Virtual prototyping techniques provide unique way of interacting with computer data and images. These removes the barriers of key board, monitor and mouse and allow user to experience the relity of a computer generated scene. This technology provides immersive, interactive, multi-sensory, viewer-centred, 3-dimensional computer generated environments and user gets a feeling of a moving ground inside and occupying a position in the computer-created world. Objects in the computer environment occupies space and the user navigates through the space as if it where the real environment. The images in the environment change positions as the user moves in the space such as they would change position in the real world. Sensory inputs are supplied that support the illusion that the user is a part of the computer environment. Thus virtual prototype technique offers a new and innovative way to interact with the complex data and designs and presents the opportunity to design in a 3-D environment.
