Training agents: an architecture for reusability

During the last years, Intelligent Virtual Environments for Training have become a quite popular application of computer science to education. These systems involve very different technologies, ranging from computer graphics to artificial intelligence. However, little attention has been paid to software engineering issues, and most of these systems are developed in an ad-hoc way that does not allow the reuse of their components or even an easy modification of the application. We describe an agent-based software architecture that is intended to be easily extended and modified. Also, some experiments to test the suitability of the architecture are shown.
