IR is great but has a lot of size restrictions. capacitive is very thin, but requires an intensive manufacturing process, far far out of our league. I was thinking that if we used the same principal of an LLP (laser light pane)="Diagram"]http://www.codelaboratories.com/images/LLP/LowPressure.jpg except instead of using cameras we used a material that reacts to the presence of IR laser light (such as IR detection cards). the easiest way would probably be conductivity so as the conductive state of the material changed we could pin point an X and Y coordinate and map in the same way as the camera would map it (to maximize hardware/software compatibility across different platforms) Not sure if such a material exists, might be one for the invention books :D Just getting around to ordering some new IR LED's and line generators, should get a working build done before new years :punk	The Error Guy (14052)
