CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from U.S. Provisional Ser. No. 62/172,173, entitled “VIDEO RECORDING AND REPLAY,” filed Jun. 7, 2015, which is hereby incorporated by reference in its entirety for all purposes. 
    
    
     FIELD 
     The present disclosure relates generally to computer user interfaces, and more specifically to techniques for recording and playing audio and video. 
     BACKGROUND 
     The use of electronic devices for game play, productivity, and multimedia has increased significantly in recent years. Electronic devices can also be used to record audio and video using a microphone and a camera sensor. Electronic devices can also play back the recorded audio and video. 
     BRIEF SUMMARY 
     Some techniques for recording and playing audio and video using electronic devices, however, are generally cumbersome and inefficient. For example, existing techniques use a complex and time-consuming user interface, which may include multiple key presses or keystrokes. Existing techniques require more time than necessary, wasting user time and device energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, the present disclosure provides for electronic devices with faster, more efficient methods and interfaces for recording and playing audio and video. Such methods and interfaces optionally complement or replace other methods for recording and playing video. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges. Such methods and interfaces also reduce processing power, reduce memory usage, reduce battery usage by a display, reduce receiving unnecessary, extraneous, or repetitive inputs.

     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for recording and playing audio and video. Such techniques can reduce the cognitive burden on a user who access event notifications, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs.

FIG. 9  is a flow diagram illustrating methods of recording and playing audio and video in accordance with some embodiments. The user interfaces in  FIGS. 8A-8I  are used to illustrate the processes described below, including the processes in  FIG. 9 . 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device may support a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG. 1A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  may include one or more computer-readable storage mediums. The computer-readable storage mediums may be tangible and non-transitory. Memory  102  may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  may control access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  may be implemented on a single chip, such as chip  104 . In some other embodiments, they may be implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry  108  optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. The wireless communication optionally uses any of a plurality of communications standards, protocols, and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data may be retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG. 2 ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input control devices  116 . The other input control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  are, optionally, coupled to any (or none) of the following: a keyboard, an infrared port, a USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG. 2 ). 
     A quick press of the push button may disengage a lock of touch screen  112  or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) may turn power to device  100  on or off. The user may be able to customize a functionality of one or more of the buttons. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen  112  and display controller  156  may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of touch screen  112  may be analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  may also include one or more optical sensors  164 .  FIG. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  may capture still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image may be obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  may be used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  may also include one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  may be coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  may also include one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  may be coupled to an input controller  160  in I/O subsystem  106 . Accelerometer  168  may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         Contacts module  137  (sometimes called an address book or contact list);   Telephone module  138 ;   Video conference module  139 ;   E-mail client module  140 ;   Instant messaging (IM) module  141 ;   Workout support module  142 ;   Camera module  143  for still and/or video images;   Image management module  144 ;   Video player module;   Music player module;   Browser module  147 ;   Calendar module  148 ;   Widget modules  149 , which may include one or more of: weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   Widget creator module  150  for making user-created widgets  149 - 6 ;   Search module  151 ;   Video and music player module  152 , which merges video player module and music player module;   Notes module  153 ;   Map module  154 ; and/or   Online video module  155 .

No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. For example, video player module may be combined with music player module into a single module (e.g., video and music player module  152 ,  FIG. 1A ). In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store 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  may be reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG. 1B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may 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 may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  may utilize or call data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which may 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 may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers may interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG. 3  is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG. 1A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG. 1A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG. 1A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG. 1A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG. 3  may be stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  may store a subset of the modules and data structures identified above. Furthermore, memory  370  may store additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that may be implemented on, for example, portable multifunction device  100 . 
       FIG. 4A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces may be implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, icon  422  for video and music player module  152  may optionally be labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG. 3 ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG. 3 ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  357 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
     Although some of the examples which follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 460  corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG. 5A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS. 1A-4B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) may have one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Techniques for detecting and processing touch intensity may be found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms may permit device  500  to be worn by a user. 
       FIG. 5B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS. 1A, 1B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, touch-intensity sensitive component  524 . In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  may be a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  may be a button, in some examples. 
     Input mechanism  508  may be a microphone, in some examples. Personal electronic device  500  can include various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can be a non-transitory computer-readable storage medium, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described above, including processes  700  and  900 . The computer-executable instructions can also be stored and/or transported within any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. For purposes of this document, a “non-transitory computer-readable storage medium” can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG. 5B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that may be displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS. 1, 3, and 5 ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) may each constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG. 3  or touch-sensitive surface  451  in  FIG. 4B ) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG. 1A  or touch screen  112  in  FIG. 4A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds 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 threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location 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 intensity of a contact on the touch-sensitive surface may be characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are optionally implemented on an electronic device with a display, such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS. 6A-6E  illustrate exemplary user interfaces for recording data streams, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 7 . 
     At  FIG. 6A , the electronic device displays, on the display, a user interface (e.g.,  602 ) for a first application (e.g., a game application; a workout application for an outdoor work out such as a run or bike ride or an indoor workout). In this example, the device displays a tennis game application. In some embodiments, for security reasons, the first application (e.g., the game application) is restricted from accessing or recording one or more types of data streams associated with user activity while using the device (e.g., the first application is prohibited from generating screen recordings and/or recording user activity via a camera or microphone of the device). 
     The electronic device detects a record request (e.g., via an API call based on activation of record affordance  604 ) from the first application (e.g., the game application) to a second application (e.g., an operating system of the electronic device or another application on the electronic device that has privileges to record data streams associated with user activity while using the device that the first application is prohibited from recording). The record request corresponds to a request for the second application to initiate recording of one or more data streams that include at least one data stream generated by the first application (or channels; such as an application video channel of the first application, an application audio channel of the first application, an audio input channel received at a microphone of the electronic device, a video input channel received at a camera sensor of the electronic device). In some examples, at least one of the data streams is associated with the first application (e.g., one of the data streams is a data stream of video or audio output by the first application). 
