Abstract
In this paper, we propose a method to increase vection strength through video image processing in the periphery, rather than the center, of the visual field. Specifically, we propose two methods. One is an image stretching process in the visual periphery and the other is an alpha-blending process with an expanding circle grating in the periphery of the field. We clarified the relationship between the processing conditions and vection strength and found that stretching in the left–right direction increased vection strength while stretching in the downward direction did not. When adding expanding grating by alpha-blending, vection strength and duration were increased in almost all cases.
