01 / Overview

The exhibit presents a unique visual experience to visitors through mechanical interaction.

02 / How visitors use it

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.

03 / The science behind it

The exhibit mainly consists of two adjustable lenses, three white baffles, and a light source. Please have a friend sit as your model in a chair across from you and keep it still. Move the lens to either end (left or right), place the forehead in front of the metal plate with two peepholes, and look straight ahead from the holes without moving the line of sight; At this point, one eye sees your friend, while the other eye sees a white panel (mirror reflection). Next, place your hand on the white panel on the left (right) side and continue to look straight ahead. Try to slowly move up and down with your left (right) hand, and you will notice that your friend's face becomes faintly visible as your hand swings.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
