Outline of Research at the Start

本研究の目的は,腱振動刺激により生じる運動錯覚の自在な制御を可能にするために振動刺激と運動錯覚の関係を体系化することである.現状では腱振動刺激に対する運動錯覚の知覚特性が十分に解明されていないため,実用的な運動感覚提示手法の確立に至っていない.本研究では腱に加振機の機械的振動刺激を伝達する接触子の大きさに着目し,振動刺激と運動錯覚の関係を詳細に検討する.
体系化により,運動主体の一人称的な運動感覚の伝達という運動学習における本質的な課題を解決する突破口となり,一人称的な運動錯覚による新規運動学習手法の確立に向けた重要な一歩となる.

Outline of Final Research Achievements

Tendon vibration causes illusory movement in human limbs, which is a kinesthetic sensation experienced in the absence of any actual joint movement. This phenomenon can be effectively used to generate kinesthetic sensation, which can solve various problems. However, because of the previously unknown relationship between the stimulus and perceptual characteristics, its implementation is limited. This study investigated the synergetic effect of the contact surface area and the joint angle. Participants were asked to take two subjective evaluations of the vividness and range of extension of their elbow-joint angle. During the illusory motion, both parameters increased with the contact surface area and the flection angle of the elbow joint. Thus, the contact surface area and joint angle had a synergistic effect on the perceptual characteristics of the illusory movement.

Academic Significance and Societal Importance of the Research Achievements

卓越した身体技能の習得は,スポーツや身体表現の分野だけでなく,スキルを要求されるあらゆる分野で避けては通れない.本研究の成果により,運動主体の運動感覚の伝達という運動学習における本質的な課題を解決する突破口となる可能性がある.従来の学習者の試行錯誤に依存する学習手法を脱して,スポーツ,リハビリ,技能伝承などあらゆる運動学習領域に対して新たな方法論の確立に向けた基礎的なデータを取得することができた.また,本研究で得られたデバイスは,バーチャルリアリティやハプティックス等の異分野での運動感覚提示デバイスとして広く波及することも期待される.
