Gender Preference Differences in Color Temperature Associated with LED Light Sources in the Autopilot Cabin

In an automated cockpit, the role changes from driver to passenger, with a greater focus on the in-cabin experience. The reasonable use of light sources will effectively improve the user cabin experience. In particular, we can effectively derive the preference for color temperature by the convergence of group selection for different groups of men and women.

In this study, systematic descriptive analysis, t-test, and one-way ANOVA were performed on the data yielded using questionnaires. The preference choices of 23 (11 male, 12 female) participants who came to China were studied under five different color temperature (CCT) lightings in the autopilot interior. The results demonstrated that there were disparities in terms of gender in the correlation of LED light sources in the autopilot cabin. Women preferred 3500K white light, and men preferred cooler than 5000K light during daytime in summer, while women preferred 3000K warm white light and men preferred 4000K cool white light during nighttime.

Moreover, passengers’ alertness, visual comfort, and preference also differed under different color temperature environment brightness. Meanwhile, passengers’ alertness, visual comfort, and preference were shown to have a significant positive correlation.
