	'''Field of view''' ('''FOV''') is the extent of the observable world at any given moment. Field of view is usually measured in degrees. Humans have 180 degrees FOV when looking directly in front and 270 degrees with eye rotation. The higher an [[HMD]]'s FOV is, the further the virtual world will extend to your edge of vision. You generally want an HMD with at least 90 degrees FOV.		'''Field of view''' ('''FOV''') is the extent of the observable world at any given moment. Field of view is usually measured in degrees.

	Changing cFOV can lead to unnatural movement of the virtual environment in response to head movements. For example moving your head for 7 degrees in real time creates 11 degrees of movement in VR. This can lead to discomfort and a maladaptive condition called vestibular-ocular reflex gain adaptation.<ref name="oculus_best_practices">https://developer.oculus.com/documentation/intro-vr/latest/concepts/bp_app_simulator_sickness/</ref>		Changing cFOV can lead to unnatural movement of the virtual environment in response to head movements.

	Display FOV or dFOV is the FOV of your [[HMD]].		Display FOV (dFOV) is the FOV of your [[HMD]].

	~~While wide~~ dFOV can increase [[immersion]] and induce [[presence]], it can cause [[simulator sickness]] ~~in certain individuals~~. Large dFOV can cause discomfort due to 2 reasons. First, humans are more sensible to the flickers and movements of images in the peripheries of their visual systems. Second, large dFOV means provides more overall visual input when compared to small dFOV. Too much visual input can cause conflicts with vestibular and proprioceptive system.<ref name="oculus_best_practices">https://developer.oculus.com/documentation/intro-vr/latest/concepts/bp_app_simulator_sickness/</ref>		Wide dFOV can increase [[immersion]] and induce [[presence]], but can cause [[simulator sickness]] for some people.
