Thematic Area of product / prototype / service: 
Product: Assistive Technology for Independent Mobility of Visually Impaired Community
Company (if applicable): 
Torchit Electronics Private Limited
Description of the product/Prototype/service: 
285 million visually impaired across the globe face multiple problems in their daily lives ranging from day to day indoor and outdoor travel, to getting fair employment opportunities and even feeling left out in the society. Out of the 285 Million visually Impaired People worldwide. Of these visually impaired, about 90% of the world's visually impaired live in low-income settings. As per the WHO statistics, 21% of the blind population resides in India. Our product, Saarthi is an innovative product that can be used to sense the surroundings by visually impaired people, which will help them in independent mobility. Saarthi can be attached to the white cane and the user will be able to sense the obstacles through feedback in the form of a buzzing sound and vibrating sensations. A powerful battery and microcontroller have been used to make it more effective and long-lasting with the availability of three accurate ranges. The user can use the device with a cane to find directions & obstacles in unfamiliar territories, whilst the device can be used independently in familiar regions for obstacle detection. Saarthi comes with built-in detection sensors which help the user easily and accurately identify the surroundings for the person using the device. "Saarthi", provides 99.7% Obstacle Detection Accuracy, which makes most accurate in all possible setups including closed rooms (2 feet), outdoors - lobbies (4 feet) and streets & open areas (8 feet). Saarthi is an ergonomically designed, battery efficient device that can be used standalone or can be attached to any white cane. And most importantly, it is also the most affordable price, to make it available to any individual Visually Impaired to purchase (at USD 40)
