From the Hawk-Eye to the Goal-Line to the Video-Assistant Referee to the Electronic Performance and Tracking Systems, football has embraced technology.
It’s no secret that football, like many other sports, has benefited from the constant stream of technological innovations.
However, there are many different football leagues and continental cups, and some of them don’t use certain types of technology because of fan preference or association rules.
Although the odds of this technology being useful are low, nine times out of ten it has helped match officials make the correct call. Though perhaps not the most well-liked.
Fans of the beautiful and mesmerizing game of football (or soccer) can be found in every corner of the globe. Even though it was a few years ago, we all remember how impressive the technology used at the 2018 FIFA World Cup was.

For the past few years, the new video assistant referee (VAR) in football has been among the most loved and hated of the new technology in the sport, proving once again that technology can create controversy and contention in a sport already loaded with passionate fans.
“Technology at these international or intercontinental sporting events has the potential to showcase new ideas and innovations that would otherwise go unnoticed in smaller, more localized leagues. The stakes at global events are high, and so are their budgets “SuiteHop’s SVP of Operations Mike Guiffre put it this way.
In this article, we’ll take a close look at the evolution of 좋은느낌 카지노 football technology, from the ball itself to Hawk-Eye, and from Goal Line Tech to Video Assistant Referees.
The History of the Football and Its Name:
The Chinese were probably the first to use and create the first ball, around 250 BC. The Chinese would inflate an animal bladder and then cover the ball in leather to give it more durability and consistency.
The first ball with a rubber bladder was created by Goodyear.
Before the invention of vulcanized rubber, which Charles Goodyear patented in 1833, people had to rely on the size and shape of the animal’s bladder to determine the quality of their balls. Goodyear went on to create the first rubber-balled football in the United States in 1855. The rubber bladder ensured that ball dimensions and shapes were consistent, making for a more level playing field.
While football’s fundamentals are simple, the sport has seen significant technological advancements over the past century. As we’ve seen, the first balls were created by inflating a pig’s bladder before covering it in leather; this basic design is still in use today, minus the pig.
The standard modern ball is an air-filled rubber sphere covered in a variety of materials chosen by the manufacturer. Football is played by kicking a ball; today’s inflated balls are safer for players to kick hard without risking injury because they are softer, lighter, and more durable than their predecessors.
Both Adidas and Nike are huge in the football industry. The Nike Flight, which replaced the Nike Merlin in use since the 2020/21 season, is the official Premier League ball that Nike currently supplies.
Electronic Game Balls:
German companies Cairos Technologies and Adidas collaborated to create a “smart ball” embedded with a sensor (NFC chip), which has shown promising results.
The technology employs a system of receivers strategically placed around the field to monitor the ball’s location in real time. This allows for pinpoint determination of when the ball crosses the goal line. The referee’s smartwatch will act as a receiver for this information, letting them know when the ball has crossed the goal line.
European leagues, Major League Soccer, and other American leagues all use the same official match balls. The majority of African Leagues use intelligent balls. Smart ball footballs include the Brazuca (2014 FWC ball), Telstar (2018 FWC ball), Uniforia (Euros 2020 ball), and Nike Strike (Copa America 2020 ball).
GLT (Goal-Line Tech):
The referee’s job is greatly aided by his or her ability to distinguish between a goal and a near miss.
A key component of the technology used at the 2018 FIFA World Cup in Russia was Goal-Line Technology, which had its debut at the 2014 World Cup in Brazil.
Up to 500 frames per second are captured by 14 cameras and sent to an image processing system as part of Goal-Line Technology (GLT). When the ball completely crosses the goal line, the camera will have captured it in 3D and sent a signal to the referee’s watch.
As it did in Brazil, GoalControl continues to supply the technology at major international football tournaments.
The following guidelines should be considered when designing a goal-line system:
Only decisions at the goal line should be affected by the technology.
- The system must be foolproof in every way.
- The referee must receive the signal immediately.
- Only the game officials will be able to see the signal.
- Tech for Smart Balls
Referencing the Aim:
Fraunhofer IIS has developed a system called Goal Ref for detecting goals.
This system uses radio waves and magnetic fields with a low frequency to determine if the ball has crossed the goal line in its entirety. One magnetic field is generated by coils attached to the goal, and the other is generated by a passive electronic circuit inside the ball and the area around it.
The information is then sent to the referee’s wristwatch, where it is processed and displayed alongside a vibrating alert, all in real time.
A Hawk’s Eye View:
In 2001, UK firm Hawk-Eye Innovations Ltd introduced the system, and since then, it has undergone numerous successful trials. When compared to other systems in development, it is far and away the winner.
The use of Hawk-Eye in sports like tennis and cricket is nothing new. The Football variant has been thoroughly tested, and it has fared well in simulations.
Three cameras, one at each end zone, capture footage at 600 frames per second for the Hawk-Eye system. Within half a second, Hawk-Eye can determine with absolute certainty if the ball has completely crossed the line and communicate this information to the central referee via an audible beep. Since the officials in the Premier League all wear headsets, relaying the signal to them is simple. The signal can be received in a variety of ways in other leagues, including through a watch.
The Video Review Official (VAR):
At the 2018 FIFA World Cup in Russia, a novel type of video technology known as the Video Assistant Referee was used to aid in officiating.
The goal was to find mistakes that had been overlooked earlier. The VAR staff provides assistance to the match officials via a centralized video operations room located in the stadium’s international broadcast center.
They have access to all 33 camera feeds from around the stadium, plus two additional offside cameras, and are comprised of one video assistant referee, three assistants, and four replay operators. CNET claims that two cameras are trained on the referees, making their decisions transparent to the public.
The technology is deployed only when a call has the potential to alter the outcome of a game. The VAR team communicates with the on-field officials and can call a timeout at any point if a “clear and obvious error” has been made.
Systems for Monitoring and Evaluating Performance Digitally (EPTS):
Electronic Performance and Tracking Systems (EPTS) are used to manage and enhance player and team performance. EPTS include camera-based and wearable technologies. Microelectronic devices (such as accelerometers and gyroscopes) and heart-rate monitors, as well as other devices to measure load or physiological parameters, can be used in conjunction with EPTS to track player and ball positions.
Micro Electrical Mechanical devices (like accelerometers, gyroscopes, and compasses) are used in tandem with these to provide inertial load and other medical data. There are three EPTS units for each squad. One is for a sideline reporter, another is for a bench reporter, and the third is for the medical staff. Cameras with optical tracking technology keep an eye on the field and relay information about the players and the ball. It is compatible with wearable and camera-based systems.
There are currently three distinct types of physical tracking devices on the market:
- Cameras that rely on optics
- GPS receivers for use on the ground (LPS)
- Navigational satellite systems (GPS/GNSS)
In conclusion, football’s use of technology:
Where do you see football technology going from here? From holographic pitch additions to multi-sensory headsets for viewers and computer referee officials, the potential applications of virtual and augmented reality have been the subject of much discussion.
The rapid development of new technologies means that soon they will be tested in an effort to better the most popular sport in the world. There will be challenges in implementing something on this scale, as well as opposition and setbacks. Football players, teams, commentators, and fans still have a lot to look forward to in the next decade.
