Managing VR motion sickness
VR motion sickness, or simulator sickness, is a real symptom and a concern for virtual reality. Researchers, psychologists, and technologists with a wide array of specializations and PhDs are studying the problem to better understand the underlying causes and find solutions.
A cause of VR motion sickness is a lag in screen updates, or latency, when you're moving your head. Your brain expects the world around you to change exactly in sync. Any perceptible delay can make you feel uncomfortable, to say the least.
Latency can be reduced by faster rendering of each frame, keeping the recommended frames per second. Device manufacturers such as Oculus and others see this as their problem to solve, in both hardware and device-driver software. GPU and chip manufacturers see it as a processor performance and throughput problem. We will undoubtedly see leaps and bounds in improvements over the coming years.
At the same time, as VR developers, we need to be aware of latency...
