WHAT IS A VIRTUAL REALITY?
Virtual reality (VR), also known as immersive multimedia or computer-simulated reality, it is a computer technology that replicates an environment, real or imagined, and simulates a user’s physical presence in a way that it allows the user to interact with the virtual environment. Virtual reality artificially creates a sensory experience, which can include sight, touch, hearing, and smell.
Most up-to-date virtual realities are displayed on an HD VR special stereoscopic displays, and some simulations include additional sensory information and focus on real sound through speakers or headphones targeted towards VR users. Virtual reality covers remote communication environments which provide virtual presence of users with the concepts of telepresence or a virtual artifact (VA) either through the use of standard input devices such as a keyboard and a mouse or through multimodal devices such as a wired glove or omnidirectional treadmills. The immersive environment can be similar to the real world in order to create a lifelike experience—for example, in simulations for pilot or combat training.
