盲道设计 / Blind Brick

There are about 45 million blind persons in the world today. That is a big proportion. How to overcome
the difficulties in the blind persons’ lives is a worldwide problem. For example, when a blind man trav-
eling on a blind track, he does not know when to turn and where is the crossroads. The blind brick we
designed plays a role of warning, and it is equivalent to the yellow lights in the traffic lights. The design
that we just change the details would obviously improve the lives of the blind.
