Magneto-Track System

 Magneto-Track System: 3D Tracking of an American football location and orientation

Referees may soon have a new way of determining whether a football team has scored a touchdown or gotten a first down. Researchers from North Carolina State University and Carnegie Mellon University, in collaboration with Disney Research, have developed a system that can track a football in three-dimensional space using low-frequency magnetic fields.

The technology could be particularly useful for situations when the ball is blocked from view, such as goal-line rushing attempts when the ball carrier is often buried at the bottom of a pile of players. The technology could also be useful for tracking the forward progress of the ball, or for helping viewers follow the ball during games with low visibility – such as games played during heavy snow. See the videos below that demonstrate the system in action. Research publications can be found at the bottom of this page.
