Both Hawk-Eye and GoalRef technology will be used in Japan after each was approved by the International Football Association Board (IFAB) panel. I previously discussed the Hawk-Eye system back in March 2011 relating to the potential implementation of goal-line technology in Gaelic Football. According to ESPN.com, “Hawk-Eye is a British camera-based system already used in tennis and cricket. GoalRef is a Danish-German project using magnetic sensors to track a special ball.”
One important note, this technology comes with a large price tag. The English Premier League will likely soon adopt one of these systems with an expected cost of around $250,000 per stadium. MLS (Major League Soccer) has also indicated an interest in implementing goal-line technology.
However FIFA’s announcements were not just about high-tech modifications today. They also approved the use of 5 referees during matches (the additional refs to be placed beside each goal). Similar to goal-line technology, this 5 ref system was approved in the effort to better officiate the most important part of the game, goals. However the IFAB approval of both goal-line and the 5 ref system are considered purely optional...if a league chooses to use and pay for it. Ref. espn.com
