Sorry Fred, I disagree, In a cockpit you move your head as in the reality, some time just small moves from your shoulders, depending on your emotions, your gesture (like tunning the radio), or with more ample moves of you neck when you try to see if a traffic isn't hidden behind the cockpit frame or before engaging a step turn in a thermal. You are *not* looking from a fixed position. Even with tightened harness. What should be unrealistic is panning down the view when you lower the head down to the keyboard or mouse. What is really needed is looking down on the side as when you try to catch a mark or look under to see the ground trafic when you are vertical of an airfield (ok, airliner pilots don't do that). I know that head tracking wont improve the perception of the outside scenery as would do a 'per eye' system and in that matter you are right Fred. Then Joe is perfectly right with 3D cockpit experience, they would be really impressive with such a 3D effect. But again, the move tracking should be limited to translations. Let me explain my (translating) point of view : For a single screen display, with option for secondary displays not showing the FG world : Rotations should be done only with a manual input so the focus stay on your flight track even when you are looking for a pencil on your desk or when you turn the head to your secondary screen displaying Atlas. Then the move to show what is behind the cockpit frame or to improve your view on the lower sides could be done with a combination of rotation manual input and translation tracked input. In our case, (flight simulator) head rotation tracking isn't a good thing as when you turn your head you don't look any more at your screen. And pan the focus with small head rotation moves (to show the sides of the cockpit or scan the sky) will transform the experience in a nightmare. The ideal behaviour of such a system will certainly not follow exactly the real movement of our head and should be designed to improve our capacity to scan the sky as would do a glider pilot or take marks as an acrobatics pilot, but *only* on demand. By the way, improving the immersion feeling in the cockpit with 3D view is just a 'plus' for now, it will certainly be a 'must' in the next years.
