Some time ago I had talked about Johnny Chung Lee and his project to create a 3D television thanks to wiimote. Despite seemed that the possibility of alternative use of wiimote were exhausted, the ingenious Johnny has proposed a stunning new project can bring fiction and reality, allowing a touchscreen-style Minority Report.

Thanks to the wii remote, in fact, you can turn the screen of a PC or the drape of a projector in real blackboards sensitive to touch, making us able to control the computer or write and draw a freehand.

The idea behind this hack exploits the mechanism contrary to that normally used by wii: wiimote receiver becomes fact, ready to pick up the IR radiation emitted by a pen led.  Thanks to the ability to receiving the wiimote addition, you can use up to 4 pens, resulting in a multitouch screen.

Projects and software needed can be found on the official website of Johnny, along with a video that goes back below.
