Galvanic sight stimulation (GSS) is a lightweight and wide-viewing-angle visual information presentation method. In the GSS method, electrodes are placed on the skin around the eyeball to perform noninvasive electrical stimulation, thereby causing a white flash called phosphene. While the viewing angle of a head-mounted display is a maximum of approximately 110°, the extent to which the GSS can present visual information is not known. In this study, we demon-strate the advantages and usefulness of GSS via the quantitative measurement of viewing angle that can be visually presented by GSS, and a comparison with the viewing angle of the existing optical visual presentation method.
