DOACOM: Video Chat System with Door-Type Interface

In recent years, the use of free video chat systems has become very common. However, the problem of telepresence exists in a video chat. To solve this problem, we developed a new video chat system called DOACOM that uses a door-type interface. We tried improvement of the present video chat by exceeding the frame of a display. The paper presents the system configuration of DOACOM and the performance evaluation of the system. We conducted experiments using a door-type interface and a mouse interface. We obtained the following findings: (1) A door-type interface improves the other user´s presence in a remote place. (2) We were not able to verify the effect that provided the feeling of being in the same room. However, we verified the possibility of providing this feeling by using the door-type interface. (3) A door-type interface realizes higher operability than a mouse interface.
