text: Another interesting thing that they discovered was that Dr. Paul Eckman was the creator of FACS (Facial Action Coding System). He had classified six basic emotions- happiness, surprise, anger, disgust, fear, and sadness. It also associated each with characterestic movements of the facial muscles. They invented somethIng else called video imagery, the new emotion software is that they track facial movement. As you can see its so easy to see their emotions or how they feel. They even show different weighting of units.
