Aids for the Blind
Mood:  surprised
I just found out that there are little dots in Japanese paper bills so that blind people can feel the differnce between a 1,000, 5,000 and 10,000 yen note. Amazing

By the way, there are rough strips in the middle of many sidewalks so that a visually impaired person can follow them and stay in the middle of the walkway. There are vertical strips to indicate entering an intersection. Many of the crossing lights have audible sounds when it is safe for pedestrians to cross. These strips are a bit difficult to navigate on a bicycle but a small price to pay for the mobility it affords a person with a visual impairment.
