We can know better about human vision as a result of revealing unknown mechanisms of various visual illusions. Motion illusions are typical illusions those mechanisms have not been clarified; why still images can be seen as if they are moving. In this study, we used arrowhead figure as a basic element of motion illusion patterns. We evaluated recognition of motion illusion on various arrowhead array patterns. We have found that a remarkable rate of observers recognized motion to the arrowhead direction on each pattern. This results suggest us that arrowhead patterns can generally cause motion illusion towards the arrowheads. This result was utilized to explain the strange bi-directional motion recognition on the Fraser-Wilcox illusion pattern.
