VR: Minimal Latency

You probably know a serious problem with VR is latency, the delay between moving your head and your eyes seeing the visual response. It is considered the primary cause of Simulator Sickness, aka motion sickness, AKA sea sickness, etc. A part of that delay comes from how long it takes the display screen to refresh the image it displays.

I suspect many of us haven’t realized that for Augmented Reality the problem is even worse. In AR we are seeing the world in real time with perfect sight and head movement synchronization and  an lagging AR image super imposed. While there is less chance of simulator/motion sickness the lag is visually obvious and annoying. See the video.

NVIDIA is experimenting with 16,000Hz (16KHz) screens. My Samsung screen provides a 120Hz refresh rate, more than 1,000 times slower.

We can get acceptable AR for most uses with way lower refresh rates. However, NVIDEA’s tech will provide crisp images even in combat games and athletic efforts where head motion is extreme.
