New iPhone Technology to Revolutionize Offside Calls in EPL

The Future of Offside Technology in the English Premier League

The English Premier League (EPL) is evolving, introducing cutting-edge technology to refine offside detection during matches. This advancement comes through a partnership with Genius Sports, leveraging a combination of iPhones and machine learning models to support match officials in making accurate calls.

Understanding Offside Violations

Offside calls in soccer are often challenging due to the dynamic nature of the game. Players can cluster together, obstructing the view of match referees and even multiple camera angles. Historically, video assistant referee (VAR) systems have been employed to bridge these gaps by utilizing video feeds and machine learning.

Why Genius Sports?

Genius Sports is pioneering a new system known as Semi-Assisted Offside Technology (SAOT). As explained by chief product officer Matt Fleckenstein, this technology is part of the broader GeniusIQ system, which also enhances fan engagement through dynamic graphics highlighting gameplay.

The Technology Behind SAOT

• Genius Sports uses an array of 24 to 28 iPhones (primarily the iPhone 15 Pro) to cover the pitch effectively.
• This approach captures between 7,000 and 10,000 data points for generating a detailed 3D virtual representation of every player.
• The iPhones record footage at high frame rates (up to 200 fps), ensuring accurate captures of critical moments.
• Data is processed via GeniusIQ’s advanced predictive algorithms to identify player positions, even in obstructed scenarios.

Benefits of Using iPhones in SAOT

Shifting from traditional high-cost cameras to iPhones serves several purposes:

• Cost-effectiveness: iPhones are more accessible and flexible.
• Familiarity: The development team is well-versed with the iOS platform, enhancing software integration.

How Does SAOT Compare to Existing VAR Systems?

VAR systems have been utilized for over a year and often rely on a limited number of metrics for offside calls. In contrast, Genius Sports claims:

• The SAOT can track individual body parts—down to players’ fingers—using approximately 30 to 40 anatomical points.
• This granularity enables a higher degree of accuracy compared to systems that represent players with a single point or center of mass.

Implementation Timeline

The full deployment of Genius Sports' SAOT technology is anticipated before the end of the current EPL season. Although a specific launch date remains undisclosed, the football world eagerly awaits to see if this tech can deliver superior performance over traditional VAR systems.

Conclusion

As the EPL embarks on this technological leap, the effectiveness of Genius Sports' offside detection technology will be under scrutiny. With faster and more accurate data capturing capabilities, the game may experience a shift in how offside calls are made, potentially elevating the overall viewing experience for fans.
