A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

The human visual nerve converts the received light information into bioelectric signals, which are then transmitted to the brain. After receiving information, the brain will transform into the "original scene", presenting what we see in front of us. After the effect of light ends, relevant information will remain in the brain for about 0.1-0.4 seconds. This residual visual phenomenon is called 'afterimage', also known as' visual persistence '. We have created animation using the principle of visual persistence.

02 / How visitors use it

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 / 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.
