Blind stick design / Blind staff

Blind stick design

When crossing the road, it is difficult for the blind to distinguish between the red light and the green light. When crossing the road again, they mostly comply with the crowd. This blind stick can detect the red light and the green light. When the red light is detected, the blind stick will send out a vibration to remind the blind. When the green light is detected, it will remind the blind to be passable.
