Some people take great pride in their EQ, i.e. their ability to recognise emotions and discern between different feelings, both in themselves and others. It is a powerful quality to have, and one that embodies to the very essence of being human. But is it possible that a device can detect human emotion better than humans themselves? Possibly, at least for some of us. New wearable tech developed by researchers at MIT can tell you how someone is feeling from the sound of their voice.
