Dynamic Split Body: Changing Body Perception and Self-Location by Manipulating Half-Body Position

Some studies have been conducted to induce the sense of being in two locations by inducing body ownership in two bodies. However, the feeling of being in two locations was weak. In our previous study, we induced body ownership in a split avatar in advance to induce the sensation of being at two locations. As a result, although participants’ self-location extended to the right, the split avatar was perceived as a single body and they did not feel as if they were in two locations. Our demonstration expand our previous work by allowing participants to dynamically manipulate the position of the split body. We attempt to present an experience in which the split body is perceived as one body even though it is split, or the participants feel as if they are in two locations as two independent bodies. We also changed tracking system from OptiTrack to Lighthouse.
