The medical schools and aspiring professional doctors are using it as means of education and medical instruction, that can enable the students to obtain understanding and knowledge about the body of the human beings by enabling them to interact in an artificial setting. Other aspiring healthcare professional and other individuals, who are also using this innovation, includes dentists, in which the students are shown a 3D set of teeth with a virtual dental chair; 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; and the architects and construction industry, in which it enables them to design and test new buildings in an artificial environment. To summarize the benefits obtained by the users of VR, it includes less consumption of money, safety, realistic, efficiency, the chance to use it remotely, the ability to re-use the technology on a regular basis, or refresh of skills, and less consumption of time.
