VR teaching projects under the Internet

So far, most attention has been focused on the prospects of consumer augmented reality glasses, which some expect to materialize in the next few years. Abrash predicts that AR glasses technology will not reach the "BlackBerry era" of mobile phones until 2030.

This is due to the difficulty of incorporating new display technology and tracking systems and processes into lightweight glasses, and to some extent have battery life that lasts throughout the day. This new display technology will need to display artificial images that are nearly opaque while also allowing most of the real light to pass through.

But Abrash believes the "most difficult part" is developing the appropriate input system. Carrying a controller is impractical and awkward for complex inputs, and people are unlikely to want to use voice commands or wave in public.

"In the long run, what users really want is to make the interface work the way their brain perceives it. Rather than requiring the user to say,'I want to hear this person speak,' imagine that when the user is in a noisy environment, the glasses will detect the noisy sound, infer who the user is talking to, and then select that signal. Users don't even need to know what's happening. Glasses can sense user needs to provide better display and interaction effects."

Eventually, when these technical obstacles are resolved, Abrash expects AR glasses to replace smartphones. But according to Abrash, this won't happen until 2030 or even 2040.

Abrash acknowledges that other companies share the same understanding of the potential of AR glasses: "Everyone thinks AR will one day replace mobile phones."

AR can replace phones, VR can replace personal computers

When asked about competition in the VR space, Abrash expressed his belief that Facebook has invested more money than any other company, and he believed that the real "way out" for the next generation of VR must be through his team's research:

"No company is close to our current level. When the next generation of VR comes along, it must be because we did it. There will be absolutely no other possibility."

"I was actually impressed by Facebook CEO Mark Zuckerberg and Facebook's strong commitment and belief in VR. Everyone sees that AR will someday replace mobile phones, but I think VR is as important as AR, AR can replace phones, and VR can replace personal computers."

Over the past few years, Facebook has revealed in-depth research into the technology needed to push virtual reality into the true next generation. Including research on zoom optical displays, compact wide-angle lenses, eye tracking, facial expression tracking, realistic avatars, tactile gloves, AI-based concave rendering, room grid division and reconstruction, wireless video transmission, etc.
