queue marching

The exhibits display the small character models in a queue through electromechanical interaction, allowing visitors to understand that it is actually utilizing the phenomenon of visual persistence of the human eye.

Interaction type: Electromechanical, hands-on. 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.

The exhibit consists mainly of handwheels, turntables, miniature models, strobe lights, etc. When participating, visitors rotates the handwheel, the strobe light lights up, the turntable rotates, and the miniature model also moves accordingly. With the cooperation of strobe lights, visitors can see the original static small character model presenting continuous moving images. Experimental results have shown that if a scene is repeatedly presented with intermittent brightness, as long as the repetition frequency is greater than 7 times per second, the impression of the existence of the scene will be retained. This repetition frequency is called the fusion frequency. A movie is the rapid movement of still images (24 frames per second).
