Knowledge acquistion and management on virtual reality based design

Tools/philosophies such as PLM systems, Concurrent Engineering, Quality Function Deployment and Six Sigma are used by companies to deal with their product design problems. Use of computer graphics, particularly the interactive computer graphics, also found a significant role in today's product design and manufacturing efforts. Networked VR systems enable geographically dispersed collaborators to work on common projects. Low-cost scalable VR systems are available to simulate various design proposals before the physical prototypes are available. Today, theoretically it is known that the 3-dimensional (3D) interactive simulations are capable of replacing physical prototypes. Also, networked computers can provide realistic meeting conditions for long-distance collaborations. Both topics have been well studied by researchers. However, it is still not clear how this technology could be used effectively in real-life applications. The main focus of VR usage in collaborative design reviews and product assessment problems have been the visualization of information in both textual and graphical forms. Computer controlled visualization and communication systems on the other hand have greater potentials then their current usages. Design of intelligent assessment tools that observe and analyze the interaction between user and virtual scene or among users and their interactions with the virtual scene is relatively new topic in the literature. The present research program focuses on the development of Supervisory Support Systems to be embedded in VR based product design/testing and collaborative meeting systems. Particularly, User behaviour assessment, Management of collaborative VR and finally the Engineering change management topics will be investigated.
