Automated Line Calls Replace Human Judges at U.S. Open

With the coronavirus pandemic highlighting the need for safety, the upcoming U.S. Open tennis tournament will replace human line judges on 15 of 17 match courts with Hawk-Eye Live, an electronic system that makes automated line calls.

Transitioning from a quality control and broadcast tool in previous tournaments to a judge, Hawk-Eye Live features 18 cameras, six of which are used by a review official to monitor foot faults.

It uses recorded voices to make its calls, which shout “out,” “fault” or “foot fault.”

Courts using Hawk-Eye Live at the U.S. Open will have only a chair umpire to call the score after the system makes the call, and they will take over only if the system malfunctions.
