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.
