Abstract

EEG has been used to measure the emotion of amenity and discomfort in the interior space. EEG is limited to the experiment, because it is a equipment of contact type. However, Vibraimage can measure the emotion with a web camera. Because Vibraimage is a equipment of non-contact type, it is more suitable for the interior space than EEG. Therefor, it tries to find a correlation variable between EEG and Vibraimage to measure the human emotions. In this study, it were analyzed correlation of EEG and vibraimage due to variation of loudness 60[dB], 90[dB] and rosemary, jasmine scents. Check the health status of subjects who were selected 3 male students, and the period of this experiment was about months. The condition of the environmental test room was in temperature 25[$^{\circ}C$], relative humidity 50[RH%], air current speed 0.02[m/s] and illuminance 1000[lux]. It were analyzed correlation of twenty-three index of EEG(absolute ${\theta}$, relative ${\theta}$, absolute $S{\alpha}$, relative $S{\alpha}$, absolute ${\alpha}$, relative ${\alpha}$, absolute ${\beta}$, relative ${\beta}$, absolute $\gamma$, relative $\gamma$, absolute $F{\alpha}$, relative $F{\alpha}$, absolute SMR, relative SMR, $SMR/{\theta}$, $SMR+M{\beta}/{\theta}$, absolute $H{\beta}$, relative $H{\beta}$, $H{\beta}/{\alpha}$, absolute $M{\beta}$, relative $M{\beta}$, SEF50, ASEF50) and ten index of Vibraimage(Aggression, Stress, Tension/Anxiety, Suspect, Balance, Charm, Energy, Self regulation, Inhibition, Neuroticism). As a result, I was found that relative ${\gamma}$ index of EEG and neuroticism index of Vibraimage have a high correlation as (${\pm}$).414 and (${\pm}$).424.

실내공간에서 인간의 쾌적감 및 불쾌적감 등의 감성을 측정하기 위하여 뇌파(EEG)측정을 많이 사용하고 있으나, 뇌파(EEG)측정은 접촉식으로써 실험에 제한적이다. 그러나 진동이미지기술은 웹캠 카메라를 이용하여 인간의 감성을 측정할 수 있는 비접촉식 방법으로써 실내공간에 적용하기에 적합하다고 판단된다. 따라서 인간의 감성을 측정할 수 있는 접촉식인 뇌파(EEG)와 비접촉식인 진동이미지기술의 상관변수를 도출하고자 한다. 본 연구에서는 소리크기 60[dB] 및 90[dB]과 로즈마리 및 쟈스민 향기에 대한 피험자의 뇌파(EEG)와 진동이미지기술의 상관분석을 하였다. 피험자는 건강상태를 점검하여 대학생 남자 3명으로 선별하여 10회 반복 실험하였고, 실험기간은 약 한 달간 진행되었으며, 측정실의 조건은 온도 25[$^{\circ}C$], 상대습도 50[%], 조도 1.000[lux] 및 기류속도 0.02[m/sec]로 하였다. 뇌파(EEG) 23가지 지표(절대${\theta}$, 상대${\theta}$, 절대$S{\alpha}$, 상대$S{\alpha}$, 절대${\alpha}$, 상대${\alpha}$, 절대${\beta}$, 상대${\beta}$, 절대$\gamma$, 상대$\gamma$, 절대$F{\alpha}$, 상대$F{\alpha}$, 절대SMR, 상대SMR, $SMR/{\theta}$, $SMR+M{\beta}/{\theta}$, 절대$H{\beta}$, 상대$H{\beta}$, $H{\beta}/{\alpha}$, 절대$M{\beta}$, 상대$M{\beta}$, SEF50, ASEF50)와 진동이미지기술 10가지 지표(긴장/불안, 억제, 신경과민증, 밸런스, 매력, 자신감, 의심, 스트레스, 공격성, 에너지)를 상관 분석한 결과 뇌파(EEG)의 상대${\gamma}$파와 진동이미지기술의 신경과민증 지표가 (${\pm}$).414와 (${\pm}$).424로 높은 정적상관관계로 분석되었다.
