Comparison of Psychological Evaluation of KANSEI Lighting Using Large and Small Numbers of Subjects

Abstract

It is an important issue whether the results of psychological experiments targeting a small number of people can be extended to a large number of people. We are conducting joint research between the university and the company on KANSEI lighting that combines glass art and lighting. About 1, 800 visitors were asked to evaluate the developed KANSEI lighting at an exhibition intended for the general public. We used the evaluation items that had already been conducted on a small number of people. Therefore, the results of both experiments could be compared. In this paper, we report the results of comparing an evaluation experiment with a large number of people and that with a small number of subjects.
