World Cup is not just merely about football. There are a number of interesting technologies that adorn the four-year event.
World Cup 2018 not only presents football matches in it, but also a number of technologies that make it more interesting to follow. The referee, the court on the green field, can be considered to be a figure equipped with the most technological qualities.
Applied technology was touched many aspects, ranging referee equipment, wicket, until the ball match. This, in addition to assisting the referee in making decisions, also increasingly enliven the four-year football game.
# 1. VAR
Asisstant Referee Video (VAR) is a system that includes 13 referees during the 2018 World Cup event. Out of a dozen people, an officer is selected as the main decision maker and three assistants as assistants for each match.
At a hub in Moscow, Russia, officers will observe the re-occurrence of every event in the game through a number of cameras with different viewpoints mounted in the stadium. Slow motion recording was also presented to assist officers in making decisions.
Observations are only made when the refs or officers at the hub see the strangeness. Both are equipped with communication lines with fiber-based radio systems. The same communication path can also be used by the referee to make contact with two linesmen in the field.
The goal of the VAR itself is to assist the referee in making decisions regarding four events on the pitch, ie goals, penalties, direct red carding, and ensuring the player sentenced is correct. The viewers who watched on television can also see the decision-making process through the VAR when the referee saw the screen on the field.
# 2. GLT
Not enough just with the VAR, the referee was also assisted by Goal-line Technology or often shortened to GLT, which utilizes Hawk-Eye system. The system uses sophisticated cameras equipped with sensors to detect the ball and the movement of players per millimeter to ascertain whether the ball has crossed the goal line or not.
The function of this technology is to assist the referee in determining whether a goal occurs or not. The main requirement of the goal is the ball has crossed the goal line completely, not just the majority of its course.
GoalControl became the party responsible for delivering GLT to the 2018 World Cup. The German company uses 14 high-speed cameras so there are seven cameras aimed at each goal.
Dozens of cameras will track the movement of the ball, turn it into a three-dimensional view, and determine whether a goal has occurred or not. The system owned by GoalControl only takes one second to undergo a series of processes and send its decision to the referee in the field.
To receive the message, the court is equipped with a special smartwatch that gives notification of the decision of the system, whether it shows a goal or not. Smartwatch itself runs Android Wear OS and is manufactured by Hublot, for a price of USD 5,200.
3. Telstar 18
Telstar 18 is the official ball used throughout the 2018 World Cup. Its name is taken from a series of identical communications satellites. The first satellite of the series to touch orbit named Telstar 1. NASA and Bell Telephone (now AT & T)
satellites were flown in 1962. The ball design also follows the satellites with black and white dominance. In addition, this color is also selected as a repetition of the original version of Adidas Telstar, which was used in the 1970 World Cup. The panel of the ball is also decorated in white and black to appear on television which at that time did mostly accommodate only two colors.
Telstar 18 features a panel design with pixel patterns that have longer lifetimes. In addition, the form of a panel that resembles a fan form is also presented to help the ball float more stable when in the air.
NASA also has its own share in this ball. The US space agency explains the Knuckle Effect theory. This theory explains when the ball is kicked with a protruding part of the bone on the toes, then the object will float with very little rotation, or no rotation at all, so the movement becomes difficult to guess.
