The hawk eye failure
The match was suspended after 15 minutes of play due to an unprecedented technical incident: in the Florida tournament the line judges are not present and are fully replaced by theHawk-Eye (hawk’s eye), a technology that uses sensors to check whether the ball lands in or out. The players returned to the locker room for a quarter of an hour and at the end the match was resumed with the line judges due to the impossibility of restoring the Hawkeye system.
What is the Hawk Eye
Hawk-Eye or Hawkeye is a slow motion system commonly used in tennis, cricket and other sports.
It consists of reproducing the trajectory of the ball and the path it has statistically followed. The system is based on the principle of triangulation using images recorded by at least four cameras positioned in different corners of the playing field. The system checks the videos and, based on predefined court templates and sport rules, decides whether the ball was valid or not.
The Hawk-Eye technology was first used by Channel 4 during a test match between England and Pakistan at Lord’s Cricket Ground in May 2001.
Employed since 2005 in tennis
In tennis it was introduced in the 2005 season in New York City and after checking eighty types of shots measured by the ITF (International Tennis Federation) high speed camera, it was approved for professional use.
For years the Hawkeye was just one more tool and tennis players could ask for a limited number of interventions. Then, in 2020, the Us Open 2020 was the first Grand Slam tournament to use the Hawk-Eye without the presence of the line judges, with the system instantly analyzing the game and connected to the loudspeaker that immediately called out. the ball left the field. However, it was used only in the secondary fields of the tournament, while in the two main fields there continued to be line judges. At the Australian Open 2021 this solution was used for the first time in all fields.
