Today, adidas and Cairos Technologies presented the new Goal Line Technology and the adidas intelligent football tested at the FIFA Club World Cup™ in Japan from December 7 through 16, 2007. The official match ball of the tournament, adidas Teamgeist II, features a new intelligent technology designed to assist the referee’s decision in determining when and if the ball has crossed the goal line, making it the most accurate football ever produced.
"The purpose of the adidas intelligent ball and Goal Line Technology is to provide greater transparency during a match and to assist the referee in making quick decisions that can impact the outcome and quality of the game" said Hans-Peter Nuernberg, Senior Development Engineer, adidas Innovation Team. "We expect the system to perform very well during the FIFA Club World Cup™ in Japan and we will continue to refine the system so that it is 100% accurate."
The intelligent technology implemented in the Teamgeist II uses a magnetic field to provide real-time feedback to a central computer, which tracks the location of the ball on the field and sends the data directly to the referee. By using a magnetic field and more stabilized and robust components within the ball, the new system is more precise and is not influenced by in-game factors, adverse weather or nearby technical systems.