     At  FIG. 6B , in response to detecting the record request from the first application (e.g., to the second application), the electronic device displays, on the display, a user interface ( 608 ) for the second application, the user interface ( 608 ) for the second application including a confirmation affordance ( 612 ). For example, the device requests user confirmation that it is acceptable to allow the electronic device to record game play (e.g., audio/video data streams of the game), audio received at a microphone of the electronic device, and a video received at a camera sensor (e.g.,  164 ) of the electronic device. In the example of  FIG. 6B , prior to (and, optionally, concurrent with) detecting the record request, the electronic device displays an indication  606  of the one or more data streams to be requested for recording. 
     At  FIG. 6B , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the confirmation affordance ( 612 ). In response to detecting activation of the confirmation affordance (e.g.,  612 ), the electronic device initiates (e.g., by the second application) a recording of at least one data stream of the one or more data streams. Alternatively, if the device detects (e.g., by the second application) activation (e.g., by the user) of a decline affordance ( 614 ), the electronic device forgoes initiating the recording of at least one data stream of the one or more data streams. In the example of  FIG. 6B , the electronic device concurrently displays an indication ( 610 ) of the one or more data streams to be requested for recording with the confirmation affordance ( 612 ). 
     As illustrated in  FIG. 6C , the first application (the game application) displays graphical elements and provides output audio. As described in more detail below, in  FIG. 6C , the electronic device displays stop affordance  616  and picture-in-picture video  618  of the video received at the camera sensor of the device. 
     The electronic device detects a stop request (e.g., via an API call) requesting stoppage of recording (e.g., based on user activation of stop affordance  616  or end of a game level) of the at least one data stream of the one or more data streams. For example, the first application initiates the stop request and the stop request is received by the second application (e.g., the operating system of the electronic device). 
     In  FIG. 6D , in response to detecting the stop request, the electronic device stops (e.g., by the second application) recording of the at least one data stream of the one or more data streams. In  FIG. 6D , as described in detail below, in response to detecting the stop request, the electronic device displays, on the display, a second user interface  620  of the second application. 
     In some embodiments, the first application (e.g., game application) initiates the record request in response to a user input (e.g., detecting activation of a record affordance  606  of the first application; detecting activation of a level-start affordance that starts a game level, such as by selecting a button that is associated with text indicating that video will be recorded such as “play level with recording” instead of selecting a button that is not associated with text indicating that video will be recorded, such as “play level”). 
     In some embodiments, the record request specifies a request for recording audio data and video data of the first application (e.g., video displayed on the display of the device and audio output by the device). 
     In some embodiments, the record request specifies a request for recording event information of the first application. The electronic device receives a playback request. In response to receiving the playback request, the electronic device reproduces the audio and video of the first application based on the event information of the first application. For example, the event information enables the game application to recreate a playthrough of a game from multiple different angles, rather than merely playing back sounds and images generated by the game during the playthrough). For example, the event information includes the location of an animated game player within a scene of the game. 
     In some embodiments, the electronic device includes a microphone. The record request specifies a request for recording audio data and video data of the first application and audio data received at the microphone of the device. For example, the electronic device records audio/video of the first application and sounds made by the user during the game play (e.g., the user yelling or explaining why he is taking actions within the game). 
     In some embodiments, the electronic device includes a microphone and a camera sensor. The record request specifies a request for recording audio data and video data of the first application, audio received at the microphone of the device, and video received at the camera sensor of the device. For example, the electronic device records audio/video of the first application and sounds made by the user during the game play (e.g., the user yelling or explaining why he is taking actions within the game), and facial expressions of the user during the game play. 
     In some embodiments, while recording, the electronic device displays, on the display, a picture-in-picture video (e.g.,  618 ) of the video received at the camera sensor of the device. For example, the device records the video received at the camera sensor as a data stream. For example, the video received at the camera sensor captures the user&#39;s reactions (e.g., facial expressions) as the user is playing the game. The device also displays the video received at the camera sensor during the recording (e.g., live or near-live) to allow the user to see the camera&#39;s field of view (e.g., what is being recorded). 
     In some embodiments, initiating the recording of the at least one data stream of the one or more data streams includes storing each data stream of the at least one data stream separately in memory (e.g., so that the some (or all) data streams can be combined or not combined at a later time to create a multimedia file). 
     In some embodiments, initiating the recording of the at least one data stream of the one or more data streams includes storing, to memory, synchronization data to synchronize playback of the at least one data stream (e.g., so that the data streams can be synchronized at a later time such that the audio/video of the first application are in sync with any recorded audio from the microphone and any recorded video from the camera sensor). 
     In some embodiments, the user interface (e.g.,  608 ) for the second application further includes a visual indicator (e.g.,  610 ) indicating the at least one data stream of the one or more data streams requested to be recorded. For example, the second application includes an indication asking “Allow recording of: game play and your audio and video?” or an indication that “The audio/video of the game and your voice will be recorded.” 
     In some embodiments, the electronic device stores the recording of the at least one data stream of the one or more data streams into a memory of the device (e.g., from the record time to the stoppage time). The first application does not have access to the stored recording of the at least one data stream of the one or more data streams. This provides additional security, as the first application does not have access to the recorded content without additional user confirmation. For example, the electronic device receives user confirmation to provide the first application access to the recorded at least one data stream of the one or more data streams. In response to receiving the user confirmation, the electronic device (e.g., via the second application) provides the first application with access to the recorded at least one data stream of the one or more data streams. 
     In some embodiments, the first application is a game. In response to initiating the recording of the at least one data stream of the one or more data streams, the electronic device receives by the first application a confirmation (e.g., from the second application) that recording has started. In response to receiving the confirmation that recording has started, the electronic device initiates a game play (e.g., starts a level of the game) of the first application. 
