STUDY OF OPTIMIZATION OF COOPERATIVE MOTION BETWEEN TWO PERSONS BY MUTUAL TRACKING EXPERIMENTS

摘要

Among the non-verbal communication, mutual motion is the simplest and easiest to study experimentally and analytically. We studied communication dynamics by performing mutual hand tracking experiments, and revealed how prediction mechanism functioned in cooperative motion of human. A series of mutual tracking experiments verified; (1) When the speed of the process is slow, motional communication demonstrates the changing of the subjectivity between the two persons. (2) When the speed of the process is high, optimization of cooperative motion for the motional communication is realized by creating a common rhythm, whenever possible, and thereby reducing the fluctuation of the relative position error between two persons.
