A month ago I posted a geek alert about multitouch surfaces. In one of the comments I said, "With a little tweaking you can combine ir sensor technology and a projector to create this kind of interactive surface on any wall. With a little more work you can make those interactive surfaces follow you from room to room and rotate to any wall in whatever room you are in. You could even "send" you screen around the room by passing it from one person to another."
I have seen the various kinds of technology that would be required to make this happen but today I have seen them combined. Below is the video on this. I"m not saying my comment gave someone the idea, but it is really cool that I mention it about the time they are filming this. Anyways, this kind of technology is right around the corner and the ways that these things can and will be used are very exciting. Like I said above, imagine using it to pass notes around when brain storming. You could write on a piece of paper then pull that paper off the pad and make a pass gesture and everyone in the room will get your completed idea. School use will also be incredibly useful allowing for each student to have displays that can be wirelessly moved up to the board or turned in. Fill out a scan-tron and when you are done the computer automatically computes your score before you leave the class.
Anyone else geeking out just a bit?
