Has anyone messed with the various head tracking teks ?
Plumbed for a trackhat http://www.trackhat.org/ It uses a branch of the opentrack software. https://github.com/opentrack/opentrack Cheaper alternative to the trackir's.
I managed to compile it and run it fine, couple of bugs though, The main dev dont seem to like Linux unfortunately(Go read the issues forum on the git page). I have posted about it on the trackhat forums too.
I have it working via the lib-udev plugin, down side is that a lot of the protocols are windows only. eg the freetrack plugin that is used in games like Euro truck simulator 2.
I have got it to work with the virtual joystick (lib-udev) plugin fine.
I have tried linux-track, works but very limited as its aimed at custom built apps.
Any one else fiddled ?
