BWF brings hawk eye challenge system to 2014 Badminton China Open in Fuzhou and marks its debut on Chinese courts.

Dutch female shuttler Eefje Muskens and her partner Selena Piek made the first challenge during the women' s Doubles game against Chinese opponents Chen Qingchen and Jia Yifan.

In the second set, Dutch players doubted if the smash ball is in the sideline and challenge the umpire when the score goes to 7-6. The hawk eye system proved the umpire is correct and the challenge failed. Finally, the Dutch pair beats their Chinese counterparts, 21-15, 21-17.

Ronny De Vos, chief referee from Belguim told Xinhua the hawk eye challenge system in badminton court has 8 cameras and 4 computers. BWF authorizes a British company to provide the service.

"Hawk eye was initially applied in 2013 BWF Destination Kuala Lumpur Super-Series Finals," said Ronny, "This technology now has been popularly used in BWF' s big events like super-series and Championships to ensure the just and justice."

Daniel Nicholas, one of the British technical group, told Xinhua he made many tests, especially on focus, with his colleagues before the game began. Under Daniel' s desks, there are 3 boards saying respectively "IN" , "OUT" and "No Decision" .

When the challenge is required, the big screen up in the stadium did not show the 3-D review. Daniel told the technical judge the result proved by Hawk eye and the judge raised the board to inform the referee on court.

"The computer screen looks a bit flickering perhaps the lights' frequency may not fit well." said Daniel, "But we' re OK with that. It won' t affect."

According to the rules, players are supposed to challenge twice per game. They will keep the right if succeeds, and maintain once if failed.

Due to the expensive cost, only one out of 5 courts is set up with the system which will offer the images to TV broadcasting as well.

Hawk-Eye is a complex computer system used officially in sports such as cricket, tennis and football, to visually track the trajectory of the ball and display a record of its statistically most likely path as a moving image.

The technology is used for the Challenge System since 2006 in tennis and Umpire Decision Review System in cricket since 2009. The system was rolled out for the 2013-14 Premier League season as a means of goal-line technology.
