Title: Devices, methods, and graphical user interfaces for wireless pairing with peripheral devices and displaying status information concerning the peripheral devices

Abstract:
In accordance with some embodiments, a method is performed at an electronic device with a display, radio frequency (RF) circuitry, and one or more input devices. The device displays a first user interface on the display. While displaying the first user interface, the device detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the device determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the device displays a pairing affordance that initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays information concerning coupling of the first peripheral and the second peripheral.

Description:
RELATED APPLICATIONS 
     This application is a continuation of U.S. application Ser. No. 15/271,114, filed Sep. 20, 2016, which claims priority to U.S. Provisional Application Ser. No. 62/383,976, filed Sep. 6, 2016, both of which are incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     This relates generally to wireless pairing of electronic devices, including but not limited to pairing an electronic device with peripheral devices and displaying status information concerning the peripheral devices. 
     BACKGROUND 
     The use of wireless peripheral devices that communicate with an electronic device of a user (e.g., a smartphone, tablet, or other computing device) has increased substantially in recent years. Wireless pairing technologies, such as Bluetooth®, are often used to connect (“pair”) peripherals to such devices. 
     But conventional methods for performing pairing are cumbersome and inefficient, especially when multiple peripheral devices are involved. For example, a user may need to pair each peripheral individually with a given electronic device, before using the peripherals with the device. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for pairing with peripheral devices and displaying status information concerning the peripheral devices. Such methods and interfaces optionally complement or replace conventional methods for pairing peripherals. Such methods and interfaces reduce the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. 
     The above deficiencies and other problems associated with user interfaces for electronic devices are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device is a personal electronic device (e.g., a wearable electronic device, such as a watch). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch-screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through stylus and/or finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, note taking, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors. 
     In accordance with some embodiments, a method is performed at an electronic device with a display, radio frequency (RF) circuitry for wirelessly communicating with one or more peripheral devices, and one or more input devices for receiving inputs from a user. The device displays a first user interface on the display. While displaying the first user interface, the device detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the device determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the device displays a pairing affordance that, when activated by a user input, initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays information concerning coupling of the first peripheral and the second peripheral. 
     In accordance with some embodiments, an electronic device includes a display, radio frequency (RF) circuitry for wirelessly communicating with one or more peripheral devices, one or more input devices for receiving inputs from a user, and a processing unit coupled to the display unit, the radio frequency (RF) circuitry, and the one or more input devices. The processing unit enables display of a first user interface on the display unit. While displaying the first user interface, the processing unit detects a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the processing unit determines whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the processing unit enables display of a pairing affordance that, when activated by a user input, initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the processing unit enables display of information concerning coupling of the first peripheral and the second peripheral. 
     Thus, electronic devices with displays, radio frequency (RF) circuitry, and one or more input devices are provided with faster, more efficient methods and interfaces for pairing with peripheral devices and displaying status information concerning the peripheral devices, thereby increasing the effectiveness, efficiency, and user satisfaction with such devices. Such methods and interfaces may complement or replace conventional methods for pairing peripherals.

     DESCRIPTION OF EMBODIMENTS 
     Many conventional electronic devices have the capability to pair with peripherals. However, when two or more peripherals are related (e.g., two earbuds or two earbuds and a case for the earbuds), conventional electronic devices typically need to pair individually with each peripheral before use. In contrast, as described herein, related peripherals can be paired simultaneously to a given device, thereby providing the capability to synchronize pairing between multiple peripherals in response to a single pairing action. Providing improved pairing functionality to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to efficiently pair with multiple related peripherals in a single action, thereby reducing user mistakes when attempting to pair a given device to multiple related peripherals). Without this improved pairing process, the user would have to take additional steps to get the device to individually pair with different peripherals, to achieve the same functionality as described herein. Individually pairing a device with multiple peripherals can be a time-consuming process, and the user is more prone to making mistakes due to the increased number of user inputs required to complete the pairing process. 
     In addition, conventional electronic devices display little or no status information concerning the paired peripherals. However, as described herein, status information concerning the peripherals is displayed (e.g., one or more battery levels) when the peripherals are proximate to the device. Providing status information of the peripherals enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing access to information concerning the peripherals without the user having to physically inspect each peripheral), thereby enabling the user to use the device and the peripherals more quickly and efficiently. 
     Below,  FIGS. 1A-1B, 2, 3 and 7  provide a description of example devices.  FIGS. 4A-4B and 5A-5Z  illustrate example user interfaces for selectively pairing the peripherals with an example device and selectively displaying status information concerning the peripherals on the example device.  FIGS. 6A-6C  are flow diagrams illustrating a method of pairing an electronic device with peripheral devices and displaying status information concerning the peripheral devices. The user interfaces in  FIGS. 5A-5Z  are used to illustrate the processes in  FIGS. 6A-6C .

     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. Example embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. 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.

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. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display system  112  is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. 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 or control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more 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 “tactile output” is 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. 1A  are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits. 
     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. Access to memory  102  by other components of device  100 , such as CPU(s)  120  and the peripherals interface  118 , is, optionally, controlled by memory controller  122 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU(s)  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(s)  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. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG. 2 ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch-sensitive display system  112  and other input or control devices  116 , with peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices.

The other input or control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG. 2 ). 
     Touch-sensitive display system  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch-sensitive display system  112 . Touch-sensitive display system  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user interface objects. As used herein, the term “affordance” is a user-interactive graphical user interface object (e.g., a graphical user interface object that is configured to respond to inputs directed toward the graphical user interface object). Examples of user-interactive graphical user interface objects include, without limitation, a button, slider, icon, selectable menu item, switch, hyperlink, or other user interface control. 
     Touch-sensitive display system  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-sensitive display system  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-sensitive display system  112  and converts 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-sensitive display system  112 . In an example embodiment, a point of contact between touch-sensitive display system  112  and the user corresponds to a finger of the user or a stylus. 
     Touch-sensitive display system  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-sensitive display system  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-sensitive display system  112 . In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif. 
     Touch-sensitive display system  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system  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 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-sensitive display system  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Optical sensor(s)  164  optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s)  164  receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor(s)  164  optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch-sensitive display system  112  on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.). 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled with intensity sensor controller  159  in I/O subsystem  106 .

Contact intensity sensor(s)  165  receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch-screen display system  112  which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled with peripherals interface  118 . Alternately, proximity sensor  166  is coupled with input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch-sensitive display system  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled with haptic feedback controller  161  in I/O subsystem  106 .

Tactile output generator(s)  167  receive 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-sensitive display system  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled with peripherals interface  118 . Alternately, accelerometer  168  is, optionally, coupled with an input controller  160  in I/O subsystem  106 . In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 .

