AVACHAT: a new comic-based chat system for virtual avatars

We propose AVACHAT, a new comic-stylized communication interface for avatar agents. We show that the 3-D word balloon could be successfully exploited to depict chat dialogues and the atmosphere of groups talking, such as cheerful laughing or loud quarrelling without adding any multimedia functions. Finally, we propose a new data structure to manage the chat dialogues among virtual avatars. It can be used to reconstruct the social-graph for chat agents in a virtual world.
