Abstract

A method and system provides a face-to-face video conference. The method and apparatus comprise a conferencing system consisting of a conferencing station defining a predetermined motif, an image system for generating a substantially full scale image of a person at the conferencing station so that participants at the conferencing station feel that any images of persons displayed by the imager at the conferencing station are present and face-to-face. The method comprises the steps of receiving image data at a teleconferencing station, the image data including data corresponding to at least one person, and displaying an image corresponding to the image data at the teleconferencing station so that at least one participant at the teleconferencing station views an image of said at least one person, thereby providing a face-to-face presence environment whereat the image of at least one person appears substantially life size. The teleconferencing method may further include the steps of generating image data corresponding to an image, transmitting at least a portion of the image data corresponding to at least a portion of the image to a teleconferencing station and displaying the portion of the image data at the teleconferencing station during a teleconference.
