Self-Motion Sensation Affected by Vertical Acceleration and Visual Stimulation

Abstract

The sensation of self-motion is elicited by vision, vestibular sensation, and somato-sensation.We psychophysically investigated the sensation of self-motion affected by vertically moving visual and accelerative stimuli, using a PC-controlled elevator and a head-mounted display.We found from the experimental results that the vertical sensation of self-motion is synergically enhanced by vertically moving visual and accelerative stimuli, when moving visual stimuli, eliciting vection, such as landscape images and images with fixation visual targets, are presented.
