We built an acoustical telepresence robot, called <I>TeleHead</I>, which has a user-like dummy head (i.e., the shape of the dummy head and that of the user is very alike) and whose movement is synchronized with the users head movement in real time. We are trying to clarify the effects of reproducing the users head movement. In this article, we evaluated the sense of incongruity caused by the delay time of reproducing head movement by means a psychophysical approach. Discrimination tasks for head-movement delay clarified the users perceptual thresholds against the dead time. The results indicate that head-movement control should have a dead time shorter than 28 [ms] . In addition, this dead time does not depend on the characteristics of an acoustical telepresence robot.
