Technology is beautiful, especially when it comes to the aid of the differently abled. For instance, with LeChal, visually impaired people can travel anywhere without guidance from others. LeChal is basically a smart shoe that harnesses the visually challenged’s heightened senses of touch. It enables them to travel by themselves with the help of vibrational patterns on their feet. This haptic-driven smart shoe has been produced by Secunderabad-based Ducere Technologies.
