Previous studies on virtual reality (VR) suggested that the inclusion of wind or air flow in combination with audiovisual information can enhance the sensation of presence. However, the perceptual nature of wind in such a situation remains unknown. Using a VR environment with a head-mounted display, this study examined how observers feel real wind while viewing a fluttering flag or fallen leaves as wind flows in the virtual space. The results demonstrated that the tactile (cutaneous) perception of the intensity of wind varied depending on the virtual wind speed. This visuo-tactile crossmodal effect tended to be stronger for weaker real wind irrespective of the direction incongruence between real and virtual winds. These findings provide new insights into the multisensory nature of wind perception with contributions to the design of an efficient wind display system in VR.
