Tele-Immersive Collaboration Using High-Resolution Video in Tiled Displays Environment

In tele-communication via WAN, the existence of co- researchers by transmission of a video in real scene is important in order to realize high-presence, and its display by the large-scale screen is effective. However, the video image by wide-area display using a projector and large screen is low-resolution, and sufficient presence is not obtained. In this paper, we constructed the scalable tiled displays environment by two or more LCD panels and tried to display a high-resolution video image on the large-scale display. Moreover, we located an small IEEE1394 camera at the center of tiled displays, and discussed the possibility of remote communication which eye-to-eye contact can realize with each other. From these results, we have showed that the existence of participant and ambiance in remote place realized to display in high-presence on local tiled displays environment, and high-resolution display of hand-written characters on tiled displays have become clearer when compared to DV stream on plasma display. Moreover, we have examined that user's gaze was tendency to face front for tiled displays in the case of center position.
