This study is an experimental study that allows subjects with anxiety symptoms to watch VR (3D) natural scenery and checks the screen therapy effect to see if there is an effect of emotional improvement.Before and after watching VR images, a clinical questionnaire was prepared, real-time brain waves (EEG) and heart rate bio-signal were recorded during video viewing, and analysis was performed through a post-EEG analysis program.As a result of the study, subjects with anxiety symptoms who watched VR natural scenery were able to confirm significant differences in negative emotions of the Panas scale in the self-reported response questionnaire.The scale is rest, recovery experience, vitality, all three factors in the prior real after all increased over.As a result of confirming the pre-post-change of the Relative Theta (RT) value, the EEG measurement data showed a significant difference between T3(.169) and T4(.161) afterwards rather than before.In particular, in the right (T4) than in the left (T3), the RT value increased post-mortem compared to the dictionary.In addition, it was found that Relative High Beta (RHB) decreased postmortem compared to the dictionary on the right (T4).The increase in Theta, which means improvement of anxiety symptoms after watching VR natural scenery, has the same meaning interpretation as the decrease in Beta waves.
