THIS CHALLENGE GOT ME ARRESTED

The Hawk-Eye system was developed as a replay system, originally for TV broadcast coverage. As such, it initially could not call ins and outs live.

The Hawk-Eye Innovations website [18] states that the system performs with an average error of 3. This is roughly equivalent to the fluff on the ball.

Hawk-Eye is currently developing a technology called 'Hawk-Eye Live', which will use the 10 cameras to call shots in or out in real time, with an 'out' call being signified by a speaker emitting an 'out' sound that emulates a human line judge.

The technology is currently in trials and is expected to be in place for the US Open. Currently, only clay court tournaments, notably the French Open being the only Grand Slam, are found to be generally free of Hawk-Eye technology due to marks left on the clay where the ball bounced to evidence a disputed line call.

Chair umpires are then required to get out of their seat and examine the mark on court with the player by his side to discuss the chair umpire's decision.

A key example of this was the number of challenges a player was permitted per set, which varied among events.

In an advantage set a set with no tiebreak players are allowed three unsuccessful challenges every 12 games.

The next scheduled event on the men and women's tour, the Sony Ericsson Open , was the first event to implement these new, standardized rules.

Hawk-Eye tracks the ball, and informs the referee if a ball fully crosses the goal line into the goal. The purpose of the system is to eliminate errors in assessing if a goal was scored.

The Hawk-Eye system was one of the systems trialed by the sport's governors prior to the change to the Laws of the Game that made GLT a permanent part of the game, [21] and it has been used in various competitions since then.

GLT is not compulsory and, owing to the cost of Hawk-Eye and its competitors, systems are only deployed in a few high-level competitions.

As of July [update] , licensed Hawk-Eye systems are installed at 96 stadiums. At the World Snooker Championship , the BBC used Hawk-Eye for the first time in its television coverage to show player views, particularly of potential snookers.

The BBC used to use the system sporadically, for instance in the Masters at Wembley the Hawk-Eye was at most used once or twice per frame.

In contrast to tennis, Hawk-Eye is never used in snooker to assist referees' decisions and primarily used to assist viewers in showing what the player is facing.

A trial took place in Croke Park on 2 April The double-header featured football between Dublin and Down and hurling between Dublin and Kilkenny.

Over the previous two seasons there had been many calls for the technology to be adopted, especially from Kildare fans, who saw two high-profile decisions go against their team in important games.

Hawk-Eye's use was intended to eliminate contentious scores. Use of Hawk-Eye was suspended during the All-Ireland hurling semi-finals on 18 August due to a human error during an Under hurling game between Limerick and Galway.

There have been no further incidents during the GAA. Hawk-Eye was introduced to a second venue, Semple Stadium , Thurles, in There is no TV screen at Semple: Hawk-Eye is now familiar to sport fans around the world for the views it brings into sports like cricket and tennis.

Although this new technology has for the most part been embraced, it has been criticised by from some quarters.

In the Wimbledon Championships men's singles final between Rafael Nadal and Roger Federer , a ball that appeared out was called in by 1 mm , a distance smaller than the advertised margin of error 3.

In , an article in a peer-reviewed journal [43] consolidated many of these doubts. The authors acknowledged the value of the system, but noted that it was probably fallible to some extent, and that its failure to depict a margin of error gave a spurious depiction of events.

The authors also argued that the probable limits to its accuracy were not acknowledged by players, officials, commentators or spectators.

They hypothesised that Hawk-Eye may struggle with predicting the trajectory of a cricket ball after bouncing: The use of the Hawk-Eye brand and simulation has been licensed to Codemasters for use in the video game Brian Lara International Cricket to make the game appear more like television coverage, and subsequently in Brian Lara International Cricket , Ashes Cricket and International Cricket A similar version of the system has since been incorporated into the Xbox version of Smash Court Tennis 3 , but it is not present in the PSP version of the game, although it does feature a normal challenge of the ball which does not use the Hawk-Eye feature.

In each frame sent from each camera, the system identifies the group of pixels which corresponds to the image of the ball. It then calculates for each frame the position of the ball by comparing its position on at least two of the physically separate cameras at the same instant in time.

A succession of frames builds up a record of the path along which the ball has travelled. It also "predicts" the future flight path of the ball and where it will interact with any of the playing area features already programmed into the database.

