This Seoul bridge seems ordinary, but stars one of South Korea’s biggest problems: suicides

by

South Korea is a country that advances by leaps and bounds in technological question. It is home to some of the most important companies in the world -Samsung or Hyundai- and He is fighting To become one of the referents in the chips segment. Seoul, its capital, is a look at what could be the future of cities hypertecnologicalbut after that image of modernity, an increasingly silent pandemic is hidden: that of suicide. And no place better reflects this crisis than the Mapo bridge in Seoul, nicknamed ‘The Suicides Bridge’. Alarming figures. Suicide is a taboo issue in many societies that sometimes have not paid attention to avoid the tragic outcome. It is not something that Pille so far. In 2020, in Spain it committed suicide One person every two and a half and a half. Each country Try to deal with your way With this situation, but the case of South Korea is bleak. Do not go to the archives to see the evolution of suicides in the Asian country: In 2021, 13,352 people committed suicide. In 2022, approximately 13,000 were given. In 2023, the figure rose to 13,770. In the first six months of 2024, 6,375 people committed suicide, assuming a increase of more than 10% compared to the same period of the previous year. He total It was 14,439 dead. Cocktail. They are figures distant to the maximum of 2013, when 14,427 occurred, but in 2020, the country had the highest rate among OECD countries with 24.1 suicides per 100,000 inhabitants. It is more than double the average. The reason is that there is a social and cultural cocktail that pushes thousands of people to end their lives. There is one very high social pressure and competitiveness for being the best in studies and work life. If you do not achieve it, economic problems occur, but although that ‘success’ is achieved, there is a high level of stress and low social awareness about mental illnesses. Also idealized and impossible beauty canons for much of the population. And it is not something that cares only to suicide, since the scarce birth that is taking the country to an unsustainable situation is also the gross of those social pressures. THE MAPO BRIDGE Effect called. The most affected group is the one between ages of 10 to 39 and is the major Cause of death among South Koreans between 10 and 39 years. Between 40 and 56% of deaths in these age groups is due to suicide. These brutal pressures even affect celebrities of the country, so much that studies have already been carried out that relate the increase in suicides with the moment in which one of these celebrities ends with his life. As if there were an effect called or idealization of the act, three of the eleven cases of suicides between celebrities resulted in an increase in the rate among the population, leading people to use the same methods as said celebrity. In recent years, there have been numerous cases among young Astros of K-Pop, cinema and television, very exposed to criticism in a country where there is a very strict moral standard that these celebrities must meet. The notice says: “Line Life. Methods. They have gone changing These last years. At the beginning of the century, most used pesticides to get intoxicated. This poisoning remains one of the most used methods, but now it is through burning YoTan: Carbon cylinders that produce poisoning by carbon monoxide aspiration. The hanging has also become common (with examples such as’Sulli‘That they expose that effect called), but throwing themselves to train tracks or from bridges is also a method. THE MAPO BRIDGE. And all this leads us to the Seoul bridge. We have talked about Many bridges in Xataka And Mapo’s is, structurally, a normal bridge, almost ordinary. It does not stand out for design, certainly, but it has become the sad secondary protagonist of dozens of suicides in recent decades. It is not the only one from which the South Koreans throw themselves to end their lives, but one of the most used due to the current of the river has very difficult the rescue work very difficult. So much is the impact of the bridge on the statistics of the country that began to call colloquially as ‘The Suicides Bridge’. From the city, this was wanted to combat the structure as ‘bridge of life’ as part of a Samsung Life Insurance initiative. But it was not a simple name change. Measures. The company placed photos of happy families, among other measures to deter suicides, such as movement sensors that activated light posters with mood phrases, but they were considered a failure In 2015 and that was when the focus was changed to prevent suicide instead of deter. Thus, a series of active and passive measures were installed to stop the high rate of vacuum throwing, such as phones from which to request help every few meters (it has a length of about 1,300 meters), mirrors so that those who plan to jump see their face, cameras, high barriers and rollers that make it difficult to get to the edge. The fences are high and in the last upper section there is a roller We can see the roller, as well as the mirrors Social strategies. It is, in short, a series of actions to make jumping more difficult, but beyond this (which is still a patch), in recent years the country has taken the mental health of citizens more seriously. For example, strategies to prevent suicide thanks to greater media coverage than public awareness, as well as training campaigns and notions of suicide prevention for teachers and social workers. Also reviews focused on adolescents and another series of infrastructure measures to strengthen security on bridges and train tracks. Despite the efforts to reduce the incidence of suicide, the Mapo bridge remains a symbol of this crisis, with 846 people jumping From the bridge between 2014 and 2018, … Read more

