AMAZON SAYS IT CAN DETECT FEAR ON YOUR FACE. YOU SCARED?

Rekognition has been assessing emotions in faces along a sliding scale for seven categories: “happy,” “sad,” “angry,” “surprised,” “disgusted,” “calm,” and “confused.” Fear, added Monday, is the eighth. However the online documentation for the service warns that it “is not a determination of the person’s internal emotional state and should not be used in such a way.” And as Amazon, Google, and Microsoft charge ahead with algorithms that intuit feelings, psychologists warn that trying to read emotions from facial expressions is fundamentally misguided.
