How is Technology in Football Used
Technology is slowly beginning to show rapid growth in various fields, which includes its use in sports as well. Touch sports such as soccer and football is fast making use of some form of technology or the other to make the gaming experience a little better and pleasant.
From this article, you will come to know about the usage of technology in football.
Why is the technology of Soccer Goal Line used?
Goal Line Technology in football is currently the need of the hour. The reason behind this is, often we have seen that television replays have shown how a wrong decision has been given by the referee, wherein a ball may have or may not have gone over the goal line based on which the goal may or may not have been given.
However, there are several other requirements of the Goal Line Technology which will be discussed further.
The below-mentioned criteria is usually necessary for a proper goal line-system:
- It is necessary to ensure the accuracy of the system is always 100%
- An instantaneous signal to the referee should always be sent.
- The signal should always be communicated with the match officials.
What are some of the several options considered for goal-line technology?
There were mainly three distinct options which were considered with regards to the soccer goal-line technology.
Back in 2013, FIFA had granted a licence for the technology manufacturer of third goal-line – a German firm by the name of Cairos which was to join the GoalRef and Hawk-Eye systems for their rights to use in 2014 World Cup as well as the 2013 Confederation Cup, both of which were to take place in Brazil.
What is the Smart Ball System?
The Smart Ball System is an up-and-coming prospect which has a ‘smart ball’, comes with a sensor that is suspended inside and it was jointly developed by the German companies – Adidas and Cairos Technologies.
The companies made use of a technology whereby the receivers near the field were designed to track the ball’s exact location in real-time. This includes the precise detail of when it had fully managed to pass the goal line. This information is relayed to the referee within a fraction of second.
What is the Hawk-Eye System?
The Hawk Eye System was by a UK company of the same name. Because of their several successful trials, they are considered as the front runner of all the systems that are currently in development.
The football version is repeatedly tested, and it has done well through all its trials. This system makes use of three cameras which are focussed on the goal-lines and each of which takes 600 footages in a second.
It can give a decision if the ball has wholly crossed the line and then simultaneously relays the same information in an audio beep within half of a second to the central referee.
Since the Premier League referee makes use of headsets, the signal can quickly be sent. In other leagues, this signal can be sent through a watch.
What is the Goal Ref System?
The Goal Ref is a detection system that was developed by a company called Fraunhofer IIS. It is based on a radio system that uses magnetic fields of low-frequency in order to determine the direction of the ball on the goal line.
Two magnetic fields that are used:
- In goal area (by the use of coil attachment to the goal)
- Around the ball (with the help of a passive electronic circuit which is embedded on the ball).
Data is processed and then wirelessly transmitted to the watch of the referee, whereby in real-time a message is displayed along with a vibrating alert.
What is the VAR?
The VAR or Video Assistant Referee is a technology in football that was made use of in the 2018 FIFA World Cup held in Russia, to assist with the referee’s decisions.
It had successive trials over a few years. A total of four different calls can be reviewed – decisions related to penalties, red card decisions, goals and any form of mistaken identification in giving a card.
With the help of the video assistant referee, the video of the event is replayed and when a clear error is observed it can quickly relay the information of that to central referee with the help of a wireless radio to the referee’s headset.
VAR was included in the laws of the game of football by official lawmakers from the International Football Association Board (IFAB) in 2018.
When was the beginning of technology in football?
Long before, a camera system – similar to the Hawk-Eye was considered the best. FIFA in 2013 announced that cameras should monitor the Goal Control.
This should be made use of in the Confederation Cup, 2013. Not only was the trial run successful but also the use of the Goal Control system was confirmed to be used in the FIFA World Cup held in 2014.
Goal Control used 14 cameras of high speed that were located all around the pitch. The cameras were directed towards both the goalposts. The English Football Association (EFA) announced in 2013 that they would make use of the Hawk-Eye for the 2013-2014 Premier League Season.
What is Foam Technology?
Recent technology in football is spraying of vanishing foam that gained prominence in the 2014 FIFA U-20 World Cup. It is implemented by the referee onto the field to help provide a visual marker that can be used by both players as well as referees.
This helps by indicating the minimum distance which the opposing teams have to maintain from the ball while the free kick is taken.
Technology in football is still developing and will most likely won’t stop doing that for a long time.
