Viewing angle dependency of visually-induced motion sickness in viewing wide-field images by subjective and autonomic nervous indices

The sensation of presence or the sensation of “being there” when viewing a video system increases as the viewing angle increases. This relationship has driven the development of wide-field imaging systems. However, visually-induced motion sickness has become an important factor when considering such wide-field video image viewing systems. In the present paper, we evaluate the effects of wide-field video image viewing angle by two subjective and two physiological indices. Motion sickness was induced while subjects viewed vibrating images presented on a Super Hi-Vision display. The results showed that motion sickness as evaluated by a simulator sickness questionnaire increased as the horizontal field of view increased. In addition, the autonomic nervous index demonstrated that viewing vibrating sequences activated the sympathetic control of the viewer.
