Head Tracking with Cliffs of Dover

[Wolf_Rider]

TrackIR interfaceFreeTrack is compatible with the unencrypted version of NaturalPoint's TrackIR head tracking interface that has widespread support in simulation games. NaturalPoint have been using an encrypted version of the interface in more popular titles since late 2008, these can be identified as requiring TrackIR software version 4.1.036 or higher and are incompatible with FreeTrack.[18][19] First used in DCS: Black Shark,[20] it caused developer Eagle Dynamics to release their own head tracking interface but soon after cancelled it at NaturalPoint's request.[21] FreeTrack compatibility is still possible using [TrackIRFixer] to remove the encryption requirement, however this involves file modification which can conflict with some forms of DRM and online anti-cheat. Currently DiRT 2 and F1 2010 are affected by DRM, refusing to run after the fix has been applied.

TIRViews.dll is a dynamic-link library file distributed with TrackIR software that provides tailored support for a small number of mostly older games, using special interfaces or memory hacks to facilitate view control.[22] Though a violation of the TrackIR software's EULA,[23] it is possible to use the file with FreeTrack.

NaturalPoint's TrackIR interface SDK is only available under a signed license agreement[24] and is covered by a NDA, so while FreeTrack is open source, the TrackIR interface component is required to be closed source.[25]
