A telestrator or video marker system enables a user to sketch lines and other graphic objects over moving or still images. Telestrator systems are commonly used in television broadcasting to provide diagrams to viewers in contexts such as weather forecasting and sports commentary. Telestrator systems can also be used in classroom and conference settings to enable video and still images to be annotated with sketches as a way to facilitate analysis and comprehension. Current telestrator systems typically employ a user interface such as a touchscreen on which the user draws with a finger or a stylus.
This Background is provided to introduce a brief context for the Summary and Detailed Description that follow. This Background is not intended to be an aid in determining the scope of the claimed subject matter nor be viewed as limiting the claimed subject matter to implementations that solve any or all of the disadvantages or problems presented above.
A telestrator system running on a computing platform such as a personal computer or multimedia console having a coupled camera system, audio capture device, and a display screen, enables a video clip rendering on the platform to be telestrated with graphic objects including lines, arrows, or shapes that are drawn by a user using gestures that are captured by the camera system. The user can provide voice commentary while drawing on the video clip which is captured by the audio capture device in an audio track. The telestrator system exposes a user interface (“UI”) that enables the user to scrub the video clip to a desired point at which to telestrate, provides drawing markers having different colors, and also supports undo and clear capabilities to undo drawing strokes and clear all telestration drawings from the video clip. The telestrator system UI also exposes recording controls so that the user can record a video of the telestration session with the accompanying audio commentary which can then be saved and shared, for example, on a social network.
In various illustrative examples of the telestrator system, the user gestures employed as inputs to control the telestration drawings include an open palm gesture, a closed fist gesture, and a lasso gesture (using a pointing hand pose). For example, the user can employ the open palm gesture to move a cursor around the screen and perform button pushes. The closed fist gesture may be used to scrub the video backwards or forwards along a timeline. When the user drops the pinky and ring fingers to form the lasso gesture, the cursor changes to a marker icon and the user's hand motions are used to control the marker path on the screen to draw lines and other objects. The drawing stops when the user opens the hand to show the open palm gesture. Shape recognition and smoothing techniques can be applied to the user's as-drawn input so that when the user's hand opens, an idealized line or shape is displayed. Voice commands captured by the audio capture device can be used to control the telestrator system, for example, to change marker colors, undo previous drawing strokes, and clear the telestrated drawings from the video clip.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

Local content 120, including apps, games, and/or media content may also be utilized and/or consumed in order to provide a particular user experience 122 in the environment 100. In some cases the local content 120 is obtained from removable sources such as optical discs including DVDs (Digital Versatile Discs) and CDs (Compact Discs) while in others, the local content is downloaded from a remote source and saved locally. The user experience 122 may execute locally on the multimedia console 114, be hosted remotely by the entertainment service 102, or use a combination of local and remote execution in some cases using local or networked content/apps/games as appropriate. The user experience 122 may also be one in which multiple other players 124 with other computing devices can participate. In some implementations, a user experience can also be shared on a social network 126, as described in more detail below.
The user 112 can typically interact with the multimedia console 114 using a variety of different interface devices including a camera system 128 that can be used to sense visual commands, motions, and gestures, and a headset 130 or other type of microphone or audio capture device/system. In some cases a microphone and camera can be combined into a single device. The user 112 may also utilize a controller 132 to interact with the multimedia console 114. The controller 132 may include a variety of physical controls including joysticks, a directional pad (“D-pad”), and buttons. One or more triggers and/or bumpers (not shown) may also be incorporated into the controller 132. The user 112 will typically interact with a user interface 134 that is shown on a display device 136 such as a television or monitor.
It is emphasized that the number of controls utilized and the features and functionalities supported by the user controls implemented in the camera system 128, audio capture system, and controller 132 can vary from what is shown in
A telestrator app 138 executes on the multimedia console 114 in this illustrative example. As shown in
Each of the telestrator system capabilities 205 are described in more detail in the illustrative examples below.
In addition to IPTV viewing, the multimedia console 114 is typically configured for running gaming and non-gaming applications using local and/or networked programming and content, playing pre-recorded multimedia such as optical discs including DVDs (Digital Versatile Discs) and CDs (Compact Discs), streaming multimedia (e.g., music and video) from a network, participating in social media, browsing the Internet and other networked media and content, or the like using a coupled audio/visual display such as the television 136. In some implementations, the multimedia console 114 may be configured to support conventional cable television (“CATV”) sources using, for example, an HDMI (High Definition Multimedia Interface) connection.
