NC State researchers look to cross the goal line with technology

Too often, talk around the water cooler on Mondays involves this wronged football fan griping about that blown call by the refs. (Luckily, that’s not the case for NC State fans today, as the Wolfpack rolled South Florida on Saturday, 49-17).

But technology that NC State researchers have introduced may help to mute some of the grumbling and Monday-morning officiating.

David Ricketts, associate professor of electrical and computer engineering, and Dan Stancil, department head for NC State’s Department of Electrical and Computer Engineering, are part of a team that developed the Magneto-Track System. It’s technology that helps television viewers track the football with their eyes when they’re watching a game.

“It’s not meant to replace the chain, but to enhance the viewing experience,” Ricketts says. “When the quarterback hikes the ball, you don’t see it. The next time you see it, someone’s running it or the quarterback is throwing it.”

The research began at the Disney Research Lab at Carnegie Mellon University, where Ricketts and Stancil taught before coming to NC State. Ricketts says they were trying to do some research with sports visualization, and since Disney owned ESPN, it made sense that the team turned to football.

How Magneto-Track works is pretty easy to understand. There is an antenna inside of the football, wrapped around the belly of the ball. Also enclosed under the pigskin is a transmitter, which can be picked up by various antennae set up around the field.

The exchange is predicated on a magnetic field, not radio waves. “Why that is important is that radio waves, like with cell phones, get blocked by people,” Ricketts says. “But with magnetic fields, it goes right through. We can figure out where the ball is.”

An antenna and transmitter are placed inside of the football under the pigskin, making the tracking possible.

Ricketts believes the technology is ideal for situations where the ball goes missing at the bottom of a pile on a goal-line stand or at the bottom of a rugby scrum. In fact, he adds, one of the leading rugby manufacturers in Europe has expressed interest in adding the technology to their balls.

But as of now, there’s not any discussions between the researchers and the NCAA or the NFL to introduce Magneto-Track to their respective games.
