FreeTrack is an open source software application that provides cost effective optical head tracking for applications & games. This software closely emulates its
...Plus commercial counterpart, TrackIR.
The headtracking is achieved by attaching infrared LEDs to a hat or clip in a special arrangement and then allowing the software to track these points through almost any webcam. This position data will then be provided to a game in real time such as ARMA II or DCS: World, allowing the user to freely look around their envionment.
This point model serves as a precise platform for mounting the infrared LEDs to a hat. The relative positions of these LEDs must be entered in the software, and less precise or changing measurements means lower performance for the user.
