Stepping Feet Illusion

Abstract

Perception of motion is affected by the contrast between the moving object and the background. When the background has black and white stripes the contrast changes from one stripe to the next. A dark object will have high contrast against the white stripe and low contrast against the black stripe. The opposite is true for a light object. As a result a motion with constant speed may appear to speed up and slow down. We will show this by using black and white stripes and two moving objects, one dark (a dark blue) and one light (a pale yellow). The program also shows that we can have two controllers one on top of the other on the screen.
