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. (c) 2007 Elsevier B.V. All rights reserved.
