How is the ball touch 'speedometer' at Euro 2024 designed?

"Connected ball" technology designed with a motion sensor microchip with the ability to track every touch at a speed of 500 times per second was first put into use at Euro 2024 - the 2024 European Football Championship. takes place June 14 - July 14.

"Connected ball" technology is similar to the snickometer technology that has long been applied in cricket, and is applied at Euro, helping to identify cases of handball and offside.

The competition balls are equipped with a motion sensor microchip capable of tracking every touch at a speed of 500 times per second. This helps determine whether a player was standing below the opponent's last defender at the time the ball was kicked or whether the ball touched anyone's hands on the way to the goal.

This high-tech ball is produced by a collaboration between Kinexon, a company headquartered in Munich, Germany, the International Football Federation (FIFA) and Adidas. In 5 years, 1,500 high-tech balls have been produced for the 2022 Men's World Cup and 1,500 for the 2023 Women's World Cup. The same thing was done by Kinexon with the match balls in Euro 2024 for men and Euro 2025 for for girl.

Daniel Linke, product marketing and strategy lead at Kinexon, said that due to camera shutter speed, motion blur, image angle and resolution, using only an image-based system would be more likely. greater possibility of error. Kinexon's in-ball chip can judge when the ball is touched at 500 times per second, while standard broadcast cameras (used by VAR) record at 50 frames per second.

Connected ball technology, allowing you to accurately determine the moment of contact with the ball instantly. Within just a millisecond or two, Nn is in perfect sync with the video signal. Every time there is a touch signal sent from the ball chip, the camera system's algorithms continuously work to evaluate the offside situation.

At the 2022 World Cup taking place in Qatar, this Microchip helped the VAR team make decisions in real time.

Now, when these images are used to make key decisions during a match at Euro 2024, they will be made available to viewers via giant screens inside stadiums and on television to enhance their relevance. transparency in the European Football Union (UEFA).
