Outline of Final Research Achievements

Four kinds of machine-based motion instruction methods were examined and compared.
The methods were ①”indicate”; non-force stimuli indicate motions to learners, ②”induce (trigger)”; weak external forces induce learners to move their body parts intentionally,③”cooperate”: both the machine and learner cooperatively move learner’s body parts, and ④”enforce”; external forces enforce passive motions on learners.
The explanatory factors were (a) a power-charge ratio between man and machine, (b) man-employed sensations, (c) with/without error-feedback, (d) with/without muscle activities, and (e) a sense of initiative for motions, and the objective factors, i.e., the motion-instruction performance measures were motion reconstruction accuracies, and motion learning efficiencies.

Academic Significance and Societal Importance of the Research Achievements

従来の動作教示法は，①運動の示唆（ビデオ学習のような，機械が学習者の非運動感覚を介して随意運動を示唆）や，④運動の強制（外殻型パワードスーツのように，機械が大きな力学的パワーを発揮して不随意運動を強制）であった．これに対して，本研究では，新たに②随意運動の誘発（教示システムが弱い力を伝えることで，意識的な運動を学習者に「誘発」させる）や③随意運動の共動（教示システムと学習者が相補的に力を発揮して運動）を提案し，より効率的，効果的な動作教示法の開発に資する．
