Outline of Final Research Achievements |
In this study, I developed a device using the haptic illusion phenomenon called the "hanger reflex" to provide haptic feedback in virtual reality experiences involving whole-body movements. This phenomenon presents the perception of haptic feedback by inducing shear deformation of the skin. It has been previously observed in the head, wrist, waist, ankle, and knee. As a result of this study, I confirmed that a similar phenomenon occurs in the elbow. Furthermore, I developed a device that can simultaneously provide hanger reflex stimulation to a maximum of seven locations, including the head, elbow, wrist, and knee, which were previously only stimulated at one location. I conducted a perceptual haptic characterization study when simultaneously stimulating multiple locations using the developed device.

Academic Significance and Societal Importance of the Research Achievements |
一般的に身体の複数部位・自由度の力覚を提示するためには対応する数のアクチュエーターが必要とされ,大型・重量の装置が必要とされてきた.本研究で開発した装置は人間の錯覚を利用しているため,比較的小型・軽量な装置で力覚提示可能となるため使用者の負担を軽減させることができる. 本研究の社会的な意義は,小型・軽量な装置であるため装置の低コストでの実装が可能であるため今後の社会実装による普及が期待できる.本装置はリハビリ時の姿勢・動作支援への応用が期待できるため,より多くの利用者への普及も期待できる.
