How I think what will work? 3D video chat? You need a diagram for two cameras, a 3D monitor, and ordinary 3D glasses?
Or did you mean something else? Perhaps something you've been assuming I'm talking about because your response to abstract notions is hostility and arrogance, rather than a search for common ground and understanding? Perhaps you've assumed all this time that I've been saying a specific product, the Rift, could be used for face-to-face interaction, because you didn't ask, but instead called me a six-year-old idiot?
And now you have changed the rules again. Don't pretend like you're looking for common ground when you keep changing the fundamentals of the discussion.
The discussion is, oculus rift, 3d chat. Diagram it.
That may be what you want the discussion to be, because then you "win" according to some "rules" you wish existed, but it's not. Or wasn't, rather. The discussion is long over. It was over the moment you decided to be a dick.
So no then. You can't. Because it doesn't make any sense and it's a bad idea. I'm sorry you had to be the person who had the idea and I'm sorry I had to be the person to call you on it.
Okay, to be honest, everybody has this idea about VR. In your mind you see a glorious 3d representation of person you are chatting with, if your imagination is powerful enough, you can even feel the frame of the headset on your face and the wash of the display glow against the contours of your nose. But everybody who ever thinks about this idea, and is in a position to try and do it, runs into the same fundamental problem. Because in their imagination and their dreams, they're never in the place of the person they're chatting with, to see what they're seeing and they never realize that what the other person must see is them with a headset on...and then they realize the person they first saw in their dreams must have one on as well and the entire illusion shatters. You can't achieve the kind of telepresence we all wish for today or anytime in the near future.
I know you're struggling with accepting this scenario, but I've watched this same scenario play out for 30 years. There's nothing new about the Rift except it's consumer cheap. I've personally used systems better than the Rift and the moment you get the headset on, you realize VR telepresence, via video, won't ever work.
Nobody wants to have that kind of chat experience, so the only other possible mode is to do it with avatars.
The experience is obviously not what you or I are talking about though, even the first link which actually uses a VR headset (the Rift). But there's a very long list of well known issues to surmount that haven't been solved yet for very good reasons. No amount of "let's suppose that..." will make some of those very hard things a reality. At least not with the goal of something the general public will accept in enough volume to make it worthwhile.
Sorry to be a dick, but there really are unworkable ideas. You're a consultant, you know that you sometimes have to break bad news to the people you work for when they simply can't do something because it's not possible. You might come across as an asshole when you do, and people's feelings might get hurt, but somebody has to break the bad news.
