It called 6D movement since the camera tracks both your head position as well as your head direction (tilt) , thus it's 3d X 2 = 6D. Still head tracking works the best if your are very close to the camera. With Johnny Lee's famous wii head tracking video noticed Johnny does a good job keeping the video camera dead center on the screen for the depth to work correctly. The problem is of course unlike a camera just because I got my eyes dead center on the TV screen doesn't mean I got my head pointing dead center toward the screen. This became very obvious to me when the first time I started playing with TrackIR. I realize just how much my head moves (even though my eyes stay centered on the monitor) while I'm playing games as I had to learn to keep my head still and pointing in a certain direction. |
I still don't think it presents much of a problem, I don't think many people are turning their heads much at all while playing, it could perhaps present a problem if you simply change position to be comfortable... but watching that video again the screen isn't perfectly in the middle all the time, and well within bounds if you kept your eyes looking forward (like I said if you play games with your head diagonally it might look odd)
The human mind can sort these things out quick enough for you not to even notice unless you are trying, for instance when you have the remote on your lap it is difficult to tell that the pointing is not 1:1 with the TV screen, and the mind adjusts so that you can easily move your hand and stop it at any position on screen even if you are not directly pointing at it.
The only problem I could see is sometimes you might stop playing for a second and look away from the screen, but if it was blinkered like I said earlier that could be eliminated.
And I am guessing it's just called 6D to make it sound better like the six-axis, because tilt, roll and pitch are not classed as extra dimensions.
