Velvety Massage Interface (VMI): Tactile Massage System Applied Velvet Hand Illusion

Velvet Hand Illusion (VHI) is a tactile illusion that generates sensation of soft and smooth feelings. We propose to apply this illusion to develop the novel interface called Velvety Massage Interface (VMI). This system gives realistic sensation of being massaged on surface of sole of foot like reflexology. We conducted an experiment to verify if the VHI is generated to the sole of foot and if the VHI has an effect on the body in order to make a prototype device. It was observed that the device was able to generate VHI automatically and had some reflexology effect. It suggests the possibility that VHI is applied to tactile displays, which generate smooth feeling of massage.
