A subsystem for reproducing immersive virtual simulators with biofeedback

The paper shows the process of designing and developing a subsystem for reproducing virtual simulators with biofeedback as a part of an instrumental complex for creating, reproducing and maintaining immersive virtual simulators with biofeedback (IVT with BFB). The playback subsystem of IWT with biofeedback allows launching and functioning of the developed simulators allowing virtual reality immersion and interaction with biofeedback equipment, within which the operator has access to the necessary tools for launching, managing and making changes. The proposed subsystem is part of a large software and hardware complex. Within the framework of design and development, the authors consider the interaction between the simulator, equipment and the playback subsystem while indicating the technical means used. The paper shows a set of implementation tools, taking into account applied systems and subsystems, which largely can deter-mine the workload of the entire system as a whole and provide a significantly new level of virtual simulator reproduction, which potentially contributes to increased comfort and efficiency for both the operator and the user. The developed software package can be used throughout the entire simulator operation period within its life cycle. Using this solution, a virtual simulator has been implemented to perform work at height, which helps testing a person for acrophobia (fear of heights) and preventing anxiety disorders, with the ability to change the parameters of the virtual environment depending on the user's state.
