Supporting Adaptive Virtual Environments with Intelligent Agents

Adaptive virtual environments have been developed aiming at generating 3D environments adapted to user´s necessities and interests. Navigation aid techniques and content adaptation improve user interaction in such environments. This article presents a system for supporting real time adaptive virtual environments. A multiagents architecture is used to manage contents updating in the virtual world according to user profile evolution. Its agents utilize the user model, the environment model and a 3D objects database for decision-making on the necessary updating. A manager agent is responsible to accompany the user´s actions through the user interface to collect information that may be used to update his/her profile. This agent also controls the communication between agents.
