Version 3.0 is 200% more powerful with the "IO 3" chip inside both the Net and Line Devices. IO3 is the first ever-designed chip that natively detects balls and lines. The benefits of a chip is performance, accuracy, battery life, and cost.
In 2020, in response to the need to reduced the number of people on the court, the U.S. Open tennis tournament replaced human line judges on 15 of 17 match courts with Hawk-Eye Live, an advanced system that makes automated line calls in real time. This Hawk-Eye Live system features 18 cameras, six of which are used by a review official to monitor foot faults.

An electronic line judge is a device used in tennis to automatically detect where a ball has landed on the court. Attempts to revolutionize tennis officiating and the judging of calls in the sport began in the early 1970s and has resulted in the design, development and prototyping of several computerized, electronic line-judge devices.
In 2018, they replaced all human line umpires with a new version of Hawk-Eye that makes live calls. The chair umpire is still responsible for running the game. But the computer system makes all calls at the lines. “In tennis, it’s a very thin line between in and out [of bounds],” says Townsend.
One of those line judges ended up in the line of fire when a frustrated Djokovic blindly smacked a ball toward the back of the court. When it hit her in the neck and she fell to the ground, the ...
Sloane Stephens of the Smash hit her first serve in play. Coco Vandeweghe of the Empire took a bold forehand cut and her return flew well out of Stephens’ reach, landing deep near the baseline. There was no call by a line judge, because there were no line judges on the court. Instead, the critical call was made electronically, and though Stephens and the Smash asked to see a replay of the virtual ball mark, it only confirmed the judgment of the machine.
After capturing the ball’s movement, the system sends it to a machine that produces a 3D video representation of the ball’s path. The technology makes it easier to identify foot faults and line calls. Given Hawk-Eye’s recent success, many tennis pundits believe the technology might replace line judges. This would change a lot in the sports world.
World TeamTennis was using Hawk-Eye Live, an automated system that not only eliminates line judges but also eliminates the now-familiar challenge setup in which players can ask for human calls to...
