Description:
RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Application Ser. No. 62/679,961, filed Jun. 3, 2018, entitled “Devices and Methods for Integrating Video with User Interface Navigation,” which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that provide videos, and more particularly, to devices and methods that provide video while navigating between user interfaces. 
     BACKGROUND 
     The use of portable electronic devices has increased significantly in recent years, as old features are improved and new features are added. For example, playing video on portable electronic devices has gotten easier and more efficient, which in turn, has helped to increase the popularity and use of these portable electronic devices. 
     But current devices and methods for integrating video with user interface navigation are cumbersome and inefficient. For example, if the device is playing video using a first application and attempts to navigate to a second application, the device will cease playing the video while navigating to the second application, thereby preventing the user from continuing to watch the video. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with more efficient methods and interfaces for integrating video with user interface navigation. Such methods and interfaces optionally complement or replace conventional methods for integrating video with user interface navigation. Such methods and interfaces reduce the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. 
     The above deficiencies and other problems associated with integrating video with user interface navigation are reduced or eliminated by the disclosed electronic devices. In some embodiments, the device includes a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device includes a personal electronic device (e.g., a wearable electronic device, such as a watch). In some embodiments, the device has (and/or is in communication with) a display generation component and one or more input devices. In some embodiments, the device has (and/or is in communication with) a touchpad. In some embodiments, the device has (and/or is in communication with) a touch-sensitive display (also known as a “touch screen” or “touch screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI in part through stylus and/or finger contacts and gestures on the touch-sensitive surface. In some embodiments, in addition to digital video playing, the functions optionally include game playing, image editing, drawing, presenting, word processing, spreadsheet making, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or note taking. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors. 
     In accordance with some embodiments, a method is performed at an electronic device with a touch-sensitive display. The method includes displaying, on the touch-sensitive display, a user interface for an application. The method further includes, while displaying the user interface for the application, detecting a touch gesture that includes movement of a contact on the touch-sensitive display at least partially over the user interface for the application. The method further includes, in response to detecting the touch gesture, in accordance with a determination that the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, concurrently displaying a home screen user interface and a representation of the video that is playing in the application. The method further includes, in accordance with a determination that the touch gesture meets the first system navigation criteria and there is not video playing in the application when the touch gesture is detected, displaying the home screen user interface without displaying the representation of the video. 
     In accordance with some embodiments, an electronic device includes a display, an optional touch-sensitive surface, one or more optional sensors to detect intensities of contacts with the touch-sensitive surface, one or more processors, memory, and one or more programs. The one or more programs are stored in the memory and configured to be executed by the one or more processors. The one or more programs include instructions for performing the operations of any of the methods described herein. In accordance with some embodiments, a computer readable storage medium has stored therein instructions which when executed by an electronic device with a display, an optional touch-sensitive surface, and one or more optional sensors to detect intensities of contacts with the touch-sensitive surface, cause the device to perform the operations of any of the methods described herein. In accordance with some embodiments, a graphical user interface on an electronic device that includes memory and one or more processors to execute one or more programs stored in the memory includes one or more of the elements displayed in any of the methods described herein, which are updated in response to inputs, as described in any of the methods described herein. In accordance with some embodiments, an electronic device includes a display, an optional touch-sensitive surface, one or more optional sensors to detect intensities of contacts with the touch-sensitive surface, and means for performing the operations of any of the methods described herein. In accordance with some embodiments, an information processing apparatus, for use in an electronic device that includes a display, an optional touch-sensitive surface, and one or more optional sensors to detect intensities of contacts with the touch-sensitive surface, includes means for performing the operations of any of the methods described herein. 
     Thus, electronic devices are provided with faster, more efficient methods and interfaces for integrating video with user interface navigation, thereby increasing the effectiveness, efficiency, and user satisfaction with such devices. Such methods and interfaces may complement or replace conventional methods for integrating video with user interface navigation.

     Touch-sensitive display system  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch-sensitive display system  112 . Touch-sensitive display system  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user interface objects. As used herein, the term “affordance” refers to a user-interactive graphical user interface object (e.g., a graphical user interface object that is configured to respond to inputs directed toward the graphical user interface object). Examples of user-interactive graphical user interface objects include, without limitation, a button, slider, icon, selectable menu item, switch, hyperlink, or other user interface control. 
     Touch-sensitive display system  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch-sensitive display system  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch-sensitive display system  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system  112 . In some embodiments, a point of contact between touch-sensitive display system  112  and the user corresponds to a finger of the user or a stylus.

The user optionally makes contact with touch-sensitive display system  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad 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.

In some embodiments, an optical sensor is located on the back of device  100 , opposite touch-sensitive display system  112  on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.).

     Device  100  optionally also includes one or more tactile output generators  167 .  FIG.  1 A  shows a tactile output generator coupled with haptic feedback controller  161  in I/O subsystem  106 .

In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. 
     Contact/motion module  130  optionally detects contact with touch-sensitive display system  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus. 
     In some embodiments, detecting a finger tap gesture depends on the length of time between detecting the finger-down event and the finger-up event, but is independent of the intensity of the finger contact between detecting the finger-down event and the finger-up event. In some embodiments, a tap gesture is detected in accordance with a determination that the length of time between the finger-down event and the finger-up event is less than a predetermined value (e.g., less than 0.1, 0.2, 0.3, 0.4 or 0.5 seconds), independent of whether the intensity of the finger contact during the tap meets a given intensity threshold (greater than a nominal contact-detection intensity threshold), such as a light press or deep press intensity threshold. Thus, a finger tap gesture can satisfy particular input criteria that do not require that the characteristic intensity of a contact satisfy a given intensity threshold in order for the particular input criteria to be met. For clarity, the finger contact in a tap gesture typically needs to satisfy a nominal contact-detection intensity threshold, below which the contact is not detected, in order for the finger-down event to be detected. A similar analysis applies to detecting a tap gesture by a stylus or other contact. In cases where the device is capable of detecting a finger or stylus contact hovering over a touch sensitive surface, the nominal contact-detection intensity threshold optionally does not correspond to physical contact between the finger or stylus and the touch sensitive surface. 
