text: The Facial Action Coding System (FACS) could really come of use to teachers attempting to get students to learn effectively. In paragraph 6 Dr. Huang says, "A classroom computer could recognize when a student is becoming confused or bored". This new technology could show teachers how effective their lesson was. It there are students who are bored, he/she could research or come up with new ways to get the kids engaged in lessons. FACS would also reveal confusion in students. Students sometimes get freaked about asking for further explainations because of how they might get judged. With FACS, teachers would already be able to see student that may be confused and be able to help them.
