摘要： The discussion relates to context-aware environments. One example can include inwardly-facing cameras positioned around a periphery of an environment that defines a volume. The example can also include sensors positioned relative to the volume and configured to communicate with a user device in the volume. The example can also include an ambient perception component configured to track user locations in the volume and to detect user gestures relative to objects in the volume, and responsive to receiving a query from the user's device, to supplement the query with information derived from the objects.

摘要： 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.

摘要： Implementations provide an in-person communication experience by generating a changable virtual viewpoint for a participant in an online communication. For instance, techniques described herein capture visual data about participants in an online communication, and create a realistic geometric proxy from the visual data. A virtual scene geometry is generated that mimics an arrangement of an in-person meeting for the online communication. According to various implementations, a virtual viewpoint displays a changing virtual viewpoint, such as based on a change in position of a participants face.

摘要： In embodiments of collaborative camera viewpoint control for interactive telepresence, a system includes a vehicle that travels based on received travel instructions, and the vehicle includes a camera system of multiple cameras that each capture video of an environment in which the vehicle travels from different viewpoints. Viewing devices receive the video of the environment from the different viewpoints, where the video of the environment from a selected one of the viewpoints is displayable to users of the viewing devices. Controller devices that are associated with the viewing devices can each receive a user input as a proposed travel instruction for the vehicle based on the selected viewpoint of the video that is displayed on the viewing devices. A trajectory planner receives the proposed travel instructions initiated via the controller devices, and generates a consensus travel instruction for the vehicle based on the proposed travel instructions.

摘要： The subject disclosure is generally directed towards eye gaze detection based upon both eyes being fixated on the same gaze location. In one aspect, an image including a subject's left and right eyes is captured, from which left and right glint and pupil center information are extracted. The left and right glint data and the left and right pupil data are used with left and right bias correction matrices to jointly determine a gaze location.

摘要： The privacy-preserving energy-efficient speaker implementations described herein improve user privacy while a user is listening to audio and can reduce the energy necessary to output the audio. This can be done by using parametric speakers and/or traditional loud-speakers. Signal splitting and masking can be used to improve user privacy. Additionally, a signal modulation technique which significantly reduces power requirements to output an audio signal, especially in the context of using parametric speakers, can also be employed.

摘要： 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.

摘要： A perspective-correct communication window system and method for communicating between participants in an online meeting, where the participants are not in the same physical locations. Embodiments of the system and method provide an in-person communications experience by changing virtual viewpoint for the participants when they are viewing the online meeting. The participant sees a different perspective displayed on a monitor based on the location of the participant's eyes. Embodiments of the system and method include a capture and creation component that is used to capture visual data about each participant and create a realistic geometric proxy from the data. A scene geometry component is used to create a virtual scene geometry that mimics the arrangement of an in-person meeting. A virtual viewpoint component displays the changing virtual viewpoint to the viewer and can add perceived depth using motion parallax.

摘要： The disclosure relates to tracking the location of a target object. In one example, a computer vision system detects a configuration of environment objects. A location model that has been trained for the environment configuration is selected. A signal associated with the target object is received and interpreted using the selected location model to determine the location of the target object.
