Title: Context-specific user interfaces

Abstract:
Context-specific user interfaces, e.g., for use with a portable multifunction device, provide, inter alia, indications of time and, optionally, a variety of additional information. A user interface screen including a current time indicator and a first platter is displayed. The first platter is at a first position, is associated with a first application, and displays a first set of information obtained from the first application. The first set of information relates to a first temporal context of the current day. In response to detecting a user input, the first platter is displayed at a second position and a second platter is displayed at the first position. The second platter is associated with a second application and displays a second set of information obtained from the second application. The second set of information relates to a second temporal context of the current day.

CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 15/798,235, entitled “Context-Specific User Interfaces,” filed Oct. 30, 2017, which claims priority to U.S. Provisional Patent Application Ser. No. 62/505,782, entitled “Context-Specific User Interfaces,” filed May 12, 2017, the contents of each of which are hereby incorporated by reference in their entirety. 
     This application relates to the following applications: International Patent Application Serial No. PCT/US2015/034604, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022203; International Patent Application Serial No. PCT/US2015/034606, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022204; and International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205. The content of these applications is hereby incorporated by reference in their entirety. 
    
    
     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for providing context-specific user interfaces. 
     BACKGROUND 
     Portable multifunction devices allow users to access information from a variety of applications and data sources on a reduced-size device they can keep with them throughout the day in a variety of contexts (e.g., at work, at home, while traveling, etc.). However, as context changes, the types of information a user may wish to view can also change. Thus, it is a challenge to provide an efficient interface that displays relevant information to a user throughout the day. For example, a user may wish to know the time of sunset, but a widget dedicated to sunset time is only relevant to a user as sunset approaches. The rest of the day, this screen “real estate” is providing irrelevant information and taking up space that could be used to provide more relevant information. This is a particular concern for portable devices with reduced-size interfaces. 
     SUMMARY 
     Users rely on portable multifunction devices for keeping time, among a variety of other operations including running software applications. However, some techniques for providing context-specific user interfaces (e.g., for keeping time and/or other operations) are generally cumbersome and inefficient. For example, some existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Some existing techniques require more multiple user interactions in order to display all of the information the user wishes to view. Existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present technique provides electronic devices with faster, more efficient methods and interfaces for providing context-specific user interfaces. Such methods and interfaces optionally complement or replace other methods for providing context-specific user interfaces. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges and reduce the number of unnecessary, extraneous, and/or repetitive received inputs required to access information. 
     In some embodiments, a method comprises at an electronic device with a display, one or more processors, and memory: displaying on the display a user interface screen comprising: a current time indicator; and a first platter at a first position on the display, wherein the first platter is associated with a first application and displays a first set of information obtained from the first application, wherein the first set of information relates to a first temporal context of the current day; detecting a user input; and in response to detecting the user input: displaying the first platter at a second position different from the first position on the display; and displaying a second platter at the first position on the display, wherein the second platter is associated with a second application and displays a second set of information obtained from the second application, wherein the second set of information relates to a second temporal context of the current day, and wherein the first and the second applications are different.

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for context-specific user interfaces, e.g., that display the time along with additional information. This is particularly true for portable multifunction devices with reduced-size displays. Providing the user with relevant information (e.g., obtained from one or more applications) at a glance in a convenient, customizable interface reduces the number of inputs needed to access the information and conserves battery life. Moreover, providing user interfaces that change displayed content as the context in which the user is using the interfaces changes (e.g., throughout the day) makes accessing such information through the interfaces even more efficient. An interface that changes the type of displayed information as a user&#39;s context changes provides more efficient use of screen “real estate,” which in turn reduces the number of user interactions required to access relevant data at any time of day. Such techniques can reduce the cognitive burden on a user who uses the context-specific user interfaces to access information and/or keep time. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5H  provide a description of exemplary devices for performing the techniques for configuring context-specific user interfaces.  FIGS. 6A-6V, 9A-9L, 11A-14E, 17A, 17B, and 19A-19F  illustrate exemplary user interfaces for providing context-specific user interfaces. The user interfaces in the figures are also used to illustrate the processes described below, including the processes in  FIGS. 7A-8G, 10A-10C, 15A-16D, and 18 . 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, 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. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG. 1A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     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. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth.

The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     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 screen  112  and other input control devices  116 , to 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 one or more input controllers  160  receive/send electrical signals from/to other input control devices  116 . The other input 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 to any (or none) of the following: a keyboard, an infrared port, a USB port, and 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 ). 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  is, optionally, coupled to an input controller  160  in I/O subsystem  106 . Accelerometer  168  optionally performs as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (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 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like.

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

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG. 3 ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG. 3 ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 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), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG. 5A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS. 1A-4B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG. 5B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS. 1A, 1B, and 3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including processes  700 ,  800 ,  1000 ,  1500 ,  1600 , and  1800  ( FIGS. 7A-8G, 10A-10C, 15A-16D, and 18 ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG. 5B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS. 1A, 3, and 5A-5B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG. 3  or touch-sensitive surface  451  in  FIG. 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 touch screen  112  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). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally, based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
       FIG. 5C  illustrates detecting a plurality of contacts  552 A- 552 E on touch-sensitive display screen  504  with a plurality of intensity sensors  524 A- 524 D.  FIG. 5C  additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors  524 A- 524 D relative to units of intensity. In this example, the intensity measurements of intensity sensors  524 A and  524 D are each 9 units of intensity, and the intensity measurements of intensity sensors  524 B and  524 C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors  524 A- 524 D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity.  FIG. 5D  illustrates assigning the aggregate intensity to contacts  552 A- 552 E based on their distance from the center of force  554 . In this example, each of contacts  552 A,  552 B, and  552 E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts  552 C and  552 D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to  FIGS. 5C-5D  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in  FIGS. 5C-5D  to aid the reader. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm is, optionally, applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
       FIGS. 5E-5H  illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact  562  from an intensity below a light press intensity threshold (e.g., “IT L ”) in  FIG. 5E , to an intensity above a deep press intensity threshold (e.g., “IT D ”) in  FIG. 5H . The gesture performed with contact  562  is detected on touch-sensitive surface  560  while cursor  576  is displayed over application icon  572 B corresponding to App  2 , on a displayed user interface  570  that includes application icons  572 A- 572 D displayed in predefined region  574 . In some embodiments, the gesture is detected on touch-sensitive display  504 . The intensity sensors detect the intensity of contacts on touch-sensitive surface  560 . The device determines that the intensity of contact  562  peaked above the deep press intensity threshold (e.g., “IT D ”). Contact  562  is maintained on touch-sensitive surface  560 . In response to the detection of the gesture, and in accordance with contact  562  having an intensity that goes above the deep press intensity threshold (e.g., “IT D ”) during the gesture, reduced-scale representations  578 A- 578 C (e.g., thumbnails) of recently opened documents for App  2  are displayed, as shown in  FIGS. 5F-5H . In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact  562  is not part of a displayed user interface, but is included in  FIGS. 5E-5H  to aid the reader. 
     In some embodiments, the display of representations  578 A- 578 C includes an animation. For example, representation  578 A is initially displayed in proximity of application icon  572 B, as shown in  FIG. 5F . As the animation proceeds, representation  578 A moves upward and representation  578 B is displayed in proximity of application icon  572 B, as shown in  FIG. 5G . Then, representations  578 A moves upward,  578 B moves upward toward representation  578 A, and representation  578 C is displayed in proximity of application icon  572 B, as shown in  FIG. 5H . Representations  578 A- 578 C form an array above icon  572 B. In some embodiments, the animation progresses in accordance with an intensity of contact  562 , as shown in  FIGS. 5F-5G , where the representations  578 A- 578 C appear and move upwards as the intensity of contact  562  increases toward the deep press intensity threshold (e.g., “IT D ”). In some embodiments, the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to FIGS.  5 E- 5 H can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     As used herein, an “installed application” refers to a software application that has been downloaded onto an electronic device (e.g., devices  100 ,  300 , and/or  500 ) and is ready to be launched (e.g., become opened) on the device. In some embodiments, a downloaded application becomes an installed application by way of an installation program that extracts program portions from a downloaded package and integrates the extracted portions with the operating system of the computer system. 
     As used herein, the terms “open application” or “executing application” refer to a software application with retained state information (e.g., as part of device/global internal state  157  and/or application internal state  192 ). An open or executing application is, optionally, any one of the following types of applications:
         an active application, which is currently displayed on a display screen of the device that the application is being used on;   a background application (or background processes), which is not currently displayed, but one or more processes for the application are being processed by one or more processors; and   a suspended or hibernated application, which is not running, but has state information that is stored in memory (volatile and non-volatile, respectively) and that can be used to resume execution of the application.       

     As used herein, the term “closed application” refers to software applications without retained state information (e.g., state information for closed applications is not stored in a memory of the device). Accordingly, closing an application includes stopping and/or removing application processes for the application and removing state information for the application from the memory of the device. Generally, opening a second application while in a first application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application. 
     Attention is now directed towards embodiments of providing context-specific user interfaces and associated processes that may be implemented on a portable multifunction device with a display and a touch-sensitive surface, such as devices  100 ,  300 , and/or  500  ( FIGS. 1A, 3 , and/or  5 A). 
     The following examples illustrate exemplary embodiments of context-specific user interfaces. Described herein are overall concepts related to interactive and/or customizable context-specific user interfaces. It is noted that the context-specific user interfaces described herein are editable in a number of ways. A user interface may display or otherwise indicate various types of information related to time, and the type(s) of information may be customizable by the user. A user interface may include aspects such as colors, density of display, and complications (or lack of complications) that are also customizable. As used here, consistent with its accepted meaning in art, a complication refers to any clock face feature other than those used to indicate the hours and minutes of a time (e.g., clock hands or hour/minute indications). Complications may provide different types of information to a user, such as data obtained from an application, and the information conveyed to a user by a complication is also customizable, as described below. In some embodiments, a complication may also serve as an affordance for launching an application. Additional descriptions of context-specific user interfaces, as well as features thereof and techniques related thereto (e.g., editing and/or selecting context-specific user interfaces), are found in International Patent Application Serial No. PCT/US2015/034604, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022203; International Patent Application Serial No. PCT/US2015/034606, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022204; and International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205; each of which is incorporated by reference herein in its entirety. 
     As described supra, users may wish to view different types of information in different contexts (e.g., throughout the day) using a portable multifunction device. Widgets dedicated to a particular application can display specific sets of information from the application, but if the user is not interested in that information or application at a particular time, the information is taking up screen “real estate” that could be used to provide more immediately relevant information. Therefore, providing application information based on temporal context, and/or not limited by the particular application from which the information is obtained, provides a more efficient interface that allows the user to view the right information at the right time, thereby reducing the number of inputs required to access the information, decreasing demands on battery life (e.g., to power the display), and making more efficient use of screen “real estate.” 
       FIGS. 6A-6V  show exemplary context-specific user interfaces that may be operated on device  600 . Device  600  may be device  100 ,  300 , or  500  in some embodiments. The electronic device has a display  602  (e.g.,  504 ). In some embodiments, display  602  is a touch-sensitive display. In some embodiments, device  600  includes rotatable input mechanism  610   a  (e.g.,  506 ) and/or input mechanism or button  610   b  (e.g.,  508 ). 
     In  FIG. 6A , device  600  displays a context-specific user interface on display  602 . This exemplary context-specific user interface includes current time indicator  604  (e.g., a digital clock). Indicator  604  can optionally include a variety of features or aspects that are independently editable or configurable by the user. 
     In addition, the context-specific user interface also includes complications  612   614 . In some embodiments, complications  612  and/or  614  obtain data and display information from one or more applications. In some embodiments, the displayed information can be updated, e.g., in accordance with updates to data obtained from the application. For example, as shown in  FIG. 6A , complication  612  can display information from a calendar application (e.g., date and/or day of the week). In some embodiments, complication  614  does not display information updated in accordance with updates to data obtained from the application, but rather displays a static representation of the application. 
     The user interface screen displayed in  FIG. 6A  also includes platters  606  and  608 . Platters  606  and  608  are each associated with an application. In this example, platter  606  is associated with a weather application, and platter  608  is associated with a calendar application. Platter  606  displays a set of information obtained from the weather application: the time of a predicted change in weather conditions or time of predicted inclement weather conditions, as well as textual and graphical indications of the weather conditions. Platter  608  displays a set of information obtained from the calendar application: the time of an upcoming calendar event, and indications of the event name and location. Platter  606  is displayed as larger and/or appearing closer to the user to emphasize its information (e.g., its temporal context (1:00-2:00 PM) is closer to the current time (10:09) than the temporal context of platter  608  (4:30-5:30 PM)). 
     Both platters  606  and  608  display information related to a temporal context of the current day. As used herein, a “temporal context” can relate to a time attached to a set of information by the user (e.g., the time of a calendar event), a time attached to a set of information by an external data source (e.g., the time of a predicted change in weather, based on data obtained from an external server), or a time attached to a set of information by an electronic device of the present disclosure (e.g., device  600 ). For example, as described in greater detail infra, device  600  can designate a time of day to surface a set of information to the user, such as a reminder to breathe or engage in exercise. 
     Platters  606  and  608  are selected by device  600  for display based, at least in part, on temporal context of the current day. Each represents a different application. Thus, information obtained from various applications can be presented to the user and optionally ordered by temporal context. This allows the user to view information obtained from one or more applications at a glance when it is relevant, rather than allocating screen “real estate” to dedicated information and/or applications that are not equally relevant throughout the day. In some embodiments, concurrently displayed platters can represent the same application (e.g., two platters representing sets of calendar application-related information related to different temporal contexts). 
     To view information related to later temporal contexts, the user rotates the rotatable input mechanism  610   a  (e.g., scroll  616   a ;  FIG. 6B ). Scroll indicator  618   a  is also displayed adjacent to  610   a  on display  602  to indicate to the user how many platters are displayable, and the position of the currently displayed platter(s) in a series of displayable platters. In some embodiments, scroll indicator  618   a  is displayed in response to detecting scroll  616   a , thereby indicating to the user that additional information can be viewed using rotational inputs through rotatable input mechanism  610   a.    
     In response to detecting scroll  616   a , as shown in  FIG. 6C , platters  606  and  608  are translated on-screen, and platter  608  now appears larger and/or closer to the user. In addition, platter  620  is displayed at the bottom of display  602 . Platter  620  is associated with a navigation application and displays a set of information obtained from the navigation application (e.g., the time of a predicted change in traffic conditions, such as a time of worsening predicted traffic or a typical time of day when the user is driving or taking public transportation). Platter  620  displays information related to a temporal context of the current day at the same time or later than the set of information shown in platter  608 . The scroll indicator (e.g.,  618   b ) is also updated to indicate the position of platter  608  in the series. In some embodiments, scroll indicator  618   b  is displayed in response to detecting scroll  616   a , thereby indicating to the user that additional information can be viewed using rotational inputs through rotatable input mechanism  610   a.    
     The user again rotates  610   a  (e.g., scroll  616   b ;  FIG. 6C ). In response to detecting scroll  616   b , device  600  ceases to display platter  606  and displays platter  608  at the former position of platter  606  (e.g., by translating  608  on-screen;  FIG. 6D ). In addition, platter  620  is displayed at the former position of platter  608  at a larger size and/or appearing closer to the user. In some embodiments, platter  620  displays additional information in this display position, such as the “leave now” text to let the user know that their commute home is predicted to be disrupted by traffic in 40 minutes. Platter  622 , associated with a news application, is displayed at the former position of platter  620 . The scroll indicator (e.g.,  618   c ) is also updated to indicate the position of platter  620  in the series. 
