Do We Have to Look at the Mirror All the Time? Effect of Partial Visuomotor Feedback on Body Ownership of a Virtual Human Tail
Ryota Ito, Nami Ogawa, Takuji Narumi, Michitaka Hirose · 2019
Studies have shown that the sense of body ownership towards virtual humanoid avatars with additional body parts can be successfully elicited when synchronous visuomotor and/or visuotactile feedback is given. In an interactive virtual reality (VR) application, however, it is difficult for users to uninterruptedly observe the added body parts, especially when they are attached to the backs of the avatars. Thus, the embodiment of such body parts needs to be achieved using limited synchronous visuomotor feedback. Commonly, it is specifically done by looking at a virtual mirror reflection of the avatar’s movement. However, the methodology of eliciting the sense of body ownership in such conditions remains to be studied.
