Jakarta, INTI - The 2026 FIFA World Cup introduces a new generation of technology designed to enhance the accuracy and efficiency of match officiating. Among the tournament’s most significant innovations is the use of artificial intelligence (AI), which supports referees in making faster and more precise offside decisions.
Building on the Semi-Automated Offside Technology (SAOT) first introduced at the 2022 FIFA World Cup in Qatar, the upgraded system combines dozens of high-speed cameras, AI-powered data analysis, and personalized 3D player models to improve the accuracy of offside detection.
Throughout each match, multiple cameras positioned around the stadium continuously track the ball and every player's movements in real time. AI processes thousands of data points to determine the exact moment the ball is played and the relative positions of attacking and defending players. When a clear offside offense is detected, the system instantly sends an audio alert to the assistant referee through an earpiece, allowing officials to make decisions within milliseconds. This enables play to be stopped more efficiently, reduces unnecessary delays, and helps minimize the risk of injuries caused by prolonged offside situations.
3D Player Avatars and Human Oversight Improve Accuracy
A major enhancement for the 2026 tournament is the introduction of AI-generated 3D avatars for every player. Before the competition begins, each player undergoes a brief body scan during official team photo sessions. Lasting only about one second, the scan captures detailed physical measurements, including height, body shape, and limb proportions. These measurements are then used to create an individualized digital 3D model, replacing the generic player models used in previous tournaments.
The personalized avatars allow the AI system to track players with significantly greater precision, particularly in marginal offside situations where the difference may be only a few centimeters. The same technology will also be incorporated into broadcast replays, providing fans with clearer and more realistic visualizations of offside decisions.
Despite these technological advances, AI is not responsible for making the final decision. The system is primarily designed to identify clear offside incidents, particularly when a player is more than 10 centimeters beyond the last defender, and immediately notify the assistant referee. However, complex situations involving marginal offsides or multiple players still require review by the Video Assistant Referee (VAR). Match officials retain full authority to evaluate the footage and make the final judgment, while assistant referees may also disregard an AI recommendation if they believe further review is necessary.
By combining artificial intelligence with human oversight, the 2026 FIFA World Cup aims to deliver faster, fairer, and more accurate officiating while preserving the referee’s ultimate authority on the field.
Conclusion
The AI-assisted officiating system at the 2026 FIFA World Cup represents a major step forward in football technology, combining real-time data analysis, high-speed cameras, and personalized 3D player models to improve offside accuracy. While AI significantly accelerates decision-making, human referees and VAR remain responsible for the final judgment, ensuring technology enhances the game without replacing the authority of match officials.
