20,000 nits brightness “blind” your titanium alloy eyes

In the Metaverse, if technology can’t keep up, everything else is useless. No, Xiao Zha came with 4 headset models.

When Xiao Zha took out 4 VR model machines in one go, we knew that he was really playing.

If it was a gimmick to engage in the Metaverse before, then when Xiao Zha took out these “hard currency”…

We just have to worship.

Visual Turing Test: Four Challenges, One by One

It’s been almost a year since Meta changed its name, but the vision of everyone gathering in the Metaverse is still on the horizon.

A large part of the reason is that the display at the heart of VR headsets is simply too primitive.

In the past decade, this little thing has barely progressed: two low-resolution screens connected behind a lens trying to trick the eye into seeing a 3D world.

Clearly, we need a newer type of display, one that can match human vision.

However, before exploring the next generation of VR headsets, we need to understand a new word – “visual Turing test”.

Although the name looks very fresh, it is actually not much different from the Turing test proposed by Alan Turing in 1950, but it is changed to the field of vision.

That is to say, it is used to evaluate whether the picture displayed in the VR device is “true at a glance” (whether it can be distinguished from the real-world content).

Specifically, VR devices must meet the following four characteristics to pass the test:

1. Achieving a resolution comparable to retinal vision

2. Able to focus on virtual objects naturally

Specifically, the user can freely switch the focus of an object at any distance in the screen, and at the same time generate a corresponding depth of field effect.

3. Can compensate for optical distortion caused by lenses

4. Support HDR, that is, cover a wider range of colors and support higher contrast

Butterscotch: The clarity of the human eye, everyone’s vision 1.0

First up is Butterscotch’s model.

This head-mounted display is a cow, and its image quality is near-retina-quality. High-end headsets of this quality are typically only made by companies like Varjo that specialize in VR gear.

One more mention of Varjo, a Finnish company founded in 2016 by former Nokia and Microsoft executives. The biggest feature of this company is high definition – comparable to the human eye.

But Varjo does, Meta doesn’t right now. It can even be said that Meta is still far from the “line”, very far.

To achieve this design is equivalent to halving the 110-degree field of view of the Meta Quest 2. But it will also magnify the Quest 2’s 1832 x 1920 pixels per eye by a factor of 2.5, increasing the wearer’s vision to 1.0.

Zha said that Butterscotch provides about 55 pixels per field-of-view degree. That’s a bit lower than the retina standard of 60 pixels, and a bit lower than the Varjo’s 64 pixels.

Half Dome: Alias ​​”Flexible Zoomer”

The Half Dome, which came out next, is another long-running prototype.

The highlight of this headset is the ability to move the focal plane based on the user’s implementation. The optics used for zooming started out as a bulky mechanical system in 2017, before switching to a family of liquid crystal lenses.

And according to Meta’s internal research, the technology could create a more realistic illusion of depth in a virtual world.

In the Half Dome series, Meta first explores a zoom design that uses a mechanically moving display to change the distance between the display and the lens, thereby changing the depth of focus of the image.

Later, the team turned to solid-state electronics to make the zoom optics more compact and reliable.

Starburst: Light up the night, 20000nit big killer

Starburst is a much more difficult VR headset to implement, even more so than the aforementioned Butterscotch.However, the harder it is to land, the stronger the performance.

The headset has a slightly bulky design, so much so that it needs a handle to support its weight. At the same time, it is equipped with a powerful lamp, which can provide HDR lighting of about 20000nit brightness.

The brightness of the screen is measured in nits. Modern HDR TVs can reach thousands of nits, but the Quest 2 only hits 100 nits.

Xiao Zha said that it is difficult to say that this product is practical, and our first-generation product must not be able to make this. We use it as a laboratory bed that can be used for later research and study.

Our purpose in doing this is to find the right path. Take a look at what technology paths can really help us make meaningful progress in virtual reality.

Holocake 2: VR “thin and light” headset

The Holocake2, on the other hand, is working in a completely different direction.

