Most of us remember playing with colorful spinning tops when we were children. Some of us must have wondered why the color of spinning tops are changing when it's rotating. Perhaps it became a hint or cue for some people to get to know optical illusion and how it works.
A common LED display and liquid crystal display express the information on the pixels with color and light. However, this work expresses the information on the pixel with rotation of paper disks. Since the paper disks have patterns to cause an optical illusion, it changes a texture or a color by the binocular rivalry and afterimage effect. This is an effect based on our cognitive characteristic. This work is a display using a physical motion and the cognitive characteristic of human being.
Moreover, since the pixel of this display is rotating physically, it sounds like music. If we get close to it, we feel the wind blowing caused by the rotating pixels. In addition, if a viewer shakes his hand in front of face, the appearance of rotating disks change because frequency of the light which reaches eyes would change.
This work is augmented spinning tops by the computer and an actuator and is the display which hopefully advance and sharpen man's cognitive characteristic.
