摘要： A method of communicating gaze. Specifically, one embodiment of the present invention discloses a method of communicating gaze in an immersive virtual environment. The method begins by representing an immersive virtual environment on a monitor that is viewable by a viewing participant. The monitor displays a plurality of objects in the virtual environment. The physical gaze of the viewing participant is tracked to determine a physical direction of the physical gaze within a physical environment including the viewing participant. Thereafter, a viewed object is determined at which the viewing participant is gazing. Then, a virtual direction is determined between the viewing participant and the viewed object in the immersive virtual environment. A model of the viewing participant is rotated based on the physical and virtual directions to render a view of the viewing participant such that the viewing participant is facing the viewed object in the immersive virtual environment.

摘要： A method and system for videoconferencing between parties at N sites. Specifically, a virtual space arrangement of N sites is created. Video sequences of N−1 remote sites are simultaneously displayed on a non-planar display arranged around a local party at a local site consistent with the virtual space arrangement. The displayed images of the remote parties are scaled consistently with their true physical sizes at their distances from the local party in the virtual space arrangement. Real-time video streams of the local party are captured from a plurality of viewpoints and are used to generate N−1 video view streams representing views of the local party from approximately the local display locations of the N−1 remote parties.

摘要： A method of generating a three-dimensional model of a scene from a plurality of photographs of the scene. The method includes voxels in an interior region and an exterior region of the scene in question and then examines the voxels to determine if they are empty or part of the objects in the scene. The interior region is divided into a plurality of interior voxels, that are preferably of the same size. The exterior region surrounds the interior space and is divided into exterior voxels having different sizes. The size of the exterior voxels increases as a function of the distance between the voxel and the interior region. The voxels that are furthest from the interior region are preferably infinite in size.

摘要： A three-dimensional model of a scene is reconstructed from a plurality of images of the scene taken from different viewpoints. A set of voxels that include the scene is defined, and each of the voxels in the set of voxels is processed. Each voxel is projected onto a set of pixels in each of the images. A first color-standard-deviation of not-occluded pixels is determined across all images. A second color-standard-deviation of not-occluded pixels is determined for each individual image. A mean of the second color-standard-deviations is determined across all images. A coloring threshold that is a function of the mean is established. If the first color-standard-deviation is less than the coloring threshold, the voxel is colored. Otherwise, the voxel is left transparent. The coloring threshold is established adaptively and depends on the color variation across the projection of the voxel in each individual image.

摘要： Computer programs are provided which utilize a touchscreen to emulate three-dimensional objects on a two-dimensional computer screen. One program, called personal cardfile (PCF), combines the convenience of a desktop rotary cardfile with the power of a computerized product. PCF presents an image of a rotary file, complete with "knobs" for flipping through "cards" in a cardfile, and "tabs" for selecting "cards" to be represented individually on the touchscreen. Another program, called financial computer (FC), emulates an HP12C handheld financial calculator. The HP12C calculator is manufactured by Hewlett-Packard Company, Palo Alto, Calif. On a computer touchscreen, an operator sees a familiar looking "calculator" and touches its "keys" to operate it, just as for a conventional three-dimensional calculator.

摘要： A method for real-time video communication. Specifically, one embodiment of the present invention discloses a method of video conferencing that captures a plurality of real-time video streams of a local participant from a plurality of sample viewpoints. From the plurality of video streams, a new view synthesis technique can be applied to generate a video image stream in real-time of the local participant rendered from a second location of a second participant with respect to a first location of the local participant in a coordinate space of a virtual environment. A change in either of the locations leads to the modifying of the video image stream, thereby enabling real-time video communication from the local participant to the second participant.

摘要： An arrangement for configuring a reconfigurable system having a plurality of resources includes a compiler that configures the resources to implement a functional system in accordance with a user design. A defect database is also provided that (1) stores information indicating which of the resources is defective when the resources contain at least one defective resource, and (2) supplies the information to the compiler such that the compiler does not use the defective resource when the compiler configures the resources to implement the user design. The arrangement also includes a detection subsystem that repeatedly and redundantly tests operational condition of the resources grouped in different groups to detect the defective resources.
