| In this paper, we verify influence of ingredients in indoor space to comfort using EEG. Questionnaire survey is currently a major method to research the comfort subjects feel. However, the values obtained from questionnaires mainly depend on how subjects feel when they fill in questionnaires. EEG quantitatively captures information on what they feel in real time. Therefore, we aim to measure the comfort in variable condition of indoor space by using EEG. The experiment was performed in an office and we calculated degree of comfort from obtained EEG. Then we quantitatively verify the effect of ingredients in indoor space to comfort using regression analysis. In the results, the intensity of illumination had a large influence on comfort in the predictive model. |
