Technology and football


The continuous evolution of technology has brought significant changes in many sectors. Among these we certainly find the world of sport, which thanks to the use of technology has been able to improve not only the performance of athletes but also collective and game performance. Let’s think, for example, of car or motorcycle sports, in which the engineering linked to the components of the various vehicles are of considerable importance: in this case, technology directly affects sports performance.

However, there is also an indirect influence and it is typical of football. This is certainly the most popular sport in Italy and technology has brought many innovations in this sector, making the role of referees in particular more simplified, minimizing the possibility of any errors during a match.

A first intervention of technology in this sport is certainly the increasingly frequent use of the online world: the various online sites are a typical example of bets.

Another factor of innovation is the use of very useful tools in the event that the referee’s eye cannot see and therefore clearly establish whether there is an offside, a penalty or a goal to be canceled. On the poles of the playing field there are cameras for remote observation and high resolution digital vision.

Another technology is the Hawk eye: it, of Japanese origin, is based on the triangulation mechanism in which 7 cameras for each door shoot at 200 frames per second. The images obtained are sent to a computer which scans them to identify the precise position of the ball.

The GoalRef is of German origin: thanks to the insertion of a sensor inside the air chamber of the ball and of devices that identify the changes in the magnetic field inserted on the goal posts, the referee is able to understand with a good degree of sensitivity whether the ball has crossed the line or not. Of the same purpose is the goal line technology, which unlike the use of the principles of magnetism, exploits the presence of seven cameras per goal that allow you to understand if there is a goal or not.

Finally, recently applied in various national and international competitions, there is the VAR, or slow motion in the field. It consists of a team made up of a series of referees who, located in a video room, have access to several cameras. Thanks to the latter, whose images can also be seen by the main referee at his request, they allow accurate decisions to be made.

The use of technology has certainly been of great help in this sector and we hope that it will be able to bring more and more spectacularity to a sport loved by many.
