As a fan of professional tennis, I thought it would be fun to create an infographic of the amazing video replay technology that’s used to call lines on the ATP and WTA tours. The officiating system, known commercially as Hawk-Eye, uses an array of cameras that feed three dimensional coordinates of the flight of the tennis ball into a series of networked computers. The calculated position of the ball is displayed on a video screen and is accurate to within a few millimeters. It even accounts for ball deformation upon impact with the court. Many have speculated how to adapt some form of the system to other sports, particularly soccer, where we witnessed some dubious referee decisions at the 2010 World Cup. Granted, a video replay system would interrupt the continuous flow of play that is unique to soccer, but I’m sure the fans of teams that are sent home early because of a blown call would be willing to put up with that inconvenience. Who knows, it might even increase the entertainment value of the sport, as it has in tennis.
