Which of the following is a common mobility aid for individuals with visual impairments?

White canes are a widely recognized mobility aid specifically designed for individuals with visual impairments. They serve multiple essential functions, including detecting obstacles, providing information about the person's environment, and allowing the individual to navigate safely. The use of a white cane helps enhance spatial awareness and mobility skills, empowering users to move more confidently in various settings. Moreover, the white cane is a symbol of independence for many in the visually impaired community, greatly assisting in orientation and mobility.

Hearing aids, pollution masks, and smart watches do not have the same specific function in aiding mobility for individuals with visual impairments. Hearing aids are designed to assist with hearing loss, pollution masks help filter air, and smart watches primarily serve as digital devices for communication and fitness tracking. They do not provide the tactile feedback or environmental awareness necessary for safe navigation that a white cane offers.
