“[Apple’s] patent application, No. 13/556023, describes system that would determine a sort of baseline mood for a given user by collecting and analyzing a mixture of physical, behavioral, and contextual data. The system would then compare this baseline to the data it collects from a user as the ad is about to be served to figure out what mood the user is in and subsequently, which ad the system should send to him or her.”
That’s sure to improve my user experience.
