Sensor-Equipped Footballs to Make Refs More Accurate

Saturday, December 27th, 2008

arush_cmu_footballtech-300x195.jpgAs everyone who’s had a ref make a bad call at their team’s expense knows, NFL refs aren’t perfect. But footballs and gloves with built-in sensors? Those might just make coach’s challenges history.

Dr. Priya Narasimhan of Carnegie Mellon University has developed the football and gloves, loading them up with wireless sensors that can precisely determine whether or not a ball hit the ground before being caught or whether or not someone had control of the ball before fumbling. It could also, using GPS, determine whether or not the ball cross the goal line. But the applications don’t stop there.

Eventually, the same kind of sensors used in the gloves could be adapted to shoes, to measure stride and running patterns, or even shoulder pads, to calculate blocking positions and force.The current version of the glove has 15 touch sensors on the fingers and palm, running to a wireless module on the back of the arm, said Adam Goldhammer of Richboro, Bucks County, a master’s student in electrical engineering at Carnegie Mellon.

Wearable Wireless Sensors Measure Hand Forces

Wednesday, July 2nd, 2008
LOS ANGELES, CA /PRNewswire/ — Pressure Profile Systems, Inc. (PPS) announces their innovative new wireless FingerTPS (Finger Tactile Pressure Sensing) system for immediate sale worldwide. FingerTPS sensors are soft, flexible sensors worn on the hand that transmit accurate, repeatable tactile force data to a PC via wireless Bluetooth connection. FingerTPS tactile data with integrated video provides a complete representation of user interaction with tools, sports equipment, new product designs, or medical applications.”The FingerTPS concept was originally funded by DARPA research grants to capture the forces of a skilled surgeon for developing virtual surgical simulation systems. After a decade of numerous iterations, we finally have a system that is easy to use,” said Dr. Jae Son, CEO of PPS.

The wireless FingerTPS system was unveiled to the public at the IVR Industrial Virtual Reality Expo in Tokyo, Japan on June 25–27, 2008. “The wireless capability and the simple, one-touch calibration were the most exciting features among attending engineers and researchers from hundreds of leading firms,” said David Ables, CTO of PPS.

FingerTPS was recently featured in programming on the National Geographic Channel and Fox Sports Net. Episodes of “SportScience” and “FightScience” called on PPS and industry experts to scientifically explain the performance of world-class athletes including NFL hall of fame receiver Jerry Rice, NBA sharpshooter Jason Kapono, and Mixed Martial Arts legend Randy Coture.

“For elite athletes like Jerry Rice or Jason Kapono, their hands are their livelihood, and they readily grasped how real-time tactile data could help evaluate and improve their performance,” explained Ables.

FingerTPS systems start at $4,995 for a single-hand system with two sensors that are available in multiple sizes in specialized shapes for fingers, thumbs, palms, and inner phalanges. FingerTPS systems also include a video camera for synchronized video input, software, and a reference sensor for easy, one-touch calibration.
