Comfort/Discomfort Estimation based on Unconscious Reactions to Slight Illuminance Fluctuation

Abstract

We propose a method for estimating the user's comfort/discomfort in response to the lighting condition during desk work. We fluctuate the lighting condition slightly, and the user's comfort/discomfort is estimated according to unconscious behaviors induced by the illuminance fluctuation. The experimental results show that the proposed method with illuminance fluctuation outperforms the conventional method with constant illuminance.
