What does induced motion refer to?

Induced motion refers to the illusion of movement in a still object as a result of the movement of surrounding objects. When a stationary object appears to move due to the motion of its background, it creates a perceptual effect where the viewer's focus on the stationary object leads them to perceive it as being in motion. This phenomenon can occur in various contexts, such as when viewing the night sky where clouds move past stars, giving the impression that the stars are moving.

This understanding highlights the complexity of visual perception, illustrating how our perception of motion is not solely dependent on the actual movement of objects but is also significantly influenced by the context and background elements in the environment.
