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.

在本文中，我们提出了一种通过视野外围而不是中心的视频图像处理来增加矢量强度的方法。具体来说，我们提出两种方法。一种是视觉外围的图像拉伸过程，另一种是在视场外围具有扩展圆形光栅的阿尔法混合过程。我们阐明了加工条件和矢量强度之间的关系，发现左右方向拉伸会增加矢量强度，而向下方向拉伸则不会。当通过 alpha 混合添加扩展光栅时，几乎所有情况下矢量强度和持续时间都会增加。
