In the pre-experiment stage, we analyze the colors and shapes of 135 visual illusions by Kitaoka, a Japanese scholar. The result is referenced in the formal experiment. Formal experiment includes three sub-experiments: Experiment 1 is to discuss the effect of the displacement of disjunctive center on visual illusions' movement; Experiment 2 is to discuss the effect of image layout on visual illusions' movement; Experiment 3 is to discuss the effect of color configuration on visual illusions' movement. Post-experiment stage is a repeat of formal experiment to confirm the results.

前测实验是进行日本学者北冈明佳的135幅错视动态作品之造形与色彩的分析，并将分析结果作为正式实验样本之参考；正式实验分成三个实验进行探讨，实验一在探讨分割点中心的位移对於错视图形在视觉动态上的影响，实验二在探讨图形配置对於错视图形在视觉动态上的影响，实验三在探讨色彩配置对於错视图形在视觉动态上的影响；而后测实验则是将正式实验之实验结果进行再实验，以印证正式实验之结果。
