Setting the VAR: Football’s newest technology

And where better to shine than the 2018 FIFA World Cup

Published

on

The 2018 FIFA World Cup is in full swing, with the last few matches about to take place en route to the Round of 16 on Saturday. While the world’s greatest football players are taking center stage, another main attraction in the tournament is the football world’s latest technology: the Video Assistant Referee.

The Video Assistant Referee or VAR has been adopted in sports like tennis and rugby, and recently by football leagues such as the English FA Cup and the Bundesliga in Germany. Ideally, the VAR helps make decisions for referees much easier and more accurate — especially for crucial, game-changing calls. But is the technology useful and helpful in every possible way?

What is the VAR?

The VAR is a video system that feeds information to referees on the pitch through a wireless earpiece. Assistant referees  gather the information away from the stadium and forward these to the referees when a call is contested. The VAR marks the huge step football leagues are taking to digitize football, and has been used since last year.

It utilizes a goal line technology that allows the cameras in the stadium to scan the pitch at every minute. With this technology, movement on the pitch is detected at all possible angles and calls can be made more precisely. Assistant referees inside a control room have access to all these cameras and they send live feed to the pitch via tablet or iPad should the referees want to look at the footage themselves.

The VAR reviews game-changing calls on the football pitch at the time a protest is filed. FIFA lists only four game-changing calls to be considered: goals, penalties, direct red card incidents, and mistaken identity. The VAR checks the validity of these calls and sends the information to the referees. Do note, however, that the referees themselves still have the final decision on what call to make.

The system made its debut in a FIFA Club World Cup in December 2017 between Atletico Nacional and Kashima Antlers. The referee rewarded Kashima with a penalty after reviewing a play inside the penalty box.

Putting the VAR to work

2017 also saw the VAR’s debut in the English FA Cup, but it had its own set of controversies along the way. During a quarterfinal match between Tottenham and Rochdale, a goal by Tottenham was reversed for unclear reasons cited by the VAR. German football league Bundesliga also utilized the VAR during its latest season, but received mixed reactions from players and fans.

In the 2018 FIFA World Cup, the VAR takes center stage as a decision-making aide for referees in the group stages. The first instance was a non-call on a foul by Spain’s Diego Costa in their 3-3 epic against Portugal. Costa would slice the Portugese defense to tie the game at 1-1 at the time, but did so while taking down Pepe from Portugal. After the review from the VAR, the referee stood by his decision to count the goal.

The second instance happened in the France-Australia game when French striker Antoine Griezmann was tackled inside the box, yet the referee called for play to continue. Griezmann received a pass from Paul Pogba, and virtually blitzed through the Socceroo’s defensive line. Griezmann was awarded the penalty after reviewing footage from the VAR as the French went on to win, 2-1.

The third instance was in the Peru-Denmark game when another penalty was awarded to Christian Cuerva of Peru. Denmark’s Yussuf Poulsen tackled the Peruvian in the box, yet the referee called for the play to continue until the incident was reviewed via VAR. However, Cuerva missed the penalty and Poulsen scored in another possession to give the Danish the win, 1-0.

A VAR too high or too low?

While the VAR has only been around for well over a year, it isn’t exempt from both praise and criticism. Many people have shown their praises for the newest technology applied to the football world. The VAR now adds certainty and legitimacy to calls made by referees during matches, instead of them making the same wrong call every time. With football players and managers focusing on the tiniest of details to improve their game, information from the VAR becomes important.

The VAR provides an opportunity for football games to be fair and balanced. Referees now have different vantage points to look at when making calls that ultimately change the outcome of the game. People came to see a quality match wherein the players truly shine, but sometimes the referee’s poor decisions hamper that. In this regard, there is no excuse for not making the right decision with all the video evidence available.

However, a lot of people also have strong feelings against using VAR. While the effort to make the right calls is appreciated, it gets in the way of what makes football so special. When referees call for the VAR — especially with contested goals — fans become anxious instead of jubillant. Usually, fans go into a frenzy the moment the ball goes through the net — no replays needed. It’s as if the game feels all too unrealistic because of all the technicalities.

For football players and coaches, the VAR only adds confusion to fans. Because some football stadiums are built without any big screens, fans become unaware of what’s happening when the referee calls for the VAR. Iran’s coach Carlos Queiroz lambasted the use of the VAR for close, judgment calls — particularly the offside call on his squad in a loss to Spain. He believes that the VAR was put in place to correct obvious mistakes by referees, not debatable calls.

Final verdict

The VAR is a fairly new technology introduced in the world of football, and surely, it’s not perfect. It’s a bold take on digitalizing football, keeping up with the technological demands of today. Because football is decided by people making the right calls at the right time, the VAR becomes an important part in establishing the basis for such calls. The VAR is a useful solution for referees to make the right decisions on the pitch.

However, we must be critical about how the VAR should play in during very crucial moments in the game. The VAR should help give fans a fair yet exciting football match without losing its spirit. With the Round of 16 coming up, all eyes will be on the VAR and whether it will help make the road to the finals interesting or not.

