Contextual information plays a crucial role in nearly every
conversational setting. When people engage in conversations they rely
on what has previously been uttered or done in various ways. Some nonverbal
actions are ambiguous when viewed on their own. However, when
viewed in their context of use their meaning is obvious. Autonomous virtual
characters that perceive and react to events in conversations just like
humans do also need a comprehensive representation of this contextual
information. In this chapter we describe the design and implementation
of a comprehensive context model for virtual characters.
