schwit1 shares a report from The New York Times: As poor countries around the world struggle to beat back the coronavirus, they are unintentionally contributing to fresh explosions of illness and death from other diseases -- ones that are readily prevented by vaccines. This spring, after the World Health Organization and UNICEF warned that the pandemic could spread swiftly when children gathered for shots, many countries suspended their inoculation programs. Even in countries that tried to keep them going, cargo flights with vaccine supplies were halted by the pandemic and health workers diverted to fight it.

Now, diphtheria is appearing in Pakistan, Bangladesh and Nepal. Cholera is in South Sudan, Cameroon, Mozambique, Yemen and Bangladesh. A mutated strain of poliovirus has been reported in more than 30 countries. And measles is flaring around the globe, including in Bangladesh, Brazil, Cambodia, Central African Republic, Iraq, Kazakhstan, Nepal, Nigeria and Uzbekistan. Of 29 countries that have currently suspended measles campaigns because of the pandemic, 18 are reporting outbreaks. An additional 13 countries are considering postponement. According to the Measles and Rubella Initiative, 178 million people are at risk of missing measles shots in 2020. The risk now is "an epidemic in a few months' time that will kill more children than Covid," said Chibuzo Okonta, the president of Doctors Without Borders in West and Central Africa. As the pandemic lingers, the W.H.O. and other international public health groups are now urging countries to carefully resume vaccination while contending with the coronavirus.

America's Air Force "is hoping to pit an autonomous drone equipped with an artificial intelligence-driven flight control system against a fighter jet with a human pilot in a little over a year," reports The Drive: [T]he general concept of a fully-autonomous unmanned combat air vehicle (UCAV) capable of air-to-air combat, as well as air-to-ground strikes, hold great potential to fundamentally change the character of aerial warfare... At its most basic, a UCAV would be able to perform many of the same functions as manned aircraft, but would be able to make key decisions faster and more accurately, taking into account much more information in a shorter period of time, without any concern about being distracted or confused by the general chaos of combat. They can also be networked into swarms that work cooperatively to maximize their combat effectiveness at any given time far beyond what a human-piloted formation could.
The head of Air Force's Joint Artificial Intelligence Center "implied that the scheduled faceoff was very much an aspirational goal," according to the article, "and that it wasn't clear if it would happen as planned."

They also remember when Elon Musk responded to a tweet suggesting there should be a competitor to the Air Force's F-35 program. "The competitor should be a drone fighter plane that's remote controlled by a human," Musk wrote, "but with its maneuvers augmented by autonomy. The F-35 would have no chance against it."

"This spring, America took an involuntary crash course in remote learning," writes the Wall Street Journal, noting it affected 50 million students from kindergarten through 12th grade.

"With the school year now winding down, the grades from students, teachers, parents and administrators is already in: It was a failure..." The problems began piling up almost immediately... Soon many districts weren't requiring students to do any work at all, increasing the risk that millions of students would have big gaps in their learning... Preliminary research suggests students nationwide will return to school in the fall with roughly 70% of learning gains in reading relative to a typical school year, and less than 50% in math, according to projections by NWEA, an Oregon-based nonprofit that provides research to help educators tailor instruction. It expects a greater learning loss for minority and low-income children who have less access to technology, and for families more affected by the economic downturn.... About 9.7 million students aren't connected to the internet, according to an estimate by the EducationSuperHighway, a nonprofit focused on connectivity in public schools. [The national average for unconnected students is 20%] "As a nation, we were not prepared to take learning online," said founder and CEO Evan Marwell...

School districts didn't realize the number of students without access to devices and the internet until they surveyed parents. Districts that could afford to do so hurried to buy the technology needed to get students online. Some, such as those in Austin and Belleville, Illinois, put Wi-Fi wired buses in parking lots for students to connect from their parents' cars. Many districts prepared printed packets of work for students without online access, which were handed out in food drive-through lines at schools....

Remote learning has turned the simple task of taking attendance into a challenge. Many count students as present if they log in to do work in programs like Google Classroom, an online classroom manager. Some give attendance credit for weekly progress on completed work, while others allow parents to call in to vouch for their children. Some districts aren't bothering with attendance at all. Those that have been able to track attendance say it has been below regular levels. Some students have simply gone missing. Early into the shutdown, the Los Angeles Unified School District estimated that on any given day in a week span, 32% of high-school students didn't log in to learn.

