- Battery: A rechargeable battery to power the sensor.
- Data Transmission Technology: Technology to transmit data to video match officials.
This technology helps officials make faster and more accurate decisions, particularly in offside situations and unclear touches.
2. The Evolution of Football Technology: From Simple Leather to Smart Sensors
The evolution of football technology has been remarkable. Early footballs were simple, hand-stitched leather casings filled with inflated animal bladders. These were inconsistent in shape and weight, and their performance varied greatly depending on weather conditions.
2.1. Key Milestones in Football Development
| Year | Development | Impact |
|---|---|---|
| 1855 | Charles Goodyear designs and makes the first rubber soccer balls | Uniform bounce and increased durability. |
| 1950s | Synthetic materials introduced | More consistent shape and water resistance. |
| 1986 | First fully synthetic World Cup ball (Azteca) | Improved performance in wet conditions. |
| 2006 | Teamgeist ball with fewer panels (14 instead of 32) | Rounder and more consistent performance. |
| 2022 | Connected ball technology introduced | Real-time data for VAR, enhancing officiating accuracy. |
2.2. The Shift to Data-Driven Officiating
The introduction of connected ball technology marks a significant shift towards data-driven officiating. By providing precise, real-time data, these advancements aim to eliminate human error and ensure fair play.
3. Understanding Connected Ball Technology: How Does It Work?
Connected ball technology works through a combination of sensors, data transmission, and artificial intelligence. This system captures and transmits data about the ball’s movement to video match officials in real time.
3.1. The Inertial Measurement Unit (IMU)
At the heart of the connected ball technology is the Inertial Measurement Unit (IMU). This motion sensor tracks every touch of the game at a rate of 500 times per second.
- Function: Measures the ball’s acceleration and angular velocity.
- Frequency: Operates at 500Hz, providing highly accurate data.
- Location: Housed in a suspension system in the center of the ball to ensure stability.
3.2. Data Transmission and Processing
The data collected by the IMU is transmitted to video match officials in seconds. This information is then combined with player position data and processed using artificial intelligence to inform decisions about offside situations and unclear touches.
3.3. Powering the Technology: The Rechargeable Battery
The sensor is powered by a rechargeable battery, which can be charged by induction. This ensures that the technology can operate throughout the match without interruption.
4. The Benefits of Connected Ball Technology: Enhancing Accuracy and Fairness
The primary benefit of connected ball technology is the enhancement of accuracy and fairness in officiating. This technology provides real-time data that helps officials make faster and more accurate decisions.
4.1. Improving Offside Decisions
Connected ball technology is particularly useful in offside situations. The precise data about when a player touched the ball, combined with player position data, allows video assistant referees (VAR) to make more informed decisions.
4.2. Detecting Unclear Touches
The technology also assists in detecting unclear touches, which can be crucial in determining fouls, penalties, and other game-changing events.
4.3. Speeding Up VAR Decisions
By providing instantaneous information, connected ball technology speeds up the VAR decision-making process. This reduces delays and keeps the game flowing more smoothly.
5. The Al Rihla: A Case Study in Connected Ball Technology
Al Rihla, the Official Match Ball of the FIFA World Cup™ 2022, was the first World Cup ball to feature connected ball technology. This ball provided precise data to video match officials in real time, contributing to FIFA’s semi-automated offside technology.
