text: The Facial Action Coding System would be able to "recognize when a student is becoming confused or bored". This skill would be incredibly useful, as sometimes it can be hard to pick up on exactly what someone is feeling within an efficient time frame. Sometimes while teaching, it is difficult to focus on students emotions and the lesson all at the same time. However, the Facial Action Coding System would take over the task of recognizing emotion, thus allowing the teacher to focus on the lesson at hand. According to Dr. Huang, "Most human communication is nonverbal, including emotional communication". Being able to see all of these nonverbal queues would help teachers to see the level of engagement that each of their lessons creates, as well as help students that aren't engaged.
