“Transform” into WWE stars with augmented reality technology

Facebook created a set of 7 augmented reality (AR) filters on the Spark AR Studio app on the occasion of FOX’s first broadcast of Smackdown.

October 4 will be a very important day for WWE in particular and the followers of American entertainment wrestling in general as it battles the 20th anniversary of the WWE Smackdown’s “hit” program. More notably, this event will be the first professional wrestler show that has been broadcast on FOX’s channel since 1993. In the past, FOX has also broadcast RAW, Smackdown and Hall of Famers. and Legends.

To mark this memorable milestone, FOX Sports Television teamed up with Facebook to create an additional set of 7 augmented reality (AR) filters on the Spark AR Studio app. Accordingly, users of Facebook and Instagram can put their faces on the wrestlers in the WWE video, enjoy themselves performing the tricks and gestures of the characters as people fly through the ring. by The Undertaker or the flattering look of Charlotte Flair in a lovely robe.

Spark AR Studio is about to have another 7 filters on the occasion of FOX airing Smackdown.

Appearing on Facebook since 2017, Spark AR Studio has just appeared on Instagram in August this year. Up to now, several revealed characters will appear in these 7 filters including The Undertaker, Triple H, Randy Orton and Charlotte Flair. The identity of other wrestlers will be announced in the coming days. Meanwhile, FOX Sports is also testing the above filters before officially releasing them on social networking platforms.

Smackdown was the first broadcast program in WWE in 1999, Smackdown is the second most “WWE” program in the US, second only to Monday Night Raw. SmackDown even broadcasts more numbers than the most famous shows in “Flag of the United States” such as The Simpsons, the Gunsmoke, Lassie or Monday Night Football.

Over the past 20 years, SmackDown has been the launch pad for many wrestlers, even helping them promote their names in other fields such as Dwayne “The Rock” Johnson, John Cena, Triple H, ” Stone Cold ”Steve Austin and The Bella Twins.

The great technology invention that quickly help runner recover (Part 1)

The extremely affordable body weight support LightSpeed ​​Lift and Lever Lyte-V contribute to the runner’s exciting treadmill treadmill experience.

A few decades ago, running a treadmill underwater was almost the only option in supporting body weight for athletes to recover from injuries. To be able to experience it, the athletes must “line up” to the Recovery Centers or hospitals.

Everything changed only when AlterG zero gravity treadmill appeared in 2005 with a lot of modern features. However, the price from 25,000 USD to 59,900 USD is really a “super huge” challenge for fitness centers, not to mention the runner.

Recently, Runner’s World researchers have introduced two devices with extremely affordable prices and features that are not inferior to AlterG.

LightSpeed ​​Lift

The body weight support system LiftSpeed ​​Lift uses technology “Lift from the Hip” to provide the necessary support for runner at the axis of motion.

Lightspeed Lift has a chassis similar to the power rack that is placed around the treadmill treadmill. Besides, the ropes connect the frame to the hip of the user via the belt or the waistband of tight pants.

How to use LightSpeed ​​Lift

Users only adjust the 2 metal horizontal bars according to the steps are predetermined on the frame until the body weight reduction to reach the desired level. This will help users to reduce the impact load from 20 pounds to 40 pounds (from 9kg to 18kg) when running without causing discomfort when transporting their arms and extending stride.

LightSpeed ​​Lift was launched in 2011 when physical therapist Malcolm Macaulay wanted to help patients with serious neck injuries to relive the passion for running. Since then, Lightspeed Lift has become a “valuable remedy” for many athletes in the process of recovering from injuries.

LiftSpeed ​​Lift uses “Lift from the Hip” technology to provide the runner with the support they need at the moving axis.

VAR at Premier League 2019/2020 season made 4 mistakes

The British professional arbitration board admitted that VAR made 4 mistakes in the first 12 rounds of the 2019/2020 season.

VAR Premier League made 4 mistakes that made MU benefited while Chelsea and Arsenal were disadvantaged.

Mr. Mike Riley, General Director of the British Professional Arbitration Board (PGMOL) had a meeting with representatives of clubs to assess the use of VAR in the first 12 rounds of the English Premier League this season. He acknowledged that of the 28 referees who changed their decision thanks to VAR intervention, four were “wrongly whistle-blown”.

Among the errors mentioned, there were three penalties for MU (against Norwich), Brighton (against Everton) and Watford (against Chelsea), PGMOL acknowledged that those collisions were not fouls. The remaining situation is Arsenal’s unrecognized goal against Crystal Palace, VAR caused the referee to penalize Calum Chambers.