     In some embodiments, the user interface (e.g.,  602 ) for the first application includes one or more visual objects (e.g., displayed affordances  616  or displayed timers “0:06”) that are not recorded as part of the at least one data stream of the one or more data streams. The at least one data stream of the one or more data steams includes a video stream of the first application (e.g., of the displayed user interface  602 ). For example, the first application displays a pause affordance, a stop affordance (e.g.,  616 ), an add bookmarkers affordance, and/or a timer (e.g., 0:06) indicating the duration of a current recording that is not recorded or stored in memory as part of the recording of the audio/video of the first application. 
     In some embodiments, in response to detecting the stop request, the electronic device displays, on the display, a second user interface (e.g.,  620 ) of the second application. The second user interface (e.g.,  620 ) of the second application provides an option (e.g.,  624 ) for sharing (e.g., by email, by text message, via a social network) the recorded at least one data stream of the one or more data streams. For example, activating the option (e.g.,  624 ) for sharing causes the electronic device to transmit the recorded at least one data stream of the one or more data streams to a remote server, provide an option to transmit the recorded at least one data stream of the one or more data streams, or provide the first application (or another application) with access to the recorded at least one data stream of the one or more data streams. 
     In some embodiments, in response to detecting the stop request, the electronic device displays, on the display, a second user interface (e.g.,  620 ) of the second application. The second user interface (e.g.,  620 ) of the second application provides one or more options to edit (e.g.,  622 ) or playback (e.g.,  630 ) the recorded at least one data stream of the one or more data streams. For example, the second user interface (e.g.,  620 ) allows one or more of the following: discarding (e.g., via affordance  626 ) recorded streams; playing back (e.g., via playback affordance  630 ) of recorded streams (individually, a subset, or together), storing to memory (e.g., via affordance  628 ) trimming (e.g., via affordance  622 ) of recorded streams, adding voiceover (using a microphone of the device) to recorded streams, adding picture-in-picture video (using a camera sensor of the device) to recorded streams, overlaying indications of measured galvanic skin response data to recorded streams, overlaying indications of measured heart rate data to recorded streams, enabling and disabling of visual or audio indications corresponding to touch information from a touch-sensitive surface captured during the recording, or combining portions of different streams during different times of the recording (e.g., turn on video picture-in-picture for a portion of the recording) using individual recorded data streams. 
     As illustrated in  FIG. 6E , in some embodiments, the device detects activation of playback affordance  630 . In response to detecting activation of playback affordance  630 , the electronic device displays playback user interface  640 . Playback user interface  640  includes an option to share (e.g., via affordance  624 ) the audio/video being played back. In some examples, the audio/video being played back includes combinations of data streams, such as picture-in-picture video  642  of the video received at the camera sensor of the device during game play and heart rate information  644  detected by a second electronic device, as described below. 
     In some embodiments, the one or more data streams include a remote data stream received from a second electronic device different from the first electronic device. For example, the electronic device receives heart rate information detected by a paired smartwatch or recorded video information received from a camera sensor of a connected smartphone. In some examples, as illustrated in  FIG. 6E , information based on the remote data stream received from the second electronic device is available for display. For example, the remote data stream is synchronized in time with the other data streams. In this example, heart rate information  644  is displayed concurrently with the playback of audio/video of the second application, allowing a user of the device to correlate the user&#39;s heart rate with a portion of the game. 
     In some embodiments, the electronic device stores a temporal marker (or a plurality of temporal markers). The temporal marker (or each temporal marker of the plurality of temporal markers) is associated with a time of at least one of the one or more data streams. The temporal marker is based on information received from the first application (e.g., the game). The temporal marker allows marking at location of the data stream that is not at the beginning or end of the data stream (e.g., a midpoint). For example, the second application creates markers based on information from the second application (e.g., times when achievements were unlocked, laps were completed, levels began or ended, etc.) to allow the user to subsequently quickly access, review, or those marked portions of the recording. 
     In some embodiments, the electronic device generates a highlight data stream (e.g., audio/video multimedia file) based on the temporal marker (or plurality of temporal markers) and based on a portion (e.g., but not all) of the at least one data stream of the one or more data streams. For example, the electronic device puts together a highlight video. In some embodiments, the portions of the at least one data stream of the one or more data streams included in the highlight video are based on measured galvanic skin response data collected during the recording or heart rate data measured during the recording. In some embodiments, if the electronic device determines that a user has opted-in, the electronic device indexes recordings at different points in a game using predefined markers and uploads the videos to one or more servers. The electronic device then enables users to search for uploaded videos that include a requested marker so that users can find and view the videos. This allows users to quickly find videos that they can watch to see how other players have played a particular level or aspect of a game, such has how players have solved a puzzle in a game. 
       FIG. 7  is a flow diagram illustrating a method for recording data streams using an electronic device in accordance with some embodiments. Method  700  is performed at a device (e.g.,  100 ,  300 ,  500 ) with a display. Some operations in method  700  may be combined, the order of some operations may be changed, and some operations may be omitted. 
     As described below, method  700  provides an intuitive way for recording data streams. The method reduces the cognitive burden on a user for recording data streams, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to recording data streams faster and more efficiently conserves power and increases the time between battery charges. 
     At block  702 , the electronic device displays, on the display, a user interface (e.g.,  602 ) for a first application (e.g., a game application; a workout application for an outdoor work out such as a run or bike ride or an indoor workout). For example, the device displays a tennis game application. In some embodiments, for security reasons, the first application (e.g., the game application) is restricted from accessing or recording one or more types of data streams associated with user activity while using the device (e.g., the first application is prohibited from generating screen recordings and/or recording user activity via a camera or microphone of the device). 
     At block  704 , the electronic device detects a record request (e.g., via an API call based on activation of record affordance  604 ) from the first application (e.g., the game application) to a second application (e.g., an operating system of the electronic device or another application on the electronic device that has privileges to record data streams associated with user activity while using the device that the first application is prohibited from recording). The record request corresponds to a request for the second application to initiate recording of one or more data streams that include at least one data stream generated by the first application (or channels; such as an application video channel of the first application, an application audio channel of the first application, an audio input channel received at a microphone of the electronic device, a video input channel received at a camera sensor of the electronic device). In some examples, at least one of the data streams is associated with the first application (e.g., one of the data streams is a data stream of video or audio output by the first application). 
