AHFE Open AccessPerceived Light Environment in Closed Space Based on EEG Analysis
Abstract
In order to study the impact of enclosed space lighting environment on human psychological perception and work efficiency, an experimental environment was constructed using VR (virtual reality) technology, and subjective perception and EEG signal acquisition experiments were conducted on the lighting environment in the virtual environment. Four working conditions were established by combining different color temperatures (3000 K, 5000 K) and different illuminance levels (300 lx, 1000 lx). The results show that: (1) The comprehensive evaluation score of low color temperature scenes in a narrow-confined sleeping space was 90% higher than that of high color temperature scenes. (2) Illumination and color temperature in a narrow-confined sleeping space had a certain impact on EEG, and showed a significant negative correlation with relaxation coefficient.
