It is known that the visually-induced self motion (vection) is evoked only by the visual informations, and also known that the vestibular information can affect the vection. In this paper, we investigated the effects of the tactile stimulus on the vection latency and strength when the subjects see the visual stimulus. As the results, synchronizing visual and tactile information was not enough to strengthen or acceralate the vection perception. But to give the tactile stimulus, before the visual stimulus was presented, shortened the latency significantly. However there existed the differences between subjects and there were some possibilities that the subject did not perceive the visual stimulus as the same speed.
