target electronic device is nearby. Also, device  600  may consider additional meta-data, such as GPS location information, in determining whether a target electronic device is nearby. 
     In some examples, in response to a user contact at a maximum intensity that is greater than the predetermined threshold intensity, device  600  displays a user interface for viewing and changing configuration settings associated with the remote control application. 
     3. Progressive Disclosure 
       FIG.  14 A  shows graphical user interface screen  1400 , which can be an alternative to screen  700  ( FIG.  7   ) in some examples. As shown, screen  1400  includes graphical user interface object  1402  corresponding to a remote control application. Screen  1400  also includes affordance  1406  indicating additional information related to the remote control application. Affordance  1406  may appear inside graphical user interface object  1402  (as shown), or may appear outside but adjacent to graphical user interface object  1402  (not shown). Exemplary affordances can show, for example, (i) whether at least one registered electronic device is responsive to remote control; (ii) the types and/or number of registered electronic devices responsive to remote control; (iii) the types and/or number of electronic devices capable of remote control; (iv) the types and/or number of electronic devices capable of remote control and available for registration with device  600 ; and/or (iv) the types and/or number of electronic devices registered with device  600 . These affordances can range from a simple visual indicator (such as an image) to rows of text (such as scrolling/marquee text). 
     Affordance  1402  need not always be displayed. As demonstrated by  FIG.  14 B , in some examples, affordance  1402  disappears when graphical user interface object  1406  is reduced in size. Object  1406  may become reduced in size when a user zooms-out from screen  1400  using one or more of the input mechanisms of device  600 , for example. Suitable input mechanisms may include one or more of the touchscreen(s), button(s) and rotatable mechanism described above. Restated, affordance  1402  may be displayed in one graphical user interface screen at one zoom level (e.g., screen  1400 ) but not on another screen at another zoom level (e.g., screen  1410 ). 
     4. Processes for Remotely Controlling a Target Electronic Device 
       FIG.  15 A  depicts exemplary process  1500  that device  600  can perform to control a target electronic device. At block  1510 , a graphical user interface object is displayed on a touchscreen. The graphical user interface object represents a remote control application for remotely controlling a target electronic device. At block  1520 , data representing a contact input such as a finger tap is obtained. A determination is made that the contact occurred on the user interface object representing the remote control application. In response to the determination that the received data represents a relevant contact, at block  1530 , an electronic device that can be remotely controlled is identified. The identified target electronic device may have been registered on device  600 . If the identified target electronic device is determined to be presently responsive to remote control, processing proceeds to block  1540 , where graphical user interface objects for controlling the identified target electronic device are displayed. The displayed graphical user interface objects may depend on the operations supported by the identified target electronic device. If no target electronic device is identified, processing proceeds to block  1550 , where graphical user interface objects for manually selecting a target electronic device for remote control are displayed. 
       FIG.  15 B  depicts exemplary process  1560  that device  600  can perform to control a target electronic device. At block  1565 , a graphical user interface object is displayed on a touchscreen. The graphical user interface object includes a plurality of icons including an icon that represents a remote control application for remotely controlling a target electronic device. At block  1570 , a first contact on a touch-sensitive display is received at the location of the icon. At block  1575 , a determination is made as to whether a target device out of a plurality of target devices is responsive to remote control. In response to the first contact and a determination that the target device is responsive to remote control, at block  1580 , a first plurality of remote controls for the target device is displayed. At block  1585 , while displaying the first plurality of remote controls, a second contact on the touch-sensitive display is received. The second contact has a maximum intensity in some examples. At block  1590 , in response to the second contact and a determination that the maximum intensity is below a threshold intensity, the target device is instructions to perform an operation. At block  1595 , in response to the second contact and a determination that the maximum intensity is above the threshold intensity, a second plurality of remote controls for the first target device is displayed. 
     The identified target electronic device may have been registered on device  600 . If the identified target electronic device is determined to be presently responsive to remote control, processing proceeds to block  1540 , where graphical user interface objects for controlling the identified target electronic device are displayed. The displayed graphical user interface objects may depend on the operations supported by the identified target electronic device. If no target electronic device is identified, processing proceeds to block  1550 , where graphical user interface objects for manually selecting a target electronic device for remote control are displayed. 
       FIG.  16    depicts exemplary process  1600  that device  600  can perform to control a target electronic device. At block  1610 , information representing multiple target electronic devices is obtained. The obtained information may be used to identify target electronic devices that are responsive to remote control. At block  1620 , a user interface object is displayed on touchscreen  604 . The user interface object may represent a remote control application for remotely controlling a target electronic device. At block  1630 , data representing a contact, such as a finger tap, on the user interface object is received. At block  1640 , a determination is made as to whether the number of target electronic devices that may be remotely controlled exceeds a threshold. This determination may be based on the information obtained at block  1610 . If the number of devices is determined to exceed the threshold, then processing proceeds to block  1650  where graphical user interface objects representing categories of target electronic devices are displayed. If the number of devices is determined not to exceed the threshold, then processing proceeds to block  1660  where graphical user interface objects representing target electronic devices are displayed. 
