Abstract

A video conferencing system has a two-way mirror, which is between the observer and the display device, positioned at an angle to reflect a backdrop surface. The backdrop surface, which is further away from the two-way mirror than the image plane of the image display device, appears superimposed in a position behind the image of a person from the remote location. A camera is located in the backdrop at a position along the line of sight of the transmitted image so that a perceived eye contact is achieved. A system is disclosed wherein telepresence systems that are compatible with a pre-defined standard are connected via a network connecting, either directly or via a telepresence operations center, to provide interaction with substantially life-sized images of the remote participant displayed with three-dimensional depth cues in the room setting.
