No, you had it right the first time. The software does so-called "motion scaling" so you only have to turn your head a little bit when sweeping your in-game camera around. See this video for a demo of the concept.Diablohead said:Watch the video posted above again if you have not, when he is inside the car the camera just moves about with him in a realistic way, they could make it so if you turn your head 10 degrees it turns 30 degrees in-game, no idea how well the camera can detect faces. They could also make it so you don't even turn your head but move it left and right to make it rotate in the game.
If you mapped head motion to camera rotation it would be confusing, non-intuitive, and you would lose all the benefits of being able to move the camera when you move your head.
