Abstract

This paper presents a powerful animation engine for developing applications with embodied animated agents called Maxine. The engine, based on open source tools, allows management of scenes and virtual characters, and pays special attention to multimodal and emotional interaction with the user. Virtual actors are endowed with facial expressions, lip-synch, emotional voice, and they can vary their answers depending on their own emotional state and the relationship with the user during conversation. Maxine virtual agents have been used in several applications: a virtual presenter was employed in MaxinePPT, a specific application developed to allow non-programmers to create 3D presentations easily using classical PowerPoint presentations; a virtual character was also used as an interactive interface to communicate with and control a domotic environment; finally, an interactive pedagogical agent was used to simplify and improve the teaching and practice of Computer Graphics subjects.