     At block  706 , in response to detecting the record request from the first application (e.g., to the second application), the electronic device displays, on the display, a user interface (e.g.,  608 ) for the second application, the user interface (e.g.,  608 ) for the second application including a confirmation affordance (e.g.,  612 ). For example, the device requests user confirmation that it is acceptable to allow the electronic device to record game play (e.g., audio/video data streams of the game), audio received at a microphone of the electronic device, and a video received at a camera sensor (e.g.,  164 ) of the electronic device. In some examples, prior to (and, optionally, concurrent with) detecting the record request, the electronic device displays an indication  606  of the one or more data streams to be requested for recording. 
     At block  708 , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the confirmation affordance (e.g.,  612 ). 
     At block  710 , in response to detecting activation of the confirmation affordance (e.g.,  612 ), the electronic device initiates (e.g., by the second application) a recording of at least one data stream of the one or more data streams. Alternatively, if the device detects (e.g., by the second application) activation (e.g., by the user) of a decline affordance (e.g.,  614 ), the electronic device forgoes initiating the recording of at least one data stream of the one or more data streams. In some examples, the electronic device concurrently displays an indication (e.g.,  610 ) of the one or more data streams to be requested for recording with the confirmation affordance (e.g.,  612 ). 
     At block  712 , the electronic device detects a stop request (e.g., via an API call) requesting stoppage of recording (e.g., based on user activation of stop affordance  616  or end of a game level) of the at least one data stream of the one or more data streams. For example, the first application initiates the stop request and the stop request is received by the second application (e.g., the operating system of the electronic device). 
     At block  714 , in response to detecting the stop request, the electronic device stops (e.g., by the second application) recording of the at least one data stream of the one or more data streams. 
     In some embodiments, the first application (e.g., game application) initiates the record request in response to a user input (e.g., detecting activation of a record affordance  606  of the first application; detecting activation of a level-start affordance that starts a game level, such as by selecting a button that is associated with text indicating that video will be recorded such as “play level with recording” instead of selecting a button that is not associated with text indicating that video will be recorded, such as “play level”). 
     In some embodiments, the record request specifies a request for recording audio data and video data of the first application (e.g., video displayed on the display of the device and audio output by the device). 
     In some embodiments, the record request specifies a request for recording event information of the first application. The electronic device receives a playback request. In response to receiving the playback request, the electronic device reproduces the audio and video of the first application based on the event information of the first application. For example, the event information enables the game application to recreate a playthrough of a game from multiple different angles, rather than merely playing back sounds and images generated by the game during the playthrough). For example, the event information includes the location of an animated game player within a scene of the game. 
     In some embodiments, the electronic device includes a microphone. The record request specifies a request for recording audio data and video data of the first application and audio data received at the microphone of the device. For example, the electronic device records audio/video of the first application and sounds made by the user during the game play (e.g., the user yelling or explaining why he is taking actions within the game). 
     In some embodiments, the electronic device includes a microphone and a camera sensor. The record request specifies a request for recording audio data and video data of the first application, audio received at the microphone of the device, and video received at the camera sensor of the device. For example, the electronic device records audio/video of the first application and sounds made by the user during the game play (e.g., the user yelling or explaining why he is taking actions within the game), and facial expressions of the user during the game play. 
     In some embodiments, while recording, the electronic device displays, on the display, a picture-in-picture video (e.g.,  618 ) of the video received at the camera sensor of the device. For example, the device records the video received at the camera sensor as a data stream. For example, the video received at the camera sensor captures the user&#39;s reactions (e.g., facial expressions) as the user is playing the game. The device also displays the video received at the camera sensor during the recording (e.g., live or near-live) to allow the user to see the camera&#39;s field of view (e.g., what is being recorded). 
     In some embodiments, initiating the recording of the at least one data stream of the one or more data streams includes storing each data stream of the at least one data stream separately in memory (e.g., so that the some (or all) data streams can be combined or not combined at a later time to create a multimedia file). 
     In some embodiments, initiating the recording of the at least one data stream of the one or more data streams includes storing, to memory, synchronization data to synchronize playback of the at least one data stream (e.g., so that the data streams can be synchronized at a later time such that the audio/video of the first application are in sync with any recorded audio from the microphone and any recorded video from the camera sensor). 
     In some embodiments, the user interface (e.g.,  608 ) for the second application further includes a visual indicator (e.g.,  610 ) indicating the at least one data stream of the one or more data streams requested to be recorded. For example, the second application includes an indication asking “Allow recording of: game play and your audio and video?” or an indication that “The audio/video of the game and your voice will be recorded.” 
     In some embodiments, the electronic device stores the recording of the at least one data stream of the one or more data streams into a memory of the device (e.g., from the record time to the stoppage time). The first application does not have access to the stored recording of the at least one data stream of the one or more data streams. This provides additional security, as the first application does not have access to the recorded content without additional user confirmation. For example, the electronic device receives user confirmation to provide the first application access to the recorded at least one data stream of the one or more data streams. In response to receiving the user confirmation, the electronic device (e.g., via the second application) provides the first application with access to the recorded at least one data stream of the one or more data streams. 
     In some embodiments, the first application is a game. In response to initiating the recording of the at least one data stream of the one or more data streams, the electronic device receives by the first application a confirmation (e.g., from the second application) that recording has started. In response to receiving the confirmation that recording has started, the electronic device initiates a game play (e.g., starts a level of the game) of the first application. 
     In some embodiments, the user interface (e.g.,  602 ) for the first application includes one or more visual objects (e.g., displayed affordances  616  or displayed timers “0:06”) that are not recorded as part of the at least one data stream of the one or more data streams. The at least one data stream of the one or more data steams includes a video stream of the first application (e.g., of the displayed user interface  602 ). For example, the first application displays a pause affordance, a stop affordance (e.g.,  616 ), an add bookmarkers affordance, and/or a timer (e.g., 0:06) indicating the duration of a current recording that is not recorded or stored in memory as part of the recording of the audio/video of the first application. 
