VAR technology caused a lot of controversy with fans (Part 1)

The famous long-time referee Cüneyt Çakır created a lot of controversy with a penalty rejected after watching VAR’s touch-screen ball by Marco Rojo. Taking advantage of the rush, many “young knowledge” on this opportunity took advantage of criticizing the VAR system and said that it was … “unfair”.

I don’t know where their thoughts originate from, maybe they think it’s unfair, or simply VAR is the reason why their favorite team or player loses or comedy. funnier than they lost because of VAR, so they hated it  feeling it hated it, it was wrong.

Actually, VAR is Video Assistant Referee, which is a system of arbitration assistance, it only helps and not decides to replace the referee  need to make this clear.

And with the referee still making the decision then if the decision is wrong (such as the case of Marco Rojo) then the “unfair” that you are criticizing as usual it must target the referee What is the reason to blame VAR?

It is like your home security camera can record a thief scene but the police cannot catch the thief from that document  then you think that security camera “does not guarantee security”, “does not catch. thief ” god! The security camera only helps but it does not catch the thief itself, the thief is a police job like the final decision is the referee’s job.

VAR is different from hawk eye, hawk eye can decide the result by itself, but VAR is not.

VAR is just a tool to make football matches more fair, and whether football is really fair or not, it still depends on the system’s users, or the way we use it. that system. Although it is not 100% fair but it is clear that VAR is a great step to improve the football environment a lot more than before, this is a good thing for football, can not be used to think.

If the VAR system is widely introduced into the football competitions after this World Cup, it is likely that the meta of football will change completely like the new offside rule has ever done.

Sign 2: In some situations, the referee will draw a rectangle into the space, referring to the TV screen to request information from VAR. After receiving the information, the referee draws another rectangle to continue the match.

Signs 3: most noticeable but also annoying to the audience. Referees will go to the screen located behind the pitch to watch videos, discuss with video assistants.

The referee watches the video back at the screen after the pitch

Later The decision is made, and there is still a rectangle drawn for the game to continue. This is how referee Cunha decided to give France the last penalty.

Why is VAR so controversial?

It takes a long time for VAR to be applied. Most of this stems from technological fears that could lose the natural emotions that football brings.

Opponents say VAR will cause referees to stop the match continuously to watch the video. In addition, when all “injustice” is lost, football will no longer be controversial after that, which is one of the things that make the sport attractive to the king.

But supporters also have their reasons. According to the Chief Executive of the British Professional Arbitration Association (PGMOL), Mike Riley, VAR will only be used when a turning point of the match occurs, without the referee having a favorable view. .

VAR technology is controversial at the 2018 World Cup

When FIFA officially “approved” for VAR “to attend” this year’s World Cup, fans hope this technology will help the referee make the fairest decision to find the team that deserves to win.

Up to now, the 2018 World Cup group stage is about to end and there have been many situations where VAR has directly intervened and caused controversy.

The Swiss goal was controversial because the referee did not rely on VAR support.

Australian coach Bert van Marwijk expressed his dissatisfaction when referee Andres Cunha gave France a penalty after reviewing VAR technology.

The ball was controversial when Harry Kane was “dumped” by the Tunisian player

VAR has had a great impact on many matches and stirred up a series of debates even though it was only the first time it was applied in a world football.

 

 

 

 

 

 

 

 

 

 

 

How did VAR work at the 2018 World Cup? (Part 1)

Despite the outstanding advantages, but not everyone supports VAR. A group of people who regularly come to the field said they were unsure when a decision to use VAR was reviewed. Meanwhile, other groups think that despite the intervention of machines, controversial situations are always a part of football.

One of the biggest differences of the 2018 football festival in Russia compared to previous World Cups, is the introduction of Video Assistant Referee (VAR) technology – the video technology that supports arbitration.

There are 13 video assistants, or extra referees, who sit in a special center in Moscow (regardless of where the match takes place) to watch the match through the screen. Among them is an assistant selected for each match, who will work with a team of three other assistants on duty on the field.

The assistant referee sits in a special center in Moscow

Here, the signals are streamed directly from the stadium, including the full view of the game going on as well as slow motion footage. These video assistants will notify the umpire whenever a fault is found, or the umpire will seek their input whenever necessary. However, the final decision still rests with the referee.

What can viewers see?

Audience present at the stadium: They will not be able to see the influence of VAR most of the time, apart from the rectangles drawn by the referee.

