A new ‘social x-ray’ glasses concept dreamed up by Rosalind Picard from the Massachusetts Institute of Technology can identify human expressions, including whether someone is thinking, agreeing, disagreeing or confused.
A tiny camera inside the glasses works by tracking certain points on a person’s face which it then runs through special software. This software compares what’s going on at each point to a big database of faces and known expressions. The glasses then somehow tell you which kind of expression the person has.
You’d imagine that most people can pick up on these kinds of social cues automatically, but according to New Scientist we often miss important expressions because they’re so small and quick. The glasses could also be a huge help to people that find it hard to understand different expressions, like those living with autism.
