This class-11 student has created special goggles for visually impaired and giving them a new ray of hope. Gadget guru Anang Tadar creates history in world of technology to help visually impaired people. His invention aims to make the lives of the blind easier.
Belonging to a family of farmers, Anang Tadar was more interested in researching things, unlike the boys of his age during his childhood.
Anang Tadar, a student studying civil engineering at Dr CV Raman University, grew up in the village, and was always curious about technology.
He loved taking apart machines and understanding how they worked. His curiosity became his teacher, and he started exploring the world of technology. By the time he was in eighth grade, he had a good understanding of basic electronics.
As he finished high school, he became interested in learning more about microcontrollers. It was his curiosity that helped him discover his true passion.
In 2016, he met a blind woman who inspired him to create G4B. He wants to help lots of visually impaired people with G4B and make their lives better. His goal is to make sure blind people can lead comfortable lives.
He asked volunteers if they ever accidentally bumped into things or people, and they said it happens every day, sometimes causing injuries. He believes every blind person should be able to use glasses. It took him a year to build a testable prototype.
However, creating the prototype was hard because he didn’t have enough money or support. He also didn’t know everything he needed to know and faced challenges.
He began researching and came across the principle of ‘echolocation’ which is used by bats – ultrasonic frequency waves are emitted from their mouth or the nose which get deflected the moment it senses an obstacle, and the bat hears the echo.
Using the same principle for Goggle for Blind, the innovator replicated it for the prototype where the wearer is alerted in advance if there is an obstacle in front of them, and helps them easily navigate the environment without the worry of bumping into things.
The goggle uses two ultrasound sensors on each of the lenses and an infrared sensor in the center, which helps in identifying any obstacle within a distance of two meters.
The 2017 innovation won Anang Tadar the National Grassroots Innovation Award and Traditional Knowledge Award 2019.
