FreeTrack Forum

Hi,
being wii remote support in the works (I just bough one because of this), how many LEDs are needed for the tracking setup?
Will the accelerometers be used so maybe two LEDs are enough?
Or is the typical 3 LED setup used?
Thank you for this great project! Is there any place where I can download the sources in development (CVS, sourceforge...)?

As far as i know, the first (if not only) priority is to use the wiimote only for head tracking, so accelerometer would be useless - unless you want to wear the wiimote on your head :P
Since the wiimote will only be used as a camera, you'll probably be able to use it with any currently supported FT setups (1, 3, 4 LEDs).
The point of using it isn't to have a wii-like control on your PC, but to have fast head tracking - the wiimote does all image processing required to locate each point on the captured image and calculate its coordinates (the process that right now takes most CPU time used by freetrack) all by itself , and then sends coordinates of up to 4 points it sees to the FT. From now on, getting actual head position its a matter of simple calculations (easy for a computer to calculate, not easy to program ). That's how the TrackIR works by the way - all image processing is done by hardware.

If you want to use the wiimote as you would on a wii, search for software called GlovePIE - it supports its accelerometers, and probably the sensor bar as well, and is extremely configurable - it's a kind of scripting language, you could actually write a freetrack-like head tracking in it using the wiimote.

New version of GlobalPie supports TRACKIR with Pro-Clip and the Wii..

Really want to know if FT will support the Wii with 2 point IR ???

The wiimote is used as a camera so offers the same tracking options as a webcam.
