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： Certain ones of a total array of ultrasonic transducers (11a-11n) constitute a small aperture and are so energized as to project acoustic energy onto predetermined parts of a scene (10). Reflections of the transmitted signals are received by certain ones of the array, are converted to electrical signals and are appropriately delayed to enable additive combination of the amplitude of the received signals emanating from the same points in the scene (10) ("targets"). The phase (or time delay) as well as the amplitude information of the reflective signals are stored. Next, the same transmitting elements ("subarray") project acoustic energy upon the remaining parts of the scene (10) in sequence and the reflected signals are similarly processed and stored. This continues until all the parts of the predetermined scene have been interrogated by insonification from that subarray and the reflected signals have been similarly processed. Then, at least one or more set of transducers of the total array, (11a-11n) which also constitute a small aperture, are caused to scan the same parts of the image in the same sequence thereby producing the same types of reflected signals which are processed similarly, and whose amplitude and phase information is similarly stored. The plurality of the stored signals from each subarray, which may be termed "complex image" signals, are then vectorially added and further processed to derive a video signal which is used to produce a final display image.

摘要： A telepresence apparatus, a method of operating a telepresence apparatus, and a tangible computer readable storage medium in a telepresence apparatus that is configured with instructions that when executed cause operating of the telepresence apparatus. The telepresence apparatus includes video cameras districted co-planar with a display wall and capturing camera views of a scene. The camera views from the video processor combined to form a video signal for transmission to one or more remote endpoints, the video signal corresponding to a synthetic view from a point that is substantially behind the wall and as if the wall was not there.

摘要： An apparatus, software encoded in tangible media, and a method at an encoder. The method includes sending compressed video data including a reference frame message to create a long term reference frame to a plurality of decoders at one or more destination points, receiving feedback from the decoders indicative of whether or not the decoders successfully received the reference frame message, and in the case that the received feedback is such that at least one of the decoders did not successfully receive the reference frame message or does not have the indicated recent frame, repeating sending a reference frame message to create the long term reference frame. Using the method can replace I-frame error recovery with long term reference frames, even in the case where the reference frame management messages are lost to at least one decoder.

摘要： A system and method for providing a plurality of viewing angles and images on a display. An embodiment comprises a display system where a user has the option of determining the number of images to view and the range of viewable angles for each image. A display system is configured to display a maximum number of images at different viewing angles by interlacing a plurality of images so that each viewing angle shows a selected image. The display system provides a method by which an operator can increase the viewing area of an image by interlacing the same image to more than one viewing angle.
