Glasses That Can See Your Emotions

Expression-recognition software company Affectiva, set up by electrical engineer Rosalind Picard and Rana el Kaliouby from the University of Cambridge, develops technology that helps improve the understanding of emotion. They have created prototype glasses with a tiny in-built camera linked to computer software that identifies different emotional facial states: thinking, agreeing, concentrating, interested, confused, disagreeing. The camera tracks “feature points” on the person you are facing, letting you know what they are feeling via an earphone and a light on the glasses, with more detailed information available on the computer running the software.

These glasses could prove to have many uses, for those people suffering from autism who find it difficult to read social cues and facial expressions, to companies wanting to measure how people feel about their products, adverts, movies, etc.
