Semi-automated offside technology (SAOT) will be implemented in the FIFA World Cup 2022 in Qatar beginning on November 21, providing a support tool for video match officials and on-field officials to enable them to make faster, more accurate, and consistent offside judgments on the worlds stage.
Following the successful use of VAR technology at the 2018 FIFA World Cup in Russia, FIFA President Gianni Infantino declared in ‘The Vision 2020-23’ that FIFA would “strive to harness the full potential of technology in football and further enhance VAR”. In the ensuing three years, FIFA said, it has continued to be at the cutting edge of technology in the game.
“By working with adidas and various partners, and especially with the Working Group for Innovation Excellence and technology providers, FIFA has spent the last few years further improving the VAR system, including the use of semi-automated offside technology,” FIFA said.
What is semi-automated offside technology
The new system employs 12 specialized tracking cameras positioned beneath the stadium's roof to track the ball and up to 29 data points of each individual player 50 times per second, estimating their precise position on the field. The 29 data points obtained cover all limbs and extremities that are crucial for making offside calls.
The Al Rihla, adidas' official match ball for Qatar 2022, will include an inertial measuring unit (IMU) sensor, which will aid in the identification of close offside events. This sensor, located in the center of the ball, transmits ball data to the video operating room 500 times per second, allowing for extremely accurate identification of the kick spot.
The new technology, which combines limb- and ball-tracking data and employs artificial intelligence, sends an automated offside alert to video match officials inside the video operation room whenever the ball is received by an attacker who was in an offside position at the time the ball was played by a teammate.
Before contacting the on-field referee, the video match officials personally review the automatically determined kick point and the automatically constructed offside line, which are based on the computed locations of the players' limbs. This procedure takes only a few seconds, allowing offside judgments to be made more quickly and correctly.

After the decision is validated by the video match officials and the referee on the field, the exact same positional data points used to make the judgment are created into a 3D animation that accurately specifies the location of the players' limbs at the instant the ball was played.
This 3D animation, which will always depict the greatest potential viewpoints for an offside scenario, will subsequently be projected on the stadium's enormous screens and made available to FIFA's broadcast partners in order to notify all fans as clearly as possible.
The semi-automated offside technology workflow and linked ball technology have been successfully trialed at various test events and live at FIFA competitions, including the FIFA Arab Cup 2021 and the FIFA Club World Cup 2021.
During these matches, the new technology was able to assist video match officials by assisting them in making more precise and repeatable offside rulings in less time.
