Sports has always been a 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 interpreting the games are altering with the surging 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 a precarious and exhausting part for any sports industry for years. An empiring interpretation has often been questioned for the judgements they make, which results in poor reputation in front of fans and creates the confusion in the fairness of the game.

Particular in the cricket, the umpires has faced the brutal bashing even if making the small mistake at the field. But, with the help of technology, both sports and technology has amalgamated to mitigate the traditional problems and get the efficacious outcomes. And here the DRS comes into picture, to minimize the inaccuracy. The DRS officially launched in the test match between the Nea Zealand & Pakistan.

DRS is used in every field of sports such as tennis, football, volleyball, cricket, badminton, rugby union, hurling to visually track the trajectory of the ball and display a most righteous path of a moving ball. Unlike to tennis and football, the DRS in cricket assists from video referee known as third umpire, and make the decision after analysing the video replays of the ball.

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

1.) Hawk eye 2.) Hot Spot

1.) Hawk-Eye:

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

Hawk-eye was the first company to perceive the FIFA GLT(Goal Line Technology) licence, the technology is classified 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.

Game viewers can watch the replay if the match organizers want to!

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:

Cricketers utilizes the Hawk-eye technology for making the foremost decisions 'Leg before Wicket' (LBW).

Six cameras track the trajectory of the ball as soon as the bowler hits it, including the bouncing, spinning, and swinging, and this tracking is then converted into a 3D image to show the 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 was bestowed in last 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 with 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 trace of the ball to real video footage.

Around 10 cameras are set up around the court to capture live image and also calculate the bounce trace 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 prepared frame by frame to show the ball’s trajectory
  • The VR image is created in less than 10 seconds

Goal-line technology in football:

Hawk-Eye was the first technology 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 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 utilized 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. However, the two infrared cameras are sufficient, generally four cameras are utilized to record the game consistently.  

The foremost principle is that the hotspot technology is using the "Thermal wave remote sensing"

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

In Conclusion,

Though the technology is reevaluating the games, it is apparent that the technology is used more frequently and become more accessible. With the usage of technology such as Hawkeye & Hot Spot, it is becoming largely accustomed in professional sport. 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 worldwide.
