A trio of football-freak scientists has come up with football shirts and football boots that change their colours as soon as a player commits a foul or strays offside. Austrians Christoph Doettelmayer and Joachim Kornauth, and German Svenja Schulz say that their "digital football pitch" technology can also provide goalposts and balls that change colour whenever the ball passes into the net.
The “Digital Football Pitch” will help to avoid crucial problems of the referees’ decision-making in professional football played by FIFA rules. Published in time for the UEFA Euro 2008 in Austria and Switzerland, it quickly gained international media attention, which was additionally raised by very controversial calls by some referees during the championship tournament. The “Digital Football Pitch” applies and uses advanced yet available technology to assess breach of the “FIFA Laws of the Game” by especially taking care of some key issues such as offside, ball over the goal line and out-of-bounds, as well as foul play by pulling opponent’s jerseys.