The secret for a healthier chocolate is in prebiotics and probiotics. And now we know the “recipe”

by

The effect of chocolate on our health is ambiguous. Although some of these preparations based on the fruit of cocoa can report benefits for our health, the usual thing is usually that the sugar and other additions end up deriving in a final product far from being classified as “healthy”. Chocolate, healthier. Now, a group of researchers works on the development of a chocolate with additives that make it healthier. For this they have resorted to add prebiotic and probiotic ingredients in their recipe. Prebiotics + probiotics. Pre- and probiotics are two types of foods that help Regulate our intestinal microbioma. The difference between them is how they do it. Prebiotics are foods that provide nutrients to this microbiome. While probiotics are foods that provide us with microbiota, that is, they contain organisms such as bacteria that help us develop our digestive functions more effectively. The proposal of this team of researchers is to add prebiotic and probiotic ingredients to chocolate. Until now, the idea of ​​adding these elements to chocolate had already been investigated, but doing so had become a somewhat “laborious” task, those responsible for the new study explain. To avoid this complication, the team decided to resort to prebiotics that required a minimum processing such as corn and honey. Five formulas. The team combined the ingredients in different ways to obtain five formulas to compare. The first, reference, contained the usual ingredients in chocolate (such as cocoa butter, powdered cocoa and powdered milk). The rest contained prebiotics (corn and honey); a prebiotic (which could be Lactobacillus Acidophilus LA-14, o Lactobacillus rhamnosus Gg), and an additive to give flavor (which would be cinnamon or orange). Keeping sensations. One of the factors that the equipment wanted to put to the test were the fat levels of these products since the texture of the resulting product depends on these. They found that the formulas maintained this characteristic consistently but also pointed out some differences between conventional chocolate and sinbiotics (those that were subject to the study). For example They observed They added orange showed a lower pH (greater acidity), greater humidity and higher protein levels compared to the rest. They also observed that the four symbiotic chocolates presented higher levels of antioxidants. These lost some consistency, which made them less crispy. Counting microbes. The study also included an analysis of the survival capacity of the bacteria used. They found that these continued to maintain their vitality after 125 days of chocolate storage. The team also submitted these to “stomach conditions” and found that microbes were also able to survive these conditions for more than five hours. The details of the study were published In an article In the magazine ACS Food Science & Technology. The benefits (and risks) of chocolate. The effects, positive and negative, of chocolate can be associated with certain compounds, some present in their main ingredient and others in additives. One of the key elements is antioxidants. Antioxidants are especially in black chocolate, and among them Epicatechina stands outa type of flavonol. These compounds can protect us from free radicals, which has been associated with better cardiac health, a “balanced” immune system, a lower risk of diabetes, and other potential benefits. On the other hand, the sugars and fats present in chocolates can be made harmful if we consume excessive amounts, especially if we consume is not dark chocolate but more sweetened versions of the product.

In their search to make the increasingly productive olive trees, these researchers have had an idea: to throw coal

