Google glass could read your emotions - and send them to advertisers

A new app for Google Glass claims to be able to tell you exactly how someone is feeling. Called Emotient, is can tell whether a person is happy, sad angry or confused - and can monitor an entire room of people at once. The firm says the technology could even be used by advertisers to gauge reactions to their products. The Emotient software processes facial expressions and provides an aggregate emotional read-out, measuring overall sentiment (positive, negative or neutral); primary emotions (joy, surprise, sadness, fear, disgust, contempt and anger); and advanced emotions (frustration and confusion). The Emotient software detects and processes anonymous facial expressions of individuals and groups that the Glass wearer sees to determine an aggregate sentiment read-out; it does not store video or images.