     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 in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. 
     Contact/motion module  130  optionally detects contact with touch-sensitive display system  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 (e.g., by a finger or by a stylus), 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 stylus 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. 
     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 (lift off) 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 (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus. 
     In some embodiments, detecting a finger tap gesture depends on the length of time between detecting the finger-down event and the finger-up event, but is independent of the intensity of the finger contact between detecting the finger-down event and the finger-up event. In some embodiments, a tap gesture is detected in accordance with a determination that the length of time between the finger-down event and the finger-up event is less than a predetermined value (e.g., less than 0.1, 0.2, 0.3, 0.4 or 0.5 seconds), independent of whether the intensity of the finger contact during the tap meets a given intensity threshold (greater than a nominal contact-detection intensity threshold), such as a light press or deep press intensity threshold. Thus, a finger tap gesture can satisfy particular input criteria that do not require that the characteristic intensity of a contact satisfy a given intensity threshold in order for the particular input criteria to be met. For clarity, the finger contact in a tap gesture typically needs to satisfy a nominal contact-detection intensity threshold, below which the contact is not detected, in order for the finger-down event to be detected. A similar analysis applies to detecting a tap gesture by a stylus or other contact. In cases where the device is capable of detecting a finger or stylus contact hovering over a touch sensitive surface, the nominal contact-detection intensity threshold optionally does not correspond to physical contact between the finger or stylus and the touch sensitive surface. 
     The same concepts apply in an analogous manner to other types of gestures. For example, a swipe gesture, a pinch gesture, a depinch gesture, and/or a long press gesture are optionally detected based on the satisfaction of criteria that are either independent of intensities of contacts included in the gesture, or do not require that contact(s) that perform the gesture reach intensity thresholds in order to be recognized. For example, a swipe gesture is detected based on an amount of movement of one or more contacts; a pinch gesture is detected based on movement of two or more contacts towards each other; a depinch gesture is detected based on movement of two or more contacts away from each other; and a long press gesture is detected based on a duration of the contact on the touch-sensitive surface with less than a threshold amount of movement. As such, the statement that particular gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met means that the particular gesture recognition criteria are capable of being satisfied if the contact(s) in the gesture do not reach the respective intensity threshold, and are also capable of being satisfied in circumstances where one or more of the contacts in the gesture do reach or exceed the respective intensity threshold. In some embodiments, a tap gesture is detected based on a determination that the finger-down and finger-up event are detected within a predefined time period, without regard to whether the contact is above or below the respective intensity threshold during the predefined time period, and a swipe gesture is detected based on a determination that the contact movement is greater than a predefined magnitude, even if the contact is above the respective intensity threshold at the end of the contact movement. Even in implementations where detection of a gesture is influenced by the intensity of contacts performing the gesture (e.g., the device detects a long press more quickly when the intensity of the contact is above an intensity threshold or delays detection of a tap input when the intensity of the contact is higher), the detection of those gestures does not require that the contacts reach a particular intensity threshold so long as the criteria for recognizing the gesture can be met in circumstances where the contact does not reach the particular intensity threshold (e.g., even if the amount of time that it takes to recognize the gesture changes). 
     Contact intensity thresholds, duration thresholds, and movement thresholds are, in some circumstances, combined in a variety of different combinations in order to create heuristics for distinguishing two or more different gestures directed to the same input element or region so that multiple different interactions with the same input element are enabled to provide a richer set of user interactions and responses. The statement that a particular set of gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met does not preclude the concurrent evaluation of other intensity-dependent gesture recognition criteria to identify other gestures that do have a criteria that is met when a gesture includes a contact with an intensity above the respective intensity threshold. For example, in some circumstances, first gesture recognition criteria for a first gesture—which do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met—are in competition with second gesture recognition criteria for a second gesture—which are dependent on the contact(s) reaching the respective intensity threshold. In such competitions, the gesture is, optionally, not recognized as meeting the first gesture recognition criteria for the first gesture if the second gesture recognition criteria for the second gesture are met first. For example, if a contact reaches the respective intensity threshold before the contact moves by a predefined amount of movement, a deep press gesture is detected rather than a swipe gesture. Conversely, if the contact moves by the predefined amount of movement before the contact reaches the respective intensity threshold, a swipe gesture is detected rather than a deep press gesture. Even in such circumstances, the first gesture recognition criteria for the first gesture still do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met because if the contact stayed below the respective intensity threshold until an end of the gesture (e.g., a swipe gesture with a contact that does not increase to an intensity above the respective intensity threshold), the gesture would have been recognized by the first gesture recognition criteria as a swipe gesture. As such, particular gesture recognition criteria that do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met will (A) in some circumstances ignore the intensity of the contact with respect to the intensity threshold (e.g. for a tap gesture) and/or (B) in some circumstances still be dependent on the intensity of the contact with respect to the intensity threshold in the sense that the particular gesture recognition criteria (e.g., for a long press gesture) will fail if a competing set of intensity-dependent gesture recognition criteria (e.g., for a deep press gesture) recognize an input as corresponding to an intensity-dependent gesture before the particular gesture recognition criteria recognize a gesture corresponding to the input (e.g., for a long press gesture that is competing with a deep press gesture for recognition).

     Each of the above identified modules and applications correspond 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 (i.e., 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 re-arranged in various embodiments. 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. 1B  is a block diagram illustrating example components for event handling in accordance with some embodiments. In some embodiments, memory  102  (in  FIG. 1A ) 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  136 ,  137 - 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 system  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 system  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 system  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, peripheral 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 system  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 (i.e., 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, 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 module  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  includes 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 lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (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 system  112 , and lift-off 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 system  112 , when a touch is detected on touch-sensitive display system  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  145 . 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 touch-pads; 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 (e.g., touch-sensitive display system  112 ,  FIG. 1A ) 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 includes 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 the touch-screen display. 
     In some embodiments, device  100  includes the touch-screen display, 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 , head set 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 some embodiments, 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-sensitive display system  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 example 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 (CPU&#39;s)  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. 1A ), 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. 1A ). 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. 1A ), 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. 1A ) 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 (i.e., 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 re-arranged 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 (“UI”) that are, optionally, implemented on portable multifunction device  100 . 
       FIG. 4A  illustrates an example user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and       

     Wi-Fi signals;
         Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Map;”   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, which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely examples. For example, in some embodiments, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an example 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 . Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  357 ) for detecting intensities of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
       FIG. 4B  illustrates an example 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 . Although many of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 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. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) 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, etc.), 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 a 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. 
     As used herein, the term “focus selector” is 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. 4B ) 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. 1A  or the touch screen in  FIG. 4A ) 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). 