TV Audience: They watch the slow motion, the image is similar to what the referee sees.

How to identify a decision is influenced by VAR?

The entire VAR technology is focused on building around the referee, otherwise the eye will sometimes be inaudible to the audience when VAR is being used. However, there are still 3 signs to know the referees are consulting information from VAR.

Sign 1: In some cases, the referee simply receives a notification via headset from the VAR arbitration assistant. If observant, the audience can know this when the referee touches the headset.

Referees receive notifications via headphones from the VAR arbitration assistant.

VAR is most used in the area of ​​the penalty area. The decision to blow a penalty may be maintained or canceled by the referee after reviewing the video of the situation provided by VAR.

Using Var in direct red card situation

Violent acts will be prevented by VAR. However, VAR is only applied for direct red card situations, not the second yellow card.

Using Var to identify mistakes

In fact, there are many situations on the field that the referee also makes mistakes. Specifically, in the match between Arsenal and Chelsea in 2014. Oxlade Chamberlain of Arsenal was the one who made the mistake but the referee suddenly chased Kieran Gibs, another player who also owns the same head as Chamberlain. Using VAR technology, the mistakes of the referees can be corrected. However, VAR also has certain restrictions to ensure not to interrupt the game.

Application of Var technology in situations: 11m free kick, identify errors, goals and red cards directly.

Is VAR restricted to use?

Not at all, but VAR will not be used in case the game has been continued. If VAR does not detect errors, a free kick, a throw-in is automatically continued.

Goals are not determined by the VAR in the event the offensive team commits a foul in the situation leading to the goal. In general, using VAR, the referee can cool the player even though the foul situation has happened before.

Why is FIFA using VAR at Worldcup 2018?

The world’s most powerful football authority wants to improve the accuracy of decisions on the field. “I will tell football fans that this technology has a positive impact,” FIFA Infantino President said. According to the head of FIFA, VAR has been used in about 1,000 matches with an accuracy of 93-99%.

FIFA scrutinizes all the potential that this technology can bring. Infantino also said that VAR needs to improve the pace of the game analysis and communicate to the referees.

The arbitrator may consult the VAR referee team through a headset without having to review the screen.

Where to use Var?

The referee will signal using the Var technology by drawing a rectangle. The central control room will recreate two video streams and stream them to the game field, where the match is taking place with the following content.

The first video will cover every angle reviewed and analyzed by a team.

The second video from the central control room shows the team’s work here to ensure transparency.

Based on two videos provided by the central control room, the referee refuses to review them with a screen placed close to the football field, from which the referee will make the most accurate decisions in sensitive and easy situations. causing controversy in all matches that took place during the 2018 World Cup.

The central control room will always monitor each situation and developments on the pitch, not just when asked by the referees to support a given situation. The central control room will even contact the referee when a clear situation or serious error occurs.

Var technology in football has also been tested in the UK and some matches in Germany and Italy before being officially applied at Worldcup 2018. This is also the first time VAR is used in a Worldcup. Previously, FiFa also applied the goal line technology for the first time at Worldcup 2014.

In football, when is VAR used?

In a football match VAR is only used in certain situations that are: penalty kick 11m, identify errors, goals and red cards directly. Details are as follows.

Use Var to determine goals

When a team claims a goal, the referee will ask to use VAR to detect offside, pull shirts and other errors during the scoring process. And goals will not be accepted when the culprit offside offside a few centimeters.

What is VAR? How to apply Var technology in football? Invite readers to find out the most complete way about Var technology in the article below of Kienthucbongda.com

On the pitch, there were a lot of unclear ball situations: situations that the spectator or player saw but the referee didn’t see or the situations the referee saw but the player and the audience were confused. It’s a mistake or just an accident, causing a controversial situation. To overcome this, VAR technology was born to ensure transparency in competition.

So what is VAR? How to apply Var technology in football? Invite readers to find out the most complete way about Var technology in the article below of Kienthucbongda.com

WHAT IS VAR TECHNOLOGY?

VAR stands for Video Assistant Referee, a technology that helps referees in football to help the referee make the most accurate decisions.

What does football VAR technology include?

VAR technology includes a system with multiple cameras from different angles to monitor each movement around the ball.

In addition, support for VAR technology also has a central control room (located at IBC International Broadcasting Center located in Moscow), which has a professional team to help analyze each frame and every action. of the player.

