According to Wired, the new system, called Dragon, was developed by sports data and technology companies Genius Sports and Second Spectrum.
From the 2024-2025 season, the Premier League will use dozens of iPhone 14 or newer to analyze offside situations to assist referees.
The Premier League will use VAR in all matches starting this season to replace offside decisions.
The new technology relies on at least 28 iPhone 14 or later phones placed around the field. The devices will be encased in waterproof cases and equipped with cooling fans for long-term operation. The cameras will record high-frame-rate video from multiple angles on the field and transmit signals to the control room. The positions of the Apple phones may vary from field to field, but they will be fixed during the game, avoiding the need to recalibrate the control software.
What makes Dragon unique is its ability to track massive amounts of data for each player. The system can track between 7,000 and 10,000 points on each player, recording details like body contour, muscle mass, and even bone structure.
In addition to improving accuracy and reducing controversy in offside detection situations, Dragon can add many other uses in the future such as creating digital copies of players to analyze actions. They can also be used to support referees in other situations on the field such as blowing penalties and issuing cards.
The company behind the iPhone says it is as powerful as a supercomputer was more than 20 years ago. While other modern optical tracking systems require expensive fiber optic cables, servers to connect them, and computers to manage the data collected, a $1,000 smartphone can handle both tasks quite well on its own.
The Premier League is famous for its wealth, so the choice of Dragon does not necessarily come from its reasonable cost. Genius Sports' solution brings new technology, is easy to deploy and helps replace part of the VAR technology that has been controversial for nearly 7 years of application.