The multimedia console 114 is operatively coupled to the camera system 128 which may be implemented using one or more video cameras that are configured to visually monitor a physical space 405 that is indicated generally by the dashed line in
For example as shown in
The camera system 128 can also be utilized to capture, track, and analyze movements by the user 112 to control gameplay as a gaming application executes on the multimedia console 114. For example, as shown in
The present telestrator system uses several gestures to enable the user 112 to interact with the telestrator app 138 to telestrate portions of the IPTV video clip 302. As respectively shown in
When the user drops the pinky and ring finger to place the hand into a “lasso” pose, the cursor changes into a marker icon 705 and the user's hand movement is drawn as a dotted line 710 onto the UI 134, as shown in
The user 112 can use the closed fist gesture 800 to scrub along a video timeline 805 in order to navigate to a desired point in the clip, as shown in
As shown in
The telestrator companion panel 915 includes a record control button 920 that enables the user 112 to record and save a telestration session. In this illustrative example, the user 112 can draw in telestrator mode using four different colors including yellow, red, blue, and white. The colors are selected using the color selection buttons 925. In addition, the user 112 can use a voice command (e.g., by saying “red”) to select a drawing color. An undo button 930 may be used to erase the last stroke of a drawing, and the clear button 935 removes all telestrator drawings from the UI 134 when invoked. A share button 940 may be used to open a sharing menu, window, or dialogue to enable the user to share a saved telestration session with the user's social graph (e.g., friends, family, colleagues, etc.) on a social network. The functionalities of the undo, clear, and share buttons may also be invoked using voice commands (e.g., by saying “undo,” “clear,” and “share” or their non-English language equivalents) as described in more detail below.
With the video paused at a desired point of interest, the user 112 uses the open palm gesture to move the cursor 605 to the record control button 920 and implement a press by hand motions in the z direction as indicated by the arrows 945. Typically, the user will telestrate over a still image from the video clip, but in some cases the telestration can be performed over a segment of motion video. For example, the video clip may include live action that is appropriate for telestrating or include slow-motion footage that the user may wish to draw on.
When a button is pressed on the telestrator companion panel its border is highlighted on the UI 134 as shown. The record control button press starts a video recording of the telestration session that shows lines being drawn over the video clip 302 in real time and also includes an audio track of commentary captured by the microphone in the headset or camera system. The recorded video of the telestration session is typically locally saved on the multimedia console 114 and can be shared later on a social network or stored/uploaded to another cloud-based service, for example.
As shown in
The user 112 next wants to change the marker color from the default yellow. As shown in
If the user 112 says the voice command “clear,” as indicated by reference numeral 2115 in
The user 112 can scrub the video clip by first moving the cursor to the video playhead 810 using the open palm gesture. Then, as shown in
When the user 112 is finished with his analysis and wishes to stop telestrating, he can use the open palm gesture 600 to move the cursor 605 to the recording control button and use button press motions to stop the recording of the telestration session. As noted above, the recorded video of the telestration session and the accompanying audio track of commentary is typically saved locally on the multimedia console 114, although it may also be remotely saved (e.g., in the cloud or on a remote server or other computing platform or device), or be saved using a combination of local and remote storage. In some cases the telestrator app 138 can expose saving options to the user 112 or the user can select how recorded telestration sessions are saved in a preferences menu, window, or dialogue. For example, the recorded session may be saved as a telestrated user experience in the form of a video and/or one or more still images (with or without the accompanying audio track).
In step 2705, the multimedia console 114 receives and renders an IPTV video clip from a remote source such as the entertainment service 102 (
At step, 2725, the camera system 128 will capture open palm gestures 600 and presses from the user 112 to operate the recording control 920 exposed on the telestrator companion panel 915. At step 2730, when the recording control is pressed to start a recording, the telestrator app 138 records a video of the telestration session including the user's drawings as they are drawn in real time and the underlying image or motion video from the clip. At step 2735, the user's voice commentary is captured by a microphone and recorded and saved as an accompanying audio track.
