The Importance of "Field of View"

What is Field of View (FOV)?

By definition, the Field of View is the extent of the observable world that is seen at any given moment. Put simply, it is the line of sight from your eyes. The viewable area in front of your face.

FOV is always measured in degrees and is the arc of visible space in front of you. In relation to Sim racing or any game for that matter, the screen or monitor should act as a continuation of this line of sight without any unrealistic bending or shaping of view. Field of view can be measured in two planes, the verticle and the horizontal plane. As humans, we have a wider FOV in the horizontal plane, which is the reason why TV screens are rectangular. In AC and ACC, FOV is measured in Vertical Degrees and not Horizontal degrees like other platforms.

The best way to understand FOV is to imagine the screen as a window. Imagine yourself sitting in your car with your monitor on the dashboard. If the monitor were to act as a window, everything you see past that window is your effective field of view. If you move your body closer to that window, you can see more out of it, if you move further away from the window, you see less out of it. Essentially, FOV is there to replicate the view you would have if you were sat in the car in real life.

Why is FOV so important?

FOV plays a key role in your body’s sense of speed and distance. Your natural field of view helps the body determine where it is in relation to its surroundings. In terms of Sim racing, the correct FOV will help you hit apexes and raise awareness of your cornering speeds.
