"In the 1970s, researchers began to classify facial expressions using the Facial Action Coding System (FACS). FACS coding was a significant breakthrough in understanding human emotion but could be accomplished only via painstaking work performed by highly-trained individuals. Affdex®, Affectiva’s flagship product, brings automation and scale to FACS coding. Built on groundbreaking research out of MIT Media Labs, Affdex brings emotion analytics and insights into the 21st century." http://www.affectiva.com/technology/
