In this video, the camera configuration of the game Skyrim is modified so that instead of the camera's viewpoint and its pivot point being the same, the camera's viewpoint is moved a few inches forward—like our eyes are relative to our necks. The result is striking, and responses are divided between awe and motion sickness. Are you a "this is beautifully realistic!" person or a "this makes me puke!" person?
Ever notice the view is wrong in all first person games that exist today? In reality when we look around our eyes don't just rotate but actually swing side to side and even up and down. As an example this video shows Skyrim configured for our real vision.
