This study aims to develop a smart uniform with embedded luminescence for street cleaners to enhance visibility, safety, and long-term usability, informed by real users' opinions. It employed mixed-methods research comprising three phases: first, a pre-interview to identify existing problems; second, experiments to evaluate the visibility and durability of the technology embedded in smart uniforms during machine washing; and third, a post-survey and observation to assess user satisfaction regarding safety, long-term usability, and aesthetic aspects. Prototypes were developed to evaluate long-term usability and safety based on users' opinions. The findings indicated users desired long-term usage without the need for additional wear and highlighted concerns about the glare from light-emitting devices. The developed prototypes demonstrated long-term usability, remaining functional after more than 25 machine washes without reducing brightness or structural integrity. Regarding participant satisfaction, 83.5% of users were satisfied with the design, both aesthetically and functionally. This study offers a viable approach to developing user-centered designs incorporating light-emitting devices, which enhance visibility and provide aesthetic satisfaction while ensuring long-term usability. The results hold significant implications for future design research focused on vulnerable populations, emphasizing integrated satisfaction in terms of safety and long-term usability.
