Outline of Research at the Start

触れることによって素材の種類が判別できる原理(素材触知覚の恒常性)は全く謎である.本研究は,触感ディスプレイによって自在に統制される触覚刺激群を用いて,この原理に関する仮説を検証する.仮説は,知覚次元(表面粗さ,摩擦などの知覚)間の刺激強度の共分散を活用して素材の識別が行われている,というものであり,迅速かつ堅牢な素材識別が実現する理由を説明し得る.仮説検証には,申請者らのグループのみが開発している粗さと摩擦刺激を提示可能な表面触感ディスプレイを用いる.この触感ディスプレイは,産業への貢献も高い.表面触感ディスプレイはタッチパネルとの相性に優れ,その高度化の影響範囲は広い.

Outline of Final Research Achievements

Texture is generally defined by friction and surface roughness. The distinguishing feature of our research is the realization of highly realistic haptic feedback using a two-dimensional tactile display that can present both electrostatic friction stimuli and mechanical vibration stimuli.
The first goal is to demonstrate that the two-dimensional haptic display is superior to conventional displays that present only friction or mechanical vibration stimuli. We showed, through participant experiments, that the combination of friction and vibration stimuli is more appropriate.
The second goal is to integrate the two main texture generation algorithms at the time of our research or its commencement: 1) physical model type and 2) statistical model type. The integrated model provided a superior haptic experience compared to the physical model type.

Academic Significance and Societal Importance of the Research Achievements

タッチパネルは現在の情報機器にとって,もっとも標準的なヒューマン・インタフェースである.われわれの研究は,ここに触覚刺激提示機能を付加するものであり,より直感的で楽しいインタフェースの実現につながることが,多くの研究によって実証されている.本研究は,テクスチャ提示に焦点を絞り,その最高峰の提示装置と刺激生成手法の開発を同時に推し進めるものであり,ここで確立された技術は,やがて普及する技術の礎となる.
