Sony Promises Better Face Identification Through Depth-Sensing Lasers
An anonymous reader quotes a report from The Verge: Speaking with Bloomberg last week, Sony's sensor division boss Satoshi Yoshihara said Sony plans to ramp up production of chips to power front and rear 3D cameras in late summer, responding to demand from multiple smartphone manufacturers. Though Yoshihara is geeked about the potential for augmented reality applications, the most intriguing aspect of this new tech would appear to be a better form of face identification than we currently have. The Face ID approach that Apple first brought into use on the iPhone X -- and others like Xiaomi, Huawei, and Vivo have since emulated -- works by projecting out a grid of invisible dots and detecting the user's face by the deformations of that grid in 3D space. Sony's 3D sensor, on the hand, is said to deploy laser pulses, which, much like a bat's echolocation, creates a depth map of its surroundings by measuring how long a pulse takes to bounce back. Sony's sensor chief argues this produces more detailed models of users' faces, plus it apparently works from as far away as five meters (16 feet).Read more of this story at Slashdot.