     The same concepts apply in an analogous manner to other types of gestures. For example, a swipe gesture, a pinch gesture, a depinch gesture, and/or a long press gesture are optionally detected based on the satisfaction of criteria that are either independent of intensities of contacts included in the gesture, or do not require that contact(s) that perform the gesture reach intensity thresholds in order to be recognized. For example, a swipe gesture is detected based on an amount of movement of one or more contacts; a pinch gesture is detected based on movement of two or more contacts towards each other; a depinch gesture is detected based on movement of two or more contacts away from each other; and a long press gesture is detected based on a duration of the contact on the touch-sensitive surface with less than a threshold amount of movement. As such, the statement that particular gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met means that the particular gesture recognition criteria are capable of being satisfied if the contact(s) in the gesture do not reach the respective intensity threshold, and are also capable of being satisfied in circumstances where one or more of the contacts in the gesture do reach or exceed the respective intensity threshold. In some embodiments, a tap gesture is detected based on a determination that the finger-down and finger-up event are detected within a predefined time period, without regard to whether the contact is above or below the respective intensity threshold during the predefined time period, and a swipe gesture is detected based on a determination that the contact movement is greater than a predefined magnitude, even if the contact is above the respective intensity threshold at the end of the contact movement. Even in implementations where detection of a gesture is influenced by the intensity of contacts performing the gesture (e.g., the device detects a long press more quickly when the intensity of the contact is above an intensity threshold or delays detection of a tap input when the intensity of the contact is higher), the detection of those gestures does not require that the contacts reach a particular intensity threshold so long as the criteria for recognizing the gesture can be met in circumstances where the contact does not reach the particular intensity threshold (e.g., even if the amount of time that it takes to recognize the gesture changes). 
     Contact intensity thresholds, duration thresholds, and movement thresholds are, in some circumstances, combined in a variety of different combinations in order to create heuristics for distinguishing two or more different gestures directed to the same input element or region so that multiple different interactions with the same input element are enabled to provide a richer set of user interactions and responses. The statement that a particular set of gesture recognition criteria do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met does not preclude the concurrent evaluation of other intensity-dependent gesture recognition criteria to identify other gestures that do have criteria that are met when a gesture includes a contact with an intensity above the respective intensity threshold. For example, in some circumstances, first gesture recognition criteria for a first gesture—which do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met—are in competition with second gesture recognition criteria for a second gesture—which are dependent on the contact(s) reaching the respective intensity threshold. In such competitions, the gesture is, optionally, not recognized as meeting the first gesture recognition criteria for the first gesture if the second gesture recognition criteria for the second gesture are met first. For example, if a contact reaches the respective intensity threshold before the contact moves by a predefined amount of movement, a deep press gesture is detected rather than a swipe gesture. Conversely, if the contact moves by the predefined amount of movement before the contact reaches the respective intensity threshold, a swipe gesture is detected rather than a deep press gesture. Even in such circumstances, the first gesture recognition criteria for the first gesture still do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the first gesture recognition criteria to be met because if the contact stayed below the respective intensity threshold until an end of the gesture (e.g., a swipe gesture with a contact that does not increase to an intensity above the respective intensity threshold), the gesture would have been recognized by the first gesture recognition criteria as a swipe gesture. As such, particular gesture recognition criteria that do not require that the intensity of the contact(s) meet a respective intensity threshold in order for the particular gesture recognition criteria to be met will (A) in some circumstances ignore the intensity of the contact with respect to the intensity threshold (e.g. for a tap gesture) and/or (B) in some circumstances still be dependent on the intensity of the contact with respect to the intensity threshold in the sense that the particular gesture recognition criteria (e.g., for a long press gesture) will fail if a competing set of intensity-dependent gesture recognition criteria (e.g., for a deep press gesture) recognize an input as corresponding to an intensity-dependent gesture before the particular gesture recognition criteria recognize a gesture corresponding to the input (e.g., for a long press gesture that is competing with a deep press gesture for recognition). 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch-sensitive display system  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.

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

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely examples. For example, other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an example user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450 . Although many of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or the touch screen in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “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 or a stylus 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 or a sum) 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 readily 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). 
     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 is 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 thresholds 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). 
     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, a value produced by low-pass filtering the intensity of the contact over a predefined period or starting at a predefined time, 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 may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first intensity 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 intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be 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 may be 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 user interface figures described herein optionally include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT 0 , a light press intensity threshold IT L , a deep press intensity threshold IT D  (e.g., that is at least initially higher than IT L ), and/or one or more other intensity thresholds (e.g., an intensity threshold IT H  that is lower than IT L )). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. 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 IT 0  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. 
     In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some “light press” inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some “deep press” inputs, the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold for a light press, triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms (milliseconds) in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental recognition of deep press inputs. As another example, for some “deep press” inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental deep press inputs. For other deep press inputs, the response to detection of a deep press input does not depend on time-based criteria. 
     In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Example factors are described in U.S. patent application Ser. Nos. 14/399,606 and 14/624,296, which are incorporated by reference herein in their entireties. 
     For example,  FIG.  4 C  illustrates a dynamic intensity threshold  480  that changes over time based in part on the intensity of touch input  476  over time. Dynamic intensity threshold  480  is a sum of two components, first component  474  that decays over time after a predefined delay time p1 from when touch input  476  is initially detected, and second component  478  that trails the intensity of touch input  476  over time. The initial high intensity threshold of first component  474  reduces accidental triggering of a “deep press” response, while still allowing an immediate “deep press” response if touch input  476  provides sufficient intensity. Second component  478  reduces unintentional triggering of a “deep press” response by gradual intensity fluctuations of in a touch input. In some embodiments, when touch input  476  satisfies dynamic intensity threshold  480  (e.g., at point  481  in  FIG.  4 C ), the “deep press” response is triggered. 
       FIG.  4 D  illustrates another dynamic intensity threshold  486  (e.g., intensity threshold I D ).  FIG.  4 D  also illustrates two other intensity thresholds: a first intensity threshold I H  and a second intensity threshold I L . In  FIG.  4 D , although touch input  484  satisfies the first intensity threshold I H  and the second intensity threshold I L  prior to time p2, no response is provided until delay time p2 has elapsed at time  482 . Also in  FIG.  4 D , dynamic intensity threshold  486  decays over time, with the decay starting at time  488  after a predefined delay time p1 has elapsed from time  482  (when the response associated with the second intensity threshold I L  was triggered). This type of dynamic intensity threshold reduces accidental triggering of a response associated with the dynamic intensity threshold I D  immediately after, or concurrently with, triggering a response associated with a lower intensity threshold, such as the first intensity threshold I H  or the second intensity threshold I L . 
       FIG.  4 E  illustrate yet another dynamic intensity threshold  492  (e.g., intensity threshold I D ). In  FIG.  4 E , a response associated with the intensity threshold I L  is triggered after the delay time p2 has elapsed from when touch input  490  is initially detected. Concurrently, dynamic intensity threshold  492  decays after the predefined delay time p1 has elapsed from when touch input  490  is initially detected. So a decrease in intensity of touch input  490  after triggering the response associated with the intensity threshold I L , followed by an increase in the intensity of touch input  490 , without releasing touch input  490 , can trigger a response associated with the intensity threshold I D  (e.g., at time  494 ) even when the intensity of touch input  490  is below another intensity threshold, for example, the intensity threshold I L . 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold IT L  to an intensity between the light press intensity threshold IT L  and the deep press intensity threshold IT D  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 IT D  to an intensity above the deep press intensity threshold IT D  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 IT 0  to an intensity between the contact-detection intensity threshold IT 0  and the light press intensity threshold IT L  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 IT 0  to an intensity below the contact-detection intensity threshold IT 0  is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT 0  is zero. In some embodiments, IT 0  is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact. 
