The stress mdex was extracted from the compallson of heart rate, respiratIOn, GSR, EEG, ECG, and SKT measured from BIOPAC system Stress stimuli used m this research ale arithmetic stimulus and CPT(contmuous performance test) And then, it was comparatively analysed results of objective physiological signals and subjective estimates callymg out questionnaire.
As a result, in case of heart rate and GSR under stless situation, physiological signals of subject were shown slgmficant changes However, skill temperature was Impossible to obtam significant result because of vanous circumstance condition of subject and changeable body condition of subject self Particularly, Although It was confilmed stress state of subject through alpha wave band of EEG and respiration, skin temperatUie was not shown consistent tendency of change Consequently, stress mdex measu11ng stress level was extlacted from heart rate and GSR.
