text: Many people learn in a different way. Some students are more effectively taught by learning visually, others hands-on, and some verbally. The Facial Action Coding system could recognize these based on students facial expressions. If the student is looking focused while seeing a diagram, the system could see they're a visual learner, and keep teaching the topic in that way. Otherwise if that doesn't work, the system could see if the student's emotions would change based on if they could listen to the information instead of reading.
