Abstract
It was shown that the self-motion perception (i.e., vection) with cutaneous inputs was influenced by the “change” (with or without) of the wind intensity which is applied to the participants’ face.(Murata et al., 2015). The present study aimed to investigate whether the change of the cutaneous intensity (“approaching to” or “leaving from” the wind source) would also influence the vection. The former condition is that the source itself was moved to the participant sitting on an aero bike (which is placed on a board). The latter condition is that the source was moved away from the participant. In both conditions, the wind intensity was manipulated by continuously changing the distance from the source to the face. A constant vibration was applied to the participants via the board in such a way that the participants received simulated vestibular stimulations. The latency and duration were measured as indices of the vection. The result showed that the vection appeared to be faster in the “leaving” condition compared to the “approaching” condition.
