Changes

Latency is the delay between action and reaction. Having low latency is crucial when using a [[Head-mounted Display]] for [[VR]] or [[AR]]. As you move your head, your [[HMD]] should display the resulting changes immediately. Any significant delay will cause your brain to reject the legitimacy of the virtual world and cause you to lose [[presence]]. High latency can also cause [[simulator sickness]]. In AR, high latency can cause virtual content to be misaligned with real life features.
