Again in June Meta revealed its newest XR R&D efforts by a handful of various prototypes designed to show out numerous ideas. The subsequent step, the corporate says, is to carry all of it collectively right into a single bundle that would at some point attain actual customers.
Should you spend time maintaining with the most recent XR analysis (as we love to do), you’ll know the overwhelming majority of the work being performed is about proving that one thing is potential, however not essentially about whether or not or not it’s viable as tech that might be made into an actual product—the place challenges like price, manufacturing, and sturdiness can nix even essentially the most modern applied sciences.
Take, for example, the ‘Starburst’ HDR VR headset prototype that Meta just lately revealed. The purpose of the analysis was to easily construct one thing that labored so the group might quantify the impression of 20,000 nit HDR on immersion. However from a market-viability standpoint, the tech used within the prototype is way too massive, attracts an excessive amount of energy, and will get approach too sizzling to be constructed into an actual product with out fully altering the underlying structure.
And that’s the case for a lot of of Meta’s R&D prototypes—they’re designed to exhibit an idea, however they aren’t essentially designed to be market-viable.
However Meta’s subsequent prototype, the corporate mentioned alongside the reveal of its newest R&D in June, is an effort not simply to exhibit an idea, however to carry a lot of the corporate’s newest analysis collectively right into a single headset—and in an structure that would truly type the muse of future merchandise.
That doesn’t imply it could be low cost and it doesn’t imply it could straightforward, but when it comes collectively as the corporate hopes, it can “be a recreation changer for the VR visible expertise,” says Michael Abrash, Chief Scientist at Meta Actuality Labs.
The prototype idea known as Mirror Lake, and whereas Meta has been cautious to say that it hasn’t even been constructed but, the corporate says its purpose is to pack a lot of its newest improvements into this single system.
In keeping with Douglas Lanman, Director of Show Methods Analysis at Meta Actuality Labs, Mirror Lake will embrace digital varifocal lenses (together with prescription correction), multi-view eye-tracking, holographic pancake lenses, superior passthrough, reverse passthrough, and a laser backlight in a goggles-like form-factor. Let’s break these down briefly one-by-one.
Digital Varifocal Lenses
Digital varifocal lenses would permit the headset to indicate appropriate depth to every eye individually and in addition eliminates the necessity for eyeglasses. This might not solely make the headset extra immersive, but additionally extra comfy too, as it could repair the longstanding ‘vergence-accommodation battle’ that afflicts most headsets.
Multi-view Eye-tracking
Multi-view eye-tracking might enhance the accuracy of eye-tracking (which is a keystone for different options like dynamic distortion correction) by giving the system extra views of the person’s eye. Most eye-tracking headsets immediately have a digicam contained in the lens at a pointy angle that watches the person’s eye to estimate its motion. However that sharp angle makes it tougher to get an correct estimate. Meta says Mirror Lake might embrace an extra eye-tracking digicam in every strut of the headstrap close to the person’s temple. This digicam would get a greater view of the person’s eye by a mirrored image from a holographic movie embedded on the headset’s lenses.
Holographic Pancake Lenses
Holographic pancake lenses are novel lenses which can be thinner and lighter whereas permitting the person’s eye to be nearer to the lens, decreasing headset bulk significantly.
Superior Passthrough
Superior passthrough options will permit a sharper and extra life like view by the headset for blended actuality capabilities. Lanman didn’t go into a lot element a few so-called “neural passthrough digicam” proposed for Mirror Lake, however ostensibly this will likely be akin to a next-gen model of the Passthrough+ function on Quest 2 which goals for correct depth illustration and low latency.
Reverse Passthrough
Reverse passthrough is a considerably funky expertise that tasks the person’s eyes onto the skin of the headset for others to see. Since eyes are such an vital a part of communication, this function goals to make it much less bizarre to have a dialog with somebody who’s sporting a headset.
Laser Backlight
Laser backlighting would permit the headset to show a wider vary of colours to extra precisely signify what a person would see in actual life. It might additionally make for a brighter show with a wider dynamic vary.

Meta has demonstrated many of those applied sciences independently in numerous prototypes, however Lanman says the purpose is for Mirror Lake to be constructed round a “sensible structure;” that means one thing that’s viable exterior of a lab setting—one thing that would truly type the idea of an actual product.
Abrash, Chief Scientist at Meta Actuality Labs, mentioned Mirror Lake might glimpse what a “full next-gen show [VR] system might seem like,” but additionally warns that the structure gained’t be conclusively confirmed (or disproven) till the headset is definitely constructed.
It will likely be years but earlier than we see one thing like Mirror Lake truly attain the market. Meta’s upcoming headset, at present often known as Mission Cambria, will solely embrace a fraction of the capabilities of Mirror Lake. Even the Holocake 2 prototype—which is extra superior than Cambria—remains to be a number of steps behind what Meta is envisioning with Mirror Lake.
Nonetheless, Meta CEO Mark Zuckerberg insists that the billions the corporate is throwing at its XR R&D efforts isn’t merely educational.
“We’re the corporate that’s the most severe and dedicated to principally the place VR and AR should be 10 years from now. [We ask] ‘what are the issues that we have to clear up’ and simply systematically work on each single one in all them as a way to make progress,” says Zuckerberg. “There’s nonetheless an extended solution to go, however I’m excited to carry all of this tech to our merchandise within the coming years.”
