Producing non-verbal output for an embodied agent in an intelligent tutoring system

Abstract

This paper discusses how we can generate non-verbal output through an embodied agent from a user’s actions in an ITS. The most part of the present work is related to maintaining an emotional state for a virtual character. We present the basic emotional model we used for internal emotions management for the character. Then we follow with an overview of the agent’s environment followed by the role he is designed to play using our own system as a reference. We then give an overview of its internal architecture before we move on to what are the inputs taken by the system and how those are treated to modify the emotional model of the agent.
