| Outline of Final Research Achievements |
Aiming to realize a new form of haptic presentation, "body-harmonized type," that adapts to the flexibility of the body, which changes dynamically due to muscle tension and relaxation in competitive sports and dance, and can teach quick postural changes and movement with high accuracy, we developed a thin pressure distribution sensor and an adsorption-type sensor fixing part, and conducted slip evaluation using a shear force presentation device. We also evaluated the slip of the sensor using a shear force presentation device.
As a result, pressure detection (less than 5 N), contact position estimation (error less than 10 mm), and suppression of unintentional slippage during guidance were confirmed with a thin sensor of 200 μm thickness, and results for the realization of "body-harmonized" were obtained.

| Academic Significance and Societal Importance of the Research Achievements |
従来、人間情報学分野においてユーザの動作を誘導・教示する身体装着型のハプティクス技術が研究されている。一方、身体が柔軟性を有することから所望の誘導・教示ができないという課題があった。本研究により、筋の緊張・弛緩により動的に変化する身体の柔軟性に適応した誘導・教示の基本となる圧力検出、接触位置推定および滑り抑制の技術が実現し、新たな力触覚提示の形態「身体調和型」の技術および概念が具体化された。本技術および概念は、人の動作を伴う様々な社会的活動において今後活用されることが期待される。
