| Outline of Final Research Achievements |
We performed psychophysical experiments for three typical examples of tactile illusions (a velvet hand illusion: VHI, a fishbone tactile illusion: FTI, and a lattice tactile illusion: LTI) and brain functional imaging experiments for the VHI.
We supposed that virtual surfaces were produced in an observer's brain when suitable tactile stimuli were presented to observers. The observers feel tactile illusions when virtual-stimulus-surface characteristics do not match with the surface characteristics which the observers expected. We estimated that subjective frictions of the virtual surfaces were important to understand the tactile illusions. We need to pay attention that the subjective frictions are produced by the activities of nervous system and are different from the physical frictions.
