摘要

The life of visually impaired people hasn't changed much even with the recent technological advances. At present trained guide-dogs are used by visually impaired to help them reach the final destination. But these aids are very expensive, more so in India. Further, technology aids using voice feedback based devices aren't helpful either to the blind as they block their inherent sense of hearing. They use their sense of hearing to avoid traffic, crowds, and obstacles. Anirudh Sharma has come up with another alternative, Le Chal, which is an unobtrusive navigation aid for the visually impaired.
