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.
