The virtual reality is enabling its users to have the privilege and the advantage to look around the artificial world, move in the artificial world and to interact with the items, objects or features that can be seen on the screen or the googles designed for such innovation, and it can basically create an artificial sensory experiences to its users, like smell, touch, sight and hearing. Some of the common accessories and devices used for virtual reality, includes a projector screen, computer monitor, a virtual reality headset which is also known as HMD or head-mounted display, and the latest one, is the head-mounted googles with a screen in the eyes.

Several medical schools are using VR as their means of instructing and educating their patients who aspires to become a professional and efficient doctors someday, and this technology is enabling their students to interact in the artificial world with an artificial human body, which can provide their students the knowledge and skills that are important for their profession. Several other professionals and individuals who are using this innovation, includes paramedics, in which the students were given a scenario that can help them learn lifesaving skills without placing themselves and their patients at risks; the patients, in which this innovation can help them acquire knowledge about positive lifestyle choices, and to make positive changes about their health, and this is called as preventative medicine; PTSD or post-traumatic stress disorder patients, in which the patients can gain knowledge and skills in dealing with their phobias and the symptoms of their condition; the architects and construction industry, in which it enables them to design and test new buildings in an artificial environment; and the dentists, in which the students are shown a 3D set of teeth with a virtual dental chair. In general, the benefits that a user and the institution may obtain by using VR, are lesser time and money consumption, safety, realistic experiences, efficiency, the chance to use it remotely, and the ability to re-use the technology on a regular basis, or refresh of skills.
