Visually impaired people are finding more and more ways to aid their travels through the sighted world, but as technology improves their tools become less obvious, and in this case, more fashionable.
The Le Chal is a navigational device for the visually impaired that embeds a proximity sensor and directional actuator that delivers haptic feedback in your shoes. The system effectively allows the visually impaired to feel their way around obstacles via their feet, rather than an outstretched cane or a seeing eye dog. The device was concocted by Anirudh Sharma, a researcher at Hewlett-Packard Labs in Bangalore, India. You can see Sharma demonstrating how the shoes work in the video below.
