Proposal for tactile sense presentation that combines electrical and mechanical stimulus

This study proposes a combination of electrical and mechanical stimulation as a foundational method to realize a tactile display with a high temporal and spatial resolution. We further confirm the interaction between the electrical and mechanical stimulations. The interaction (1) lowers tactile threshold and (2) reduces the so-called "electrical" sensation. The results of this study may resolve certain practical difficulties with regard to electro-tactile displays
