Replays of incidents reviewed by video assistant referees (VAR) will be shown on big screens at the 2018 World Cup.
VAR will be used at a World Cup for the first time in Russia despite criticism of its use in domestic competition.
One issue has been that fans have been unable to see replays shown on television that referees use to make their decision, leading to confusion.
But this summer the crowd will also be told when a decision is being reviewed and why a decision has been reached.
However the replays will not be shown inside the ground while the referee is making a decision, only afterwards so the official is not influenced by the crowd, football’s world governing body Fifa has announced.
VAR has been trialled in some domestic English cup games this season, as well as in Germany and Italy, and Fifa confirmed in March the system would be used at the World Cup, starting in June.
