Our previous work has demonstrated that rubber hand illusion (RHI) can be elicited under active self-touch, in which participants can stimulate both their own hand and a rubber hand by using a master-slave system. This paper, in particular, discusses force feedback effect on the RHI under such unique condition. In our RHI paradigm, the participants give haptic stimulations such as tapping and stroking their hand and the fake hand. In this condition, if the tapping force on the fake hand and the contact force on the real hand have large difference, the participants might have strange feeling and would not experience the RHI; we assume that the force feedback plays an important role to determine our body ownership. Then, this paper examines how the force feedback affects the RHI under the active self-touch by changing the magnitude of force rendering on the master device.
