ABSTRACT:
A compact teleconferencing eye contact terminal that can be integrated with a multitude of image display devices. Eye contact is achieved between conferees who share similar eye contact terminals by the use of a uniquely configured integral beam-splitter. The beam-splitter is coated over all or part of its surface so that a region acts as a partially-silvered mirror. The beam-splitter is integral to a transparent substrate member that is configured with subtle curves that permit only a portion of its surface, forming the integral beam-splitter, to be angled at or near 45 degrees from the viewing surface of a display screen. By doing so, the angled portion forming the integral beam-splitter is seamlessly suspended in front of the viewing surface without interfering with the viewing. This uniquely configured beam-splitter permits image capturing without the great increase in depth of terminals or loss of display brightness necessitated by prior art eye contact systems employing partially-silvered mirrors.
