When the blind need someone’s help, they can use a cane which is equippied with a appealing light. Because they don’t know who is around them, they can press the button on the cane’s grip to project a green appealing sign on the ground. Besides, the button can make the cane have some sounds to attract pedestrians’ attention and make them come for helping the blind.
