In this research, we combined the virtual reality technology and the tale-immersion technology, and constructed the prototype system of fusion reality that combining a virtual space and a real space. Moreover, we were able to clarify the effectiveness of this research. In this research, we constructed the fusion reality environment that used video avatar by background differencing technique, and achieved the shared space where remote users are able to collaborative working on ultrahigh-speed network. Moreover, the high resolution immersive presentation system was achieved by using not Caves and Immerse Desks of high denomination but low-cost Tiled Display systems, and we adopted the operation interface that was able to be operated intuitively. In addition, it was difficult in existing researches to load various object formats constructed with variety of modeling software to the shared space. Then, this system achieved the prototype system corresponding to various object formats. In this paper, the extension method of the virtual reality technology and the extension method of the high realistic sensations communication system were defined, and we established the high realistic sensation system by the new fusion technology with real space and virtual space.
