free optical motion tracking application for Windows

FreeTrack is a free optical motion tracking application for Microsoft Windows, released under the GNU General Public License. Its main function is inexpensive head tracking in computer games and simulations but can also be used for general computer accessibility, in particular hands-free computing. Tracking is sensitive enough that only small head movements are required so that the user's eyes never leave the screen.

Head motions are tracked with six degrees of freedom (6DOF), specifically; yaw, pitch, roll, left/right, up/down and forward/back. This is done by means of a video capture device, typically a webcam, which is placed in front of the user and tracks a rigid point model headpiece. This point model usually consists of infrared LEDs but can also be normal LEDs and even retroreflective material illuminated by a source of infrared light.

FreeTrack can output head tracking data directly using TrackIR, SimConnect and FSUIPC interfaces, programs that support these interfaces are regarded as having FreeTrack support. General input devices can also be emulated, specifically mouse, keyboard, and joystick (via PPJoy).