     User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device  100  or device  300 , with a display, radio frequency (RF) circuitry for wirelessly communicating with one or more peripheral devices, one or more input devices for receiving inputs from a user (e.g., a touch-sensitive surface), and (optionally) one or more sensors to detect intensities of contacts with the touch-sensitive surface. 
       FIGS. 5A-5Z  illustrate example user interfaces for pairing an electronic device with peripheral devices and displaying status information concerning the peripheral devices in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 6A-6C . For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system  112 . In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 . However, analogous operations are, optionally, performed on a device with a display  450  and a separate touch-sensitive surface  451  in response to detecting the contacts on the touch-sensitive surface  451  while displaying the user interfaces shown in the figures on the display  450 , along with a focus selector. 
       FIG. 5A  illustrates an example user interface on the display  112  of device  100 . While displaying the user interface, the device  100  periodically and repeatedly listens for wireless broadcast signals (e.g., pairing requests) from one or more peripherals (e.g., earbuds  502 - 1  and  502 - 2 , as well as earbud case  502 - 3 ) to pair the peripheral(s) with the device  100 . In some embodiments, as illustrated throughout  FIGS. 5A-5Z , the device  100  can detect pairing requests from a peripheral when the peripheral is within a threshold distance  508  of the device  100  and cannot detect pairing requests from the peripheral when the peripheral is outside of the threshold distance  508 . For example, the bottom of  FIG. 5A  illustrates an example spatial relationship (e.g., physical distance) between the device  100  and earbuds  502 - 1  and  502 - 2  as well as earbud case  502 - 3 , where earbuds  502 - 1  and  502 - 2  as well as earbud case  502 - 3  are outside of the threshold distance  508  of the device  100 . In contrast,  FIG. 5B  illustrates where earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3  (referred to collectively as earbud set  503 ) are within a threshold distance  508  of the device  100 , where the device is capable of detecting pairing requests from the peripherals. (Note that earbuds are also referred to as earpods, earphones, and in-ear headphones.) 
       FIG. 5B  illustrates an example user interface, displayed subsequent to the user interface in  FIG. 5A , for initiating pairing of the device  100  with a peripheral (e.g. earbud  502 - 1 ). In  FIG. 5B , the device  100  detects a pairing request from a peripheral (e.g., earbud  502 - 1  shown in  FIG. 5A  and part of earbud set  503 ) within the threshold distance  508 . In response to detecting the pairing request from the earbud  502 - 1 , the device  100  determines whether the earbud  502 - 1  meets coupling criteria. In the example shown in  FIG. 5B , the coupling criteria are met when an earbud  502 - 1  is placed within and/or electrically coupled to an earbud case  502 - 3  to form earbud set  503 . After the device  100  determines that the earbud  502 - 1  meets coupling criteria, the device  100  displays a window  520 - 1  overlaid on the first user interface that shows the earbud set  503 . The window  520 - 1  includes a “Connect” button  522 - 1 , that, when activated by a user input (e.g., a tap gesture), initiates pairing of the device  100  with the peripherals (e.g., earbuds  502 - 1  and  502 - 2  and earbud case  502 - 3  shown in  FIG. 5A ) of earbud set  503 . 
       FIGS. 5C-5E  illustrate an example user interface, displayed subsequent to the user interface in  FIG. 5B , for initiating pairing of a peripheral (e.g., earbud  502 - 1  of earbud set  503 ) with the device  100 . In  FIG. 5C , the device  100  detects a tap gesture  530 - 1  on the button  522 - 1 . In response to detecting the tap gesture  530 - 1 , the device  100  initiates pairing of the device  100  with the peripherals of earbud set  503 . In  FIG. 5D , while the device  100  is pairing with the peripherals of earbud set  503 , the device  100  displays a “Connect . . . ” notification graphic  523 - 1  in window  520 - 1 . In  FIG. 5E , after the device  100  pairs with the peripherals of earbud set  503 , the device  100  displays status information including a battery level graphic  526 - 1  indicating the battery level of the earbuds  502 - 1  and  502 - 2  and a battery level graphic  526 - 2  indicating the battery level of the earbud case  502 - 3 , in the window  520 - 1 . The device  100  also displays a “Done” button  524 - 1  that, when activated by a user input, such as a tap gesture, ceases display of the window  520 - 1  and allows the user to perform other conventional operations on device  100 . In some embodiments, window  520 - 1  ceases to be displayed after a predetermined period of time, even if the “Done” button is not activated. 
       FIG. 5F  illustrates an example user interface, displayed subsequent to the user interface in  FIG. 5A , for displaying information concerning pairing the device  100  with a peripheral (e.g. earbud  502 - 1 ) when coupling criteria are not met. In  FIG. 5F , the device  100  detects a pairing request from earbud  502 - 1  within the threshold distance  508 . In response to detecting the pairing request from the earbud  502 - 1 , the device  100  determines whether the earbud  502 - 1  meets coupling criteria. In the example shown in  FIG. 5F , coupling criteria are not met when an earbud  502 - 1  is not placed within and/or not electrically coupled to an earbud case  502 - 3 . Two different examples where earbud  502 - 1  does not meet coupling criteria are illustrated at the bottom of  FIG. 5F . In the bottom left portion of  FIG. 5F , earbud  502 - 1  and earbud case  502 - 3  are within the threshold distance  508  while earbud  502 - 2  is not within the threshold distance  508 . In the bottom right portion of  FIG. 5F , earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3  are all within the threshold distance  508 . However, in both example embodiments, earbud  502 - 1  is not placed within nor electrically coupled to the earbud case  502 - 3  and therefore does not meet the coupling criteria. After the device  100  determines that the earbud  502 - 1  does not meet coupling criteria, the device  100  displays a window  520 - 2  overlaid on the first user interface that displays information concerning coupling the earbud  502 - 1  (and, optionally, earbud  502 - 2 ) to the case  502 - 3 , such as a graphic directing the user to “Place Earpods in Case” and “Make sure both earpods are in the case!”). After the earbud  502 - 1  meets the coupling criteria (e.g., after earbud  502 - 1  is placed in the earbud case  502 - 3 , as shown in  FIG. 5B ) the device  100  displays a user interface like that shown in  FIG. 5B  for pairing the device  100  with the earbud set  503 . 
       FIG. 5G  illustrates an example user interface, displayed subsequent to the user interface in  FIG. 5E , for displaying certain status information concerning a peripheral after the peripheral has previously paired with the device  100 . In  FIG. 5G , the device  100  detects a pairing request from earbud  502 - 1 . After detecting the pairing request, the device  100  displays a window  520 - 3  overlaid on the user interface. The window  520 - 3  includes a battery level graphic  526 - 3  concerning the earbud  502 - 1 . In this example, the earbud  502 - 1  is designated as user Emily&#39;s left earbud by a graphic (e.g., “L”) displayed in the window  520 - 3 . In other examples, an earbud can be designated as a right earbud by displaying another graphic (e.g., the “R” graphic shown for earbud  502 - 2  in  FIG. 5H ). Also, as shown, the battery level graphic  526 - 3  concerning the earbud  502 - 1  illustrates a battery level of “50%”. 
