A GoalControl watch reads "goal" as a football rolls fully behind the goal line during a demonstration in the western German city of Aachen May 28, 2014. German firm GoalControl has been appointed by FIFA as the official provider for the goal-line technology (GLT) at the upcoming 2014 soccer World Cup in Brazil. GoalControl uses 14 high-speed cameras around the pitch as part of its GoalControl-4D system, which are fixed in elevated positions around each goalmouth. The ball's position is continuously captured in three dimensions - X, Y and Z coordinates. All the cameras are linked to a computer processing system, which filters out players, the referee and any other objects. Only the ball remains, with its position precise to a few millimetres in the coordinate system of the pitch, according to the GoalControl website. The watch will be worn by referees and will display the word "goal" together with a vibration alert within one second, if the ball has fully crossed the goal line. REUTERS/Wolfgang Rattay
