13th Jun 2014Along with the teams, a lot of eyes will be on the Goal-line technology during World Cup and especially the critics will be watching it more closely.
FIFA has accepted the intrusion of technology after much apprehension and it looks like it is here to stay. It may well change the fortunes of the teams and more importantly it will save the referees from being the villains of the match.
While, for the Indians the use of technology is not nothing new, the goal-line technology is similar to Hawk-eye used in tennis or cricket. Unlike the two games the players cannot use the technology to challenge the decision of the referee.
An encrypted radio signal will be sent to the referee’s wristwatch when a goal has been scored. All the referee has to do look at his wrist and then decide whether to blow the whistle or not. It is not mandatory for the referee to declare it a goal, if the technology says so and he feels it isn’t.
It is so quick that within 0.5 seconds the referee will know what the technology says. There will be six cameras that track the ball’s position. The signal will use a triangulation method to pinpoint the precise location of the ball before releasing a radio message.
The system has already been sampled in England. It was pioneered in the Hampshire Senior Cup final between Eastleigh FC and AFC Totton, and by the FA in England’s international encounter with Belgium three weeks later.
FIFA approved it and was used during the Club World Cup in South Africa.
The infographic below, which comes by way of the Dell-supported blog Tech Page One, goes into further detail on FIFA's new goal line technology.
