IIT Delhi has developed a "smart cane" that helps the visually impaired detect above-the-knee obstructions from a distance of 3 metres.
Using modern sensor technology, the "SmartCane" enables users to detect objects in the path from three metres away. It costs Rs 3,000 - a fraction of the price for similar products available in global markets.
"This has huge implications not only for their safety but also for their dignity. The feeling of dependence often makes people feel vulnerable about unknown surroundings," IIT's Assistech co-founder Rohan Paul told PTI.
He said the trials found that SmartCane checks the visually impaired from banging into protrusions and has helped them walk with security and confidence.
"Field test reports show that users moved independently and safely with self-confidence using SmartCane," he added.
More than 300 people affected by blindness were involved in the development over the last eight years. Currently there are 150 users of SmartCane across the country.
Assistech is IIT Delhi's Lab which works on developing affordable assistive technology solutions for the visually impaired. It developed the technology for the cane.
Joint development was undertaken along with Phoenix Medical Systems, Chennai and Saksham Charitable Trust, Delhi to make this product a reality.
"We saw the difficulty of walking with the white cane, particularly when there are over hanging branches and raised signboards that cause injuries to the chest and face. Our objective was to develop a solution at an affordable cost that could increase the range of the white cane," Paul said.
Though similar products are available globally, they are expensive making it difficult for people to buy them.
"The average price point of navigation devices for the visually impaired is in the range of Rs 60,000-70,000. Our product however will cost only Rs 3,000 to ensure that people from all parts of the society can buy the product," Paul said, adding that it includes training and distribution charges.
According to the World Health Organisation, there are 37 million persons with blindness worldwide, of which about 90 per cent live in developing countries, including India.
India has 12 million people affected by blindness, the largest for any country in the world (2011 census data).
"I strongly believe role of organisations like IIT is to promote technology entrepreneurship so that the country develops a confidence in making quality products not only for India but also for rest of the world," IIT Delhi Department of Computer Science Deputy Director M Balakrishnan said.
