Outline of Final Research Achievements

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. We conducted an experiment for verifying validity of the method on desk work. The experimental results show that the proposed method with illuminance fluctuation outperforms the conventional method with constant illuminance.