VAR information system

In the video observation room, in addition to the referee and the assistants will have a FIFA expert join. This expert is given maximum access to information exchanged between the arbitration and the VAR team, from which this person will be tasked with coordinating technology application situations through a dedicated tablet device. . The system also transmits information to TV tuners who are on live broadcast so that sports commentators can get instant updates from the match.

With the ability to access all cameras placed throughout the yard. The VAR system will give notice to the umpire in case an error is found. The referee on the field receives a signal from the video referee through a headset. He will then signal a pause in the match and let the players know that a decision is being considered. If the referee determines that a situation is free of errors, the referee will allow the match to resume.

 

 

 

 

 

 

 

 

 

How are sports and technology good to work together?

Sports including a lot of subjects like football, including golfing, started to be caught up in the development and “invasion” of technology. It can be seen that in every aspect of life, technology can penetrate, not just sports.

But what is the beauty of sport? It is the admiration for the ability to handle, technical players. Strong opposition or strong agreement with the arbitration’s judgment or tingling stories about a situation where a shooting angle on television cannot express clearly.

For example, golf is also applied virtual golf room or equipment mounted on the sticks to analyze the shot of the player has created many objections. Those who disagree that technology will destroy the inherent nature of sport.

For more comments on this issue, I contacted a long-time golfer, to ask him if technology would change the nature of sport.

He shared with the general idea as follows: Technology or technology equipment, obviously they are very useful for sports players. If football has equipment for analyzing player scores, so does golf. Smart cameras, intelligent measuring devices have been developed and have been added to golf.

But they only stop at analyzing the swing or other factors during training. While playing, according to the expert, all must be removed from the game so that the true nature of golf is not affected.

“Using technology to serve during training is good, but used during competition, I do not support and do not want to bring them into golf”.

Conclusion

Thus, we can see, technology and sports and life can work together. But should only stop at a certain level. What happens when playing football, the decisions made by the machine to 100% accurate and we have no emotional moments in an argument?

Or like golf, thanks to the technology, the story goes exactly 1 stick and the ball will enter the hole will be easy because the equipment has analyzed it all to get this. Thereby the sport becomes more calculated and also loses the surprise and joy because in the past, not everyone had the opportunity to do this.

 

 

 

 

 

 

 

MU starts using the facial recognition technology instead of tickets

Man City experimented with facial recognition technology instead of tickets to the Etihad stadium.

Man City is experimenting with face recognition technology to replace tickets for the field to watch Pep Guardiola’s team play at Etihad. In a pilot plan, Etihad will set up a super-fast entrance to the pitch for NHM. This project will be implemented by Blink Identity, based in Texas, USA.

According to the design team in charge of the project, the technology they applied can scan 50 faces within a minute, can identify whether fans are allowed to enter the yard and the notification signal is displayed by the indicator light system.

The system of Blink Identity will not have the familiar turnstile but will display green if the access is valid, and a yellow display means that the fans cannot enter the field.

To be able to enter the pitch through Man City’s facial recognition system, fans need to access an app via phone, take a selfie and register. Man City’s use of this technology is to prevent ticket sales and transfers all season long.

Man City experimented with facial recognition technology instead of tickets to the Etihad stadium. Face recognition technology will be applied by Man City instead of traditional tickets

This is not the first time Man City has applied new technology. Last season, Pep Guardiola introduced Artificial Intelligence (Al) technology during training with the SAP Challenger Insights application, which allowed him to keep track of the players’ data.

Etihad Stadium has also used 360-degree rotating cameras, Intel’s 3D True View technology can bring a better experience for NHM to watch through television. Outside the Etihad Stadium, Man City also built “CityPulse Wall,” a large interactive screen that gives NHM the opportunity to analyze data and data.

Man City is also the first English Premier League team to broadcast the match using Virtual Reality (VR) technology.

Certainly, there are lots of useful information you can get from wearing smart shirts, in which heat maps are a favorite part of many players. What to consider when wearing a shirt is the time you start and stop (to be as accurate as possible) plus that you need the internet to notify the system exactly where you are playing on the field. This helps organize all the information in the real field of the game field such as travel distance, travel speed, etc.

SmartVest is designed to fit nicely on your body, wrapping around your chest and upper body. It can be worn directly or you can wear it through a T-shirt. It is important that you can wash your clothes after each wear.
