Japan first began to use raised "bumps" in the floor as a guide for the blind and partially-sighted in 1967--the first country to do so.
They can now be found all over the country, in stations, public buildings, and on the sidewalk.
There is still no country-wide standard, but the basic designs are "dashes" to indicate direction, and "dots" to indicate warning, i.e. a change of direction, platform edge, etc.
A variety of materials are used, though a type of rubberised plastic is the most common. Metal is sometimes used.
I find them a fascinating source of composition in photographs.
