What is the falsely perceived motion of oneself called when no physical motion is actually occurring?

The term for the falsely perceived motion of oneself when no actual physical motion is occurring is known as "vection" or "induced motion." This phenomenon occurs when a person perceives themselves as moving because of the motion of surrounding objects, leading to a disconnection between actual motion and perceived motion.

In instances of vection, the visual inputs from the environment create a misleading sense of movement, which can be particularly strong in certain scenarios, such as being in a moving vehicle or observing clouds or other objects moving in the background. This perception can result in confusion or disorientation, especially in aeromedical contexts where flight can exacerbate these feelings.

While 'illusory motion,' 'autokinesis,' and 'optical illusion' are all related concepts involving the perception of motion or visual cues, they either describe broader aspects of visual perception or focus on different phenomena rather than specifically identifying the self-perceived motion described in this question. For example, autokinesis specifically refers to the perception of motion of a stationary point of light in a dark environment, which is a subset of the broader category but not directly what is sought in this question.