by

The jungle floor is between reddish or yellowish; He is sterile and ungrateful, blinding and distemper. It is plagued with mineral oxides or empty of calcareous materials. It is and has always been a bad ground. Therefore, when in the middle of the Amazon, the settlers met the ‘Terra Petra‘They couldn’t believe it. It was a black, tremendously fertile land, incredibly resistant to the decomposition of organic matter. For decades, nobody knew where he had been able to leave. A dark enigma for a bright future. Some said that the Andes volcanoes could have come, others suggested that they should be a product of sedimentation of the tertiary lakes. But, When analyzing they realized that they were truffled with ceramic remains, fish swords, jewelry and human objects. The miracle of the ‘Terra Preta’ was the miracle of huge agricultural communities mixing land, vegetable coal, organic material of all kinds and favoring the growth of an own ecosystem within them. Charcoal? Indeed. That same face The researchers stayed. The jungle peoples often use a burning system to create fertile soils. The problem is that they lose fertility quickly. With the ‘Terra Preta’ it does not happen and the secret is in that coal. What in jargon is known as ‘biochar’. And that is really working? That is what The European Soil O-Live project has been askedif the olive trees could treat with a mixture of biochar and compost. The result is what brings us here: what Yes it works. According to researchers at the University of Jaén, coal treatment increases oil production between 7 and 24%. That is, between 0.4 and 1.7 kilos of oil per olive tree. It is true that it is a preliminary investigation, but without a very promising place. And what do we want it for? That is, without this type of “treatments” Spain is already the place of the world where more oil occurs and not for: grows 15% per year. The problem is that the machine cannot stop because demand It grows even more. Where will this race take us, that voracity? That is one of the great questions of the century.

It is one of the most chilling horror films in recent years, almost nobody has seen it and you have it in prime video

by

There are countless horror cinema subgenres, as of any other variant of the fantastic. There are more trotted and frantic films, there are those that are betting on a more murky and rested atmosphere. There are films that derive from previous successes, others that dare to go into unpleling territory. Not all are for all tastes, and clearly ‘Ritual from beyond‘(Depressant Spanish title for the much more lyrical’ to Dark Song ‘), than You can see in Prime Videoit is of that last species. ‘Ritual of the beyond’ has a rhythm and development that will not possibly interest all fans. But if the occult, dark atmospheres, low intensity horror and uncommon messages interest you, ‘ritual of beyond’ is for you. He writes and directs Liam Gavin, who has not signed anything else apart from a couple of chapters of ‘The curse of Bly Manor’ in Netflix In ‘Ritual from beyond’ we will meet a woman who rent a house isolated from everything. His only company in an increasingly suffocating and strange series of days will be a occultist who must help her make a long, dangerous and strenuous ritual to be able to contact her deceased son. But both have secrets that can endanger the purpose of that isolation. It is a classic plot structure (a couple of characters locked in a space that will oppress them more and more until they put their integrity and sanity at risk) that, however, takes a series of unexpected paths. With a meticulous and almost documentary description of the ritual that awaits boththe film builds an atmosphere of threat and an increasingly demential rhythm that turns this film into a hidden jewel of the genre. That everyone will not like, without a doubt, but that will obsess those who connect with their brave proposal. In Xataka | In 2024 Nicolas Cage, in 2025 Stephen King.

