What software did you use? TouchLib?

where can i get the software or is it like homemade?

The software isn't rocket science. You segment the image into three parts: Background, shadow and touch point. The blue dye makes the touch points more easily visible. Excluding QuickTime boilerplate to get the camera running, it was about 80 lines of C. It posted mouse events for single touch and broadcast multitouch data through 'notifyd'. Since there's immediate feedback, there's no need to calibrate the screen position.

ok, well the actual amazing part is the software, not any thing else, its been done before, but not DIY and with infra red cameras, already calibrated to special positions, i doubt this is real, or you are some sort of genius.

What software is that?

Are you retarded? Can't believe anything is doable if a TV Zombie can't do it? The way it works is so dead obvious i can't believe anyone could have difficulties understanding how it works. Camera points from below to bag - Where bag is pushed - water is pushed aside - camera only has to track where the image isn't blue. Thats it. There are ready made libraries for stuff like that for many programming languages.

It's actually more like a Tactiva pad, since you can see where your fingers are on the screen. It's too bad those never made it to market -- it seemed like a good compromise: You get to see the whole screen (even while gesturing), *and* you get to keep your hands in an ergonomic position. The main problem I had was camera latency. The Tactiva pad seems to have had a *real* touchpad, so I assume it would respond instantly (only the ghost image would lag).

it's more like a multi - touch pad than a touch screen. It's next to my computer, it's not the screen that I'm touching. But it is a neat idea.

it's not fake it uses a camera under the glass table to track his fingerschange that into input
