text: The first reason why the use of the FACS within the classroom would not be valuable is due to the inability of the software to understand verbal emotion. When a student is confused and or emotional about a topic, often they will express this through verbal communication. The FACS is not able to register this kind of emotion, at least not this early in it's development. As cited in paragraph six of the article, " 'Most human communication is nonverbal, including emotional communication,' notes Dr. Huang. 'So computers will need to understand that, too.' " This statement also brings about the issue of emotional expression not on the face, including body language and stature. These reasons defend the idea that FACS is not a valuable software for the classroom.
