In dark nights, pedestrians or those riding a bike often suffer collision and falling accidents due to the indiscernible road
when moving in a small alley or a dimly lit side street, and it is even more difficult for blind people with poor eyesight to
figure things out. The design sets a pressure sensor at the bottom of blind crutch, which allows the crutch to light up once
touching the ground during the walk of blind people, just like the light of fireflies. It brings convenience to both the blind
people and the passengers, which reminds us of the old story of "a blind man with lantern".
