Virtual reality is defined as computer-simulated environments which are able to replicate a virtual presence in places that exist in the real world. Most of the current virtual environments consist of primarily visual experiences, which are displayed through a computer monitor. There are some virtual reality simulations that have the capability to add extra sensory information, such as sound or tactile sensation. The simulated virtual reality environment is often designed to feel natural presenting a lifelike experience. This can be very beneficial, especially when used for training and simulations during pilot or combat preparation. It’s very difficult to manufacture a high-fidelity VR experience, in most part due to limits on computer processing strength, image resolution, and bandwidth. The hope is that these limitations will be overcome as related technologies gain power and become more cost-effective.
The concept of Virtual Reality extend prior to the rise of the computer, but development of modern virtual reality as we understand it has taken place in the past forty years. Virtual Reality
