Some smartwatches come with powerful processors, lots of storage, and robust software, but have limited capabilities compared to smartphones thanks to their tiny touchscreens. Researchers at Carnegie Mellon University, however, have now created a smartwatch prototype with a built-in projector that turns the wearer’s arm into a smartphone-sized touchscreen.

Despite what you may have seen on crowdfunding sites, the LumiWatch is the first smartwatch to integrate a fully-functional laser projector and sensor array, allowing a screen projected on a user’s skin to be poked, tapped, and swiped just like a traditional touchscreen. It seems like a gadget straight out of science fiction, but don’t reach for your credit card just yet, because it’s going to be a very long time before the technology created for this research project ends up in a consumer-ready device.

It might be worth the wait, though. Smartphones have managed to improve their functionality over the years by ballooning to the size of miniature tablets, but a wearable device like a smartwatch will always be limited in size. Imagine strapping a device as small as the original iPhone (tiny by today’s standards) to your wrist: It would feel monstrous on your arm. Smartwatch displays don’t have much room to grow, but at the same time, human fingers aren’t getting any smaller, and interacting with a tiny touchscreen has proven a major disincentive for many would-be adopters of the technology.

That’s what inspired the researchers at Carnegie Mellon University, who worked with ASU Tech Co. Ltd. in China, to develop the LumiWatch. At 50 millimeters in size, the current prototype is a bit larger than even the 42-millimeter Apple Watch. Instead of a touchscreen, however, it incorporates a 15-lumen pico laser projector, a ten-element sensor array, a quad-core CPU running Android 5.1, and a battery that’s good for an entire day of occasional use, or around an hour of continuous projection. All-in-all, the custom hardware cost around $600, which is actually cheaper than many fancy Wear OS watches.

The LumiWatch’s projector is pointed out the side of the watch, creating a 1024×600-pixel image on either the wearer’s arm or the back of their hand. Both orientations work equally well, but stop for a moment and take a look at your arm and hand. Does it look anything like the flat projector screen hanging on the conference room wall at work? Not even close. One of the biggest challenges to making a smartwatch projector isn’t the hardware at this point; it’s projecting an image from a low-angle onto an irregularly curved surface.

Correcting distortion on the projected image is one of the important breakthroughs that makes this smartwatch possible.

Generating a projected image that isn’t completely deformed by the unique shape of each wearer’s arm is the ‘secret sauce’ behind what makes the LumiWatch more than just a novel tech demo—it’s actually usable. A combination of custom software and graphics-processing hardware removes the image distortion and warping that usually occurs when projecting on an irregular surface, and it also helps ensure the projection is equally bright across the entire length of a user’s arm.

Correcting the projected image requires calibration for every user, however, because everyone wears a watch a little differently, and has different physical features. But instead of requiring users to go through an annoying re-calibration procedure every time they want to use the watch, the researchers have resurrected the “swipe to unlock” gesture. The watch’s sensors track the movement of the user’s finger as they swipe the slider, and by tracking the position and changing size of the finger as it moves toward the watch, the calibration calculations can be automatically made.

Projectors have always been the most convenient way to create a temporary but large screen, which makes them the ideal way to improve the functionality of smartwatches where you only occasionally want a larger touchscreen. Most of the time I only want to see the time or who’s texting me when when I glance down at my Apple Watch. But in the rare moments when I need to respond to a message, the idea of having a temporary keyboard instantly appearing on my arm is science fiction I want to be science fact as soon as possible.

The US is a latecomer to the world of offshore wind. The first commercial offshore wind farm in the US, a small, five-turbine, 30MW installation off the coast of Rhode Island, only just switched on in December 2016. Since then there have been no new offshore farms, although a few preliminary plans for new farms have been announced for coastal waters off New York and Massachusetts.

John McAfee-Backed Cryptocurrency’s Thousands of Investors Exposed in Data Breach

John McAfee-Backed Cryptocurrency’s Thousands of Investors Exposed in Data Breach

https://ift.tt/2HYSuBc

A leaky database discovered online contains a wealth of sensitive data belonging to thousands of investors in Bezop cryptocurrency, including photocopies their driver’s licenses and passports, according to a report from Kromtech Security.

Kromtech announced on Wednesday that Bezop, which offers its own cryptocurrency “tokens” in addition to… some sort of blockchain-based e-commerce app, left a MongoDB database wholly unsecured, exposing “full names, addresses, email addresses, encrypted passwords, wallet information, along with links to scanned passports, driver’s licenses, and other IDs for over 25,000 investors.”