     The user again rotates  610   a  (e.g., scroll  616   c ;  FIG. 6D ). In response to detecting scroll  616   c , device  600  ceases to display platter  608  and displays platter  620  at the former position of platter  608  (e.g., by translating  620  on-screen;  FIG. 6E ). In addition, platter  622  is displayed at the former position of platter  620  at a larger size and/or appearing closer to the user. In some embodiments, platter  622  displays additional information in this display position, such as the top headline of the day. A partial view of platter  624 , representing tomorrow&#39;s calendar events, is also displayed. The scroll indicator (e.g.,  618   d ) is also updated to indicate the position of platter  622  in the series. 
     Platters  606 ,  608 ,  620 , and  622  display sets of information obtained from various applications that relate to temporal context(s) of the current day. Platter  624  indicates to the user that information related to the next day is also displayable. The user rotates  610   a  (e.g., scroll  616   d ;  FIG. 6E ), and in response to detecting scroll  616   d , the display is updated as shown in  FIG. 6F . In  FIG. 6F , device  600  ceases to display platter  620 , displays  622  in the former position of  620 , and displays a full view of platter  624 . Platter  624  is associated with the calendar application and displays information obtained therefrom: an indication of the number of calendar events scheduled for tomorrow, and the time of the first calendar event scheduled for tomorrow. A partial view of platter  626 , representing tomorrow&#39;s predicted weather, is also displayed. The scroll indicator (e.g.,  618   e ) is also updated to indicate the position of platter  624  in the series. 
     The user rotates  610   a  (e.g., scroll  618   e ;  FIG. 6F ) in order to view all of platters  624  and  626 . As shown in  FIG. 6G , platter  626  displays textual and graphical depictions of the weather conditions predicted for tomorrow, as well as the predicted high and low temperatures. The scroll indicator is also updated to indicate the position of platter  626  in the series (e.g.,  618   f ). In some embodiments, as shown in  FIG. 6G , platters  624  and  626  do not display sets of information related to discrete temporal contexts of tomorrow, but rather display information related to tomorrow generally, or related to multiple contexts of tomorrow. In some embodiments, platters associated with the current day display sets of information related to discrete temporal contexts of the current day (e.g., single calendar events or weather notifications), whereas platters associated with tomorrow display sets of information related to multiple temporal contexts of tomorrow or the majority of tomorrow (e.g., a summary of multiple calendar events or a summary of the entire day&#39;s weather). 
     In order to return to the current time view, the user taps display  602  (e.g., tap  628 ). In response to detecting tap  628 , device  600  displays ceases to display platters  624  and  626  and displays platters  606  and  608  ( FIG. 6H ). Indicator  618   a  is also updated accordingly to reflect the position of platter  606  along the series of displayable platters. In some embodiments, the user returns to the user interface screen shown in  FIG. 6H  by scrolling in the opposite direction (e.g., by rotating  610   a  through rotational inputs in the opposite directions of scrolls  616   a ,  616   b ,  616   c ,  616   d , and  616   e ). 
     In some embodiments, rather than scrolling the user interface screens by rotating  610   a , the user swipes display  602  to scroll the user interface screens and navigate through temporal context. For example, in response to detecting swipe  630   a , device  600  translates platters  606  and  608 , displays platter  620 , and updates scroll indicator  618   b  ( FIG. 6I ).  FIGS. 6I and 6C  demonstrate that swiping display  602  can be used interchangeably with rotating  610   a  to scroll the user interface (e.g., in either direction, as described herein). 
       FIG. 6J  illustrates exemplary platters  606 ,  608 ,  634 ,  636 ,  638 ,  640 ,  642 ,  644 ,  646 ,  648 ,  650 ,  652 ,  654 , and  656  that can be displayed on display  602 . For example, platter  632  is associated with an activity application and displays a reminder to engage in a type of physical activity for a particular duration to meet an exercise goal; platter  634  is associated with an alarm application and displays the time of an upcoming saved alarm; platter  636  is associated with a breathe reminder application and displays a reminder to breathe/meditate; platter  638  is associated with a navigation application and displays an indication of predicted traffic conditions; platter  640  is associated with a news application and displays a headline; platter  642  is associated with a reminder application and displays a reminder and its designated time; platter  644  is associated with a stocks application and displays a stock, its closing price, and recent stock activity; platter  646  is associated with a photos application and displays a user photo; platter  648  is associated with a photos application and displays a user photo; platter  650  is associated with a wallet application and displays a purchased movie ticket; platter  652  is associated with a sunrise/sunset application and displays the time of today&#39;s sunset; platter  654  is associated with a home application and displays an affordance for activating a stored setting for one or more home devices (e.g., lights, curtains, music, door/window locks, etc.); and platter  656  is associated with a sunrise/sunset application and displays the time of tomorrow&#39;s sunrise. 
     Device  600  can use a variety of selection criteria, alone or in any combination, to select what set(s) of information are surfaced to the user in a platter, as illustrated by  FIG. 6J . In some embodiments, the set of selection criteria includes temporal context of the set of information. For example, a calendar event (e.g., as shown in platter  608 ), weather notification (e.g., as shown in platter  606 ), reminder (e.g., as shown in platter  642 ), alarm, (e.g., as shown in platter  634 ), photo (e.g., a photo taken on a previous date on the current day of the month or year, as shown in platter  646 ), sunset/sunrise time (e.g., as shown in platters  652  and  656 ), or closing stock price (e.g., as shown in platter  644 ) can be selected for display because they relate to a current or upcoming time (e.g., in the current day). 
     In some embodiments, the selection criteria includes temporal context of the set of information and one or more additional selection criteria. In some embodiments, whether a set of information obtained from an application is displayed in a platter is determined based on data obtained from multiple applications. For example, information can be surfaced to the user because it relates to a particular application and a set of selection criteria are met, determined based on data from another application; an activity platter can be selected for display because the displayed reminder relates to the activity application (e.g., based on data related to the user&#39;s daily activity goal) and a set of criteria are met based on data from the calendar application (e.g., a predetermined amount of time until the next scheduled calendar event). In some embodiments, the selection criteria includes proximity to a second device (e.g., device belonging to a contact). 
     In some embodiments, the selection criteria can include time until the next scheduled calendar event. In this example, the temporal context relates to a time of day when device  600  surfaces this set of information to the user. If the user has sufficient time between scheduled events, the device can surface a reminder from the activity application (e.g., platter  632 ) because the user has time for a workout or other activity. In some embodiments, the selection criteria can include a number of calendar events scheduled for the current day. Platter  636  can be displayed because the set of information relates to a different temporal context and the breathe reminder application. In this instance, device  600  can surface a breathe reminder to the user because several consecutive calendar events have been concluded, and thus the user may wish to take a minute to breathe and recover. In some embodiments, the selection criteria can include the application from which the information is obtained. For example, device  600  can select an activity reminder (e.g., as shown in platter  632 ) because an activity goal for the day is still outstanding, or device  600  can select a breathe reminder because the day&#39;s scheduled calendar events have concluded (as described above). These functionalities allow the device to surface sets of information from various applications at times when the user may wish to use these functionalities, rather than at a predetermined time designated by the user or an external data source. 
     In some embodiments, the selection criteria can include location information. For example, platter  650  can be displayed because the set of information (a movie ticket) relates to a temporal context (upcoming showtime during the current day; 7:15 pm in this example) and location (e.g., device  600  is close to the movie theater). Platter  638  can be displayed because the set of information (traffic conditions) relates to a temporal context (a time of day when the user typically begins their commute, or the time of day most common for commuting generally) and location (e.g., device  600  is close to the work, not home, and the predicted traffic is between work and home). Platter  648  can be displayed because it relates to location (e.g., device  600  is near the location where a previous user photo was taken). In some embodiments, device  600  obtains data representing its current location from a location sensor associated with device  600  (e.g., GPS sensor  532  of device  600 , or GPS module  135  of device  100  paired or coupled via wireless communication with device  600 ). In some embodiments, the location information is obtained from another application, such as a calendar application. For example, the device can display a platter with a set of information (e.g., weather conditions) from a weather application pertaining to the location of an upcoming calendar event. If the user is in San Francisco, but has a calendar event or plane ticket to New York later in the day, the device can display a platter with weather information related to New York. 
     In some embodiments, the selection criteria can include one or more previous user inputs. For example, platter  654  can be displayed prior to a time of day when the user has previously used the home application (e.g., at bedtime). Platter  638  can be displayed prior to a time of day when the user has previously started their commute. In this example, the user input can be a movement of the device corresponding to the user traveling home, e.g., one or more inputs received from GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof. 
     In addition to displaying sets of information related to particular temporal contexts of the current day, these context-specific user interfaces can also display sets of information related to the current day, e.g., independent of a specific temporal context, or related to a majority of the current day. These “all-day” events are also accessible by scrolling the user interface. As shown in  FIG. 6K , when platters  606  and  608  are displayed (e.g., the current time view), the user rotates  610   a  in the direction opposite scroll  616   a  (e.g., scroll  658   a ). 
     In response to detecting scroll  658   a , the device  600  displays the screen shown in  FIG. 6L . Platter  606  is translated on-screen, scroll indicator  618   b  is updated, and “all-day” platter  660  is displayed. Platter  660  is associated with a weather application and displays a set of information related to the entire current day (e.g., predicted weather conditions and high and low temperatures forecasted for the current day). 
     Later in the day, display  602  shows platters  620  and  622  ( FIG. 6M ). Current time indicator  604  has been updated in  FIG. 6M  to reflect the current time. Compared to the screen shown in  FIG. 6K , the screen shown in  FIG. 6M  shows different events because the current time is later (e.g., 1:00 as compared to 10:09). Since the sets of information displayed in platters  620  and  622  are now most current at 1:00, these platters are displayed instead of platters  606  and  608 . Thus, different platters can be displayed to the user at different times of day. In some embodiments, platters displaying sets of information related to past times in the current day cease to display on display  602 . In some embodiments, one platter corresponding to the most recent past event is displayed. 
     The user scrolls the user interface by rotating  610   a  via scroll  658   b . In response to detecting scroll  658   b , the device displays the screen shown in  FIG. 6N . As shown in  FIG. 6N , device  600  displays platters  620  and  660 . Thus, the user can access information from “all-day” platters (e.g.,  660 ) at any time in the current day, while event-specific platters (e.g.,  606  or  620 ) can be displayed based on specific temporal contexts within the current day. In summary, scrolling the user interface screen (e.g., by rotating  610   a  and/or swiping) in one direction reveals future event platters related to the current day and/or the next day (see  FIGS. 6B-6I ), and scrolling the user interface screen (e.g., by rotating  610   a  and/or swiping) in the other direction reveals “all-day” event platters related to the current day (see  FIGS. 6K-6N ). 
     In some embodiments, one or more “all-day” event platters can be selected (e.g., by the device) for display based on one or more selection criteria, e.g., as described above. For example, platter  660  can be surfaced to the user because it relates to a location (e.g., all-day weather conditions at the current location of the device) and/or the application from which the set(s) of information are obtained (e.g., showing an all-day weather platter). 
     In some embodiments, in addition to or in place of displaying sets of information obtained from the corresponding application, event and all-day platters can also serve as affordances to launch the corresponding application. In  FIG. 6O , the user contacts displayed platter  606  with tap  662   a . In response to detecting tap  662   a , device  600  ceases to display platter  606  and displays a user interface screen from the corresponding application (in this example, a weather application;  FIG. 6P ). 
     The user can also select displayed complications to launch applications. In  FIG. 6Q , in order to launch a personal assistant application, the user contacts displayed complication  614  with tap  662   b . In response to detecting tap  662   b , device  600  ceases to display complication  614  and displays a user interface screen from the corresponding application ( FIG. 6R ). In some embodiments, complication  614  is “pinned” to the user interface screen such that it remains displayed (and optionally in a fixed position) while the event and/or all-day platters are scrolled (see  FIGS. 6B-6N ). This allows the user to use the complication at any time, regardless of which event platters are shown. In some embodiments, the personal assistant application is launched to reflect a context of a currently running application, or the most recently launched application. 
     The user may wish to edit the application represented by complication  614  and/or other aspects of the user interface, such as colors, density of displayed information, and so forth. Additional descriptions of editing and/or selecting context-specific user interfaces and sub-components thereof may be found in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205, which is incorporated by reference herein in its entirety. 
     In  FIG. 6S , the user accesses an edit mode of device  600  through press  664 , which in some embodiments can be a press having a duration longer than a predetermined duration (e.g., a “long press” input) or a contact having a characteristic intensity above an intensity threshold. In this example, in response to detecting press  664 , device  600  enters a context-specific user interface selection mode and visually distinguishes the user interface screen to indicate the selection mode ( FIG. 6T ). Device  600  alerts to the user that it has entered into the selection mode by displaying smaller representation  666  of the user interface screen, name  668  corresponding to a name of the type of context-specific user interface currently selected, partial view  670  of an adjacent, stored context-specific user interface (which the user could select by swiping to view the full interface and tapping to select it), and edit affordance  672 . In order to edit the user interface, the user contacts edit affordance  672  via tap  674 . 
     In response to detecting tap  674 , the device enters edit mode and visually distinguishes one or more aspects of the user interface for editing ( FIG. 6U ). In this example, complication  614  is selected for editing. Device  600  informs the user that complication  614  is selected for editing by visually distinguishing complication  614  via displaying outline  676   a  around complication  614  and indicator  676   b , which indicates the application represented by the complication (in this example, the personal assistant application). Device  600  also displays scroll indicator  680   a , which informs the user that additional applications can be selected by scrolling and indicates the position of the personal assistant application along the series of displayable application options. Device  600  also displays paging affordance  678 , which indicates that two options for editing different aspects of the user interface can be selected (e.g., by swiping). In this example, the options include the application represented by complication  614  and one or more colors associated with the user interface (e.g., one or more colors of the current time indicator and/or displayed platters). 
     In response to detecting scroll  682  (a rotation of  610   a ), device  600  replaces complication  614  with complication  684 , which represents a remote application ( FIG. 6V ). In addition, indicator  676   b  is updated to indicate the remote application, and scroll indicator  680   b  is updated to reflect the position of the remote application along the series of selectable application options. In some embodiments, in response to detecting one or more additional inputs, device  600  displays a user interface screen based on the display  602  shown in  FIG. 6V  (e.g., a depression of  610   a  followed by a tap on the displayed user interface in selection mode). In some embodiments, device  600  stores the edited user interface in memory (e.g., in memory  518  and/or memory  102  of device  100  paired or coupled via wireless communication with device  600 ). In some embodiments, the edited user interface screen can be subsequently selected in selection mode, e.g., as described in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205 (see, e.g., display  1322  in  FIG. 13 ). 
       FIGS. 7A-7E  show a flow diagram illustrating process  700  for providing context-specific user interfaces. In some embodiments, process  700  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ), or  600  ( FIGS. 6A-6V ). Some operations in process  700  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 7A , at block  702 , the device displays a user interface screen comprising a current time indicator and a first platter at a first position (e.g., on the display). As shown in block  704 , the first platter is associated with a first application and displays a first set of information obtained from the first application (see, e.g., platter  608  in  FIG. 6C , which is associated with a calendar application and displays the time, name, and location of a scheduled calendar event). As shown in block  706 , the first set of information relates to a first temporal context of the current day (e.g., the time of the calendar event). As described above, a “temporal context” can relate to a time attached to a set of information by the user, a time attached to a set of information by an external data source, or a time attached to a set of information by an electronic device of the present disclosure. 
