Introduction to Connected Ball Technology
Connected ball technology has revolutionized the way decisions are made during World Cup matches. The use of advanced sensors in soccer balls played a pivotal role in the match between Portugal and Croatia, detecting a touch that was impossible to see with the naked eye or video replays. This technology led to the cancellation of Croatia’s late equalizer against Portugal, a contentious decision that left Croatian players and fans disappointed.
The Technology Behind the Decision
FIFA employs a soccer ball equipped with “advanced sensors” to ensure accurate decision-making during matches. The ball, used in Portugal’s 2-1 victory over Croatia, is known as the “Trionda” World Cup ball and is manufactured by Adidas. It contains a small inertial measurement unit (IMU) sensor which operates at a frequency of 500Hz, capturing data 500 times per second. This allows FIFA to monitor ball acceleration and movements in three dimensions, accurately detecting when a player makes contact.
The sensors provide an unprecedented level of data, enabling officials to make quick and precise decisions during crucial moments of a match.
Integration with Modern Technology
The ball’s data is synchronized with in-stadium cameras that transmit real-time tracking information to video assistants. This combination aids in determining offsides, handballs, penalties, and other critical decisions. Despite the inconclusive slow-motion replays from multiple angles, the connected ball technology identified the slight contact by Croatia’s Igor Mantanovic, putting Mario Palasic in an offside position.
Reliability and Accuracy
Professor Manos Tentzeris from Georgia Tech explains that the connected ball technology is highly reliable, with 99.99% accuracy in determining ball and player positions. This accuracy is crucial in determining offside positions, which can depend on minute details like the tip of a shoe.
Previous Use and Controversies
Connected ball technology was initially deployed at the 2022 World Cup and later at the men’s European Championship in 2024. Various tests from 2020 to 2022 demonstrated its effectiveness in different tournaments. Controversial calls, such as Denmark’s Joachim Andersen handling the ball in the box during Euro 2024, show its impact on match outcomes.
Critics like Denmark’s coach Kasper Hjulmand and Croatia coach Zlatko Dalić have expressed concerns that such technology may remove the emotional joy from football. Their views highlight the ongoing debate about balancing technology and the human aspect of sports.
Conclusion
While connected ball technology enhances decision-making accuracy, its influence on the sport’s enjoyment remains a topic of discussion among coaches and players.
