Eye-tracking system uses ordinary cellphone camera From: MIT News - 07/15/2016 Crowd-sourced data yields system that determines where mobile-device users are looking. Researchers developed a simple application for devices that use Apple’s iOS operating system. The application flashes a small dot somewhere on the device’s screen, attracting the user’s attention, then briefly replaces it with either an “R” or an “L,” instructing the user to swipe either the right or left side of the screen. Correctly executing the swipe ensures that the user has actually shifted his or her gaze to the intended location. During this process, the device camera continuously captures images of the user’s face. In addition to making existing applications of eye-tracking technology more accessible, the system could enable new computer interfaces or help detect signs of incipient neurological disease or mental illness.
