A novel wearable device to present localized sensation of wind

We study a wearable device for presenting the sensation of localized wind. Previous works on wind displays used an array of fans that were fixed around the visual display. The distance between the fans and the user was relatively large, making it difficult to give the impression of "local" wind, such as the virtual experience of a bullet passing close to the skin. We propose a local wind display that is a new type of wearable device. The presentation area is around the ears, which the area of the body most sensitive to wind. In this paper, we evaluated the sensation threshold of wind at different parts of the body, focusing on the head. We also measured the two-point discrimination threshold of the most sensitive area on the head. Finally, we propose an application of the device.
