Abstract (in Japanese) (See Japanese page) 
(in English) t-Room has attracted a great deal of attention as an assistant system for remote collaboration. It consists of a variety of audiovisual equipment and computers, and it increases the "sense of being in the same room," i.e., a sense of co-presence, by creating media symmetry between distant t-Rooms. To do this, t-Room employs unusual settings of camera and display, where a shot image is iteratively fed-back between a camera and its counterpart display. Obviously, the image feedback, i.e., visual echo, disrupts smooth visual communication, and this problem must be solved. To this end, we investigate the properties of a recent, image-differencing-based echo cancelation method for image feedback.
