Paper Abstract

A person has a feeling of 'being in' an image when watching a screen with a wide visual field, and his somatic sensation and sense of direction are affected by the image. Making use of this effect, we investigated the sensation of reality in images based on testing the sense of direction. In our studies, we examined the relationship between information as it is perceived by the human visual and vestibular systems. In our experiment, we used images from a horizontally rotated cameras for the visual information, and displayed these imags through a head-mounted display. Also, we set up an angular acceleration using a turntable as information to be perceived by the vestibular system. The direction of rotated cameras and the turntable were separately controlled, and the directions were varied. We found that the human visual system dominates in the case of stimuli which are small which are small for the vestibular system, and overestimates in the case of stimuli which are significant for the vestibular system. The results showed that the visual system is important for the perception of the sensation of reality, which is enhanced if stimuli to the various sensory systems are in correspondence.
