Embodied Emotional Agent in Intelligent Training System

In this chapter we discuss how we have generated nonverbal output through an embodied agent, based on a user’s actions in an ITS. Our project has been principally concerned with maintaining an emotional state for a virtual character. Presented herein is the basic emotional model we used for the character’s internal emotion management through qualitative reasoning. We give an overview of the agent’s environment and describe the role the agent is designed to play, using our own system as a reference; next, we outline the agent’s internal architecture. In conclusion, we discuss the inputs taken by the system and how these are treated to modify the emotional model of the agent.
