Provision of a overlay
Complete Overlay Design
The user interface is enhanced by designing a unique membrane overlay.
If the adhesive allows, the overlay may be heated and removed (supporting the hackability requirement.)
The graphic design is silkscreen printed, reducing color choice (a cost constraint) and obstructing gradients.
The material choice is 250μm (micrometers) polycarbonate with a 250μm peeled adhesive layer.
