| Outline of Final Research Achievements |
We studied the air control technology to provide stimuli through haptic and olfactory sensations without requiring the user to wear a device. For winds that provide stimuli that are continuous or have a large time constant, we have systematically obtained information by accurately measuring the characteristics of human wind direction perception. Regarding the vortex ring that provides the instantaneous stimulus, we focused on the orbital stability of the vortex ring and conducted experiments mainly with the shape of the opening as a parameter. We found that there is a trade off between the stability and the flying velocity of the vortex ring.

空気をメディアとして利用し，触覚と嗅覚による環境提示を行うための基礎技術を研究した．時定数の長い風による刺激に関しては，人間の風向判別能力を全方向にわたり調査し，正面と背面からに比べて側面からの風の方向がわかりにくいことを明らかにした．短時間の刺激を実現する，空気砲を用いた渦輪による刺激については，軌道安定性と渦輪速度がトレードオフの関係になることを明らかにし，さらなる検討の過程で，空気砲を多数の小開口で構成する新方式を発案した．
