Unified Modeling Language to Enhance the Specification of Discrete Event Systems for Virtual Reality Applications

This paper presents the utilization of UML (Unified Modeling Language) state diagrams and activity diagrams in order to model a discrete control system for a virtual reality (VR) application. Discrete control systems are utilized to control the behavior of a virtual model within a VR application. The common approach is to use a graphical notation, whose graphical elements represent states and messages. However, in a technical domain the discrete event system has to integrate technical simulations and engineering models. Furthermore, it needs to be flexible. An UML-based notation facilitates both. Changes are simple by replacing states and transitions of the diagrams. Engineering models are integrated by code templates, which are derived from the UML. This UML-bases notation has been tested. In summary, utilizing UML simplifies to keep track of the behavior models of virtual objects.