       FIGS. 5H-5P  illustrate example user interfaces, displayed subsequent to the user interface in  FIG. 5E , for displaying certain information concerning two or more peripherals after at least one peripheral has paired with the device  100 . 
     In  FIG. 5H , the device  100  detects a pairing request from each of earbuds  502 - 1  and  502 - 2 . After detecting the pairing requests, the device  100  determines that the earbuds  502 - 1  and  502 - 2  are part of a predefined set because, for example, both earbuds  502 - 1  and  502 - 2  have previously paired with the device  100  in a single pairing process. In response to determining that the earbuds  502 - 1  and  502 - 2  are part of a predefined set, the device  100  displays a window  520 - 4  overlaid on the user interface. The window  520 - 4  displays a battery level graphic  526 - 4  illustrating a battery level of “50%” for earbud  502 - 1  and a battery level graphic  526 - 5  illustrating a battery level of “100%” for earbud  502 - 2 . 
     In  FIG. 5I , the device  100  detects a pairing request from earbuds  502 - 4  and  502 - 5  as well as earbud case  502 - 3 . Earbuds  502 - 4  and  502 - 5  are shown in thick black lines in the bottom of  FIG. 5I  to illustrate that these earbuds have not previously paired with the device  100  to form part of a predefined set. After detecting the pairing requests, the device  100  determines that the earbuds  502 - 4  and  502 - 5  are not part of a predefined set because, for example, both earbuds  502 - 4  and  502 - 5  have not been previously paired with the device  100 . In response to determining that the earbuds  502 - 4  and  502 - 5  are not part of a predefined set, the device  100  displays a window  520 - 5  overlaid on the user interface. The window  520 - 5  includes information concerning a mismatch between the earbuds  502 - 4  and  502 - 5  and the earbud case  502 - 3  because the earbuds  502 - 4  and  502 - 5  have not previously paired with the device  100  (as illustrated by a graphic such as “!” appearing adjacent to each of earbuds  502 - 4  and  502 - 5 ), while earbud case  502 - 3  has previously paired with the device  100 . The window  520 - 5  also includes a “Connect” button  522 - 2 , that, when activated by a user input (e.g., a tap gesture), initiates pairing of the earbuds  502 - 4  and  502 - 5  with the device  100 , in accordance with a determination that the earbuds  502 - 4  and  502 - 5  meet coupling criteria. 
       FIGS. 5J-5K  illustrate example user interfaces, displayed subsequent to the user interface in  FIG. 5E , for selectively displaying separate or combined status information for two or more peripherals based on status characteristics of the peripherals. In these examples, the device  100  detects a pairing request from each of earbuds  502 - 1  and  502 - 2 . After detecting the pairing requests, the device  100  determines that the earbuds  502 - 1  and  502 - 2  are part of a predefined set because, for example, both earbuds  502 - 1  and  502 - 2  have previously paired with the device  100  in a single pairing process. In response to determining that the earbuds  502 - 1  and  502 - 2  are part of a predefined set, the device  100  determines whether a difference in battery level (which is an example of a status characteristic) between the earbud  502 - 1  and earbud  502 - 2  exceeds or does not exceed a predetermined threshold (e.g., 10%). If the device  100  determines that the difference does not exceed the predetermined threshold, as shown in  FIG. 5J , the device  100  displays a window  520 - 6 , overlaid on the user interface, that includes combined status information for both of the earbuds  502 - 1  and  502 - 2  (e.g., displaying a single battery level graphic  526 - 6  of 50% for earbuds  502 - 1  and  502 - 2 ) in the window  520 - 4 . Conversely, if the device  100  determines that the difference exceeds the predetermined threshold, as shown in  FIG. 5K , the device  100  displays a window  520 - 7 , overlaid on the user interface, that includes separate status information for each of the earbuds  502 - 1  and  502 - 2  (e.g., displaying a battery level graphic  526 - 7  showing a battery level of 50% for earbud  502 - 1  and a separate battery level graphic  526 - 8  showing a battery level of 100% for earbud  502 - 2 ) in the window  520 - 5 . 
       FIGS. 5L-5P  illustrate alternative example user interfaces to the user interfaces displayed in  FIGS. 5H-5K . 
     In  FIG. 5L , after the device  100  detects a pairing request from at least one of earbuds  502 - 1  and  502 - 2  and earbud case  502 - 3  and determines that the earbuds  502 - 1  and  502 - 2  as well as earbud case  502 - 3  are part of a predefined set, the device  100  displays a window  520 - 8 , overlaid on the user interface, that includes status information of each of the earbuds  502 - 1  and  502 - 2  and earbud case  502 - 3  (e.g., displaying a battery level graphic  526 - 9  illustrating a battery level of 50% for earbud  502 - 1 , a battery level graphic  526 - 10  illustrating a battery level of 100% for earbud  502 - 2  and a battery level graphic  526 - 11  showing a battery level of 100% for earbud case  502 - 3 ) in the window  520 - 8 . 
       FIG. 5M  is similar to  FIG. 5L , except that device  100  determines that a battery level for earbud  502 - 1  falls below a minimum charge threshold. In response to determining that the battery level for earbud  502 - 1  falls below a minimum charge threshold, the device  100  displays a window  520 - 9 , overlaid on the user interface, that includes a low battery graphic  527  as status information of the earbud  502 - 1 . 
       FIG. 5N  is similar to  FIG. 5M , except that device  100  determines that earbuds  502 - 1  and  502 - 2  of  FIG. 5M  are coupled to earbud case  502 - 3  (which includes a power source for the earbuds) of  FIG. 5M  to form earbud set  503 . In response to determining that the earbuds  502 - 1  and  502 - 2  are coupled to a power source, the device  100  displays a window  520 - 10 , overlaid on the user interface, that includes status information illustrating the earbuds  502 - 1  and  502 - 2  are charging (e.g., a charging battery graphic  528 - 1  illustrating that earbuds  502 - 1  and  502 - 2  are charging and a battery level graphic  526 - 11  showing a battery level of 100% for earbud case  502 - 3 ). 
