Virtual reality (VR) refers to a computer-generated simulation in which a person can interact within an artificial three-dimensional environment using electronic devices, such as special goggles with a screen or gloves fitted with sensors. In this simulated artificial environment, the user is able to have a realistic-feeling experience.

Exposure therapy is one of the standard procedures for treating different types of mental illness. VR is slowly changing the way exposure therapy is being carried out for mentally ill patients, by providing a low cost, flexible and low-risk solution to treat mental illnesses. By providing new ways to keep the body relaxed and calm, VR also helps in treating anxiety and panic attacks.
