- Abstract
- By using EEG and HRV, subjects were estimated on their psychological and physiological reaction when reading psychrometric chart in 7 point century font, in an environmental test room in the condition of temperature 25[℃], relative humidity 50[RH%] , air current speed 0.02[m/sec], giving variation in illuminance to 0.1, 300, 600, 1000,1300 and 1600[lux]. As a result, it was at 1300[lux] that absolute α wave, SMR, SDNN were most vitalized, and also both sides α wave asymmetry index, SEF50, HRT, stress and fatigue degree were at the lowest. It was found that a certain illuminance which minimizes psychological stress and fatigue degree while enhancing concentration and task achievement stably does exist
