| Abstract(in English) | When moving while watching something, humans change not only their eyes but also their postures and gaze at target. In this research, we investigate inter-joint coordination in such motion. We focuse on two simple actions: a rise action and a crouching motion. In order to investigate the cooperation between joints, the subjects wore goggles to restrict the range of view so that they could not move their eyes and look at the target. UCM analysis is used to evaluate motor coordination, and the angle of gaze and the variance of barycentric position are divided into UCM components that do not affect performance variables and ORT components that affect the performance variables. As a result, we confirmed that the cooperation among joints was higher if the subjects were closely watching something compared to the gaze angle in which the subjects were not watching anything. On the other hand, regarding the position of the center of gravity, it was confirmed that the coordination between joints tends to be slightly lowered by watching regardless of whether the viewpoint is fixed or not. |
