Abstract
We investigated how visual and haptic information was integrated when the position of the real hand was inconsistent with that of mirror image of the rubber hand. Participants placed their left hand behind the mirror placed between their arms, and observed the rubber right hand through the mirror. When the positions of the real and rubber hands were consistent, participants experienced haptic perception in the location that was visually stimulated by the red laser-light. When their positions were inconsistent, they still experienced haptic perception in the location that was visually stimulated by the laser-light. For example, participants experienced a strange feeling that they felt touched on the palm of the fifth finger while the back of the first finger of the rubber hand was stimulated by the laser-light. These results suggest that the haptic information is integrated with the visual information of the spatial locations.
