A uniform semantic-based access model for realtime interactive systems

This research presents a uniform semantic simulation state representation and access model for realtime interactive systems (RIS) in the field of Virtual, Augmented, and Mixed Reality. The role of this model is to provide a uniform interface to a centralized virtual world state, and simple mechanisms to manage all simulation components acting on it. It addresses the low maintainability and reusability of the traditional non-uniform world access schemes. The proposed model is based on two fundamental requirements: sharing a common simulation state and updating it via events. The state is structured around an entity-model, which is combined with a central registry that provides symbol-based semantic access.
