Methods and technologies of cosmonaut rescue simulation in virtual environment systems

The paper presents original methods and approaches for modeling the process of cosmonaut rescue using a jetpack within virtual environment system VirSim developed at the SRISA RAS. Proposed solutions are based on modern technologies of virtual reality (VR), including Oculus Rift CV1 VR headset, Oculus Touch controllers and Manus Prime II VR gloves. For human interaction with a computer-synthesized environment, a virtual model of cosmonaut with space jetpack was developed, whose hands copy the movements of operator's real hands. Control of virtual jetpack is performed on the basis of operator impact on the elements of jetpack’s three-dimensional control panel by the hands of the cosmonaut model. To introduce this approach into virtual environment system, methods were developed for dynamics simulation and control of cosmonaut model, including implementation of its hand movement, operation of control panel and thrusters. Results obtained in the paper can be used to create training complex for teaching cosmonauts to rescue in case of accidental separation from the International Space Station. © 2021 National Research Nuclear University.
