Using this system, sports figures in a TV picture are traced individually and their positions transformed in real time, just as if they were being tracked by a camera installed over the playing field. The system can display accurately the formation of a play as the loci of players on the screen, and it may also be helpful and instructive to people unfamiliar with the sport.
