*Evonik makes some different types of Endlighten. These vary in their thickness and also in the amount of particles inside the material. Available thickness ranges between 6-10mm, follwing “L”, “XL” and “XXL” for particle amount. I have tested the 6mm “L” and 10mm “XL” type. The 6 mm is to flexible for a table setup, the 10 mm works nicely.

Community Core Vision, CCV for short (aka tbeta), is a open source/cross-platform solution for computer vision and machine sensing. It takes an video input stream and outputs tracking data (e.g. coordinates and blob size) and events (e.g. finger down, moved and released) that are used in building multi-touch applications. CCV can interface with various web cameras and video devices as well as connect to various TUIO/OSC/XML enabled applications and supports many multi-touch lighting techniques including: FTIR, DI, DSI, and LLP with expansion planned for the future vision applications (custom modules/filters).

DSI requires a special type of acrylic known as Endlighten, which has microscopic mirror-like particles embedded throughout it. Using exactly the same LED configuration as FTIR, the infrared light fills the Endlighten acrylic. Because of the particles, the infrared light is reflected out of the acrylic, acting like a giant infrared emitter. Then, like a Rear Diffused setup, an object stops the infrared light, reflecting the light back to the camera and creating a blob.
