Changes

'''Motion-to-photon latency''' also known as the '''End-to-end latency''' is the delay between the movement of the user's head and the change of the [[VR]] device's display reflecting the user's movement. As soon as the user's head moves, the VR scenery should match the movement. The more delay (latency) between these 2 actions, the more unrealistic the VR world seems. To make the VR world realistic, VR systems want low latency of <20ms and even really low latency of <20ms7ms.
