ABSTRACT
One barrier to creating truly intelligent autonomous virtual characters is the lack of common ground knowledge contained between the agent and its human interaction partner. Predefining this knowledge for the agent is infeasible so such agents generally can only interact within a limited task domain. This is particularly true for conversational agents, who must handle a wide range of topics. Rather than attempting to tackle the difficult problem of conversation, we instead create an environment where the common ground knowledge is the actions to perform in a virtual basketball game. These actions are not internally predefined, but instead extracted and imitated during interaction. Imitation is crucial because common ground can only be said to exist if there is evidence that the parties have this knowledge [Clark 1996].

It is based on the idea that local environmental influences are constantly sensed by one or more of an agent’s senses (sight, hearing, smell, etc.). The perception ...