     In some embodiments, in response to detecting the stop request, the electronic device displays, on the display, a second user interface (e.g.,  620 ) of the second application. The second user interface (e.g.,  620 ) of the second application provides an option (e.g.,  624 ) for sharing (e.g., by email, by text message, via a social network) the recorded at least one data stream of the one or more data streams. For example, activating the option (e.g.,  624 ) for sharing causes the electronic device to transmit the recorded at least one data stream of the one or more data streams to a remote server, provide an option to transmit the recorded at least one data stream of the one or more data streams, or provide the first application with access to the recorded at least one data stream of the one or more data streams. 
     In some embodiments, in response to detecting the stop request, the electronic device displays, on the display, a second user interface (e.g.,  620 ) of the second application. The second user interface (e.g.,  20 ) of the second application provides one or more options to edit (e.g.,  622 ) or playback (e.g.,  630 ) the recorded at least one data stream of the one or more data streams. For example, the second user interface (e.g.,  620 ) allows one or more of the following: discarding (e.g., via affordance  626 ) recorded streams; playing back (e.g., via playback affordance  630 ) of recorded streams (individually, a subset, or together), storing to memory (e.g., via affordance  628 ) trimming (e.g., via affordance  622 ) of recorded streams, adding voiceover (using a microphone of the device) to recorded streams, adding picture-in-picture video (using a camera sensor of the device) to recorded streams, overlaying indications of measured galvanic skin response data to recorded streams, overlaying indications of measured heart rate data to recorded streams, enabling and disabling of visual or audio indications corresponding to touch information from a touch-sensitive surface captured during the recording, or combining portions of different streams during different times of the recording (e.g., turn on video picture-in-picture for a portion of the recording) using individual recorded data streams. 
     In some embodiments, the device detects activation of playback affordance (e.g.,  630 ). In response to detecting activation of playback affordance (e.g.,  630 ), the electronic device displays playback user interface (e.g.,  640 ). Playback user interface (e.g.,  640 ) includes an option to share (e.g., via affordance  624 ) the audio/video being played back. In some examples, the audio/video being played back includes combinations of data streams, such as picture-in-picture video (e.g.,  642 ) of the video received at the camera sensor of the device during game play and heart rate information (e.g.,  644 ) detected by a second electronic device, as described below. 
     In some embodiments, the one or more data streams include a remote data stream received from a second electronic device different from the first electronic device. For example, the electronic device receives heart rate information detected by a paired smartwatch or recorded video information received from a camera sensor of a connected smartphone. In some examples, information based on the remote data stream received from the second electronic device is available for display. For example, the remote data stream is synchronized in time with the other data streams. For example, heart rate information (e.g.,  644 ) is displayed concurrently with the playback of audio/video of the second application, allowing a user of the device to correlate the user&#39;s heart rate with a portion of the game. 
     In some embodiments, the electronic device stores a temporal marker (or a plurality of temporal markers). The temporal marker (or each temporal marker of the plurality of temporal markers) is associated with a time of at least one of the one or more data streams. The temporal marker is based on information received from the first application (e.g., the game). The temporal marker allows marking at location of the data stream that is not at the beginning or end of the data stream. For example, the second application creates markers based on information from the second application (e.g., times when achievements were unlocked, laps were completed, levels began or ended, etc.) to allow the user to subsequently quickly access, review, or those marked portions of the recording. 
     In some embodiments, the electronic device generates a highlight data stream (e.g., audio/video multimedia file) based on the temporal marker (or plurality of temporal markers) and based on a portion (e.g., but not all) of the at least one data stream of the one or more data streams. For example, the electronic device puts together a highlight video. In some embodiments, the portions of the at least one data stream of the one or more data streams included in the highlight video are based on measured galvanic skin response data collected during the recording or heart rate data measured during the recording. In some embodiments, the electronic device determines that a user has opted-in, the electronic device indexes recordings at different points in a game using predefined markers and uploads the videos to one or more servers. The electronic device then enables users to search for uploaded videos that include a requested marker so that users can find and view the videos. This allows users to quickly find videos that they can watch to see how other players have played a particular level or aspect of a game, such has how players have solved a puzzle in a game. 
     Note that details of the processes described above with respect to method  700  (e.g.,  FIG. 7 ) are also applicable in an analogous manner to the methods described below. For example, method  900  optionally includes one or more of the characteristics of the various methods described above with reference to method  700 . For example, the data streams, affordances, and applications of method  900  optionally have one or more of the characteristics of the data streams, affordances, and applications of method  700 . For brevity, these details are not repeated below. 
       FIGS. 8A-8I  illustrate exemplary user interfaces for recording data streams, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 9 . 
     At  FIG. 8A , in some embodiments, the electronic device displays a user interface (e.g.,  802 ) for a first application (e.g., a game application). At  FIG. 8B , the electronic device concurrently displays, on the display, the user interface (e.g.,  802 ) for a first application (e.g., a game application, a workout application for an outdoor work out such as a run or bike ride or an indoor workout) and a user interface (e.g.,  804 A;  804 B; a control user interface without a recording affordance; a control user interface with a recording affordance; a recording affordance  810 ) for a second application (e.g., an operating system of the electronic device or another application on the electronic device that has privileges to record data streams associated with user activity while using the device that the first application is prohibited from recording). At least a portion of the user interface (e.g.,  804 A;  804 B;  810 ) for the first application is overlaid by at least a portion of the user interface for the second application. The user interface (e.g.,  804 A;  804 B;  810 ) for the second application includes a record affordance (e.g., which is part of the at least a portion of the user interface for the second application). 
     In some embodiments, as illustrated in  FIG. 8B  and as described in detail below, a first control user interface  804 A for the second application does not include a record user interface. As illustrated in  FIG. 8C , the device detects a swipe input (e.g., horizontal) associated with user interface  804 A. As illustrated in  FIG. 8D , in response to detecting the swipe input, the electronic device displays user interface  804 B, which includes record affordance  810 . 
