Artificial intelligence is penetrating all spheres. Sports is no exception. In refereeing, AI already helps determine offside, simulations, even roughness. In 2026, at the World Cup, AI-assistants will be used for the first time. We tell you how it works, what it gives, and whether AI can fully replace a human. How AI helps the referee System of semi-automatic offside: cameras track 29 points on the player's body. AI calculates the moment of the pass and the position of players in fractions of a second. The result on the referee's screen. Determination of simulation: analysis of player movements (how fast does he fall, does it coincide with contact). AI was trained on thousands of examples. Prediction: the neural network predicts where the ball will go and suggests possible positions of players. Violations: AI detects a hit without the ball, play with the hand, even rough verbal abuse (analysis of the lips). Important: AI only recommends, the decision is up to a human. Advantages of AI in refereeing Objectivity: no emotions, does not cheer for teams. Speed: offside is determined in 5 seconds (before 90). Accuracy: in controversial moments, an error of 1 cm. Predictability: treats similar episodes the same way. Assistance to the referee in difficult decisions (such as expulsion). Thanks to AI, the number of gross mistakes at the 2026 World Cup may be reduced to 0. Disadvantages and limitations AI does not understand context (for example, was it intentional). Cannot determine "the force of the hit" (foul or not?). Does not take into account psychology (heat of passion). Failures: if the camera loses the player (due to obstruction). Ethics: players will argue not with the referee, but with a robot. Disputes about millimeters: offside in 1 cm, which does not give an advantage, is still recorded. AI kills emotions (you can't argue with a machine). Complete replacement of a human is a utopia. Future In 2026-2030, AI will start to be used to assess the severity of fouls ... Read more
