Sports being always the epicenter of the world whether it’s for magnification for cultural value or competitivity among nations, but as technology is coming into the spotlight, the traditional methodologies of evaluating the games are altering with the changing advancements. So one among them is DRS, which has changed the facets of analysis & judgements of sports.

Decision Review System (DRS):

Umpiring has always been an exhausting & tricky part of any sport for decades. An umpiring blunder has often decided the outcome of a vital encounter, resulting in fans questioning the fairness of the game.

But, with the help of technology, both sports and technology are merging to get efficacious outcomes.

With the world of sport constantly changing, the requirements for different technology is growing rapidly to capture effective gameplay and aid decisions made within the game.

Decision Review System (DRS) consists of two major components:-

1.) Hawk-Eye:

Hawk-Eye is a camera system that traces the trajectory of ball during the game.

Hawk-eye was the first company to receive a FIFA Goal Line Technology (GLT) license, the technology is now classed as the most accurate, reliable, and experienced provider of GLT.

What exactly is Goal-line technology?

Goal-line technology or GLT is the utilization of technology to identify if the ball has crossed the goal line or not. Match officials are the only in-persons to receive a signal.

Viewers can see a replay if the match organizers decide to show it.

Hawk-Eye Technology Services:

  • The Television Match Official (TMO) system will retain video replay to support officials.
  • Citing Commissioners and Referee Performance Reviewers will have real-time and retrospective access to video content.
  • Hawk-Eye will also contribute to real-time footage to the RWC 2019 Stats Loggers to ensure RWC analytics are more accurate and detailed than ever before.
  • In addition, match doctors will be able to access all camera angles to better review and diagnose incidents, however complete match footage will be available for teams to analyze their own performances, as well as upcoming opponents.

What sports is Hawk-Eye Technology used in?

It's impressive to see that so many sports are embracing technology to provide instant feedback on important decisions with their sports

How does hawk-eye technology work in different games?

It all depends on the sport, below are the most popular applications of Hawk-Eye technology

Leg before wicket (LBW) decisions in cricket:

Cricket uses Hawk-Eye for making the all-important ‘leg before wicket’ (LBW) decisions.

Six cameras track the ball as soon as the bowler releases it from their hand, including bouncing, spinning, and swinging, and this tracking is then converted into a 3D image to show a cricket pitch graphic.

It determines:

  • Where each ball pitches from specific bowlers,
  • How fast a ball traveled,
  • How much time a batsman has to react.

Electronic Line Calling in Tennis:

In tennis, Hawk-eye has been used since 2002, named Electronic Line Calling (ELC).

Hawk-Eye is accepted by the International Tennis Federation and has officially used in 80 tennis tournaments worldwide.

“You cannot be serious! how can it detect the ball up to 120 mph in a serve" Hawkeye's Ultra-Motion camera can work up to 340 frames per second to render both the trajectory and bounce mark of the ball to real video footage.

Up to 10 cameras are set up around the court to capture live images and also calculate bounce marks of the contact area of the ball during gameplay.

It determines:

  • 10 cameras are positioned around the court to track the ball
  • A 3D image is processed frame by frame to show the ball’s trajectory
  • The VR image is produced in less than 10 seconds

Goal-line technology in football:

Hawk-Eye was the first tech to be given a FIFA Goal Line Technology(GLT)license.

It’s already used in association football leagues/tournaments around the world, including the FIFA World Cup, Premier League, German Bundesliga, and Italian Serie A.

It determines:

  • They will always be able to track the ball’s location
  • detects when the ball crosses the goal line
  • Instant notification is sent to the referee’s watch
  • It’s millimeter accurate, so it’s the final say in any tricky decisions

2.) Hot Spot :

Hot Spot is an infrared imaging system used in cricket to determine whether the ball has hit the batsman, bat, or pad.

This hot spot technology was first introduced in cricket by a Melbourne based company, BBG Sports. Although two infrared cameras are enough, generally four infrared cameras are used to record the game continuously.

The basic principle the hot spot technology is using is "the thermal wave remote sensing"

When the ball or bat makes contact with the bat, pad, or the batsman, friction is generated. This friction causes heat, the temperature change is detected by the infrared imaging camera system. And that is how the contact zone is detected. This technology was first used in 2006 in Australia.


In Conclusion,

Though the technology is reforming the games, it is apparent that the technology is used more frequently and become more accessible. With the use of technology such as Hawkeye and Hot Spot, it is becoming largely accepted in professional sport. It can be argued that the use of new technologies is changing not only the way of training players and playing their sport, but also the whole experience of living and watching sport on TV across the globe.
