321 Guiding Blind Bricks / Reciprocal guiding bricks

321 Guiding Blind Bricks
321 Guiding Blind Bricks

As the blind walk on guiding bricks, they don’t have any mental preparation of encountering corners, stairs, and crossroads. It may make them anxious and get into danger. Therefore, we design 321 Guiding Blind Bricks.
It previously provides the mental preparation of road conditions. Before they encounter corners, stairs, or crossroads, the tactile lines on guiding bricks will transform from vertical to horizontal. Then the number of horizontal tactile lines is reduced from three to one brick by brick. Thus, the blind can have the mental preparation of road conditions and face them without any hesitation. It makes the blind walk at easy.
