text: There are many resaons so why I think that FACS should have not been invented to figure out the emotions of pictures or humans. One reason is that they have to begin by making a 3-D model of the face in order to figure out the emotions which I think is a waste of time and the use of the 3-D printer and because all fourty four major mucles in the 3-D printed model must move like human mucles. Also it says in the first paragraph that when they found the emotions of the Mona Lisa that they say " at least according to some new computer software" which means that theya re not one hundred percent sure.
