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.
  
  What match was it?
  
  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?
Sony bought it from a UK developer called Paul Hawkins

- You think he calls his house the "Hawk-Nest"?
i was wondering what Tony Hawk has to do with tennis. had to read the comments to figure it out.
So true. The game is completely unrecognisable now, basically a different sport. There was tennis before Hawk-Eye, and tennis after Hawk-Eye. Soon, the old tennis will be just a distant memory for those of us who were around when the switch happened, telling stories to our children, remembering the days before the Hawk-Eye system and chuckling to ourselves when they ask us what a line judge was. Tennis hasn't just been transformed, no, it has evolved, it's previous form no more recognisable or relevant to the current game than the first arthropods are to us.
