The moment where I can put everything together is reached. For now I use 2 trestles that must support my acrylic. The frames with LEDs are mounted on the sides (provisionally with adhesive tape) and the camera is underneath the plate. With Touchlib I play with the options (mainly through the use of filters), making a clear as possible picture of my touches on the plate.

In this first test I notice that direct sunlight or other ambient light of the sun is a bad factor because it’s the largest source of infrared light. From now on there will only be tested in a dark room with minimal ambient light. The camera gives a clear picture of the touches (after the outbreak of the IR filter in front of the lens!).
