Probabilistic, layered and hierarchical animated agents using XML

Abstract

In a previous paper we generated animated agents and their behavior in XML. These agents were specified as FSMs. We make the system more useful by implementing probabilistic FSMs. We show how more interesting behaviors can be generated. Then, we make the system more flexible and structured by implementing layered FSMs and hierarchical FSMs. We show how both of these approaches, used independently or together, allow the user to write more complex behaviors.