The system can also interpret these interactions to decide infringements of the rules of the game. The system generates a graphic image of the ball path and playing area, which means that information can be provided to judges, television viewers or coaching staff in near real-time.

On 14 June , a group of investors led by the Wisden Group bought the company, [6] who included Mark Getty , a member of the wealthy American family and business dynasty.

The acquisition was intended to strengthen Wisden's presence in cricket and allow it to enter tennis and other international sports, with Hawk-Eye working on implementing a system for basketball.

According to Hawk-Eye's website, the system produces much more data than that shown on television. Put up for sale in September , it was sold as a complete entity to Japanese electronic giant Sony in March It is used primarily by the majority of television networks to track the trajectory of balls in flight.

The third umpire was able to look at what the ball actually did up to the point when it hit the batsman, but could not look at the predicted flight of the ball after it hit the batsman.

Its major use in cricket broadcasting is in analysing leg before wicket decisions, where the likely path of the ball can be projected forward, through the batsman 's legs, to see if it would have hit the stumps.

Consultation of the third umpire, for conventional slow motion or Hawk-Eye, on leg before wicket decisions, is currently sanctioned in international cricket even though doubts remain about its accuracy.

At the end of an over, all six deliveries are often shown simultaneously to show a bowler's variations, such as slower deliveries, bouncers and leg-cutters.

A complete record of a bowler can also be shown over the course of a match. Batsmen also benefit from the analysis of Hawk-Eye, as a record can be brought up of the deliveries from which a batsman scored.

These are often shown as a 2-D silhouetted figure of a batsmen and colour-coded dots of the balls faced by the batsman.

Information such as the exact spot where the ball pitches or speed of the ball from the bowler's hand to gauge batsman reaction time can also help in post-match analysis.

In Serena Williams 's quarterfinal loss to Jennifer Capriati at the US Open, three line calls went against Williams in the final set, and Auto-Ref system was being tested during the match.

The Hopman Cup in Perth, Western Australia , was the first elite-level tennis tournament where players were allowed to challenge point-ending line calls, which were then reviewed by the referees using Hawk-Eye technology.

It used 10 cameras feeding information about ball position to the computers. Jamea Jackson was the first player to challenge a call using the system.

In March , at the Nasdaq Open in Miami, Hawk-Eye was used officially for the first time at a tennis tour event. Later that year, the US Open became the first grand-slam event to use the system during play, allowing players to challenge line calls.

The Australian Open was the first grand-slam tournament of to implement Hawk-Eye in challenges to line calls, where each tennis player in Rod Laver Arena was allowed two incorrect challenges per set and one additional challenge should a tiebreaker be played.

Defending champion Rafael Nadal accused the system of incorrectly declaring an out ball to be in following his exit. The umpire had called a ball out; when Mikhail Youzhny challenged the decision, Hawk-Eye said it was in by 3 mm.

Nadal could only shrug, saying that had this system been on clay, the mark would have clearly shown Hawk-Eye to be wrong.

The Wimbledon Championships also implemented the Hawk-Eye system as an officiating aid on Centre Court and Court 1, and each tennis player was allowed three incorrect challenges per set.

If the set produced a tiebreaker, each player was given an additional challenge. Additionally, in the event of a final set third set in women's or mixed matches, fifth set in men's matches , where there is no tiebreak, each player's number of challenges was reset to three if the game score reached 6—6, and again at 12— Additionally, during the finals of Federer against Rafael Nadal , Nadal challenged a shot which was called out.

Hawk-Eye showed the ball as in, just clipping the line. The reversal agitated Federer enough for him to request unsuccessfully that the umpire turn off the Hawk-Eye technology for the remainder of the match.

The Hawk-Eye system was not available when he challenged, likely due to a particularly pronounced shadow on the court.

As a result, the original call stood. The Hawk-Eye system indicated that the ball landed on the center of the line despite instant replay images showing that the ball was clearly out.

It was later revealed that the Hawk-Eye system had mistakenly picked up the second bounce, which was on the line, instead of the first bounce of the ball.

The Hawk-Eye system was developed as a replay system, originally for TV broadcast coverage. As such, it initially could not call ins and outs live.
