TLDR: multiple cameras do optical tracking on the ball for " millimeter precision ". The system is deployed because humans are fallible.

Transformed in the title is a real stretch.

Better title: ball tracking EyeHawk system replacing referees in tennis competitions.

Alternative title: “after 20 years Hawk eye is finally used at US open.”

I dunno. The match that prompted the change was pretty outrageous. Players shouldn't be competing against umpires as well as their opponent.

Exactly. The rule is "if the ball touches the line, it's out" (or is outside the line, whatever) why does it matter if a human judges it or a camera?

If it touches the line, it is in.

It matters because humans are fallible. Machines are much more reliable in situations where there is an unambiguous right answer. That match was awful to watch and it was made worse because the TV audience could see how badly the umpire was behaving.

I think my point came across wrong. I was angling for the "why shouldn't we use cameras since they're less fallible?", I don't understand when people say "we need human judges because that's more pure!" type responses.
