Whether you call it หาข้อมูลเพิ่มเติม or soccer, the game is using technology to make sure that things are done right. For example, you may have heard of goal-line technology that was used two years ago at the World Cup or of electronic performance trackers that are being used by professional players. But the most significant change that has been made to the way the game is refereed has come from VAR or Video Assistant Referee.

VAR is a system that allows for more accurate refereeing of important events in a football match. It involves a team of officials monitoring the game from a room full of screens that use multiple camera angles to review incidents. They then pass on the information to the main referee in a stadium, who can choose to ignore the recommendation or change his original decision.

VAR and Beyond: The Growing Role of Technology in Football Refereeing

The system is being used in association football and has undergone extensive testing. There are two different systems available, including one from a U.K. company called Hawk-Eye Innovations and another from Germany’s Cairos Technologies AG. The system uses a number of cameras to capture images of the ball and sends them to an image-processing computer. The system determines whether the whole ball crosses the goal line and sends a signal to the referee’s watch that indicates a possible match-changing decision needs to be reviewed.

While the research shows that VAR improves refereeing accuracy, some critics argue that it has added a layer of complexity to the game and has contributed to heated debates over what should and shouldn’t be allowed in the sport. This article takes a closer look at VAR and how it has changed the game of association football.
