| Outline of Final Research Achievements |
A passive-type control devise is developed using Mechatronic technology with a VR system to investigate muscle kinesthetic sense properties in manual operations by fast hand motion, such as a virtual hitting-ball task. A human operator wears a VR-HMD and maneuvers the shifting lever of the passive-type control devise, so that he can hit a ball with the racket in the VR space. He/she receives an impact force at the time of ball-hitting. Operational experiments were then carried out to investigate the relationship between the reaction force patterns designed for ball-impact and the subjective evaluations according to the ball-impact forces. A set of experimental results demonstrated that the onset time of reaction force is more important for providing a natural ball-impact force in the hitting-ball task by fast hand motion.

| Academic Significance and Societal Importance of the Research Achievements |
速度を高めた操縦動作によるボール・インパクト感の知覚作業では，反力負荷の継続時間の変化よりもタイミングの変化に対して，敏感に反応することを明らかにすることができた．このことを踏まえて，反力負荷に対する知覚能力の測定・検査や，ＶＲを活用した上肢運動リハビリテーションにおける反力負荷のアレンジに役立つと考える．そしてまた，自動車ステアリングによる運転ドライバー支援システムの設計・評価にも展開できるものと考える．
