Watching an episode of "Japan's Top Inventions" on #NHK about tactile paving.
It's kind of depressing when you see the inventor, who had a #VisionImpaired friend, searching for solutions...and not asking the people his invention was meant for...at first.
Then noone was interested to invest in his solution so he even offered the "Ministry of Construction" that he would pay for the tiles and the installation.
The first #TactilePaving was installed in 1967...