       FIG.  17    depicts exemplary process  1700  that device  600  can perform to identify target electronic devices for remote control. At block  1710 , the location of a target electronic device is determined. The location of the target electronic device relative to device  600  may be determined by obtaining network and/or location information from the target electronic devices, for example. At block  1720 , a user interface object representing the target electronic device is displayed on touchscreen  604 . The user interface object may be displayed at a location on touchscreen  604  that illustrates the location of the target electronic device relative to device  600 , as discussed above with respect to  FIG.  6   . 
       FIG.  18 A  depicts exemplary process  1800  that device  600  can perform to indicate whether target electronic device are available for remote control. At block  1810 , a relative larger number (as compared with block  1830 ) of graphical user interface objects are displayed on touchscreen  604 . The displayed graphical user interface objects include an object representing a remote control application. At block  1820 , data representing a user input is obtained form an input device of device  600 . A determination is made that the received data represents a zoom-in operation. In response to the determination that the received data represents a zoom-in operation, at block  1830 , a reduced number (as compared with block  1810 ) of graphical user interface objects are displayed on touchscreen  604 . The displayed graphical user interface objects still include the object representing the remote control application being displayed in a relatively larger size (as compared with block  1810 ). Additionally, the object representing the remote control application includes an additional affordance. The additional affordance may indicate, for example: (i) whether at least one registered electronic device is responsive to remote control; (ii) the types and/or number of registered electronic devices responsive to remote control; (iii) the types and/or number of electronic devices capable of remote control; (iv) the types and/or number of electronic devices capable of remote control and available for registration with device  600 ; and/or (iv) the types and/or number of electronic devices registered with device  600 . 
       FIG.  18 B  depicts exemplary process  1850  that device  600  can perform to indicate whether target electronic device are available for remote control. At block  1860 , a relative larger number (for example, as compared with block  1880 ) of graphical user interface objects are displayed on touchscreen  604 . The displayed graphical user interface objects include an object (e.g., icon) representing a remote control application. At block  1870 , data representing a first movement of a rotatable input device is received. In response to the receiving the data representing the first movement, at block  1880 , a reduced number (as compared with block  1860 ) of graphical user interface objects are displayed on touchscreen  604 . The displayed graphical user interface objects still include the object representing the remote control application being displayed in a relatively larger size (as compared with block  1860 ). At block  1890 , an additional affordance is displayed. The additional affordance may indicate, for example: (i) whether at least one nearby electronic device is responsive to remote control; (ii) the types and/or number of nearby electronic devices responsive to remote control; (iii) the types and/or number of electronic devices capable of remote control; (iv) the types and/or number of electronic devices capable of remote control and available for registration with device  600 ; and/or (iv) the types and/or number of electronic devices registered with device  600 . 
       FIG.  24    depicts exemplary process  2400  that device  600  can perform to control a target device. At block  2410 , a plurality of icons representing applications, including an icon representing a remote control application, are displayed. At block  2420 , data representing user input is obtained from an input device of device  600 . A determination is made that the received data represents a touch at a position of the icon representing the remote control application. At block  2430 , a target device that is responsive to remote control is identified from a larger plurality of target devices. At block  2440 , a raise gesture is detected based on motion of the electronic device detected by a motion sensor. At block  2450 , in response to detecting the raise gesture, an instruction is sent to the target device instructing the target device to perform an operation. 
     In some examples, the instruction is an instruction to stop (or pause) an operation on the target device. For example, device  600  may instruct a media player to stop (or pause) playback in response to a raise gesture. In some examples, blocks  2430 - 2450  are performed only if blocks  2410 - 2420  are performed, meaning that an electronic device would send remote control instructions only the user has launched the remote control application by touching a corresponding icon. In some examples, blocks  2430 - 2450  are performed even if blocks  2410 - 2420  are not performed, meaning that an electronic device may send remote control instructions based on raise gestures even if the user has not launched the remote control application. Techniques for detecting a raise gesture involving an electronic device may include those described in U.S. Provisional Patent Application Ser. No. 62/026,532, “Raise Gesture Detection in a Device,” filed Jul. 18, 2014, the content of which is hereby incorporated by reference. 
     5. Computing Systems 
       FIG.  19    depicts exemplary computing system  1900  that, in some examples, supports device  600 . Computing system  1900  has bus  1902  that operatively couples I/O section  1904  with one or more computer processors  1906  and memory  1908 . I/O section  1904  can be connected to display  1910 , which can have touch-sensitive component  1912  and, optionally, touch-intensity sensitive component  1930 . In addition, I/O section  1904  can be connected with communication unit  1918  for receiving application and operating system data, using Wi-Fi, Bluetooth™, near field communication (“NFC”), cellular and/or other wireless communication techniques. Computing system  1900  can include input mechanisms  1914  and/or  1916 . Input mechanism  1914  may be a rotatable input device, for example. Input mechanism  1916  may be a button, for example. Computing system  1900  can include various sensors, such as GPS sensor  1920 , accelerometer  1922 , directional sensor  1924  (e.g., compass), gyroscope  1926 , motion sensor  1928 , and/or a combination thereof, all of which can be operatively connected to I/O section  1904 . 
