#229 Is Sportsbox AI 3D Accurate?⁠

A Discussion on Golf Analysis Technology

In this episode, we explore the accuracy and applications of Sportsbox, a 3D biomechanics analysis system for golfers. Based on the YouTube video titled "Is Sportsbox Accurate?", three experts compare Sportsbox's data to other systems like AMM, a gold standard in biomechanical research. They delve into the system’s data verification, functional accuracy, and measurement consistency. Key factors such as camera setup, lighting, and player attire for optimal use are also discussed.

● Accuracy as a Priority: Sportsbox continuously updates its technology with rigorous accuracy tests to ensure reliability. The team views accuracy as essential for making the software a trusted tool, not just a novelty.

● Algorithm Comparison: Sportsbox uses the same algorithms as the AMM electromagnetic system, allowing direct comparison and a deeper understanding of accuracy or potential errors. It’s important to remember, however, that no system is perfect—each, including EMS and optical systems, has its own margin of error.

● Functional Accuracy: Sportsbox delivers high functional accuracy, with motion curves closely matching expected golf swing patterns and aligning with AMM data. The system captures key swing metrics such as chest rotation, chest flexion, side bend, club shaft angle, club face angle, and swing speed.

● Data Consistency: Across 30 swings, Sportsbox's measurements differed by an average of only 2 degrees from AMM and about half an inch in linear measurements, demonstrating strong agreement. Variations in chest and pelvis rotation showed slight differences but remained consistent.

● Comparison with Foresight: When comparing clubhead speed across 480 swings, Sportsbox differed from Foresight by an average of 1.6 mph. Notably, both Foresight and Trackman show similar deviations due to differing methodologies.

● Consistency in Swing Variability: A study of three professional golfers taking 10 swings each with a 6-iron demonstrated that Sportsbox closely matched AMM in measuring swing-to-swing variability, highlighting its reliability in tracking incremental changes.

In conclusion, Sportsbox offers a high level of accuracy and consistency in comparison to other analysis systems. The developers prioritize ongoing improvements and validation, making Sportsbox a trusted tool for golf swing analysis. While no system is flawless, it provides valuable insights when used alongside a coach's expertise and other assessment methods.
