Field of View
Formal
Field of View (FoV) represents the visual area in which users can see virtual content in an augmented reality headset. This term can also be explained as a measurement of the angle formed by the distance from the user to a fixed point in space and the bounds of vision.
Practical
FOV allows for coverage of an area rather than a single focused point. In virtual reality (VR), a large FOV is essential to getting an immersive, life-like experience. Wider FOV also provides better sensor coverage or accessibility for many other optical devices.
