Is this working on a similar system to Optical touchscreen technology? Did you build the ir sensors into the edge of the glass or at the surface?

Different technology. This is what we've used: http://www.touchscreen-me.com/technologies-comparison-infrar... Same result can be achieved with CMOS sensors mounted on the corners as well but ambient lighting conditions affect the way the board works.