     As illustrated in  FIG. 8E , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the record affordance (e.g.,  810 ). 
     As illustrated in  FIG. 8F , in response to detecting activation of the record affordance (e.g.,  810 ), the electronic device initiates (e.g., by the second application) a recording of at least one data stream of one or more data streams. In some examples, the at least one of the data streams includes a data stream associated with the first application (e.g., the video or audio output of the first application). For example, the electronic device displays an indication (e.g.,  818 ) that indicates that the electronic device is recording one or more data streams. 
     As illustrated in  FIG. 8G , the electronic device displays, on the user interface for the second application, a stop affordance (e.g., control user interface with stop affordance  832 ; a standalone stop affordance). In some examples, the stop affordance is displayed in response to detecting a vertical swipe. 
     As illustrated in  FIG. 8H , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the stop affordance (e.g.,  832 ). In response to detecting activation of the stop affordance, the electronic device stops recording of the at least one data stream of the one or more data streams. 
     In some embodiments, the electronic device includes a touch-sensitive surface. As illustrated in  FIG. 8B , prior to concurrently displaying, on the display, the user interface for the first application and the user interface for the second application, the electronic device receives a first swipe input in a first direction (e.g., up direction) at the touch-sensitive surface. In response to receiving the swipe input, the electronic device displays a control user interface (e.g.,  804 A) for the second application. The control user interface does not include the record affordance. As illustrated in  FIG. 8C , while displaying the control user interface (e.g.,  804 A) for the second application, the electronic device receives a second swipe input in a second direction (e.g., left direction) at the touch-sensitive surface (e.g., at a location corresponding to the control user interface (e.g.,  804 A). The record affordance (e.g.,  810 ) of the user interface for the second application is displayed as part of the control user interface (e.g.,  804 B) in response to receiving the second swipe input. 
     In some embodiments, prior to concurrently displaying, on the display, the user interface (e.g.,  802 ) for the first application and the user interface (e.g.,  804 B) for the second application, the electronic device receives a request to display controls for controlling functions of the second application (e.g., a request to display user interface  804 A). In response to receiving the request to display the control user interface (e.g.,  804 A,  804 B), the electronic device displays a control user interface that includes one or more controls (e.g.,  834 A,  834 B; for controlling functions of the second application. In some embodiments, the control user interface is displayed concurrently with at least a portion of the user interface of the first application. In some embodiments, the control user interface is displayed as a semi-transparent or transparent overlay on top of at least a portion of the user interface of the first application. In some embodiments, the control user interface includes other options for controlling functions of the device that are managed by the second application, such as volume (e.g., by  834 B), the on/off status of wireless antennas (e.g., by  834 C), media playback, etc. While the control user interface (e.g.,  804 A,  804 B) is displayed, the electronic device displays the record affordance  810  as part of the control user interface (e.g.,  804 B). 
     In some embodiments, in response to detecting activation of the record affordance (e.g.,  810 ), the electronic device updates the display to not include the record affordance (e.g.,  810 ). For example, the record affordance is replaced with the stop affordance. For another example, in response to detecting activation of the record affordance (e.g.,  810 ), the control user interface (e.g.,  804 A,  804 B including the user interface for the second application) slides away (e.g., down) and off the display. In some embodiments, when the control user interface slides away, a tongue (e.g.,  812 ; a handle) for the control user interface starts (or continues) to be displayed (e.g., overlaid on top of the user interface of the first application). The tongue (e.g.,  812 ) indicates that recording is in progress. In some examples, the tongue (e.g.,  812 ) also includes a displayed record time. 
     In some embodiments, the control user interface (e.g.,  804 A,  804 B) includes a record affordance (e.g.,  810 ) that is controlled by the second application (e.g., the operating system) and is overlaid on top of the user interface (e.g.,  802 ) for the first application (e.g., the game). In some embodiments, the record button (e.g.,  810 ) is displayed without displaying the control user interface. 
     In some embodiments, updating the display to not include the record affordance (e.g.,  810 ) includes replacing the record affordance with the stop affordance (e.g.,  832 ). 
     In some embodiments, the at least the portion of the user interface (e.g.,  804 B,  832 ) for the second application is not recorded as part of the at least one data stream of the one or more data streams. For example, the controls and timers of the second application are not part of the record streams. 
     In some embodiments, the second application provides an option (e.g., affordance  806 ) for recording audio data and video data of the first application (e.g., audio/video displayed/played on the device). 
     In some embodiments, the second application provides an option (e.g.,  806 ,  808 ,  810 ) for recording event information of the first application that can be used to reproduce audio and video of the first application (e.g., data enabling the game recreate a playthrough of a game from multiple different angles rather than just recording the audio/video generated by the game during the playthrough). For example, the device receives a playback request, and in response to receiving the playback request, the electronic device reproducing the audio and video of the first application based on the event information of the first application. 
     In some embodiments, the electronic device includes a microphone. The second application provides an option (e.g., affordance  808 ) for recording audio data and video data of the first application and audio received at the microphone of the device. 
     In some embodiments, the electronic device includes a microphone and a camera sensor (e.g.,  164 ). The second application provides an option (e.g.,  810 ) for recording audio data and video data of the first application, audio received at the microphone of the device, and video received at the camera sensor (e.g.,  164 ) of the device. 
     In some embodiments, while recording, the electronic device displays, on the display, a picture-in-picture video (e.g.,  816 ) of the video received at the camera sensor (e.g.,  164 ) of the device. For example, the device records the video received at the camera sensor as a data stream. For example, the video received at the camera sensor captures the user&#39;s reactions (e.g., facial expressions) as the user is playing the game. The device also displays the video received at the camera sensor during the recording (e.g., live or near-live) to allow the user to see the camera&#39;s field of view (e.g., what is being recorded). 
