The projector itself doesn't detect touch, it's the "board" that detects touch. It's like a touch screen surface (think like a Nintendo DS) but without the ability to generate an image. Instead, the projector projects one onto the surface. I believe the PC software that manages this has a "sync" option to line things up correctly (press the dots, that sort of thing).
If there's a percentage of schools that don't yet have these, they will, or something like it, very soon. College is no comparison, because colleges are privately owned, so they are going to be run differently.
At any rate, ALL teachers now have PCs in their room at the very least. You'd be hard pressed to find a single exception, except of course on TV, which was the original reason I posted this, to say that TV writers (and movie writers for that matter) aren't doing their research on how schools have changed.

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
