Haider Ali from Bhagalpur, Bihar, who is 100% visually impaired, says that he uses a smartphone and believes that a white cane is the most important mobility aid for blind people. He explains that traveling through places like railway stations, climbing stairs, boarding buses, or getting onto trains can be difficult and unsafe without a cane. In his view, a white cane is a blind person's support and guide. He also mentions that while technologies such as smart canes, smart glasses, and smartphones are available, these devices work best when used together with the necessary technology. He concludes by emphasizing that blind people should not travel without a white cane.
