Computers and electronics have come to tennis. A computer-controlled line-call system will be used for?
Computers and electronics have come to tennis. A computer-controlled line-call system will be used for the first time in competitive tennis next Monday (26 September) when the Trophy Pernod indoor circuit tournament begins in Edinburgh, Scotland. The new system could eventually replace linesmen at tennis matches, particularly as plans are already well advanced to produce an even more sophisticated version to detect net cords and foot faults.
SYNOPSIS: Some of the world's greatest tennis players, such as Ilie Nastase, heave often won or lost crucial matches on a linesman's call. And, although they may protest about a line call, there has been no way of actually proving to the umpire whether a disputed "out" call - or the lack of such a call - was correct. Now, thanks to scientific research, the anguishing problems for players and linesmen alike could be over.
Four English international players put the new electronic line-call system to the test on Monday (19 September). The new system took seven years to develop.
The umpire sits in his usual position, but with a computer control-board to tell him whether a ball is in or out of court.
A new fabric on the tennis ball is electrically conductive. When a ball lands out of court, the umpire's control board emits a high-pitched sound and the "out" light comes on. The ball has completed the electrical circuits embodied in the area just outside the white line.
For tennis players, the new system eradicates linesmen's errors. But it also reports, unfailingly, every mistake by the players.
