This is the first time in table tennis history, ITTF used the “Hawk-Eye” technology in an international competition.

This will be great news for many players! And also important news for players around the world!

If you are relying on “tricky serve”, or “illegal serve”, watch out! This could be a game-changer!

TTR Hawk-Eye Technology in Table Tennis

Hawk-Eye technology, or also called “Table Tennis Review” TTR by ITTF, is first implemented in December 2019.

TTR is developed by RigourTech Technology Company.

For the first time in an ITTF tournament, athletes can review referees’ decisions with the help of review technology. Table Tennis Review (TTR) technology is similar to the Hawk-Eye technology in tennis and a number of other sports.

TTR technology is applied at the 2019 World Tour Grand Final, held from 12-15 December in Zhengzhou, China.

Why using TTR Hawk-Eye?

The ITTF is constantly improving and modernizing table tennis and TTR Hawk-Eye technology will bring about positive changes

Hawk-Eye will provide a database that helps to solve uncertain cases, leading to decisions, possible inaccuracies of arbitration or controversial decisions

If the player has doubts about the referee’s decision, then they can challenge the Hawk-Eye system.

If we are able to reduce the human error or uncertainty, which can naturally occur in all sports, through a fair, transparent and effective system, we believe this will benefit the players, fans, and officials themselves, as has been achieved in a number of sports already.” – Vicky Eleftheriade, ITTF Competition Director

This new technology will help the referees to make a decision and give an accurate score.

What is TTR Hawk-Eye?

TTR is the ball trajectory tracking system, and camera review technology, developed by RigourTech Technology Company.

With the help of high-precision ball trajectory tracking technology, it is possible to replay the moment when a complaint is needed immediately and be reviewed by a match supervisor/ umpire who has the authority to change the decision.

Initial identification based on video evidence.

ITTF chose RigourTech after the bidding process in August 2019 and successfully tested for 3 days backstage at Men’s World Cup 2019.

Hawk-Eye in other Sports

Hawk-Eye ball tracking and Reviewing system are not new.

It has been used in many other sports such as cricket, tennis, football, badminton, hurling, rugby union, volleyball, to visually track the trajectory of the ball.

The video assistant referee (VAR) is used in football and is a great success.

FIFA officially approved the use of VAR for the 2018 FIFA World Cup.

So why not Table Tennis?

For me, it’s too late! We should apply this technology sooner!, said EmRatThich

In 2001, the technology was first used for Cricket.

In 2006, then it is used officially for the first time at a tennis tour event.

12 Ways to use TTR Hawk-Eye

The TTR technology is provided by ITTF so that the athletes have the right to review the referee’s decision that they think is incorrect. With high-precision technology, the time to appeal is immediately replayed and reviewed by a video slow-motion monitor who has the authority to change the original decision based on evidence.

There are 12 examples that you can use TTR technology to track the ball trajectories such as:

How to use TTR?

What is the TTR Procedure? And how to use if you a table tennis player. ITTF has made some laws, regulations to use TTR.

  • Players are always informed about TTR technology before the match starts.
  • Players who need to appeal may request TTR technology by saying “TTR” or “Review”.
  • Claims to use TTR technology must be made as soon as possible, immediately after the referee announced the score and before the start of the next ball.
  • The TTR will only be specific for the reason of fault i.e. toss height.

Who will decide after reviewing the TTR?

  • The umpire requests the TTR with a signal, indicating a square with the hands.
  • The TTR crew replays the point in question in the TTR monitor room.
  • The final decision appears on the TTR playback screen.
  • The referees confirm or change the decision accordingly.

How many reviews that a player have?

  • 1 athlete / 1 pair of athletes may only appeal a maximum 2 times in a match
  • 1 appeal will be deducted if the contestant’s complaint is not successful.

Is TTR applied in all tournaments?

TTR technology will be applied in some selected tournaments.

A player may only request TTR for the referee’s decisions that directly affect him or her regarding the fault or score.

A player cannot request TTR in case an umpire has not called a fault service for the opponent.

A player cannot request TTR on a serve unless the umpire has already called a fault – so it can only be used to dispute when the umpire has already called a fault ? What a waste! The main problem of cheating in tabletennis is that umpires are never calling totally illegal hidden serves as foul. Let’s give the people receiving these serves a chance to help by giving them the option to challenge. Furthermore, I really think a player who in any match receives 3 TTR’d serves that show ball being hidden should result in immediate disqualification. I’m sick… Read more »
