摘要： Techniques are provided to determine the horizontal gaze of a person from a video signal generated from viewing the person with at least one video camera. From the video signal, a head region of the person is detected and tracked. The dimensions and location of a sub-region within the head region is also detected and tracked from the video signal. An estimate of the horizontal gaze of the person is computed from a relative position of the sub-region within the head region.

摘要： A system and method for creating a virtual round table videoconference is described. An embodiment of the system comprises a plurality of displays arranged in an configuration with a table to create a virtual round table. Cameras are arranged around the plurality of displays such that when a participant looks at a display with a image of a remote participant, the camera associated with the display captures an image of the participant's gaze, making eye contact with the camera. The image is displayed at the remote participant's endpoint creating the effect of eye contact between the participants. In another embodiment, audio speakers are arranged to provide directional sound that the video source for a display and the audio source for the associated speaker are from the same endpoint.

摘要： Techniques are provided for establishing a videoconference session between participants at different endpoints, where each endpoint includes at least one computing device and one or more displays. A plurality of video streams is received at an endpoint, and each video stream is classified as at least one of a people view and a data view. The classified views are analyzed to determine one or more regions of interest for each of the classified views, where at least one region of interest has a size smaller than a size of the classified view. Synthesized views of at least some of the video streams are generated, wherein the synthesized views include at least one view including a region of interest, and views including the synthesized views are rendered at one or more displays of an endpoint device.
