In this study, we focus on solving the problem of gaze presentation in telepresence robots with a rotatable display that causes lack of presence or low participation of remote participants. As a role that gaze should play, we focus on "mutual gaze" and "joint attention" and present a system to fulfill these roles. We implemented a new telepresence robot system which used the humanoid head as a physical pointer, and conducted two experiments. Results of these experiments reveal that the proposed system with humanoid head can increase the accuracy of gaze direction estimation, and also improve sense of “being looked at”, “co-presence”, and “face to face”. Furthermore, the mutual gaze is accomplished more often with humanoid head. The results also reveal that not only proposed system but also the system with display rotation are effective to guide participant’s attention and improve impression of joint attention.
