非同期型追体験システムの身体所有感と動作の主体感に対する振動刺激と追従動作の効果

抄録

A physical reliving experience system for craftsmanship can be useful in sales promotion and training. In particular, an asynchronous system that incorporates videos can be employed for sharing the experience with multiple users at a low cost. However, the users of such a system cannot acquire a sense of ownership and agency. Hence, in this study, we propose a system that creates an illusory sense of ownership and agency by presenting vibration stimuli that are synchronized with the video and by following the user’s hand movement to the corresponding video motion. The obtained results indicate that the proposed system improves the user’s sense of ownership and agency. Furthermore, sense of ownership and agency improve when the same motion is repeated, even if there is a discrepancy between the video and user’s hand motion.
