FTIR Compliant surface fabrication
> Acrylic ‘table’ surface”
provides the structure for the screen, resists pressure/supports weight
> Drafting vellum substrate: two functions:
used as diffusion layer for rear projection video
‘compliant’ surface layer; silicone coated to increase FTIR effect, provides some pressure sensitivity
> Mylar
1. protects the fragile vellum layer
2. reduces friction for finger drags across surface
