Hi,
Actually , I'm doing a project on Wiimote interactive whiteborad, and I was thinking about using the infrared pen just as marker on whiteborad.
So, for example , I'll use 2 pens representing black and red markers.
My question is , how can the wiimote differentiate between the signals sent by the 2 IR pens and respond to them respectively. is that possible?
I know that the wiimote can detect up to 4 IR dots but how it will respond correspondingly.
Thanks and waiting for replies =)

For all intents and purposes, this isn't possible. An IR light is an IR light is an IR light.

Thanks for your reply,
another question yet, can we add buttons to the pen representing right and left clicks of the mouse?
thanks

I doubt that would be possible. The light is standard IR light, which is not visible, and it would almost be impossible to detect one pen from the other reliably.

I'm about to publish a proof of concept where the mouse location is indetified through the Wiimote and left click/right click/centre click is sent through a BT mouse.

I think it will be quite doable to integrate a BT mouse into an IR-pen

I would think that the challenge here would be making a system that was portable enough, pen sized as it were. There's a youtube video where, while they don't say this is what they did I'm pretty sure it is and the pen has a huge wire running off it. I assume the circuit board for the mouse is hidden somewhere off camera.

I understand on how it can't distinguish the difference in lights, BUT could the Wii Remote detect a difference in intensity? If it can, then I would say set up an IR field to project IR Light  to be reflected off a shinny surface on a set of gloves (or pen) and then when you push the tip on the board or close your thumb and pointer, another small IR LED (Higher brightness) would go off, indicating a click.  If this is possible, I have a set of gloves I could build for this for a step forward in the interface. Any thoughts?
