The overall system structure includes three major modules:

• The Prototype Interaction Editor (Practor),
• The Analysis and Evaluation module
• The Prototyping facility

The application content, is an external entity which belongs partially to ISW since the pure content (objects, lights, real-time graphics etc.) can be produced by a third party VR development tool.

ISW provides the interaction designer with the capability to use the Prototype Interaction Editor in order to construct the graphs that represent the interactive and training sessions of the final application. The workspace of the Prototype Interaction Editor is an abstraction of the virtual tutoring environment which is constructed. The actual objects contained into the final virtual environment have their own abstract representation into the workspace, enabling the designer to think and design in user terms.
