Five World Cup innovations you might have missed
The excitement around this year’s World Cup in Brazil has been ratcheted up a notch now that we’re in the second round of group matches and the United States has already started off with an impressive 2-1 win over Ghana.
While there’s been talk about the innovations in how we watch and follow the World Cup on TV and social media, it’s the technology innovations happening at the game level that viewers need to keep an eye on in Brazil.
1.Goal-line camera technology
One big story at this year’s World Cup is the new goal-line technology that claims to be 100 percent accurate.
What that means is that goals will be called goals at this World Cup, and we won’t have to worry about controversies like we did at the 2010 World Cup, when a ball clearly crossed the line but was not ruled a goal.
The goal-line camera technology (Goal Control) is better than instant replay technology in other sports because it can detect a goal in real-time – no waiting around for the referees to view different angles of a shot on goal and then conduct a conference on the field about a controversial call.
Each camera is capable of taking 500 pictures per second and then instantaneously sending a message to a referee’s watch that a goal has been scored.