Dyson has revealed new photos and information about their failed electric SUV, which the company canceled last October due to high costs. The Verge reports: In a new blog post on his company's website, Dyson shows off some of the first images and videos of the real prototype it made before the project was killed last October, as well as a few more computer renderings. He describes the SUV as "a radical car which was loaded with technology," and says his company "solved lots of problems that are traditionally associated with electric vehicles," though the project was ultimately abandoned for not being "commercially viable." Missing from the post is any substantive explanation of what those problems were, though, or how the company was going to solve them. Dyson touts a "spoke, integrated and highly efficient Electric Drive Unit (EDU) comprising Dyson digital electric motor, single speed transmission and state of the art power inverter," though there's no explanation about what sets those technologies apart from the ones developed by other companies in the electric vehicle space.

Other listed design benefits (like a flexible battery pack design, improved interior space, longer wheelbase) and features (like a heads-up display or handle-free doors) are also far from unique. And while Autocar reports that the SUV was supposed to offer somewhere around 600 miles of range using a 150kWh battery, Dyson never got close enough to put that claim to the test. One of the few standout parts of the SUV is the steering wheel, which looks more like a video game controller than anything.

sciencehabit writes: Roughly half of the "normal" matter in the universe -- the stuff that makes up stars, planets, and even us -- exists as mere wisps of material floating in intergalactic space, according to cosmologists. But astronomers had no good way to confirm that, until now. A new study has used fast radio bursts (FRBs) -- powerful millisecondslong pulses of radio waves coming from distant galaxies -- to weigh intergalactic matter, and the results match up with predictions. "Using FRBs as a probe has been an exciting prospect for a while," says astronomer Paul Scholz of the University of Toronto, who was not involved with the work. "Now that we've built up a sample of local FRBs, we're starting to be able to do this. It's certainly exciting." Over the past few decades, cosmologists have compiled an inventory of the stuff that makes up the universe. Some 68% is dark energy, a mysterious force accelerating the universe's expansion. Another 27% is clumps of dark matter that hold galaxies together. Just 5% is so-called normal matter.

Cosmologists know how much normal matter there should be; they can calculate it from how much the big bang should have produced and from the microwave ripple of this cosmic event that still echoes through space. But they can only see about half of it glowing as galaxies and dense gas clouds. The rest, a rarified, intergalactic gas of just one or two atoms in the volume of a typical office room, has been almost impossible to detect. That was until the first FRB burst on the scene in 2007. Because these sporadic blasts are so bright and short, FRBs were originally thought to come from an instrumental glitch, or a source on Earth. (Some early "FRBs" were found to come from a microwave oven at an observatory.) But as detections of FRBs piled up, astronomers realized they were coming from distant corners of the universe. Pinpointing them was difficult because of their rarity: Observers had to be pointing in the exact right direction to catch one, and they wouldn't have time to focus other scopes on the source. These days, telescopes that view large portions of the sky continuously are bagging more FRBs.

An anonymous reader quotes a report from The Wall Street Journal, written by James Nestor: Breathing is a missing pillar of health, and our attention to it is long overdue. Most of us misunderstand breathing. We see it as passive, something that we just do. Breathe, live; stop breathing, die. But breathing is not that simple and binary. How we breathe matters, too. Inside the breath you just took, there are more molecules of air than there are grains of sand on all the world's beaches. We each inhale and exhale some 30 pounds of these molecules every day -- far more than we eat or drink. The way that we take in that air and expel it is as important as what we eat, how much we exercise and the genes we've inherited. This idea may sound nuts, I realize. It certainly sounded that way to me when I first heard it several years ago while interviewing neurologists, rhinologists and pulmonologists at Stanford, Harvard and other institutions. What they'd found is that breathing habits were directly related to physical and mental health.

Today, doctors who study breathing say that the vast majority of Americans do it inadequately. [...] But it's not all bad news. Unlike problems with other parts of the body, such as the liver or kidneys, we can improve the airways in our too-small mouths and reverse the entropy in our lungs at any age. We can do this by breathing properly. [...] [T]he first step in healthy breathing: extending breaths to make them a little deeper, a little longer. Try it. For the next several minutes, inhale gently through your nose to a count of about five and then exhale, again through your nose, at the same rate or a little more slowly if you can. This works out to about six breaths a minute. When we breathe like this we can better protect the lungs from irritation and infection while boosting circulation to the brain and body. Stress on the heart relaxes; the respiratory and nervous systems enter a state of coherence where everything functions at peak efficiency. Just a few minutes of inhaling and exhaling at this pace can drop blood pressure by 10, even 15 points. [...] [T]he second step in healthy breathing: Breathe through your nose. Nasal breathing not only helps with snoring and some mild cases of sleep apnea, it also can allow us to absorb around 18% more oxygen than breathing through our mouths. It reduces the risk of dental cavities and respiratory problems and likely boosts sexual performance. The list goes on.

