Motion-like perception means that under certain time and space conditions, people see the motion between stationary objects, or continuous motion without continuous displacement, that is, they perceive the actually stationary objects as motion, or they see continuous motion without continuous displacement. It's actually a normal illusion. As long as the conditions are met, there will be illusions.
There are four main forms of exercise:
1. Kinematic motion: When two stimuli (light spots, straight lines, figures or pictures) are presented one after another at a certain space interval and time distance, we will see continuous motion from one stimulus to the other, which is called kinematic motion. For example, the common LED screen in today's society is actually composed of a Fang Gezi. The characters displayed above move from left to right or from right to left. In fact, their Fang Gezi does not move, but they are different and glow one after another. When we perceive them, we will perceive them as the continuous movement of words. In fact, this principle is used in cartoons, early movies and neon lights in life.
2. Induced motion: It is called induced motion because the motion of an object gives the impression of motion to an adjacent stationary object. For example, the moon in the night sky is actually relatively static and the cloud is moving, but when people perceive it, they see that the moon is moving and the cloud is static because of the movement of the cloud. In life, there are trees outside the window of the running train, which is rapidly retreating.
3. Autonomous movement: refers to the phenomenon that people look at a weak and static light spot in a dark room and feel the light spot moving back and forth after a while. For example, on a moonless night, when we look up at the sky, we sometimes find a small shiny thing swimming in the sky. We will mistakenly think that it is an airplane, but it is actually an autonomous movement caused by a star. For another example, if you light a cigarette in a dark room and look at this light spot, you will also see that this light spot seems to be moving.
4. Aftereffect of motion: After watching an object moving in one direction, if you turn your eyes to a stationary object, you will see that the stationary object seems to move in the opposite direction. For example, if you look at a certain part of a waterfall and then look at the still mountains, trees or fields around you, you will feel that they are soaring upwards. After watching the speeding train, you will feel that the nearby trees are moving in the opposite direction.
