Measurement of wind direction perception by the entire head

In many cases, when we present a video to users, we present sound too. Hence, the senses of sight and hearing are stimulated, improving the users' sensation of presence. In addition, recently, several virtual reality systems using wind have been built to enhance this sense of presence. If we use wind, users do not need to use additional devices for sensing presence because in such cases, we can present them with non-contact sensations. Therefore, wind-based systems do not hamper an improvement in the sense of presence. In fact, some studies have concluded that presenting wind and video simultaneously improves the sense of presence. However, in these studies, wind sources were arranged rather sparsely. In this sparse arrangement, we are not sure whether a precise environment can be reproduced. Therefore, we have examined the perception of wind direction by the entire head.
