LABORATORIES Modelling, simulation and visualization have been used by engineers to analyse physical phenomena and design complex engineering problems(1). The same methodology is now being extended as virtual laboratories to conduct laboratory experiments on computer screens with necessary hardware and software to link the computers to the physical experimental set up. Virtual laboratories can be classified as recreative or interactive or immersive or collaborative. The hierarchy of virtual laboratory development is shown in Fig. 1. Page 17.30.7 Immersive and
