Rugby referees will soon be able to know when a team has scored a try, even if the ball is under a crowd of players.
Scientists have developed technology to track a ball’s precise location using low-frequency magnetic fields, when it is otherwise blocked from view.
A low-frequency transmitter is placed inside the ball and antennas around the pitch receive signals from the transmitter to monitor its every move.
American researchers at North Carolina State University and Carnegie Mellon University, Pennsylvania, have begun tests in American Football matches.
And Dr David Ricketts, lead researcher and associate professor of electrical and computer engineering at NCSU, said it’s ready for other sports.
‘This would work in rugby, as well as other sports – it’s just a matter of designing the right transmitter and making it robust for the specific sport,’ said Dr Ricketts.
‘Low frequency magnetic fields don’t interact very strongly with the human body, so they are not affected by the players on the field or the stadium environment.
‘This is part of what makes our new approach effective.’
