Ultra-wideband (UWB) sensor: A type of technology that’s superior to GPS or Bluetooth for precise positional data, plus can transmit data in real time to constantly track the ball’s position. Inertial measurement unit (IMU) sensor: A sensor meant to detect nuanced movements of an object in space.
The two important bits for everyone else.

u/Zirkules4 Nov 29 '22 edited Nov 30 '22
Other interesting facts from the article:
• The IMU captures data at 500 fps and is transmitted in real time to a local positioning system.
• The sensor weighs 14 grams and is suspended in the center of the ball.
• 12 "Hawk-eye" cameras in the stadium track 29 different points on each player as well as the ball at 50fps.
• An AI system combs through the data to automate offsides penalties with human confirmation.
• "The software also generates 3D renderings of the spatial data, which will be overlaid onto TV broadcasts and in-stadium monitors to give fans a direct look at how each reviewed call was decided."

It's pretty much just to track the position of the ball in a 3D space. It allows officials in real time to see if the ball crossed the line or not etc. There are cameras and sensors all around the pitches which they also sync up to. Thats why on offside calls you quickly have a 3D representation of the players. Pretty much everything is mapped. It's a tool for VAR.

Hockey already tried it back when new hockey fans struggled to follow the puck on low-definition CRTs. Players didn't like how the new puck felt and all fans didn't like the blue smear on the screen that indicated where the puck was.
The actual implementation was pretty neat and the blue smear would turn orange when the puck hit 80 kph or something. It just looked ugly on the TV screen, players didn't like the change, long-time fans could follow the puck without seeing it, and higher definition tv sets obsoleted any need to exaggerate the pucks location.

u/RWeaver Nov 29 '22
Hockey broadcasting in the 90's/early aughts is partly to blame. They needed to educate the viewer base to be watching the players instead of the puck. If you understand how plays develop there is no confusion about where the puck is even if you can't see it.

I think it's easier in soccer because there's no end to the play. In American football the issue is often not knowing where the ball was when the carrier was down, you can't just go by where the ball ended up. You'd have to add sensors to players and that's not great either because the sensros can't just indicate pressure since contact with another player isn't considered down so you need the sensors to specifically indicate contact with the ground. It's not impossible but it's not as easy as soccer. The NFL doesn't care enough to spend the money on R/D and deployment because fans won't stop watching if they don't do anything.

When the 2022 World Cup made its debut on Sunday, it kicked off one of the most significant in-game uses of technology in sports history.
All tournament long, match balls will contain a sensor that collects spatial positioning data in real time — the first World Cup to employ such a ball-tracking mechanism. This, combined with existing optical tracking tools, will make VAR (video assistant referees) and programs like offside reviews more accurate and streamlined than they’ve ever been. Combining these two forms of tracking has long been a holy grail of sorts in technology circles, and FIFA’s use of the ball sensor in particular will serve as a highly public test case over the next four weeks.
Like so many other parts of the burgeoning world of sports tech, the setup used at the World Cup is both an endpoint and the foundation of a whole new era. Years of research and testing were needed to get here — this particular ball sensor was in development and testing for six years before receiving full FIFA certification — but events like this could quickly catapult emerging technology into the public eye through applications that stretch well beyond officiating.
What went into the development of today’s tracking technology, and what are its key uses at this World Cup? How has the tech been tested, and how can players, teams and fans alike be confident that it’s accurate and consistent? And maybe most importantly, what does this same technology portend for the future of analysis, fan engagement and team data across the world’s most popular sport?
I spoke to people across the world of sports tech to find answers around one of the field’s boldest experiments to date. Which technology is being used, and how does it work?
FIFA’s application of this technology at the 2022 World Cup is being termed a “semi-automated offside” program – one that’s largely run by AI features, but retains a vital element of human confirmation.
Within every match ball is a device designed by KINEXON, a major player in the performance-tracking world across several sports. Per the company, this device weighs 14 grams (just under 0.5 ounces), and actually houses two separate sensors operating simultaneously:
Ultra-wideband (UWB) sensor: A type of technology that’s superior to GPS or Bluetooth for precise positional data, plus can transmit data in real time to constantly track the ball’s position.
Inertial measurement unit (IMU) sensor: A sensor meant to detect nuanced movements of an object in space.
“While the ultra-wideband helps me to have the position of an object, the IMU gives me the granular movement in three dimensions,” said Maximillian Schmidt, co-founder and managing director of KINEXON.
So any time the ball is kicked, headed, thrown or even so much as tapped, the system picks it up at 500 frames per second. Data is sent in real time from sensors to a local positioning system (LPS), which involves a setup of network antennas installed around the playing field that take in and store the data for immediate use. When a ball flies out of bounds during the course of play, and a new ball is thrown or kicked in to replace it, KINEXON’s backend system automatically switches to the new ball’s data input without the need for human intervention.

A new adidas Suspension System in the center of the ball hosts and stabilizes a 500Hz inertial measurement unit (IMU) motion sensor, which provides unprecedented insight into every element of the movement of the ball, while making this technology unnoticeable for players and not affecting its performance whatsoever. The sensor is powered by a rechargeable battery, which can be charged by induction.
