白杖, or "white cane," is a mobility tool primarily used by individuals who are visually impaired or blind. It serves multiple purposes, including helping users detect obstacles, changes in terrain, and providing a sense of spatial awareness. The white cane is often associated with independence and safety, allowing users to navigate their environment more confidently. In many countries, the white cane is also a symbol of accessibility and awareness for the visually impaired community. It is recognized as a tool that promotes inclusion and understanding, encouraging society to be more accommodating to the needs of individuals with visual disabilities.