     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., the respective operation is performed on 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., the respective operation is performed on an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on 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 description 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: 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, 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 described above, in some embodiments, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a first intensity threshold being met and a second intensity threshold being met). 
     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. Using tactile outputs to provide haptic feedback to a user 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, a tactile output pattern specifies characteristics of a tactile output, such as the amplitude of the tactile output, the shape of a movement waveform of the tactile output, the frequency of the tactile output, and/or the duration of the tactile output. 
     When tactile outputs with different tactile output patterns are generated by a device (e.g., via one or more tactile output generators that move a moveable mass to generate tactile outputs), the tactile outputs may invoke different haptic sensations in a user holding or touching the device. While the sensation of the user is based on the user&#39;s perception of the tactile output, most users will be able to identify changes in waveform, frequency, and amplitude of tactile outputs generated by the device. Thus, the waveform, frequency and amplitude can be adjusted to indicate to the user that different operations have been performed. As such, tactile outputs with tactile output patterns that are designed, selected, and/or engineered to simulate characteristics (e.g., size, material, weight, stiffness, smoothness, etc.); behaviors (e.g., oscillation, displacement, acceleration, rotation, expansion, etc.); and/or interactions (e.g., collision, adhesion, repulsion, attraction, friction, etc.) of objects in a given environment (e.g., a user interface that includes graphical features and objects, a simulated physical environment with virtual boundaries and virtual objects, a real physical environment with physical boundaries and physical objects, and/or a combination of any of the above) will, in some circumstances, provide helpful feedback to users that reduces input errors and increases the efficiency of the user&#39;s operation of the device. Additionally, tactile outputs are, optionally, generated to correspond to feedback that is unrelated to a simulated physical characteristic, such as an input threshold or a selection of an object. Such tactile outputs will, in some circumstances, provide helpful feedback to users that reduces input errors and increases the efficiency of the user&#39;s operation of the device. 
     In some embodiments, a tactile output with a suitable tactile output pattern serves as a cue for the occurrence of an event of interest in a user interface or behind the scenes in a device. Examples of the events of interest include activation of an affordance (e.g., a real or virtual button, or toggle switch) provided on the device or in a user interface, success or failure of a requested operation, reaching or crossing a boundary in a user interface, entry into a new state, switching of input focus between objects, activation of a new mode, reaching or crossing an input threshold, detection or recognition of a type of input or gesture, etc. In some embodiments, tactile outputs are provided to serve as a warning or an alert for an impending event or outcome that would occur unless a redirection or interruption input is timely detected. Tactile outputs are also used in other contexts to enrich the user experience, improve the accessibility of the device to users with visual or motor difficulties or other accessibility needs, and/or improve efficiency and functionality of the user interface and/or the device. Tactile outputs are optionally accompanied with audio outputs and/or visible user interface changes, which further enhance a user&#39;s experience when the user interacts with a user interface and/or the device, and facilitate better conveyance of information regarding the state of the user interface and/or the device, and which reduce input errors and increase the efficiency of the user&#39;s operation of the device. 
     User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device  100  or device  300 , with a display, a touch-sensitive surface, (optionally) one or more tactile output generators for generating tactile outputs, and (optionally) one or more sensors to detect intensities of contacts with the touch-sensitive surface. 
     FIGS.  5 A 1 - 5 A 37  illustrate example user interfaces for integrating video with user interface navigation in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  6 A- 6 C . For convenience of explanation, some of the embodiments will be discussed with reference to operations performed on a device with a touch-sensitive display system  112 . In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 . However, analogous operations are, optionally, performed on a device with a display  450  and a separate touch-sensitive surface  451  in response to detecting the contacts on the touch-sensitive surface  451  while displaying the user interfaces shown in the figures on the display  450 , along with a focus selector. 
     FIG.  5 A 1 - 5 A 2  illustrate an example embodiment where the electronic device scrolls through an application user interface in response to a swipe gesture. In FIG.  5 A 1 , a web browsing user interface  5002  is displayed. The web browsing user interface  5002  includes an embedded video that is currently not playing. A contact  5004  traveling upwards is detected on the web browsing user interface  5002  in FIG.  5 A 1  and lift off of the contact is detected in FIG.  5 A 2 . The contact  5004  does not meet system gesture criteria because the contact  5004  originates at a portion of the touch screen  112  other than the edge of the touch screen  112 . In response to the upward drag or swipe gesture by contact  5004 , the web browsing user interface  5002  scrolls upward. 
     FIG.  5 A 3 - 5 A 7  illustrate an example embodiment where the display transitions to an application-switching user interface without playing a video from an application user interface. In FIG.  5 A 3 , a web browsing user interface  5002  is displayed. The web browsing user interface  5002  includes an embedded video that is currently not playing. A contact  5006  traveling upwards is detected, which starts at a bottom edge of the touch screen  112 . The gesture by contact  5006  meets system gesture criteria because it is a swipe gesture that originates at the edge of the touch screen  112 . In FIG.  5 A 4 , as the contact  5006  moves upwards on the touch screen  112 , the application dock  5008 , including one or more application icons, slides onto the display. In FIG.  5 A 5 , as the contact  5006  continues to move upwards, the web browsing user interface  5002  is replaced by a web browsing card  5010  that is a representation (e.g., snapshot) of the web browsing user interface  5002 . During the entirety of the gesture by contact  5006 , the video is not playing in the web browsing user interface  5002 . As the contact  5006  moves upwards on the touch screen  112 , in FIG.  5 A 5 , web browsing card  5010  shrinks dynamically, revealing a blurred view of the home screen user interface  5012  in the background. In FIG.  5 A 6 , a threshold for displaying the application-switching user interface is met. In response, the second card (e.g., search card  5014  that is a representation of a search user interface) is displayed along with web browsing card  5010  in a first application-switching user interface  5026 . In FIG.  5 A 7 , upon liftoff of contact  5006 , the web browsing card  5010  becomes one of a number of cards (e.g., books card  5016 , maps card  5018 , calendar card  5020  and setting card  5022 , which are reduced-scale representations of corresponding applications) displayed within a second application-switching user interface  5024 . 