     At block  708 , the device detects a user input. In some embodiments, detecting the user input comprises detecting a rotation of a rotatable input mechanism (e.g., scroll  616   b  in  FIG. 6C ). In some embodiments, detecting the user input comprises detecting a swipe on a touch-sensitive display (e.g., swipe  630   a  in  FIG. 6H ). 
     At block  710 , in response to detecting the user input, the device displays the first platter at a second position different from the first position (cf. the position of platter  608  in  FIGS. 6C and 6D ). In some embodiments, the first platter is displayed at the second position at a larger size (e.g., appearing larger and/or closer to the viewer) than when displayed at the first position (cf. platter  608  in  FIGS. 6C and 6D ). In some embodiments, the first platter displays more information when displayed at the second position than when displayed at the first position (cf. platter  608  in  FIGS. 6C and 6D ). 
     At block  712 , in response to detecting the user input, the device displays a second platter at the first position (e.g., platter  620  in  FIG. 6D ). As shown in block  714 , the second platter is associated with a second application and displays a second set of information obtained from the second application (see, e.g., platter  620  in  FIG. 6D , which is associated with a navigation application and displays the time of predicted traffic conditions). As shown in block  716 , the second set of information relates to a second temporal context of the current day. In some embodiments, the first and the second applications are different. For example, in some embodiments, the first and the second applications are each an independently selected application selected from: weather, calendar, activity, breathe reminder, photos, reminder, and stocks applications. In some embodiments, the first and the second temporal contexts are different. In some embodiments, the first and the second temporal contexts are the same. Displaying sets of information obtained from different applications, throughout temporal contexts in the current day, provides the user with relevant application data (and optionally affordances for launching applications) from multiple applications without necessitating the display of multiple, dedicated application widgets (each dedicated to, and showing information obtained from, a single application). Providing additional control options without cluttering the user interface with additional displayed controls (e.g., dedicated application widgets) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In  FIG. 7B , at block  718 , the device optionally detects a second user input (e.g., after displaying the second platter). In some embodiments, detecting the second user input comprises detecting a rotation of a rotatable input mechanism (e.g., scroll  616   c  in  FIG. 6D ). In some embodiments, detecting the second user input comprises detecting a swipe on a touch-sensitive display (e.g., swipe  630   a  in  FIG. 6H ). 
     At block  720 , in response to detecting the second user input, the device optionally displays the second platter at a position different from the first position on the display (see platter  620  in  FIG. 6E ). As shown in block  722 , in some embodiments, the device optionally ceases to display the first platter (see disappearance of platter  608  from  FIG. 6D  to  FIG. 6E ) before displaying the second platter (e.g., at the second position). 
     At block  724 , in response to detecting the second user input, the device optionally displays a third platter at the first position (see platter  622  in  FIG. 6E ). In some embodiments, as shown in block  726 , the third platter is associated with a third application and displays a third set of information obtained from the third application. The third application is different from the first and the second applications, and the third set of information relates to a third temporal context of the current day. In some embodiments, as shown in block  728 , the third platter is associated with the first application and displays a third set of information obtained from the first application. The first and the third sets of information are different, the third set of information relates to a third temporal context of the current day, and the first and the third temporal contexts are different. This enables the device to display different sets of application information, each of which may be relevant at a different time of day, without requiring the user to launch the application(s) in order to access the multiple sets of information. Performing an operation when a set of conditions (e.g., relevant temporal context and/or particular application) has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  730 , in response to detecting the second user input, the device optionally displays the first platter at a third position different from the first and the second positions on the display (see the positions of platter  620  in  FIGS. 6C, 6D, and 6E ). 
     In  FIG. 7C , at block  732 , the device optionally displays on the display an indicator of position along a series of positions, e.g., in response to detecting the first user input (see indicator  618   b  in  FIG. 6C ). The indicator of position along a series of positions indicates a position of the second platter along a series of displayable platters. 
     At block  734 , in response to detecting the second user input, the device optionally updates the indicator of position to indicate a position of the third platter along the series of displayable platters (cf. scroll indicators  618   a - 618   f  in  FIGS. 6B-6G ). Displaying an updating scroll indicator that indicates a position of a currently selected option along a series of selectable options provides feedback to the user that the received user input (e.g., rotating  610   a ) controls selection of the displayed option while helping the user to navigate through the entire series of options (as well as indicating to the user that additional options are displayable). Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  736 , the device optionally detects a contact (e.g., on the touch-sensitive display) after displaying the second platter. In some embodiments, the contact is at a position on the display different from the positions of the displayed platter(s) and/or complication(s). In some embodiments, the contact is a tap gesture (e.g., tap  628  in  FIG. 6G ). 
     At block  738 , in response to detecting the contact, the device optionally ceases to display the second platter. 
     At block  740 , in response to detecting the contact, the device optionally displays the first platter at the first position (see platter  608  in  FIG. 6H ). 
     At block  742 , the device optionally detects a third user input, e.g., after displaying the second platter. In some embodiments, detecting the third user input comprises detecting a rotation of a rotatable input mechanism (e.g., scroll  616   d  or  616   e  in  FIGS. 6E &amp; 6F ). In some embodiments, detecting the third user input comprises detecting a swipe on a touch-sensitive display (e.g., swipe  630   a  in  FIG. 6H ). 
     In  FIG. 7D , at block  744 , the device optionally displays a fourth platter on the display in response to detecting the third user input. In some embodiments, as shown in block  746 , the fourth platter is associated with a fourth application and displays a fourth set of information obtained from the fourth application, and the fourth application is different from the first and the second applications. In some embodiments, as shown in block  748 , the fourth platter is associated with the first application and displays a fourth set of information obtained from the first application, and the first and the fourth sets of information are different. The fourth set of information relates to a temporal context of a future day (e.g., tomorrow), such as the sets of information shown by platters  624  and  626  in  FIG. 6G . 
     At block  750 , the device optionally detects a user input corresponding to a selection of the first platter. For example, in some embodiments, detecting the user input comprises detecting a contact on the touch-sensitive display at (e.g., on or near) the displayed first platter (see tap  662   a  in  FIG. 6O ). 
     At block  752 , the device optionally launches the first application in response to detecting the user input corresponding to a selection of the first platter. In some embodiments, launching the first application comprises ceasing to display the first user interface screen and displaying a second user interface screen corresponding to the application (see  FIG. 6P ). 
     At block  754 , the device optionally displays an affordance that represents an application (see complication  614  in  FIG. 6Q ). In some embodiments, the affordance is displayed at a position different from the first and the second positions on the display. In some embodiments, the affordance represents an application that is different from the first and the second applications. In some embodiments, the affordance represents the first or the second application. In some embodiments, the affordance comprises a set of information obtained from the application it represents. In some embodiments, the set of information is updated in accordance with data (e.g., updated data) obtained from the application it represents. In some embodiments, the affordance is displayed in the same position on the display before and after updating the set of information. 
     At block  756 , the device optionally detects a user input corresponding to a selection of the affordance (e.g., a tap on or near the displayed affordance, such as tap  662   b  in  FIG. 6Q ). 
     At block  758 , the device optionally launches the application represented by the affordance in response to detecting the user input corresponding to a selection of the affordance. In some embodiments, launching the application comprises ceasing to display the first user interface screen and displaying a second user interface screen corresponding to the application (see  FIG. 6R ). 
     In  FIG. 7E , at block  760 , the device optionally detects a user input corresponding to a request to enter an affordance edit mode of the electronic device, e.g., before launching the application. In some embodiments, the user input is a press having a duration longer than a predetermined duration (e.g., a “long press” input). In some embodiments, the device determines whether the detected press has a duration longer than a predetermined duration and, in accordance with a determination that the detected press has a duration longer than the predetermined duration, enters the affordance edit mode. In some embodiments, the user input is a contact having a characteristic intensity above an intensity threshold. In some embodiments, the device determines whether the detected contact has a characteristic intensity above a predetermined duration and, in accordance with a determination that the detected press has a characteristic intensity above the predetermined duration, enters the affordance edit mode. 
     At block  762 , the device optionally enters an affordance edit mode in response to detecting the user input corresponding to a request to enter an affordance edit mode. In some embodiments, as shown at block  764 , entering the affordance edit mode comprises displaying an edit mode affordance on the touch-sensitive display (e.g., affordance  672  in  FIG. 6T ) and, as shown at block  766 , detecting a user input corresponding to a selection of the edit mode affordance (e.g., tap  674  in  FIG. 6T ). 
     At block  768 , the device optionally visually distinguishes the affordance to indicate the affordance edit mode in response to detecting the user input corresponding to a request to enter an affordance edit mode. For example, the device can display an outline around the affordance, animate an outline around the affordance, animate the affordance (e.g., to flash or expand and contact) change a color of the affordance, and/or display an additional indicator to visually distinguish the affordance (see outline  676   a  and indicator  676   b  in  FIG. 6U ). Visually distinguishing the affordance to indicate edit mode provides improved feedback to the user both that the device has entered a different mode of functionality (for example, tapping the affordance can lead to launch of the corresponding application during a mode other than edit mode but select the affordance for editing during edit mode) and that the distinguished affordance is the aspect of the interface currently selected for editing. Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, as shown at block  770 , visually distinguishing the affordance to indicate the affordance edit mode further comprises displaying an indicator of position along a series of positions, the indicator indicating a first position along the series (e.g., scroll indicator  680   a  in  FIG. 6U ). 
     At block  772 , the device optionally detects a second user input corresponding to a request to change the application represented by the affordance. For example, in some embodiments, detecting the second user input comprises detecting a rotation of a rotatable input mechanism (e.g., scroll  682  received by rotatable input mechanism  610   a  in  FIG. 6U ). 
     At block  774 , the device optionally updates the affordance to represent a different application in response to detecting the second user input corresponding to a request to change the application represented by the affordance (see affordance  784  and indicator  676   b  in  FIG. 6V ). In some embodiments, as shown at block  776 , the device updates the indicator of position to indicate a second position along the series, where the indicator of position along a series of positions indicates a position of a currently selected option for the application represented by the affordance along a series of selectable options for the application represented by the affordance (see scroll indicator  680   b  in  FIG. 6V ). 
     It should be understood that the particular order in which the operations in  FIGS. 7A-7E  have been described is merely exemplary 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. 
     Note that details of the processes described above with respect to process  700  (e.g.,  FIGS. 7A-7E ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  700 . For example, one or more of the steps of process  700  can be combined with one or more of the steps of process  800 , as described below. For brevity, these details are not repeated below. 
       FIGS. 8A-8G  show a flow diagram illustrating process  800  for providing context-specific user interfaces. In some embodiments, process  800  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ), or  600  ( FIGS. 6A-6V ). Some operations in process  800  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 8A , at block  802 , the device displays at a first time a user interface screen comprising a current time indicator, a first platter at a first position (e.g., on the display), and an affordance at a second position (e.g., on the display). The current time indicator reflects the first time of the current day (e.g., indicator  604  in  FIG. 6K ). As shown in block  804 , the first platter is associated with a first application and displays a first set of information obtained from the first application (see, e.g., platter  606  in  FIG. 6K , which is associated with a weather application and displays the time and a description of a predicted change in weather or inclement weather conditions). As shown in block  806 , the first set of information relates to a first temporal context of the current day (e.g., the time of the predicted change in weather or inclement weather conditions). As shown in block  808 , the affordance represents an application (e.g., affordance  614  in  FIG. 6K , which represents a personal assistant application). In some embodiments, the affordance comprises a set of information obtained from the application it represents. In some embodiments, the set of information is updated in accordance with data (e.g., updated data) obtained from the application it represents. In some embodiments, the affordance is displayed in the same position on the display before and after updating the set of information. 
     At block  810 , the device detects a first user input corresponding to a request to scroll the first user interface screen. In some embodiments, the first user input comprises a rotation of a rotatable input mechanism (e.g., scroll  658   a  received at rotatable input mechanism  610   a  shown in  FIG. 6K ). In some embodiments, the first user input comprises a swipe on a touch-sensitive display. 
     At block  812 , in response to detecting the first user input, the device maintains display of the affordance at the second position (cf. affordance  614  in  FIG. 6K  and  FIG. 6L ). 
     In  FIG. 8B , at block  814 , in response to detecting the first user input, the device displays a second platter at the first position. In some embodiments, as shown in block  816 , the second platter is associated with a second application (e.g., platter  660  associated with a weather application as shown in  FIG. 6L ) and displays a second set of information obtained from the second application (e.g., weather conditions and/or high and low temperatures forecasted for the current day, as shown in platter  660  in  FIG. 6L ). In some embodiments, the first and the second applications are the same. In some embodiments, the first and the second applications are different. In some embodiments, as shown in block  818 , the second set of information relates to the current day (e.g., to a temporal context of the current day broader than the first temporal context). 
     At block  820 , the device displays at a second time (e.g., a different time of day than the first time), a second user interface screen comprising the current time indicator, a third platter at the first position on the display (e.g.,  620  in  FIG. 6M ), and the affordance at the second position on the display (e.g.,  614  in  FIG. 6M ). As shown in block  822 , the third platter is associated with a third application (e.g., a navigation application, as shown in  FIG. 6M ) and displays a third set of information obtained from the third application (e.g., time of a predicted change in traffic, such as traffic along the user&#39;s route home). As shown in block  824 , the third set of information relates to a third temporal context of the current day. As shown in block  826 , the current time indicator reflects the second time of the current day (e.g., indicator  604  in  FIG. 6M ). In some embodiments, the first and the third applications are the same. In some embodiments, the first and the third applications are different. Displaying sets of information obtained from different applications, some of which change throughout the day (e.g., based on temporal context) and some of which are constant throughout the day, provides the user with relevant application data (and optionally affordances for launching applications) from a variety of applications without necessitating the display of multiple, dedicated application widgets (each dedicated to, and showing information obtained from, a single application). Providing additional control options without cluttering the user interface with additional displayed controls (e.g., dedicated application widgets) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  828 , the device detects a second user input corresponding to a request to scroll the second user interface screen. In some embodiments, the second user input comprises a rotation of a rotatable input mechanism (e.g., scroll  658   b  received at rotatable input mechanism  610   a  shown in  FIG. 6M ). In some embodiments, the second user input comprises a swipe on a touch-sensitive display. 
     In  FIG. 8C , at block  830 , in response to detecting the second user input, the device maintains display of the affordance at the second position (cf. affordance  614  in  FIG. 6M  and  FIG. 6N ). 
     At block  832 , in response to detecting the second user input, the device displays the second platter at the first position (e.g., platter  660  in  FIG. 6N ). 
     At block  834 , the device optionally detects a third user input corresponding to a request to scroll the second user interface screen in a second scroll direction different from the first scroll direction. In some embodiments, the third user input comprises a rotation of a rotatable input mechanism (e.g., scroll  616   a  received at rotatable input mechanism  610   a  shown in  FIG. 6B , which is in an opposite direction as compared to scroll  658   a ). In some embodiments, the third user input comprises a swipe on a touch-sensitive display (e.g., in an opposite swipe direction). 
     At block  836 , the device optionally maintains display of the affordance at the second position in response to detecting the third user input. 
