Abstract : A teleconference system for N conferees, N being greater than two, includes at least two separate stations. Each station has N conferee positions, confronting a virtual conference space, and corresponding conferee positions at each station have the same relative locations about the virtual conference space. At least one conferee position at each station is adapted to be occupied by conferee in person. Surrogate conferees, which include a video display, a video camera, and a loudspeaker, occupy each conferee position not adapted to be occupied by a conferee in person. Each video display faces one conferee and displays the image of another conferee at a corresponding position at another station; the loudspeaker reproduces the voice of the other conferee. The video camera forms image signals of the one conferee and couples these signals to the displays device of a surrogate conferee at a conferee position corresponding to the position of the one conferee at the other station. The system includes a shared graphic display systems. A video display device is positioned at the center of the virtual conference space and has a display screen at about the level of a table top.
