One of the more striking products at InfoComm 2010 was the interactive PointDraw MP780 ST projector, which lets users take a "pen" and draw anywhere on the projected image.

But even more, the systems allows projection on almost any surface, and no calibration between pen and projector is needed. That happens automatically, because the projector puts invisible markers or the screen (or whatever surface you choose). The pen has optical sensors and figures out where it is in relation to the surface, and sends all the data to the projector on the 2.4 GHz frequency.

The pen can "write" in different colors of light with some clicks.

The projector itself also packs a variety of inputs, including a mic jack and Ethernet for up to four external computers.

And, the whole thing comes in at around $1,599.

Schools in Plano, Texas, used the projectors in a recent pilot program. Here's a video that makes it clearer.
