| Outline of Research at the Start |
本研究は，日常生活などでよく使っている指先を用いた繊細な触動作を計測し，ヒトが触覚情報をどのように受け取り，そして処理しているのかについて解明することを目標とする．
具体的には，示指と拇指を用いて物体をつまみながらこすり合わせて触感を得る動作をつまみ触動作として定義して，布や紙などの薄い物体の触感をどのように得ているかについて明らかにする．

| Outline of Final Research Achievements |
The objective of this study was to develop a system that facilitates the measurement and analysis of tactile actions executed by pinching with the fingertips.
In the first year, a novel fingertip deformation measurement device was developed for the assessment of pinching tactile actions. In the second year, the design of the measurement and fixation components of the fingertip deformation measurement device was optimized, and research was promoted with the objective of enhancing the accuracy of fingertip force estimation using a transfer function model. In the final year of the study, the fingertip force was measured during the process of creating fishing tackle. The differences in movements and fingertip force between skilled and novice individuals were then analyzed.
The capacity to quantitatively assess and model tactile actions, particularly pinching movements, has been demonstrated in the context of skilled individuals' work.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、日常生活や熟練作業に不可欠な「つまみ触動作」に注目し、指先の皮膚感覚と接触状態を同時に計測・解析する技術を開発するものである。学術的には、触覚受容の詳細な仕組みや個人差の要因を明らかにすることで、ヒトの触知覚メカニズムの解明に貢献する。社会的には、美容師や職人などの熟練技能の構造化やアーカイブを可能とし、技術継承やリハビリ支援、触覚提示デバイス開発など多方面への応用が期待される。
