Changes in Perception of Induced Motion Based on Voluntary Eye Movements in an Attentional Task

Sometimes a static object in video content is perceived to move. This motion illusion has been classified into two types: (1) induced motion and (2) motion capture. The purpose of this paper is to clarify how voluntary eye movements affect perceptions of induced motion and motion capture. By the results of a subjective assessment experiment, it is clarified that induced motion is inhibited by attention in both the horizontal and the vertical directions for reading textual information. It is also clarified that in contrast to induced motion, motion capture is not inhibited by attention. Specifically, motion capture is not inhibited by attention when viewers move their eyes in the same direction as the movement of the background.
