Outline of Final Research Achievements

The purpose of this study is to develop a method to make people feel physical movement without large body movements. In this study, we focused on vibration stimulation and transcutaneous electrical stimulation, which are lightweight and small devices that can be used to create the sensation of movement and motion without large body movements. We conducted basic research on the generation of the illusion of a traction force by partial vibration stimulation of a seat surface as a method to produce the sensation of whole-body movement. We also developed a slider mechanism that can create a state in which a person can move, and a system that can combine this with vibration of the seat surface. The effects of two vibration sources on tendon stimulation and transcutaneous electrical stimulation of the foot were verified by finite element simulation, and the design of a new stimulation method was discussed.

バーチャルリアリティ

Academic Significance and Societal Importance of the Research Achievements

VRのHMDを利用した場合,テレワークでの使用を想定した場合,頭部の運動に伴って視空間が移動し,手に持ったコントローラのアクションによって,手が動く.つまり,身体性を伴った体験が可能となるのである.しかしながら,身体性を伴う体験をもたらす運動に利用できる空間リソースは多くの場合有限であり,十分に身体を動かせるスペースがない場合が多い.そこで,本研究では身体を動かしていないにも拘わらず,身体運動を知覚させることができ,身体運動ディスプレイを開発し,有限の現実空間リソース内で,広大なVR空間で自由に運動した感覚を振動刺激や経皮電気刺激等によってもたらす手法の開発に取り組んだ.
