DETAILED DESCRIPTION

Example Media Lock Affordance

This disclosure relates to media recording functionality of a media capture device that locks a media capture affordance on a graphical user interface (GUI) into a locked media capture state for continuous media capture. In an embodiment, to initiate a media capture session of a media clip (e.g., a video clip, audio clip), the user taps and holds the media capture affordance (e.g., a virtual recording button). As long as the user holds their touch on the media capture affordance, the media continues to be captured by the media capture device. If the user removes their touch during the media capture session, the media capture session terminates. If the user maintains their touch on the media capture affordance while making a sliding gesture with their finger, the media capture affordance visually changes to a locked media capture affordance and the media capture session is maintained, resulting in continuous recording of the media. In an embodiment, the locked media capture affordance moves down below the user's finger so that it is not obscured by the user's finger. The user can remove their finger from the locked media capture affordance and the media capture session will be maintained until the user taps the locked state capture button, which then terminates the media capture session.

FIGS. 1A-1H illustrate operation of a media capture lock affordance, according to an embodiment. Referring to FIG. 1A, media capture device 100 is presenting GUI 101 on a display screen. GUI 101 includes media capture affordance 102. Media capture device 100 is shown in this example embodiment as a smartphone. Media capture device 100, however, can be any electronic device capable of capturing media, including tablet computers, wearable computers, digital cameras, video recorders and audio recording devices. Media capture affordance 102 can have any desired shape, size or color. In the example shown, media capture affordance 102 is an oval shape button. GUI 101 also includes a display area for displaying live media and playing back captured media. Media can be any type of media that can be captured, including video, still images and audio or any combination thereof.

Referring to FIG. 1B, a user taps and holds 103 (shown as a dashed circle) media capture affordance 102 with their finger (e.g., their thumb while holding media capture device 100) to initiate a media capture session in an “unlocked” state. During the media capture session, an embedded video camera and/or one or more microphones capture media (e.g., capture video and audio). The media capture session is “unlocked” meaning that if the user lifts their finger from media capture affordance 102 (lifts their finger off the display screen), the media capture session terminates, and the media is stored on media capture device 100 (e.g., stored in cache memory). Visual direction indicator 104a (e.g., an arrow head) is displayed on GUI 101 to indicate a direction in which the user may slide their finger to transition the media capture session into a “locked” state. While in the “locked” state, the media is continuously captured without interruption. For example, video and audio will continue to record and still images will be taken in “burst” mode. Text is also displayed on GUI 101 that instructs the user to “slide up for continuous recording.”

In some embodiments, additional affordances (not shown) are included on GUI 101 for allowing the user to playback the captured media (hereinafter also referred to as a “media clip”), and order, filter, add emoji, animated icons and titles to the media clip. Other affordances allow the user to share the media clips indirectly with social networking websites and directly with friends and family through various communication means (e.g., instant messaging, email, tweeting). In the embodiment shown, a navigation bar is located under the media display area that allows the user select an operation mode such as Camera, Library and Posters.

Referring to FIG. 1C, shows the user's slide gesture input resulting in media capture affordance 102 sliding up toward the media capture area. Note that during a slide gesture input the user's finger does not break contact with the display screen.

Referring to FIGS. 1D-1G, when the user slide media capture affordance 102 up a predetermined distance, media capture affordance 102 changes or morphs into media capture lock affordance 105 to visually indicate a “locked” state, as shown in FIG. 1F. The text below the media display area also changes to instruct the user how to exit the “locked” state such as, for example, “tap to stop recording.” Media capture lock affordance 105 can be any size, shape or color. In the example shown, media capture lock affordance 105 is a square button. After the change or morph from media capture affordance 102 to media capture lock affordance 105, if the user lifts their finger and breaks contact with the display screen, the media capture session enters the “locked” state. In the “locked” state the media capture session continues with the media capture until the user taps 106 media capture lock affordance 105 (FIG. 1G), in which case the media capture session terminates. In an alternative embodiment, visual direction indicator 104a can be replaced with button track 104b to show the user the distance the user should slide media capture affordance 102 to enter the “locked” state.

In other embodiments, multiple taps can be used instead of a single tap. The direction of the slide gesture input can be in any direction on GUI 101, including up, down, right and left. A sound effect can be played in sync with the tap and slide gesture, such as a “click” sound effect to indicate when the media capture session is locked and unlocked. In an embodiment, force feedback (e.g., a vibration) can be provided by a haptic engine to indicate when the media capture session is locked and unlocked. Affordances 102, 106 can be placed at any desired location on GUI 101, and can change location, size and/or shape in response to the orientation of media capture device 100, such as portrait and landscape orientations. In an embodiment, the user can enter or exit a locked media capture state using a voice command, which is processed by a speech detection/recognition engine implemented in media capture device 100.

Example Processes

FIG. 2 is a flow diagram of an animation process for the media capture lock affordance shown in FIGS. 1A-1H, according to an embodiment. Process 200 can be implemented using the device architecture 300 described in reference to FIG. 3.

Process 200 begins by receiving a tap and hold gesture input directed to a media capture affordance at a first location of a GUI presented on a display device of a media capture device (201). The media capture affordance can be and size, shape or color. The first location can be any desired location on the GUI. Responsive to the tap and hold gesture input, process 200 initiates a media capture session on the media capture device, where the media capture session is initiated in an “unlocked” state (202). Responsive to a first lift gesture at the first location, process 200 terminates the media capture session (203).

