By the looks of this, the need for interactive white boards will soon be a thing of the past. You should soon be able to control your computer using a webcam, a piece of free software, and well just about anything!!
Looks pretty amazing. If it can work on these complex games, I don't see why it shouldn't work on ordinary software and a data projector. Could save on buying those expensive IWBs. I've signed up for beta testing, so I'll let you know how it goes.
The company that produces this is called CamSpace and the product itself is called CamTrax.