At step 2740, the camera system 128 captures the user's lasso gesture 700 to begin a drawing stroke. When the user 112 opens his hand to show the open palm gesture 600, the drawing stroke ends at step 2745. At step 2750, the user 112 can use open palm gestures and button presses or voice commands to change the marker color (as noted above, the default marker color is yellow in one particular illustrative embodiment). At step, 2755, the camera system 128 can capture open palm gestures 600 and button presses or voice commands to undo drawing strokes or clear telestration drawings from the UI. At step 2760, the video recording of the telestration session is saved, either locally, remotely, or using some combination of local and remote storage.
At step 2765, the user 112 can use open palm gestures 600 and button presses or voice commands to open a sharing menu in order to share video recordings of telestration sessions over a network at step 2770. As noted above, the sharing menu will typically provide options for the user to select which videos are shared, which members of the user's social graph they are shared with, and which social networks are utilized for the sharing.
As shown in
Various techniques may be utilized to capture depth video frames. For example, in time-of-flight analysis, the IR light component 2810 of the camera system 128 may emit an infrared light onto the capture area and may then detect the backscattered light from the surface of one or more targets and objects in the capture area using, for example, the IR camera 2815 and/or the RGB camera 2820. In some embodiments, pulsed infrared light may be used such that the time between an outgoing light pulse and a corresponding incoming light pulse may be measured and used to determine a physical distance from the camera system 128 to a particular location on the targets or objects in the capture area. Additionally, the phase of the outgoing light wave may be compared to the phase of the incoming light wave to determine a phase shift. The phase shift may then be used to determine a physical distance from the camera system to a particular location on the targets or objects. Time-of-flight analysis may be used to indirectly determine a physical distance from the camera system 128 to a particular location on the targets or objects by analyzing the intensity of the reflected beam of light over time via various techniques including, for example, shuttered light pulse imaging.
In other implementations, the camera system 128 may use structured light to capture depth information. In such an analysis, patterned light (i.e., light displayed as a known pattern such as a grid pattern or a stripe pattern) may be projected onto the capture area via, for example, the IR light component 2810. Upon striking the surface of one or more targets or objects in the capture area, the pattern may become deformed in response. Such a deformation of the pattern may be captured by, for example, the IR camera 2815 and/or the RGB camera 2820 and may then be analyzed to determine a physical distance from the camera system to a particular location on the targets or objects.
The camera system 128 may utilize two or more physically separated cameras that may view a capture area from different angles, to obtain visual stereo data that may be resolved to generate depth information. Other types of depth image arrangements using single or multiple cameras can also be used to create a depth image. The camera system 128 may further include a microphone 2825. The microphone 2825 may include a transducer or sensor that may receive and convert sound into an electrical signal. The microphone 2825 may be used to reduce feedback between the camera system 128 and the multimedia console 114 in the target recognition, analysis, and tracking system 2800. Additionally, the microphone 2825 may be used to receive audio signals that may also be provided by the user 112 to control applications such as game applications, non-game applications, or the like that may be executed by the multimedia console 114.
The camera system 128 may further include a processor 2830 that may be in operative communication with the image camera component 2805 over a bus 2840. The processor 2830 may include a standardized processor, a specialized processor, a microprocessor, or the like that may execute instructions that may include instructions for storing profiles, receiving the depth image, determining whether a suitable target may be included in the depth image, converting the suitable target into a skeletal representation or model of the target, or any other suitable instruction. The camera system 128 may further include a memory component 2845 that may store the instructions that may be executed by the processor 2830, images or frames of images captured by the cameras, user profiles or any other suitable information, images, or the like. According to one example, the memory component 2845 may include RAM, ROM, cache, Flash memory, a hard disk, or any other suitable storage component. As shown in
The camera system 128 operatively communicates with the multimedia console 114 over a communication link 2850. The communication link 2850 may be a wired connection including, for example, a USB (Universal Serial Bus) connection, a Firewire connection, an Ethernet cable connection, or the like and/or a wireless connection such as a wireless IEEE 802.11 connection. The multimedia console 114 can provide a clock to the camera system 128 that may be used to determine when to capture, for example, a scene via the communication link 2845. The camera system 128 may provide the depth information and images captured by, for example, the IR camera 2815 and/or the RGB camera 2820, including a skeletal model and/or facial tracking model that may be generated by the camera system 128, to the multimedia console 114 via the communication link 2850. The multimedia console 114 may then use the skeletal and/or facial tracking models, depth information, and captured images to, for example, create a virtual screen, adapt the user interface, and control apps/games 2850. The apps/games 2855 may include the telestrator app 138 (
A motion tracking engine 2860 uses the skeletal and/or facial tracking models and the depth information to provide a control output to one more apps/games 2855 running on the multimedia console 114 to which the camera system 128 is coupled. The information may also be used by a gesture recognition engine 2865, depth image processing engine 2870, and/or operating system 2875.
