Le Chal, a shoe that may replace the cane for a visually impaired person, was developed by Anirudh Sharma.

Le Chal, or "The Take-Me-There Shoe," uses a phone's GPS along with Google Maps to guide a visually impaired person to their destination using directional and proximity based vibrations. Currently the shoe is designed to interface with GPS-enabled Android phones, making this another great example of utilizing mobile technology to solve age-old problems in a practical and intuitive way.
