Pedagogical embodied conversational agent

A virtual reality instructor that autonomously trains a human learner in network virtual environments, respond to muti-modal input across computer networks, and applies proven pedagogical techniques during instruction has the potential to improve human learning performance anytime, anywhere, and at anypace. Building virtual instructors, however, have challenged researchers because of multidisciplinary expertise required in areas such as education, cognitive science, sociology, artificial intelligence, 3D computer graphics, linguistics, and more. This paper discusses a model for building human computer interactive virtual instructor systems using an innovative, system/software architecture.