Yes, economist Tyler Cowen and former world chess champion Garry Kasparov (now the chairman of the nonprofit Renew Democracy Initiative) co-authored an opinion piece this week arguing that Covid-19 "is illustrating that some aspects of a Universal Basic Income may be more necessary and more workable than previously thought. But there is one big piece missing: The economic output required to pay for such policies."

Their suggestion is to boost "abilities to succeed with major projects" and "to invest ambitiously in innovation." And TechCrunch recently hinted at one very specific suggestion. "If policymakers want to do more than just keep the floor from falling out and start laying the groundwork for an actual recovery, then they ought to be discussing a different UBI as well: Universal Basic Internet." The government has delegated providing access to internet to the private sector for far too long. Only the "more prosperous" have been able to enjoy the full benefits of high-speed internet...

[T]he math makes clear that closing the digital divide will generate a digital dividend. There's no easy to way to measure the impact of broadband access on the economy, but several studies indicate that this is exactly the sort of investment we should make in a time of crisis: some have estimated that doubling broadband speeds adds around 0.3% to GDP growth; others forecast that every broadband-related job generates between 2.5 and 4.0 additional jobs; and, yet another study determined that a 10 percentage point increase in broadband access could increase GDP per capita by $13,036. Simply put, there's a high ROI — return on internet — associated with increasing broadband access.
The article points out that somewhere between 23% and 28% of Americans currently don't have broadband internet access. And it also suggests "trainers to increase digital literacy around the nation.

"This approach to closing the digital divide will go a long way in helping the nation recover from the COVID collapse."

The Food and Drug Administration is cautioning the public about the reliability of a widely used rapid test for the coronavirus. The test, made by Abbott Laboratories, has been linked with inaccurate results that could falsely reassure patients that they are not infected with the virus. From a report: The Trump administration has promoted the test as a key factor in controlling the epidemic in the U.S., and it's used for daily testing at the White House. As first reported on NPR, as many as 15 to 20 out of every 100 tests may produce falsely negative results. A study released this week indicated that the test could be missing as many as 48% of infections. The FDA issued the alert on the Abbott test "in the spirit of transparency." In a press release, the agency said it's investigating whether the false-negative results could be connected to the type of swab used in the test or the material the samples are stored in for transport. It also cautions that "any negative test results that are not consistent with a patient's clinical signs and symptoms or necessary for patient management should be confirmed with another test."

LinkedIn is using AI and machine learning to generate screening questions for active job postings. From a report: In a paper [PDF] published this week on the preprint server Arxiv.org, coauthors describe Job2Questions, a model deployed that helps recruiters quickly find applicants by reducing the need for manual screening. This isn't just theoretical research -- Job2Questions was briefly tested across millions of jobs by hiring managers and candidates on LinkedIn's platform. The timing of Job2Questions' deployment is fortuitous. Screening is a necessary evil -- a LinkedIn study found that roughly 70% of manual phone screenings uncover missing basic applicant qualifications. But as the pandemic increasingly impacts traditional hiring processes, companies are adopting alternatives, with some showing a willingness to pilot AI and machine learning tools. Job2Questions is designed to reduce the time recruiters spend asking questions they should already have answers or exposes gaps candidates themselves can fill.

schwit1 shares a report from Quartz: A group of volunteers in China who worked to prevent digital records of the coronavirus outbreak from being scrubbed by censors are now targets of a crackdown. Cai Wei, a Beijing-based man who participated in one such project on GitHub, the software development website, was arrested together with his girlfriend by Beijing police on April 19. The couple were accused of "picking quarrels and provoking trouble," a commonly used charge against dissidents in China, according to Chen Kun, the brother of Chen Mei, another volunteer involved with the project. Chen Mei has been missing since that same day. On April 24, the couple's families received a police notice that informed them of the charge, and said the two have been put under "residential surveillance at a designated place." There is still no information about Chen Mei, said his brother. It is unclear whether the arrest of the couple and the disappearance of Chen are directly linked to their GitHub project, named "Terminus2049."

