I only just found your site today and I was about to go out and buy a Wii Remote to start playing with when I had an thought: You mention that the Wii Remote consists of an IR Camera.... Would the same thing therefor be possible with an IR Web cam?

something like: http://www.ebest24.com/en/pc-100m-pixels-usb-6-ir-led-webcam-web-cam-cameramic.html?language=en&currency=GBP

I'm guessing the camera linked above would not work since it actually "see's" all colours and not only IR although it iluminates with IR, or am I wrong.

Sorry if this question has been dealt with before. I just thought I would fire the question off.

Thanks

David
Ps. Awsome work Mr Johny Lee.

Hi David,

Most web cameras will indeed capture the visible light and also the IR light. Therefore, you will need an additional IR band pass filter if you would like to work on the web cam.

The main issue with using the web camera will be the refresh rate and latency. Your computer will need to do a lot of processing to extract the IR points in real-time from the video output.

However for the Wii Remote, the built-in microprocessor handles the computation of the IR points and outputs them via Bluetooth. This has allowed the Wii Remote to work very well with the interactive whiteboard.

You can take a look at shakespeare1212's response: http://www.wiimoteproject.com/general-discussion/alternative-ir-pen-tracking-replace-the-wiimote-with-digital-camerawebcam/

Regards,
Boon Jin

That makes perfect sense. Thanks for that... definitely worth the few extra dosh. (Not that much more after all ;-)

I'll test it on a borrowed remote first anyway.
