During the Oculus Connect opening keynote address, Michael Abrash shared his predictions for the next 5 years of VR development.
The most important and obvious advancement will be video. PC-based headsets like the Rift and Vive have roughly a 100 degree field of view and 1080p display panels, which equate to around 15 pixels per degree. Humans are capable of seeing at least 220 degrees field of view at around 120 pixels per degree (assuming 20/20 vision), Abrash says, which gives us an idea of how much improvement VR still has to look forward to. In layman’s terms, this is around 24K – per eye. Currently, 4K panels are just starting to be readily available at stores, and those panels are at least 40″ big.
Quoting roadtovr.com: “In five years, he predicts a doubling of the current pixels per degree to 30, with a widening of FoV to 140 degrees, using a resolution of around 4000×4000 per eye. In addition, the current fixed depth of focus of current headsets should become variable. Widening the FOV beyond 100 degrees and achieving variable focus both require new advancements in displays and optics, but Abrash believes this will be solved within five years.”
For this to happen, Abrash says that “foveated rendering – a technique where only the tiny portion of the image that lands on the fovea—the part of the retina that can see significant detail—is rendered at full quality, with the rest blending to a much lower fidelity. This saves a lot of processing power, making it possible to render dual 4k pixels at 90hz.”
The report also covered topics like advancements in eye tracking, audio, improvements in wireless throughput, “augmented” VR, and the “dream workspace”, as well as general ergonomic, hardware, and user experience improvements. For complete details, check out roadtovr’s report here.