The Spanish invention that already interests in the industry

by

We have been doing decades Combustion engines more efficient, but always with the same basic principles. Now, a Spanish startup has a radically different idea: an engine designed from scratch for hybrids of the future. It is called E-Rex and has captured the attention of two giants: Renault and Geely. And the tests will begin to see if the fiance “Spanish revolutionary engine” becomes the heart of the new electrified cars. The e-rex. Juan Garrido Requena He is an engineer and co -founder of Innengine. In 2020, a video With a striking holder. “E-Rex: The real engine for extended range.” In it, he told us about his vision for the creation of a combustion engine that would revolutionize hybrid mobility. Such an engine should be compact, light, that did not have vibrations or emit a remarkable noise and, in addition, that it was efficient. His e-rex He met these conditions and claimed that he was the first designed specifically for the cars of the future, since the hybrid motors then, and now, were modifications of traditional combustion motors. Like a 2,000 cc of gasoline. The key of the e-rex is not only its size and weight of about 35 kilos, but the power. It is an engine of a time that, according to Garrido, is twice more powerful than one two -stroke and four times more powerful than one four -stroke. The consumption is low, also the emissions of CO₂ and NOX and is comparable in potential at a four times of 2,000 cc. Its confrontated piston design and a variable compression relationship system is what makes it possible to adapt to different needs (power or efficiency) and what eliminates vibrations, since the strength of the pistons is compensated naturally. Extended autonomy hybrids. This engine is not designed, apparently, to retire the current combustion engines, since Juan Garrido refers to its creation as what the future of something more concrete will define: extended range vehicles. These are like a hybrid, but vice versa: instead of having a main combustion engine with the support of an electric motor, the electric motor is the main and the combustion is to feed a generator, which is the one that gives energy to the electric to move the wheels. In summary accounts: the combustion engine becomes the ‘pile’ of the electric motor, which also has a battery of which to ‘throw’. It is an electric in theory, but a hybrid in practice. Horse enters the equation. These Extended range vehicles They were not the most popular hybrids five years ago. Nor are they now, but things can change because a giant has entered the room. Horse is one Joint Venturewhich becomes a company created by two or larger companies that join forces to achieve a common goal. Like the loss in combat NorthvoltOh. In this case, those two large are Renault (45%), Geely (another 45%) and Aramco (the remaining 10%). Among the company’s objectives, is the development of new hybrid engines, batteries and other elements for that vehicle of the future. They have plants in various parts of the world, being Spain one of them and cradle of the engine of Renault Rafale E-Tech HybridFor example. Above, a conventional engine. Below, the e-rex. They claim that it is 40% cheaper to manufacture without the need for new techniques or materials Evidence. In that search to get new generation engines, Horse began this year to produce New 49 kW engines that are capable of feeding hybrid cars at speeds of 130 km/h, but the next steps point to the E-Rex’s e-rex. In a releaseboth companies have confirmed an agreement to prove two of the E-Rex prototypes. These tests will be carried out in the Laboratory of the Department of Clean and Thermofluid Mobility of the Polytechnic University of Valencia and these results will be used to see if the Group licensed exclusively by the INNENFINE technology. If this occurs, the next step is to produce them in mass. Revolution. Julien Faure is Horse’s director of Technology and has commented that “revolutionary technology and architecture could completely change the dynamics of combustion technology with implications for automotive, navy, aviation, drones and energy generation.” Faure ensures that these tests “potentially are of historical importance.” For his part, Roberto Leandro, Executive Director of Innengine, says that collaboration is more than a milestone: “a bold step towards a more sustainable future.” It is clear that you have to be with an eye on this Spanish engine that, if it meets these tests, can be an important impulse for electrified cars while we are still waiting for solid state batteries.

Drought and mass tourism have aggravated the shortage of water in the Balearic Islands. Now it is going to entrust the desaliners

by

Throughout the month of March Let’s have a storm characterized by many rains. However, when this temporary pass will come the good weather and return The drought again. Given this situation, the Balearic Islands, one of the communities most affected by water scarcityThey are looking to get ahead. The projects. The seafore and water cycle. has announced The construction of three desalination plants in Mallorca, Menorca and Ibiza. The installation will have an initial budget of 3.5 million euros and are expected to be operational within five years, supplying more than 60,000 inhabitants. A serious problem. Currently, reservoirs on the islands are 51% of its capacity, showing the water problem despite the recent rains. For that reason, from the Ministry They have pointed out That these new desalination makers are to guarantee the medium and long term water supply, regardless of the weather conditions. However, this is not all, because there are other concerns, such as overexploitation of aquifers that It has generated problems With the introduction of salts. In addition, the archipelago receives a large amount of tourism every summer, which triggers demand and Test The supply capacity. Future desalination. The Balearic Government has planned the construction of desalists financed through the STI 24-25 call, with the aim of improving the water supply in the region. In Mallorca, the Rostent area will be prioritized, especially the strip between Ses Salines and Artà, as well as the municipalities of the PLA. In Menorca and Ibiza, areas with the highest water deficit will be served. The project will take place in several phases with the construction in 2027 and the commissioning of the facilities in 2030. But they already have others … that’s how, in the Balearic Islands There are desalination plants They help meet the growing demand for water. Currently, ABAQUA manages a supply and desalination infrastructure network that includes several plants, such as Mallorca, Menorca and Ibiza. To give an example, the three existing desalination plants in Ibiza operate at 75 % of their capacity throughout the year, and They reach 110 % peaks In more than five months, which shows the overload of the supply system. Inconveniences. Although desalination plants have become an alternative for water use, they have a series of problem. On the one hand, they need high energy consumption, so would imply an increase in the price of water In the long term. On the other hand, these facilities They can have brinea residue with high salt concentration that can damage marine ecosystems. So the Balearic Islands will have to continue trusting technologies such as desalination plants, which despite the aforementioned problems, offer a response to the growing demand for water. However, they can bet on the implementation of long -term measures such as Wastewater reuse or Other methods within desalination.

