AutoTutor simulates human tutorial dialog with an animated conversational agent that helps students learn qualitative physics or computer literary by holding conversations in natural language. This project tracks the emotions and knowledge of the learner by dialogue patterns, speech intonation, facial expressions, and body movements. It integrates advances in discourse processes, education, multimedia, psycholinguistics, computational linguistics, and artificial intelligence. The project investigates strategies, processes, practices, and environments that are likely to assist the learners in interactive knowledge construction, particularly at deeper levels of comprehension and problem solving.