Chinese citizens had been turning to Microsoft-owned GitHub after the outbreak began, as it remains one of the few major foreign websites that can still be accessed in China. Now, volunteers linked to these GitHub pages are facing the growing risk of reprisals from authorities. Another GitHub page, #2020 nCov memory, which was initiated by seven volunteers around the world to chronicle personal accounts and news stories of the outbreak, is no longer publicly available. The team behind #2020 nCov memory said in an email to Quartz that they will suspend operation of the page and collection of submissions due to the "situation" in China, and that they hope to see "sunshine tomorrow."

Two lead economists for the World Bank called for an updated online version of a legendary government program from America's Great Depression during the 1930s -- public works programs -- as a companion to widespread calls for quarantining: What is missing in such mandatory "stick" approaches is the more active use of "carrot" incentives that could both encourage self-isolation and help prepare a workforce to bounce back in the recovery phase.... [W]e propose that governments subsidize a set of activities that could be done from home. This would further induce self-isolation, reduce the need for quarantine enforcement, and encourage some to learn new skills that could be useful after the pandemic is over.

It could also provide effective, self-targeted social assistance to young people who have lost their jobs due to quarantines and lockdowns. Several categories of activities satisfy these criteria: data labeling, document digitization, and virtual services.
Long-time Slashdot reader sixoh1 quips it could be a kind of "Mechanical Turk for all," but adds, "One idea that struck me was converting documents to display online."

The two World Bank economists also suggest that governments subsidize online courses -- and maybe even streaming services. In these times of social distancing, "There is actually a public-good component in these privately-provided services..."

Imagine your favourite social media platform does not let you post in English. Now think of a keyboard that won't allow you to type in your own words. You would have two options: either switch to another language or remain digitally silent. This is the reality for most people that speak indigenous languages and dialects. From a report: There are nearly 7,000 languages and dialects in the world, yet only 7% are reflected in published online material, according to Whose knowledge?, a campaign that aims to make visible the knowledge of marginalized communities online. While Facebook supports up to 111 languages, making it the most multilingual online platform, a survey published by Unesco in 2008 found that 98% of the internet's web pages are published in just 12 languages, and more than half of them are in English. This reduces linguistic diversity online to a handful of tongues, making it harder for those that speak one of the excluded languages of the internet.

An anonymous reader quotes a report from Ars Technica: In February, a researcher detailed a widely circulating Android backdoor that's so pernicious that it survives factory resets, a trait that makes the malware impossible to remove without taking unusual measures. The analysis found that the unusual persistence was the result of rogue folders containing a trojan installer, neither of which was removed by a reset. The trojan dropper would then reinstall the backdoor in the event of a reset. Despite those insights, the researcher still didn't know precisely how that happened. Now, a different researcher has filled in the missing pieces.

Last week, Kaspersky Lab researcher Igor Golovin published a post that filled in some of the gaps. The reinfections, he said, were the result of files that were downloaded and installed by a notorious trojan known as Triada, which ran once the xHelper app was installed. Triada roots the devices and then uses its powerful system rights to install a series of malicious files directly into the system partition. It does this by remounting the system partition in write mode. To make the files even more persistent, Triada gives them an immutable attribute, which prevents deleting, even by superusers. (Interestingly, the attribute can be deleted using the chattr command.) A file named install-recovery.sh makes calls to files added to the /system/xbin folder. That allows the malware to run each time the device is rebooted. The result is what Golovin described as an "unkillable" infection that has extraordinary control over a device.

Sony has revealed the DualSense, PlayStation 5's new controller that will "bring a sense of touch to PS5 gameplay." IGN reports: Announced on PlayStation.Blog, the DualSense will keep "much of what gamers love about DualShock 4 intact, while also adding new functionality and refining the design." Touch was a big inspiration when designing the DualSense, and haptic feedback is one of the ways this new controller will help bring PS5 games to life. Sony mentions that this feedback will add " a variety of powerful sensations you'll feel when you play, such as the slow grittiness of driving a car through mud." Adaptive triggers have also been incorporated to the L2 and R2 buttons, which will help players "feel the tension of your actions, like when drawing a bow to shoot an arrow."

The angle of the hand triggers were changed and some subtle updates were made to the grip. One thing that will be missing from the DualSense is the "Share" button that was featured on the DualShock 4. Sharing from the controller is not gone, but that previous button was replaced by the new "Create" button. Sony promises more details will be revealed on this change as we get closer to PlayStation 5's launch. DualSense will also have a built-in microphone array that will allow players to easily chat with friends, even for those who don't own a headset.

