3. Conclusion
In this paper, the role that virtual reality can play in the design, particularly in the evaluation and user training was
introduced. Product designers and engineers require various tools that help them to quickly modify the shape,
style, size and functionality of a product. VR technology allows the designer to intuitively create and manipulate
the shape of complex freeform CAD models. The mass spring damper system introduced in this paper can be
used to incorporate any material properties in the virtual objects. The simulation studies can be used to
interactively design an optimal solution. The proposed methodology allows a designer to evaluate the design and
incorporate any changes that can enhance the functionality of the design. The VR environment can also be used
for user training. This can enhance the acceptability of the product when it is launched in the market. At the same
time, several users who are suffering from disabilities can be provided training in virtual reality environment.
