text: The Facial Action Coding System would additionally allow for the computer to "modify the lesson, like an effective human instructor". This modification would allow for students who are bored and not engaged to better understand the lesson at hand. This would likely increase the learning that occurs within the classroom, as more students would have access to a lesson that made sense to them. Additionally, this eliminates the guess work of a teacher trying to come up with an effective lesson. The computer can do it for them. Thus, time can be used more efficiently when teaching students.
