Abstract:
Gazes and pointing gestures are important in performing collaborative work involving instructions with shared objects. However, in general video conferencing systems, the geometrical consistency of size and positional relationships of remote spaces are not displayed correctly on the display screen. This inhibits the transmissions of gazes and pointing gestures vis-a-vis shared objects. It is thus important to demonstrate how gazes and gestures can be smoothly transmitted by video and develop an advanced system that can do it. We previously proposed a ``MoPaCo'' window interface system that can reproduce a communication partner's space within a display as if the display were a glass window to achieve geometrical consistency between remote spaces. Experiment results demonstrated it enables users to feel the distance between themselves and their conversational partners on video is about the same as in a face-to-face situation and the partner is actually present. We also consider MoPaCo can generate video images that smoothly transmit gazes and pointing gestures; this paper describes experimental tests of the system's effectiveness in doing so. Results suggest MoPaCo allows users to accurately identify target objects as they could under face-to-face conditions through an actual glass window. Results of experiments on conversation quality show MoPaCo facilitates smooth conversation and communication among users and strengthens their memories of the conversations, suggesting the users actively engage in conversation and the system makes a strong impression on them.
