field of view (FOV)

Field of view describes, in degrees, the range of what can be seen of a world at a certain point in time. In cameras the field of view is determined by the lens, with wide angle lens providing a larger field of view and a more telephoto lens providing a narrower field of view. In VR head mounted displays, field of view typically ranges from 90° to 110°.  For more immersive VR, it is important to have as wide a field of view as possible. The Lytro Immerge camera has a 120° field of view and is rotated three times to capture a full 360° scene. The Light Field is played back through either a Rift or Vive headset which have a 110° field of view.
