This wearable will tell you how other people are feeling from the tone of their voice

Researchers at the Massachusetts Institute of Technology have developed wearable tech that could help avoid crossed wires and miscommunication. Using artificial intelligence to detect the "tone" of a conversation based on speech patterns, the researchers were able to use a wearable band to "classify the overall emotional nature of the subject's historic narration". More simply, the band could spot signs of sadness, anger, boredom and so on from a person's voice. The project, by Tuka AlHanai and Mohammad Mahdi Ghassemi at CSAIL, is one of many aimed at'social coaching' designed to help people with chronic social disorders become more comfortable with the complexities of communication. Day-to-day life is underpinned by social interactions that play a key role in our mental health and development.
