Pay-per-gaze? Google patent proposes ad system
(Phys.org) —Advertising models could in the future expand from clicks to pupil dilations. Google's patent for a Gaze Tracking System became public last week. Originally filed in May 2011, the patent presents an idea for wearers of a head mounted device—and in 2013 observers are guessing this may be Google Glass—to have gaze tracked so that the system can pin down exactly what the user is looking at and even the emotional responses via pupil dilation. Information about where the user was gazing when viewing the external scene would be sent over to a server. Then the real work would start. An image recognition algorithm would be executed on the scene images to identify items within the external scenes viewed by the user. A gazing log tracking the identified items viewed by the user would be generated.
