Problem
Existing VR-based mental health treatments struggle to adapt VR contents to the user's psychological state, leading to potential worsening of mental conditions and difficulty in determining treatment progress or side effects.
Innovation Solution
A system and method that measures biological signals in real time, analyzes the user's psychological state, and dynamically adjusts VR contents to improve psychological stability by selecting and remodeling VR experiences based on user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VR exposure training is used to treat mental diseases, then the patient is trained to avoid the situation on his/her own, but the exposure training may rather maximize a user's sense of fear, thereby worsening the mental disease
Solution Approach 1:
The system dynamically adjusts VR content parameters in real-time based on measured biological signals. The VR modeling unit remodels VR contents according to the user's psychological state, changing elements such as scene complexity, object presence, and exposure intensity to optimize treatment effectiveness while preventing excessive fear responses.
Solution Approach 2:
The system implements continuous feedback loops by measuring biological signals (heart rate, skin conductance, respiratory rate) and using this data to adjust VR content. The biological signal analysis unit processes these signals to determine psychological state, which then feeds back to the VR modeling unit for real-time content adaptation, ensuring the treatment remains within safe fear thresholds.
2Ease of operation
If VR contents are provided without real-time analysis of user's psychological state, then the system is simpler to operate, but the system cannot reconstruct the VR contents according to the degree of the user's uneasiness, thereby having difficulties in determining the treatment progress
Solution Approach 1:
The system performs self-monitoring and self-adjustment by automatically measuring biological signals, analyzing psychological state, and remodeling VR contents without requiring manual intervention. The VR modeling unit autonomously reconstructs VR contents based on measured uneasiness levels, and the system automatically determines treatment progress through continuous biological signal analysis.
Solution Approach 2:
The system accelerates the treatment process by using biological signal analysis to quickly assess psychological state and rapidly adjust VR content parameters. This enables real-time reconstruction of VR contents according to user's uneasiness degree, significantly speeding up treatment adaptation compared to manual methods.
3Device complexity
If VR contents are not adjusted according to user's psychological state, then the device complexity is reduced, but the system cannot provide personalized treatment or discover side effects, thereby reducing treatment effectiveness
Solution Approach 1:
The system achieves multi-functionality by integrating biological signal measurement, psychological state analysis, and VR content reconstruction into a single unified platform. The VR modeling unit serves multiple purposes: providing personalized treatment, monitoring side effects, determining treatment progress, and automatically adjusting content parameters, all through one system architecture.
Solution Approach 2:
The system changes multiple VR content parameters simultaneously based on biological signal analysis, including scene characteristics, object properties, exposure duration, and intensity levels. The VR modeling unit remodels VR contents by adjusting these parameters according to the user's psychological state, enabling personalized treatment while maintaining manageable system complexity through automated parameter optimization.

AI summary
A system and method for providing VR (Virtual Reality) content for relation training to stabilize the psychological state of a user which models VR content suitable for the psychological state of the user, based on information of the user, providing the modeled VR contents to the user, analyzes the psychological state of the user based on the provided VR contents, changes the VR contents by reducing the output speed of the VR contents or reducing the change rate of an object, and provides the user with the VR contents remodeled through the change, thereby providing VR contents more suitable for the user.
