TIPPING POINT - ARCHITECTS OF THE FUTURE

1. Anirudh Sharma

Ingenuity on a shoe string

White sticks, dark glasses, a guide dog if they are lucky — the vision impaired have made do with crude tools to navigate the external world for decades. They have coped with danger and inconvenience, frustration and helplessness, and reconciled to a life of dependence. Now, something as routine as a shoe holds out the promise of safety, confidence and independence for millions of people.

The Innovator

A 24-YEAR-OLD Bengaluru boy who till recently worked at HP Labs, Sharma studied IT engineering and loved college because it brought him in contact with others equally passionate about design, tech and start-ups. Recently, he and like-minded innovator Krispian Lawrence, an electronics engineer from the University of Michigan, set up Ducere Technologies, a start-up based in Hyderabad that explores their shared passion for design, products and systems. “We aren’t in the business of making $1,000 shoes — that’s not what we do,” says Sharma. “We don’t want it to cost more than a good pair of shoes, for the idea is to maximise its reach among the millions who actually need it.”

The Challenge

WITH AN ENGINEERING degree and a passion for tinkering with novel interfaces — and systems that enable more natural forms of interaction than just keyboard and mouse — IT engineer Anirudh Sharma decided to turn his attention to finding a tech solution to the navigation challenges of the visually impaired. But he was clear he didn’t want to rely on their sense of hearing, which is what conventional aids often do. “I wanted a more intuitive design involving the sense of touch,” he says. To understand the challenges of navigating a world without vision, Sharma studied the commuting patterns of two visually impaired Bengaluru businessmen, Chandrashekhar Raju and Santosh Kejriwal.

The Idea

LE CHAL, AN INGENIOUS solution that ticks all the boxes — scalable, effective and cost-effective. The genius is in the simplicity of the idea — to get ‘haptic’ feedback (relating to the sense of touch) from a user’s shoes. The user spells out their destination on a GPS based phone that used a specially-designed app (any Android-based phone is fine); a combination of three ubiquitous technologies — Bluetooth, Google Maps and GPS do the rest. Once the GPS establishes the user’s location, Google Maps comes into play and finds directions for the destination. Bluetooth is used to establish ‘communication’ between the phone and shoes, and the user is on his way — vibrators on different sides of the shoes vibrate, indicating whether you need to go left, right or straight ahead.

There was another challenge — Sharma wasn’t an expert at making shoes; he also didn’t want to limit production to a particular brand or company. His design, therefore, needed to be compatible with generic shoes. The ingenuity of his solution is that it involves installing a circuit board in the heel and vibrators on each side of a shoe, and can be done on any existing pair, at a nominal cost of approximately Rs 2,000. It’s waterproof, and a proximity sensor in the front of the shoe offers an added bonus: alerting the user to obstacles up to 10 ft away.

The Impact

SHARMA WASN’T SURE Le Chal was a good idea till he built an prototype and showed it to people around him, which triggered their interest. He needn’t have doubted himself — the Indian edition of MIT’s magazine Technology Review recently named him Innovator of the Year under 35 for 2012; the award recognises those innovators whose work is likely to have the highest impact locally and globally.

The Way Forward

SHARMA IS HOPING to take a sabbatical once Le Chal’s tech specs are frozen and manufacturing initiated, and head to MIT for an inter-disciplinary course on Media Technologies. Long-term though, he intends for his research focus to stay the same: novel new media systems, prototyping and computer vision, though fields to which it is applied could vary from assistive technologies to sports to virtual reality.
