Description

Technical Field

[0001] The present invention relates to the technical field of sports psychology training, and in particular to an immersive stress resistance psychology training system and method based on VR technology. Background Art

[0002] Psychological stress is both a dynamic situation and an emotional response. The research and application of psychological training technology is not only used for psychological adjustment, but also to reveal the characteristics and mechanisms of user behavioral cognition and neurocognitive processes. Traditional anti-stress psychological training methods are still based on the actual environment and simple auditory, visual and other conditions to create conventional psychological simulation scenarios for psychological intervention and practice on users. Traditional psychological training methods require a single training time of about an hour or even longer, with a long training cycle, high time cost, single training form, weak interactivity, and generally low application efficiency.

[0003] At present, virtual reality (VR) technology uses computers to simulate a three-dimensional virtual world, providing users with simulations of vision and other senses, allowing users to observe things in three-dimensional space instantly and without restrictions. Research based on the use of VR technology for psychological training shows that using a high-fidelity virtual reality system to restore a real 3D environment can cause anxiety, so that the psychological resilience training system prepares users for the high-pressure environment of the real world. Existing systems based on VR technology and physiological parameter monitoring are mostly used for the diagnosis of mental illnesses and generally simulate real scenes in reality. The diagnosis results still rely on the subjective judgment of expert doctors. The disadvantages of these systems are that they only play an auxiliary role in expert diagnosis, the virtual scene environment is monotonous, the data collection channel is single, the training form is boring, and it is not easy to conduct real-time feedback analysis of user data. Summary of the invention
