Find: They'll be watching -- MIT's computer algorithms can tell why you're smiling better than a human can

Not sure I want to be watched. 

MIT's computer algorithms can tell why you're smiling better than a human can

MIT smile research


While some recent studies have found that investment in facial recognition technologies hasn't yet yielded great success, researchers at the Massachusetts Institute of Technology continue to move the ball forward with a system that can outperform humans at recognizing the emotion behind a person's smile. The group's study involved the difference between a happy smile and one generated out of frustration. To begin, the researchers asked subjects to act out two different emotional reactions: joy and frustration, both tracked by webcam video. MIT's algorithms analyzed the footage to determine the character of the reactions as did a group of regular humans; both could determine the express emotion with similar accuracy. The researchers then...