     FIGS.  5 A 8 - 5 A 10  illustrate an example embodiment where the device navigates to the home screen user interface without playing a video. FIGS.  5 A 8 - 5 A 10  are displayed after the user interface of FIG.  5 A 6 . In FIG.  5 A 8 , as the contact  5006  continues to move upward towards the top edge of the touch screen  112 , the criteria for transitioning to the home screen user interface  5012  are met. The application-switching user interface  5026  is deactivated and the search card  5014  disappears. A home screen user interface  5012  is displayed. The web browsing card  5010  shrinks and continues to track the location of the contact  5006 . In FIG.  5 A 9 , upon liftoff of the contact, the web browsing card  5010  shrinks and travels towards the location of web browsing icon  5028  associated with the web browsing application. The web browsing card  5010  transforms into the web browsing icon  5028 . In FIG.  5 A 10 , after reaching the web browsing icon  5028 , the web browsing card  5010  disappears and the home screen user interface  5012  is displayed without any obscuring (e.g., blurring and/or darkening). Although in FIG.  5 A 9  the web browsing card  5010  travels towards the web browsing icon  5028  associated with the web browsing application in the application dock  5008  during the transition to the home screen user interface, in some embodiments, the web browsing icon  5028  is not shown in the dock until the end of the transition, and the web browsing card  5010  travels towards a bottom portion of the touch screen  112 . 
     FIGS.  5 A 11 - 5 A 17  illustrate an example embodiment where a video is played in an application user interface or in a picture-in-picture (“PiP”) user interface on the display. In FIG.  5 A 11 , a web browsing user interface  5002  is displayed. The web browsing user interface  5002  includes a play affordance  5030  that, when activated, causes a video to play in the web browsing user interface  5002 . A gesture by contact  5032  (e.g., a tap gesture) is detected at a play affordance  5030  that causes the web browsing application to play the video. In FIG.  5 A 12 , the video is playing in the web browsing user interface  5002 . When the video is playing in the web browsing user interface  5002 , the web browsing user interface  5002  displays a picture-in-picture (“PiP”) affordance  5034 . A gesture by contact  5035  (e.g., a tap gesture) is detected at the PiP affordance  5034 . In FIG.  5 A 13 , in response to activation of the PiP affordance  5034 , a PiP user interface  5036  is displayed. The PiP user interface  5036  overlays the web browsing user interface  5002 . The PiP user interface  5036  includes a pause affordance  5038 , an exit affordance  5040 , and “expand to full screen” affordance  5042 . In the web browsing user interface  5002 , a message is displayed notifying the user that a representation of the video that was previously playing in web browsing user interface is now playing in the PiP user interface  5036 . In FIG.  5 A 13 , a gesture by contact  5044  is initially detected on the PiP user interface  5036 . In FIGS.  5 A 14 - 5 A 15 , the gesture by contact  5044  is a drag gesture moving towards a bottom-right portion of the touch screen  112 . As the contact  5044  moves across the touch screen  112 , the PiP user interface  5036  moves with the contact  5044 . At  5 A 16 , the gesture by contact  5044  ends when liftoff of the contact  5044  is detected. The PiP user interface  5036  remains at its current position until a command is received to move the PiP user interface  5036 . A new gesture by contact  5046  is detected at the “expand to full screen” affordance in the PiP user interface  5036 . In response, in FIG.  5 A 17 , the PiP user interface  5036  disappears and is replaced by web browsing user interface  5002 . The video previously playing in the PiP user interface  5036  continues playing in the web browsing user interface  5002 . 
     FIGS.  5 A 17 - 5 A 22  illustrate an example embodiment where the display transitions to application-switching user interface  5024  and plays a video in a card in the application-switching user interface  5024 . In FIG.  5 A 17 , the web browsing user interface  5002  is displayed. The web browsing user interface  5002  includes an embedded video that is currently playing. A gesture by contact  5048  traveling upwards is detected at the web browsing user interface  5002 . The gesture by contact  5048  meets system gesture criteria because the gesture by contact  5048  is a swipe gesture that originates at the edge of the touch screen  112 . In FIG.  5 A 18 , as the contact  5048  moves upwards on the touch screen  112 , the application dock  5008  slides onto the display. In FIG.  5 A 19 , as the contact  5048  continues to move upwards, the web browsing user interface  5002  is replaced by the web browsing card  5010  with a blurred view of the home screen user interface  5012  in the background. During the entirety of the gesture by contact  5048 , the video is playing in the web browsing user interface  5002  and the web browsing card  5010 . As the contact  5048  moves upwards on the touch screen  112 , in FIG.  5 A 20 , web browsing card  5010  shrinks dynamically. In FIG.  5 A 20 , as the contact  5048  moves towards a middle of the touch screen  112 , the threshold for displaying the application-switching user interface  5026  is met. In response, a search card  5014  is displayed along with the web browsing card  5010  in application switching user interface  5026 . In FIG.  5 A 21 , upon liftoff of the contact  5048 , the web browsing card  5010  becomes one of a number of cards (e.g., books card, maps card, calendar card and setting card) displayed within application-switching user interface  5024 . As shown in FIG.  5 A 22 , because the video was playing when the gesture by contact  5048  was detected and because system gesture criteria were met by the gesture, after liftoff of the contact  5048 , a representation of the video is still playing in the web browsing card  5010 . Although the representation of the video is playing in the web browsing card  5010  in this example embodiment, in other embodiments, the representation of the video is playing in a PiP user interface  5036  separate from the web browsing card  5010  in the application-switching user interface  5024 . 
     FIGS.  5 A 23 - 5 A 25  illustrate an example embodiment where the device navigates to the home screen user interface  5012  and displays a PiP user interface  5036  that continues to play a representation of the video at the most recent location of the PiP user interface  5036  after liftoff of the contact  5048 . FIGS.  5 A 23 - 5 A 25  are displayed after the user interface of FIG.  5 A 20 . In FIG.  5 A 23 , as the gesture by contact  5048  continues to move upward towards the top edge of the touch screen  112 , the criteria for transitioning to the home screen user interface  5012  (e.g., movement past a predetermined distance in a predetermined direction) are met. The application-switching user interface  5026  is deactivated and the search card  5014  disappears. The web browsing card  5010  shrinks and continues to track the location of the contact  5048 . The representation of the video continues playing in the web browsing card  5010 . In FIG.  5 A 24 , upon liftoff of the contact  5048 , the web browsing card  5010  shrinks and travels towards the web browsing icon  5028  associated with the web browsing application. The web browsing card  5010  transforms into the web browsing icon  5028 . Also, upon liftoff of the contact  5048 , the PiP user interface  5036  is initially displayed at the location of the liftoff of the contact  5048 . The PiP user interface  5036  is optionally displayed as a transformation of web browsing card  5010  or a transformation of the embedded video playing in the web browsing card  5010 . As shown in FIG.  5 A 24 - 5 A 25 , the PiP user interface  5036  transitions to the last displayed position of the PiP user interface  5036 , e.g., at the bottom right corner of the touch screen  112 . Because the video was playing when the gesture by contact  5048  was detected and because system gesture criteria were met, the representation of the video continues playing in the PiP user interface  5036  after liftoff of the contact  5048 . In FIG.  5 A 25 , after reaching the location of the web browsing icon  5028 , the web browsing card  5010  disappears and the home screen user interface  5012  is clearly displayed, without any obscuring (e.g., blurring and/or darkening). 