use any handless device

by

The technological world usually starts from the assumption that we can all use our hands, but more than 100 million people with reduced mobility are excluded from that equation. The Spanish startup Aurax has decided to solve this problem with Mouthx, an oral controller that allows anyone (has their reduced mobility or not) interact with mobiles, tablets and computers without using the hands. “In Aurax we have developed a hands -free, intraoral control device, consisting of two Joysticksone that acts with the jaw and another with the tongue. We also have Head Tracking For secondary controls, “explains Narcís Codina, founder of Aurax, during an interview at 4yfn Barcelona, ​​the entrepreneurship event starts from the MWC 2025. Mouthx’s origin is deeply personal. The project arose when Codina met Armando Folgado, who has pentaplejía due to a spinal cord injury. Armando, current partner of Aurax, became inspiration to develop this technology that wants to transform the lives of millions of people. Precision that exceeds current limitations What distinguishes Mouthx from other solutions, according to its creators, is Its precision and versatility. “We use a technology from Joysticks that measures the magnetic field. In the end the accuracy is 500 points on each axis, in a millimeter of radius. In the end we do not move the tongue or the jaw more than a millimeter, “says Codina. A Mouthx model exposed in the MWC 2025. Image: Xataka. This wireless oral controller is an integral solution for those who have had very limited options. “They (in reference to users with reduced mobility) cannot control a mobile, apart from the fact that it is only with the voice. And as a computer, they use tobii, which is like a Eye Trackerin the end is two axes, it is a mouse with one click. And you have to click twice to select the second button, “explains the founder. Tobii is an old acquaintance of XAtaka: The difference in Mouthx with respect to what is raised by teams such as Tobii is remarkable: while current solutions allow only a basic interaction, Mouthx offers total control. “We in the end have made a device that allows you the total control of a mobile and a computer. And in fact as we also emulate, we can be like a joystick, we can be up to a Gamepad“Narcís adds. The device works with three axes in each joystick, which allows three -dimensional precision. “It’s 3D, it’s not two axes and click,” says Codina. This technology makes it possible for users to perform precise movements with hardly any effort. Easy to use, quick to learn One of the pleasant surprises that the Aurax team has taken has been The speed with which users learn to use the device. “The learning curve of users so far, we put both the equipment and Beta Testers as Focus Groups That we have done, it goes between fifteen minutes and an hour that most to learn. That is, go through the learning curve and use a mobile and a computer in full, “says Codina. The device, similar to an invisible dental splint, is manufactured for each user by means of an oral scanner. This customization is an inevitable friction today, but guarantees comfort and precision, even allowing to speak normally while used. Although Mouthx was born thinking about people with functional diversity, The company has discovered that its technology has much broader applications of the initially planned. “We were surprised, there are people without mobility problems that interest more than we expected. In the end there are always uses that one can get him,” says the founder. “We are realizing that for a neurosurgeon it is like having two more hands. Or a pilot you can use Google Maps With your hands on the steering wheel and looking where you have to look. A chef, a musician, a creative, or an engineer who wants more control, “he says as more use cases. The power of the device is not only in its precision, but also in Its ability to execute multiple commands simultaneously. “There are many solutions that allow you several buttons, several commands, but not simultaneous, you have to click one or the other. We allow you three tongue axes, three axes in jaw and three axes in the head. And this is quite powerful,” he explains. For Gamersthis capacity represents a competitive advantage, according to the founder: “You with your jaw can have eight commands and with your tongue too.” Eight are also the hours that your battery lasts, rechargeable connecting Mouthx to your case. Mouthx is accompanied by a highly configurable application that allows total customization. “We have a very configurable app that allows the user to choose which devices that are matched at the same time,” Codina explains. Users can create different configurations according to their specific needs: “You have your settings for your computer, one in general for Office or one for a specific program, and one for … for whatever you want. Well, you can jump from each other directly from the device.” An imminent pilot and launch The Vall d’Hebron University Hospital in Barcelona He has started a pilot study to evaluate Mouthx’s usability in people with reduced mobility. Dr. Lluïsa Montesinos, head of the unit of core injured, expects the device to offer greater autonomy and independence to patients. A patient testing mouthx. Image: Vall d’Hebron University Hospital. The device will be available for presale from the end of March Through the Aurax website. “Now people can point like Beta Testerbut at the end of the month they can point, and make orders. Can buy through Pre-Orders With a 30% discount, that is, for 1,000 euros instead of 1,300, delivering to seven months seen, towards October, “says Codina. Initial marketing will be online, due to the personalized nature of the product: “As the device is personalized, both design and manufacturing now requires a buffer scannerany dentist can do it, the dentist who has a reference, because … Read more

