At the 2026 World Cup, FIFA has introduced a groundbreaking Semi-Automated Offside Technology (SAOT) system that slashes detection precision from 50 centimeters to just 10 centimeters. The system uses 29 tracking cameras, a sensor inside the match ball, and AI-generated 3D player avatars to create hyper-accurate models of every player, based on a one-second digital body scan taken before the tournament.
When an offside violation occurs, the referee receives an instant audio alert in their earpiece, eliminating the need for lengthy VAR reviews that interrupt the flow of the game. The AI handles the pure geometry of determining whether a player is ahead of the last defender, while human officials still adjudicate edge cases requiring interpretation and context.
This marks a significant shift in professional sports, as algorithms now manage one of the most consequential and debated calls in football. The technology aims to reduce errors and maintain the pace of the game, ensuring fairness without sacrificing the sport's momentum.
