Abstract. This paper presents a model for simulating cultural differences in the conversational behavior of virtual agents. The model provides parameters for differences in proxemics, gaze and overlap in turn taking. We present a review of literature on these factors and show results of a study where native speakers of North American English, Mexican Spanish and Arabic were asked to rate the realism of the simulations generated based on different cultural parameters with respect to their culture.

Abstract. In this paper we present an implementation of a embodied conversational agent that serves as a virtual tour guide in Second Life. We show how we combined the abilities of a conversational agent with navigation in the world and present some preliminary evaluation results.

For embodied agents to engage in realistic multiparty conversation, they must stand in appropriate places with respect to other agents and the environment. When these factors change, for example when an agent joins a conversation, the agents must dynamically move to a new location and/or orientation to accommodate. This paper presents an algorithm for simulating the movement of agents based on observed human behavior using techniques developed for pedestrian movement in crowd simulations. We extend a previous group conversation simulation to include an agent motion algorithm. We examine several test cases and show how the simulation generates results that mirror real-life conversation settings.
