초록

본 연구는 뇌파 분석을 통해 면적이 다른 공간의 창면적비에 대한 사용자의 이완-각성 반응 차이를 확인하고, 이를 통해 건축 설계 시 참고할 수 있는 과학적 근거자료를 제시하기 위해 수행되었다. 이를 위해 VR(Virtual reality)과 건식 뇌파 장비를 이용하여 산후조리원 개별실 모델링 이미지 자극에 대한 뇌파실험을 수행하였으며, RAB 지표(베타파에 대한 알파파의 비율)를 활용하여 실험참여자의 뇌파데이터를 분석하였다.

This study was carried out to identify differences in users’ relaxation-arousal reaction to the window-to-wall ratio of spaces with differentareas through EEG analysis and suggest scientific data that can be used for architectural design. For this study, an EEG experiment ofmodeling image stimuli in individual rooms of a postpartum care center was performed using VR(Virtual Reality) and dry EEG equipment,and EEG data of the experiment participants were analyzed using RAB indicators(the ratio of alpha waves to beta waves). The study resultsare as follows. First, with regard to changes in the window-to-wall ratio applied to a minimum area, four channels with a window-to-wallratio of 30%, 70% and 100% showed statistically significant differences in relaxation-arousal reaction before and after stimulation, and theyall had arousal reaction. Second, with regard to changes in the window-to-wall ratio applied to a facility mean area, two channels with awindow-to-wall ratio of 70% and 100% showed statistically significant differences in relaxation-arousal reaction before and after stimulation,and they all had arousal reaction. Third, when examining whether the same window-to-wall ratio showed differences in relaxation-arousalreaction in spaces with different areas, four channels with a window-to-wall ratio of 0%, 30% and 100% showed statistically significantdifferences, which means even though the window-to-wall ratio is equal, relaxation-arousal reaction may vary depending on the area. Lastly,the analysis results displayed that for making users feel comfortable with individual rooms of a postpartum care center, there was a need toavoid a window-to-wall ratio of 30% and 70% and above when designing a minimum area close to 6.3㎡, and that there was a need toavoid a big window-to-wall ratio of 70% and above when designing a facility mean area close to 10.34㎡. In addition, it was found that awindow-to-wall ratio of 50% generated arousal reaction least in these two areas, which means a window-to-wall ratio of almost 50% canmake users feel comfortable.