The depth image processing engine 2870 uses the depth images to track motion of objects, such as the user and other objects. The depth image processing engine 2870 will typically report to the operating system 2875 an identification of each object detected and the location of the object for each frame. The operating system 2875 can use that information to update the position or movement of an avatar, for example, or other images shown on the display 136, or to perform an action on the user interface.
The gesture recognition engine 2865 may utilize a gestures library (not shown) that can include a collection of gesture filters, each comprising information concerning a gesture that may be performed, for example, by a skeletal model (as the user moves). The gesture recognition engine 2865 may compare the frames captured by the camera system 114 in the form of the skeletal model and movements associated with it to the gesture filters in the gesture library to identify when a user (as represented by the skeletal model) has performed one or more gestures. Those gestures may be associated with various controls of an application and direct the system to open the personalized home screen as described above. Thus, the multimedia console 114 may employ the gestures library to interpret movements of the skeletal model and to control an operating system or an application running on the multimedia console based on the movements.
In some implementations, various aspects of the functionalities provided by the apps/games 2855, motion tracking engine 2860, gesture recognition engine 2865, depth image processing engine 2870, and/or operating system 2875 may be directly implemented on the camera system 128 itself.
A graphics processing unit (GPU) 2908 and a video encoder/video codec (coder/decoder) 2914 form a video processing pipeline for high speed and high resolution graphics processing. Data is carried from the GPU 2908 to the video encoder/video codec 2914 via a bus. The video processing pipeline outputs data to an A/V (audio/video) port 2940 for transmission to a television or other display. A memory controller 2910 is connected to the GPU 2908 to facilitate processor access to various types of memory 2912, such as, but not limited to, a RAM.
The multimedia console 114 includes an I/O controller 2920, a system management controller 2922, an audio processing unit 2923, a network interface controller 2924, a first USB (Universal Serial Bus) host controller 2926, a second USB controller 2928, and a front panel I/O subassembly 2930 that are preferably implemented on a module 2918. The USB controllers 2926 and 2928 serve as hosts for peripheral controllers 2942(1) and 2942(2), a wireless adapter 2948, and an external memory device 2946 (e.g., Flash memory, external CD/DVD ROM drive, removable media, etc.). The network interface controller 2924 and/or wireless adapter 2948 provide access to a network (e.g., the Internet, home network, etc.) and may be any of a wide variety of various wired or wireless adapter components including an Ethernet card, a modem, a Bluetooth module, a cable modem, or the like.
System memory 2943 is provided to store application data that is loaded during the boot process. A media drive 2944 is provided and may comprise a DVD/CD drive, hard drive, or other removable media drive, etc. The media drive 2944 may be internal or external to the multimedia console 114. Application data may be accessed via the media drive 2944 for execution, playback, etc. by the multimedia console 114. The media drive 2944 is connected to the I/O controller 2920 via a bus, such as a Serial ATA bus or other high speed connection (e.g., IEEE 1394).
The system management controller 2922 provides a variety of service functions related to assuring availability of the multimedia console 114. The audio processing unit 2923 and an audio codec 2932 form a corresponding audio processing pipeline with high fidelity and stereo processing. Audio data is carried between the audio processing unit 2923 and the audio codec 2932 via a communication link. The audio processing pipeline outputs data to the A/V port 2940 for reproduction by an external audio player or device having audio capabilities.
The front panel I/O subassembly 2930 supports the functionality of the power button 2950 and the eject button 2952, as well as any LEDs (light emitting diodes) or other indicators exposed on the outer surface of the multimedia console 114. A system power supply module 2936 provides power to the components of the multimedia console 114. A fan 2938 cools the circuitry within the multimedia console 114.
The CPU 2901, GPU 2908, memory controller 2910, and various other components within the multimedia console 114 are interconnected via one or more buses, including serial and parallel buses, a memory bus, a peripheral bus, and a processor or local bus using any of a variety of bus architectures. By way of example, such architectures can include a Peripheral Component Interconnects (PCI) bus, PCI-Express bus, etc.
