3D Interaction Assistance through Context-awareness - A Semantic Reasoning Engine for Classic Virtual Environment

This work focuses on 3D interaction assistance by adding adaptivity depending on the tasks, the objectives, and the general interaction context. The context is modelled with Conceptual Graphs (CG) based on an ontology. Including CG in our scene manager (Virtools) allows us to add semantic information and to describe the available tools. Adaptation result from rules handled with a logic programming layer (Prolog+CG) included in the Amine platform. This project is a step towards Intelligent Virtual Environments, which proposes a hybrid solution by adding a separate semantic reasoning to classic environments. The first experiment automatically manages few modalities depending on the distance to objects, user movement, available tools and modalities.
