A quick explainer on the promise—and risks—of TrueDepth in the iPhone XS
Apple's new iPhones launch this week, and unlike last year, every one of the new devices comes equipped with the TrueDepth sensor array originally found in the iPhone X. Most consumers who are interested in Apple's products know that piece of technology drives Face ID (an authentication method by which you log into your phone just by showing it your face) and Animojis, those 3D animated characters in Messages that follow your facial expressions.
But Apple and the developers who make apps for its platforms have more applications for the 3D sensing tech planned in the future, and consumers might not be aware of them. In this video, Ars Technica's Valentina Palladino and iOS app developer Nathan Gitter talk about how TrueDepth works, what exciting things it might be used for in the future, and what users have to look out for in terms of privacy and security concerns.
