I never used TrakcIR and probably never get used (I tried facetrack and dislike it)
I use NewView (you control freely your views with hat), for me a better solution that not hurt my neck
Is also possible configure 6DOF positions...
Try using it! You can download from our forum (in Portuguese - google is your firend):