As for the controller's color, it is a bit of a non-traditional design as far as PlayStation is concerned. Usually, PlayStation controllers have a single color, but the DualSense has a two-toned design to make it stand apart. Additionally, the position of the light bar, which will be returning, was moved to "give it an extra pop." Now, the light bar sits on either side of the touch pad, as opposed to the top of the controller. Here's a picture of the front of the controller:

Teachers at some schools across the country report that fewer than half of their students are participating in online learning. From a report: Chronic absenteeism is a problem in American education during the best of times, but now, with the vast majority of the nation's school buildings closed and lessons being conducted remotely, more students than ever are missing class -- not logging on, not checking in or not completing assignments. The absence rate appears particularly high in schools with many low-income students, whose access to home computers and internet connections can be spotty. Some teachers report that fewer than half of their students are regularly participating.

The trend is leading to widespread concern among educators, with talk of a potential need for summer sessions, an early start in the fall, or perhaps having some or even all students repeat a grade once Americans are able to return to classrooms. Students are struggling to connect in districts large and small. Los Angeles said last week that about a third of its high school students were not logging in for classes. And there are daunting challenges for rural communities like Minford, Ohio, where many students live in remote wooded areas unserved by internet providers.

Linux 5.6 "has a bit more changes than I'd like," Linus Torvalds posted on the kernel mailing list, "but they are mostly from davem's networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary..." TechRadar reports that the new changes include support for USB4 and GeForce RTX 2000 series graphics cards with the Nouveau driver: Yes, Turing GPU support has arrived with the open source Nouveau driver, along with the proprietary firmware images, as Phoronix.com reports. However, don't get too excited, as re-clocking doesn't work yet (getting the GPU to operate at stock clocks), and other important pieces of the puzzle are missing (like no Vulkan support with Nouveau). For the unfamiliar, Nouveau is an alternative to Nvidia's proprietary drivers on Linux, and although it remains in a relatively rough state in comparison, it's still good to see things progressing for Linux gamers with one of Nvidia's latest cards in their PC.

Linux 5.6 also introduces fresh elements on the AMD front, with better reset support for Navi and Renoir graphics cards (which helps the GPU recover if it hits a problem)... Another notable move is the introduction of WireGuard support, a newcomer VPN protocol which makes a potentially nifty alternative to OpenVPN.

Linux 5.6 also supports the Amazon Echo speaker, and naturally comes with a raft of other minor improvements...
Linus's post also notes that for the next release's timing they'll "play it by ear... It's not like the merge window is more important than your health, or the health of people around you." But he says he hasn't seen signs that the pandemic could affect its development (other than the possibility of distraction by the news).

"I suspect a lot of us work from home even normally, and my daughter laughed at me and called me a 'social distancing champ' the other day..."

An anonymous reader quotes a report from Ars Technica: Huawei is still using components made by U.S. companies in its newest flagship smartphone, a Financial Times teardown has found, despite the U.S. all but blacklisting the Chinese telecoms equipment manufacturer. The teardown was done by XYZone, a Shenzhen-based company that disassembles smartphones and identifies the suppliers of their components. The biggest surprise was that some parts from U.S. companies were still ending up in the newest Huawei smartphone, despite the U.S. all but banning its companies from selling to the Chinese tech company.

The P40's radio-frequency front-end modules were, according to XYZone's teardown analysis, produced by Qualcomm, Skyworks, and Qorvo, three U.S. chip companies. RF front-end modules are critical parts of the phone that are attached to the antennas and required to make calls and connect to the Internet. The Qualcomm component is covered by a license from the U.S. Commerce Department, according to a person familiar with the company. [...] The "Entity List" designation means that U.S. companies have to apply for a license to export any U.S.-origin technologies to Huawei. The U.S. government has granted a "temporary general license" to its companies, allowing them to sell to Huawei to service existing products -- helping clients such as telecoms carriers that may need to replace parts of their wireless equipment. But the general license does not cover sales for the purpose of making new products, such as the P40 smartphone. For that, companies must seek individual licenses, and the Department of Commerce has not said which ones it has granted them to. A spokesperson for Huawei said the company has "always complied with any export control regulations of various countries, including the United States" and that "all the product materials are obtained legally from our global partners, and we insist on working with our partners to provide consumers with high quality products and services."

Also missing from the P40 are parts from U.S. chipmaker Micron. "Micron made the storage devices called NAND flash memory chips for some batches of last year's P30 smartphone, and South Korea's Samsung made the same chips for other batches," reports Ars. "The FT's copy of this year's P40 Pro appears to have only Samsung NAND flash memory chips."

