Abstract

This paper presents a system capable of automatically adding gestures to an embodied virtual character processing information from a simple text input. Gestures are generated based on the analysis of linguistic and contextual information of the input text. The system is embedded in the virtual world called second life and consists of an in world object and an off world server component that handles the analysis. Either a user controlled avatar or a non user controlled character can be used to display the gestures, that are timed with speech output from an Text-to-Speech system, and so show non verbal behavior without pushing the user to manually select it.