Among the advisors named on the organization’s website is John McAfee, the former security software tycoon turned fugitive turned paid cryptocurrency hustler. (I am Jack’s utter lack of surprise.)

Earlier this year, McAfee revealed that he charges up to $105,000 to promote initial coin offerings (ICOs) on his Twitter account, which at time of writing boasts roughly 821,000 followers. He also announced in March that he was opening up his own “hackproof” crypto-security firm—whatever the hell that is.

“I have become an advisor to bezop.io,” McAfee wrote in a testimonial featured on Bezop’s website. “I recommended them recently and, as an early investor in their ICO, I want to make sure they succeed in implementation.”

Bezop was not immediately reached for comment.

In a statement to Threatpost, the organization’s CTO, Deryck Jones, said a notification was sent out earlier this year warning people that the Bezop had been targeted by a DDoS attack and also of “security holes exposing that data.” (Threatpost noted it was unsure if Jones was actually referring to the passports and other information uncovered by Kromtech.)

On Medium yesterday, Bezop disclosed that McAfee was paid to promote its cryptocurrency and said investors were notified about the breach on January 8. Kromtech, meanwhile, says the investors’ data was publicly accessible as late as March 30.

Bezop launched a “bounty” program in early January, according to Kromtech, around the time of its ICO. One of the tables in the exposed Bezop database, which researchers said was not protected by a password and could be accessed by virtually anyone online, was called “Bounty,” suggesting the data it contains may belong to the people who participated in the program.

“It does not seem to be a very good start for a company such as this to place personal information of anyone on the Internet and open to the public, especially it’s early investors,” Kromtech said.

“In fact, it’s a little difficult to grasp how it could happen, even if by mistake,” Kromtech added. “Given the changes to MongoDB, it would have to have been deliberately configured to be public, a configuration which should not even be risked internally.”

Google Maps Has Launched a Feature to Flag Prescription Drug Disposal Sites

Google Maps Has Launched a Feature to Flag Prescription Drug Disposal Sites

https://ift.tt/2Hy7p40

Google has partnered with the Drug Enforcement Administration to mark locations where people can safely dispose of excess prescription drugs on its Maps platform, the company announced in a blog post on Wednesday.

The search giant wrote that prescription drugs are a driver of opioid addiction and that the “majority of abused prescription drugs are obtained from family or friends, often from a home medicine cabinet”—something that is backed by medical surveys. According to Google, they partnered with the DEA to roll out the feature in advance of April 28th’s National Prescription Drug Take Back Day, which is intended to encourage people to take leftover medication to disposal sites:

Using Google Maps API, our team worked with the DEA to create a locator tool for the National Prescription Drug Take Back Day this Saturday, April 28. The locator tool can help anyone find a place near them to safely dispose of leftover prescription medications. Click on the image below to access the locator, and enter an address or zip code to find nearby Take Back Day events this Saturday and help fight the opioid epidemic.

Here’s a GIF of the feature in action, courtesy of Google:

Opioid deaths have skyrocketed across the country in recent years, with recent federal data showing that 63,632 people died of drug overdoses in 2016, with 42,249 of them involving at least one opioid. Synthetic opioids other than methadone, which tend to be far more powerful than non-sythetic ones, caused 10,375 deaths that year.

Since research shows many opioid users start with prescription drugs often prescribed by a doctor, aiding voluntary disposal of leftover pain pills or other prescription drugs before the temptation to use them strikes sounds helpful. It’s also probably good for the environment, seeing as flushing pharmaceuticals into waterways is a major source of pollution (though the Federal Drug Administration advises that scientists believe this is mostly a result of drugs that have passed through the body).

So this new Google Maps feature is innocuous enough! But it’s worth noting that despite vague commitment from Donald Trump’s White House to solve the opioid crisis, federal law enforcement agencies like the DEA have doubled down on failed “tough-on-crime” policies at the same time most Americans have realized that a public health approach is better. The president himself is reportedly in favor of anti-drug scare tactics of the Reefer Madness variety as well as executing drug dealers, so there’s that too.

