Since it seems to be a similar device, but not real Trackir, OpenTrack/FreeTrack would have to be used – and these are quite configurable on their own. Y-axis is not really needed however, since internal sensors on the DK2 provide that quite well. It’s essentially only leaning towards/from the screen which isn’t captured at all (and of course drift correction, which, however, is impossible to solve with this method, as i now see it).
I do indeed like to tinker, and will try to report back regardless of how it goes, since it’s quite intriguing :))
