hey how do they use this for where u touch ion the actual screen??, but it still uses touchlib to sense blobs i dont get how they do it

[Lorsk8]

Normally they do it with a projector under an glass/other transparant material screen. Then they also have some IR-LED's shining on the screen from the side or the bottom (rear illumination or diffused illumination). Then a IR sensitive camera/webcam will notice that the IR-beam is shining back because of your fingers, that will make the blobs on touchlib.

If you still don't get it, PM me :)

dude you calibrated that thing real good, how is it doing so well with such little light?

[Lorsk8]

There surely was enough light, but you can't see it on the vid. I didn't calibrated it at all, I just did configapp till I got bright white blobs and I ran the smoke app. I was surprised of the fact it did so well... If you have any more questions, please just ask it.
