Abstract
Because velvet hand illusion (VHI) induces the tactile sensation of velvet cloth, we utilized VHI to create a new haptic virtual reality. In this study, we performed a series of psychophysical experiments to evaluate whether VHI can be generated in a tactile display. Our results determined that, since the ratio of (stroke r)/(line distance D) is proportional to the VHI strength, it is possible to control VHI strength in the range of r/D = 0.5 to 1.5 by varying r/D.
