Offside controversies have been constant in recent World Cups. Lines drawn over frozen images, decisions that depended on millimeters, and minutes of waiting while VAR reviewed each play. For the 2026 World Cup, FIFA promises that semi-automated offside technology will end most of these controversies.
How Does It Work?
The semi-automated offside system uses a combination of ball sensors and limb-tracking cameras to determine each player's exact position at the moment of the pass.
The official tournament ball contains a sensor that sends data 500 times per second. Simultaneously, 12 specialized cameras track 29 points on each player's body, creating a real-time 3D model.
Speed: The Big Improvement
In Qatar 2022, the system debuted with analysis times of approximately 70 seconds. For 2026, FIFA has managed to reduce this time to less than 25 seconds in most cases.
Visualization for Spectators
One of traditional VAR's biggest frustrations was the lack of clarity for spectators. The new system generates 3D animations showing exactly why a play is (or isn't) offside.
Is It Really Accurate?
The system has an error margin of approximately 10 centimeters. However, FIFA has established a "tolerance" protocol: if the difference is less than 10 cm, the system will give the benefit of the doubt to the attacker.
System Limitations
Semi-automated offside isn't perfect. In situations with overlapping players or physical contact, the system may struggle to determine exact positions.
Conclusion
Semi-automated offside represents one of the greatest technological advances in refereeing history. If it works as promised, the 2026 World Cup will be remembered as the tournament where offside controversies finally became a thing of the past.
