Virtual reality

A) Virtual reality exposure therapy
Since the 20th century, people continue to explore the usefulness of virtual reality technology in social life, virtual reality technology and people have a very strong interaction, it requires a human operator computers for information collection, after transmitting these data to simulate real sense device (Liangzhi, 2019) that in order to provide unlimited space for imagination and enhance the user visual, auditory, tactile and other sensory experiences in real space is limited for the user. Virtual reality exposure method is a non-traditional means of rehabilitation virtual reality technology within the scope of a study carried out by treatment of virtual reality technology on human mental disorders such as anxiety and phobias. The current therapy for the treatment of humans without side effects and can be used as an adjunct to conventional therapy, compared to the human Conservative waiting for treatment or conventional therapy, virtual reality exposure method can effectively improve the mental state of mankind have mental illness.

In terms of social anxiety, virtual reality exposure therapy provides patients with active rehabilitation guidance,and social anxiety disorder refers to personal autonomy to generate persistent social passivity and apparent fear (Xi, et al, 2017.). In one trial, Anderson et al. (2013) for patients of different races social anxiety disorder on the results of the investigation virtual reality treatment and collection and treatment of patients with the disease statistics within a year. Eventually they came up with exposure treatments to significantly alleviate and improve patients’ social anxiety.In addition, in another survey experiment on the exposure of virtual reality to the treatment of social anxiety, the community took two equal numbers of young people with social anxiety and those without it to test the virtual environment.Parrish et al. (2016) analyzed the pain levels and acceptance of virtual reality exposure treatment in youths of two mental states in different scenarios; after discussion and analysis, they agreed that this treatment method is feasible . Thus available, patients often have social phobia surrounding environment and things behave emotional and very sensitive, such as crowded places tend to their spiritual self appear extreme discomfort, but treatment can collect patient information through virtual reality exposure design personalized treatment; it can not only provide the most appropriate patient care environment, patients and induce mental relaxation and active treatment is still to some extent.

The experimental data of Fernández-Álvarez, J. et al. (2019) show that virtual reality exposure therapy can be used as an adjunct to traditional therapies and can treat claustrophobia. In order to prove this, they performed virtual reality exposure treatment for middle-aged female patients with claustrophobia according to the degree of fear of closed spaces. After statistics, the patients’ claustrophobia was effectively controlled and They have a lower rate of deterioration than patients who are waiting for treatment. Experimental study on the current view, virtual reality exposure method is to human health and without side effects, it belongs to virtual reality technology, the human body does not have a substantial attack or injury.Compared with the transmission therapy method, patients with mental illness often need to contact with real things, such as taking psychotherapeutics, limited activity space, passive contact with doctors, etc., and these are in the process of treating patients’ spirit At the same time, it increases the pressure to face reality. The advantage of virtual reality technology is that it can give the user an environment that can be created and adjusted, which will relax the patient’s senses. Through computer programs, virtual reality can be used to simulate and predict the deteriorating factors of anxiety patients during treatment and change the plan in time to obtain a lower rate of deterioration. While traditional treatments for geographical space limitations, but it does have a solid knowledge of the system and test mature experience, which is positive in the development and testing phase of the virtual reality exposure therapy are lacking, but for the case of harmless under the virtual reality and the combination of traditional treatment for the patient to bring effective treatment is the best means of treatment of mental illness.

At present, the virtual reality devices on the market are mainly handles and helmets, but just as complex operating procedures have evolved easily during the development of computers; virtual reality devices will gain a lot of demand in the market after the popularization. And it will generate competition between devices and promote innovation in independent device research and development: the initial heavy volume will gradually become thin and light-helmets and glasses have evolved into positive contact lenses, and touch gloves are equipped with voice instructions to replace the handle. The modern network is updated quickly, so the simplified appearance of the device and the built-in precision adjustment have a great chance to appear in the near future.
