APPLICATION OF VIRTURAL REALITY IN TRAINING ASTRONAUTS FOR SPACE OPERATIONS

摘要

This study focuses on the utility of virtual reality (VR) to ground-based training of astronauts in preparation forextravehicular activity (EVA). A VR simulation system for EVA is developed to integrate high-fidelity graphics, forcefeedbackand real-time computer simulation to achieve an immersive training environment. An experiment wasconducted to evaluate the system performance and its usability in an EVA task of space walking and payload retrieve inwhich two astronauts cooperate with each other. The experimental results demonstrate the effectiveness and usability ofthe system and the methods developed in this work.
