Intelligent computerized tutor uses analysis of facial expressions

Researchers from University of Massachusetts Amherst (Beverly Park Woolf and Ivon M. Arroyo) and Arizona State University (Winslow Burleson) are developing intelligent computerized tutors in the Wayang Outpost project. The system incorporates a variety of sensors to detect students' emotions. For example, a camera is used to detect facial expression.

According to the Wayang Outpost article, the look on a student’s face and "how they tilt or hold their head" can indicate the level of interest in the task. An animated character is used to mirror the emotions of the user to provide feedback.
