text: Often times, teachers use different teaching styles based on what allows their students to learn most effectively. With the Facial Action Coding System, computers could do so, too. For example, say you're reading an excerpt on the computer and it's not really on a topic that interests you, most students would immediately lose attentiveness to the reading. This is not a good thing, especially if the information was important, useful, or for a grade. But, with the Facial Action Coding System, this problem could be solved. The system could be used to spice up the learning, or keep the teaching style stays the same way if the student is staying attentive.
