Room-sized immersive projection display for tele-immersion environment

Although an immersive projection display provides a high quality of presence, it requires a large space and a high cost to equip the facility. This paper proposes a room-sized immersive projection display system named CC Room. In this system, the rounded corner of an ordinary room was used for the screen, and the projectors equipped with the fish-eye lenses were used to project wide angle images. By using this system, an immersive virtual environment that covers the user's view can be generated using one PC and one projector system. This system was connected to the JGN2 network and it was applied to the tele-immersive communication using video avatar. This paper describes the system construction of the CC Room, the distortion correction method, the evaluation experiments and the tele-immersion applications.
