| Outline of Final Research Achievements |
We 1）constructed an omnidirectional ultra-high resolution multi-viewpoint multiple-exposure image measurement system with a pixel of 3.45 μm, 2) proposed a method of classifying the materials from BTF of the target material, and a method of estimating the friction force of metal and rigid body material harder than human fingertips, 3) developed a device to measure the aspect of contact traced with a fingertip and proposed a method to estimate the friction force of deformable material from the acquired true contact area, 4) proposed a method for estimating the bending rigidity based on the correlation between the bending of the yarn of the fabric and the bending rigidity and showed the possibility of estimating the friction force from the visual texture information.
We 5) constructed a human fingertip simulator (deformation model) and a tactile simulation that presents the stick-slip phenomenon during tactile sensation.

| Academic Significance and Societal Importance of the Research Achievements |
触感の提示は視覚的質感認知を向上させることが報告されているが,織物のように複雑な表面微小構造と複雑な光学特性と変形特性をもつ物体の,視覚的質感情報のみから数マイクロメートルスケールの触覚的質感情報を抽出する研究は未だ報告されておらず，極めて挑戦的な研究である．
本研究課題が達成されれば，質感表現や質感再現技術を進展させ，有形無形文化財などのデジタル視触覚展示や体験学習を実現する．また，触覚通信に応用されれば，3)触知感と質感を提供する触覚通信が実現され情報通信技術の概念が一変し，遠隔医療や娯楽，通信販売など様々な分野で応用が大きく進展する．
