IR Pens / Focusing an IR beam?
« on: February 15, 2008, 05:51:16 PM »
Is it possible to focus the beam of IR light like a laser pointer, so that a user could stand back from the whiteboard and hit links on a web page, sort of like an air mouse?

Specifically, I need a source that can project IR light to a half-centimeter spot at a distance of 5 feet.

Is this possible?  Would the beam disrupt the Wiimote's tracking? I suspect it would, but if I'm wrong I'd love to hear about it  :D
