Perfect eyes are a gift that not all of us have. But technology is making it easier for the blind and visually impaired individuals to live their lives more comfortably. Take LeChal for instance. This is a smart shoe with a smartphone app that provides haptic feedback to help the wearer reach his/her destination. The companion smartphone app for this shoe allows you to enter your destination information to generate commands for the shoe.
LeChal provides navigation-assistance in an unobtrusive fashion. It lets users feel the directional and proximity information through vibrations. A pretty interesting idea by Anirudh Sharma.