     At block  838 , the device optionally displays a fourth platter at the first position on the display in response to detecting the third user input. As shown in block  840 , the fourth platter is associated with a fourth application and displays a fourth set of information obtained from the fourth application. In some embodiments, the first and the fourth applications are the same. In some embodiments, the first and the fourth applications are different. As shown in block  842 , the fourth set of information relates to a fourth temporal context of the current day, and the fourth temporal context is different from the third temporal context. In some embodiments, the fourth temporal context is later than the third temporal context in the current day. 
     In  FIG. 8D , at block  844 , the device optionally displays on the display an indicator of position along a series of positions in response to detecting the second user input. The indicator of position along a series of positions indicates a position of the second platter along a series of displayable platters (e.g., scroll indicator  618   b  in  FIG. 6N ). 
     At block  846 , the device optionally updates the indicator of position to indicate a position of the fourth platter along the series of displayable platters in response to detecting the third user input. Displaying an updating scroll indicator that indicates a position of a currently displayed platter along a series of displayable platters provides feedback to the user that the received user input (e.g., scroll  616   a ) controls selection of the displayed platter(s) while helping the user to navigate through the entire series of platter options (as well as indicating to the user that additional platters are displayable). Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  848 , the device optionally detects a fourth user input corresponding to a request to scroll the second user interface screen in the second scroll direction (e.g., scrolls  616   d  and  616   e  in  FIGS. 6E and 6F ). 
     At block  850 , the device optionally maintains display of the affordance at the second position in response to detecting the fourth user input. 
     At block  852 , the device optionally displays a fifth platter at the first position on the display in response to detecting the fourth user input (e.g., platter  624  in  FIG. 6F ). As shown in block  854 , the fifth platter is associated with a fifth application and displays a fifth set of information obtained from the fifth application. In some embodiments, the first and the fifth applications are the same. In some embodiments, the first and the fifth applications are different. As shown in block  856 , the fifth set of information relates to a temporal context of the next day (e.g., a number of calendar events, as shown in platter  624  in  FIG. 6G , or tomorrow&#39;s predicted weather, as shown in platter  626  in  FIG. 6G ). 
     In  FIG. 8E , at block  858 , the device optionally detects a fifth user input. In some embodiments, the fifth user input comprises a contact on the touch-sensitive display (e.g., tap  628  in  FIG. 6G ). In some embodiments, the fifth user input comprises a rotation of a rotatable input mechanism. 
     At block  860 , the device optionally maintains display of the affordance at the second position in response to detecting the fifth user input. 
     At block  862 , the device optionally ceases to display the fourth platter in response to detecting the fifth user input. 
     At block  864 , the device optionally displays the third platter at the first position in response to detecting the fifth user input. 
     At block  866 , the first and the third sets of information are selected for display based at least in part on a set of one or more selection criteria. For example, as described in reference to  FIG. 6J , the set of one or more selection criteria can comprise a temporal context of the current day (e.g., the time of a calendar event shown in platter  606  or the showtime associated with a movie ticket shown in platter  650  in  FIG. 6J ). In some embodiments, the set of one or more selection criteria can comprise a temporal context of the current day and one or more selection criteria selected from: location (e.g., the photo represented in platter  648  in  FIG. 6J ), the application from which the first or the third set of information is obtained (e.g., surfacing traffic conditions from a navigation application to the user at the time of the user&#39;s commute home, as shown in platter  638  in  FIG. 6J ), a number of calendar events scheduled for the current day (e.g., surfacing a breathe reminder to the user after consecutive calendar events, as shown in platter  636  in  FIG. 6J ), time until the next scheduled calendar event (e.g., surfacing an activity reminder to the user when the user has time for a workout before the next scheduled calendar event, as shown in platter  632  in  FIG. 6J ), and one or more previous user inputs (e.g., surfacing a platter associated with a home application at a time when the user has previously launched the home application, as shown in platter  654  in  FIG. 6J ). Optionally, as shown in block  868 , if the set of one or more selection criteria comprises proximity to the current location of the electronic device (e.g., the photo shown in platter  648 , or the reminder to leave work when the device detects that it is near the user&#39;s designated workplace shown in platter  638  in  FIG. 6J ), the device obtains its current location from a location sensor associated with the electronic device (e.g., GPS sensor  532  of device  600 , or GPS module  135  of device  100  paired or coupled via wireless communication with device  600 ). Using, via the device, the set of one or more selection criteria to automatically generate and display a platter provides information to the user that is relevant to the current time (e.g., providing the user with a workout or breathe reminder when their schedule allows, as determined in accordance with data from the calendar application) without requiring a user input (e.g., to set such a reminder in advance). Performing operations when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. Using selection criteria further allows the device to display different platters at different times of day from a variety of applications without necessitating the display of multiple, dedicated application widgets (each dedicated to, and showing information obtained from, a single application). Providing additional control options without cluttering the user interface with additional displayed controls (e.g., dedicated application widgets) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  870 , the device optionally selects the second set of information for display based at least in part on a second set of one or more selection criteria. For example, the second set of selection criteria can include one or more selection criteria selected from: location and the application from which the second set of information is obtained. In some embodiments, the second set of one or more selection criteria does not comprise a temporal context of the current day. In some embodiments, the second set of information relates to a majority of time within the current day (e.g., the weather conditions and high/low temperatures shown in platter  660  in  FIGS. 6L and 6N ). In some embodiments, the second set of information relates to a temporal context of the current day that is broader than the first and the third temporal contexts (e.g., the weather conditions and high/low temperatures shown in platter  660  in  FIG. 6L , as compared to the weather alert shown in platter  606  in  FIG. 6K ). Optionally, as shown in block  872 , if the second set of one or more selection criteria comprises proximity to the current location of the electronic device, the device obtains its current location from a location sensor associated with the electronic device (e.g., GPS sensor  532  of device  600 , or GPS module  135  of device  100  paired or coupled via wireless communication with device  600 ). 
     In  FIG. 8F , at block  874 , the device optionally detects a user input corresponding to a selection of the second platter. For example, detecting the user input can comprise detecting a contact at (e.g., on or near) the displayed second platter, such as tap  662   a  on platter  606  in  FIG. 6O . 
     At block  876 , the device optionally launches the second application in response to detecting the user input corresponding to a selection of the second platter. In some embodiments, launching the second application comprises ceasing to display the first or second user interface screen and displaying a third user interface screen corresponding to the second application (see  FIG. 6P ). 
     At block  878 , the device optionally detects a user input corresponding to a selection of the affordance. For example, detecting the user input can comprise detecting a contact at (e.g., on or near) the displayed affordance, such as tap  662   b  on complication  614  in  FIG. 6Q . 
     At block  880 , the device optionally launches the second application in response to detecting the user input corresponding to a selection of the affordance. In some embodiments, launching the application comprises ceasing to display the first or second user interface screen and displaying a fourth user interface screen corresponding to the application (see  FIG. 6R ). 
     At block  882 , the device optionally detects a user input corresponding to a request to enter an affordance edit mode. In some embodiments, the user input is a press having a duration longer than a predetermined duration (e.g., a “long press” input). In some embodiments, the device determines whether the detected press has a duration longer than a predetermined duration and, in accordance with a determination that the detected press has a duration longer than the predetermined duration, enters the affordance edit mode. In some embodiments, the user input is a contact having a characteristic intensity above an intensity threshold. In some embodiments, the device determines whether the detected contact has a characteristic intensity above a predetermined duration and, in accordance with a determination that the detected press has a characteristic intensity above the predetermined duration, enters the affordance edit mode. 
     At block  884 , the device optionally enters an affordance edit mode in response to detecting the user input corresponding to a request to enter an affordance edit mode. In some embodiments, as shown at block  886 , entering the affordance edit mode comprises displaying an edit mode affordance on the touch-sensitive display (e.g., affordance  672  in  FIG. 6T ) and, as shown at block  888 , detecting a user input corresponding to a selection of the edit mode affordance (e.g., tap  674  in  FIG. 6T ). 
     In  FIG. 8G , at block  890 , the device optionally visually distinguishes the affordance to indicate the affordance edit mode in response to detecting the user input corresponding to a request to enter an affordance edit mode. For example, the device can display an outline around the affordance, animate an outline around the affordance, animate the affordance (e.g., to flash or expand and contact) change a color of the affordance, and/or display an additional indicator to visually distinguish the affordance (see outline  676   a  and indicator  676   b  in  FIG. 6U ). Visually distinguishing the affordance to indicate edit mode provides improved feedback to the user both that the device has entered a different mode of functionality (for example, tapping the affordance can lead to launch of the corresponding application under normal functioning but select the affordance for editing during edit mode) and that the distinguished affordance is the aspect of the interface currently selected for editing. Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, as shown at block  892 , visually distinguishing the affordance to indicate the affordance edit mode further comprises displaying an indicator of position along a series of positions, the indicator indicating a first position along the series (e.g., scroll indicator  680   a  in  FIG. 6U ). In some embodiments, as shown at block  894 , the device updates the indicator of position to indicate a position of a currently selected option for the application represented by the affordance along a series of selectable options for the application represented by the affordance (see scroll indicator  680   b  in  FIG. 6V ). 
     At block  896 , the device optionally detects a second user input corresponding to a request to change the application represented by the affordance. For example, in some embodiments, detecting the second user input comprises detecting a rotation of a rotatable input mechanism (e.g., scroll  682  received by rotatable input mechanism  610   a  in  FIG. 6U ). 
     At block  898 , the device optionally updates the affordance to represent a different application in response to detecting the second user input corresponding to a request to change the application represented by the affordance (see affordance  784  and indicator  676   b  in  FIG. 6V ). 
     Note that details of the processes described above with respect to process  800  (e.g.,  FIGS. 8A-8G ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  800 . For example, one or more of the steps of process  800  can be combined with one or more of the steps of process  700 , as described above. For brevity, these details are not repeated below. 
       FIGS. 9A-9L  show exemplary context-specific user interfaces that may be operated on device  900 . Device  900  may be device  100 ,  300 , or  500  in some embodiments. The electronic device has a display  902  (e.g.,  504 ). In some embodiments, display  902  is a touch-sensitive display. In some embodiments, device  900  includes rotatable input mechanism  910  (e.g.,  506 ) and/or input mechanism or button (e.g.,  508 ). 
     In  FIG. 9A , device  900  displays a context-specific user interface on display  902 . This exemplary context-specific user interface includes current time indicator  904  (e.g., a digital clock). Indicator  904  can optionally include a variety of features or aspects that are independently editable or configurable by the user. Also included is complication  908 , which is associated with a calendar application and displays a set of information from the calendar application (e.g., day of the week and the current date). 
     The user interface screen illustrated in  FIG. 9A  also includes a non-textual, graphical depiction  906  of a set of information obtained from an application. In this example, depiction  906  depicts a set of information obtained from a weather application: weather conditions (e.g., rain) related to a first temporal context of the current day. For example, the temporal context can be the time of a predicted change in weather conditions or time of predicted inclement weather conditions. Non-textual, graphical depictions can include without limitation emojis, symbols, and/or cartoons. In some embodiments, a non-textual, graphical depiction is displayed as a wallpaper or background on the user interface screen. 
     To view additional graphical depictions of application information, the user rotates rotatable input mechanism  910  (e.g., with scroll  914   a ). In response to detecting scroll  914   a , the device displays scroll indicator  912   a , which indicates the position of depiction  906  along a series of displayable graphical depictions. 
     In response to detecting scroll  914   a , the device displays the screen shown in  FIG. 9B . On this screen, the device displays a second non-textual, graphical depiction  914  of a set of information obtained from a different application. In this example, depiction  914  depicts a set of information obtained from a navigation application: a reminder to leave for home (e.g., based on estimated driving time from work to home) related to a second temporal context of the current day. For example, the second temporal context can be the time of day associated with the user&#39;s commute home (e.g., a predicted time of day, or a time of day associated with one or more previous user inputs indicative of commuting home). Scroll indicator  912   b  is also updated to indicate the position of depiction  914  along the series of displayable graphical depictions. Text  916  is also displayed and provides a textual description related to depiction  914 . 
     The user can also swipe the touch-sensitive display to scroll the user interface screen. For example, in response to detecting swipe  914   b , device  900  displays the user interface screen shown in  FIG. 9C . This screen includes a third non-textual, graphical depiction  918  of a set of information obtained from a different application. In this example, depiction  918  depicts a set of information obtained from a calendar application: a calendar event related to a third temporal context of the current day. For example, the third temporal context can be the time of the scheduled calendar event (e.g., a date for coffee). Scroll indicator  912   c  is also updated to indicate the position of depiction  918  along the series of displayable graphical depictions. Text  920  is also displayed and provides a textual description related to depiction  918 . 
     In some embodiments, device  900  can receive data representing text content from a depicted set of information and generate the depiction to depict the text content based on the received data. For example, device  900  can receive data related to the text content of the calendar event (e.g., “meet Ben for coffee”) and generate depiction  918  using a cartoon coffee cup based on, or in accordance with, the received data. This increases the user interactability of the device, thereby improving the man-machine interface. 
     In some embodiments, depictions  906 ,  914 , and  918  depict sets of information related to increasingly later temporal contexts of the current day (e.g., moving forward in time). In order to scroll backwards in time, the user rotates  910  in the opposite direction (e.g., scroll  914   c ). In response to detecting scroll  914   c , device  900  displays the screen shown in  FIG. 9D . This screen includes depiction  914 , and scroll indicator  912   b  has been updated to reflect the corresponding position of depiction  914  along the series. 
     Any of depictions  906 ,  914 , and  918  can also serve as affordances to launch the corresponding application. As shown in  FIG. 9E , the user can contact displayed depiction  906  (e.g., via tap  922 ). In response to detecting tap  922 , device  900  displays a user interface screen from the weather application ( FIG. 9F ). This allows the user to view additional information from the weather application. 
     Displayed complications can also serve as affordances to launch the corresponding application. As shown in  FIG. 9G , the user can contact displayed complication  908  (e.g., via tap  924 ). In response to detecting tap  924 , device  900  displays a user interface screen from the calendar application ( FIG. 9H ). This allows the user to view additional information from the calendar application, such as the time(s) of one or more upcoming calendar event(s). 
     The user may wish to change the application associated with a displayed complication (or change the set of information from the application displayed by the complication). The user presses display  902  with press  926  ( FIG. 9I ). In some embodiments, press  926  is a press having a duration longer than a predetermined duration (e.g., a “long press” input), or a press having a characteristic intensity above a predetermined intensity threshold. 
     In response to detecting press  926 , device  900  visually distinguishes the user interface screen to indicate edit mode ( FIG. 9J ). Device  900  alerts to the user that it has entered into the selection mode by displaying smaller representation  930  of the user interface screen, name  932  corresponding to a name of the type of context-specific user interface currently selected, partial view  934  of an adjacent, stored context-specific user interface (which the user could select by swiping to view the full interface and tapping to select it), and edit affordance  936 . In order to edit the user interface, the user contacts edit affordance  936  via tap  938 . 
     In response to detecting tap  938 , the device enters edit mode and visually distinguishes one or more aspects of the user interface for editing ( FIG. 9K ). In this example, complication  908  is selected for editing. Device  900  informs the user that complication  908  is selected for editing by visually distinguishing complication  908  via displaying outline  940  around complication  908  and indicator  942 , which indicates the application represented by the complication (in this example, indicating the calendar application). Device  900  also displays scroll indicator  944   a , which informs the user that additional applications can be selected by scrolling and indicates the position of the calendar application along the series of displayable application options. Device  900  also displays paging affordance  946 , which indicates that two options for editing different aspects of the user interface can be selected (e.g., by swiping). In this example, the options include the application represented by complication  908  and one or more colors associated with the user interface (e.g., one or more colors of the current time indicator and/or displayed depictions). 
