==Display FOV==
Display FOV or (dFOV ) is the FOV of your [[HMD]].
While wide Wide dFOV can increase [[immersion]] and induce [[presence]], it but can cause [[simulator sickness]] in certain individualsfor some people. 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>