When the multimedia console 114 is powered ON, application data may be loaded from the system memory 2943 into memory 2912 and/or caches 2902 and 2904 and executed on the CPU 2901. The application may present a graphical user interface that provides a consistent user experience when navigating to different media types available on the multimedia console 114. In operation, applications and/or other media contained within the media drive 2944 may be launched or played from the media drive 2944 to provide additional functionalities to the multimedia console 114.
The multimedia console 114 may be operated as a standalone system by simply connecting the system to a television or other display. In this standalone mode, the multimedia console 114 allows one or more users to interact with the system, watch movies, or listen to music. However, with the integration of broadband connectivity made available through the network interface controller 2924 or the wireless adapter 2948, the multimedia console 114 may further be operated as a participant in a larger network community.
When the multimedia console 114 is powered ON, a set amount of hardware resources are reserved for system use by the multimedia console operating system. These resources may include a reservation of memory (e.g., 16 MB), CPU and GPU cycles (e.g., 5%), networking bandwidth (e.g., 8 kbps), etc. Because these resources are reserved at system boot time, the reserved resources do not exist from the application's view.
In particular, the memory reservation preferably is large enough to contain the launch kernel, concurrent system applications, and drivers. The CPU reservation is preferably constant such that if the reserved CPU usage is not used by the system applications, an idle thread will consume any unused cycles.
With regard to the GPU reservation, lightweight messages generated by the system applications (e.g., pop-ups) are displayed by using a GPU interrupt to schedule code to render pop-ups into an overlay. The amount of memory needed for an overlay depends on the overlay area size and the overlay preferably scales with screen resolution. Where a full user interface is used by the concurrent system application, it is preferable to use a resolution independent of application resolution. A scaler may be used to set this resolution such that the need to change frequency and cause a TV re-sync is eliminated.
After the multimedia console 114 boots and system resources are reserved, concurrent system applications execute to provide system functionalities. The system functionalities are encapsulated in a set of system applications that execute within the reserved system resources described above. The operating system kernel identifies threads that are system application threads versus gaming application threads. The system applications are preferably scheduled to run on the CPU 2901 at predetermined times and intervals in order to provide a consistent system resource view to the application. The scheduling is to minimize cache disruption for the gaming application running on the console.
When a concurrent system application requires audio, audio processing is scheduled asynchronously to the gaming application due to time sensitivity. A multimedia console application manager (described below) controls the gaming application audio level (e.g., mute, attenuate) when system applications are active.
Input devices (e.g., controllers 2942(1) and 2942(2)) are shared by gaming applications and system applications. The input devices are not reserved resources, but are to be switched between system applications and the gaming application such that each will have a focus of the device. The application manager preferably controls the switching of input stream, without knowledge of the gaming application's knowledge and a driver maintains state information regarding focus switches.
A number of program modules may be stored on the hard disk, magnetic disk 3033, optical disk 3043, ROM 3017, or RAM 3021, including an operating system 3055, one or more application programs 3057, other program modules 3060, and program data 3063. A user may enter commands and information into the computer system 3000 through input devices such as a keyboard 3066 and pointing device 3068 such as a mouse. Other input devices (not shown) may include a microphone, joystick, game pad, satellite dish, scanner, trackball, touchpad, touch screen, touch-sensitive module or device, gesture-recognition module or device, voice recognition module or device, voice command module or device, or the like.

A monitor 3073 or other type of display device is also connected to the system bus 3014 via an interface, such as a video adapter 3075. In addition to the monitor 3073, personal computers typically include other peripheral output devices (not shown), such as speakers and printers. The illustrative example shown in
The computer system 3000 is operable in a networked environment using logical connections to one or more remote computers, such as a remote computer 3088. The remote computer 3088 may be selected as another personal computer, a server, a router, a network PC, a peer device, or other common network node, and typically includes many or all of the elements described above relative to the computer system 3000, although only a single representative remote memory/storage device 3090 is shown in
When used in a LAN networking environment, the computer system 3000 is connected to the local area network 3093 through a network interface or adapter 3096.

The broadband modem 3098, which may be internal or external, is connected to the system bus 3014 via a serial port interface 3071. In a networked environment, program modules related to the computer system 3000, or portions thereof, may be stored in the remote memory storage device 3090. It is noted that the network connections shown in
