It is the Clay Court season in tennis, and instead of questioning the rulings of the chair’s referees, some players are now wondering about the complex software decisions-and specifically the line call systems (ELS), which are increasingly assigned to determine whether the ball is present or outside.
German tennis star Alexander Zverev He became the latest technology after describing his opponent’s ball “in” during the Madrid match open against Alejandro Davidovich Fukyina, as I mentioned Earlier Athlete. Zverev pointed to the contradiction between the ELS call and the ball brand, which appeared outside the court of the court.
While in solid and herbal stadiums, other surface tennis players compete, as a unique kidneys because they consist of loose molecules of bricks and stone. This also means that when the ball strikes a stadium of clay, it leaves a sign of the place she wore. This is often used as a clear and indisputable evidence for whether the ball is inside or outside. So what happens when the automatic naming program differs with the visual mark left by a clay ball?
“The device does not work,” Zvevv said To the Chair of Governance. “Look at this mark … Please go down.” He withdrew his phone to take a picture of the brand and post it on Instagram, which led to a warning to Non -athletic behavior. Other players took pictures of the disputed shots during the tournament as well, including Victoria Azzinka and Eva Liz.
Although ELS is generally popular with players, we will likely see more conflicts this year, with the ATP Association continues to continue Replace human calligraphy judges With ELS via major championships (with the French Open Championship, Sole Clay Grand Slam, being the only exception).
Hawk-Eye, one of the companies behind this technology, uses a group of cameras to predict the place headed by the ball by analyzing its speed, rotating and skiing with three millimeters. “The system assumes the place where the ball will wear before its arrival, and it is a prophecy in the future with the confidence of the common power of physics, monitoring technology, and a trained algorithm on billions of data points,” Kevin Ngwin writes in a deep diving on the system.
Hawk Announced last year The direct communication system is ready for clay courts, as lines and referees have used physical balls for a long time to make calls. But the appearance of the football mark may change based on whether the clay is wet or dry, as well as if there is more or less mud in the court, as is detailed in this video From ATP tour. Some of these signs can be a deception of the human eye.
“The clay is a completely different surface – the most difficult surface is to work on” He said in an interview last year. “Interpretation of the mark is a personal matter, and reading the mark is very complicated. This will be clear, by Els Live.” How does the player interact with the system’s decision only will add to Clay Drama Court.