The 2019/2020 season is the first season the Premier League uses VAR.

VAR’s singular errors remind fans that this is not exactly the right and wrong technology like Goal-line or Hawk-eye, calling “VAR technology” wrong. VAR is a team of referees who analyze multi-angle video footage to advise the referees to avoid making mistakes in key situations of the game (e.g. leading to a goal, penalty or red card).

“We are still far from reaching perfection and improving our way of doing things,” said Mike Riley. “The worst case scenario is when the referee on the pitch makes the right decision but VAR intervenes again leading to the wrong decision. There is still a lot we need to do to improve efficiency.”

The former Premier League referees said that not using the screen outside the boundary to allow the referee to personally watch the video did not seem to be a reasonable choice. PGMOL and the Premier League Organizing Committee will study more options to reduce the time of interrupting the match when VAR intervenes, and minimize errors.

Why OLED screen phones can cause eyestrain and headache?

Sometimes you experience eye strain, headache, for too long looking at an OLED screen, possibly due to something called Pulse Width Modulation (PWM). This article will help you better understand it.

OLED technology is widely used on smartphones for many advantages, such as dramatic contrast, deep blacks, thinner and lighter LCDs. However, OLED screen phones are using the method of reducing screen brightness as Pulse Width Modulation (PWM).

This is different from LCD screens that use DC dimming, and it makes some users feel uncomfortable. So how are they different? Why is PWM annoying a small group of us and DC dimming is not?

How does PWM work?

This technology simply means changing the width of the light pulses, thereby increasing or decreasing the screen brightness. The frequency of light pulses is often very high – 200Hz and above – making it impossible for the human eye to recognize each individual pulse. Therefore, we will receive the average amount of light that these pulses emit.

The state of the screen turned off or on is actually determined by the amount of light it receives. When you reduce the screen brightness, in fact, the off state lasts longer than it turns on, the amount of light generated by the pulses decreases so we think that the screen is darkened.

At 100% brightness, you notice it’s always bright because the pulse is at its widest. When reduced to 50%, the panel emits shorter pulses, divided into intervals that reduce the amount of light received. And if you continue to lower the brightness, the pulse amplitude will be shorter, the screen stays longer. At extremely low brightness levels, the spacing between the pulses is large enough for them to be discrete and visible to the human eye. At this time, flicker occurs.

Most people are not sensitive enough to recognize this screen flicker. Only a small group felt uncomfortable, although they did not know where the cause was. With this group, flicker for a long time makes the eyes faster tired, headache or migraine. Especially with the habit of using an OLED screen smartphone in low light conditions, or at times when the eyes should rest – for example, before going to sleep – is not as good.

Why don’t commercial planes fly higher into space?

The higher the flight, the more fuel-efficient the aircraft is, the faster and quieter it flies. But they can’t fly into space because of some design limitations.

According to ScienceABC, commercial aircraft usually fly stably at an altitude of 10,700 m above the ground. This is considered the ideal height to help airlines save money, fly faster and safer.

There are three main reasons for this.

The higher the flight, the thinner the air density. This helps reduce the drag of the aircraft. Besides, the air pressed down into the fuselage is also lower than the lifting air.

At the same time, the aircraft must also move faster to gain additional lift of the air. So when traveling at high altitudes, the aircraft will consume less fuel and fly faster.

Because of some design limitations, civil aircraft cannot fly into space.

Another reason is comfort. An aircraft can fly at altitudes of 10,700 – 42,000 m from the ground. Weather phenomena are most influential at altitudes of 0-10,700 m.

If flying at this altitude, the aircraft will not be affected by such turbulence weather. This helps passengers experience a softer and more comfortable flight.

The last reason is for everyone’s safety. In case the aircraft is at an altitude of 11,900 m and something happens to the engine, pilots will have more time to troubleshoot and contact the operating center before an emergency landing.

Most modern aircraft have very good incident response systems. People often think that when the engine is broken, the plane will free fall. But the truth is not so. The plane will hover forward.

Air turbulence due to terrain will not impact the aircraft if it reaches a safe altitude.

With each drop, the aircraft will hover 16-17 m to the front. Thus, from the time of engine failure at an altitude of 10,000 m until landing, the aircraft can go another 160 km.

This allows the pilot to fly the aircraft to the nearest airport for an emergency landing. Thus, flying higher will help the aircraft save, safer and faster.

Besides, flying at an altitude of 10 km above sea level will prevent the aircraft from hitting birds in the sky. Civil aircraft models can reach speeds over 900 km / h. Striking a bird could be equivalent to hitting a flying bullet at 1,220 km / h.

