MIT engineer Rosalind Picard has developed glasses that read facial expressions

If you have ever watched the show Lie to Me, you know that their main character is a human lie detector that reads facial cues to tell if the person is lying or not. An electrical engineer at MIT has developed a new pair of reading glasses that uses a LED inside the frames to alert the wearer what the person they are talking is thinking based on facial expression.

Apparently, a study found that the average person is able to correctly identify the expressions on the faces of people that weren't acting 54% of the time. The software that the glasses uses to identify expression was accurate a slightly better 64% of the time. The glasses use a tiny camera that tracks 24 different feature points on a face along with the frequency and length of the expression.

Those feature points are then compared to a software database to identify six general facial states including thinking, agreeing, concentration, interested, confused, and disagreeing. The designers of the system hope to commercialize the glasses to help with things like determining what autistic children are thinking and helping people in the business world to determining how someone they are talking too is feeling.
