Day Two OC4: John Carmack, CTO talks Mobile VR and GO specs

    Live stream: John Carmack, The state of Mobile VR

    "Cat videos are not surprisingly popular in VR"

    -John Carmack


    Day Two of Oculus Connect featured John Carmack, Oculus’ Chief Technology Officer, spoke primarily about mobile VR technology and their newly announced product,the Oculus Go. He talked about some of the issues encountered with development from an engineers perspective.  The two hour long event did not show demos, but gave insight on what it was like from his point of view.


    A few highlights of the keynote speech, as well as information on the Oculus Go

    • LCD screen is optimized for VR,although LCD is known for higher latency,newer screens can achieve 4-5ms. OLED is still a lot faster and was considered, but cost wasn’t implemented because of cost.Their may be black screen bleed issues on the screen
    • Spacial audio was added, knowing that most people use their phones for audio.Audio is important in adding an immersive environment. So, it was important to have a good audio board in place.
    • O-GO is running full-blown ANDROID
    • O-GO will not have bloatware that you would get from phones.
    • Spoke lightly about “VR Shell”, Which allows alot of content to be viewed in VR ( it's currently in beta for devs in Google Chrome)


Questions and Awnsers (not verbatim, Summarized)


Do you think Gear VR and GO Will converge?

J: Yes

Decided not to front facing camera in Go?

J:  Price.  I wouldn't have bumped the price up for it.

Do you see eye tracking as a requirement for full video rendering?

J: No

What is your wishlist for hardware in VR?

J: Rebuilding in ARM x64, generally mundane things like weight (cutting the form factor by half).  Ergonomics can be radically improved, we can reconfigure the componets.  But ones of the cools things about Go is its not very complicated.  I'd also have a couple good cameras for position tracking and AR, but it costs money and uses CPU power and thermal energy.  Ultra Wide angle lens, but so many things are trade offs. 
Social eye and face tracking,  but I'm not super excited about.  We'll all get this eventually.

Whats your stance on 180 and 360 videos?

J: What bothers me the most in 360 videos is bad stitching.  Almost nobody does a good job at it.  It's a lot of work! With 180 video, it's almost at the point where we can just press a button and you're good. 

What are you guys doing to keeping up to date with android in the standalone product?

J:  There's not a lot of proprietary stuff in the Android Kernel, it's mainly device stuff that we change.


Whats the battery like?

J:  I'm comfortable with decisions we made with Go,  there isn't any dramatic changes to the battery. 


Will Oculus try to lock out controllers seeing that they have their own that connects to the Go?


J: I wouldn't worry about it
