Outline of Final Research Achievements

This study is based on the hypothesis that differences depending on physical motions such as the way to hold an object, arm movement, direction of the force and so on, can alter the way how people grip objects. The work is composed of two research subtopics, to elucidate the influence of manipulation by subjective weight perception on human grip motion and to verify its effect on motor function. In first research subtopic, it became clear there were changes in subjective weight perception by using two types cutting processing such like rounded and chamfered edge on the corner of objects. In the second subtopic, we made inspection devices for measuring sensory and motor function and for verifying the effects on motor function. Finally the work concludes with showing how manipulating the subjective weight perception can affect three types of grip motion.
