There is therefore an opportunity for technological assessment of driver physiological status to be applied in-car, hopefully reducing the incidence of potentially dangerous situations. As part of our long-term aim to develop such a system, we describe here the investigation of differential skin temperature measurement as a possible marker of a driverʼs stress level. In this study, after giving informed consent 25 healthy male (n= 18) & female (n= 7) subjects (26.8 ± 8.0 S.D. yrs) were investigated under environment-controlled conditions, whilst being subjected to simulated monotonous travel at constant speed on a test-course. We acquired physiological variables, including facialskin temperature which consists of truncaland peripheralskin temperatures (Ts) using thermography, beat-by-beat blood pressure (BP), cardiac output (CO), totalperipheralresistance (TPR), and normalized pulse volume (NPV) used as an indicator of localperipheralvascul ar tone. We then investigated the driverʼs reactivity in terms of skin temperatures with this background of cardiovascular haemodynamics. We found that the simulated monotonous driving produced a gradualdrop in peripheralT s following the driving stress, which, through interpretation of the TPR and NPV recordings, could be explained by peripheral sympathetic activation. On the other hand, the truncalT s was not influenced by the stress. These findings lead us to suggest that truncal-peripheraldifferentialT s could be used as a possible index indicative of the driverʼs stress. In fact, a significant correlation was confirmed between stress reference of BP and differential skin temperatures.., 金沢大学自然科学研究科}, pages = {163--174}, title = {差分顔面皮膚放射温度を用いた運転ストレス評価の試み : 単調運転ストレス負荷による基礎的検討}, volume = {48}, year = {2010} }
