Zuckerberg demonstrated four VR head display prototypes, and meta revealed the "family" of metauniverse

Source: heart of machine

adopt VR equipment ,Meta The exploration of the metauniverse has never stopped .

Today, ,Meta CEO Zuckerberg and AR/VR department Reality Labs Chief scientist Michael Abrash Present their latest... At the virtual Roundtable VR Head display prototype , There are four types of equipment , The codes are Butterscotch、Starburst、Holocake 2 and Half Dome.

The focus of this exhibition is Meta be called 「 Time machine 」（time machines） The design of the ： A huge proof of concept for testing a particular function , Such as super bright backlight and super sub screen .

According to the technology media Verge Reports of , Zuckerberg said ,「 I think we have taken a big step towards reality , In the future, it will not take too long to create scenes with basic perfect fidelity .」 Although display technology is not the only unsolved problem , but Meta Yes VR The in-depth study of hardware provides help for it .

Now we will introduce these four prototypes one by one .

Butterscotch It is an attempt to approach the quality of retina imaging , You can be in Varjo And other high-end head display devices of the company , But with Meta The current product line is different . however ,Butterscotch It is far from the delivery stage , It is generally necessary to Meta Quest 2 Of 110 Halve your view . It provides a resolution of approximately Quest 2 Of 1832x1920 Pixels per eye （pixels per eye） Of 2.5 times , Allow users to read on the vision test form 20/20 's line of sight .

Zuckerberg said ,Butterscotch Provides about 55 Pixels per field of view （per field-of-view degree）, This is slightly lower than Meta Of 66 Pixel per degree retina standard and Varjo Of 64 Pixels per degree .

Starburst The design is a little cumbersome , It uses a powerful lamp , It takes hands to support the weight , Can produce 2 Wannit brightness HDR lighting . Zuckerberg said , take Starburst It is very unrealistic to consider the development direction of the first generation products , But it can be used as a test platform for further research .

And bulky Starburst Different ,Holocake 2 To be thinner and lighter . It is 2020 Successor of head display equipment based on holographic optical design in , The device uses a light bending technology , A thick refractive lens can be replaced by an almost flat panel . The result is a head display as thin as sunglasses , but Meta Still working on the development of an independent light source for its power supply , It is almost certain that it is a laser rather than the one commonly used nowadays OLED.

According to Zuckerberg ,Meta A lot of engineering work needs to be done to achieve consumer grade lasers that meet their own specifications , It's safe 、 Low cost and efficiency , Suitable for thin VR Head display .

Half Dome It is Meta A long-running head display prototype series , The focal plane can be moved according to the user's line of sight . These zoom optics are in 2017 At the beginning of the year, it was a heavy mechanical system , Later, liquid crystal lens array was used . according to Meta Internal research , These liquid crystal lenses can be used in VR Create more compelling （ Physically comfortable ） The illusion of depth .

Half Dome Product line development .

As early as 2020 year ,Meta will Half Dome The technical description of is 「 Almost ready for prime time 」 了 . But in today's show , Zuckerberg appears more cautious .「 These things （ Distance practicality ） It's still far away ,」 He is answering about 「 Prime time 」 Comment on the question and say .「 We are trying to , We really hope to integrate it into one of the upcoming earphones , I believe we will do this sometime , But I won't announce anything in advance today .

Reality Labs Will be in 8 Of the month SIGGRAPH More research will be discussed at the conference , Including how to more accurately capture the real picture of mixed reality .