     In response to detecting scroll  948  (a rotation of  910 ), device  900  replaces complication  908  with complication  950 , which represents a stopwatch application ( FIG. 9L ). In addition, indicator  952  is updated to indicate the stopwatch application, and scroll indicator  944   b  is updated to reflect the position of the stopwatch application along the series of displayable application options. In some embodiments, in response to detecting one or more additional inputs, device  900  displays a user interface screen based on the display  902  shown in  FIG. 9L  (e.g., a depression of  910  followed by a tap on the displayed user interface in selection mode). In some embodiments, device  900  stores the edited user interface in memory (e.g., in memory  518  and/or memory  102  of device  100  paired or coupled via wireless communication with device  900 ). In some embodiments, the edited user interface screen can be subsequently selected in selection mode, e.g., as described in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205 (see, e.g., display  1322  in  FIG. 13 ). 
       FIGS. 10A-10C  show a flow diagram illustrating process  1000  for providing context-specific user interfaces. In some embodiments, process  1000  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ), or  900  ( FIGS. 9A-9L ). Some operations in process  1000  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 10A , at block  1002 , the device displays a user interface screen comprising a current time indicator (e.g.,  904  in  FIG. 9A ) and a first non-textual, graphical depiction (e.g.,  906  in  FIG. 9A ). As shown at block  1004 , the first non-textual, graphical depiction depicts a first set of information obtained from a first application, e.g., a calendar event, user photo, change in weather conditions, breathe or activity reminder, and so forth (additional sets of information are described supra). As shown at block  1006 , the first set of information relates to a first temporal context of the current day. For example, depiction  906  depicts forecasted weather conditions obtained from a weather application related to an upcoming time of the current day. 
     At block  1008 , the device detects a user input. In some embodiments, the user input comprises a rotation of a rotatable input mechanism (e.g., scroll  914   a  received at rotatable input mechanism  910  shown in  FIG. 9A ). In some embodiments, the first user input comprises a swipe on a touch-sensitive display (e.g., swipe  914   b  on display  902  shown in  FIG. 9B ). 
     At block  1010 , in response to detecting the user input, the device ceases to display the first non-textual, graphical depiction. 
     At block  1012 , in response to detecting the user input, the device displays a second non-textual, graphical depiction (see depiction  914  in  FIG. 9B ). As shown at block  1014 , the second non-textual, graphical depiction depicts a second set of information obtained from a second application. As shown at block  1016 , the second set of information relates to a second temporal context of the current day. For example, depiction  914  depicts forecasted traffic conditions obtained from a navigation application related to the user&#39;s upcoming commute home. In some embodiments, the first and the second applications are the same. In some embodiments, the first and the second applications are different. In some embodiments, the first and the second non-textual, graphical depictions are displayed as wallpapers or backgrounds on the user interface screen. In some embodiments, the first and/or second set(s) of information are selected by the device for display based on one or more selection criteria, as described supra. Displaying sets of information obtained from different applications, but relating to time(s) in the current day, provides the user with relevant application data (and optionally affordances for launching applications) from a variety of applications without necessitating the display of multiple, dedicated application widgets (each dedicated to, and showing information obtained from, a single application). Providing additional control options without cluttering the user interface with additional displayed controls (e.g., dedicated application widgets) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In  FIG. 10B , at block  1018 , the device optionally receives data representing text content from the second set of information in response to detecting the user input (e.g., before displaying the second non-textual, graphical depiction). For example, text content can comprise one or more keywords. 
     At block  1020 , in response to detecting the user input, the device optionally generates the second non-textual, graphical depiction to depict the text content based on the received data (e.g., a cup of coffee to depict a “coffee” keyword, as shown by depiction  918  in  FIG. 9C ). Thus, the device automatically generates a graphical depiction of text content related to application data (e.g., a calendar event) and surfaces the depiction to the user at a relevant time of day (e.g., based on one or more selection criteria, as described supra) without requiring the user to select the application data (e.g., select a keyword from a calendar event) or when to display it. Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1022 , in response to detecting the user input, the device optionally displays an indicator of position along a series of positions (e.g., scroll indicators  912   a - 912   c  in  FIGS. 9A-9D ). The indicator of position along a series of positions indicates a position of the second non-textual, graphical depiction along a series of displayable non-textual, graphical depictions. Displaying an updating scroll indicator that indicates a position of a currently displayed depiction along a series of displayable depictions provides feedback to the user that the received user input (e.g., scroll  914   a  in  FIG. 9A , scroll  914   c  in  FIG. 9C , or swipe  914   b  in  FIG. 9B ) controls display of depictions that include application information while helping the user to navigate through the entire series of depictions (as well as indicating to the user that additional depictions are displayable). Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1024 , detecting the user input comprises detecting a swipe (e.g., on a touch-sensitive display) in a first swipe direction. See swipe  914   b  on display  902  shown in  FIG. 9B . 
     At block  1026 , the device optionally detects a second swipe in a second direction different from the first swipe direction. 
     At block  1028 , in response to detecting the second swipe, the device optionally ceases to display the second non-textual, graphical depiction. 
     At block  1030 , in response to detecting the second swipe, the device optionally displays the first non-textual, graphical depiction on the display. 
     At block  1032 , detecting the user input comprises detecting a rotation of a rotatable input mechanism in a first direction of rotation (e.g., scroll  914   a  received at rotatable input mechanism  910  shown in  FIG. 9A ). 
     At block  1034 , the device optionally detects a second rotation in a second direction different from the first direction of rotation. 
     At block  1036 , in response to detecting the second rotation, the device optionally ceases to display the second non-textual, graphical depiction. 
     At block  1038 , in response to detecting the second rotation, the device optionally displays the first non-textual, graphical depiction on the display. 
     In  FIG. 10C , at block  1040 , the device optionally displays an affordance representing a calendar application (e.g., complication  908  in  FIG. 9G ). In some embodiments, as shown at block  1042 , the affordance indicates the current date. 
     At block  1044 , the device optionally detects a user input corresponding to a selection of the affordance (e.g., tap  924  on complication  908  in  FIG. 9G ). 
     At block  1046 , in response to detecting the user input corresponding to a selection of the affordance, the device launches the calendar application (see  FIG. 9H ). In some embodiments, launching the calendar application comprises ceasing to display the user interface screen and displaying a second user interface screen corresponding to the calendar application. 
     Note that details of the processes described above with respect to process  1000  (e.g.,  FIGS. 10A-10C ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  1000 . For example, one or more of the steps of process  1000  can be combined with one or more of the steps of processes  700  or  800 , as described above. For brevity, these details are not repeated below. 
     Turning now to  FIG. 11A , users may wish to generate new images for display on a portable multifunction device, e.g., to provide the user different experiences as the display is viewed multiple times a day. This keeps the user interested and engaged with the electronic device. Tying the generation of these new images to the time of day provides improved techniques for timekeeping and further enhances the timekeeping functionality of the device. 
       FIGS. 11A-11N  show exemplary context-specific user interfaces that may be operated on device  1100 . Device  1100  may be device  100 ,  300 , or  500  in some embodiments. The electronic device has a display  1102  (e.g.,  504 ). In some embodiments, display  1102  is a touch-sensitive display. In some embodiments, device  1100  includes a rotatable input mechanism  1120   a  (e.g.,  506 ) and/or input mechanism or button  1120   b  (e.g.,  508 ). 
       FIG. 11A  (top) illustrates an exemplary context-specific user interface displayed on display  1102  of device  1100 . This user interface screen includes current time indicator  1104  (in this example, an analog clock with an hour hand, minute hand, and optional seconds hand). Also displayed in association with  1104  are three complications  1106 ,  1108 , and  1110 . These three complications are each associated with an application (an alarm, weather, and calendar application, respectively). In some embodiments, one or more of these complications displays a set of information obtained from the corresponding application. For example, complication  1108  displays a current temperature obtained from the weather application, and complication  1110  displays the time of an upcoming calendar event and a text descriptor. In some embodiments, complication  1110  occupies more space on display  1102  and optionally displays more information from the corresponding application (e.g., an increased number of characters or increased image size), as compared to complications  1106  and  1108 . This provides the user with multiple levels of detail for displaying application information. Complication  1106  graphically represents the alarm application without displaying a set of information from the alarm application (textual representations could also be used). 
     Also displayed on this user interface screen is background  1112   a . In some embodiments, background  1112   a  is displayed as a wallpaper on display  1102 . In some embodiments, background  1112   a  is displayed as the clock face of analog clock  1104 . 
     Background  1112   a  displays a kaleidoscope-style composite image  1118  ( FIG. 11A , bottom) created from image  1114  ( FIG. 11A , middle). Device  1100  creates composite image  1118  by selecting portion  1116  of image  1114  and reflecting portion  1116  across a plurality of axes of reflection. For example, device  1100  can display  12  facets of portion  1116  mirrored 6 times, or any other combination of number of axes of reflection and number of facets to generate a suitable image. 
       FIG. 11A  shows composite image  1118  displayed as background  1112   a  on display  1102  at 10:09. Later, when the user activates the display (e.g., as described infra) at 12:25, multiple aspects of display  1102  are updated ( FIG. 11B ). Current time indicator  1104  is updated to reflect the current time. In some embodiments, the set(s) of information displayed by one or more complication(s) are updated, e.g., in accordance with data from the corresponding application. In this example, complication  1108  is updated to display the current temperature, and complication  1110  is updated to display the time of an upcoming calendar event and a text descriptor. Complication  1106  is not updated. 
     Background  1112   b  is also updated. Device  1100  creates composite image  1124  by selection portion  1122  of image  1114  and reflecting portion  1122  across a plurality of axes of reflection (in some embodiments, the same axes of reflection used to generate composite image  1118 ). Thus, device  1100  can select different portions of the same image at different times of day, thereby increasing the variety of its displayed background. 
     In some embodiments, the selection of the image portion is based on time of day. This concept is illustrated in  FIG. 11C . Like  FIG. 11A , display  1102  in  FIG. 11C  (top) shows a user interface screen with current time indicator  1104  and complications  1106 ,  1108 , and  1110 . Analog clock  1104  indicates that the current time is the same time as shown in  FIG. 11A , e.g., on a different day. Complication  1108  has been updated to indicate the current temperature, and complication  1110  has been updated to indicate the time of an upcoming calendar event and a text descriptor. Complication  1106  is not updated. 
     Background  1112   c  in  FIG. 11C  is the same as background  1112   a  in  FIG. 11A . For example, background  1112   c  is created by device  1100  by selecting portion  1116  of image  1114  and reflecting portion  1116  across the same plurality of axes of reflection. Thus, the selection and/or reflection of an image portion can be determined based on time of day. 
     In some embodiments, device  1100  can select a portion (e.g., portion  1116 ) of an image (e.g., image  1114 ) based on a set of one or more criteria. In some embodiments, device  1100  can associate a score (e.g., an “interestingness score”) with a plurality of portions of an image (e.g.,  1114 ). For example, device  1100  can divide an image into a plurality of portions (e.g., a grid) and associate a score with each portion of the plurality. In some embodiments, the score is based on one or more of the following scoring criteria: luminance, average luminance, derivative of luminance, and chroma value. In some embodiments, device  1100  selects a portion based on its score (e.g., it selects a portion having a score above a predetermined threshold). This is advantageous, e.g., because some image portions may be incompatible with reflection (e.g., an image portion having a single color or black/white hue would not be amendable to reflection and composite image generation). 
     In some embodiments, device  1100  can apply a selection path through the image to select image portions based on time of day. For example, the selection path can be a deterministic path guiding portion selection that repeats at a regular interval, such as every 12 or every 24 hours. Thus, a user can perceive the time of day based on which portion of the image is selected and displayed as a kaleidoscope. In some embodiments, the selection path comprises two or more image portions having a selection score above a predetermined threshold (e.g., as described above). In some embodiments, device  1100  detects a user input (e.g., a rotation of a rotatable input mechanism), and in response to detecting the user input, the device selects a second image portion along the selection path for reflection and composite image generation. In some embodiments, the user can select an image portion, e.g., by providing a user input corresponding to a selection of an image portion. 
     Device  1100  can apply a variety of axes of reflection to an image portion, thereby generating kaleidoscope-type composite images in a variety of patterns. Exemplary patterns based on portion  1116  of image  1114  are shown in  FIG. 11D . In some embodiments, the axes of reflection create a kaleidoscope pattern, e.g., by applying multiple axes of reflection to create a set of reflected facets. In some embodiments, the axes of reflection create a radial pattern, e.g., by taking a slice of the image and rotating the slice in a circle to create a plurality of axes of reflection. In some embodiments, the axes of reflection create a tessellated pattern, e.g., by tiling the background with a series of reflected image portions. Various types of tessellations are known and are well known in the work of the artist M. C. Escher; see, e.g., repeated triangles to generate a sphere (e.g., a Schwarz triangle), or tiling in a hyperbolic plane (e.g., a Poincaré disk). In some embodiments, the axes of reflection create a pattern based on the Fibonacci sequence, e.g., by repeating reflected image portions in numbers of spirals according to the Fibonacci sequence (such as the number of seed spirals on a sunflower). 
     This context-specific user interface allows the user to launch an application by selecting the corresponding complication. For example, the user contacts complication  1108  (e.g., via tap  1120 ) in  FIG. 11E . In response to detecting tap  1120 , device  1100  updates display  1102  to show a user interface from the corresponding weather application ( FIG. 11F ). 
     The user may wish to view the original image, e.g., to identify the portion selected for composite image generation. The user contacts background  1112   a  (e.g., via tap  1122 ) in  FIG. 11G . In response to detecting tap  1122 , the device displays image  1114 , e.g., as background  1124 . 
     The user may wish to edit the application represented by complication  1108  and/or other aspects of the user interface, such as colors (e.g., a color of a seconds hand of  1104 ), density of displayed information (e.g., hour markings of  1104 , or lack thereof), and so forth. Additional descriptions of editing and/or selecting context-specific user interfaces and sub-components thereof may be found in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205, which is incorporated by reference herein in its entirety. 
     In  FIG. 11I , the user accesses an edit mode of device  1100  through press  1130 , which in some embodiments can be a press having a duration longer than a predetermined duration (e.g., a “long press” input) or a contact having a characteristic intensity above an intensity threshold. In this example, in response to detecting press  1130 , device  1100  enters a context-specific user interface selection mode and visually distinguishes the user interface screen to indicate the selection mode ( FIG. 11J ). Device  1100  alerts to the user that it has entered into the selection mode by displaying smaller representation  1132  of the user interface screen, name  1136  corresponding to a name of the type of context-specific user interface currently selected, partial view  1138  of an adjacent, stored context-specific user interface (which the user could select by swiping to view the full interface and tapping to select it), and edit affordance  1134 . In order to edit the user interface, the user contacts edit affordance  1134  via tap  1140 . 
     In response to detecting tap  1140 , the device enters edit mode and visually distinguishes one or more aspects of the user interface for editing ( FIG. 11K ). In this example, background  1140  is selected for editing (e.g., selecting a photo from which the portion is selected). Device  1100  informs the user that background  1140  is selected for editing by visually distinguishing background  1140  via displaying an outline around background  1140  and indicator  1142 , which indicates that the source photo for background  1140  is editable. Device  1100  also displays scroll indicator  1146 , which informs the user that additional photos can be selected by scrolling and indicates the position of the photo along the series of displayable photo-based backgrounds. Device  1100  also displays paging affordance  1144 , which indicates that three options for editing different aspects of the user interface can be selected (e.g., by swiping). In this example, the options include the photo from which background  1140  is selected, the application associated with various complications, and the type of pattern used to generate the composite image. 
