Abstract

An eye contact video conferencing terminal (500) comprises mirrors (521, 522), a directionally transmissive layer (601), i.e. louver assembly, and a camera (530) are positioned with respect to one another such that intimate communication is realized between the parties without substantially reducing the transmissivity of the apparatus. The louver assembly is located in front of the terminal screen and passes an image of the distant party radiated from the terminal screen which is subtantially parallel to the louver assembly. A
first partially silvered mirror (521), reflects the image of the local party and transmits the image of the distant party that is radiated from the terminal screen (125) and passed by the lower assembly. The reflected image of the local party is directed toward a second mirror (522) located below the first mirror, and is positioned to capture the image of the local party from the first mirror and to reflect this image into a miniature camera.
