Article is really thin on details, I'm skeptical. Last I checked, pixel density was still a big issue with HMD's and text. Contrast, as well is a problem with AR style HMD's.
I'd love it if the tech really was there though, it would be awesome. I actually think using some flavor of DLP tech and a foveated display with eye tracking might allow for phenomenal pixel density, wonder if anyone is working on that yet.
- mappu 11y agoSMI are working on fundamental technology for foveated displays with eye tracking. There's also an HMD from FOVE on Kickstarter that intends to ship to backers in "Fall 2016". John Carmack suggested on Twitter that foveated rendering won't be a performance win until a few more generations, when higher-resolution panels are more commonplace. Right now the necessary tracking and layering could actually reduce performance compared to rendering the full scene.
- knughit 11y agoThere are applications where high resolution is interesting but high frequency is not.

- wlesieutre 11y agoAdditionally, every time you move your eyes, the high-detail area has to shift with them. If you did foveated rendering without low latency and high refresh rate, you're going to get visible pop-in of render detail levels. Haven't tried it, but I'd hazard a guess that it would be really uncomfortable.
- dshankar 11y agoThere is no such thing as a `foveated display` There is foveated rendering: a rendering optimization technique where you render at higher resolutions where the eye is looking at due to higher visual acuity in a small ~5-degree circle thanks to a large concentration of cones in the fovea of the eye. This has nothing to do with the actual pixel density of HMDs. Physical pixel density remains an issue, and foveated rendering does not solve that. edit: Perhaps I misunderstood, are you talking about retinal laser projected displays and concentrating the beam on the fovea?
