抄録

We built an acoustical telepresence robot named TeleHead. TeleHead has a user-like dummy head and is synchronized with the user's head movement in real time. The user-like dummy head improves sound localization accuracy. However, making the user-like dummy head for all users is not realistic from the viewpoint of engineering. Therefore, we make several kinds of simplified dummy head and make sure of their influence on sound localization. The results show that the user-like dummy head is the best dummy head for sound localization experiments. Ball-like dummy heads with user-like pinna make second-best results. When using a simple ball-like dummy head, participants cannot localize sound at all. It suggests that accurate dummy head improves sound localization accuracy. On the other hand, there is a possibility of simplification of dummy head at the point of sound localization for the users.