       FIG. 5O  is similar to  FIG. 5N , except that device  100  determines that earbud set  503  is coupled to an external power source  535  (e.g., a wall outlet). In response to determining that earbud set  503  is coupled to an external power source  535 , the device  100  displays a window  520 - 11 , overlaid on the user interface, that includes status information illustrating the earbuds  502 - 1  and  502 - 2  as well as earbud case  502 - 3  are charging (e.g., displaying a charging battery graphic  528 - 2  illustrating that earbud  502 - 1  is charging and has a battery level of 30%, a charging battery graphic  528 - 3  illustrating that earbud  502 - 2  is charging and has a battery level of 70%, and a charging battery graphic  528 - 4  illustrating that earbud case  502 - 3  is charging and has a battery level of 70%). 
       FIG. 5P  is similar to  FIG. 5I , except that earbud  502 - 1  has previously paired with device  100 , while earbud  502 - 5  has not previously paired with device  100 . After the device  100  detects a pairing request from earbuds  502 - 1  and  502 - 5  and determines that the earbuds  502 - 1  and  502 - 5  are not part of a predefined set, the device  100  displays a window  520 - 12  overlaid on the user interface. The window  520 - 12  includes information concerning a mismatch between the earbuds  502 - 1  and  502 - 5 , indicating to the user that the earbuds  502 - 1  and  502 - 5  are not part of a predefined set and need to be paired before being used. The window  520 - 12  also includes a “Connect” button  522 - 3 , that, when activated by a user input (e.g., a tap gesture), initiates pairing of the earbuds  502 - 1  and  502 - 5  with the device  100  to form a predefined set. 
       FIGS. 5Q-5Z  illustrate example user interfaces for pairing an electronic device with one or more peripherals and subsequently displaying status information concerning the peripheral(s) while the electronic device is in a locked state, in accordance with some embodiments. 
       FIG. 5Q  illustrates an example user interface on the display  112  of device  100  while the device  100  is in a locked state. In this example, while the device  100  is in the locked state, the example user interface is a lock screen. While displaying the lock screen, the device  100  repeatedly listens for pairing requests from peripherals, such as earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3 , to pair the peripheral with the device  100 . In this example, earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3  are outside of the threshold distance  508  of the device  100 . Therefore, the device  100  cannot detect a pairing request from earbud  502 - 1 , earbud  502 - 2  or earbud case  502 - 3 . 
       FIG. 5R  illustrates an example user interface, displayed subsequent to the user interface in  FIG. 5Q , for initiating pairing the device  100  with a peripheral (e.g. an earbud of earbud set  503 ). In  FIG. 5R , the device  100  detects a pairing request from an earbud of earbud set  503 , when the earbud set  503  is within the threshold distance  508 . In response to detecting the pairing request from the earbud, the device  100  determines whether the earbud meets coupling criteria. In this example, the coupling criteria are met when the earbud is placed within and/or electrically coupled to an earbud case to form earbud set  503 . After the device  100  determines that the earbud meets coupling criteria, the device  100  displays a window  520 - 13  overlaid on the first user interface that shows the earbud set  503 , which is within the threshold distance  508  of the device  100 . The window  520  also includes an “Unlock to Connect” button  522 - 4 , that, when activated by a user input (e.g., a tap gesture), initiates pairing of the device  100  with the peripherals (e.g., earbuds  502 - 1  and  502 - 2  and earbud case  502 - 3  shown in  FIG. 5Q ) of earbud set  503 . 
       FIG. 5S-5U  illustrate example user interfaces, displayed subsequent to the user interface in  FIG. 5R , for initiating pairing the device  100  with a peripheral based on a first authentication input (e.g., a finger input on fingerprint sensor  204 ). In  FIG. 5S , after the device  100  determines that the earbud  502 - 1  meets coupling criteria, the device  100  the device  100  detects a touch input  530 - 2  on the fingerprint sensor  204  (e.g., a stationary press or tap). In response to detecting a valid user authentication input by touch input  530 - 2 , the device  100  initiates pairing of the device  100  with the peripherals of earbud set  503 . In  FIG. 5T , while the device  100  is pairing the peripherals of earbud set  503 , the device  100  displays a “Connect . . . ” notification graphic  523 - 2  in window  520 - 13 . In  FIG. 5U , after the device  100  pairs with the earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3 , the device  100  displays status information (e.g., a charging battery graphic  528 - 5  illustrating that earbuds  502 - 1  and  502 - 2  are charging and a battery level graphic  526 - 12  showing a battery level of 100% for earbud case  502 - 3 ) in window  520 - 13 . The device  100  also displays a “Done” button  524 - 2  that, when activated by a user input, such as a tap gesture, ceases display of the window  520 - 13  and allows the user to perform other operations on device  100 . 
       FIGS. 5V-5Y  illustrate example user interfaces, displayed subsequent to the user interface in  FIG. 5R , for initiating pairing of the device  100  with a peripheral (e.g., an earbud of earbud set  503 ) based on a second authentication input (e.g., a passcode typed on a keypad). In  FIG. 5V , after the device  100  determines that the earbud of earbud set  503  meets coupling criteria, the device  100  detects a tap gesture  530 - 3  on the “Unlock to Connect” button  522 - 4 . In  FIG. 5W , in response to detecting the tap gesture  530 - 3 , the device  100  displays a user interface that includes a keypad  536  for authenticating the user. In this example, the keypad  536  is a numerical keypad having unique numerical inputs  537 - 1  to  537 - 9  that correspond to numerical values one (1) through nine (9), respectively. The device  100  then detects a user authentication input by a tap gesture  530 - 4  (e.g., a tap gesture) on one or more of the numerical inputs  537 - 1  to  537 - 9 . In response to the device  100  detecting a valid authentication input, the device  100  initiates pairing of the device  100  with the peripherals of earbud set  503 . In  FIG. 5X , while the device  100  is pairing with the earbud set  503 , the device  100  displays a “Connect . . . ” notification graphic  523 - 3  in window  520 - 13 . In addition, while the device  100  is pairing, the device  100  maintains display of the lock screen and continues to operate in a locked state. In  FIG. 5Y , as similarly shown in  FIG. 5U , after the device  100  pairs with the peripherals of earbud set  503 , the device  100  displays status information (e.g., displaying a charging battery graphic  528 - 6  illustrating that earbuds  502 - 1  and  502 - 2  of earbud set  503  are charging and a battery level graphic  526 - 13  showing a battery level of 100% for earbud case  502 - 3  of earbud set  503 ) in window  520 - 13 . The device  100  also displays a “Done” button  524 - 2  that, when activated by a user input, such as a tap gesture, ceases display of the window  520 - 13  and allows the user to perform other operations on device  100 . 