     FIGS.  5 A 26 - 5 A 27  illustrate an example embodiment where the display transitions to the application-switching user interface  5024  and displays a PiP user interface  5036  that continues to play a representation of the video. FIGS.  5 A 26 - 5 A 29  are displayed after the user interface of FIG.  5 A 20 . In FIG.  5 A 26 , in response to liftoff of the contact  5048 , an application-switching user interface  5024  is displayed. The web browsing card  5010  transitions to a predetermined position in the upper-right corner of the application-switching user interface  5024 . In addition, upon liftoff of the contact  5048 , a PiP user interface  5036  is initially displayed at a position of the contact  5048  at liftoff and transitions to a last displayed position of the PiP user interface  5036 , e.g., at the bottom right corner of the touch screen  112 . As shown in FIG.  5 A 27 , because the video was playing when the gesture by contact  5048  was detected and because system gesture criteria were met, the representation of the video continues playing in the PiP user interface  5036  while the application-switching user interface  5024  is concurrently displayed. 
     FIGS.  5 A 27 - 5 A 29  illustrate an example embodiment where, while a representation of the video continues playing in the PiP user interface  5036 , a second application that corresponds to a card selected in the application-switching user interface  5024  is displayed with the PiP user interface  5036 . In FIG.  5 A 27 , the application-switching user interface  5024  is displayed concurrently with the PiP user interface  5036 , which is displayed at the bottom right corner of the touch screen  112 . The representation of the video continues to play in the PiP user interface  5036 . A gesture by contact  5050  (e.g., a tap gesture) is detected at a calendar card  5020 . In FIG.  5 A 28 , in response to detecting the gesture by contact  5050 , a calendar user interface  5054  is displayed on the touch screen  112 . In FIGS.  5 A 28 - 5 A 29 , the PiP user interface  5036  remains displayed at the bottom right corner of the touch screen  112  and the representation of the video continues to play in the PiP user interface  5036 . 
     FIGS.  5 A 30 - 5 A 31  illustrate an example embodiment where, while the gesture by contact  5048  is moving an application card (e.g., web browsing card  5010 ), the size and position of the application card corresponds to certain characteristics of the contact. FIGS.  5 A 30 - 5 A 31  are displayed after the user interface of FIG.  5 A 23 . In FIG.  5 A 30 , the gesture by contact  5048  continues moving and the web browsing card  5010  continues following the contact  5048  as the contact moves. As shown in FIG.  5 A 31 , the web browsing card  5010  optionally changes shape when certain contact position criteria is met. For example, in FIG.  5 A 31 , the web browsing card  5010  shrinks in size as the contact  5048  moves towards an edge of the touch screen  112 . 
     FIGS.  5 A 32 - 5 A 33  illustrate an example embodiment where the device navigates back to the home screen user interface and displays a PiP user interface  5036  that continues to play the representation of the video at or proximate to the location of the contact  5048  at liftoff. In FIG.  5 A 32 , upon liftoff of the contact  5048 , the web browsing card  5010  shrinks and travels towards the location of the web browsing icon  5028  associated with the web browsing application. Similar to other embodiments described above, the web browsing card  5010  transforms into the web browsing icon  5028 . Also, upon liftoff of the contact  5048 , the PiP user interface  5036  is initially displayed at the location corresponding to the liftoff of the contact  5048 . As shown in FIG.  5 A 32 , the PiP user interface  5036  transitions to an upper right corner of the touch screen  112  proximate to the location of the contact  5048  at liftoff. In FIG.  5 A 33 , after reaching the web browsing icon  5028 , the web browsing card  5010  disappears and the home screen user interface  5012  is clearly displayed, without any obscuring (e.g., blurring and/or darkening). The representation of the video continues playing in the PiP user interface  5036  after liftoff of the contact  5048 . 
     FIGS.  5 A 34 - 5 A 37  illustrate an example embodiment where the device, in response to the gesture by contact  5048  ending at an edge of the display, displays a minimized representation of the video and continues to play the representation of the video. FIGS.  5 A 34 - 5 A 37  are displayed after the user interface of FIG.  5 A 31 . In FIG.  5 A 34 , the gesture by contact  5048  is moving towards an edge of the touch screen  112  and the web browsing card  5010  continues following the contact  5048 . The video continues to play in the web browsing card  5010 . Upon reaching the edge of the touch screen  112 , as shown in FIGS.  5 A 34 - 5 A 35 , the web browsing card  5010  disappears and is replaced by a minimized representation of the video  5058 , which includes an expand affordance (e.g., a chevron) and which continues to play the representation of the video. In some embodiments, the minimized representation of the video continues to play the sound from the video and just displays a portion of the video (e.g., as a blurred background behind the expand affordance). When the expand affordance is activated (e.g., by a gesture by contact  5060  moving in a leftward direction in FIG.  5 A 36 ), a PiP user interface  5036  is displayed on the touch screen  112  as shown in FIG.  5 A 37 . The representation of the video previously playing in the web browsing card  5010  continues to play in the minimized representation of the video  5058  (FIGS.  5 A 35 - 5 A 36 ) and in the PiP user interface  5036  (FIG.  5 A 37 ). 
       FIGS.  6 A- 6 C  are flow diagrams illustrating a method of integrating video with user interface navigation, in accordance with some embodiments. Although some of the examples which follow will be given with reference to inputs on a touch-sensitive display in which a touch-sensitive surface and a display are combined, in some embodiments, the device detects inputs on a touch-sensitive surface  451  that is separate from the display  450 , as shown in  FIG.  4 B . 
     In some embodiments, method  6000  is performed by an electronic device (e.g., portable multifunction device  100 ,  FIG.  1 A ) and/or one or more components of the electronic device (e.g., I/O subsystem  106 , operating system  126 , etc.). In some embodiments, method  6000  is governed by instructions that are stored in a non-transitory computer-readable storage medium and that are executed by one or more processors of a device, such as the one or more processors  122  of device  100  ( FIG.  1 A ). For ease of explanation, the following describes method  6000  as performed by device  100 . In some embodiments, with reference to  FIG.  1 A , the operations of method  6000  are performed by or use, at least in part, operating system  126 , communication module  128 , and/or graphics module  132 , as well as a touch-sensitive display (e.g., touch screen  112 ). Some operations in method  6000  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, method  6000  (and associated interfaces) provides an intuitive way to integrate video playback with user interface navigation. Automatically providing a representation of a currently playing video (e.g., a reduced-scale representation) while the device  100  navigates from a first application to a home screen and possibly to other user interfaces (e.g., an application-switching user interface and/or a user interface in a second application) enhances the operability of the device by enabling a user to continue to watch the representation of the video while navigating elsewhere, without requiring further user inputs. The method reduces the number, extent, and/or nature of the inputs from a user for providing a representation of a video while navigating between user interfaces, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, providing a representation of a video while navigating between user interfaces faster and more efficiently conserves power and increases the time between battery charges 
     At an electronic device with a touch-sensitive display, the device  100  displays ( 6002 ), on the touch-sensitive display, a user interface for an application (e.g., a user interface that includes a video, which is either currently playing or not currently playing). 
