WHY VIRTUAL REALITY ENVIRONMENT ?WHY VIRTUAL REALITY ENVIRONMENT ?
•VR serves as a cost-effective problem-solving tool.
University of Maryland
•In Virtual Reality (VR), human-computer interface technology leverages the natural human capabilities.
•Today's interfaces (keyboard, mouse, monitor, etc.) force us to working within tight, unnatural, two-dimensional constraints.
•VR provides engineers with real-time 3D audio, visual & sensory perception in a more intuitive & natural manner.
•VR system lets the engineer experience data directly.
•In VR, engineers can look and move around/inside a virtual model or environment, drive through it, lift items, hear things & feel things.

The Glove has six small vibro-tactile stimulators on the fingers and the palm.
Each stimulator can be individually programmed to vary the strength of touch sensation.