     Memory  1908  of computing system  1900  can be a non-transitory computer readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors  1906 , for example, can cause the computer processors to perform the remote control techniques described above, including processes  1500 - 1850  ( FIGS.  15 A- 18 B ) and process  2400  ( FIG.  24   ). The computer-executable instructions can also be stored and/or transported within any non-transitory computer readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory 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. 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. Computing system  1900  is not limited to the components and configuration of  FIG.  19   , but can include other or additional components in multiple configurations. 
       FIG.  23    shows exemplary functional blocks of an electronic device  2300  that, in some examples, perform the features described above. As shown in  FIG.  23   , an electronic device  2300  includes a display unit  2302  configured to display graphical objects; a touch-sensitive surface unit  2304  configured to receive user gestures; one or more sensor units  2306  configured to detect intensity of contacts with the touch-sensitive surface unit; and a processing unit  2308  coupled to the display unit  23002 , the touch-sensitive surface unit  2304 , and the sensor units  2306 . In some examples, the processing unit includes a detecting unit  2310 , a remote control unit  2312 , and a communication unit  2314 . The functional blocks of the device  2300  are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described examples. It is understood by persons of skill in the art that the functional blocks described in  FIG.  23    are, optionally, combined or separated into sub-blocks to implement the principles of the various described examples. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. In some examples, processing unit  2308  is configured to detect a contact (e.g., with the detecting unit  2310 ), on the touch-sensitive surface unit  2304  over a graphical user interface object; and in response to detecting the contact, instruct a target electronic device to perform an operation. The instruction may be transmitted using communication unit  2314 . 
     In some examples, processing unit  2308  is configured to detect a contact (e.g., with the detecting unit  2310 ), on the touch-sensitive surface unit  2304  over a graphical user interface object; and in response to detecting the contact: in accordance with a determination that the contact is below a predefined intensity criteria, perform a first operation (e.g., display a default set of remote control operations) using remote control unit  2312 ; and in accordance with a determination that the contact is above the predefined intensity criteria, perform a different second operation (e.g., display an alternate set of remote control operations). 
     In some examples, processing unit  2308  is configured to detect a contact (e.g., with the detecting unit  2310 ), on the touch-sensitive surface unit  2304  over a graphical user interface object. In addition, communication unit  2314  is configured to detect nearby target electronic devices. In response to detecting the contact and based on information about nearby target electronic device, device  2300  can display on display unit  2302  a plurality of graphical user interface objects representing the nearby target electronic devices. The on-screen location of the graphical user interface units can reflect the relative location of the nearby target electronic devices with respect to device  2300 . 
     6. Remote Control Via Intermediate Device 
     The availability of components in system  1900 , particularly short and long range communication interfaces, may affect the operation of device  600 . In some examples, a target electronic device may use a communication protocol not supported by device  600 . For example, the target electronic device may support WiFi but not Bluetooth™, while device  600  may support Bluetooth™ but not WiFi. In this situation, device  600  may use an intermediate device that supports both Bluetooth™ and WiFi protocols to communicate with the target electronic device. The intermediate device may be a Bluetooth™ and WiFi-enabled cellular phone, for example. 
       FIG.  20    depicts an exemplary communication path between device  600 , intermediate device  2002 , and target electronic device  2004 . Device  600  communicates with intermediate device  2002  using a first communication protocol that may not be supported by target electronic device  2004 , and intermediate device  2002  relays that communication to target electronic device  2004  using a second communication protocol that is supported by target electronic device  2004 . The reverse communication path may also be supported, meaning that target electronic device  2004  can communicate with device  600  via intermediate device  2002 . 
     Communications sent to target electronic device  2004  may include instructions that cause the target electronic device to perform an operation. In some examples, intermediate device  2002  relays an instruction from device  600  to target electronic  2004  verbatim. In some examples, intermediate device  2002  processes an instruction from device  600  and creates a corresponding instruction for transmission to target electronic device  2004 . In some examples, intermediate device  2002  modifies an instruction from device  600  and transmits the modified instruction to target electronic device  2004 . Note, in some examples, the communication path depicted by  FIG.  20    can be utilized even if device  600  and target electronic device  2004  support a common communication protocol. In these examples, the communication path depicted in  FIG.  20    may be preferred by device  600  because intermediate device  2002  contains data relevant to the remote control operation. Also, in these examples, the datagrams sent by device  600  to intermediate device  2002  need not be identical to the datagrams sent by intermediate device  2002  to target electronic device  2004 , meaning that, in “relaying” an instruction, intermediate device  2002  may create a new instruction datagram for transmission to target electronic device  2004  based on an instruction datagram received from device  600 .

A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS.  1 A- 1 B .
