Psychological measurement of coupled human balancing tasks

In this paper, we investigate the relationship between human sense and motion in coupled human balancing tasks. We propose a measurement system to obtain the balancing error produced by two human subjects stabilizing a coupled inverted pendulum model in cooperation. After an experiment to measure the balancing error, each subject evaluated the performance of manipulation of both his own self and his partner. The factor analysis on sense and motion of the subjects implied that correlations can be found between the balancing error and the sense of aggressiveness and also between the motion delay and the sense of activity.