       FIG. 5Z  illustrates an example user interface, displayed subsequent to the user interfaces in  FIG. 5Y or 5U , for displaying certain status information concerning a peripheral after the peripheral has previously paired with the device  100 . In  FIG. 5Z , the device  100  detects a pairing request from earbud  502 - 1  and earbud  502 - 2 . After detecting the pairing request, the device  100  displays a window  520 - 14  overlaid on the user interface. The window  520 - 14  includes battery level graphic  526 - 14  (which is an example of status information) concerning the earbud  502 - 1  and the earbud  502 - 2 . As shown, the battery level graphic  526 - 14  concerning the earbuds  502 - 1  and  502 - 2  illustrates a battery level of “50%”. 
       FIGS. 6A-6C  are flow diagrams illustrating a method  600  of pairing an electronic device with peripheral devices and displaying status information concerning the peripheral devices in accordance with some embodiments. The method  600  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display, a radio frequency (RF) circuitry for wirelessly communicating with one or more peripheral devices, and one or more input devices (e.g., a touch-sensitive surface) for receiving inputs from a user. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  600  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  600  provides an intuitive way to pair peripherals with a device and display status information for the peripherals. The method reduces the number, extent, and/or nature of the inputs from a user when pairing peripherals with the device and displaying status information for the peripherals, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to pair peripherals with the device and display status information faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 602 ) a first user interface (e.g., a home screen, a user interface of an application, a wake screen, a lock screen, etc.) on the display. 
     While displaying the first user interface, the device detects ( 604 ) a pairing request to pair a first peripheral (e.g., earbuds  502 - 1  and  502 - 2 , an earbud case  502 - 3 , etc.) with the electronic device. In some embodiments, the pairing request is detected when a user touches the electronic device with one or both of the earbuds or with the case of the earbuds, or brings the electronic device and the earbuds within a threshold distance of each other. In some embodiments, the electronic device detects the presence and proximity of the earbud(s) or the case of the earbuds through wireless signals (e.g., broadcast Bluetooth signals, or a Bluetooth pairing request) emitted by the earbud(s) or the case of the earbuds. In some embodiments, the electronic device detects the presence and proximity of the earbud(s) or the case of the earbuds through other proximity sensing mechanisms (e.g., other RF signals sensing mechanisms) embedded in the electronic device and the earbuds and/or the case of the earbuds. 
     In some embodiments, detecting the pairing request to pair the first peripheral with the electronic device includes ( 606 ) detecting wireless signals transmitted from the first peripheral device and determining that the first peripheral device satisfies proximity criteria based on the detected wireless signals. In some embodiments, proximity criteria includes a criterion that is met when a signal strength of a wireless signal from the first peripheral exceeds a signal strength threshold. In some embodiments, proximity criteria includes a criterion that is met when the electronic device and the earbuds are within a threshold distance of each other. For example, as shown in  FIG. 5F , a first peripheral (e.g., earbud  502 - 1 ) is within a threshold distance  508  of electronic device  100 . 
     In response to detecting the pairing request, the device determines ( 608 ) whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled (e.g., electrically, magnetically, and/or wirelessly) to a second peripheral. The second peripheral is distinct from the electronic device, and both the first and the second peripherals are peripheral to the electronic device. In some embodiments, the first peripheral is an earbud (e.g., earbud  502 - 1 ) and the second peripheral is an earbud case (e.g., earbud case  502 - 3 ) for storing and charging the first earbud, as shown in  FIG. 5B  (as part of earbud set  503 ); and the coupling criteria require that the earbud and the case are in proximity to each other (e.g., the earbud is in the case and optionally electrically connected to the case) and to the electronic device. In some embodiments, the first peripheral is an earbud (e.g., earbud  502 - 1 ) and the second peripheral is a second earbud (e.g., earbud  502 - 2 ); and the coupling criteria require that the first earbud and the second earbud be coupled to each other through the case (e.g., earbud case  502 - 3 ). For example, both earbuds are electrically connected to the case (e.g., when placed inside the case with the lid closed). In some embodiments, the first peripheral is a first earbud and the second peripheral is a second earbud, the coupling criteria require that the first earbud and the second earbud are in proximity to each other and to the device (e.g., both the first and second earbuds are stored in the earbud case or placed near each other without the case). In some embodiments, the first peripheral is the case of the earbud and the second peripheral is an earbud or both of the earbuds; and the coupling criteria require that the earbud(s) and the case are coupled to each other or are placed in proximity to each other and to the device. 
     In some embodiments, the coupling criteria include ( 610 ) a criterion that is met when the first peripheral is coupled (e.g., electrically, magnetically, and/or wirelessly) to a third peripheral, distinct from the second peripheral. In some embodiments, the first peripheral is an earbud, the second peripheral is another earbud, the third peripheral is a case of the earbud, and the coupling criteria require that the first earbud and the second earbud be electrically coupled to each other through the earbud case. For example, as shown in  FIG. 5B , earbud  502 - 1 , earbud  502 - 2  and earbud case  502 - 3  are all coupled to form earbud set  503 . 
     In some embodiments, the first peripheral is ( 612 ) one or more earbuds and the second peripheral is a case for the one or more earbuds. 
     In some embodiments, the coupling criteria include ( 614 ) a criterion that is met when the one or more earbuds are at least one of: inside the case, and electrically coupled to the case. In some embodiments, as shown in  FIG. 5B , earbuds  502 - 1  and  502 - 2  are inside of, and electrically coupled to, earbud case  502 - 3  to form earbud set  503 . In some embodiments, the coupling criteria include an additional criterion that is met when the lid of the case is closed. 
     In accordance with a determination that the first peripheral meets the coupling criteria, the device displays ( 616 ) a pairing affordance (e.g., a button or other icon (e.g., “Connect” button  522 - 1 ) in a window (e.g., window  520 - 1 ) overlaid on the first user interface, as shown in  FIG. 5B ) that, when activated by a user input, initiates pairing of the electronic device with the first peripheral In some embodiments, the pairing affordance, when activated by the user input, also initiates pairing with the second peripheral (and any other peripherals that are coupled to the first and/or second peripheral). 
     In accordance with a determination that the first peripheral does not meet the coupling criteria, the device displays ( 618 ) information concerning coupling of the first peripheral and the second peripheral (e.g., the graphical display in window  520 - 2 , as shown in  FIG. 5F ). 
     Selectively pairing related peripherals, such as when the peripherals are coupled to other peripherals, provides the user with the capability to synchronize pairing between multiple peripherals in response to a single pairing action. Providing improved pairing functionality to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to efficiently pair a given device with multiple related peripherals in response to a single action, thereby reducing user mistakes when attempting to pair a given device to multiple related peripherals). Without this improved pairing process, the user would have to take additional steps to get the device to individually pair with different peripherals to achieve the same functionality as described herein. Individually pairing a device with multiple peripherals can be a time-consuming process, and the user is more prone to making mistakes due to the increased number of user inputs required to complete the pairing process. 
