Anang Tadar, a class 11 student from Arunachal Pradesh of Papumpare district has developed a device named G4B (Google For Blind) which will help the Blind people to detect the nearby object without any physical contacts using the principle of Echolocation as same as that used by Bats at night to find their prey.

The device has a microcontroller that uses two ultrasound sensors and an infrared sensor to detect an object in the surrounding by giving a vibration feedback. The two ultrasound sensors detect the Echo and send the vibration alert through coin vibration motor fitted on the two temples of the google.

He is now thinking to upgrade the device by replacing the ultrasound sensors with Laser range finder and adding GPS chip. According to him, GPS chip will give audible feedback when the button is pressed to help the visually impaired know their position and which direction they have to move to reach their destination.

He was honoured with the   Dinanath Pandey Smart Idea Award during the innovation festival organized by Regional Science Centre, National Council of Science Museums under the union ministry of culture.

He also participated in National Level Science Exhibition at Rashtrapati Bhawan, New Delhi, on March 6 where Honey Bee Network, which is in collaboration with NIF, Society for Research and Initiatives for Sustainable Technologies and Institutions (SRISTI), Global Youth Action Network (GYAN) and UNICEF were quite impressed with his innovation and are willing to launch G4B in the market and had asked Anang for creating few prototypes to test on the blind people.

Appreciating the brilliant innovation that is intended to make the life of visually impaired people easy, the Chief Minister of Arunachal Pradesh offered full financial support to him to develop the gadget.

His innovation will surely help the visually impaired person in the way they move around.
