Stage Lighting Controller through Kansei Word Input

Abstract

This paper proposes a novel stage lighting controller in which users can change stage lighting effects by selecting impressions through Kansei words. First, the paper describes a mathematical model that calculates output brightness value of each stage light by emotions to be perceived by audiences and by light information that includes position/orientation, color, and shape of each stage light. Second, a subjective evaluation of stage lightings was carried out in which the subjects observed computer graphics of various stage lightings on a projector screen and answered perceived emotions. Third, a stage lighting system is proposed and implemented, which automatically calculates the output brightness value of each stage light. A user of the system only has to input desired emotions and the light information of each stage light. To evaluate the proposed system, a user study was carried out in which the subjects observed stage lightings generated by the system in a real stage set. The subjects gave positive feedbacks on the usefulness of the system.
