5 VR Glass Problems and Meta Innovations to Solve Them

If you’ve ever used a VR headset like Quest or PlayStation VR, you’ve probably been overwhelmed. But at no time did you doubt that what you saw was “real” or just “virtual”.

Will we ever really be able to confuse the two? In Meta, this challenge is known as the “Visual Turning Test”. Alan Turing, the father of computing, predicted that, in the future, a computer would be fully capable of mimicking humans – Meta just explained his term and now says pass for virtual reality. Will go

And the company has made steady progress toward that goal. Meta CEO Mark Zuckerberg met with the press last Thursday (16) to present prototypes and studies created by reality labs dedicated to VR and metaverse productions.

Below is a summary of how they want to overcome the most common flaws in virtual reality mirror technology so that our own eyes are exactly the same as the way we see ordinary reality.

1- Change of focus

In real life, our eyes and brains adjust quickly when we choose to focus on a point in our vision. Right now, you’re looking at your computer or cell phone, being able to recognize each of these little letters. But if you decide to look ahead, your vision will quickly adjust to focusing on windows, people on the street, or other objects in the environment.

VR glasses still can’t do this transition easily. But since 2017, Meta has been working on a series of prototypes called Huff Dome, the latest iteration of which, Huff Dome 3, introduces an invention called Verifocal.

In short, it is a technology that tracks the eyes to understand where you want to focus, instantly adapting the image displayed on the display. Imagine in a zombie game: you can clearly see the shotgun in your “hands”, but also the indie that appears at the end of the corridor, which will grab your attention.

2- Distortion

The rotation of the VR lenses and the nature of the creation and projection of the virtual image on the lens still cause some rotation or expansion in the elements which are more on the margins of the field of vision.

Currently, headsets try to solve the problem with a stable solution, but it does not cover all the variables, depending on where the user is looking.

Meta has created another prototype with 3D TV technology and software that mimics a VR lens to be able to read them.

It’s like a quick test lab, where a team of reality labs can test different algorithms to correct changes, without necessarily wearing a headset.

3- Resolution

Some TV and cell phone models have already exceeded the target of 60 pixels per image angle, which allows for a “retina” resolution, similar to the human retina. Why aren’t VR glasses there yet?

Because the pixels are spread out to cover a large area to mimic the depth of the field. This reduces the final resolution.

The basic premise is text: it is difficult to read anything virtual with very “thin” letters. Looks like you’re on one of these tests at the ophthalmologist’s office.

The Realty Labs team has managed to overcome a hurdle in a prototype called Butterscotch (“Caramel”), with a new type of hybrid lens that has brought Quest 2 (the headset model currently sold by Goal) to the field of view. Reduced to about 50%. .

According to Zuckerberg, the machine practically solves the problem of resolution – now the problem is to fit all this technology into a lightweight, ergonomic device, so that it can operate commercially.

4- Shine

Also, according to Matrix of Reality Labs, nature is 10 to 100 times brighter than the best high-definition television images currently on the market. And, according to Quality Research, this lack of liveliness is the biggest obstacle to the notion that a virtual image is as perfect as real.

This is where the Starburst test product comes in – the first VR headset with HDR (High Dynamic Frequency). This feature, already present in some TVs and monitors, creates sharp, bright images with impressive realism.

In HDR, the light output is measured in units “nits”. Quest 2 can emit up to 100 nuts. Some TV models come close to 10,000 nits, which is considered a parameter that best represents the general reality. Start Burst manages to reach 20,000.

The problem is that the equipment is still an impractical, heavy-duty device that researchers hold close to their faces by straps, as if it were a pair of binoculars.

5- Weight and size

Let’s face it: no image created in VR will make a user “stupid” unless a huge headset is squeezing his head and constantly reminding him that he is in the machine. Is “stuck”.

Meta is moving to make it smaller: Prototype Holocaust (“Holobolo”, in free translation) is the smallest and lightest VR headset they have ever made. It’s fully functional, able to run any existing VR program – just connect it to PC (still via cable).

To reach the dimensions of ordinary sunglasses, the engineers behind the Holocaust used two new techniques. The first, called polarization-based optical bending, reduces the space between the display panel and the lens.

The second is even more inventive: it uses flat holographic lenses instead of the traditional curved lens. This is a brand new proposal in the market, which has a lot of potential to become standard in the future.

It will be possible to combine the powers that be. Half domeOf butterscotch Is from Starbust In a lightweight, portable device? Another project in this direction is Aina Lake (“Lake Aina”). For now, it’s not even a prototype yet: it’s just a design, the shape of which resembles the glasses worn by snow skiers.

This will measure the progress of the meta over the last seven years to win the visual touring test. But it will take a few more years until it is finally mass-produced and marketed at affordable prices.
