I notice that at least in the Q400 the space in which you can move while using TrackIR is rather limited. A bit too limited to my liking. I have a hard time looking down out of the window or moving forward or sideways. Too often I bump my head to the invisible wall. The box is obviously smaller than the space you have in the cockpit: it's not that I bump my head against the window or anything: I can't even get that far!
Is there a reason for this limitation and is there a way to remove it? Or could this be changed in the future...?
