At the US Open, that voice yelling 'Out!' comes from a computer
The Peninsula
NEW YORK: Ash Barty, the No. 1 seed at the U.S. Open, watched on match point as her opponent's backhand sailed long on Thursday, prompting the familiar sound of a linesman yelling, "Out!"
There was no line judge, however. The call was a recording, triggered after an advanced system of cameras known as "Hawk-Eye Live" tracked the ball until it landed out of bounds. For the first time, the tennis major has installed electronic line-calling on every court, replacing human judges who were responsible for determining whether, say, a serve travelling at 140 mph touched a line the width of a ruler.More Related News
