Radio waves can help the blind play football
Sridip Das, a final year student at Delhi's School of Planning and Architecture has designed equipment to help blind players play football.
It uses radio frequency identification and other technologies to emit sounds that enable the blind to play. Das spent time with the students of a blind school in Delhi to understand the problems they faced while playing the sport.
Das has designed a ball that has a small device fixed to it that continuously emits sound. Since not all the players are completely blind, everyone wears an eye mask while playing which has a reader that detects signals sent out by the way finders and poles installed at the corners of the ground.
When a player steps outside the playing area, the reader raises an alarm.The finders installed on the goalposts help players sense their way towards the goal line using sound.
