Motion Tracking System MotionWorks: Putting RFID in Football Players’ Shoulder Pads

I believe most people are no strangers to the practice of using radio frequency identification (RFID) chips as anti-counterfeiting labels in clothing stores, and now you can find them in NFL players’ jerseys.At last weekend’s London game between the Atlanta Falcons and Detroit Lions, Zebra Technologies will be based on RFID The motion tracking system MotionWorks was also brought into the game.
As the main supplier behind the player tracking system used by the NFL, Zebra Technologies has installed wireless location receiving equipment in 17 NFL venues across the United States, and it will cover all 31 venues in the future. The company hopes to use this game. Convince the operator of Wembley Stadium or other sports leagues to follow the NFL’s lead and use its MotionWorks motion tracking system in games.
As a new type of motion tracking system, unlike SportVU, which is provided by Stats LLC, which is used by the NBA, MotionWorks does not collect player positioning data through cameras. The receiving device collects player information. The information collected includes player position, acceleration, total running distance and direction, etc. and its accuracy is also very good. At present, the error can be controlled within 6 inches, and the delay is also controlled within half a second.
So what does the powerful function of MotionWorks bring us? Of course, the most obvious one is that it can bring a lot of data to coaches and data analysts. So far, coaches can refer to this series when measuring player performance. The data is more objective in evaluation, and this also helps coaches conduct targeted training and tactical arrangements. Vishal Shah, vice president of NFL media strategy, said:
Zebra’s motion tracking system can help teams further optimize training content and create more logical offensive lines based on each player’s ability.
Referees may also be able to determine whether a player has committed a foul based on the trajectory data collected by MotionWorks. Unexpectedly, sports programming has also become a beneficiary of MotionWorks, as audiences increasingly like to watch accurate data analysis, especially those fans who are extremely obsessed with a certain sport.
In addition, MotionWorks is more durable than its GPS-based counterparts, requiring only one installation for years of continuous use, and the 6.4GHz ultra-wide band avoids interfering with other wireless devices .
And Zebra Technologies’ ambitions are not limited to this. At present, the company has tested the addition of low-power Bluetooth devices to RFID, so that the system can collect more information on athletes, such as heart rate and other information will be included, I believe More and more feature-rich MotionWorks will appear in more events.
In the end I think as Steve Hellmuth, the NBA’s executive vice president of operations and technology, said when he announced a partnership with Stats LLC to introduce motion tracking technology across all stadiums:
We are a data-driven league, and our expanded partnership with Stats will give teams and fans access to more groundbreaking stats than ever before. And in an age of statistics like this, SportVU is an invaluable resource for basketball insiders and our passionate fans.
Perhaps in the future, more sports leagues will realize this, and more and more events will use this technology to collect data on athletes.