     In some embodiments, after the electronic device is paired with the first peripheral, the device displays ( 620 ) status information (e.g., model, manufacturer, icon, color, and/or battery level) concerning the first peripheral and the second peripheral in a second user interface. For example, as shown in  FIG. 5H , the first peripheral is earbud  502 - 1 , the second peripheral is earbud  502 - 2  and the second user interface is window  520 - 4 . Window  520 - 4  displays battery level graphic  526 - 4  for earbud  502 - 1  and battery level graphic  526 - 5  for earbud  502 - 2 . 
     Displaying status information concerning peripherals, after the peripherals pair with the device, provides the user with information concerning the peripherals (e.g., one or more battery levels) when the peripherals are proximate to the device. Providing status information of the peripherals enhances the operability of the device and makes the user-device interface more efficient (e.g., by providing access to information concerning the peripherals without the user having to physically inspect each peripheral), thereby enabling the user to use the device and peripherals more quickly and efficiently. 
     In some embodiments, after pairing of the electronic device with the first peripheral, the device determines ( 622 ) whether the second peripheral and the first peripheral are part of a predefined set of associated peripherals that have been previously paired with the electronic device. For example, when the electronic device has been previously paired with a set of earbuds and their case in a single pairing process (e.g., as illustrated in  FIGS. 5C-5E ), the electronic device stores a pairing profile that defines the set of earbuds and their case as a set of associated peripherals. In some embodiments, if one set of associated peripherals includes two earbuds and a case, and another set of associated peripherals includes a set of speakers, the speakers and the earbuds do not belong to the same set of associated peripherals, because they were not paired with the electronic device in a single pairing process. In some embodiments, the first and second peripherals are part of a predefined set when the first and second peripherals have been previously paired to the electronic device in a single pairing process. In accordance with a determination that the second peripheral and the first peripheral are part of a predefined set of associated peripherals that have been previously paired with the electronic device, the device displays status information (e.g., model, manufacturer, icon, color, and/or battery level) concerning the first peripheral and the second peripheral (e.g., as illustrated in  FIGS. 5H and 5J-5O ). In some embodiments, corresponding graphics may be displayed to illustrate a peripheral heuristic (e.g., a graphic showing the case lid open). In accordance with a determination that the second peripheral and the first peripheral are not part of a predefined set of associated peripherals that have been previously paired with the electronic device, the device displays information concerning a mismatch between the first peripheral and the second peripheral (e.g., as illustrated in  FIGS. 5I and 5P ). 
     Displaying information concerning whether two or more peripherals have been previously paired with a device during a single pairing process, and therefore form a set of associated peripherals, provides the user with the capability to quickly discern whether the peripherals are available for immediate use, or whether the peripherals need to be paired together before use. Providing improved pairing functionality of multiple peripherals to a given device enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to quickly understand when peripherals are available for use or, alternatively, when the peripherals need to be paired together with the device before use). Without this information, the user might mistakenly attempt to use peripherals that are not part of a predetermined set (e.g., by using one or more unpaired earbuds and trying to stream media content from the device to the earbuds), and subsequently discover that at least one of the peripherals is inoperable with the device. 
     In some embodiments, displaying information concerning the mismatch between the first peripheral and the second peripheral includes ( 624 ) displaying a second pairing affordance (e.g., a button or other icon (e.g., “Connect” button  522 - 2 ) in a window (e.g., window  520 - 5 ) overlaid on the first user interface, as shown in  FIG. 5I ) that, when activated by a user input, initiates pairing of the electronic device with the second peripheral. In some embodiments, the second pairing affordance, when activated by the user input, also initiates pairing with any other peripherals that are coupled to the first and/or second peripheral. 
     In some embodiments, displaying the status information (e.g., model, manufacturer, icon, color, and/or battery level) concerning the first peripheral and the second peripheral includes ( 626 ) displaying a single combined peripheral status characteristic (e.g., a combined battery level) concerning the first peripheral and the second peripheral in accordance with a determination that a difference between a first peripheral status characteristic (e.g., battery level) of the first peripheral and a second peripheral status characteristic (e.g., battery level) of the second peripheral is less than a predetermined threshold and the first peripheral and the second peripheral are the same type of peripheral (e.g., earbuds) (e.g., as shown in  FIGS. 5H and 5N .). In some embodiments, the predetermined threshold is a numerical difference of 5%, 10%, 15%, or 20%. 
     In some embodiments, displaying status information (e.g., model, manufacturer, icon, color, and/or battery level) concerning the first peripheral and the second peripheral includes ( 628 ) displaying a first peripheral status characteristic (e.g., battery level of the first peripheral) concerning the first peripheral and displaying a second peripheral status characteristic (e.g., battery level of the second peripheral) concerning the second peripheral in accordance with a determination that a difference between the first peripheral status characteristic (e.g., battery level) of the first peripheral and the second peripheral status characteristic (e.g., battery level) of the second peripheral is greater than a predetermined threshold and the first peripheral and the second peripheral are the same type of peripheral (e.g., earbuds) (e.g., as shown in  FIG. 5L ). In some embodiments, the predetermined threshold difference is 5%, 10%, 15%, or 20%. 
     In some embodiments, displaying the status information of the first peripheral includes ( 630 ) displaying a low battery graphic in accordance with a determination that a battery level concerning the first peripheral falls below a minimum charge threshold (e.g., as shown in  FIG. 5M ). In some embodiments, the minimum charge threshold is 10%, 15%, or 20%. 
     In some embodiments, displaying the status information of the first peripheral includes ( 632 ) displaying a charging battery graphic in accordance with a determination that a first peripheral is connected to a power source (e.g., as shown in  FIGS. 5N-5O ). In some embodiments, the power source is a battery or a wall outlet. In some embodiments, the first peripheral is an earbud and the power source is integrated in the second peripheral (e.g., a case). 
     In some embodiments, the electronic device is ( 634 ) in a locked state while displaying the first user interface (e.g., a lock screen, a wake screen for a locked state, etc. as shown in  FIGS. 5Q-5Y ). After activating the pairing affordance (e.g., “Connect” button  522 - 3  in window  520 - 12  of  FIG. 5V ), the device presents a request (e.g., on the display and/or aurally) for an authentication input (e.g., displaying a passcode keypad  536  as shown in  FIG. 5W ) from a user to pair the first peripheral with the electronic device. The device receives the authentication input from the user. In some embodiments, the received authentication input is the same input as an authentication input that unlocks the electronic device (e.g., fingerprint scan, passcode, slide gesture, etc.). In response to receiving the authentication input: the device pairs the first peripheral with the electronic device (e.g., as shown in  FIGS. 5X-5Y ) and maintains the electronic device in the locked state. 
