A haptic shoe receives signals from a GPS-enabled smartphone allows the blind and visually impaired to walk independently, giving directions and alerting to obstacles.Invented by Anirudh Sharma, this haptic technology system has been developed by Ducere Technologies and is being tested at the LV Prasad Eye Institute (LVPEI), a World Health Organization Collaborating Centre for Prevention of Blindness located in Hyderabad, India.The technology is named Le Chal, which means ‘take me along’ in Hindi
The shoes contain an electronic module that includes a vibrating unit, a chip and a removable and rechargeable battery.The shoes will lead the user to the desired destination by notifying him or her about the turns. A left or right turn would be indicated by a vibration on that particular side of the shoe. The shoes are designed to be used alongside a cane as they do not notify about every obstacle. This is because it would become very frustrating and disorienting for the user to be notified for each obstruction, as the roads in India tend to have many obstacles on the way. The vibration will only guide on the turns and show the route to the destination.
the shoes are available for around 100$ on lechal
