Apple has fixed eye contact in FaceTime calls using image manipulation.
For the longest time, FaceTime chatting has always felt a little impersonal. This is because users tend to look at their iPhone or iPad’s screen and not the camera while on the video call. The effect is that you’ll see the other person looking downward on your chin or mouth and not straight in the eyes.

Guys – "FaceTime Attention Correction" in iOS 13 beta 3 is wild.

Apple has enabled an option in their beta version of iOS 13 called FaceTime Auto Correction. Through image manipulation, the effect is such that it looks like the users are looking at each other on the screen and not the camera.
How iOS 13 FaceTime Attention Correction works: it simply uses ARKit to grab a depth map/position of your face, and adjusts the eyes accordingly.

This feature is only available on the iPhone XS Max and the iPhone XS as of the moment. It can be toggled within FaceTime settings and could be a while before it shows up on public beta. Right now it’s unsure if it’s only for devices that have TrueDepth camera technology or if it’s available on all iOS devices.