     While displaying the user interface for the application, the device  100  detects ( 6004 ) a touch gesture that includes movement of a contact on the touch-sensitive display at least partially over the user interface for the application. 
     In some embodiments, the touch gesture includes ( 6006 ) a swipe gesture that starts at an edge of the touch-sensitive display. For example, as shown in FIGS.  5 A 3  and  5 A 17 , the touch gesture is a swipe gesture by contact  5006  or contact  5048 , respectively, that starts at the bottom edge of the display and moves upward. 
     In some embodiments, a swipe gesture that starts at an edge of the display is used to navigate to the home screen, to an application-switching user interface, or to a second application, depending on other characteristics of the gesture (e.g., depending on the speed, direction, and/or location of the contact in the gesture at lift off). Using the same gesture to also display a representation of the video (if the video is currently playing) eliminates the need for additional inputs to display the representation of the video. Reducing the number of inputs needed to perform an operation enhances the operability of the device  100  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  100 ). 
     In response to detecting ( 6008 ) the touch gesture, in accordance with a determination that the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, the device  100  concurrently displays ( 6010 ) a home screen user interface and a representation of the video that is playing in the application. For example, in FIGS.  5 A 17 - 5 A 20  and  5 A 23 - 5 A 25 , a swipe gesture  5048  is detected at the edge of the touch screen  112  while a video is playing in web browsing user interface  5002 . As shown in FIG.  5 A 23 , upon the swipe gesture by contact  5048  moving a predetermined distance in a predetermined direction, system navigation criteria are met. In response, the device  100  displays a home screen user interface  5012  and a PiP user interface  5036 , which includes a (reduced-scale) representation of the video. In some embodiments, the device  100  displays an animation in which a representation of the user interface for the application transitions to become the representation of the video that is concurrently displayed with the home screen user interface. In some embodiments, the device  100  displays an animation in which the video in the user interface for the application transitions to become the representation of the video that is concurrently displayed with the home screen user interface. For example, in FIGS.  5 A 23 - 5 A 25 , the device  100  displays an animation in which web browsing card  5010  (e.g., a representation of the user interface) transitions to become a PiP user interface  5036  (e.g., the video portion of the web browsing card  5010  pops out and transforms into the PiP user interface  5036  or the entire web browsing card  5010  transforms into the PiP user interface  5036 ). 
     In some embodiments, when there is video playing in the application when the touch gesture is detected, a displayed size of the representation of the video is ( 6012 ) dynamically adjusted during the touch gesture (e.g., in accordance with the movement of the contact in the touch gesture). For example, in FIGS.  5 A 30 - 5 A 31 , a displayed size of web browsing card  5010  playing an embedded video shrinks as the gestures  5048  moves towards an upper edge of the touch screen  112  and the representation of the video in the web browsing card  5010  also shrinks accordingly. Dynamically adjusting the displayed size of the representation of the video provides visual feedback to the user as the touch gesture progresses. Providing improved feedback enhances the operability of the device  100  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  100 ). 
     In some embodiments, when there is video playing in the application when the touch gesture is detected, the representation of the video is ( 6014 ) played continuously during the touch gesture; and the representation of the video continues to be played when the home screen user interface and the representation of the video are concurrently displayed. For example, in FIGS.  5 A 17 - 5 A 20  and  5 A 23 - 25 , during a drag gesture by contact  5048 , an embedded video is playing in web browsing user interface  5002 . As shown in FIG.  5 A 23 , upon the drag gesture by contact  5048  moving a predetermined distance in a predetermined direction, system navigation criteria are met. In response, the device  100  displays a home screen user interface  5012  and a PiP user interface  5036  that continues to play a representation of the video. Automatically providing a representation of a currently playing video (e.g., a reduced-scale representation) while the device  100  navigates from a first application to a home screen enhances the operability of the device  100  by enabling a user to continue to watch the representation of the video while navigating to the home screen and thereafter, without requiring further user inputs. The method reduces the number, extent, and/or nature of the inputs from a user for providing a representation of a video while navigating between user interfaces, thereby creating a more efficient human-machine interface. 
     In some embodiments, in accordance with the determination that the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, the representation of the video is ( 6016 ) displayed at a location that is based on the characteristics of the contact at the end of the touch gesture. (e.g., based on at least one of the location of the contact at lift off and the velocity of the contact at lift off). For example, in FIGS.  5 A 31 - 5 A 32 , a termination of a contact  5048  occurs in an upper right corner of the touch screen  112 . In response, PiP user interface  5036  is displayed in the upper right corner of the touch screen  112 , as opposed to a bottom right corner of the touch screen  112  (which was the last location of the PiP user interface  5036 ). Displaying the representation of the video at a location based on the location and/or velocity of the contact at lift off allows the touch gesture to also position the representation of the video over the home screen user interface (in addition to navigating to the home screen user interface). Reducing the number of inputs needed to perform an operation enhances the operability of the device  100  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  100 ). 
     In some embodiments, in accordance with the determination that the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, the representation of the video is ( 6018 ) displayed at a predetermined location (e.g., at the last location, prior to detecting the touch gesture, where a representation of a video was shown over a user interface). For example, in FIG.  5 A 16 , a last location of the PiP user interface  5036  playing a representation of the video is in a bottom right corner of the touch screen  112 . Then, in FIGS.  5 A 17 - 5 A 20  and  5 A 23 - 5 A 25 , in response to an initiation and liftoff of a gesture by contact  5048  that is an upward swipe gesture from the edge of the touch screen  112 , the PiP user interface  5036  (shown in FIG.  5 A 25 ) is displayed in the same location as in FIG.  5 A 16 . In some embodiments, the representation of the video is displayed at a predetermined size (e.g., at the last size, prior to detecting the touch gesture, at which a representation of a video was shown over a user interface). For example, the PiP user interface  5036  of FIG.  5 A 25  is the same size as the PiP user interface  5036  in FIG.  5 A 16 . Displaying the representation of the video at a predetermined location (e.g., at the last location where a representation of a video was shown on the touch-sensitive display, which is optionally a location set by a user during prior use) allows the touch gesture to also position the representation of the video over the home screen user interface (in addition to navigating to the home screen user interface). Reducing the number of inputs needed to perform an operation enhances the operability of the device  100  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  100 ). 
