Abstract

The wallpaper illusion, first described over a century ago, can occur when a person with normal binocular vision views a pattern that is periodic in the horizontal meridian of the visual field. Escalator trends present such a pattern. Evidence is presented favoring the view that disorientation experienced by escalator riders is caused by this illusion. Possibly some of the estimated 60,000 escalator falls occurring in the United States each year are linked to it.

摘要

壁纸错觉在一个多世纪前首次被描述，当具有正常双眼视觉的人观看在视野水平子午线上呈周期性的图案时，就可能会出现这种错觉。自动扶梯的梯级走势就呈现出这样一种图案。有证据支持这样一种观点，即自动扶梯乘客所经历的迷失方向是由这种错觉引起的。在美国，每年估计有6万起自动扶梯摔倒事件，其中可能有一些与此有关。
