動作困難性と必要提示部位の人の動作模倣への関連性の検証と実験手法 Evaluation and Experimental Method for Relevance of Difficulties of Actions and Essential Body Parts to Motion Imitation
In this paper, the effects and the experimental method of difficulties of actions and the essential body parts provided on observing and imitating actions are discussed. Difficulties of actions are represented by complexity of postures, power, and difficulties of expression of the subject toward the observed actions. The body parts are represented by the number of end points shown to the subject. An experiment on imitating daily life actions was conducted. Many kinds of short actions according to the difficulties of actions were displayed to the subjects. The number of displayed human figures' body parts was changed for each action. After observing each action, the subjects imitated the observed action. The imitated actions were monitored by the mechanical motion capture. Similarities between the imitated and displayed actions are evaluated by using DP matching. If these actions are similar, the subject is thought to succeed to imitate the displayed action. The result shows that (1) imitation becomes difficult with the increase of complexity of posture, (2) power of action has weak effects on imitation, (3) the increase in displaying body parts does not necessarily improve the subject's success rate of imitation, and (4) the decrease in difficulties for expression does not improve imitation.
