Abstract
Background characters in virtual environments do not require the same amount of processing that is usually required by main characters, however we still want simulation that is more believable than random behavior. We describe an algorithm that generates behavior for background characters involved in conversation that supports dynamic changes to conversation group structure. We present an evaluation of this algorithm and make suggestions on how to further improve believability of the simulation.
