This guy used a Wii Remote and two homemade infrared pens to create a multitouch whiteboard system.

The Wii Remote connects via Bluetooth, and the NiTs have Bluetooth... see what I'm getting at?

Can anyone think of any good ideas?

The Wii remote would probably save some processing but one of the first things I plan to check out when I get the N810 is the infrared response of the built-in camera. Any one with an 8x0 want to see if the camera can see a tv remote? If so then we might be able to something without the Wii remote plus maybe a IR LED or two.

yeah it would be real fun... BUT
what would it help? you will need video output, won`t ya?
we first have to try getting some video signal out there # so you ONLY have to search on the board after you`ve disassembled your IT, put some wires on it and connect them to a beamer

Maybe not, what about drawing in mid air? (I don't know how you'd calibrate it...) Maybe input to a game? I remember the old logitech webcams had a game where you had to pop baloons or knock a basketball into a net based on your movement on camera.

Wiimotes work very well with NITs - http://www.internettablettalk.com/fo...8&postcount=12

I "majored" in Computer Vision - using onboard cameras to detect human movement and gestures is pretty hardcore and processor intensive stuff at the best of times - especially when you take into account how noisy the onboard camera is. You could possibly squeeze something cohesive out of the NIT but it'd be pretty basic imo [i.e. "detect the presence of flesh tones in coarse quadrants in a stationary cam's FoV"] No good for intricate tracking.

It'd be better if you were holding something distinct, say - a vivid coloured ball; and calibrate that against say 2 distinct coloured points you know don't move.

Cool! I can see it as Nintendo RVL-CNT-01 on my 770. Someone wanna compile those libs?

Yes, I tested this on my N800 a few weeks ago, and it can see the infrared.

Hmmm. So far as I know, the commands sent from a remote are just a series of IR flashes. I doubt it would capture at a high enough frame rate to do things like let the TV remote control the volume or brightness of the tablet.
