Head trackers don't map movement 1:1, more like 1:10 (or so). Thus if you want to look 180 back, you turn maybe 30degs but can still eye the screen. Basically you gesture with your neck.
It sounds awkward but it works very well as an input method. It's also way less intense than VR for longer sessions.
Not saying it's absolutely superior, just that it's pretty good as designed.
