Inflatable Touch Screen System
What’s an Inflatable Touch Screen?
A portable and simple way to have a touch screen system. This inflatable touch screen allows you to quickly set up an interactive system. Because the tracking equipment and projector can be set up behind the screen you can interact with the front without disturbing the image. Set up takes ten minutes provide you have an L.E.D. touch pen and a wii-mote. I have not tested with ir laser projection yet.

ir light pen.
The simplest form of a switched ir light pen is a AAA battery, wire, and an ir. led.
1. Bend the wire into an L .
2 the bottom of the L goes on the negative battery terminal
2. + on led to + on battery
3. push L wire down on the (-) led terminal
4. tape and pray
The one in the video is more complicated and rechargeable.

That is a great idea... makes sorting your screen a snap. And rear projected goodness makes it easier to tack the Ir from the pen. Will be sharing this idea...
