Description

Method and System for Virtual Reality-Based Stress Relief The present invention relates to a virtual reality-based stress relief method and system, and more specifically, to a system that provides stress relief content to a subject and analyzes the biosignals to analyze the cause of the stress relief-inducing content. In modern society, mental fatigue (stress) is increasing due to the diversification of human relationships, diseases, work intensity, and living and working environments. Long-term accumulated stress is leading to mental illnesses such as depression, insomnia, obsessive-compulsive disorder, and panic disorder, and is emerging as a serious social problem as social and economic costs are also rising rapidly. While most mental illnesses are treatable, the need for both professional counseling and medication places a significant time and financial burden on patients. Furthermore, if not addressed early, patients fall into a vicious cycle that makes treatment difficult; consequently, the importance of prevention and mental health management is continuously being highlighted. Therefore, to address this, active discussions are underway regarding how to effectively provide stress-relieving content for modern people using virtual reality and how to manage mental health through this.