Apple devices achieves the highest customer satisfaction score

No product line is enough to beat Mac and iPad in terms of customer satisfaction in the PC and tablet market in 2019.

That is the result of the new data published today by the American Customer Satisfaction Index (ACSI).

In the Household Appliance and Electronics Report 2019 (Apple and electronics reports), Apple scored 83 ACSI, which is on par with it achieved in 2018. Apple’s overall satisfaction score is higher than Samsung scores (81 points), Amazon (79 points), HP (78 points), Acer (77 points) and others you can see in the table below:

According to the ACSI report: “According to the overall industry ranking, Apple ranked first for the second consecutive year with a stable and fairly high score of 83, and its customers so far have had expectations. Despite dropping 1%, Samsung still holds the 2nd position and is no longer in harmony with Amazon, which has dropped to 3rd. Amazon dropped 4% to 79, only 1 point higher than the industry average. Of the top three, Apple shows superiority in all aspects of the customer experience, but still lags behind Samsung and Amazon in value. ”

ACSI says that Samsung is the industry leader when it comes to the desktop segment, with Apple in second place, but Apple devices win in the laptop and tablet segments, resulting in a high overall score. Best for this brand.

Like last year, Apple achieved the highest rankings for everything from device design, to existing features and applications.

In terms of overall customer satisfaction, desktop PCs, notebooks and tablets still lag behind overall smartphone satisfaction, but among the larger devices, desktop computers have the highest level of customer satisfaction. .

It is known that in order to create a scoring system and give scores for such devices, ACSI used data from interviews with approximately 300,000 customers, thereby analyzing customer satisfaction for hundreds of companies in dozens of different industries.

Many restaurants in China are using serving robots (Part 1)

Serving robots have become an attractive option for restaurants in China as recruitment of waiters has become increasingly difficult.

Two years ago, Bao Xiangyi dropped out of school and waited in a restaurant for half a year to support himself, and the 19-year-old recalled that time in a difficult and obsessive way.

“It’s crazy to work in a number of Chinese restaurants. The number of my daily steps WeChat measured reached 20,000 steps in just one day, just taking food inside the restaurant alone.” , Bao said.

And this made him quit the waiter job and decided to go back to school, he is now a university in Hangzhou, Zhejiang province.

Serving robots developed by Pudu Tech, a startup in Shenzhen, have been adopted by thousands of restaurants in China, as well as several other countries including Singapore, South Korea and Germany.

“I cannot accept that 365 days a year would be like that,” Bao said. “Those days were filled with darkness and I felt like my whole life would forever be a lowly and mediocre servant.”

Olivia Niu, a 23-year-old Hong Kong resident, is also a good example. She quit the waitress job right after the first day of work. “During the peak hours, the work will be very busy, even though I am very hungry, but I still have to try to prepare meals for customers,” Niu said.

The service robot was developed by Pudu Tech, a three-year startup in Shenzhen

Becoming a waiter has never been a top career choice but it is still a great source of employment in China. Yang Chunyan, a waitress at Lanlifang Hotel in Wenzhou, southeast China, had two children and said she chose this job because she needed to make a living.

The young generation of China today has a bigger vision and understands more of the field. Among those born after 2000, 24.5% wanted a career related to literature and the arts. Next is education and IT industry in second and third place, according to aggregated information from Tencent QQ and China Youth Daily.

This makes it difficult for Chinese executives to recruit qualified staff, and even if so, very few people can withstand the daily pressure of hundreds of food orders. , so the best option is probably robots.

Impressive technology applications in sports at CES 2018

Assistive technology applications in the field of sports made a strong impression at CES 2018. Let’s take a look at some interesting inventions at CES 2018.

World boxing champion Floyd Mayweather has just launched a boxing training system based on VR technology. Using this system you can battle with boxing champion who has never lost.

James Williams, CEO of Mayweather Boxing plus Fitness, said: “Through every stage, you will learn how Floyd Mayweather defeats his rivals.”

There are also reflex training systems for athletes, helping athletes measure and practice their reflex speed.

“All major sports teams in the world use systems like this,” said Bob Bouw, sales representative of the Fitlight reflex system.

Meanwhile, a foldable electronic display system is used to measure hand-eye coordination, peripheral vision and many other reflex functions. This system serves the purpose of detecting whether athletes are experiencing a concussion.

Regular testing has also been scientifically proven to improve coordination smoothly – an indication that technology is strengthening for both the mental and physical aspects of sport.