     To edit the photo, the user can rotate  1120   a . To edit a different aspect of the interface, the user swipes display  1102  via swipe  1148 . In response to detecting swipe  1148 , the device indicates complication  1108  for editing ( FIG. 11L ). Device  1100  informs the user that complication  1108  is selected for editing by visually distinguishing complication  1108  via displaying outline  1150  around complication  1108  and indicator  1152 , which indicates the application represented by the complication (in this example, indicating the weather application). Device  1100  also displays scroll indicator  1154 , which informs the user that additional applications can be selected by scrolling and indicates the position of the weather application along the series of displayable application options. Further in response to detecting swipe  1148 , device  1100  updates paging affordance  1144  to reflect the position of complication editing in the series of editable aspects. 
     To select the pattern used to generate the composite image, the user swipes display  1102  via swipe  1156 . In response to detecting swipe  1156 , the device displays the screen shown in  FIG. 11M . In  FIG. 11M , the composite image  1158  on which the background is based is visually indicated via displaying outline  1158   a  around composite image  1158  and indicator  1158   b , which indicates that the pattern (e.g., of axes of reflection) used to generate the composite image  1158  for background  1140  is editable. Device  1100  also displays scroll indicator  1160   a , which informs the user that patterns can be selected by scrolling and indicates the position of the pattern along the series of selectable patterns. Further in response to detecting swipe  1156 , device  1100  updates paging affordance  1144  to reflect the position of pattern editing in the series of editable aspects. 
     To change the pattern, the user rotates  1120   a  via scroll  1162 . In response to detecting scroll  1162 , device  1100  generates composite image  1166  using the same image portion as  1158 , but applying a different pattern of axes of reflection ( FIG. 11N ). Indicator  1158   b  is also updated to reflect the pattern of axes of reflection. Scroll indicator  1160   b  is also updated to indicate the position of the radial pattern along the series of selectable pattern options. In some embodiments, the user can then exit edit mode and display the edited user interface screen. In some embodiments, upon exiting edit mode, the device saves the edited user interface screen in memory, e.g., such that it can be subsequently selected in selection mode, e.g., as described in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205 (see, e.g., display  1322  in  FIG. 13 ). 
     Turning now to  FIG. 12 , it may be advantageous to allow the user to use an electronic device (e.g., a first device) to configure a context-specific user interface for a different portable multifunction device (e.g., a second device). In some embodiments, the first device has a larger display than the second device, thereby making it easier for the user to see and/or provide touch gestures on the first device. The user may wish to configure a user interface for the second device while operating the first device without switching over to the second device. 
       FIG. 12  illustrates an exemplary first electronic device  1200  and an exemplary second electronic device  1210 . In some embodiments, device  1200  may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). For purposes of illustration, first device  1200  is a personal electronic device, similar to portable multifunction device  100  as depicted in  FIG. 4A , with a touch-sensitive display  1202 . In some embodiments, second device  1210  may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). For purposes of illustration, external device  1210  is a personal electronic device, similar to device  500  as depicted in  FIG. 5A , with a touch-sensitive display  1212 , a rotatable input mechanism, and a button. 
     As depicted in  FIG. 12 , device  1200  is capable of receiving information over a wireless network. In some embodiments, device  1200  is coupled via wireless communication to device  1210 .  FIG. 12  also indicates that device  1200  is capable of operating in a paired relationship with external device  1210  to exchange data between the two devices. In a paired relationship, device  1200  and device  1210  are registered with one another and can perform two-way wireless communication. In some embodiments, wireless communication, for purposes of a paired relationship, occurs over a peer-to-peer wireless communication protocol such as Bluetooth and/or Bluetooth Low Energy (BTLE). In some embodiments, the wireless communication uses more than one wireless communication protocol. For example, WiFi may be used in addition to BTLE. In these embodiments, an initial communication between two devices may occur over a lower powered protocol, such as BTLE, even if the protocol yields a slower data transfer speed. Subsequent communications may occur over a secondary network that is relatively faster, such as WiFi. Additional exemplary techniques related to initiating and operating in a paired relationship are described in the following co-pending applications: International Patent Application Serial No. PCT/US2015/023699, titled “Companion Application for Activity Cooperation,” filed Mar. 31, 2015 published as WIPO Publication No. WO/2015/0183403; U.S. patent application Ser. No. 14/474,466, titled “Predefined Wireless Pairing,” filed Sep. 2, 2014, published as US PG Pub. No. 20150350865; International Patent Application Serial No. PCT/US2015/047507, titled “Reduced-size Configuration Interface,” filed Aug. 28, 2015 published as WIPO Publication No. WO/2016/036603; and U.S. Provisional Patent Application titled “Reduced-size Configuration Interface,” filed Mar. 8, 2015, naming Lawrence Y. Yang et al. as inventors. Referring to  FIG. 12 , a user may wish to configure a context specific user interface using device for display on device  1210  using device  1200 . 
       FIG. 13  illustrates exemplary electronic device  1300  and an exemplary electronic device  1320 . In some embodiments, device  1300  may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). For purposes of illustration, first device  1300  is a personal electronic device, similar to portable multifunction device  100  as depicted in  FIG. 4A , with a touch-sensitive display  1302 . In some embodiments, second device  1320  may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). For purposes of illustration, external device  1320  is a personal electronic device, similar to device  500  as depicted in  FIG. 5A , with a touch-sensitive display  1322  and a rotatable input mechanism  1324 . Devices  1300  and  1320  are coupled via wireless communication. In some embodiments, devices  1300  and  1320  are in a paired relationship, e.g., as described in reference to  FIG. 12 . 
     Device  1320  has access to a library of context-specific user interfaces for display on display  1322 . For example, the library can be stored in memory of device  1320 , stored in memory of device  1300  and accessible to device  1320 , and/or stored at an external server accessible to devices  1300  and  1320 . In some embodiments, context-specific user interfaces are stored in the library as unique or complete assets. In some embodiments, the library stores context-specific user interfaces as configurations that are rendered for display by device  1320  (e.g., by rendering a set of graphical assets stored in memory according to the configuration, which specifies the particular graphical asset(s) used and their arrangement within the user interface). 
       FIG. 13  also illustrates a user interface, at device  1300 , for selecting, reordering, and/or editing context-specific user interfaces from the stored library for display on device  1320 . The user interface screen shown on display  1302  includes depiction  1304  of device  1320 , which optionally includes a depiction of device name, size, and/or other device features. In some embodiments, depiction  1304  serves as an affordance that, when contacted by the user, displays additional information and/or functionality related to device  1320 , such as options for pairing or de-pairing device  1320  with another electronic device. The user interface screen shown on display  1302  includes complications bar  1306 . In some embodiments, complications bar  1306  allows the user to view a list of complications that can be configured for display as part of a context-specific user interface from the library, as well as optional affordances for selecting and/or editing particular complications. In some embodiments, the user scrolls on the depicted user interface screen (e.g., with a horizontal swipe) to view particular complication options. Screen  1302  further includes affordance  1308  for viewing one or more user interfaces from the library. In some embodiments, the user touches affordance  1308 , and in response device  1300  displays the user interface illustrated on screen  1302 . 
     Also shown on the user interface screen of display  1302  are preview images  1310 ,  1312 , and  1314 . Preview images  1310 ,  1312 , and  1314  represent context-specific user interfaces from the library for display on device  1320 . As represented by preview images  1310  and  1312 , both corresponding user interfaces include a clock. In addition, the user interface represented by  1312  includes a complication, as described herein. In some embodiments, the preview image(s) are displayed with an associated text element indicating the type of watch face for the corresponding context-specific user interface (e.g., “sun” for the user interface represented by  1310 , “utility” for the user interface represented by  1312 , etc.). The user interface screens shown on displays  1302  and  1322  indicate to the user what user interfaces are stored in the library and the order or sequence of the user interfaces within the library. 
     In some embodiments, the preview image includes a representation of one or more complications of the user interface. For example, preview image  1312  includes representation  1316 , which represents a complication of the user interface represented by  1312 . In this example, representation  1316  represents a complication that displays an affordance representing a weather application. As discussed above, complications can obtain data and display information obtained from an associated application (optionally, the information is updated in accordance with updates to the data). In some embodiments, device  1300  obtains “live” data from the weather application and displays information updated according to updates to the data in representation  1316  (e.g., the sun depicted in  1316  indicates current weather conditions, representing live data obtained from the weather application). Advantageously, this allows the user to visualize how the user interface looks when displayed on device  1320  at the current time. In other embodiments, device  1300  displays a “placeholder” representation of application data. For example, the sun depicted in  1316  can be an icon or affordance that represents to the user the content of the live data that would be displayed in the complication. For example, the placeholder may be installed as part of the app and/or designated as part of a software development kit used to develop the application. Advantageously, this allows the user to understand the function of the complication within the user interface but does not require processor resources and/or communication bandwidth to obtain live data to generate the preview image. 
     Preview image  1314  is shown in partial view. This alerts the user to the fact that additional preview images representing the rest of the stored library are viewable in this interface, e.g., by scrolling. In some embodiments, the user swipes the display at one or more of preview images  1310 ,  1312 , and  1314  (e.g., a horizontal swipe), and in response to detecting the swipe, device  1300  scrolls the displayed preview images to reveal one or more additional preview images representing user interfaces from the library. 
     In some embodiments, information in one or more preview images shown on display  1302  and/or  1322  is updated live, e.g., while the user is in face selection mode of device  1320  or viewing preview images at display  1302 . For example, in some embodiments, a representation of a clock on one or more of  1310 ,  1312 ,  1314 ,  1330 ,  1332 , and/or  1334  is rendered live, e.g., such that the preview image displays current time. In some embodiments, a representation of one or more complications on one or more of  1310 ,  1312 ,  1314 ,  1330 ,  1332 , and/or  1334  is rendered live, e.g., such that the preview image displays current complication data (e.g., information from an application updated in accordance with updates to application data). In some embodiments, a representation of one or more complications on a currently centered preview image (e.g., displayed in complete view, such as  1310  or  1330 ) is rendered live, while a representation of one or more complications on a currently non-centered preview image (e.g., displayed in partial view, such as  1312 ,  1314 ,  1332  or  1334 ) is not rendered live (e.g., it displays placeholder data, or data obtained at a previous refresh, such as the last time the represented user interface was displayed, or the last time the preview image was centered on the display). In some embodiments, a representation of one or more complications on a currently centered preview image (e.g., displayed in complete view, such as  1310  or  1330 ) and representation(s) on preview images immediately adjacent to the currently centered preview image are rendered live (e.g.,  1312 ,  1314 ,  1332  or  1334 ), while a representation of one or more complications on a preview image that is not currently centered and not adjacent to a currently centered preview image is not rendered live (e.g., it displays placeholder data, or data obtained at a previous refresh, such as the last time the represented user interface was displayed, or the last time the preview image was centered on the display). In some embodiments, a representation that is not rendered live may be rendered using data updated at a longer interval than a representation that is rendered live. In some embodiments, one or more elements or user interface objects represented in a preview image other than those representing a clock or a complication may be shown as a static element (e.g., not rendered according to updated data). 
       FIG. 14A  illustrates exemplary electronic device  1400 . In some embodiments, device  1400  may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). For purposes of illustration, device  1400  is a personal electronic device, similar to portable multifunction device  100  as depicted in  FIG. 4A , with a touch-sensitive display  1402 . In some embodiments, device  1400  is in a paired relationship (e.g., as described in reference to  FIG. 12 ) with a second device (e.g.,  1210  or  1320 ), which may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). 
     Display  1402  includes preview image  1404  of a context-specific user interface, similar to those described in  FIGS. 11A-11N , for display on the second device. Also displayed are a number of editable aspects of the context-specific user interface. In this example, the user can edit the image used to create a composite image for the background, the applications and/or sets of information displayed by one or more complications, and the type of pattern (e.g., of axes of reflection) used to generate the composite image. Representations of selectable options for these editable aspects are also displayed. For example, representations  1406 ,  1408 , and  1410  represent images that can be selected for composite image generation. In some embodiments, one or more of the images are system-designated or curated images. In some embodiments, one or more of the images are user-designated images, e.g., photos taken by the user. Representations  1412 ,  1414 , and  1416  represent types of pattern (e.g., of axes of reflection) that can be used to generate a composite image-based background (e.g., as described supra). 
       FIGS. 14B &amp; 14C  illustrate selection of an option for pattern. A kaleidoscope pattern is currently selected for generation of a composite image displayed as background  1462   a  on display  1452  of device  1450  in  FIG. 14B . Display  1452  also shows complications  1456 ,  1458 , and  1460 , and current time indicator  1454 . The screen on display  1402  of device  1400  also informs the user of this currently selected option using representation  1404 , which represents the user interface currently selected for display by device  1450 . 
     In  FIG. 14B , the user selects representation  1414 , which represents a radial pattern (e.g., of axes of reflection). In this example, the user contacts representation  1414  displayed on display  1402  of device  1400  via tap  1420 . In some embodiments, representation  1414  further comprises representations of one or more of complications  1456 ,  1458 , and  1460 , and current time indicator  1454 . 
     In response to detecting tap  1420 , device  1400  updates representation  1404  with a representation of a composite image generated using a radial pattern of reflection ( FIG. 14C ). In some embodiments, representation  1404  represents the same interface displayed by  1450 . In some embodiments, representation  1404  represents an interface comprising a placeholder composite-image based background that represents the radial pattern to the user. This informs the user at device  1400  how the selected option will change the user interface screen displayed by device  1450 . In some embodiments, representation  1404  further comprises representations of one or more of complications  1456 ,  1458 , and  1460  (e.g., using live application data or placeholder data), and current time indicator  1454 . 
     Further in response to detecting tap  1420  at device  1400 , device  1450  updates background  1462   b  to generate a composite image using the radial pattern (e.g., of axes of reflection;  FIG. 14C ). Compared to background  1462   a , background  1462   b  is based on the same image portion, but reflected across a different plurality of axes of reflection (e.g., in a radial pattern). For example, device  1400  can send instructions to device  1450  to generate a composite image using the radial pattern in response to detecting tap  1420 . 
       FIGS. 14D &amp; 14E  illustrate selection of an image for the background. A photo of a bridge is currently selected for generation of a composite image displayed as background  1462   a  on display  1452  of device  1450  in  FIG. 14D . Display  1452  also shows complications  1456 ,  1458 , and  1460 , and current time indicator  1454 . The screen on display  1402  of device  1400  also informs the user of this currently selected option using representation  1404 , which represents the user interface currently selected for display by device  1450 . 
     In  FIG. 14D , the user selects representation  1408 , which represents a different image of a beach. In this example, the user contacts representation  1408  displayed on display  1402  of device  1400  via tap  1430 . 
     In response to detecting tap  1420 , device  1400  updates representation  1404  with a representation of a composite image generated using a radial pattern of reflection ( FIG. 14E ). In some embodiments, representation  1404  represents the same interface displayed by  1450 . In some embodiments, representation  1404  represents an interface comprising a placeholder composite-image based background that represents the radial pattern to the user. This informs the user at device  1400  how the selected option will change the user interface screen displayed by device  1450 . In some embodiments, representation  1404  further comprises representations of one or more of complications  1456 ,  1458 , and  1460  (e.g., using live application data or placeholder data), and current time indicator  1454 . 
