Software engineer Dave Schukin pointed out on Twitter that the feature uses Apple’s ARKit “to grab a depth map/position of your face, and adjusts the eyes accordingly,” sharing a video of how it works.

The feature is reportedly only available on iPhone XS and iPhone XS Max if you have the beta operating system installed on your phone, and it’s unclear whether this is a feature Apple plans to roll out more broadly down the line. We have reached out to Apple for comment and will update with a response.

Video chatting is certainly more intimate than other text-based forms of communication, but the design oftentimes has you looking into the screen rather than the camera—that’s how you can see the person on the other end. This feature effectively allows you to continue to do that while also making it appear to the person you’re talking to that you’re looking them in the eye. If it works as intended and doesn’t lead to some wonky eye contact, it’s a pretty useful feature for those who want to appear peak invested without having to stare into that tiny little camera lens.
