In virtual reality, the concept of ‘presence’ is described as the perception of being physically present in a simulated, nonphysical world in a way that fully immerses the user. A key obstacle to achieving presence is addressing motion-to-photon latency, the time between when a user moves their head and when his or her eye sees an updated image reflecting that new position. Minimizing motion-to-photon latency is critical to achieving both presence and comfort, two key elements of great VR.
