The most popular, and cheapest, teleconferencing systems are those based upon a PC and use the Internet as the data communications medium. Advanced system may use specially constructed and designed rooms, large screen projection systems and communications networks. While such systems are undoubtedly useful, they are not realistic enough to enable the participants to believe that the person they are talking to may actually be in their presence. There are a number of physiological factors that are lacking in such teleconferencing systems which detract from the realism of the experience. These factors include: (1) Low resolution images. (2) Images not to scale. (3) Transmission delays discernable in the images being viewed. (4) Images are in 2D and therefore not perceived as being life like. (5) Images are seen from a single perspective and do not alter as the viewers head is moved. (6) It is not possible for the participants to obtain eye contact. While factors 1, 2 and 3 can be addressed with careful construction and system design, factors 4, 5 and 6 are more difficult to overcome. An autostereoscopic teleconferencing system will be described that overcomes all the factors addressed above and provides a highly realistic viewing experience for the teleconferencing participants.
