Objective: This study proposes a personalized lighting system to enhance the affective quality of passengers' experience in a premium bus. Background: As concerns about user centered aspect increases in public transportation, this study considers passengers' seating postures as the cue to optimally related the behavioral patterns to their desired emotion. Method: Empirical test and user workshop were conducted to explore the personalized lighting in a premium bus. In an empirical test, 34 college students participated and their posture changes were measured with two angle joints- backrest and footrest. Eight types of given activity were narrowed down into four categories, and then during the user workshop, 26 college students explored and assessed the quality of lighting to best enhance affective experience for each of the activity category. Results: We found a noticeable difference across the activity types, and the changes were consistent among the participants in the case of the backrest. In the case of the footrest, however, the representative data were not found as the angle varied a lot individually. Based on the observation we derived four categories of activities: Focus, Casual, Relax, and Sleep. Individual variations were observed as height and sitting habits of participants varied. In total, there are 108 different types of emotional lighting collected, and seven patterns of light distribution were proposed. Conclusion: Passengers are willing to adjust their sitting postures by changing the angles of backrest and footrest, where we can make a good assumption of their desired behavior and emotion based on their postures. Based on empirical studies, we suggest four types of lighting that optimally fits to the frequent activities in a premium bus, such as focus, casual, relax, and sleep. Application: Furthermore, we expect advancement of user-centered lighting design by achieving emotional satisfaction not only in a public transportation but also in any personalized space.