Ford will stop selling most of its cars in North America

Ford will stop selling most of its cars in North America

https://ift.tt/2Ffbbxu


Ford

If there was any doubt that the auto industry is rapidly changing, Ford just delivered proof. The industry pioneer is scaling back its North American small car lineup in North America to just two vehicles, the Mustang and the unrevealed Focus Active crossover, in the “next few years.” The rest of its range will be limited to SUVs, trucks and commercial vehicles. Ford isn’t shy about its reasons: “declining consumer demand and product profitability” make it impractical to develop other sedans. You’d better act quickly if you’ve been looking at a brand new Fusion or Taurus.

While the brand wasn’t too specific beyond that, it noted that it was adding hybrid powerplants to many of its vehicles, ranging from the Mustang to historical gas guzzlers like the Explorer and F-150. It reiterated that it’ll launch its first all-electric vehicle (the Mach 1 SUV) in 2020, and that it would have 16 EV models on the market by 2022. Some of the incentives for buying small cars, such as fuel economy, are going out the window — you don’t need to buy a compact car to get decent mileage. Combine that with North America’s fondness for SUVs and small cars faced a major challenge.

There’s also the matter of overall declining car ownership. Even if you discount changing tastes and economic situations, there just isn’t as much reason to own a car as there once was. You can order many products online instead of visiting the store, and ridesharing can frequently cover quick trips. That’s before self-driving cars arrive, too. Why pour so much money into sedans when many people might hop into robotic cars?

Other automakers haven’t cut most of their lines, and we wouldn’t count on when competitors like Honda and Toyota are still committed. Just don’t be surprised if Ford’s move is the start of a trend rather than an exception.

Police take down the world’s largest DDoS-for-hire service

Police take down the world’s largest DDoS-for-hire service

https://ift.tt/2Hs1DVZ

The internet might be slightly safer against distributed denial of service attacks in the near future… slightly. Police in twelve countries have taken down WebStresser, believed to be the world’s largest service for paid DDoS attacks. The joint campaign (Operation Power Off) seized WebStresser’s infrastructure in the US, UK and the Netherlands, and busted site administrators ranging as far as Australia and Hong Kong.

It’s not clear just who was arresed, though security guru Brian Krebs found that one of them is likely Jovan Mirkovic, a 19-year-old Serbian. He used his Facebook account to openly discuss his role in WebStresser, and his last post was on April 3rd (the day before Operation Power Off took place).

Like many other cyberattack-for-hire services, WebStresser made it all too easy to knock sites offline on a whim. You could pay as little as $15 to flood a site with traffic, regardless of how little technical knowledge you had. Annoyed by a company’s practices, or just wanted petty revenge? You simply had to order an attack.

While authorities are touting this as a major victory, there’s good reason to be cautious. It doesn’t take much to start a new DDoS network, especially if you can wield botnets that will do the hard work in place of specialized servers. This is definitely a victory — it’s just unlikely to be a decisive one.

LG celebrates record profits by making its biggest ever acquisition

LG celebrates record profits by making its biggest ever acquisition

https://ift.tt/2r0vxpX


ZKW

LG has revealed its biggest acquisition yet shortly after it announced that it has reached its highest quarterly profit since 2009. The Korean corporation has snapped up Austrian company ZKW, which is known for manufacturing lighting and electrical systems used by European automakers like Audi, BMW, Daimler and Porsche. It’s one of the first companies to make matrix LED and laser headlights and was almost purchased by Panasonic for $885 million back in 2016 — LG had to shell out around US$1.3 billion to finalize its deal. So, why would LG buy a company that makes lights for premium cars? Two words: autonomous vehicles.

According to the company’s announcement, LG and ZKW will work on developing intelligent lighting solutions. Particularly, lighting technologies that can collect information from autonomous vehicle sensors and cameras and can project high-resolution warnings on roads based on that data. “In addition to strengthening ZKW’s product development capabilities,” LG chief Jo Seong-jin said in a statement, “LG’s global production experience and international business network will present unlimited opportunities for both companies in the auto market of tomorrow, which includes intelligent lighting solutions.”

While a $1.3 billion acquisition is a huge deal for a company like LG, it at least made $1.03 billion in operating profit for the first quarter of 2018. It said its sales rose 3.2 percent from the first quarter last year, thanks to its pricier appliances. Unfortunately, LG’s couldn’t say the same for its mobile division, which recorded an operating loss of $126.85 million. Sales apparently declined due to G7’s delay, but the company “expects to see positive results with the launch of the LG G7 ThinQ” in May.
