Outline of Final Research Achievements

Effects of pictorial and scenic attributes on visually induced self-motion perception (vection) were investigated by psychophysical experiments employing visual stimulus which can be assumed as equivalent with retinal image flow under natural self-motion situation (real world image). In vection experiments, 1) observer’s impression against the visual stimulus were tried to manipulate while motion components contained in the stimulus was kept identical, by applying “miniaturization” based on image processing techniques. 2) Motion information were also tried to be extracted from the visual inducer independently of visual displacement, by using a kind of apparent motion phenomenon (2 stroke and 4 stroke apparent motions). Results acquired from psychophysical experiments clearly indicated that vection strength is determined strictly by motion component contained in the visual inducer, irrelevant to the scenic meaning or the visual impression.