     Further in response to detecting tap  1430  at device  1400 , device  1450  updates background  1462   c  to generate a composite image using the beach photo ( FIG. 14E ). Compared to background  1462   a , background  1462   c  uses the same plurality of axes of reflection (e.g., in a kaleidoscope pattern), but applied to a different image portion (e.g., a portion of the beach photo instead of the bridge photo. For example, device  1400  can send instructions to device  1450  to generate a composite image using the beach photo in response to detecting tap  1430 . 
       FIGS. 15A-15E  show a flow diagram illustrating process  1500  for providing context-specific user interfaces. In some embodiments, steps of process  1500  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ),  1100  ( FIGS. 11A-11N ),  1400  ( FIGS. 14A-14E ), or  1450  ( FIGS. 14A-14E ). Some operations in process  1500  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 15A , at block  1502 , the device displays a user interface screen comprising a current time indicator (e.g., indicator  1104  in  FIG. 11A ) and a background. In some embodiments, the current time indicator comprises an analog or digital clock. 
     At block  1504 , the device detects a change in time. 
     At block  1506 , in response to detecting the change in time, the device selects a first portion of an image (e.g., portion  1116  of image  1114  in  FIG. 11A ). In some embodiments, the first portion is less than the entire image. In some embodiments, the image is a system-designated or curated image. In some embodiments, the image is a user-designated image, such as a user photo (e.g., stored on the device, or on a device in wireless communication with the device). In some embodiments, the device automatically selects the first portion of the image (e.g., in the absence of a user input corresponding to a selection of the image portion). Automatically selecting the portion of the image using the device enhances the variety of backgrounds that can be displayed by the device without requiring the user to select a portion each time the image changes (e.g., numerous backgrounds can be displayed during a given day without the user having to select each time the background changes). Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1508 , in response to detecting the change in time, the device reflects the first portion across a first plurality of axes of reflection to generate a first plurality of reflected portions. In some embodiments, the first plurality of axes of reflection is based on a pattern selected from kaleidoscope, radial reflection, Fibonacci sequence, and tessellation (see  FIG. 11D ). 
     At block  1510 , in response to detecting the change in time, the device replaces the background with a first composite image comprising the first plurality of reflected portions (e.g., background  1118  in  FIG. 11A ). 
     At block  1512 , the device detects a second change in time. 
     At block  1514 , in response to detecting the second change in time, the device selects a second portion of the image (e.g., portion  1122  of image  1114  in  FIG. 11B ). In some embodiments, the second portion is less than the entire image. In some embodiments, the second portion is different from the first portion. In some embodiments, the image is a system-designated or curated image. In some embodiments, the image is a user-designated image, such as a user photo (e.g., stored on the device, or on a device in wireless communication with the device). In some embodiments, the device automatically selects the second portion of the image (e.g., in the absence of a user input corresponding to a selection of the image portion). Automatically selecting the portion of the image using the device enhances the variety of backgrounds that can be displayed by the device without requiring the user to select a portion each time the image changes (e.g., numerous backgrounds can be displayed during a given day without the user having to select each time the background changes). Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1516 , in response to detecting the second change in time, the device reflects the second portion across a second plurality of axes of reflection to generate a second plurality of reflected portions. In some embodiments, the first plurality and the second plurality of axes of reflection are the same. In some embodiments, the second plurality of axes of reflection is based on a pattern selected from kaleidoscope, radial reflection, Fibonacci sequence, and tessellation (see  FIG. 11D ). 
     At block  1518 , in response to detecting the second change in time, the device replaces the background with a second composite image comprising the second plurality of reflected portions (e.g., background  1124  in  FIG. 11B ). 
     In  FIG. 15B , at block  1520 , the device optionally creates a data file encoding the second composite image. This allows the device to create and store new data files encoding images without requiring multiple user inputs, e.g., to select an image, select axes of reflection, and reflecting the image portions. Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1522 , the device optionally stores the data file in memory. In some embodiments, the data file is stored in memory of the device (e.g., device  1320  in  FIG. 13 ). In some embodiments, the data file is stored in memory of a device in wireless communication with the device (e.g., device  1300  in  FIG. 13 ). 
     At block  1524 , the device optionally selects the first portion of the image based on time of day when the first change of time is detected, and the device optionally selects the second portion of the image based on time of day when the second change of time is detected. In some embodiments, as shown in block  1526 , the device applies a selection path through the image (e.g., a deterministic path that selects image portions based on time of day) to select the second portion of the image based on time of day when the second change in time is detected. In some embodiments, as shown in block  1528 , the selection path comprises a predetermined path of portions through an image that repeats at a regular interval (e.g., 12 or 24 hours). Thus, the device displays an image-based background that indicates the time of day (e.g., since the same portion is selected at the same time of day, or since the same portion is selected twice a day such as at 10:00 am and 10:00 pm), thereby providing additional feedback to the user indicative of the time of day. Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1530 , the device optionally detects a third change in time. In some embodiments, the third change in time is detected at the same time of day as the second change in time but on a different day. 
     At block  1532 , the device optionally displays the second composite image in response to detecting the third change in time (e.g., background  1118  in  FIG. 11C ). 
     At block  1534 , in response to detecting the second change in time, the device optionally updates the current time indicator to reflect current time when the second change in time is detected (e.g., indicator  1112   b  in  FIG. 11B ). 
     In some embodiments, the device is coupled via wireless communication to a second electronic device with a display, one or more processors, and memory. In some embodiments, the second electronic device is a personal electronic device, similar to portable multifunction device  100  as depicted in  FIG. 4A , with a touch-sensitive display  1402 . In some embodiments, the second electronic device is in a paired relationship (e.g., as described in reference to  FIG. 12 ) with the device, which may be one or more of devices  100  ( FIG. 1A ),  300  ( FIG. 3 ), and/or  500  ( FIG. 5A ). 
     In  FIG. 15C , at block  1536 , the second electronic device optionally displays a second user interface screen with a first preview image that represents the first image and a second preview image that represents a second image (see, e.g., representations  1406  and  1408  on display  1402  in  FIG. 14D ). In some embodiments, this occurs after the first device replaces the first composite image with the second composite image. 
     At block  1538 , the second electronic device optionally detects a user input corresponding to a selection of the second preview image. In some embodiments, detecting the user input corresponding to the selection of the second preview image comprises detecting a contact on the touch-sensitive display of the second electronic device at (e.g., on or near) the displayed second preview image (e.g., tap  1430  in  FIG. 14D ). In some embodiments, the second image is a user photo stored in the memory of the second electronic device. In some embodiments, detecting the user input corresponding to a selection of the second preview image comprises displaying a third user interface screen comprising a plurality of preview images (e.g., a user interface screen of image management module  144 ). In some embodiments, the plurality of preview images represents a plurality of user photos. In some embodiments, the plurality of preview images comprises the second preview image. 
     At block  1540 , in response to detecting the user input corresponding to a selection of the second preview image, the first or second electronic device optionally selects a portion of the second image. 
     At block  1542 , in response to detecting the user input corresponding to a selection of the second preview image, the first or second electronic device optionally reflects the portion of the second image across a plurality of axes of reflection to generate a third plurality of reflected portions. In some embodiments, the plurality of axes of reflection is the same as the second plurality of axes of reflection. In some embodiments, the plurality of axes of reflection is different from the second plurality of axes of reflection. 
     At block  1544 , in response to detecting the user input corresponding to a selection of the second preview image, the first device optionally replaces the second composite image with a third composite image comprising the third plurality of reflected portions (see background  1462   c  on display  1452  in  FIG. 14E ). In some embodiments, in response to detecting the user input corresponding to a selection of the second preview image, the second electronic device sends data to the first device comprising instructions to replace the second composite image with a third composite image comprising the third plurality of reflected portions. 
     At block  1546 , the second electronic device optionally displays (e.g., as part of the second user interface screen) a preview image representing the first user interface screen on the first electronic device (e.g., representation  1404  in  FIG. 14D ). In some embodiments, the preview image comprises a representation of the second composite image. 
     In  FIG. 15D , at block  1548 , the second electronic device optionally updates the preview image by replacing the representation of the second composite image with a representation of the third composite image (cf. representation  1404  in  FIG. 14D  and  FIG. 14E ) in response to detecting the user input corresponding to a selection of the second preview image. 
     At block  1550 , the second electronic device optionally displays (e.g., as part of the second user interface screen) an affordance representing a pattern of axes of reflection (e.g., representations  1412 ,  1414 , and  1416  on display  1402  in  FIG. 14B ). 
     At block  1552 , the second electronic device optionally detects a user input corresponding to a selection of the affordance representing the pattern of axes of reflection (e.g., tap  1420  in  FIG. 14B ). 
     At block  1554 , in response to detecting the user input corresponding to a selection of the affordance, the first or second electronic device optionally reflects the portion of the second image across a second plurality of axes of reflection to generate a fourth plurality of reflected portions. In some embodiments, the fourth plurality of reflected portions is different from the third plurality of reflected portions. 
     At block  1556 , in response to detecting the user input corresponding to a selection of the affordance, the first device replaces the third composite image with a fourth composite image comprising the fourth plurality of reflected portions (e.g., background  1462   b  in  FIG. 14C ). In some embodiments, the second electronic device optionally updates the preview image by replacing the representation of the second composite image with a representation of the fourth composite image (cf. representation  1404  in  FIG. 14B  and  FIG. 14C ) in response to detecting the user input corresponding to a selection of the affordance. In some embodiments, in response to detecting the user input corresponding to a selection of the affordance, the second electronic device sends data to the first device comprising instructions to replace the third composite image with a fourth composite image comprising the fourth plurality of reflected portions. 
     At block  1558 , the device optionally displays an affordance that represents an application (e.g., complication  1108  in  FIG. 11E ). As shown in block  1560 , in some embodiments, the affordance comprises a set of information obtained from the application it represents. 
     In  FIG. 15E , at block  1562 , the device optionally detects a user input corresponding to a selection of the affordance (e.g., tap  1120  in  FIG. 11E ). 
     At block  1564 , the device optionally launches the application represented by the affordance in response to detecting the user input corresponding to a selection of the affordance (see  FIG. 11F ). In some embodiments, launching the application represented by the affordance comprises ceasing to display the first user interface screen and displaying a third user interface screen corresponding to the application represented by the affordance. 
     At block  1566 , the device optionally receives data from the application represented by the affordance. 
     At block  1568 , the device optionally updates the set of information displayed by the affordance in accordance with the received data (see complication  1108  in  FIGS. 11A-11C , or complication  1110  in  FIGS. 11A-11C ). In some embodiments, the affordance is displayed in the same position on the display before and after updating the set of information. Thus, the affordance is able to display updated information from an application without requiring the user to launch the application to view the updated information. Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1570 , the device optionally detects a contact (e.g., on the touch sensitive display; see tap  1122  in  FIG. 11G ). In some embodiments, the contact is at the displayed second composite image. 
     At block  1572 , the device optionally displays the image (e.g., by replacing the second composite image with the image; see image  1124  in  FIG. 11H ). 
     Note that details of the processes described above with respect to process  1500  (e.g.,  FIGS. 15A-15E ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  1500 . For example, one or more of the steps of process  1500  can be combined with one or more of the steps of process  1600 , as described below. For brevity, these details are not repeated below. 
       FIGS. 16A-16D  show a flow diagram illustrating process  1600  for providing context-specific user interfaces. In some embodiments, process  1600  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ), or  1100  ( FIGS. 11A-11N ). Some operations in process  1600  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 16A , at block  1602 , the device optionally displays a user interface screen comprising a current time indicator (e.g.,  1104  in  FIG. 11A ) and a first composite image (e.g., similar to  1158  in  FIG. 11M ). The image is created by the electronic device (e.g., automatically) by selecting a first portion of an image (block  1604 ), reflecting the first portion across a first plurality of axes of reflection to generate a first plurality of reflected portions (block  1606 ), and displaying the first plurality of reflected portions (block  1608 ). 
     At block  1610 , the device detects a user input corresponding to a request to edit the first composite image. 
     At block  1612 , in response to detecting the user input, the device ceases to display the first composite image. 
     At block  1614 , in response to detecting the user input, the device displays a second composite image (e.g., similar to  1166  in  FIG. 11N ). The image is created by the electronic device (e.g., automatically) by selecting a second portion of the image (block  1616 ), reflecting the second portion across a second plurality of axes of reflection to generate a second plurality of reflected portions (block  1618 ), and displaying the second plurality of reflected portions (block  1620 ). In some embodiments, the first and the second plurality of axes of reflection are different (e.g., based on different patterns). Automatically selecting the portion of the image using the device enhances the variety of backgrounds that can be displayed by the device without requiring the user to select a portion each time the image changes. Performing an operation when a set of conditions has been met without requiring further user input enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In  FIG. 16B , at block  1622 , the device optionally detects a user input corresponding to a request to enter a composite image edit mode of the electronic device (e.g., press  1130  in  FIG. 11I ). In some embodiments, the user input is a press having a duration longer than a predetermined duration (e.g., a “long press” input). In some embodiments, the device determines whether the detected press has a duration longer than a predetermined duration and, in accordance with a determination that the detected press has a duration longer than the predetermined duration, enters the affordance edit mode. In some embodiments, the user input is a contact having a characteristic intensity above an intensity threshold. In some embodiments, the device determines whether the detected contact has a characteristic intensity above a predetermined duration and, in accordance with a determination that the detected press has a characteristic intensity above the predetermined duration, enters the affordance edit mode. 
     At block  1624 , the device optionally enters a composite image edit mode in response to detecting the user input corresponding to a request to enter composite image edit mode. In some embodiments, as shown at block  1626 , entering the composite image edit mode comprises displaying an edit mode affordance on the touch-sensitive display (e.g., affordance  1134  in  FIG. 11J ) and, as shown at block  1628 , detecting a user input corresponding to a selection of the edit mode affordance (e.g., tap  1140  in  FIG. 11J ). 
     At block  1630 , the device optionally visually distinguishes the composite image to indicate the composite image edit mode in response to detecting the user input corresponding to a request to enter composite image edit mode. For example, the device can display an outline around the affordance, animate an outline around the affordance, animate the affordance (e.g., to flash or expand and contact) change a color of the affordance, and/or display an additional indicator to visually distinguish the affordance (see outline  1140  in  FIG. 11K ). Visually distinguishing the composite image to indicate edit mode provides improved feedback to the user both that the device has entered a different mode of functionality (for example, tapping the composite image can lead to display of the original image during a mode other than edit mode but select the composite image for editing during edit mode) and that the distinguished composite image is the aspect of the interface currently selected for editing. Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. In some embodiments, as shown at block  1632 , visually distinguishing the composite image to indicate the composite image edit mode further comprises displaying an indicator of position along a series of positions, the indicator indicating a first position along the series (e.g., scroll indicator  1160   a  in  FIG. 11M ). In some embodiments, as shown at block  1634 , the device updates the indicator of position to indicate a second position along the series, where the indicator of position along a series of positions indicates a position of a currently selected option for the composite image pattern along a series of selectable options for the composite image (see scroll indicator  1160   b  in  FIG. 11N ). Displaying an updating scroll indicator that indicates a position of a currently displayed composite image pattern along a series of selectable patterns provides feedback to the user that the received user input (e.g., scroll  1162  in  FIG. 11M ) controls selection of the composite image generation pattern while helping the user to navigate through the entire series of patterns (as well as indicating to the user that additional patterns are selectable). Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1636 , the device optionally detects a user input corresponding to a request to select an image (e.g., after visually distinguishing the displayed composite image to indicate an image selection mode). For example, in some embodiments, detecting the user input corresponding to a request to select an image comprises detecting a swipe on the display (e.g., swipe  1148  or  1156  in  FIGS. 11K &amp; 11L ). 
