摘要：Many virtual reality applications, such as training, urban design or gaming are based on a richsemantic description of the environment. This paper describes a new representation of semanticvirtual worlds. Our model, called SVHsIEVs1should provide a consistent representation of thefollowing aspects: the simulated environment, its structure, and the knowledge items usingontology, interactions and tasks that virtual humans can perform in the environment. Our firstmain contribution is to show the influence of semantic virtual objects on the environment. Oursecond main contribution is to use these semantic informations to manage he tasks of eachvirtual object. We propose to define each task by a set of attributes and relationships, whichdetermines the links between attributes in tasks, and links between other tasks. The architecturehas been successfully tested in 3D dynamic environments for navigation in virtual urbanenvironments.