"[W]e're missing out on the everyday exchanges that make us human..." argues a press release from Tinder. "And while we all know we need to stay home, the Tinder community has shown us that this doesn't mean we have to be alone with our thoughts and a tower of Top Ramen..."

"Many of our current subscribers are even reaching out across the world, using the Passport feature, to find solidarity with matches 1000s of miles away. And that's why starting next week we will make our Passport feature, which allows you to connect with anyone, anywhere in the world, available for free to all members through April 30th."

Newsweek reports: While traditionally the feature is reserved Tinder Plus and Gold members, the app acknowledges that having someone to chat with can make self-quarantining all the more bareable [sic]... In another press release, the app divulged that as areas become more isolated, new conversations spring up and tend to last longer. Tinder users are also swapping empathy for coolness, updating their bios to check ins like "how is everyone" instead of a silly catchphrase or their height.
"Our hope is that our members can use the Passport feature to transport themselves out of self-quarantine to anywhere in the world," Tinder writes in its press release.

In other news, Tinder has also cancelled the release of its apocalyptic-themed, in-app video series, "Swipe Night."

Linus Torvalds tells ZDNet what he's learned about working remotely: Torvalds admits that when he started, "I worried about missing human interaction -- not just talking to people in the office and hallways, but going out to lunch etc. It turns out I never really missed it."

Of course, just saying "'don't be social' isn't much of a great tip, is it?" Nor, as many extroverts are now finding out, is working from home necessarily at all comfortable. So, Torvalds suggests that you take "advantage of the 'real' upside of working from home: flexibility... Torvalds says, "if you make your new life a '9-5, but from home' kind of thing, I think you're just going to hate your home, yourself and your life. All the downsides, none of the upsides...." He believes that instead of using "video conferencing instead to recreate exactly what we used to do before, you should" try to really change how you work. Use asynchronous communication models: messaging, email, shared calendars, whatever.
Torvalds also recommends carefully tracking the things that you need to do, but argues that if you're spending hours in online meetings from home instead of hours in real-world meetings, "you've just taken the worst part of office life, and brought it home, and made it even worse..."

And the article also includes some tips from James Bottomley, an IBM Research Distinguished Engineer and senior Linux kernel developer who works closely with Torvald. For videoconferencing Bottomley uses NextCloud Talk and Zoom, which he calls a "horrible proprietary app" -- but notes that it does have binaries for every Linux distro.

One of the biggest new additions to Apple's new iPad Pro is a new "Light Detection and Ranging" (LIDAR) system on the rear camera, which Apple argued was the missing piece for revolutionary augmented reality applications. "It claims that by combining the depth information from the LIDAR scanner with camera data, motion sensors, and computer vision algorithms, the new iPad Pro will be faster and better at placing AR objects and tracking the location of people," reports The Verge. "But it doesn't change the fact that, right now, there still aren't a lot of compelling reasons to actually use augmented reality apps on a mobile device beyond the cool, tech-demo-y purposes that already exist." From the report: R apps on iOS today are a thing you try out once, marvel at how novel of an idea it is, and move on -- they're not essential parts of how we use our phones. And nearly three years into Apple's push for AR, there's still no killer app that makes the case for why customers -- or developers -- should care. Maybe the LIDAR sensor really is the missing piece of the puzzle. Apple certainly has a few impressive tech demos showing off applications of the LIDAR sensor, like its Apple Arcade Hot Lava game, which can use the data to more quickly and accurately model a living room to generate the gameplay surface. There's a CAD app that can scan and make a 3D model of the room to see how additions will look. Another demo promises accurate determinations of the range of motion of your arm.

The fact that Apple is debuting the iPad for AR doesn't help the case, either. While Apple has been rumored to be working on a proper augmented reality headset or glasses for years -- a kind of product that could make augmented digital overlays a seamless part of your day-to-day life -- the iPad (in 11-inch and 12.9-inch sizes) is effectively the opposite of that idea. It's the same awkwardness of the man who holds up an iPad to film an entire concert; holding a hardcover book-sized display in front of your face for the entire time you're using it just isn't a very natural use case.

It's possible that Apple is just laying the groundwork here, and more portable LIDAR-equipped AR devices (like a new iPhone or even a head-mounted display) are on their way in the future. Maybe the LIDAR sensor is the key to making more immersive, faster, and better augmented apps. Apple might be right, and the next wave of AR apps really will turn the gimmicks into a critical part of day-to-day life. But right now, it's hard not to look at Apple's LIDAR-based AR push as another hardware feature looking for the software to justify it.
