Abstract: A central server receives a venue identification query from a client device in the venue and a test data set including information collected from the venue. The central server then queries a classifier to identify the venue based on the test data. The classifier returns an identity value (venue ID) and a confidence value for the venue ID. When the confidence value is less than a threshold value, the central server obtains additional data from the client device until the venue is identified. The central server associates the venue ID with the test data set, including the additional data, and adds the test data set to training data for the classifier.

Abstract: A method includes obtaining data representing multiple characters, determining a code for each character wherein each code corresponds to a different audio frequency, and transmitting the codes at the corresponding audio frequencies.

Abstract: Techniques for recording and replay of a live conference while still attending the live conference are described. A conferencing system includes a user interface generator, a live conference processing module, and a replay processing module. The user interface generator is configured to generate a user interface that includes a replay control panel and one or more output panels. The live conference processing module is configured to extract information included in received conferencing data that is associated with one or more conferencing modalities, and to display the information in the one or more output panels in a live manner (e.g., as a live conference). The replay processing module is configured to enable information associated with the one or more conferencing modalities corresponding to a time of the conference session prior to live to be presented at a desired rate, possibly different from the real-time rate.

Abstract: A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image.

Abstract: An example system includes a plurality of moveable light emitters, each moveable light emitter configured to independently emit a display light from a current display location within that moveable light emitter's range of motion responsive to activation from a corresponding light activator. The system also includes a location engine to determine, for each light emitter, the current display location of that light emitter, and a mapping engine to map, for each current display location, the light activator activating the light emitter currently located at that current display location.

Abstract: Techniques for automatically connecting to a service controller are described herein. In one example, a service controller device includes a processor and a computer-readable memory storage device storing executable instructions that cause the processor to broadcast at least one of an access credential, connection information or an access credential hash embedded in an audio signal. The processor can also authenticate a client device based on a transmission of at least one of the connection information, the access credential, or the access credential hash from the client device to the client connector and transmit data to the client device in response to authenticating the client device.

Abstract: The claimed subject matter includes techniques for discovering to and connecting to a service controller. The claimed subject matter may disclose a processor and a memory of a service controller to store connection information, an access credential, and an access credential hash. A beacon broadcaster to broadcast the connection information and the access credential hash to a client device, may also be disclosed. The present disclosure may also include an access credential director to send the access credential to an out-of-band communicator. The present disclosure may also include a client connector to receive a connection request from the client device and allow access to a client device based on the client device's use of the connection information.

Abstract: In some examples, a system senses the location of a stylus or finger of a user relative to a virtual displayed object to determine when a virtual touch occurs. Upon or after such a determination, the system may generate a haptic action that indicates to the user that the virtual touch occurred. The haptic action may be located on a particular portion of a haptic device, which may be a handheld device. The particular portion may correspond to the location where the virtual displayed object was virtually touched. In this way, the user may receive physical feedback associated with the virtual touch of the virtual displayed object. In some examples, the virtual displayed object may change in response to the virtual touch, thus further providing visual and physical feedback associated with the virtual touch of the virtual displayed object to the user.

Abstract: The interactive and shared surface technique described herein employs hardware that can project on any surface, capture color video of that surface, and get depth information of and above the surface while preventing visual feedback (also known as video feedback, video echo, or visual echo). The technique provides N-way sharing of a surface using video compositing. It also provides for automatic calibration of hardware components, including calibration of any projector, RGB camera, depth camera and any microphones employed by the technique. The technique provides object manipulation with physical, visual, audio, and hover gestures and interaction between digital objects displayed on the surface and physical objects placed on or above the surface. It can capture and scan the surface in a manner that captures or scans exactly what the user sees, which includes both local and remote objects, drawings, annotations, hands, and so forth.

Abstract: The large display interaction implementations described herein combine mobile devices with people tracking to enable new interactions including making a non-touch-sensitive display touch-sensitive and allowing personalized interactions with the display. One implementation tracks one or more mobile computing device users relative to a large computer-driven display, and configures content displayed on the display based on a distance a given mobile computing device user is from the display. Another implementation personalizes user interactions with a large display. One or more mobile computing device users are tracked relative to a display. The identity of each of the one or more mobile computing device users is obtained. Content displayed on the display is configured based on a distance an identified mobile computing device user is from the display and the identity of the user that provides the content.

Abstract: Aspects of the subject disclosure are directed towards providing contextual information (such as high resolution still images) during an audio or video call. A receiver of the contextual information may send commands to the sending device to specify a desired resolution and frame rate of such images. A receiving user also may determine how to display any video call frames and/or the contextual information on one or more display devices available to the receiving user. Other contextual information such as location-related data by which a user can determine and display a location of the other call participant (or participants) may be transmitted during the call.

Abstract: A local user of a local mobile device is allowed to participate in a video conference session with a remote user of a remote mobile device. Live video can be shared between and collaboratively digitally annotated by the local and remote users. An application can also be shared between and collaboratively digitally annotated by the local and remote users. A digital object can also be shared between and collaboratively digitally annotated by the local and remote users.

Abstract: Multi-device capture and spatial browsing of conferences is described. In one implementation, a system detects cameras and microphones, such as the webcams on participants' notebook computers, in a conference room, group meeting, or table game, and enlists an ad-hoc array of available devices to capture each participant and the spatial relationships between participants. A video stream composited from the array is browsable by a user to navigate a 3-dimensional representation of the meeting. Each participant may be represented by a video pane, a foreground object, or a 3-D geometric model of the participant's face or body displayed in spatial relation to the other participants in a 3-dimensional arrangement analogous to the spatial arrangement of the meeting. The system may automatically re-orient the 3-dimensional representation as needed to best show a currently interesting event.
