The employment of Virtual Reality (VR) in medical rehabilitation has been broadened to incorporate visual and tactile feedback, while how people use tangible objects to induce better perceptions in VR remains unexplored. We investigated how partial visuotactile feedback influences users' embodiment and proposed a design idea named TacPoint (a red point mark) that connects to the physical and virtual worlds. The results reported that higher embodiment illusions could be induced in the TacPoint session than in others without feedback during virtual interactions. It is proposed that TacPoint could help people induce the embodiment easily to increase their positive experience in VR rehabilitation training.
