A RESEARCH OF THE FEATURES OF MULTIMEDIA AND PARAMETRITIC INFORMATION TRANSMISSION IN THE VIRTUAL REALITY SYSTEMS

Abstract

Background. The article is devoted to technologies and virtual reality systems as comprehensive solutions for immersion of the user into virtual reality using specialized devices and interfaces. Technologies for wire/wireless transfer of audio-visual and parametric information in virtual reality systems are discussed. The purpose of the article is to analyze and summarize advantages and disadvantages of modern facilities for multimedia and parametric information transmission used in virtual reality systems. Materials and methods. The research materials used the search method of scientific publications in Russian and international journals of scientific citation databases. Results. The paper analyzes the features (advantages and disadvantages) of using virtual reality in conditions of optical information transfer, wireless protocols (WiFi, Bluetooth, Wireless USB, LIDAR, ZigBee), and wire interfaces (Display Port, HDMI, USB) that provide user communication with virtual reality system. Virtual reality forms a new artificial real world transferred to the user via various wire/wireless (WiGig (802.11ad), WiFi 6 (802.11ax), WiHD (802.15.3c), and Display Port 2.0) interfaces, taking into account physiological, physical and psychometric indicators. Conclusions. Modern technical solutions should give impetus to the creation of adaptive virtual reality with a total immersion effect, when the user cannot distinguish a virtual world from real events.
