A high school student in Arunachal Pradesh has invented a unique pair of
goggles that uses ultrasound and infrared sensors to help the visually
impaired detect obstacles on their path. He was awarded the Dinanath
Pandey Smart Idea Innovation Award, APJ Abdul Kalam IGNITE Award for
inventing a gadget called Goggle for Blind (G4B).
This talk was given at a TEDx event using the TED conference format
but independently organized by a local community.
