Also how close you are to the screen plays a role, again being closer means the screen is occupying more of the natural field of view.īut this is largely irrelevant. A bigger screen will occupy more of the human field of view.

So the size of the screen you are displaying on matters. This is however unsuitable for games on a normal screen, as the screen doesn't occupy your complete field of view (if you were displaying on VR glasses or IMAX cinema or something like that, it would be a different case). Actually humans have a field of view of almost 180 degrees, with clear vision in about 120 degrees, at least according to wikipedia
