Hawk-Eye

As the Australian Open begins, the first tennis grand slam of the Asia Pacific, I am amazed at how much things have changed since the inception of what is called Hawk-Eye technology in the game's challenge system. When a shot is placed close to the line, raising doubts as to whether or not the shot placement was in or out, a player can challenge the call made by a line judge. Using hi-speed cameras placed around the court, the shot is digitally replayed to show the accuracy of the shot. It stands to show truth and fairness in what is called a gentleman's game.

Here's what the players have to say about the technology:

On another sport, following the football world cup of last year, there has been pressure from football fans for FIFA to introduce goal-line technology to ensure whether a shot crossed the goal line although it did not reach the back of the net. There was controversy that followed the proposal on its effectiveness and accuracy, and also as to how exactly it is to be applied.
