Semi-automatic Offside Technology in 2022 World Cup, How Does It Work?

Qatar welcomes 2022 World Cup

The 2022 World Cup will bring many new innovations. FIFA, as the highest authority in world football, has just signed a new rule that will be implemented at the 2022 World Cup in Qatar, namely semi-automatic offside.

There is something new at the 2022 World Cup in Qatar. After implementing VAR technology at the 2018 World Cup in Russia, FIFA will now use semi-automatic offside technology at the biggest balbalan party which is scheduled to start on November 21.

FIFA has been doing research for years before finally announcing its new discovery. In order to pass the idea, FIFA has discussed and cooperated with its partners.

This new technology uses 12 special tracking cameras mounted under the stadium roof to track the ball and up to 29 data points from each player, 50 times per second, calculating their exact position on the pitch. Twenty-nine data points collected cover all limbs and extremities relevant to offside calls.

In addition, Al Rihla, the official Adidas match ball will also provide a further important element for detecting offside incidents. This is quite tight, because the sensor of the inertial measurement unit (IMU) will be placed inside the ball.

The sensor is positioned in the center of the ball, transmitting data to the video operating room 50 times per second, enabling very precise detection of kick points.

Using leg and ball tracking data and applying artificial intelligence, this new technology provides automatic offside alerts to match officials. Before notifying the referee on the pitch, the video match official validates the proposed decision by checking manually.

This process occurs within seconds and offside decisions can be made faster and more accurately. Once a decision is confirmed, the exact positional data points used to make the decision are then rendered into a 3D animation that perfectly details the position of the player’s limbs on the field.

When the ball is in play, the 3D animation will always show the best perspective for the offside situation and is then shown on the giant screen in the stadium. Spectators far away from home can also see clearly.

Previously, FIFA had conducted trials on various occasions such as the 2021 Arab Cup and the 2021 edition of the Club World Cup. Thanks to this advanced technology, match officials can help make more accurate offside decisions.

All the details regarding the semi-automatic offside technology setup and the connected ball technology have been presented to the teams that qualify for the 2022 FIFA World Cup in Doha on 4 and 5 July.

President’s Explanation

FIFA President Gianni Infantino

“At the 2018 FIFA World Cup, FIFA took the bold step of using VAR technology on the world’s biggest stage and it has proven to be a success,” said Gianni Infantino, FIFA President.

“The semi-automated offside technology is an evolution of the VAR system that has been implemented around the world. This technology is the culmination of three years of dedicated research and testing to provide the best for the teams, players and fans heading to Qatar later this year,” he added. Infantino.

Pierluigi Collina, chairman of the FIFA Referee Committee, said the same thing. “VAR has had a very positive impact on football and we can see the number of major errors have reduced dramatically,” he said.

Collina hopes that his party can go further than before. “We hope that the semi-automatic offside technology can take us one step further. We realize that sometimes the process of checking for possible offsides takes too long, and this technology is the solution,” explained Collina.
