Multi-electrodes Galvanic Sight Stimulation shifts position of phosphene

Abstract

Galvanic Sight Stimulation (GSS), of which electrodes are attached on the head skin near the eyes, induces white flash sensation. This visual sensation is named phosphene. Since GSS can induce visual sensation with light weight, reasonable, and small electrical circuit and electrodes only, this technology is an attractive replacement of Head Mounted Display (HMD). To use GSS as HMD, it is required to control the position, strength, shape, and color of the visual sensation induced by GSS. In this work, as the initial stage of the entire study, we demonstrate that the multi-electrode GSS, which we newly invented shifts the position of the phosphene.
