Popis:	We built an acoustical telepresence robot, TeleHead, which has a user-like dummy head and is synchronized with the user’s head movement in real time. We are trying to clarify the effects of reproducing head movement. In this paper, we evaluate the sense of incongruity induced by the delay time in reproducing head movement. The results indicate that whether users feel the delay or not depends on their spatial perception. Therefore, acceptable delay time can be calculated from the user’s localization accuracy and head movement speed. Even under the strictest condition, i.e. high-speed head movements, using white noise makes it easier to localize sounds and roughly about 40-ms delay may be acceptable. Moreover, in conversational situations, 80-ms delay is acceptable.
