Yo everybody.

I recently discovered about the wiimote whiteboard project and I couldn't be more enthusiastic about it.

So, as a imaginative guy I think I am, I began thinking on nice ways to use it.

I jumped the projector use. Since I like to draw and such, it would not fit cause of the shadows. and they are so D*MN expensive...

So I thougth of the direct screen use. And so I thought that, with time, all that touching would end on damaging a LCD screen. So I tried to think on a way to protect the screen, so I could draw with no worries.

then, I managed to think of this.


A somehow utopic working table.

Would the IR pen still work through a thick sheet of glass (or equivalent thick transparent material) put some centimeters away from the screen?

Beforehand, sorry for any broken english.

You could get away with a massive scrren protector like they use on PDA's

Problem with seperation is the angle will change based on your head position, so if you calibrate sitting tall, then as using system slump in your chair the viewing angle and thus calibration will change.

Im just using an 0.5mm thick sheet of plexiglass/lexan which doesnt interrupt the light at all, and gives a nice surface for the IR to reflect off.

Just taped in place around the edge with clear tape.

My displays are currently on 2 axis monitor arms, but soon to be 3 axis gaslift arms.

a rear projected screen would be nice...

(this setup uses a different kind of software - but I think it will work just as well)
