시각장애인을 배려한 지하철역 공공사인 컬러유니버설디자인 현황 분석 - 서울시와 도쿄, 요코마하시의 주요 역사의 비교를 중심으로

Abstract

This study intends to suggest methods to improve public sign colors for the visually impared people at subway stations. We investigated the color universal design of public signs at subway stations in Seoul, Tokyo, and Yokohama to explore how to advance the public sign design of Korea. To achieve this goal, we conducted a critical literature review about color universal design and then identified its characteristics by comparing the current color universal design in Korea and Japan. We carried out color sampling and analysis in both countries and described the issues and challenges. Compared with the sign colors in Korea, those in Japan showed higher luminosity contrast, thereby supporting the visually impaired people in a more adequate way. Finally, we proposed guidelines for designing of public sign color, expecting that visually impaired people will be better assisted everywhere in the world.
