FIGURE I 1.5 Virtual space teleconference.

Teleconferencing service: The images of participants who are at different sites
are taken by camera, transmitted through communication links to a virtual
space, and displayed stereoscopically in the virtual space, where they can
have a meeting and carry out cooperative work as if they were gathered

11.5 shows a scene of the virtual space teleconferencing system developed
by ATR.

VR with actual reality. (Hyper means different dimensions.) In HR, the concepts
of HyperWorld (HW) and coaction fields are introduced. The HW is a seamless
