Outline of Final Research Achievements

One of the major unresolved questions in human haptic fine surface texture perception is how the human detect the micro surface changes using their fingertip. During the current research project, we addressed this question by developing a new device to observe the real-time fingerprint vibration when one touches the micro surface. We further investigated the relationship between the fingerprint vibration pattern and surface perception. Finally, for the first time, we investigated the columnar organization in the human primary somatosensory cortex (SI) by using advanced high-resolution (0.7mm) fMRI at 7T. We find that human SI is columnar organized with alternating SA and RA columnar preferences. We regard these observations as an essential step towards the understanding of the human haptic micro surface perception.

Academic Significance and Societal Importance of the Research Achievements

日本の工学分野において,「匠の技」と言われる伝統的な技や職人の感は無形な財産であり,それを受け継ぐ若い世代が減りつつあるのが現状である。本研究の実施により,「触覚の物理的特性」,「接触皮膚の動的特性」,「心理的評価特性」及び「脳ネットワーク特性」の関係解析を可能にし,従来までは困難と考えられていた扉を開いて,新しい研究視点を切り拓くことが期待されている。さらに,「匠の技」の科学的理解が進み,情報処理メカニズムが解明できれば,その機能を工学的装置に置き換えることができると考えられ,新たな「匠の技」を保持する概念は意義が大きい。
