įull size image 1.4 Random Dot Figures that We Perceived Some Message in It When It Vibrate 3) becomes stronger when vibrated perpendicular to the moving direction of the original illusion. 1.3 Other Examples of Illusions of Which the Optical Illusion Strength Become Strong by Vibration By contrast, opposite results are obtained when the same figure is printed on a paper.Īs these characteristics remain unchanged even if the color of the display and the printed matter is similar, spectral constitution could be more important than the perceived color in these two optical illusions. According to Kitaoka, a positive optical illusion could occur when an optical illusion figure is shown on an liquid crystal display(LCD) but the reverse phenomenon would not occur. Reverse illusion phenomenon is dependent on how the image is presented. Kitaoka suggested that this phenomenon could be related to the Purkinije effect. Conversely, they seem to rotate counterclockwise when observed under dark. Kitaoka reported that color-dependent FraserWilcox optical illusion discs appear rotating clockwise when visualized in peripheral vision under light. However, recent studies revealed that the color-dependent FraserWilcox illusion becomes strong when visualized under dark illumination, such as under a desk. Previous studies showed that the optimized FraserWilcox illusion intensifies when the figure is viewed under bright condition. This phenomenon is also perceived in the case using a manually or mechanically vibrated printed figure in this technique, stroke and frequency cannot be accurately controlled.

When this figure is displayed on the PC display and vibrated with software at several Hz, the illusion becomes strong that most people can perceive it. KeywordsĪs this type of illusion is observed in peripheral vision, some people unfamiliar to it cannot perceive it.

Results showed that the proposed equipment can effectively determine the vibration frequency and stroke in which optical illusions can be recognized. Various optical illusion figures were vibrated using the equipment to determine the relationship of optical illusion strength to the amplitude and frequency of vibration. Therefore, we developed a vibration equipment by using a positive mechanical constraint cam. Vibrating a figure on the PC display by software may be affected by the response time and limited refresh rate of the PC display. It is difficult to control the frequency and amplitude of vibration made by hand precisely. By contrast, the intensity decreases in other types of optical illusion subjected to vibration. Optical illusion intensity substantially increases in a color-dependent FraserWilcox figure vibrated at several Hz. Optical illusions, such as the optimized FraserWilcox figures, are perceived to be moving although they are perfectly still.