There have been some interesting inventions introduced at the world’s largest consumer electronics exhibition (CES) 2018 in Las Vegas, USA.

Pouring wine without opening the bottle

Pouring wine without opening a bottle – what seems like only in this magic is true with Coravin special equipment. By piercing the cork with a tiny needle, users can pour out the wine while keeping the lid closed. As a result, the taste of expensive wines will be preserved, and the bottle can be kept in the cellar for a long time. However, the price of this product is also quite expensive, up to 999USD.

The TV can be rolled up

Flat-screen TVs, curved-screen TVs, and now even scrollable TVs. LG 65 “OLED TV, using flexible screen technology, when not in use can be rolled into the box to save space. So you can easily carry this TV to Wherever you want, users can use only part of the screen for a variety of purposes, such as checking the weather or adjusting music.

Virtual headset

Listen to music while working, without wearing headphones, nor does it affect anyone – office workers’ dreams will come true with the smart device of an Israeli startup.

The system, called Noveto, can track faces and shape the position of the ears, and then transmit the sound straight there. This type of virtual headset promises to be widely used in cars or entertainment centers.

Advanced technologies are applied in sports (Part 2)

Shoes and balls with electronic chips

Attaching chips to shoes and balls has now become relatively common. Initially the technology paid little attention, but in late 2011, Adidas in one of its advertising campaigns gave famous player Messi the use of these “smart shoes“.

In addition to using the best materials (super light, super durable), the design best suited to each player’s condition, it also has an electronic chip under the shoe.

This chip is capable of collecting all data during the match to know how Messi played in 90 minutes: how many kilometers run, the highest speed, the average speed, power, etc. so that can give diet, training appropriate for Messi in particular and other football stars in general.

Swimwear speeds up

FINA’s Federation Internationale de Natation has approved athletes who use swimwear to reduce water resistance from the 2000 Olympic Trials.

Until the 2008 Olympics, Speedo’s LZR Racer swimwear went above all to become the most popular swimwear for swimmers. Since Speedo LZR Racer sets, strange numbers have been recorded on the green track.

Only in 2008, there were more than 40 new records on the established swimming lanes, this number was even double what the swimmers did during the 30 years before 2008. Of course. setting new records can also be set due to many other objective factors such as diet, exercise, mood etc.

Many legendary swimmers have broken many records when wearing this special swimsuit

But a series of set records also partly demonstrate that this particular swimsuit will help many athletes reach their destination a few hundred seconds earlier, which is more than enough for sports. Competitive on time like swimming.

Chip

Position mounted on shoes

Since then, the installation of electronic chips into balls and competition shoes has also been formed. The chip attached to the outside ball to measure the parameters, also intended to combine with the hawk eye system, determine whether the goals of the players are valid or not.

Advanced technologies that are applied in sports (Part 1)

People are constantly looking for ways to break records in any area. Therefore, technology always goes hand in hand with sports to create breakthroughs.

Hawk eye system

In 1999, Roke Manor Research Company developed this system. The project was led by Dr. Paul Hawkins (he took his name to name the system) and was sponsored by British television company “The Television Corporation”.

In tennis, this system was first used by Jamea Jackson in the 2006 Master ATP tournament held at Key Biscayne. Today, in high-level tennis matches, in football matches, the speed of the ball is very fast, so it really needs a “hawk eye” system.

On the other hand, the common characteristic of both subjects is to determine the position between the ball and the line to determine the winner. Considering tennis alone, the ball is over the designated line as if the batter lost the score. In football, this system is effective to avoid “ghost goals” (the ball has not crossed the lime line to count as a goal).

The hawk eye system is increasingly widely used in many sports. Although it is controversial when many fans think that the human game will go if all the results of the competition are decided by machines. In particular, in the king sport is football, sometimes the referee’s mistake is an unexpected “attractive” factor.

Spray paint spraying penalty kick

Thanks to the paint lines sprayed from the sprayer of the referee, the free kick phase is made faster and less unnecessary controversy. Behind the success of this “new technology” is Heine Allemagne.

He is 44 years old, living in the state of Minas Gerais (Brazil), inventing “painted lines” for him merely for the purpose of helping the referee work more smoothly and accurately.

Always in the mind of the idea of ​​creating a special foam to help the referee since 2000, after the self-exploration process, Allemagne invented a white foam made from vegetable oil capable of self Decompose after 1 to 2 minutes. Through testing at domestic playgrounds in Brazil, the most successful success of this invention was at the 2014 World Cup.
