Google Can Tell if Someone Is Looking at Your Phone Over Your Shoulder (qz.com)

Dave Gershgorn, writing for Quartz: At the Neural Information Processing Systems conference in Long Beach, California, next week, Google researchers Hee Jung Ryu and Florian Schroff will present a project they're calling an electronic screen protector, where a Google Pixel phone uses its front-facing camera and eye-detecting artificial intelligence to detect whether more than one person is looking at the screen. An unlisted, but public video by Ryu shows the software interrupting a Google messaging app to display a camera view, with the peeking perpetrator identified and given a Snapchat-esque vomit rainbow. Ryu and Schroff claim the system works with different lighting conditions and poses, and can recognize a person's gaze in 2 milliseconds. Ostensibly, this AI software is able to work so quickly because it's being run on the phone, rather than sent for processing on the company's powerful cloud servers.
