Immersive virtual reality is the perception of being physically present in the non-physical world. It is created by virtual reality systems, which surround users with videos, images, sounds and other stimuli that provides a complete realistic experience of an artificial environment. To perceive the digital environment to be physically real, all the five senses must be perceptually tricked. Such an effect is achieved through panoramic 3D displays, surround sound systems, haptic feedback, and smell and taste replications. Numerous immersive technologies, such as gestural controls, motion tracking, brain-computer interfaces and computer vision are used to track the user’s actions, movements and thoughts, in order to aid their interaction with the virtual environment.

The potential applications of the immersive virtual reality systems are numerous. They can be used for information visualization in industrial sectors to create augmented reality museums for educational purposes. In military, these systems can be used to create simulated environments to train pilots, soldiers and crisis response teams for situations, which are dangerous to train by using live equipment. Immersive virtual reality is also used to create realistic experience while playing games or watching movies, and in psychiatric care where the visualization of psychotic states can be utilized to gain increased understanding of a patient.
