機械を用いてスポーツや身体的技芸などの動作を学習者に教示する方法を比較した.教示法は,従来の①Indicate:運動非惹起刺激による随意運動の示唆,④Enforce:強い外力での不随意運動の強制,提案法に加え,提案の②Induce (trigger):弱い外力による随意運動の誘発.提案法③Cooperate:中ぐらいの外力と随意運動とで運動に必要なパワーを分担する共動である.
特性関与因子は,(a)人と機械のパワー動員比,(b)ヒトが動員する感覚,(c)誤差フィードバックの有無と態様,(d)筋活性因子,(e)運動主体感因子など,動作教示特性は動作再現性能や動作学習効率などとした.
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.