     In some embodiments, in accordance with the determination that the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, the representation of the video is ( 6020 ) displayed overlaid on top of at least a portion of the home screen user interface (e.g., the representation of the video visually “floats” over the home screen user interface in a virtual z direction). For example, the PiP user interface  5036  and the PiP user interface  5036  in FIGS.  5 A 25  and  5 A 33 , respectively, are overlaid on the home screen user interface  112 . Displaying the representation of the video overlaid on top of the home screen user interface provides visual feedback that the representation of the video is separate from the home screen user interface. Providing improved feedback enhances the operability of the device  100  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  100 ). 
     In accordance with a determination that the touch gesture meets the first system navigation criteria and there is not video playing in the application when the touch gesture is detected, the device  100  displays ( 6022 ) the home screen user interface without displaying the representation of the video. For example, in FIG.  5 A 3 , a web browsing user interface  5002  is displayed without playing video and a gesture by contact  5006  is detected at an edge of the touch screen  112 . In FIGS.  5 A 4 - 5 A 6  and  5 A 8 , the gesture by contact  5006  is an upward swipe gesture that moves to an upper portion of the touch screen  112 . Because gesture by the contact  5006  originated at an edge of the touch screen  112  and the contact  5006  is an upward swipe gesture that moved a predetermine distance, system navigation criteria are met. However, because the video was not playing in the web browsing user interface  5002 , the device  100  displays the home screen user interface  5012  without displaying the representation of the video originally in the web browsing user interface  5002  (e.g., without displaying PiP user interface  5036  with its reduced-scale representation of the video). 
     In some embodiments, in response to detecting the touch gesture, in accordance with a determination that the touch gesture meets first system navigation criteria, there is video playing in the application when the touch gesture is detected, and the touch gesture meets video minimization criteria, the device  100  concurrently displays ( 6024 ) the home screen user interface and the representation of the video that is playing in the application, wherein the displayed representation of the video is a minimized representation of the video. For example, in FIGS.  5 A 17 - 5 A 20 ,  5 A 23 ,  5 A 30 - 5 A 31 , and  5 A 34 - 5 A 35 , a gesture by contact  5048  (shown in FIG.  5 A 17 ) representative of an upward swipe gesture is detected at the edge of the touch screen  112  while a video is playing in web browsing user interface  5002 . As shown in FIG.  5 A 23 , upon the contact  5048  moving a predetermined distance in a predetermined direction, system navigation criteria is met. As shown in FIG.  5 A 34 , upon the contact  5048  moving across a threshold of the touch screen  112 , video minimization criteria are met. In response, in FIG.  5 A 35 , the device  100  displays a home screen user interface  5012  and a minimized representation of the video  5058  that includes an expand affordance on the touch screen  112 . In some embodiments, the device  100  displays an animation in which a representation of the user interface for the application transitions to become the minimized representation of the video  5058  that is concurrently displayed with the home screen user interface. In some embodiments, the device  100  displays an animation in which the video in the user interface for the application transitions to become the minimized representation of the video  5058  that is concurrently displayed with the home screen user interface. In some embodiments, the video minimization criteria include a criterion that is met when the contact in the gesture is at an edge of the touch-sensitive display when the end of the gesture is detected. For example, in FIGS.  5 A 34 - 5 A 35 , upon the contact  5048  moving to an upper right edge of the touch screen  112 , the gesture ends with the contact lifting off at the upper right edge of the touch-sensitive display, which satisfies the video minimization criteria, and thereby causes the minimized representation of the video  5058  to be shown at the upper right edge of the touch-sensitive display, as shown in FIG.  5 A 35 . In some embodiments, an input on the minimized representation of the video (e.g., a drag gesture on the minimized representation of the video that moves away from an edge of the touch-sensitive display that is next to the minimized representation of the video, or a tap gesture on the minimized representation of the video) causes the minimized representation of the video to be replaced by a larger representation of the video, which includes a reduced scale representation of the video being played back. In some embodiments, the video minimization criteria include a criterion that is met when a velocity of the contact at lift off would (virtually) throw the representation of the video over an edge of the touch-sensitive display. In accordance with a determination that the touch gesture meets first system navigation criteria, there is video playing in the application when the touch gesture is detected, and the touch gesture does not meet the video minimization criteria, the device  100  concurrently displays the home screen user interface and the representation of the video that is playing in the application, wherein the displayed representation of the video is larger than the minimized representation of the video. For example, in FIGS.  5 A 17 - 5 A 20  and  5 A 23 - 5 A 25 , and  5 A 30 - 5 A 33 , a gesture by contact  5048  (shown in FIG.  5 A 17 ) representative of an upward swipe gesture is detected at the edge of the touch screen  112  while a video is playing in web browsing user interface  5002 . As shown in FIG.  5 A 23 , upon the contact  5048  moving a predetermined distance in a predetermined direction, system navigation criteria is met. As shown in FIG.  5 A 32 , upon liftoff of the contact  5048  away from the edge of the touch screen  112 , video minimization criteria are not met. In response, the device  100  displays a home screen user interface  5012  and a PiP user interface  5036  that is larger than the minimized representation of the video  5058  in FIG.  5 A 35 . In some embodiments, the device  100  displays an animation in which a representation of the user interface for the application transitions to become a non-minimized representation of the video that is concurrently displayed with the home screen user interface, where the non-minimized representation of the video includes a reduced scale representation of the video being played back that is larger than the minimized representation of the video. For example, in FIGS.  5 A 32 , PiP user interface  5036  (e.g., a non-minimized representation of the video) includes a reduced scale representation of the video being played back that is larger than the expand affordance  5058  (e.g., the minimized representation of the video). In some embodiments, the device  100  displays an animation in which the video in the user interface for the application transitions to become a non-minimized representation of the video that is concurrently displayed with the home screen user interface. For example, in FIGS.  5 A 32 - 5 A 33 , the gesture ends with the contact lifting off away from an edge of the touch-sensitive display, which does not satisfy the video minimization criteria, and thereby causes a non-minimized representation of the video  5036  (e.g., a reduced scale representation of the video being played back relative to the video played in the application user interface) to be shown on the touch-sensitive display. In some embodiments, an input on the non-minimized representation of the video (e.g., a drag gesture on the non-minimized representation of the video that moves the non-minimized representation of the video to an edge of the touch-sensitive display) causes the non-minimized representation of the video to be replaced by the minimized representation of the video. In some embodiments, the minimized representation of the video does not include a reduced scale representation of the video being played back. In some embodiments, the minimized representation of the video includes only a portion, less than all, of a reduced scale representation of the video being played back, such as a blurred portion of the video. In some embodiments, the minimized representation of the video includes a visual indicia (e.g., chevron  5058  in FIG.  5 A 35 ) that provides an indication that the minimized representation of the video is configured to be expanded (e.g., in response to detecting a drag or tap gesture on the visual indicia) to show more of the representation of the video, as illustrated in FIGS.  5 A 36 - 5 A 37 . 
