Multi-Touch Update: Found the problem
I figured out what was wrong with my Multi-Touch Box. Due to the large dimensions of it, I only had about half the illumination I needed. That rather bothers me, because I don’t really want to spend another two days just soldering LEDs. So I found a better solution;)
There is another Multi-Touch Method that I have not talked about before. It is called LLP(Laser Light Plane). Basically, you put one infrared laser in each corner of the screen, pointing straign up. You then put a line lens above each laser. Line lenses take a dot and scatter it into a solid line. This is then projected over the entire suface. The goal is to get this plane as close to the actual surface as possible(on the top). Then, when you touch it the light is scattered downward, and picked up by a camera.
I ordered four Infrared 10mW 780nm Lasers and four 120 Degree Line Lenses from Aixiz.com, for a total of $38. I should be receiving them by Friday. Ill post my success(or failure) then, with some videos if it worked.
