The blind person's stick

Its main functions: detecting obstacles in front of the person (such as sidewalks, holes, stairs). Helping to understand the nature of the path (straight, sloped, stairs). Alerting others, especially drivers and pedestrians, to the presence of a blind person. How to use briefly: hold the light corner and move right and left at shoulder width. The tip of the cane precedes the person's steps to detect obstacles before reaching them.
