“Lechal” Interactive Haptic Footwear by Krispian Lawrence and Anirudh Sharma, 2011
I have been following the progress of Lechal since couple of years. Lechal was first designed for visually challenged to provide haptic feedback of navigation. Lechal is now released for more generic use. The idea os Lechal is a wearable/detachable sole that you insert in your shoe. Lechal app tracks your motions and communicates with the sole in the show. It also gives you haptic feedback of direction and records various data.
