Motion of an object can be estimated from its shape and/or bodily action even when the object remains stationary on the retina. In addition, such an object-based motion signal induces motion appearance in the background image. These phenomena show that our perceptual system produces dynamic mental representation independent of retinal motion signals. Here I review studies about the object-centered motion perception, and I discuss underling mechanisms and relevance to real-world situations.
