text: Because of the students facial expression, the computer can tell if the student is confused from a lesson in class. In the article "Making Mona Lisa Smile," Dr. Huang predicts "A classroom computer could recognize when a student is becoming confused or bored, then it could modify the lesson". If the computer could understand when the student is having a problem and can effectively fix that issue, then this could be the best way to teach. The use of reading students emotional expressions is valuable, because they can be taught better.
