| [00:00.100] | From VOA Learning English, |
| [00:02.800] | this is the Technology Report. |
| [00:05.890] | Goal line technology made its debut |
| [00:09.530] | in international football |
| [00:11.420] | at the Confederations Cup in Brazil |
| [00:14.760] | that ended on sunday. |
| [00:17.100] | The move to goal line technology |
| [00:19.730] | follows international pressure |
| [00:22.680] | on the sport's governing body FIFA |
| [00:25.630] | after a missed call in the 2010 World Cup. |
| [00:30.550] | Video replays of a match clearly show |
| [00:34.430] | that England's Frank Lampard had scored a goal against Germany. |
| [00:40.070] | However, that goal was denied because neither the referee |
| [00:45.090] | nor linesman saw the ball cross the goal line. |
| [00:49.780] | The incident caused such a stir that FIFA |
| [00:54.770] | approve the development of goal line technology. |
| [00:58.600] | That technology was put to the test |
| [01:01.740] | at the Confederations Cup in Brazil which began June 15. |
| [01:07.870] | Bjorn Linder is the chairman of GoalControl, |
| [01:12.350] | the German-based company |
| [01:14.940] | that won the goal line technology contract |
| [01:17.980] | for this year's Confederations Cup. |
| [01:21.160] | His team spend weeks in Brazil before the games |
| [01:25.490] | as part of the FIFA certification process. |
| [01:29.340] | "The whole system uses 14 cameras |
| [01:31.820] | that are installed on the catwalk. |
| [01:33.520] | We have seven cameras per goal and computers |
| [01:36.210] | that are connected to those cameras. |
| [01:37.760] | The computers are catching the images, |
| [01:40.150] | around 500 pictures per second." |
| [01:43.410] | Computers track the path of the ball in real time |
| [01:47.690] | and reconstruct the play. |
| [01:51.180] | "Once the computer perceives the ball has crossed the goal line, |
| [01:54.270] | it gives a signal to the referee's watch, |
| [01:56.610] | so all the referees on the field receive the signal. |
| [01:59.090] | It vibrates and gives an optical signal 'goal' |
| [02:01.740] | and he knows a goal has occurred." |
| [02:03.680] | Electronic eyes on the goal line may settle arguments, |
| [02:07.810] | but the data is still only a reconstruction of reality. |
| [02:12.400] | Nic Fleming is a London-based science and technology writer, |
| [02:17.680] | he believes the use of goal line technology is a chance |
| [02:22.710] | to educate people about the role of uncertainty in science. |
| [02:27.560] | "These are fantastic tools, |
| [02:28.900] | but let's be realistic about their limitations, |
| [02:31.940] | that science is about probabilities. |
| [02:33.880] | What better way than to have this message in a game so popular." |
| [02:39.910] | GoalControl claims an accuracy of plus-or-minus 5 millimeters, |
| [02:46.140] | this is well under FIFA's minimum requirement of plus |
| [02:50.470] | or minus 3 centimeters. |
| [02:53.210] | Nic Fleming would like to see that number flashed on the screen. |
| [02:57.650] | He says viewers could compare the replays |
| [03:02.030] | to the computer reconstruction and learn a little science. |
| [03:07.300] | "The wider point really is that science is central |
| [03:10.500] | to many public debates today, |
| [03:12.100] | whether that's climate change or nuclear power or genetic modification. |
| [03:16.190] | In all of these cases science provides probabilities. |
| [03:21.170] | It does not provide yes-no, black-white answers |
| [03:24.910] | that is quite important to the public understands that." |
| [03:28.040] | Goal-line technology may become a central part of the sport, |
| [03:32.850] | but it is important to remember that is still the referee, |
| [03:38.180] | not the computer, that makes the final call. |
| [03:42.520] | And that's the Technology Report from VOA Learning English, |
