iOS 13’s third developer beta includes a new feature that makes it look like you’re staring directly at your front-facing camera during FaceTime calls, even when looking away at the person on your screen. The Verge reports: Normally, video calls tend to make it look like both participants are peering off to one side or the other, since they’re 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.
On Twitter, Dave Schukin explains that the effect is being achieved using ARKit, which is used to map a user’s face and adjust the positioning of their eyes accordingly. Using the arm from a pair of glasses, Schukin shows how the software is warping the eye area slightly to achieve the effect. The same effect also appears to be present when wearing sunglasses.
