A Design Proposition for Interactive Virtual Tutors in an Informed Environment

This paper introduces a new research work that aims to improve embodied conversational agents with tutor behavior by endowing them with the capability to generate feedback in pedagogical interactions with learners. The virtual agent feedback and the interpretation of the user's feedback are based on the knowledge of the environment (informed virtual environment), the interaction and the pedagogical strategies structured around classical intelligent tutoring system models. We present our first steps to implement our proposed architecture based on a model of informed virtual environment. We also describe the ideas that will guide the design of the Tutor Behavior. The planned evaluation method and a first application are also presented.
