| Outline of Final Research Achievements |
Visually-induced motion sickness might be caused by intermittent disagreements between the lens accommodation and vergence. In this study, subjects viewed video clips composed of two-dimensional/three-dimensional images in which a sphere was made to ambulate complexly. The subjects viewed clips where the peripheral images (PIs) were removed and clips with/without perspective clues (PCs) in addition to the originals. Our studies confirmed that the influence of visual recognition of stereoscopic images without PIs and PCs was considerably lesser compared to the originals that caused unpleasant symptoms in previous studies. The subjects’viewpoints were moved around wherever they wished, so that they viewed the objects sequentially from different viewing distances. Interactions occurred each time between the bio-system to control the lens accommodation and vergence in human. These systems cannot be described by stationary processes, and the body should be loaded by a nonequilibrium state.
