自己身体の認識がVR空間内の運動パフォーマンスに及ぼす影響

抄録

It is still unknown how the viewer perceives the self-body in virtual space. In this study, we investigated the differences in performance of a simple motor task in a virtual space when the visible type of the 3D self-body model was changed to one of three types: “the whole body visible,” “the body partially visible,” or “the body invisible.” The quantitative data of the motor were used to analyze the durations and accelerations of the motor task. The results showed that the duration of the motor task varied depending on the visibility of the body models. The results also suggested that visual body information, particularly the self-body, continuously provides a potential interference to the smoothness and quickness of human motor control.