     In  FIG. 16C , at block  1638 , the device optionally ceases to display the second plurality of reflected portions in response to detecting the user input corresponding to a request to select an image. 
     At block  1640 , the device optionally selects a first portion of a second image different from the first image (e.g., automatically by the device) in response to detecting the user input corresponding to a request to select an image. 
     At block  1642 , the device optionally reflects the first portion of the second image across a plurality of axes of reflection to generate a third plurality of reflected portions in response to detecting the user input corresponding to a request to select an image. 
     At block  1644 , the device optionally displays a third composite image comprising the third plurality of reflected portions in response to detecting the user input corresponding to a request to select an image (e.g., background  1166  in  FIG. 11N ). 
     At block  1646 , the device optionally displays an affordance that represents an application (e.g., complication  1108  in  FIG. 11E ). As shown in block  1648 , in some embodiments, the affordance comprises a set of information obtained from the application it represents. 
     At block  1650 , the device optionally detects a user input corresponding to a selection of the affordance (e.g., tap  1120  in  FIG. 11E ). 
     In  FIG. 16D , at block  1652 , the device optionally launches the application represented by the affordance. In some embodiments, launching the application comprises ceasing to display the first user interface screen and displaying a user interface screen corresponding to the application (see  FIG. 11F ). 
     At block  1654 , the device optionally receives data from the application represented by the affordance. 
     At block  1656 , the device optionally updates the set of information displayed by the affordance in accordance with the received data (cf. complication  1108  in  FIGS. 11A-11C ). In some embodiments, the affordance is displayed in the same position on the display before and after updating the set of information. 
     At block  1658 , the device detects a swipe, e.g., after visually distinguishing the displayed composite image to indicate the composite image edit mode (e.g., swipe  1148  in  FIG. 11K ). 
     At block  1660 , the device optionally visually distinguishes the displayed affordance to indicate an affordance edit mode. For example, the device can display an outline around the affordance, animate an outline around the affordance, animate the affordance (e.g., to flash or expand and contact) change a color of the affordance, and/or display an additional indicator to visually distinguish the affordance (see outline  1150  and indicator  1154  in  FIG. 11L ). Visually distinguishing the affordance to indicate edit mode provides improved feedback to the user both that the device has entered a different mode of functionality (for example, tapping the affordance can lead to launching the application during a mode other than edit mode but select the affordance for editing during edit mode) and that the distinguished affordance is the aspect of the interface currently selected for editing. Providing improved feedback enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     At block  1662 , the device optionally detects a user input corresponding to a request to edit the affordance (e.g., scroll  682  in  FIG. 6U ). 
     At block  1664 , the device optionally updates the affordance to represent a second application in response to detecting the user input corresponding to a request to edit the affordance (e.g., complication  684  in  FIG. 6V ). In some embodiments, the affordance comprises a second set of information obtained from the second application. In some embodiments, the second set of information is updated in accordance with data from the second application. In some embodiments, the first and the second applications are different (e.g., personal assistant vs. remote application in  FIGS. 6U-6V ). 
     At block  1666 , the device optionally updates the affordance to comprise a second set of information obtained from the application in response to detecting the user input corresponding to a request to edit the affordance. In some embodiments, the second set of information is updated in accordance with data from the application. In some embodiments, the first and the second sets of information are different. Thus, the user can edit the set of application information that is displayed from multiple options (e.g., multiple time zones from a world clock application, or multiple stock prices from a stocks application). 
     Note that details of the processes described above with respect to process  1600  (e.g.,  FIGS. 16A-16D ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  1600 . For example, one or more of the steps of process  1600  can be combined with one or more of the steps of process  1500 , as described above. For brevity, these details are not repeated below. 
     In any of the embodiments described herein, the device (e.g.,  500 ,  600 ,  900 ,  1100 ,  1210 ,  1320 , and/or  1450 ) can be a portable or reduced-size multifunction device (e.g., a smart watch electronic device) with one or more attachment mechanisms.  FIGS. 17A &amp; 17B  show exemplary device  1700 . Device  1700  may be device  100 ,  300 ,  500 ,  600 ,  900 ,  1100 ,  1210 ,  1320 , or  1450  in some embodiments. The electronic device has a display  1702  (e.g.,  504 ). In some embodiments, display  1702  is a touch-sensitive display. In some embodiments, device  1700  includes a rotatable input mechanism and/or input mechanism or button. 
       FIGS. 17A &amp; 17B  illustrate that device  1700  can detect a user movement of the device and, in response to detecting the user movement, display a user interface screen (e.g., described herein). In some embodiments, the user movement can be a raising and/or rotation of the user&#39;s wrist, or other movement indicative of the user raising the display into viewing position. These movements could be detected, for example, by using an accelerometer (e.g.,  534 ), a gyroscope (e.g.,  536 ), a motion sensor (e.g.,  538 ), and/or a combination thereof. In any of the context-dependent faces described herein, a movement of the device may be a user input that activates the display. 
     In  FIG. 17A , the display of device  1700  is powered off. In  FIG. 17B , in response to detecting a raising and/or rotation of the user&#39;s wrist, device  1700  powers on the display and displays a user interface screen. For any of the user interface screens described above, the display can be powered off prior to displaying the user interface screen, and the device can power on the display and display the user interface screen in response to detecting the a user movement of the device. 
       FIG. 18  shows a flow diagram illustrating process  1800  for displaying context-specific user interfaces. In some embodiments, process  1800  can be performed at an electronic device with a touch-sensitive display, one or more processors, and memory, such as device  100  ( FIG. 1A ),  300  ( FIG. 3 ),  500  ( FIGS. 5A-5H ),  600  ( FIGS. 6A-6V ),  900  ( FIGS. 9A-9L ),  1100  ( FIGS. 11A-11N ),  1450  ( FIGS. 14B-14E ), or  1900  ( FIGS. 19A-19F ). Some operations in process  1800  can be combined, the order of some operations may be changed, and some operations can be omitted. 
     In  FIG. 18 , at block  1802 , the device powers off the display (e.g., display  1702  in  FIG. 17A ). 
     At block  1804 , device  1700  detects a user movement of the device (e.g., raising and/or rotation of the wrist; cf.  FIGS. 17A &amp; 17B ). 
     At block  1806 , the device powers on the display in response to detecting the user movement of the device (e.g., display  1702  in  FIG. 17B ). 
     At block  1808 , the device displays a user interface screen (e.g., as described above) in response to detecting the user movement of the device (e.g., display  1702  in  FIG. 17B ). Thus, the device can display a user interface screen automatically when the user raises the device into viewing position, rather than requiring an additional user input to power on the display when the user is viewing it. Reducing the number of inputs needed to perform an operation enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     Note that details of the processes described above with respect to process  1800  (e.g.,  FIG. 18 ) are also applicable in an analogous manner to the methods described elsewhere in this application. For example, other methods described in this application may include one or more of the characteristics of process  1800 . For example, one or more steps of process  1800  can occur prior to block  702  of process  700 , block  802  of process  800 , block  1002  of process  1000 , block  1502  of process  1500 , or block  1602  of process  1600 , as described above. For brevity, these details are not repeated below. 
     Turning now to  FIG. 19A , a user may wish for character-based user interface objects with a more natural and lifelike appearance and/or increased interactability with the user. Further, a user may wish for the character-based user interface object to act in a more dynamic manner, to interact with the user, and/or to provide event-related information to a user. Described below are context-specific user interfaces with increased interactability. Any of the techniques described below can be combined with the techniques described in International Patent Application Serial No. PCT/US2015/034604, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022203, e.g., in reference to character user interface objects. The features described herein allow a character user interface object to appear more natural and lifelike by adopting a wider range of natural motions while indicating a time. A user may wish to view representations of other events by the character user interface object. Allowing the character user interface object to react to external stimuli or internal system events portrays a more interactive character, thus depicting a closer representation of a personality. The enhanced interactivity of the character further improves the user&#39;s interactions with the device by providing additional notification that an event has occurred, the occurrence of which may not have been as apparent otherwise. A character user interface object may serve to supply notifications, reminders, and/or other information a user may wish to access from a personal electronic device, but the use of a character provides an interactive personality that the device may use to supply these items. Further, making the character responsive to internal system events (e.g., calendar events and the like) means the character is not strictly limited to responding to external user input. Put another way, the character appears to have a more lifelike personality because it responds to events not directly prompted by the immediate actions of the user. 
       FIGS. 19A-19F  show exemplary context-specific user interfaces that may be operated on device  1900 . Device  1900  may be device  100 ,  300 , or  500  in some embodiments. The electronic device has a display  1902  (e.g.,  504 ). In some embodiments, display  1902  is a touch-sensitive display. In some embodiments, device  1100  includes a rotatable input mechanism  1910   a  (e.g.,  506 ) and/or input mechanism or button  1910   b  (e.g.,  508 ). 
     In  FIG. 19A , device  1900  displays a user interface screen that includes complications  1904 ,  1906 , and  1908 , current time indicator  1904 , and character user interface object  1902   a . A character user interface object can include any representation of a character, for example a human or anthropomorphized character. In some embodiments, a character can be a cartoon figure. In some embodiments, one or more sounds corresponding to the character user interface object (e.g., speech or sound associated with the character) are played (e.g., using a speaker). 
     In  FIG. 19A , device  1900  animates character user interface object  1902   a / 1902   b  to walk from off-screen onto the middle of display  1902  and stop. In some embodiments, the animation is displayed in response to detecting a user input, e.g., powering on the device or detecting a user movement of device  1900 . 
     In  FIG. 19B , device  1900  animates character user interface object  1902   c  to react to a displayed user interface object. In this example, character user interface object  1902   c  reacts to the display of notifications dot  1912 , which indicates to the user that one or more notifications (e.g., unread notifications) have been received, such as a missed call, email, voicemail, text message, and the like. In some embodiments, character user interface object  1902   c  is animated to interact with one or more displayed user interface objects such as a complication (e.g.,  1904 ,  1906 , or  1908 , such as by climbing on or tripping over the displayed text). 
     In some embodiments, character user interface object  1902   c  is animated to interact with the current time indicator ( FIG. 19C ). In  FIG. 19C , character user interface object  1902   d  points at indicator  1914   a , e.g., at a change in time. After the animation, indicator  1914   b  is updated, e.g., as if changed by or reacting to character user interface object  1902   d.    
     In other embodiments, character user interface object  1902   e  reacts to time indicator  1914   b , e.g., by removing his hat. For example, character user interface object  1902   e  can react to a certain time of day (e.g., not an even hour or half-hour) or certain date, e.g., a time or date of significance to the character (e.g., an “Easter egg”). This increases user interactions with the device, e.g., by promoting the user to interact with the device at different times to discover an “Easter egg.” In some embodiments, device  1900  detects a user touch gesture (e.g., tap) on display  1902 ), and in response to detecting the touch gesture, device  1900  animates the character user interface object to react to the touch. 
     In some embodiments, character user interface object  1902   f  reacts to the displayed information of a complication. For example, in  FIG. 19D , character user interface object  1902   f  takes off his hat and swipes his brow because the current weather conditions are warm (as indicated by the information displayed by complication  1908   b ). This reinforces the information displayed by the complication (e.g., as obtained from the corresponding application). 
     In some embodiments, multiple animated sequences for the character user interface object can be displayed. For example, one animated sequence is shown in  FIG. 19A . In  FIG. 19E , device  1900  animates character user interface object  1902   g / 1902   h  to parachute on-screen onto the middle of display  1902  and stop. In some embodiments, the animation is displayed in response to detecting a user input, e.g., powering on the device or detecting a user movement of device  1900 . In some embodiments, one or more animated sequences for the character user interface object can be displayed in response to detecting a user interaction, such as a touch gesture on the display. 
     In some embodiments, multiple character user interface objects can be selected for display at device  1900 . The user may wish to select a different character user interface object. Any of the editing and selection techniques described herein or in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205, can be used. 
     In  FIG. 19F , the user accesses an edit mode of device  1900  through press  1922 , which in some embodiments can be a press having a duration longer than a predetermined duration (e.g., a “long press” input) or a contact having a characteristic intensity above an intensity threshold. In this example, in response to detecting press  1922 , device  1900  enters a context-specific user interface selection mode and visually distinguishes the user interface screen to indicate the selection mode. Device  1900  alerts to the user that it has entered into the selection mode by displaying smaller representation  1924  of the user interface screen, name  1928  corresponding to a name of the type of context-specific user interface currently selected, partial view  1930  of an adjacent, stored context-specific user interface (which the user could select by swiping to view the full interface and tapping to select it), and edit affordance  1926 . In order to edit the character user interface object, the user contacts edit affordance  1926  via tap  1932 . 
     In response to detecting tap  1932 , the device enters edit mode and visually distinguishes one or more aspects of the user interface for editing. In this example, character user interface object  1902   i  is selected for editing (e.g., selecting a character). Device  1900  informs the user that user interface object  1902   i  is selected for editing by visually distinguishing user interface object  1902   i  via displaying outline  1932   a  around user interface object  1902   i  and indicator  1932   b , which indicates that the character is editable. Device  1900  also displays scroll indicator  1936 , which informs the user that additional characters can be selected by scrolling and indicates the position of the character along the series of displayable characters. Device  1900  also displays paging affordance  1934 , which indicates that three options for editing different aspects of the user interface can be selected (e.g., by swiping). In this example, the options include the character, the application associated with various complications, and one or more colors (e.g., a color associated with the character user interface object and/or an additional display element). 
     To edit a different aspect of the interface, the user swipes display  1902 , e.g., via swipe. To change the character, the user rotates  1910   a  via scroll  1938 . In response to detecting scroll  1938 , device  1900  ceases to display  1902   i  and displays character user interface object  1940  ( FIG. 19F ). Indicator  1932   b  is also updated to reflect the character. Scroll indicator  1942  is also updated to indicate the position of the new character along the series of selectable characters. In some embodiments, the user can then exit edit mode and display the edited user interface screen. In some embodiments, upon exiting edit mode, the device saves the edited user interface screen in memory, e.g., such that it can be subsequently selected in selection mode, e.g., as described in International Patent Application Serial No. PCT/US2015/034607, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022205 (see, e.g., display  1322  in  FIG. 13 ). 
     In any of the embodiments described herein, or any of the embodiments described in International Patent Application Serial No. PCT/US2015/034604, titled “Context-Specific User Interfaces,” filed Jun. 7, 2015, published as WIPO Publication No. WO/2016/022203, a context-specific user interface displays one or more colors indicative of wireless communication functionality. For example, a context-specific user interface can include a color only for devices capable of long term evolution (LTE) wireless communication. In some embodiments, a context-specific user interface displays one or more user interface objects that indicate wireless connectivity status. For example, one or more dots can be displayed, where a larger number of dots indicates higher signal strength. In some embodiments, a color of the one or more dots indicates the type of wireless communication that the device is currently using (e.g., one color for LTE and another color for WiFi). In some embodiments, the one or more dots can be an affordance that the user can select (e.g., by tapping). In response to detecting the user selection (e.g., tap), the device displays a user interface screen for changing a wireless communication setting (e.g., turning off/on LTE or WiFi).
