Blind fans listen to the WC action

RIO DE JANEIRO, July 6 (AFP): Two commentators sat in a broadcast booth at Rio de Janeiro's Maracana Stadium, put on their mics and looked down at the pitch before narrating a World Cup game for an exclusive audience.
As the teams arrived, they began giving detailed descriptions to a group of people sitting in the stands. All were blind and visually-impaired fans listening through short-range radio signals on their smartphones.
