The white cane has been the mobility device of choice for blind people for some time now. But Abhinav Verma and his friends at IIT Kharagpur dared to think beyond: It was three years ago, as students, that they created a wearable sonar-based device, which can be worn like a glove. This was the first step towards removing the dependency of the blind on the white cane. The results they achieved were remarkable. Abhinav then decided to pursue the innovation even after college. He started a company called EmbroS and devoted his time to perfecting the product in terms of its efficiency and size. Abhinav then decided to pursue the innovation even after college. He started a company called EmbroS and devoted his time to perfecting the product in terms of its efficiency and size. After many trials and experiments, he developed Live Braille, a small and smart device that weighs just about 29 grams.

Live Braille has the ability to detect obstacles within a range of four metres. The device sends out 50 ultrasonic pulses a second to detect the obstacles and provides almost instantaneous haptic feedback to the user who can then avoid the obstructions and move forward. The device lets the user know where the obstacles are, how far they are, are they moving or not, what their texture is (hard, soft or sharp), and more.