We have been trying to decipher how 1950 the Antarctica would be like. We just discovered it

by

We have always seen the earth in the same way: Green and Brown Earth masses and the poles contrasting in white. Logical, because it has been tens of thousands of years covered by that white command, but the funny thing is that we have been trying to unravel What would Antarctica be like without ice. And we just discovered it in what is a curious and bleak view that could be the future of the earth. Decades melting Antarctica. Making Antarctica is not just a matter of curiosity. It is also key to predicting ice loss and sea level elevation. It is something that has studied Since 1950, but in 1996 the culminating moment came: the creation of the Bedmap consortium. With European support, many measurements and the most avant -garde technology at that time, the researchers marked the goal of creating a complete map of Antarctica. That came a few years later, with the Bedmap1 published in 2001. Bedmap1 Methods. It is what allowed us to know the average elevation of the rock base of Antarctica, the distribution of ice and its volume. Bedmap1 gave us a vision of that scenario with a resolution of five kilometers. In 2013 Bedmap2 appeared, for which they used ten times more measurements than the first and with a superior resolution. For the analysis, the researchers gathered data thanks to airplanes that fly over the area by sending radio pulses that allow measuring both the ice thickness and the most interesting: the depth of the rock bed. Crossing the data of these radars, batimetric data, satellite information and seismic studies, we can have that radiography of Antarctica. Bedman2 To the third is the defeated. And the most accurate so far is the one that crowns this article: Bedmap3. This is the result of the study of more than 82 million data points – some times more than those taken into account to elaborate Bedmap2 – and, as explained from British antarctic surveyit is as if they had removed the 27 million cubic kilometers of ice that cover the territory. In this new analysis, we see the most hidden places of the great mountains, but also details of the deepest cannons. Bedmap 2 already had a great level of detail, but this third map reveals is more depth in some areas. For example, where is the thickest layer of ice. It has been identified in an unnamed cannon in Wilkes, where the ice has a whopping 4,757 meters thick. Bedmap3 Fascinating. The resolution of this third attempt is 500 meters and, as we say, is the result of 70 years of measurements that have combined to give life to the new map. The three overlapping models It is what allows researchers to be more precise when having place statistics: Total ice volume in Antarcticaincluding ice platforms: 27.17 million km³. In Bedmap1, the calculation was 25.34 million km³. In Bedman2, 26.54 million km³. Total ice surface in Antarcticaincluding ice platforms: 13.63 million km² Ice thickness in Antarcticaincluding ice platforms: 1,948 m (excluding ice platforms: 2,148 m) Potential increase in sea level globally if all ice melts: 58 meters. And scary. That last value, the potential increase in sea level, is one of the main utilities of this type of research. It has not varied in the three attempts to map Antarctica and, as one of the researchers of the Bedmap project points out, the utility goes beyond the simple objective of satisfying curiosity. With the new data, Peter Fretwell comments that “it is evident that the Antarctic ice layer is thicker than we originally realized and has a greater volume of ice. It is also buried in a layer of rock located under sea level and is something that exposes ice at a greater risk of melting due to the incursion of warm water of the ocean.

