AutoTutorAutoTutor is a computer tutor that helps students learn by holding a conversation in natural language. AutoTutor tracks the cognition and emotions of the student and responds in a manner that adapts to the student. AutoTutor has been developed to help students learn about physics and computer literacy. Emotions are recognized by the dialogue patterns, facial expressions, and body posture of the student.
