This is my first attempt at implementing a cheap IR laser into the ORION V2.
Essentially the laser creates a horizontal beam of InfraRed light approx 1mm off the glass, which is broken when fingers make contact with the surface of the glass.
This results in the IR camera seeing a bright 'Blob' where the finger has touched the glass.
A great solution to the limitation of using the Multi-touch screens during the day or under a lot of ambient lighting. A big thankyou to AlexP for the Laser idea!