Responsive to a slide gesture input from the first location to a second location on the GUI, process 200 changes the media capture affordance to a media capture lock affordance (204). The media capture lock affordance can be any size, shape or color. The second location can be any desired location on the GUI except the first location. The slide gesture can be in any desired direction including up, down, left and right.

Responsive to detecting a second lift gesture at the second location, process 200 transitions the media capture session from an unlocked state into a locked state (205). In a locked state, the media capture device will capture media continuously, until the user taps the media capture lock affordance to terminate the media capture session. In an embodiment, the user can tap anywhere on the GUI to terminate the media capture session after the second lift gesture, or press a mechanical button on the media capture device (e.g., a home button on a smartphone).

Exemplary Mobile Device Architecture

FIG. 3 illustrates an example media capture device architecture 300 of a mobile device implementing the media capture lock affordance described in reference to FIGS. 1 and 2. Architecture 300 can include memory interface 302, one or more data processors, image processors and/or processors 304 and peripherals interface 306. Memory interface 302, one or more processors 304 and/or peripherals interface 306 can be separate components or can be integrated in one or more integrated circuits. The various components in architecture 300 can be coupled by one or more communication buses or signal lines.

Sensors, devices and subsystems can be coupled to peripherals interface 306 to facilitate multiple functionalities. For example, one or more motion sensors 310, light sensor 312 and proximity sensor 314 can be coupled to peripherals interface 306 to facilitate motion sensing (e.g., acceleration, rotation rates), lighting and proximity functions of the mobile device. Location processor 315 can be connected to peripherals interface 306 to provide geopositioning. In some implementations, location processor 315 can be a GNSS receiver, such as a Global Positioning System (GPS) receiver chip. Electronic magnetometer 316 (e.g., an integrated circuit chip) can also be connected to peripherals interface 306 to provide data that can be used to determine the direction of magnetic North. Electronic magnetometer 316 can provide data to an electronic compass application. Motion sensor(s) 310 can include one or more accelerometers and/or gyros configured to determine change of speed and direction of movement of the mobile device. Barometer 317 can be configured to measure atmospheric pressure around the mobile device.

Camera subsystem 320 and an optical sensor 322, e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as capturing photographs and recording video clips.

Communication functions can be facilitated through one or more wireless communication subsystems 324, which can include radio frequency (RF) receivers and transmitters (or transceivers) and/or optical (e.g., infrared) receivers and transmitters.

Touch surface 346 can include, for example, a touch screen. I/O subsystem 340 can include a haptic engine or device for providing haptic feedback (e.g., vibration) in response to commands from a processor.

Other input controller(s) 344 can be coupled to other input/control devices 348, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port and/or a pointer device such as a stylus.

Touch surface 346 or other controllers 344 (e.g., a button) can include, or be coupled to, fingerprint identification circuitry for use with a fingerprint authentication application to authenticate a user based on their fingerprint(s).

In one implementation, a pressing of the button for a first duration may disengage a lock of the touch surface 346; and a pressing of the button for a second duration that is longer than the first duration may turn power to the mobile device on or off. The user may be able to customize a functionality of one or more of the buttons. The touch surface 346 can, for example, also be used to implement virtual or soft buttons and/or a virtual touch keyboard.

In some implementations, the mobile device can present recorded audio and/or video files, such as MP3, AAC and MPEG files. In some implementations, the mobile device can include the functionality of an MP3 player. Other input/output and control devices can also be used.

Memory interface 302 can be coupled to memory 350. Memory 350 can include high-speed random access memory and/or non-volatile memory, such as one or more magnetic disk storage devices, one or more optical storage devices and/or flash memory (e.g., NAND, NOR). Memory 350 can store operating system 352, such as iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks. Operating system 352 may include instructions for handling basic system services and for performing hardware dependent tasks. In some implementations, operating system 352 can include a kernel (e.g., UNIX kernel).

Memory 350 may also store communication instructions 354 to facilitate communicating with one or more additional devices, one or more computers and/or one or more servers, such as, for example, instructions for implementing a software stack for wired or wireless communications with other devices.

Data generated at the client device (e.g., a result of the user interaction) can be received from the client device at the server.

A system of one or more computers can be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to perform the actions. One or more computer programs can be configured to perform particular actions by virtue of including instructions that, when executed by data processing apparatus, cause the apparatus to perform the actions.

One or more features or steps of the disclosed embodiments may be implemented using an Application Programming Interface (API). An API may define on or more parameters that are passed between a calling application and other software code (e.g., an operating system, library routine, function) that provides a service, that provides data, or that performs an operation or a computation. The API may be implemented as one or more calls in program code that send or receive one or more parameters through a parameter list or other structure based on a call convention defined in an API specification document. A parameter may be a constant, a key, a data structure, an object, an object class, a variable, a data type, a pointer, an array, a list, or another call. API calls and parameters may be implemented in any programming language. The programming language may define the vocabulary and calling convention that a programmer will employ to access functions supporting the API. In some implementations, an API call may report to an application the capabilities of a device running the application, such as input capability, output capability, processing capability, power capability, communications capability, etc.
