FaceTrackNoIR is a free open source application for head tracking which supports different methodes of tracking, e.g. faceAPI (face tracking) and AIC Inertial Head Tracker.

The tracker "PointTracker" works like NaturalPoint's Track IR with TrackClip PRO. How it works (simply explained):
Three infrared LEDs on a clip (http://www.trackir.fr/13-68-thickbox/...) are tracked by a camera and the positions processed by the software.


The components for a 3-point (LED) headset-clip and a used PLAYSTATION Eye webcam cost 25€ or less. Building the hardware is quite easy and can be done even without knowledge of electronics. For comparison: Track IR 5 + TrackClip PRO is sold for 188+€ (241US$) in my region (official destributor).

• What's basically needed:
webcam (get a used PLAYSTATION Eye with CL Eye drivers... It's pretty much the best choice)
light filter for the webcam (e.g. exposed and developed photographic film or a floppy disk's magnetic layer)
3 IR LEDs
power source (e.g. batteries, USB*)
cables
resistors
PTC fuse (if you're planning to use power from your motherboard via USB)
