There are two mechanisms of visual attention, which have different developmental processes. One is passive bottom-up attention and the other is active top-down attention. LED guide lights attract attention by the movement of light. Although such a bottom-up attention-grabbing display is intuitive, it has a disadvantage for constant use. In this study, we focused on the attention-inducing effect of the motion illusion to induce the illusion of motion in still images. The purpose of this study was to propose a display with high attention-getting effect by incorporating optical illusions. In this study, we used an illusory image of moving gratings to give the illusion of motion by placing black and white gratings in front of a gray background. To investigate the attention-inducing effects of illusory images, we conducted a visual search task with stimuli of illusory images that were not related to the task. In the visual search task, we tested whether the target in the upright disturbance was tilted to the left or right. As a result, we found that the optical illusion reduced the reaction time when guiding attention to the target. In addition, we measured the number of eye movements during the task and analyzed the number of gazes by using a gaze-measuring device. As a result, we found that the number of gazes decreased when the illusion induced the target's attention. The results suggest that the motion-induced optical illusion induces visual attention.
