text: The last way in which FACS can greatly improve the teaching environment in schools is by recognizing when a student is depressed or sad. FACS can detect facial expressions on students faces and determine if they may be going through trouble or are depressed. As stated on pargraph six, "Most human communication is nonverbal, including emotional communication". FACS could recognize when a student is not okay so that teachers can the help those students who may need help, wether that is emotional help or help with school work. FACS could even help save lifes by getting help to students who may be contemplaiting suicide.
