Virtual space teleconferencing system

Describes a virtual space teleconferencing system which realizes communication with realistic sensations. Real-time reproduction of a 3D human image is realized by this experimental system, which ATR recently built for the realization of virtual space teleconferencing in which participants at different sites can feel as if they are at one site and can work cooperatively. In the teleconferencing system, the 3D model of a participant is constructed by a wireframe model mapped by color texture, and is displayed on the 3D screen at the receiving site. Promising results for real-time cooperative work using the experimental system are demonstrated. This system is an application of multimedia technology. In this paper, a higher level of interaction is described that allows verbal instructions to be combined with 3D input devices for generating, manipulating or modifying 3D virtual objects.
