Motion Perception

Motion perception illustrates the concept that our brain constructs our perceptions. Motion, for instance, is a mere perception of a series of still-images that are interpreted to show change in position. Animation uses such a technique in which still-images are flashed in quick, successive order to give the illusion of motion, here called stroboscopic movement. This idea is illustrated by the images below depicting a series of still-images in which a ball changes position. Should the images be shown in a rapid, successive order, the brain would perceive the changes in the ball’s position to be motion.
