FaceTrackNoIR and FreeTrack: FOSS head-tracking (like TrackIR) - use any webcam to link to freelook /movement in games
FaceTrackNoIR ( download ) enables a user to use any webcam,by moving their head very slightly, to control the free-look/xyz movement of any game, through joystick emulation via PPjoy for Windows or directly when the game developer has included support. Very popular with space/flight simulation community, this technology can be used with FPSs/3rd person RPGs as well. FaceTrackNoir uses the protocol developed for FreeTrack, among others , including FlightGear's own. Webcams known to work well with FaceTrackNoIR. Normally this type of control through head movement was very expensive, and required specialised IR cameras/lights/markers to acquire raw data which was processed through closed source software and sent to games via protocols like TrackIR, being aimed at the high end simulation users. The FreeTrack opensource project used cheap but specialised equipment, wrote their own processing software and sent the data to games via reverse engineered TrackIR protocol/FreeTrack pr...
