Uhhh... not at all.
The photo says he’s looking at the screen, his eyes are pointing down. The other photo says he’s looking at the screen in iOS 13 beta 3, but his eyes are going straight.
Like it’s kinda obvious what they are trying to demonstrate. smh
FaceTime Attention Correction corrects what you’re looking at, so it doesn’t look like you’re looking at the screen.
An off-center camera will always do that, it doesn’t matter if the subject has changed angles or perspective, the user will always be looking away unless they look at the camera.
If you got the memo what FaceTime Attention Correction does, then you should easily make out what they’re trying to convey in the comparison. It’s not that hard.
1000% less obvious or well demonstrated than the side by side photo here though... https://9to5mac.com/2019/07/03/facetime-eye-contact-correction-in-ios-13-uses-arkit/
