> I have no issue looking around in any of the games I use trackIR with So you have screens behind you? And above you? And to either side of you? And at other odd angles? Suddenly your $200 is looking a lot more expensive, otherwise you're comparing apples to plastic oranges. Screen coverage for _actual_ free look would cost many times more than an HMD, take up many times more space, and it will _still_ be feeding the same image to both eyes unless you use 3D goggles which is yet another expense (a very significant one if you don't want your framerate to crater because you've just cut your display Hz in half). > It gives you the exact same freedom of input This is blatantly false. Freedom offered by motion tracking is restricted to screen space. A VR HMD integrates a full sphere of stereoptic screen space, something that you're deliberately ignoring.
