It's virtually pedagogical: pedagogical agents in mixed reality learning environments

Pedagogical Embodied Conversational Agents (PECA) that autonomously behave in mixed reality environments, respond to muti-modal input across computer networks, interact with human learners using context aware intelligence, and apply proven pedagogical techniques during instruction have the potential to improve and accelerate human learning performance anytime, anywhere, and at any-pace. This paper discusses the PECA Product Line Architecture (PPLA) model for building interactive pedagogical agent systems and discusses a prototype system from the architecture.
