Learning the world of body language elicits the same reaction: "At last, I'll learn how to be a human lie detector!" Facial expression is a huge part of how we communicate with other people. However, most of us only have an intuitive knowledge of non-verbal communication at best. It was reported that Chinese scientists created an online polygraph that uses facial recognition to study minute changes in facial expression, skin colour, temperature and heart rate - all of which could reveal a lie. The machine is also fitted with artificial intelligence to analyse visual and voice data to look for changes that indicate someone is not being truthful.
