With so much multi-image computational photography and video processing these days, I've been wondering whether we could have a multiple camera system (with cameras on the top, bottom, left, and right of the screen) and a processor that can simulate a camera in the center of the screen - or even dynamically moved to the eyes of the caller. I know there's a bunch of research on viewpoint interpolation, but how close m…

Tracking speakers is best done via audio already linked to camera control. Now face tracking by camera's in VC was something I first encountered late 90's - can't recall kit, but Sony was first on that - which was good for presentations in which the person speaking was standing and moving.

As for perspective shifting based upon multiple inputs - processing wise look at raytracing as would need to map each camera input to extrapolate the suface details and then map that out to the virtual visulisation. Basicly you would need to 3D map, including textures and re-render that viewpoint required.

However, do you need the whole face - you just really need to fix the eye's IMHO and eyeline contact.

But that is down to how we interact in meetings with people - try doing a video conference in which everybody is wearing dark sunglasses - that is insightful as you find people focus more upon what they hear more then.

This trick has been used for a whole in VC studio's for decades and I first encountered this in the 90's. Being able to get eye-level contact with the camera when people will want to look at the screen - this just solves that. Just not cheap. Though lighting was always key and with the two-way mirror set-up, you will want a few more lumens to compensate for loss of that mirror in front of the camera.

Quite cool although:

1.) I find if you put the video conference window top and center of a monitor--preferably a larger one--it works pretty well so long as you make at effort to keep your eyes towards the top of the screen. This is especially important (and takes some discipline) if you're presenting from slides.

2.) The general recommendation, which is my experience as well, is that the webcam should be up at eye level or maybe a bit above. So if you are using a laptop, it should be up on some books or other type of stand.

The GlideGear iPad teleprompter is under $200 and saves a lot of time if you’re pressed for time:

https://smile.amazon.com/gp/product/B019AJOLEM/

The setup is to use an iPad hosting Sidecar wireless display from your Mac. Use Moom or similar screen management app that detects kicking on the new display, and pops your meeting video windows onto it at full dimensions (but not ‘full screen’ mode).

If the other person is both on video and sometimes sharing content, you need to flip the video horizontally, which isn’t obvious. There are three options:

1. Check if your display can flip the video.

2. Use SwitchResX if your graphics card can do it for that particular monitor:

If it can, great. If it cannot, then ...

3. Use the Flip Mac Window utility from here, so you’ll see it the right way around in the mirror:

https://www.freetelepromptersoftware.com/mac/

How this works is it screen captures the original window, and plays it back flipped over top of the window. That means actual buttons / icons are not moved, only the rendering of the window is flipped. If you need to navigate the window, unflip it first.

Note that 12.9” iPads only fit in this GlideGear if you re-shape the mirror brace, but the mirror is large enough for a 12.9” iPad and it looks fantastic.

I like coupling this with Logitech Brio (best) or Logitech Streamcam (good).

I‘ve used it extensively with WebEx, Zoom, and Teams.

Well, I really hate eye contact and never look people in the eyes, so this wouldn't be something interesting for me. I wonder if I am alone or if this is common.

I'm curious if you look at yourself in the eyes when you're facing a mirror?

No, I usually don't.

It's funny how videos such as this, which are optimized for engagement over learning, explain things in a backwards fashion. Instead of explaining how the thing works, and then showing you how to make the parts to build one yourself. They show you how to make the parts, and only explain what it is you're building at the very end.

He never said the video was supposed to be about learning. The entire channel seems to be based around technology crafts. It's not my cup of tea but that doesn't mean no one else shouldn't enjoy it.

Oh, I didn't say no one would find it enjoyable. It's quite the opposite, actually: videos optimized for engagement tend to be more enjoyable for most people. You don't get to 2.4 million subscribers by making videos that no one likes to watch, after all.

At the end of the video, he tried it with his friend who's not using the apparatus. Yet, her eyes seem to be looking at him too. What do you think?

Me too. I felt like she was looking more into my eyes than he was. Maybe I've just gotten too used to video calls...

He also wears brightly colored contacts and opens his eyelids extra wide to create an uncanny-valley fake-human youtube persona.

His lightbox setup is better than his mom's, but everything else about his setup was worse.

it's common for people suffering from autism spectrum disorders, not so much in the general population.

We're not suffering from autism spectrum disorders; we're suffering from people starting at us.

Couldn't you lie the screen completely flat and build it the other way (reflecting the screen and passing through the camera), avoiding the keyboard problem?

That's how traditional teleprompters work: screen below reflecting off the half-silvered mirror, camera behind. Many laptop screens don't open completely flat, so that may not work for this particular concept.

Flat (really, parallel to ground) doesn't matter -- you just need to adjust the angle of mirror to match.
