STEP BASED GEOMETRY-BEHAVIOUR COLLABORATIVE DIGITAL PROTOTYPING FOR IT PRODUCTS AND SOME APPLICABLE CASE STUDIES

Abstract

For efficient design review, a unified 3D virtual prototyping tool is needed for designers where both the styling of a product′s exterior and GUI′s dynamic behaviour can be evaluated simultaneously. We developed a geometry-behaviour collaborative prototyping tool based on STEP (ISO10303) standards. The tool can be associated with the STEP AP203file of a 3D geometric model from 3DCAD, then the behaviour of the GUI can be defined according to the ‘STEP behaviour schema’ described by EXPRESS language. Finally, in our prototyping, the behaviour model can be mapped into the animation script of a particular Web3D format. The designers can fully examine the usability and functionality of the GUI using the working prototype on Web3D browser.