     In some embodiments, the electronic device initiates the recording of the at least one data stream of the one or more data streams includes storing each data stream of the at least one data stream separately in memory (e.g., so that the data streams can be combined or not combined at a later time to create a multimedia file). 
     In some embodiments, initiating the recording of the at least one data stream of the one or more data streams includes storing, to memory, synchronization data to synchronize playback of the at least one data stream (e.g., so that the data streams can be synchronized at a later time such that the audio/video of the application are in sync with any recording audio from the microphone and any recorded video from the camera sensor). 
     In some embodiments, while recording of the at least one data stream of one or more data streams is in progress, the electronic device displays a visual indicator (e.g.,  812 ) of the second application that indicates the at least one data stream of the one or more data streams is being recorded. For example, the second application includes an indication that “The audio/video of the game and your voice are being recorded” or “Recording game+your audio/video.” For another example, a tongue (e.g.,  812 ) of the second application is displayed. 
     In some embodiments, as illustrated in  FIG. 8I , in response to detecting activation of the stop affordance, the electronic device displays, on the display, a second user interface (e.g.,  820 ) of the second application, wherein the second user interface of the second application provides an option (e.g.,  822 ) for sharing (e.g., by email, by text message, via a social network) the recorded at least one data stream of the one or more data streams. 
     In some embodiments, as illustrated in  FIG. 8I , in response to detecting activation of the stop affordance (e.g.,  814 C), the electronic device displays, on the display, a second user interface (e.g.,  820 ) of the second application. The second user interface (e.g.,  820 ) of the second application provides one or more options to edit (e.g., affordance  824 ) or playback (e.g.,  826 ) the recorded at least one data stream of the one or more data streams. For example, the second user interface (e.g.,  820 ) allows one or more of the following: playback of recorded streams (individually, a subset, or together), trimming of recorded streams, adding voiceover (using a microphone of the device) to recorded streams, adding picture-in-picture video (using a camera sensor of the device) to recorded streams, overlaying indications of measured galvanic skin response data to recorded streams, overlaying indications of measured heart rate data to recorded streams, enabling and disabling of visual or audio indications corresponding to touch information from a touch-sensitive surface captured during the recording, combining portions of different streams during different times of the recording (e.g., turn on video picture-in-picture for a portion of the recording) using recorded individual streams. 
     In some embodiments, the one or more data streams include a remote data stream received from a second electronic device different from the first electronic device. For example, the electronic device receives heart rate information detected by a paired smartwatch or recorded video information received from a camera sensor of a connected smartphone. For example, heart rate information (e.g.,  823 ) is displayed concurrently with the playback of audio/video of the second application, allowing a user of the device to correlate the user&#39;s heart rate with a portion of the game. 
     In some embodiments, the electronic device stores a temporal marker. The temporal marker is associated with a time of at least one of the one or more data streams and wherein the temporal marker is based on information received from the first application (e.g., the game). The temporal marker allows marking at location of the data stream that is not at the beginning or end of the data stream. For example, the second application creates markers based on information from the second application (e.g., times when achievements were unlocked, laps were completed, levels began or ended, etc.) to allow the user to subsequently quickly access, review, or those marked portions of the recording. 
     In some embodiments, the electronic device generates a highlight data stream based on the temporal marker and based on a portion (e.g., but not all) of the at least one data stream of the one or more data streams. For example, the electronic device puts together a highlight video. In some embodiments, the portions of the at least one data stream of the one or more data streams included in the highlight video are based on measured galvanic skin response data collected during the recording or heart rate data measured during the recording. In some embodiments, the electronic device determines that a user has opted-in, the electronic device indexes recordings at different points in a game using predefined markers and uploads the videos to one or more servers. The electronic device then enables users to search for uploaded videos that include a requested marker so that users can view the videos. This allows users to quickly find videos that they can watch to see how other players have played a particular level or aspect of a game, such has how players have solved a puzzle in a game. 
       FIG. 9  is a flow diagram illustrating a method for recording data streams using an electronic device in accordance with some embodiments. Method  900  is performed at a device (e.g.,  100 ,  300 ,  500 ) with a display. Some operations in method  900  may be combined, the order of some operations may be changed, and some operations may be omitted. 
     As described below, method  900  provides an intuitive way for recording data streams. The method reduces the cognitive burden on a user for recording data streams, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to recording data streams faster and more efficiently conserves power and increases the time between battery charges. 
     At block  902 , the electronic device concurrently displays, on the display, the user interface (e.g.,  802 ) for a first application (e.g., a game application, a workout application for an outdoor work out such as a run or bike ride or an indoor workout) and a user interface (e.g.,  804 A;  804 B; a control user interface without a recording affordance; a control user interface with a recording affordance; a recording affordance  810 ) for a second application (e.g., an operating system of the electronic device or another application on the electronic device that has privileges to record data streams associated with user activity while using the device that the first application is prohibited from recording). At least a portion of the user interface (e.g.,  804 A;  804 B;  810 ) for the first application is overlaid by at least a portion of the user interface for the second application. The user interface (e.g.,  804 A;  804 B;  810 ) for the second application includes a record affordance (e.g., which is part of the at least a portion of the user interface for the second application). 
     At block  904 , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the record affordance (e.g.,  810 ). 
     At block  906 , in response to detecting activation of the record affordance (e.g.,  810 ), the electronic device initiates (e.g., by the second application) a recording of at least one data stream of one or more data streams. In some examples, the at least one of the data streams includes a data stream associated with the first application (e.g., the video or audio output of the first application). For example, the electronic device displays an indication (e.g.,  818 ) that indicates that the electronic device is recording one or more data streams. 
     At block  908 , the electronic device displays, on the user interface for the second application, a stop affordance (e.g., control user interface with stop affordance  832 ; a standalone stop affordance). In some examples, the stop affordance is displayed in response to detecting a vertical swipe. 
     At block  910 , the electronic device detects (e.g., by the second application) activation (e.g., by the user) of the stop affordance (e.g.,  832 ). 
