Outline of Final Research Achievements

The purpose of this study is to integrate the function of " teaching movement by taking hands" into VR skill training, which cannot be done by visual and auditory senses only.Firstly, we developed a smart wear that integrates a MEMS sensor that detects body movements and a vibration motor that provides vibration feedback. Especially, a via-hole interposer structure was developed as a wiring mounting structure on fabric that can withstand low temperatures and expansion. Our structure can withstand expansion and contraction of 30%. Using this structure, we developed a suit that enables sensing and tactile feedback. Secondly, we constructed a sensing and feedback system that works in conjunction with VR images using the developed smart wear and Unity, a VR image software.

Academic Significance and Societal Importance of the Research Achievements

学術的な意義は，VR用にスマートウェア実装構造を開発したことである．特に，ヤング率が大きく異なる材料間での材料力学特性に着目し，曲げや伸縮に強いデバイス実装構造を開発したことである．さらに，衣服に実際にセンサや振動モータを実装し，VR用ウェアを開発した．このウェアは，人の動きにより起こる伸縮に耐える特性を持つため実用的であり，今後トレーニングシステムへの実用化などを通じて社会貢献が可能であると考えられる．
