Illusion Spinner

Understand the visual persistence characteristics of the human body through a large optical turntable. The exhibit is designed as a device consisting of multiple discs that can rotate 360 ° and a corresponding number of control buttons. By rotating a large optical disc, the visual persistence characteristics of the human body are displayed. Observe the beautiful patterns produced by the start, pause, and stop of bicycles, pulleys, and gear transmissions, and observe the changes in the patterns. Participants can press any button to control the corresponding disc to start rotating and observe the visual illusion formed by the pattern on the surface of the disc as it rotates rapidly. After a period of time, the disc will automatically stop rotating and return to its original state. Target audience: Full age display format, electromechanical interactive device operation instructions (audience experience) 1 Visitors pedal bicycles and pull pulleys to make the optical turntable rotate; 2. Observe the visual illusion formed by the surface pattern of the disc to understand the visual persistence effect.

Interaction type: Interactive installation. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

1. Visual illusion: The eyes are very peculiar, they help us obtain information from the outside world. The world we see is so colorful, but we cannot completely trust our own eyes. We can see rotation from static shapes and the complementary green color, purple, from a gray background. Being able to see the same two line segments as different lengths, and also being able to identify non-existent shapes from cluttered images. There are many types of visual illusions, currently divided into background illusion, lateral suppression, Mueller's illusion, depth illusion, transparency illusion, visual afterimage, filling illusion, contour illusion, perspective illusion, perceptual blur, camouflage illusion, motion illusion, and other types. Due to the complexity of visual perception, people have different visual illusions at different levels. And optical illusions, mainly geometric shape illusions, are mainly studied in the types of size illusions, shape and direction illusions. 2. When the human eye observes a scene, light signals transmit.
