We combined a few methods to effectively create the illusion of embodiment and sense of body motion in the framework of the rubber hand illusion. In our experiments, active hand movements and self-stimulation were employed instead of classical passive tactile stimuli applied to still hands. The combination of these conditions effectively created the illusion. Furthermore, we collectively tested the effects of visual stimuli that were accompanied with tactile sensations. Specifically, we observed that when an object associated with tactile sensations was moving around the fake hand, the illusion tended to be more intensively induced than when an object that was unlikely to be associated with tactile sensations was placed still near the fake hand.