     Providing pairing functionality between the device and the peripheral, while the device is in a locked state, enhances the operability of the device and makes the user-device interface more efficient by reducing the number of user inputs required to pair the device with the peripheral, thereby reducing user mistakes when operating/interacting with the device. 
     In some embodiments, the device maintains ( 636 ) display of the first user interface associated with the locked state of the electronic device while pairing the first peripheral with the electronic device. 
     In some embodiments, the device maintains ( 638 ) display of the first user interface associated with the locked state of the electronic device after pairing the first peripheral with the electronic device is completed. 
     In some embodiments, while maintaining display of the first user interface associated with the locked state of the electronic device after pairing the first peripheral with the electronic device is completed, the device displays ( 640 ) status information concerning the first peripheral (e.g., single earbud case, mismatch case, battery status cases, etc.) (e.g., as shown in window  520 - 13  of  FIG. 5Z ). 
     It should be understood that the particular order in which the operations in  FIGS. 6A-6C  have been described is merely an example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. 
     In accordance with some embodiments,  FIG. 7  shows a functional block diagram of an electronic device  700  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 7  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG. 7 , an electronic device  700  includes a display unit  702  configured to display a user interface; an RF circuitry unit  704  for wirelessly communicating with one or more peripheral devices; one or more input device units  706  for receiving inputs from a user; and a processing unit  708  coupled to the display unit  702 , the RF circuitry unit  704 , and the one or more input device units  706 . The processing unit  708  includes display enabling unit  710 , detecting unit  712 , determining unit  714 , presenting unit  716 , receiving unit  718 , pairing unit  720 , and maintaining unit  722 . 
     The processing unit  708  is configured to: enable display of (e.g., with display enabling unit  710 ) a first user interface on the display unit  702 . While displaying the first user interface, the processing unit  708  is configured to detect (e.g., with detecting unit  712 ) a pairing request to pair a first peripheral with the electronic device. In response to detecting the pairing request, the processing unit  708  is configured to determine (e.g., with determining unit  714 ) whether the first peripheral meets coupling criteria, wherein the coupling criteria require that the first peripheral is coupled to a second peripheral. In accordance with a determination that the first peripheral meets the coupling criteria, the processing unit  708  is configured to enable display of (e.g., with display enabling unit  710 ) a pairing affordance that, when activated by a user input, initiates pairing of the electronic device with the first peripheral. In accordance with a determination that the first peripheral does not meet the coupling criteria, the processing unit  708  is configured to enable display of (e.g., with display enabling unit  710 ) information concerning coupling of the first peripheral and the second peripheral. 
     In some embodiments, detecting the pairing request to pair the first peripheral with the electronic device includes detecting wireless signals transmitted from the first peripheral device and determining that the first peripheral device satisfies proximity criteria based on the detected wireless signals. 
     In some embodiments, the coupling criteria include a criterion that is met when the first peripheral is coupled to a third peripheral, distinct from the second peripheral. 
     In some embodiments, the first peripheral is one or more earbuds and the second peripheral is a case for the one or more earbuds. 
     In some embodiments, the coupling criteria include a criterion that is met when the one or more earbuds are at least one of: inside the case, and electrically coupled to the case. 
     In some embodiments, the processing unit  708  is configured to, after the electronic device is paired with the first peripheral, enable display of (e.g., with display enabling unit  710 ) status information concerning the first peripheral and the second peripheral in a second user interface. 
     In some embodiments, the processing unit  708  is configured to, after pairing of the electronic device with the first peripheral, determine (e.g., with determining unit  714 ) whether the second peripheral and the first peripheral are part of a predefined set of associated peripherals that have been previously paired with the electronic device. In accordance with a determination that the second peripheral and the first peripheral are part of a predefined set of associated peripherals that have been previously paired with the electronic device, the processing unit  708  is configured to enable display of (e.g., with display enabling unit  710 ) status information concerning the first peripheral and the second peripheral. In accordance with a determination that the second peripheral and the first peripheral are not part of a predefined set of associated peripherals that have been previously paired with the electronic device, the processing unit  708  is configured to enable display of (e.g., with display enabling unit  710 ) information concerning a mismatch between the first peripheral and the second peripheral. 
     In some embodiments, displaying information concerning the mismatch between the first peripheral and the second peripheral includes displaying a second pairing affordance that, when activated by a user input, initiates pairing of the electronic device with the second peripheral. 
     In some embodiments, displaying the status information concerning the first peripheral and the second peripheral includes displaying a single combined peripheral status characteristic concerning the first peripheral and the second peripheral in accordance with a determination that a difference between a first peripheral status characteristic of the first peripheral and a second peripheral status characteristic of the second peripheral is less than a predetermined threshold and the first peripheral and the second peripheral are the same type of peripheral. 
     In some embodiments, displaying status information concerning the first peripheral and the second peripheral includes displaying a first peripheral status characteristic concerning the first peripheral and displaying a second peripheral status characteristic concerning the second peripheral in accordance with a determination that a difference between the first peripheral status characteristic of the first peripheral and the second peripheral status characteristic of the second peripheral is greater than a predetermined threshold and the first peripheral and the second peripheral are the same type of peripheral. 
     In some embodiments, displaying the status information of the first peripheral includes displaying a low battery graphic in accordance with a determination that a battery level concerning the first peripheral falls below a minimum charge threshold. 
     In some embodiments, displaying the status information of the first peripheral includes displaying a charging battery graphic in accordance with a determination that a first peripheral is connected to a power source. 
     In some embodiments, the electronic device is in a locked state while displaying the first user interface, and the processing unit  708  is configured to, after activation of the pairing affordance, present (e.g., with presenting unit  716 ) a request for an authentication input from a user to pair the first peripheral with the electronic device; receive (e.g., with receiving unit  718 ) the authentication input from the user; and, in response to receiving the authentication input: pair (e.g., with pairing unit  720 ) the first peripheral with the electronic device; and maintain (e.g., with maintaining unit  722 ) the electronic device in the locked state. 
     In some embodiments, the processing unit  708  is configured to maintain (e.g., with maintaining unit  722 ) display of the first user interface associated with the locked state of the electronic device while pairing the first peripheral with the electronic device. 
     In some embodiments, the processing unit  708  is configured to maintain (e.g., with maintaining unit  722 ) display of the first user interface associated with the locked state of the electronic device after pairing the first peripheral with the electronic device is completed. 
     In some embodiments, the processing unit  708  is configured to, while maintaining display of the first user interface associated with the locked state of the electronic device after pairing the first peripheral with the electronic device is completed, enable display of (e.g., with display enabling unit  710 ) status information concerning the first peripheral. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 6A-6C  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 7 . For example, at least some functionality described in  FIGS. 6A-6C  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . 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. 1A-1B . 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best use the invention and various described embodiments with various modifications as are suited to the particular use contemplated.
