Abstract: In this paper, we propose an innovative videoconferencing system called |IshinDenshin System|, in which the participant|s image and shared workspace are naturally merged. This system proposes an idea to improve the efficiency of conferencing by supporting eye contact and presence of finger pointing. A small video camera is placed at the common point of gaze direction between the display and camera. The transparent-based division is applied. Thus, the participants can use their fingers to indicate any portion as in face-to-face interaction, particularly for indicating shape, size, and direction. The performance of the system has been observed based on the preliminary experiments of an implemented 2-way videoconferencing system. The results prove the merits of the proposed idea in increasing the sense of reality by eye contact and simple user interface of finger pointing.
