text: FACS also is not valuable because it is not diverse enough in its usage nor its abilities. Teachers and peers can easily spot emotions just as easily, and often more accurately, than this machine. As cited in paragraph five of the article, "In fact, we humans perform this same impressive 'calculation' every day." This would lead this invention's discovery to be unneeded and unneccesary, unless in it's applications of the distinguishment of the emotions of century old art pieces.
