| Outline of Final Research Achievements |
Force feedback is required to handle objects under virtual environments. A number of force displays have been developed, but most of them are featured with large dimension and complicated mechanism. In this study, force-like sensation, which is elicited by vibration onto fingertips, was employed to develop simple force displays only with simple vibrators. The purposes of this study are to clarify the sensory characteristics and mechanism of the force-like sensation, and to establish a design guideline for human interface devices. It was found that finger muscle activities are affected by the vibration onto fingertips, and that the magnitude of the sensation is equivalent to that of reactive force with push button interfaces. A push button interface, of which reaction was generated by vibration was prototyped and evaluated to confirm the vibration efficiency.

| Academic Significance and Societal Importance of the Research Achievements |
指先振動刺激により生起する指先に力が加わったような感覚、力覚様感覚によって提示可能な力情報を定量的に明らかにし、この現象が筋活動に変化を伴っていると、振動によって押下時の反力の変化を提示できることを明らかにした。これらの成果により、押下型デバイスにおけて簡単な振動子のみで複雑に変化する反力と同等の感覚を操作者へ与えることができ、簡易な構造の力情報を提示するインタフェースデバイスの開発の指針となり、新たな応用が期待される。
