Conditions influencing perception of wind direction by the head

Recently, several virtual reality (VR) systems using wind have been built to enhance the user's sense of presence. If wind is used, users need not use additional devices, and some studies have concluded that using wind and presenting a video simultaneously improves this sense of presence. In these studies, however, wind sources were sparsely arranged; with such an arrangement, it is unclear whether an accurate environment was reproduced. A number of variables including gender, age, and the facial hit rate may affect the perception of wind direction. In the proposed study, we have examined the effect of these variables on perception of wind direction by the head.
