text: Feedback from the Facial Action Coding System can be a great tool to teacher's mechanics or teaching habits in the classroom. This can be because this tool can detect more than a teacher can and also can produce more feedback then a regular teacher can, but don't get me wrong, teachers are wonderful. The text states," A classroom computer could recognize when a student is becoming confused or bored... Then it could modify the lesson, like an effective human instructor." This shows that computers can be very helpful. Dr. Huang has done a marvelous job with this design.
