The brainchild of iAd team members, Apple boasts its invention will make it possible to 'charge a higher rate for mood based content delivery' by scrutinizing 'channel characteristics, demographic characteristics, behavioral characteristics, spatial-temporal characteristics, and mood-associated characteristics.' Apple further explains: 'Mood-associated physical characteristics can include heart rate; blood pressure; adrenaline level; perspiration rate; body temperature; vocal expression, e.g. voice level, voice pattern, voice stress, etc.; movement characteristics; facial expression; etc. Mood-associated behavioral characteristics can include sequence of content consumed, e.g. sequence of applications launched, rate at which the user changed applications, etc.; social networking activities, e.g. likes and/or comments on social media; user interface (UI) actions, e.g. rate of clicking, pressure applied to a touch screen, etc.; and/or emotional response to previously served targeted content. Mood-associated spatial-temporal characteristics can include location, date, day, time, and/or day part. The mood-associated characteristics can also include data regarding consumed content, such as music genre, application category, ESRB and/or MPAA rating, consumption time of day, consumption location, subject matter of the content, etc. In some cases, a user terminal can be equipped with hardware and/or software that facilitates the collection of mood-associated characteristic data. For example, a user terminal can include a sensor for detecting a user's heart rate or blood pressure. In another example, a user terminal can include a camera and software that performs facial recognition to detect a user's facial expressions.' Your move, Google!"
