Model-Based design of virtual environment behavior

Designing and building Virtual Environments (VEs) has never been an easy task and it is therefore often performed by experts in the field. This problem arises even more when it comes to the design of behavior. To address this issue, an model-based approach called VR-WISE has been developed. This approach aims at making the design of VEs more accessible to users without or with little background in VE development. This means that the VE is specified by means of high-level models from which the actual VE can be generated. The purpose of this paper is twofold. Firstly, the design environment, supporting the approach, is described. We show how the models can be created in a graphical way. We also discuss the ”Verbalizer”. This module provides a natural language interface for the models, which enhances the intuitiveness of the specification. Secondly, we explain how behavior models can be specified.