     At block  912 , in response to detecting activation of the stop affordance, the electronic device stops recording of the at least one data stream of the one or more data streams. 
     In some embodiments, the electronic device includes a touch-sensitive surface. Prior to concurrently displaying, on the display, the user interface for the first application and the user interface for the second application, the electronic device receives a first swipe input in a first direction (e.g., up direction) at the touch-sensitive surface. In response to receiving the swipe input, the electronic device displays a control user interface (e.g.,  804 A) for the second application. The control user interface does not include the record affordance. While displaying the control user interface (e.g.,  804 A) for the second application, the electronic device receives a second swipe input in a second direction (e.g., left direction) at the touch-sensitive surface (e.g., at a location corresponding to the control user interface (e.g.,  804 A). The record affordance (e.g.,  810 ) of the user interface for the second application is displayed as part of the control user interface (e.g.,  804 B) in response to receiving the second swipe input. 
     Prior to concurrently displaying, on the display, the user interface (e.g.,  802 ) for the first application and the user interface (e.g.,  804 B) for the second application, the electronic device receives a request to display controls for controlling functions of the second application (e.g., a request to display user interface  804 A). In response to receiving the request to display the control user interface (e.g.,  804 A,  804 B), the electronic device displays a control user interface that includes one or more controls (e.g.,  834 A,  834 B; for controlling functions of the second application. In some embodiments, the control user interface is displayed concurrently with at least a portion of the user interface of the first application. In some embodiments, the control user interface is displayed as a semi-transparent or transparent overlay on top of at least a portion of the user interface of the first application. In some embodiments, the control user interface includes other options for controlling functions of the device that are managed by the second application, such as volume (e.g., by  834 B), the on/off status of wireless antennas (e.g., by  834 C), media playback, etc. While the control user interface (e.g.,  804 A,  804 B) is displayed, the electronic device displays the record affordance  810  as part of the control user interface (e.g.,  804 B). 
     In some embodiments, in response to detecting activation of the record affordance (e.g.,  810 ), the electronic device updates the display to not include the record affordance (e.g.,  810 ). For example, the record affordance is replaced with the stop affordance. For another example, in response to detecting activation of the record affordance (e.g.,  810 ), the control user interface (e.g.,  804 A,  804 B including the user interface for the second application) slides away (e.g., down) and off the display. In some embodiments, when the control user interface slides away, a tongue (e.g.,  812 ; a handle) for the control user interface starts (or continues) to be displayed (e.g., overlaid on top of the user interface of the first application). The tongue (e.g.,  812 ) indicates that recording is in progress. In some examples, the tongue (e.g.,  812 ) also includes a displayed record time. 
     In some embodiments, the control user interface (e.g.,  804 A,  804 B) includes a record affordance (e.g.,  810 ) that is controlled by the second application (e.g., the operating system) and is overlaid on top of the user interface (e.g.,  802 ) for the first application (e.g., the game).

The second user interface (e.g.,  820 ) of the second application provides one or more options to edit (e.g., affordance  824 ) or playback (e.g.,  826 ) the recorded at least one data stream of the one or more data streams. For example, the second user interface (e.g.,  820 ) allows one or more of the following: playback of recorded streams (individually, a subset, or together), trimming of recorded streams, adding voiceover (using a microphone of the device) to recorded streams, adding picture-in-picture video (using a camera sensor of the device) to recorded streams, overlaying indications of measured galvanic skin response data to recorded streams, overlaying indications of measured heart rate data to recorded streams, enabling and disabling of visual or audio indications corresponding to touch information from a touch-sensitive surface captured during the recording, combining portions of different streams during different times of the recording (e.g., turn on video picture-in-picture for a portion of the recording) using recorded individual streams. 
     In some embodiments, the one or more data streams include a remote data stream received from a second electronic device different from the first electronic device. For example, the electronic device receives heart rate information detected by a paired smartwatch or recorded video information received from a camera sensor of a connected smartphone. For example, heart rate information (e.g.,  823 ) is displayed concurrently with the playback of audio/video of the second application, allowing a user of the device to correlate the user&#39;s heart rate with a portion of the game. 
     In some embodiments, the electronic device stores a temporal marker. The temporal marker is associated with a time of at least one of the one or more data streams and wherein the temporal marker is based on information received from the first application (e.g., the game). The temporal marker allows marking at location of the data stream that is not at the beginning or end of the data stream. For example, the second application creates markers based on information from the second application (e.g., times when achievements were unlocked, laps were completed, levels began or ended, etc.) to allow the user to subsequently quickly access, review, or those marked portions of the recording. 
     In some embodiments, the electronic device generates a highlight data stream based on the temporal marker and based on a portion (e.g., but not all) of the at least one data stream of the one or more data streams. For example, the electronic device puts together a highlight video. In some embodiments, the portions of the at least one data stream of the one or more data streams included in the highlight video are based on measured galvanic skin response data collected during the recording or heart rate data measured during the recording. In some embodiments, the electronic device determines that a user has opted-in, the electronic device indexes recordings at different points in a game using predefined markers and uploads the videos to one or more servers. The electronic device then enables users to search for uploaded videos that include a requested marker so that users can view the videos. This allows users to quickly find videos that they can watch to see how other players have played a particular level or aspect of a game, such has how players have solved a puzzle in a game. 
     Note that details of the processes described above with respect to method  900  (e.g.,  FIG. 9 ) are also applicable in an analogous manner to the methods described above. For example, method  700  optionally includes one or more of the characteristics of the various methods described above with reference to method  900 . For example, the data streams, affordances, and applications of method  700  optionally have one or more of the characteristics of the data streams, affordances, and applications of method  900 . For brevity, these details are not repeated.

Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, home addresses, or any other identifying information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. 
     The present disclosure further contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. For example, personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection should occur only after receiving the informed consent of the users. Additionally, such entities would take any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services. In another example, users can select not to provide location information for targeted content delivery services. In yet another example, users can select to not provide precise location information, but permit the transfer of location zone information. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publically available information.
