FIVE INVENTIONS FOR A BETTER WORLD: FOOT SOLE FOR BLIND

Anirudh Sharma’s Lechal system (note the Hindi le, chal) helps guide the blind to their destination. The system involves a haptic insole, which is connected to an Android app integrated with Google Maps, fitted to the inside of a shoe. Users are guided to their destination by a series of vibrations, which build in intensity as the wearer nears those points at which they have to take a turn. A proximity sensor in the front of the shoe also alerts wearers of obstacles, leaving their hands and hearing free to avoid dangers such as traffic.
