iOS 13s third developer beta includes a new feature that makes it look like youre staring directly at your front-facing camera during FaceTime calls, even when looking away at the person on your screen. The feature, which was spotted by Mike Rundle on Twitter, only appears to be working on the iPhone XS and XS Max with this version of the beta, and can be toggled on and off from within FaceTimes settings.
Normally, video calls tend to make it look like both participants are peering off to one side or the other, since theyre looking at the person on their display, rather than directly into the front-facing camera. However, the new “FaceTime Attention Correction” feature appears to use some kind of image manipulation to correct this, and results in realistic-looking fake eye contact between the FaceTime users. Coincidentally, Rundle himself theorized back in 2017 that Apple would one day do this, although not so soon.