Volkswagen believes that car screens are getting too far

by

For some car manufacturers, Only the screens matter. After the extreme minimalism of Tesla Model 3 2017 That eliminated buttons to relegate the control of the car to the huge central screen, there were manufacturers that got into the car. Filling the screw dashboard seemed like luxury at the wheel, but it is an idea that has not set Among users, critics and even the most relevant body in Europe to evaluate the safety of vehicles: EURO NCAP. Now, the brands are realized that they cannotPost everything to the screens And there are such strong statements as that of the Volkswagen design chief, who has recognized that “it is not a phone: it is a car.” Trend. Tesla is the perfect example when talking about cars screens. It is not the one that has the most, but that, in its last models, has relegated virtually all the functions of the car to that central console. Other brands like Mercedes soon got into the car with splashes in which the screens were protagonists and there are those who have taken this to the extreme, especially when we talk about electric car. Mazda 6e, the Electric Berlina And Mazda 3 It seems that talking about 100% implies putting aside the buttons. Even brands such as Mazda who have opted for small and touch screens only with the stopped vehicle have given a flying when they have presented the electric model. But perhaps one of the most exaggerated cases is Volkswagen. “Buttons”. In quotes. In the main image we have the dashboard of the Volkswagen ID. Every1the new 100% electric utility that wants to place itself as the electric car par excellence. The interior is futuristic, science fiction and yes, it has buttons. Real buttons, not like those of the Atlas, the new golf or the ID.4. THE FLYING OF ID.4 In these three models, The buttons are haptic, A kind of digital button that does not offer that pulsation feedback such as when we put pressure on a real button, but a vibration. How to type on a mobile phone, go. On the way, it may not be enough to give information to the driver when there are elements such as the vibration of the vehicle itself when rolling through a land that is not completely smooth. “It’s not a mobile”. This model has not yet went on sale, but the criticisms and the latest decisions of Euro Ncap seem that they have made the German firm rethink things. And he has done it. As we read in CoachAndreas Mindt, the brand design chief, has been the one who has taken the initiative by commenting that, from ID.2 that will arrive next year, all cars will have “physical buttons for the five most important functions.” These functions are volume, heating, fans control and emergency light. “They will be in every car that we do from now on, we have understood.” This reverse is curious, but well received because it is evident that they recognize that there is a real problem with this type of tactile interfaces and that do not use everything. “Never, we’ll never make this mistake again. In the steering wheel, we will have physical buttons. We will not have to guess more and have real feedback. People love that and, honestly, it is a car. Not a phone: it’s a car. ” Not a luxury. VW has not been the only one that, recently, has realized that touch screens as the only method of control of the car are a engoring for certain things and a potential risk for safety. The German Mercedes has also considered the screens a luxury symbol in its recent vehicles. The more, and bigger, the better. However, although the ‘Hyperscreen’ will not go anywhere, the design chief of the three -pointed brand admitted in a recent interview that they must devise another way to transfer that luxury to their vehicles, such as better finishes or more handmade pieces … instead of so much screen. With head. The truth is that, since the fever began by the car “Every screen”, each brand has made the war on its own. Lincoln, for example, It offers huge screensbut not tactile and only serve as a information viewer. Mazda (except in the 6e) continues to bet on buttons next to a screen of food dimensions; Peugeot, Renault or Toyota, among others, also incorporate large screens, but there are elements such as physical buttons in the steering wheel and to control the air conditioning that are maintained. Mindt rounded his comment on the future of the interfaces in Volkswagen stating that they will continue to offer touch screens “partly due to the new legal requirements that, as in the US, impose that all cars have a backward chamber. There are a lot of other functions that we can offer in certain areas and the screens will be large, but the five main things will always be in the form of physical button. That is very important. ” Therefore, whether by Euro NCAP warning or because they have realized that delegating all vehicle actions to haptic screens or buttons is not the most sensible, welcome that VW philosophy.
