Or you can just look at the camera instead of the screen

This is surprisingly difficult with a device like an iPad or smartphone in landscape where the camera is off to one side. Even knowing where the camera is, the image of the person on your screen that you're talking to tends to pull your gaze back. You can do it; it's just an effort.

And if both parties are doing it you might as well just cut the video.

Yes, but you've now created a non-transparent OLED display, which already exists.

Oh, you mean a transparent LCD display, I see now.

Technically LCDs are all transparent, if we're not counting the backlight.

I'm excited for transparent OLED's simply so that laptops and monitors will be able to put the webcam behind the display, ~1/3 from the top. Then videoconferencing software can automatically move the image of the person you're talking to so their eyes are roughly centered on that point. And finally everyone gets to make direct eye contact again!

Visionox is already doing this in an upcoming cell phone design:

Yeah, I was thining a full-color, backlit LCD system, basically a computer monitor.

I think that’s a poor approach. While you end up with gaze more in the center of the display, you don’t always have a face directly centered. This alleviates some of the problem, but doesn’t remove it. A better approach that I’ve always wanted is to have four cameras on the corners of the display that generate a real time photogrametric projection of your face. This would mean not only would your camera view be dead…

It would be relatively trivial to automatically keep the face of the person you're talking to centered around the webcam using face detection. As a person moves in frame, your computer will "pan" to keep them centered.

Four cameras is intriguing, but also expensive and complicated, and will probably have a very rough time with things like eyelashes, edges of hair, different patterns of reflections on the eyeballs, different glare from lighting, etc. Realistic photogrammetry is really hard in practice, and runs the risk of being really uncanny valley.

Assuming the transparency (article says 70-80%) can be improved for clarity and the pixels small enough then it could be great. However you'd have to keep in mind that others looking at your face could see the same image. So don't go running that "X-RAY:make them appear naked!" app...

Sunglasses block much more than 30% though. And can have a mirrored surface so others can't see your eyes, or your creepy app notifications :)

Fair point re: sunglasses! Not sure "mirrored" would stop light being projected back through but may well help disguise it. Maybe a simple black LCD layer to block the outgoing light might help.

Also, I don't want the creepy Xray app.

But porn has this way of working into society/technology so I don't doubt for a second some form of that app will exist if it doesn't already.

DIY Perks did an interesting mod for this: https://www.youtube.com/watch?v=2AecAXinars Basically a box and a two way mirror.

Nobody's forcing you to make eye contact. :) You can still be totally free to not look directly at the person while talking to them. I mean, in normal conversation it's not like you're making constant eye contact anyways. If you did, you'd come across as a total psychopath. It's just so that when you want to make eye contact, you have that choice!

now i figured why i creep people out

I’m curious why software can’t correct this now? Messenger can make me look like a sheep, can’t it move my gaze?

It can, I've tried gaze correction software, but it has the unfortunate side effect of making the speaker look possessed. Total uncanny valley. We humans are sensitive to every tiny detail of the eye, because we express so much emotion through it. It's no joke that the "eye is the window to the soul". Gaze correction software literally winds up looking like it messes with your soul. Maybe someday we'll invent gaze co…

I recall once having a conversation with someone working on computer vision at Facebook, and they mentioned that the company had spent a considerable amount of talent & resources trying to get this feature to work cleanly and they did not get past the uncanny valley problems.
