A Study on EEG measured when Changing Color of OLED Lighting

In order to investigate an evaluation method of lighting space by parameters of brain waves, EEG measurement and opinion test were done in a room with a color lighting. The color lighting with 64 Organic-LED panels was located in front of a subject, with a distance of 2.8 m and a height of 1 m. Colo...

Summary:In order to investigate an evaluation method of lighting space by parameters of brain waves, EEG measurement and opinion test were done in a room with a color lighting. The color lighting with 64 Organic-LED panels was located in front of a subject, with a distance of 2.8 m and a height of 1 m. Color was changed such as red, green, etc. with interval of 90 s. The opinion test about "Comfortableness", "Feeling", etc. was done with five-grade scale. Thirteen subjects (21-23 ages) provided written informed consent.In the case when color changed from green to red, mean opinion score (MOS) of "Comfortableness" decreased, and a correspondence with fast-alpha-wave power component was observed. In some cases, the relationship with MOS and the component was not observed depending on the color change. However, these results indicate the feasibility of using of EEG information to evaluate the lighting space.
