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 [[Motion Sicknesssimulator sickness]]. In AR, high latency can cause virtual content to be misaligned with real life features.
Minimizing latency is one of VR and AR's biggest challenges. Human brains can detect very small latency in the visual and audio systems. These systems have to bring latency low enough to be undetectable by the brain.
