Read the article. Which three uses of emotion-detection does it mention beyond advertising?
Advertisers know when you're heartbroken
An advertising group has apologised after leaked documents showed it offering clients the ability to reach users at "moments of emotional openness" — identified, among other signals, by late-night scrolling, sad-song playlists and recently deleted couple photos. One slide suggested ice cream and budget flights sell best "within 72 hours of a breakup."
The company insists no private messages were read. "We detect patterns, not secrets," said a spokesperson. Critics were unimpressed. "They built a heartbreak detector and sold it," said one privacy campaigner.
"If a stranger followed you around noting when you looked tearful, we would call the police."
Emotion-detection is spreading fast: cars that notice driver frustration, call centres that score customer anger in real time, and job-interview software that reads "confidence" from candidates' faces — a use now banned in several countries after studies showed the software reads some faces better than others.
A teenage user was unbothered, then suddenly not. "I don't care if it knows I'm sad," she said. "I care if it decides what to do about it."
