text: The goal of a teacher, or anyone for that matter, is to succeed in their job. In a teacher's case it would be to grab the attention of the kids in their class so that the students can learn effectively. This software is useless because any great teacher can read their own class's facial expressions and modify their own lesson according to how a certain class reacts. What this means is that the Facial Action Coding System would be rendered as usless in the classroom because a great teacher can learn from their own class without the help from an external source such as the Facial Action Coding System.