Compared to Starburst, the purpose of Holocake is to make the VR headset lighter and thinner.

After all, it’s called “cake”, it’s too thick and crooked.

The headset is the next generation of a holographic optical technology-based device designed in 2020. Holographic optics bend light so that a thick, refractive lens can be replaced by a flat plate.

The final product may be about as thick as ordinary sunglasses. However, Meta is still researching how to develop an independent light source to power the lens. It’s almost certain to use a laser, not a regular OLED.

Zha said, “We will do a lot of engineering to achieve a practical laser that meets our specifications. Of course, we have to ensure safety, low cost, high efficiency, and the size is just right to fit into a VR headset.”

But to be honest, lasers are really hard to do now.

In order to be light enough at this stage, the Meta uses a Pancake lens, which significantly shortens the distance between the monitor and the lens (middle image below).

After all, compared to the holographic lens that has not yet been written, the Cambria VR headset with Pancake structure is almost on the market.

Comparison of three lenses

The Holocake 2 is a full-featured PC VR headset that rivals the Meta Quest 2 in terms of field of view, resolution, and eye-frame, in a thinner form factor.

The difference is that the Holocake 2 requires a wired connection and also doesn’t have an integrated computing unit and cooling unit.

That’s probably a cheap price.

Mirror Lake: Meta’s Ultimate Killer

After all, these prototypes just now are for a single test.

The ultimate goal of Meta is to integrate various visual elements required to pass the Visual Turing test into a lightweight, ultra-thin and low-power VR headset.

The big killer of the Metaverse is here, and Xiao Zha offers 4 VR headsets to challenge the visual Turing test

To this end, the team designed a prototype called “Mirror Lake”, based on the architecture of the “Holocake 2” mentioned earlier, and achieved this “ski goggle-like shape” through a holographic lens.

At the same time, it will incorporate all the advanced vision technologies Meta has developed over the past 7 years, such as eye tracking, variable focus, and more. In addition, “Mirror Lake” additionally supports lens attachments.

“Mirror Lake” is also said to offer new penetration technology and an external display that can show the user’s eyes and face to the outside world.

The key to the design of “Mirror Lake” is that the holographic projection technology makes each component thin and flat.Not only is the zoom technology pretty flat, but so is all the holographic film, distortion correction, and eye-tracking technology used in “Holocake.” This means the final product can hold more functionality while having a smaller body than any existing headset.

“Mirror Lake shows what a complete next-generation display system could look like,” said Michael Abrash, chief scientist at Meta’s Reality Labs division.

Knock on the blackboard!

Chief scientist Michael emphasized that “Mirror Lake” is still only a concept machine, and Meta has not yet produced a fully functional head-mounted device to prove that this architecture is indeed feasible. If such a head-mounted device can be successfully produced in the future, it will bring a revolutionary change to the VR visual experience.

Of all the VR prototypes, Mirror Lake is still the furthest away from commercialization, so if other display technologies prove more promising, it may be dropped in favor of other display technologies.

The whole point is real?

Remember the “mosaic” device that Xiao Zha tried on himself some time ago?

In the video, Xiao Zha “spit out the fragrance” and “wased the little hand”. It was really like blowing a fairy spirit and casting magic. With a bang, a phantom elf jumped into our eyes.

And Xiao Zha also smirked all the time.

Recently, Lynch posted on his Patreon page eight CAD files that appear to be schematics for Project Cambria.

Some interesting features are revealed, including a dial on the front (probably for adjusting the lens), a clip on the side (probably for Oculus Link), and a visible cable on the back that might connect the battery to a component on the front.

However, unfortunately, this “shy beauty” Project Cambria still has no product name, specific release window or exact price.

But Zuckerberg has said that Project Cambria will launch “later this year.”

Although we still have to wait for the “beauty” to appear, at least compared to those distant prototypes, this VR headset is expected to be available soon (regardless of the price).
