I didn't work these holidays, but I've made a picture of the principle of my project :
(full size here)
I thought that it was easy to make a touchscreen using 2 webcams but is seems to be hard to compute. So I'll use 1 webcam but the box will be deeper (+5 cm). This is a big box but the computer will be inside (considering the 1 webcam system, 40*29*27 cm). Normally, it will be smaller in the end (let's hope so...).
Concerning the "flat illumination", it's the system used by nima on the NUI group's forum. I have tested 2 rails of leds and it works pretty well. Of course it is possible to hide an area with your hands or fingers but I didn't succeed in doing this. The problem is the blobs are pretty big, due to some filters which are necessary to have an even ligthing.
The first test of the frame should be next week.
