A Study on the DISASTER Body Response Measurement System Using VR

Purpose: In this study, a number of industrial accidents occur, and occupational accidents caused by post-traumatic stress disorder. As a result of this occupational accident, many workers are suffering from post-traumatic stress disorder. Numerous industrial accidents occur every year, and the approval of occupational acci-dents caused by post-traumatic stress disorder is increasing. In particular, in the case of industrial accident trauma, workers are suffering from post-traumatic stress disorder that is more severe than other trauma patients in that workers are continuously re-exposed to the accident scene and re-experienced the accident. Method: Therefore, exposure treatment techniques for patients suffering industrial acci-dent trauma using VR(virtual reality) and measurement systems introduction was necessary. Using the disaster and disaster contents developed through this research and development, measure user reaction and secure data on the degree and timing of user reaction according to each accident event, so that it is possible to obtain reference data for appro-priate exposure setting according to the level of trauma became. As a methodology, a population composition for setting the exposure level and a hypothesis design for verifi-cation and a scenario design for hypothesis testing were established. In addition, the user reaction data for each accident event in the virtual experience was regarded as heart rate data, and a sensor and related system design that can measure data through the experiment were made, and the experiment was analyzed according to the scenario. Results: So, by measuring the heart rate of the experimenter using VR(virtual reality) to experience a traumatic disaster, Measuring heart rate variability(HRV) by disaster and environmental factors and observing stress chang-es. It is expected that it will be possible to obtain data on the extent to which the user reacts in a specific disaster by securing a measurement value of how and at what point in time the user reacts. Conclusion: This made it possible to analyze the post-traumatic disability later. In particular, through the re-sults of this experiment, it was possible to present the need for an indicator that can objectively evaluate the effec-tiveness of VR content for education and objective data of the indicator. In addition, a lot of data such as stability, movement, reaction, etc. were secured as basic indicators for the de-velopment of the “Crane VR Education Content” evaluation system.
