This document presents information on virtual reality (VR), including its definition, uses, advantages, and disadvantages. VR can be achieved through a helmet and gloves that allow the user to interact with and manipulate computer-generated objects and environments. Some key uses of VR discussed are military training, sports/games, mental health treatment, medical training, and education. Advantages include creating realistic virtual worlds and environments to explore, while disadvantages include potential for addiction, health effects, and replacing reality. The feature of VR is that it is an evolving industry with improving hardware enabling revolutionary applications in gaming and simulations.

5. Virtual reality can be achieved by a helmet which covers the eyes and
ears and then sends visual and oral signals to the user. The user also
wears the special gloves which allows the user to manipulate computer
generated items.
Britain leads the world in VR research. Professor Robert Stone of Britain,
of the National Advanced Robotics Research Centre at Manchester
University was developing systems that can make human to reach
anywhere without taking them out of the office.
