text: STUDENT_NAMEI am usually a bit skeptical about new technologies like the Facial Action Coding System, but I am opened to the idea of new technology. In this case I support the value of using this technology to read students' emotional expressions. It is pretty interesting how the Facial Action Coding System (FACS) can determine the emotion someone is feeling by examining the muscle movements in the face. The FACS could be a very usefull tool in many ways in the near future.
