Presence expression using eye robot for computer go and system

Friendly user interface is desired for robots and computer systems which support human in all areas of daily life, e.g., information service, educational system, support service for elderly, etc.. Presence expressions by eye robot is proposed, where the eye robot expressions help human to more deeply understand robot, and then effectively provide their service in its situation e.g., a personal learning program and an entertainment program. The proposed presence expression is applied a personal education system that involves the eye robot, learning contents on a laptop PC with a web camera, a wii remote (Nintendo Co.,Ltd.) for measuring attention span of a subject based on 3D accelerometer information. To estimate effects of presence expression by the eye robot, subjective questioner is performed in the personal education system. Three type of leaning programs are conducted by the system for 10 subjects with subjective questionnaires evaluated with the 3-poin scale. The results show that the proposed expressions by the eye robot help the subject to feel like one is watching and to have an uncanny impression. As a result, the system has enabled the subjects to take the program with feeling of tension. This research plans to apply computer go system, another personal educational and entertainment system, where the system realizes casual communication in the games.