At the end of the day, football fans came to see the best players in the world do what they do best, and no amount of technology should get in the way of that.

ChatGPT Explained: Should we be scared of AI?

Will the talking robot take over the world?

Published

on

Back in the earlier days of the internet, an emerging but short-lived trend involved chatbots who could generate conversation with whomever it talked to. Does this sound familiar? Today, a similar phenomenon is creating a lot of waves online, headed by the infamous ChatGPT. The exceedingly popular ChatGPT is turning heads out of fear that the technology will eventually upend society and eradicate a lot of jobs.

But what exactly is ChatGPT? How is it different from language programs in the past? Is the world right to worry about them?

On the rise of language learning

ChatGPT is hardly the first software to inexplicably generate comprehensible dialogue without human intervention. Decades ago, the internet hosted rudimentary versions of today’s chatbot technology. The concept is somewhat similar, though. The early versions relied on a database of responses from human users. If you asked about coffee, for example, the answer you get will likely come from the logs of another user who talked about coffee in the past.

Because the system was imperfect in its infancy, part of the appeal was trying to get the software to fumble a conversation. However, if it did mess up, you can count on it asking you what it should have said. The next time someone asks the same question, the software might mirror what you said, creating a learning process between the software and the user.

Today, chatbots — meaning those usually used by businesses today — operate in the same way. If a customer comes with a query, the software will rely on a set of responses to most appropriately address the user’s problem. If the software can’t come up with a solution, the ball usually gets passed on to a human consultant.

Is ChatGPT just another chatbot?

Though the label certainly gets thrown around, ChatGPT isn’t strictly a chatbot. Instead, the software uses GPT-3.5, a specific language model created by OpenAI. Whereas early and more rudimentary versions of the same technology can already store an unbelievable amount of information in its memory, ChatGPT can analyze billions of words and the relationship between them.

Further, OpenAI extensively trains the software, ensuring that comprehension and grammar can live up to today’s standards. The learning is supervised. In fact, the company even has a makeshift reward system to ensure that the software puts out the most appropriate response. With users also contributing to the software’s learning process, ChatGPT is quickly emerging as a powerhouse for the technology.

The results speak for themselves. While users can generate simple conversations with the software, ChatGPT can just as easily answer more extensive queries with lengthier responses. If you ask it to create an essay about Christopher Columbus, for example, it can write a lengthy piece that can easily fool a casual reader. It can even handle more speculative queries. In a sample published by the developer, ChatGPT can answer what would happen if Columbus discovered America in 2015.

What’s it good for?

Based solely on what the software can do, ChatGPT can find its purpose in today’s world. The software can improve voice assistants and chatbots all over the internet. It can make big strides in the world of automation, enabling a more responsive interface between user and software.

On a more human aspect, the software can also handle more professional jobs with simpler prompts such as those involving simple marketing copy. It can help with more ephemeral research efforts, allowing users to get simple answers for otherwise complex questions.

And, on a more technical side, ChatGPT can reportedly analyze and detect what’s wrong with a piece of coding. With the software, developers can use ChatGPT to potentially repair code without having to pore over every single line. Allowing a powerful tool to inspect code speaks volumes for a lot of applications all over the world including smart vehicles and technical machinery.

However, as with every piece of technology, users will always find a way to use something beyond what it was originally designed for. ChatGPT is now changing the world of education as students are using the software to do their homework for them. Though a lot of the sample texts look like they can fool only lower levels of education, a Wharton business school professor (via Business Insider) recently stated that he would have been fooled by a ChatGPT essay, grading a sample with a passable grade of B or B-.

Should we be scared of ChatGPT?

ChatGPT is undoubtedly rocking the world of education. While some schools have banned the technology outright, others are debating on the software’s impact on how schools are taught. Since ChatGPT deals out more factual information, could education reinvent itself to teach more personal, tailored learning, rather than just the ability to spit out memorized facts. (“Factual” might even be an exaggeration. CNET, which recently experimented with AI-written articles, discovered a plethora of errors from using the software.)

Now, education isn’t the only world in peril. The creative industry is facing an extreme challenge wherein ChatGPT can potentially cause workers their jobs. Though the danger certainly seems real, the limitations of technology are also real. ChatGPT can create comprehensible text that can fool a human, but it will likely stumble with conceptualization.

A piece of software is just software. Even if it can write an essay about existentialism, it cannot think of the concept metaphysically. In the same way, even if it can show you a photo of a parrot, it cannot think of that photo as anything but a pattern of pixels. To a language learning software, words don’t mean anything else besides their relationship with each other. It’s the same thought process as a dog learning to run to its human when its name is called. The dog doesn’t know that you just said its name (or even the mere concept of a name); it just knows to do a certain action after hearing a specific sound.

Can ChatGPT change the world? Overall, the jury is still out, but it’s unlikely that a piece of learning software can do much to replace human-centric work. Regardless, it’s important to think of how ChatGPT can improve (or detriment) humanity.

