tactile paving; Braille block; textured ground surface indicator
Yellow raised blocks installed on sidewalks, train platforms, and public spaces to guide visually impaired people. Invented in Japan in 1965 and now used worldwide.
Cultural note
Invented by Seiichi Miyake in Okayama, Japan in 1965. The yellow color was chosen for high visibility. There are two types: dots (点状) for warnings (such as platform edges) and lines (線状) for directional guidance. In Japan, it is considered poor manners to stand on or block tactile paving.
