| Outline of Final Research Achievements |
In this study, we developed a measurement system (using two high-speed cameras) that can observe the Stick-Slip phenomenon that occurs on the human finger pad (with a complex surface and anatomical structure) while tracing rough surfaces (periodic gratings), and at the same time, can also observe the situation when the finger pad sinks into groove parts of the surfaces. We also developed and implemented a deformation and contact simulation method that enables fast computation of the simulation model.

| Academic Significance and Societal Importance of the Research Achievements |
実世界では，手と対象物との触覚を伴う様々なインタラクションが発生する．例として，手術，触診・按摩，嚥下，陶芸，製菓等があげられる．本研究の基盤技術が確立され，精緻な柔軟手シミュレータが実現すれば，医療や，伝統工芸，遠隔ショッピングなどの様々な分野への応用が期待される．また，ヒトの触覚の知覚メカニズムはまだ完全には解明されていない．本研究にて指の計測・モデル化を進める過程で得られる知見により，メカニズム解明の一助となることが期待できる．