     As explained above, in some embodiments, a gesture that is used to navigate to the home screen, to an application-switching user interface, or to a second application, depending on characteristics of the gesture (e.g., depending on the speed, direction, and/or location of the contact in the gesture at lift off) is also used to either (1) display and play a reduced scale representation of the video (which allows the user to continue to watch the video) or (2) display and play a minimized representation of the video. Using the same gesture for these two additional actions eliminates the need for additional inputs to either display and play the representation of the video or minimize and play the representation of the video. Reducing the number of inputs needed to perform an operation enhances the operability of the device  100  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  100 ). 
     In some embodiments, when the touch gesture meets first system navigation criteria and there is video playing in the application when the touch gesture is detected, in response to detecting an end of the touch gesture (e.g., in response to detecting lift off of the contact in the touch gesture), the device  100  displays ( 6026 ) (e.g., concurrently displaying): an animation of the representation of the video moving to a first location over the home screen user interface; and, an animation of an application icon that corresponds to the application moving (e.g., from a representation of the user interface for the application, such as a reduced-scale representation) to a second location in the home screen user interface (that is distinct from the first location over the home screen user interface). For example, in FIGS.  5 A 23 - 5 A 25 , upon liftoff of the contact  5048 , the PiP user interface  5036  transitions to the last displayed position of the PiP user interface  5036  at the bottom right corner of the touch screen  112 . Also upon liftoff of the contact  5048 , the web browsing card  5010  shrinks and travels towards the web browsing icon  5028  associated with the web browsing application. Displaying these two animations automatically positions the representation of the video over the home screen and provides visual feedback about which application icon corresponds to the representation of the video. Automatically positioning the representation of the video and providing improved feedback enhances the operability of the device  100  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). 
     In some embodiments, in response to detecting the touch gesture, in accordance with a determination that the touch gesture meets second system navigation criteria, the device  100  displays ( 6028 ) a system user interface that is distinct from the home screen user interface. In some embodiments, the representation of the video is concurrently displayed with the system user interface (e.g., FIGS.  5 A 20 ,  5 A 26 , and  5 A 27 ). In some embodiments, the system user interface is displayed without displaying the representation of the video (e.g., FIGS.  5 A 20 - 5 A 22 ). Displaying another system user interface (e.g., a system user interface configured for switching to another open application) in response to the touch gesture meeting different navigation criteria (e.g., detecting liftoff of a contact at a predetermined position on the touch screen  112 ) provides additional navigation options. For example, in FIG.  5 A 20 , as the contact  5048  moves towards a middle of the touch screen  112 , the threshold for displaying the application-switching user interface is met. In response, the web browsing card  5010  is displayed along with a search card  5014  in application switching user interface  5026 . In FIG.  5 A 21 , upon liftoff of the contact  5048 , the web browsing card  5010  becomes one of a number of cards (e.g., books card, maps card, calendar card and setting card) displayed within an application-switching user interface  5024 . Providing additional control options without cluttering the UI with additional displayed controls enhances the operability of the device  100  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). 
     In some embodiments, the system user interface is ( 6030 ) a user interface that is configured to select an open application to display from a plurality of recently used applications (e.g., without displaying any other open applications). In some embodiments, the representations of applications in this user interface include a view of content in the application from recent activity of the application (e.g., a snapshot or live view of a most recently used user interface of the application). For example, in FIG.  5 A 21 , upon liftoff of the contact  5048 , the web browsing card  5010  becomes one of a number of cards (e.g., books card, maps card, calendar card and setting card) displayed within an application-switching user interface  5024 . 
     In some embodiments, while concurrently displaying the system user interface and the representation of the video, the device  100  detects ( 6032 ) an input that selects a second application, distinct from the application that includes the video; and, in response to detecting the input that selects the second application, concurrently displaying the second application and the representation of the video (e.g., without displaying any other applications besides the second application). For example, in FIG.  5 A 27 , the application-switching user interface  5024  is displayed in the background and the PiP user interface  5036  is displayed at the bottom right corner of the touch screen  112 . The video continues to play in the PiP user interface  5036 . A gesture by contact  5050  (e.g., a tap gesture) is detected at a calendar card  5020 . In FIG.  5 A 28 , in response to detecting the contact  5050 , a calendar user interface  5054  is displayed on the touch screen  112 . In FIGS.  5 A 28 - 5 A 29 , the PiP user interface  5036  remains displayed at the bottom right corner of the touch screen  112  and the video continues to play in the PiP user interface  5036 . In some embodiments, the representation of the video is persistently displayed over the user interface that is configured to select a second application (e.g., an application-switching user interface  5026  of FIG.  5 A 20  or an application-switching user interface  5024  of FIG.  5 A 27 ) and also over the user interface of the second application (e.g., calendar user interface  5054 ). In some embodiments, the representation of the video is persistently displayed over the user interface that is configured to select a second application (e.g., an application-switching user interface  5026  of FIG.  5 A 20  or an application-switching user interface  5024  of FIG.  5 A 27 ), over the user interface of the second application, and over the home screen user interface (e.g., home screen user interface  5012  of FIGS.  5 A 23 - 5 A 25 ) as the device  100  navigates among these different user interfaces. Automatically providing a representation of a currently playing video (e.g., a reduced-scale representation) while the device  100  navigates from a first application to a home screen, to an application-switching user interface, and then to a second application enhances the operability of the device  100  by enabling a user to continue to watch the representation of the video while navigating elsewhere, without requiring further user inputs. The method reduces the number, extent, and/or nature of the inputs from a user for providing a representation of a video while navigating between user interfaces, thereby creating a more efficient human-machine interface. 
     In some embodiments, in response to detecting the touch gesture, in accordance with a determination that the touch gesture meets application operation criteria (e.g., wherein the application operation criteria include a requirement that the touch gesture is detected away from a respective edge of the device  100  in order for the application operation criteria to be met), the device  100  performs ( 6034 ) an operation within the application (e.g., if a swipe gesture starts away from the edge of the display, the device  100  scrolls content in the user interface of the application, as shown in FIGS.  5 A 1 - 5 A 2 ). Performing an operation within the application (e.g., scrolling the user interface of the application) in response to the touch gesture meeting different criteria provides additional control options. Providing additional control options without cluttering the UI with additional displayed controls enhances the operability of the device  100  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  100 ). 
     It should be understood that the particular order in which the operations in  FIGS.  6 A- 6 C  have been described is merely one example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. 
     The operations described above with reference to  FIGS.  6 A- 6 C  are, optionally, implemented by components depicted in  FIGS.  1 A- 1 B . For example, detecting operation  6004  and/or operation  6034  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device  100 ) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device  100  from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS.  1 A- 1 B . 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best use the invention and various described embodiments with various modifications as are suited to the particular use contemplated.
