Hawk-Eye – A Closer look

It is not new that innovations are increasingly helping referees from various sports around the world, and tennis is no different. One of the most know innovations in the game is the almost perfect system to review the judges’ calls: the Hawk-Eye.

How does it work?

The Hawk-Eye tracks and can even predict the ball’s movement using sensors and several high-performance video cameras scattered around the court, creating a very accurate 3D image. With the system, plays that go unnoticed by the naked eye or even in the standard recording can be solved through revisions. The Hawk-Eye, is not perfect, though. It has a small margin of error of 3.6 millimeters.

The arrival in tennis

The technology was first tested in tennis during the defeat of Serena Williams against Jennifer Capriati in the quarterfinals of the US Open 2004. With the help of the system, several mistakes were made by judge Mariana Alves, who ended up being excluded from the competition. The US Open 2006, which had Roger Federer and Maria Sharapova as winners, was the first Grand Slam to use the Hawk-Eye.

How the Hawk-Eye is improving every aspect of the sport

The Hawk-Eye is not just for referees and players during the game. In tennis, the reviews are displayed on the screens of the courts, causing a unique moment for the spectators of the match. TV stations also use the images to analyze the games and improve the broadcast as a whole. The system is also used by athletes and coaches to increase performance. With the help of technology, it is easier to generate statistics and analyze weaknesses through the various cameras.
Players, coaches, referees, and lovers of the modalities that rely on the system have had their experience improved.