Like with other supposedly dangerous technology, the world of technology is a Pandora’s box. We can never put the genie back into the bottle. Once it’s out, it’s out. Instead of worrying about how technology can destroy the world, the more appropriate response is to figure out how it can better humanity without sacrificing anyone’s wellbeing in the process.

Should you be excited for Apple’s satellite connectivity?

Fad or future?

Published

on

Illustration by Garel Perpetua

If you watched the latest Far Out event from Apple, you might have noticed the debut of a new technology coming to smartphones: satellite connectivity. Though Apple has made the biggest deal of the new feature, the technology has existed even before Apple’s announcement. In fact, various smartphone makers are also announcing their own takes to go along with Apple’s satellites.

But what exactly is satellite connectivity? Before the world gets more of the new feature, let’s take a look at this emerging technology.

Look at the sky

The night sky is filled with satellites. Though you might not see any of them with the naked eye, they are all there in low Earth orbit (LEO). As you might imagine, their uses are aplenty. Most attribute LEO satellites to imaging, navigating, and measuring data. However, one emerging use is the improvement of connectivity for consumer devices.

Now, the biggest proponent of satellite internet is Starlink, a project of Elon Musk’s SpaceX. With over 300,000 satellites, the company’s satellite constellation provides internet to several countries including areas with low coverage. In fact, the company’s services are already somewhat in the Philippines.

Satellite internet does have its benefits. While the service isn’t the fastest, it offers connectivity that regular towers can’t normally reach. Imagine being out on a hike but you suddenly remember, oh my God, you left your stove running at home. Satellite internet will allow you to connect to the internet and notify a neighbor to check if your apartment has any wayward burn marks running up its walls.

Quite a feat, isn’t it? But is this what Apple just launched?

SOS, please someone help me

Contrary to what you might think, Apple’s new satellite connectivity doesn’t offer internet. It’s also not Starlink. Instead, it’s a simple SOS messaging service through the Globalstar satellite constellation. It won’t solve your faulty 5G service. However, it’ll help you in a pinch if you find yourself lost in the middle of nowhere.

Once again, imagine you’re out hiking. Suddenly, you fall down an unseen slope and break your ankle. You find yourself miles and miles away from civilization, and no one knows where you are. Apple’s satellite connectivity can help you send an SOS message to the authorities.

Here’s how it works. When you’re in a predicament, fire up the feature and point your phone towards the satellite nearest you. (Don’t worry; the phone will tell you where it is).

Now, it might take a few seconds to a minute before the phone can connect to a satellite — especially if the skies aren’t clear or if you’re underneath a canopy of trees. It might not even connect if the skies are completely obstructed. Regardless, while it tries to connect, the phone will ask a series of questions including who needs help and if anyone was harmed. This helps the phone craft and compress the necessary information for your message.

Because the service is only for emergencies, you can’t write an essay. Apple says that it will squeeze messages three time as small to ease transmission. It’s a wide-reaching 911 call for when you can’t actually call 911.

After compressing the message, the satellite will then beam the message to a nearby relay station on the ground, which will alert authorities for you.

Who can use it?

Naturally, only Apple users who have the latest devices will have the feature for now. Also, because it’s so new, it’s only coming to the United States and Canada with the upcoming iOS 16 update later this year. Of course, it might arrive to other territories soon after the initial launch.

China, however, is a no-go. Huawei launched its own satellite connectivity, packing the feature in the new Mate 50 series. If you’re in mainland China, you’ll have to use Huawei’s services.

Interestingly, Apple made it a point to say that the feature is free for the next two years. The implication seems clear: Users might have to fork over cash to keep the feature once the two years are up. Now, if you’re celebrating the coming of this arguably essential feature, the possibility of a paywall might leave a sour taste in your mouth. Should companies gatekeep who gets to send emergency messages in their time of need?

Passing fad or the future?

If you’re not a regular hiker, satellite connectivity might not appeal to you. However, it’s still interesting to wonder if the technology will make an impact outside of Apple. And it does seem that way.

It’s no coincidence that a few brands, including Apple and Huawei, have suddenly launched their own satellite connectivity features within a short span. Companies are putting a lot of money into the future of satellites. Very likely, Apple won’t be the last company to adopt the new feature.

Emergency satellite services are essential. Even if you don’t hike, you’ll never know when you might get into a precarious situation without cell coverage. Satellite connectivity mitigates that risk.

Now, how will the technology evolve beyond emergency services? Coupled with the efforts of Starlink, the early stages of satellite connectivity proves the concept of a satellite-laden future. Currently, a lot of services still struggle with the lack of towers in certain locations. The aid of satellites creates a future that won’t need towers everywhere. Though speed might be an issue, connectivity won’t.

That future is quite a possibility. However, it will also come with a host of questions. With space limited to only a handful of providers, will companies launch more satellites to address the potential need? How will space look like then? Will it just be a wasteland of used satellites? How much will everything cost? Though it’s coming, the future still has much to clarify.
