色弱者を対象とした円形視標の見やすさ評価に関する検討: カラーユニバーサルデザインのための測光色コントラスト評価図を用いた視認性推定法に関する研究(その2)

摘要

In the previous study, authors have proposed a method of handling luminous color contrast, and visibility evaluation experiments using in order to achieve color universal design. When luminance contrasts were zero, tendencies of results of protan and deutan types were similar with those of the common type with sightly greater range in red-green direction. However, when luminance and chromatiaty contrasts were changed simultaneously, it was seen that tendencies of results of common, protan, and deutan types differed greatly.%視環境設計において，視認性の確保は安全性や作業性の向上のため第一に必要とされる.公共空間等では，晴眼者だけでなく弱視者や高齢者，色弱者も想定した上で，サインや障害物の視認性が確保されなければならない.
