text: The FACS can improve the classes and the classrooms. It can also help set a better stage for teaching. This can produce ideas that people can bring to the classroom to seem more inviting and get more students that want to learn and can be excited while learning. The text shows that the FACS detects emotions that can be received by teachers and from there they can modify their teaching or better yet make the classroom and better and a enthusiatic place to learn. The FACS is very useful and detects emotions very well. The text also states," Using video imagery, the new emotion-recognition software tracks these facial movements-in a real face or in the painted face of Mona LIsa. By weighting the different units, the software can even identify mixed emotions (as in da Vinci's masterpiece). Each expression is compared against a neutral face (showing no emotion)." This just shows how outstanding the FACS is and how useful it can become within schools throughout the world.
