Adaptive Virtual Reality Design Methodology

The article provides an integrated analysis of practical application of virtual reality (VR) in healthcare. Modern VR products have been created for the diagnosis and treatment of post-traumatic syndrome, Alzheimer's disease, alcohol dependence, phobic disorders, and teenage depression. Information on such products is limited to simple scenes, without adaptation to the user. The article shows a prospect for creating a virtual system with biological feedback. The proposed system is a set of portable and stationary devices for recording physiological signals and immersion into a virtual reality environment, as well as smart nodes for registration, processing, and decision-making to correct the user's mental state. Technologies for wire/wireless transfer of audio-visual and parametric information in virtual reality systems are discussed. The analyses include the features (advantages and disadvantages) of using virtual reality in conditions of optical information transfer, wireless protocols, and wire interfaces that provide user communication with virtual reality system and technical solutions.
