Description

Though the retinal image terribly changes with the movement of our head or eyes, our perceptual world is stable. It is called position constancy or visual stability. When we observe a virtual-reality environment through a head-mounted display with moving our head, the perceptual world is stabilized by the appropriate visual/motor gain without significant system delay. It is known that the position constancy adaptively changes for a manipulated gain. We aimed to test generality of the visuo-motor adaptation. We found that the visuo-motor adaptation occurred irrespective of the amount of visual information or active/passive movement. Even though the eye for adapting and that for test were different, the adaptation was intact. Thus, the visual-motor adaptation for visual stability is concerned with relatively higher information processing, at least after the fusion of binocular sources.
