Recognition of human mood, alertness and comfort under the influence of indoor lighting using physiological features

Illuminance and correlated colour temperature (CCT) have been reported to be closely related to human mood, alertness, and comfort. In this dataset, we conducted light experiments at six illuminance levels of functional lighting (300, 400, 500, 600, 700, and 800lx) and four typical CCT levels (3000, 4000, 5000, and 6000K) to analyse the light effects on users’ mood, alertness, and visual comfort. Subjective feelings under the influence of the light environment can be evaluated through columns of physiological features extracted from electrocardiogram (ECG), electrodermal activity (EDA), skin temperature (SKT) and blood oxygen saturation (SpO2) data.
