Freetrack, a free webcam head tracking program with 6 degrees of freedom, has been upgraded to support all TrackIR games (including IL2)!

Site has demo videos.

Cool for us non-TIR users.

Anyone else got good diagrams to make that 4 LED and battery pack system?

Cool... I like freeware alternatives like this.

I don't have a cam however http://forums.ubi.com/images/smilies/35.gif

This would be useful to add the other 3 degrees of freedom that you can't get from a mouse (i.e. rotation, and translation up/down or side to side)

I can see that it would need 4 lEDs to get 6DOF but does it have a 'reduced functionality' mode for people using less LEDs?

I'll try to post something useful here, for the french-impaired.

His webcam has an IR filter on it.

The LED thingmajig has 4 IR LED's 4 resistors and a battery pack.

The system can also work with LEDs that emit visible light and doesnt necessarily need an IR filter.

Hope some of this helps.

No reduced functionality possible, single LED solutions that provide 2dof already exist, like Freelook and Cam2pan (links on Freetrack website). There is still an advantage using 4 LEDs over 1 LED when used in a game that only supports 2dof because the difference between head translation and head rotation can be distinguished. So moving your head to the side while directly facing the monitor won't be registered as a head rotation.
