盲人交通指示器 / Blind traffic lights


This special device can distinguish the traffic lights and help the blind cross the street safely.
When the traffic lights turn red, the device will automatically shape to a convex triangular. When it’s
green, it will turn to a convex square, which can make the blind perceive the traffic lights
effectively.This device can reduce the potential risk while the blind can touch this
simple remider to cross the road.
