Galvanic vestibular stimulation (GVS) induces a sensation of virtual acceleration as vestibular information and affects subject's field of view. In particular, GVS with alternating current (AC) causes roll rotation centering on the direction of a look in subject's vision and it is showed that this phenomenon originates eye movement induced by GVS in the past researches. The purpose of this study was to show the quantitive relation between the amount of stimulus current and the angle of subjective tilt of the visual field. In order to achieve the purpose, we displayed a straight line canceling the subject's tilt and measured that amplitude and time delay from stimulus current.
