DSI Rebuild of a DI Table – Motivation

on October 13, 2009 in DSI, Mult-Touch - Interactive Surface Computing

Tim Roth explained a technique that is currently known as DSI (Diffused Surface Illumination) and promises for finger tracking and fiducial tracking at the same time. This approach offers benefits of the rear DI (Rear Diffused Illumination) technique and establishes even illumination distributed over the surface by means of a special acrylic (EndLighten).

After doing ample investigations and having read reports on experiences from nuigroup… i thought.. alright.. this is worth a try.. and here we go… hum… now lets try it hehe

The project aims to switch the illumination technique of our small DI table (known as Xenakis – music creating tangible interface [1]) from rear DI to DSI. Here are some pictures of the table:
