Android towards Realism and Kinecting again! [16May11] - 0 views

  • Adding realism to AR by using real world surrounding information (HDRs panoramas, IBLs) is a thing we all want to have sooner than later! We have seen a cool demo of Suomi’s VTT on this, where they fake the surrounding information using the background and scanning a ping pong ball for lighting information. Now we have another candidate porting a similar approach to our beloved mobile devices. The paper of the University of Münster (Germany) has been published already in 2004 (titled “Virtual Reflections for Augmented Reality Environments”), but now it’s time to hit the mobile world with it!
  • If you are interested in some tech talk, please read on! :-) Their approach can create CubeMaps for all reflective or lighting purposes in real-time using only the information from the background video frame: they not only flip and stitch the frame six times and mirrored together, but do a pretty smart estimation, that yields in plausible neat-looking reflections (although obviously fake): they project six regions of the background frame (see below) onto the new six sides of a Cube. The general idea is to have reasonable regions to map from
  • This way they get to simulate glossy and diffuse reflections already. Lighting/shadow influence will probably be the next step, since the CubeMap is already there…

  • This ongoing flurry of activity is underpinned by a common desire to conquer three important categories of growth for consumer-oriented Internet companies: mobile, social and local commerce. The race to find the right mix is crucial for capturing revenues and the loyalty of consumers whose sources for information and entertainment are becoming increasingly fragmented.
  • some members of the startup and funding communities are looking for the next wave. “I’m really searching far and wide for new ideas,” Rosa said. “There seem to be a lot of clones. ... There’s this behemoth ball of social and apps and mobile, and they’re just tacking onto this ball and rolling along. We’d like to see some more snowballs.”

Metaio and Layar pinpoint next steps for augmented reality [17May11] - 0 views

  • Metaio thinks that tablets will become increasingly important devices for AR, describing them as "the perfect enabler for augmented reality" as it published a video showcasing its Junaio AR technology running on slate devices.
  • Metaio's bullishness is about more than just the iPad: the company thinks the new wave of tablets running Google's Android 3.0 operating system – starting with the Motorola Xoom – will create new opportunities for innovative AR applications.
  • It also cites dual-core processors as a key factor enabling tablets to be used for AR applications including instructional guides; product information; e-commerce; entertainment and gaming
  • ...1 more annotation...
  • Metaio's view is that AR is "more than a marketing gimmick or hype, it's actually an interface revolution". However, there are currently relatively few companies able to take part in this revolution, since creating AR content remains the preserve of developers willing and able to get to grips with the tools.

Emotion transference: Telenoid [22May11] - 0 views

  • As a clinician fascinated by the use of new technologies to achieve outcomes, it’s hard to go past anything that is looking at bridging the divide between human emotions / touch and technology. Telenoid is one such project. It’s aim is to provide an effective way to transfer people’s presence. The research on telepresence is booming and it’s fairly widely accepted that videoconferencing is superior to teleconferencing and that platforms like virtual worlds provide even better telepresence sometimes. Telenoid is a step further again, providing a tangible means of interacting with someone remotely. In the second video below you’ll see its creator citing a key inspiration was the ability for remotely located grandparents to interact more with their grandchildren. That alone is laudable but for me the clinical simulation potentials stood out pretty strongly.
  • Real patients as simulation Imagine the ability to have a ‘patient’ reflecting the emotions and speech of a real person in combination with the current simulation functionality i.e. feedback, monitoring of biometric data etc. Taken a step further: a real patient experiencing a real health issue is able (with consent of course) to have their experience transferred to a simulation exercise in real time. There are already consumer devices on the market able to control avatars via thought processes, this is only a small step beyond that.
  • A specific example:

  • b. She consents to her next outpatient chemotherapy session being used for simulation purposes with third-year nursing students at a local university.
  • c. On arrival at the clinic for her chemotherapy, Marjorie agrees to wear a discreet headset that both captures her emotions as well as her voice as she goes through the process.
  • d. At the university the students are in a laboratory environment set up for chemotherapy and the simulation mannikin is reflecting Marjorie’s experience as students use the same clinical pathway as the clinic to simulate providing the chemotherapy. The voice recorder allows the students to hear what the nurse is actually doing for Marjorie, providing the opportunity to contrast practice and to ‘see’ what impact that practice is having on Marjorie.

The Future Of GPS Navigation With Wikitude Drive [26May11] - 0 views

  • Now Mobilizy, the leaders in augmented reality geo-location applications for mobile have taken the next major leap by combining augmented reality with GPS navigation software. Wikitude Drive is the award winning GPS navigation application for Android devices, it has already been awarded numerous prizes including the “Galileo Master 2010” of the European Satellite Navigation Competition, “Global Champion” of the NAVTEQ LBS Challenge and Winner of the “World Summit Award 2010”. Previously available for Austria, Germany and Switzerland the application is now available for Spain, UK, France and Italy. What’s different about Wikitude Drive from other navigation applications is it overlays the live route over the camera feed rather than using a traditional map view.  This new augmented reality view enables you to see exactly where you are going and the route without having to take your eyes off the road ahead. Having said sometime back that someday AR will change navigation, it’s been enjoyable playing around with the beta and testing the UK maps. As everything is stored on the server all the maps are up to date and I was even able to navigate to my house which hasn’t even made Google Street View yet. Turn by turn instructions are given clearly using a speech engine so you’ll always have the expected voice instructions.

Next Century's Winners Will Master Machine-to-Object Communication, Leading Observer Sa... - 0 views

  • Mark Roberti, founding editor of the publication RFID Journal, writes in an editorial this month that while M2M communication has great potential, the "real value" for sensor technology lies in machine-to-object communication.
  • "On the other hand, a firm could put passive ultrahigh-frequency (UHF) transponders inside a container at various levels. Since the liquid would interfere with the ability to read the tags, a company could determine liquid levels by ascertaining which tags can and can not be read...you can't put a Wi-Fi transmitter or a cell phone on every box of Tide detergent, bag of Granny Smith apples or Van Heusen shirt. Low-cost RFID tags will, one day, be put on all of these things, enabling M2O communication."
  • Leading wireless industry analyst Chetan Sharma detailed a similar vision to us in an interview earlier this year. (How 50 Billion Connected Devices Could Transform Brand Marketing & Everyday Life.) Sharma talked with us about cereal boxes with sensors inside them.
  • ...2 more annotations...
  • Roberti says this will be a defining opportunity for the rest of the century. "This change - enabling computers to see and understand what is happening in the real world - is enormous. Most people have yet to grasp it, seeing RFID as a more expensive alternative to bar codes. They don't comprehend that when computers can automatically collect information regarding what is happening in the world, new insights and business strategies then become possible. And the companies that leverage these capabilities most effectively will be the big winners in the century ahead."
  • Such a vision raises questions of consumer privacy, data ownership, silos vs. effective cross-company development platforms, corporate vs. consumer power and much more.

Qualcomm Talks Future of Mobile, AR, 3D, Sensors & More at Uplinq 2011 [01Jun11] - 0 views

  • People Don't Care about PCs...the Buzz is All About Mobile To paint an image of the very large scale of the mobile ecosystem, Jacobs talked numbers: There are 1.3 billion 3G connections worldwide, and there will be 2 billion more connections by 2015. Mobile data use will increase 10 to 12 times over the next four years. There are over 120 HSPA+ mobile networks and 180 commercial EVDO networks offering mobile broadband. There are 200 LTE networks planned, 20 of which have launched now.
  • Mobile Unleashing the "Greatest Wave of Creativity in History" And what is that? Only that mobile is going to unleash the "greatest wave of creativity in history." Dr. Jacobs said he knew that sounded like a "heady" proposition, especially because many mobile developers are just trying to build an app people like, he says. "But your app could reach hundreds of millions of users!" Now is the time to "think and act globally," Jacobs said. "Mobile is now the dominant computing platform, and it's never going back."
  • Augmented Reality Demoed as Marketing Tool AR, or augmented reality, was also at the forefront of today's keynote, with a sobering presentation from John Batter, Co-President of Production, Dreamworks Animation SKG. He produced data showing the decline of DVD sales over the years.
  • ...2 more annotations...
  • He showed an example of this with the studio's new hit, Kung Fu Panda 2, which will be marketed using in-store signage at major retailers like Walmart and Target. The signs feature QR codes that, when scanned, make an AR-enabled app available to end users
  • Mobile is "Digital 6th Sense" Dr. Jacobs concluded the keynote by looking forward into the future of mobile, calling mobile our "digital 6th sense" which will become the primary way we interact with the world around us. Your phone will listen and see everything using the sensors connected to your body, sensors out in the environment, the people around you and more - and it will adjust itself accordingly. Imagine a phone that adjusts to your mood, or your vital signs, he said. "You are the creators of this experience," Jacobs said, speaking to the developers in the audience. Qualcomm just wants to "free you up to do what you do best: innovating."

Redefining the E-Book Experience [14May11] - 0 views

shared by Dan R.D. on 14 May 11 - No Cached
  • Ever since Amazon released the Kindle, it now sells more e-books than it sells physical books: Amazon reported that it sold 115 e-books for every 100 physical books it sold in 2011. Unfortunately, e-books are still very much the same as physical books: they are static, their content is not updated nor does it include videos or interactive infographics.
  • If you have an iPhone/iPad/iPod, we highly recommend downloading “Our Choise”. Not only is it an intelligent and interesting book, its format is the first peek into what your book experience will become in the next few years. It might be time to kiss those physical books goodbye after all.  If you’re not convinced, check out the great demo given at TED:

Building Mobile Web Apps the Right Way: Tips and Techniques [09May11] - 0 views

  • Here’s a quick breakdown of the big differences between desktop and mobile platforms: Mobile device hardware is smaller and generally tends to have lower hardware resources than desktops/laptops. Smaller screens bring about different design considerations and challenges. Touchscreen technology introduces new interaction concepts that differ from traditional input devices (keyboard and mouse). With a mobile device, internet connectivity is not always as reliable as a hard-wired broadband connection, which means internet connectivity is a concern and data transfer could be significantly slower. Although these sound as if they are hurdles to get over, with careful thought and consideration, there’s no reason why they should be. Touchscreen technology is exciting. The smaller screen design will really make you think about how to get the user to interact with your mobile web app in the most satisfying way possible. What we should really be doing is looking at the list of differences above and seeing opportunities to deliver our content in a different way. Building mobile web apps will be a paradigm shift from traditional web development and web design.
  • In the next sections, we will discuss development/design considerations, as well as concepts and techniques for building mobile web apps.
  • Keep File Sizes Small
  • ...11 more annotations...
  • Dealing with Image Performance We want to try to get rid of as many images as we can. For the images we keep, we want them to be as lightweight as possible. If images are a necessity for particular parts of your mobile web app design, then there are a couple of extra steps we can use to trim off any excess fat from your files.
  • Use Adobe Fireworks for Transparent PNGs
  • Using ImageAlpha If Fireworks sounds like too much of a bother, check out ImageAlpha. Once installed, all you need to do is drag your images into its main window and then tweak the export settings to remove excess data from the images.
  • To learn more about using PNGs in web designs, see the Web Designer’s Guide to PNG Image Format.
  • Leveraging CSS3 Mobile web browsers these days are pretty advanced. Android devices use a mobile version of Google Chrome, whilst the iPhone does the same with Apple’s Safari. Some mobile devices come with mobile Opera and others allow you to install a browser of your choice such as mobile Firefox. So we’re talking about some pretty good browsers in terms of CSS3 and HTML5 feature support. CSS3 allows us to render things through code that would previously have required an image. We can use color gradients, draw rounded corners, create drop shadows, apply multiple backgrounds to HTML elements, and more — all of which can help improve performance and decrease development times.
  • If you look at a typical application interface via your smartphone, it’s almost guaranteed that you’ll find CSS3 being used.
  • By using CSS3, we can reduce data transfer — particularly images and possibly excess HTML markup. We let the browser and the device do the work to render the interface more quickly.
  • HTML Canvas If you fancy a little more work, then you can improve speed even further using the canvas element. Although using CSS gradients eradicates the loading of a physical image, that method still causes the device’s rendering engine to construct an image in the browser, which can result in a performance reduction depending on the device and browser.
  • Hardware Acceleration When it comes to mobile web apps, Apple’s mobile devices are a major consideration that we need to be aware of because of the current popularity of the iPhone and iPad. Safari 5 (on all platforms) brings hardware acceleration into the mix. If you’re not familiar with the feature, Apple describes it as follows: "Safari supports hardware acceleration on Mac and PC. With hardware acceleration, Safari can tap into graphics processing units to display computing-intensive graphics and animations, so standards like HTML5 and CSS3 can deliver rich, interactive media smoothly in the browser."
  • Be Cautious of CSS3 Rendering Performance As brilliant as CSS3 is, certain properties can slow down a web page. WebKit-based browsers, for instance, really seem to struggle with shadows in particular, so just be careful that you don’t apply too many of these to elements of your interface until the issue has been resolved.
  • Consider the Offline User Experience Finally, let’s briefly discuss HTML5 offline data storage.

EU Demands Explicit Geo-Location Permissions [20May11] - 0 views

  • "Apple, Google and employers are already contravening new European Union rules that will require companies to get explicit permission from users before any geo-location data can be used to track them, whether for the purposes of targeted advertising or monitoring employee behavior. This could be the start of the next big privacy argument. The hopes of companies planning to use geo-location data to push products and services to mobile device users have taken a beating in the European Union, following a pronouncement from the European Data Protection Supervisor, Peter Hustinx."

Gupta: Cell phones, brain tumors and a wired earpiece [20May11] - 0 views

  • Do cell phones cause brain cancer? It may be too early to say for sure. The latency period or time between exposure and recognition of a tumor is around 20 years, sometimes longer. And, cell phone use in the U.S. has been popular for only  around 15 years. Back in 1996, there were 34 million cell phone users. Today there are 9-10 times as many. Keeping that in mind, it is worth taking a more detailed look at the results of Interphone, a multinational study designed to try to  answer this question. The headline from this study was there was little or no evidence to show an association between cell phones and cancer. Though, if you went to the appendix of the study, which interestingly was available only online, you found something unsettling. The data showed people who used a cell phone 10 years or more doubled the risk of developing a glioma, a type of brain tumor. And, across the board – most of the studies that have shown an increased risk are from Scandinavia, a place where cell phones have been popular since the early 1990s. For these reasons, the whole issue of latency could become increasingly important.
  • Cell phones use non-ionizing radiation, which is very different from the ionizing radiation of X-rays, which everyone agrees are harmful. Non-ionizing radiation won’t strip electrons or bust up DNA. It's more like very low power microwaves. Short term, these microwaves are likely harmless, but long term could be a different story. Anyway, who likes the idea of a microwave, even a low-powered one, next to their head all day?
  • And, what about kids?

Gartner releases the 1Q11 worldwide mobile sales report: Android and HTC the winners [2... - 0 views

  • Gartner has just released its Worldwide Mobile Terminal Sales to End Users report for 1Q11, and results confirm the expectations: Android keeps growing and is with no doubt the number one platform, while Nokia is still the strongest manufacturer even though at its minimum level since 1997. The other great winner is the Taiwanese HTC, which sells almost triple amount of handsets thanks especially to its Android smartphones.
  • Nokia keeps loosing share but keeps first position, with Samsung holding number two with a slight loss in percentage but growth in sales. LG loses ground too and is now pushed by Apple and RIM. ZTE keeps growing, and just behind it HTC passes two of the bigger names from the past that are today relegated to bottom positions: Motorola and Sony Ericsson. Huawei closes the top ten thanks to its low-price devices. Can we expect HTC to pass ZTE and maybe even RIM before the next report? With amazing superphones such as the Sensation and the Thunderbolt that’s very possible! “Smartphones accounted for 23.6 percent of overall sales in the first quarter of 2011, an increase of 85 percent year-on-year”, said Roberta Cozza, principal research analyst at Gartner. “This share could have been even higher, but manufacturers announced a number of high-profile devices during the first quarter of 2011 that would not ship until the second quarter of 2011. We believe some consumers delayed their purchases to wait for these models”.
  • The smartphones report shows a huge growth by the Android OS, which is now firmly the platform to sell the most, with Symbian dropped to number two, and iOS third after surpassing BlackBerry OS. Microsoft OSs (both Windows Phone 7 and the older Windows Mobile, combined) mantains the same sales level of last year but halving its percentage; experts say Microsoft’s alliance with Nokia will bring Windows Phones back to the top replacing Symbian,

Robots Successfully Invent Their Own Language [18May11] - 0 views

  • "One group of Australian researchers have managed to teach robots to do something that, until now, was the reserve of humans and a few other animals: they've taught them how to invent and use spoken language. The robots, called LingoDroids, are introduced to each other. In order to share information, they need to communicate. Since they don't share a common language, they do the next best thing: they make one up. The LingoDroids invent words to describe areas on their maps, speak the word aloud to the other robot, and then find a way to connect the word and the place, the same way a human would point to themselves and speak their name to someone who doesn't speak their language."

Global Internet Traffic Expected to Quadruple by 2015 [INFOGRAPHIC] - 0 views

  • Global Internet traffic is expected to quadruple between 2010 and 2015, according to data provided to Mashable by Cisco.By that time, nearly 3 billion people will be using the Internet — more than 40% of the world’s projected population. On average, there will be more than two Internet connections for each person on Earth, driven by the proliferation of web-enabled mobile devices.Internet traffic is projected to approach 1 zettabyte per year in 2015 — that’s equivalent of all the digital data in existence in 2010. Regionally speaking, traffic is expected to more than double in the Middle East and Africa, where there will be an average of 0.9 devices per person for a projected population of 1.39 billion. Latin America is close behind, with a 48% increase in traffic and an estimated 2.1 devices per person among a population of 620 million.The rest of the world will experience more moderate growth in terms of traffic, but the number of devices per person is forecast to increase significantly. By 2015, there will be an average of 5.8 devices per person in North America, 5.4 in Japan and 4.4 in western Europe.
  • Somewhat surprisingly, it is neither mobile phones nor tablets that are expected to grow the most in the next four years. Rather, flat panel televisions will experience the greatest production increase globally, up 1063% from 2010, followed by tablets (750%), digital photo frames (600%) and ereaders (550%). The number of non-smartphones and smartphones is expected to increase by 17% and 194% worldwide, respectively

Big Data: Cornerstone for the Next Wave of Change [04Jun11] - 0 views

  • Faster, denser and cheaper hardware is enabling users to create and store incredibly more data than has ever been possible.  Currently, the amount of business data is doubling every 1.2 years.  As of 2010, global enterprises in total stored more than 7 exabytes of business data.  A McKinsey report (McKinsey Global Institute) identifies all this data as being at the source of another upcoming wave of change.
  • Big Data Analytics (BDA) could positively transform our lives.  When applied to applying collected shopper information, big data would give retailers the potential to increase their operating margins by more than 60 percent says the McKinsey report.  When BDA is applied to health care information, the quality of health care could dramatically improve, efficiencies in the health care delivery system would increase, and health care costs could drop as much as 8 percent, creating as much as $300 billion in value annually.
  • The increasing volume and detail of information captured by enterprises, together with the rise of multimedia, social media, and the Internet of Things will fuel exponential growth in data for the foreseeable future.  Data have now reached every sector in the economy.”

Next time with feeling - Sentiment Analysis hocum [20Jun11] - 0 views

  • The data that twitter can supply is good for basic mentions, the basic smell of the situation - just not it's meaning -good/ bad, action required, not required. It's a canary in the mine, but it can't tell you what gas it is. This what many brand/ marcomms research dashboards supply - but many aren't optimised for the 'now take action' moment - they are mostly like webcams of rivers - an ongoing situation goes on. What does work is smart , linguistics trained researchers, alerted by flagged moments in data inputs, then raking through data/ tweets to find meaning. Machines are useful for sorting these out but real meaning comes from human analysis still. Your engineers could help by writing some scripts that help the sifting/ alerting. Everywhere data is used for analysis, a human is required for the real interpretation. The robots just aren't that smart yet.

Your favorite gadgets are threatening the planet's future [18Jun11] - 0 views

  • Earth is expected to be home to over nine billion people by 2050. That’s a lot of people for Mother Nature to manage.
  • Space issues aside, the biggest concern on an over-populated planet is whether or not there will be enough resources to go around. Last week, British investor and Co-founder of Grantham Mayo Van Otterloo (GMO) Jeremy Grantham offered what Business Insider called a “startlingly depressing outlook for the future of humanity.”
  • the purpose of this piece isn’t to tread well-worn ground about the planet’s perils. So forget about fossil fuels, drinking water, crops, ice-caps, trees and animals for now. What we’ll be looking at is all those elements that go into helping you do what you’re doing right now.

  • Ethical electronics
  • Tantalum
  • Besides the direct environmental impact of mining the Earth, there is a more immediate threat. You’ve no doubt heard about conflict diamonds or ‘blood diamonds‘, which are diamonds mined in a war zone and sold to finance an insurgency, invading army’s war efforts or a warlord’s activity. Well, your mobile phone contains a similarly valuable commodity that’s been at the center of controversy in recent times
  • Tantalum is one of the best superconductors on Earth, and it’s used to coat capacitors to obtain more power from less energy. This basically means that laptops and mobile phones don’t need batteries that are larger than the device itself – so this is one of the chief reasons why you can slip your iPhone in your pocket rather than carting it around in a wheelbarrow. In central African countries such as The Democratic Republic of Congo,the mining of the mineral coltan – from which tantalum is extracted – it has often been argued fuels wars and encourages child slavery. And these arguments are well-founded.
  • However, the majority of tantalum production shifted to Australia, and Western Australia became the world’s largest source of mined tantalum concentrates. The mine closed in late 2008, and has only recently reopened.
  • In 2010, major concerns were raised as to the availability of tantalum and the effect this would have on the supply chain. “The impact, the real concern, is actually obtaining the metal,” said Dennis Zogbi, CEO of Paumanok Publications, which researches the component industry and the tantalum markets. If the stockpile of tantalum ever runs out, this could be disastrous for the electronics industry.
  • Tantalum minerals are also mined in Canada, China, Ethiopia, and Mozambique, and mass reserves were found in Venezuela in 2009, and in Columbia a year later.
  • Bloomberg reported a couple of weeks ago that the first conflict-free tantalum has recently been certified by The Electronic Industry Citizenship Coalition and Global e- Sustainability Coalition (EICC/GeSI), an initiative backed by companies such as Apple and Intel.
  • Indium
  • Then there’s Indium, a rare chemical element you may or may not have heard of. Zinc ores are the primary source of indium, which – when isolated – is then used in liquid crystal displays (LCDs) and touchscreens.
  • China is a leading producer of indium, whilst Canada and Bolivia are also large producers. And Cornwall, England, was also found to hold significant indium deposits earlier this year too, something which could prove massively beneficial to the UK economy
  • Last year, 85% of all indium was devoted to making indium tin oxide for use in LCD products, and the demand is predicted to grow at 15% a year over the next few years
  • A UN report published last month found that there are virtually no recycling initiatives in place for indium, and Thomas Graedel, one of the report’s eight authors, warned that a failure to re-use metals such as Indium doesn’t bode well for the future
  • “If we do not have these materials readily available at reasonable prices, a lot of modern technology simply cannot happen. We don’t think immediate shortages are likely but we are absolutely unable to make predictions based on the very limited geological exploration currently conducted.
  • The case for recycling
  • Your old mobile phone has circuit boards, batteries and an LCD screen – these all contain harmful materials that, when dumped in landfill sites, eventually break down and leak into the environment.
  • Over time, the likes of lead, cadmium and mercury pollution can be hazardous to the environment and to our health. It was for this reason that, in 2006, California became the first US state to make it mandatory for all mobile phone retailers to establish a collection and recycling program for mobile phones. The law also prevents residents from disposing of old mobile phones.
  • It’s very difficult to reclaim tantalum once it has been transposed onto an electronic component. For this reason, it’s important that you choose how you dispose of old devices carefully. Some organizations will promise to ‘safely’ recycle your handset, but this is very vague and may not mean the components are being reused. Given the amount of effort and strife that may have gone into producing it, you should ensure that it is actually reused. But this is something governments and industries need to help consumers achiev
  • The UN report analyzed the recycling rates of 60 metals, and 34 of these have recycling rates of less than 1%. Among the least-recycled metals were tellurium and gallium – which are used in solar cells – and lithium, a key element in your phone and laptop batteries.
  • Despite the best efforts of environmentalists, governments, businesses and consumers, there could be another ‘small’ obstacle to contend with if we’re to protect the Earth’s natural resources. And that is China
  • As reported recently in National Geographic, China supplies 97% of the world’s so-called rare earth elements, elements we all rely on for all our high-tech gadgetry, including mobile phones and laptops. And in 2010, China gave a hint of what the future may hold for the rest of us, when it stopped shipments of rare earth elements to Japan for a month following a diplomatic dispute. This had a big impact on the price of rare earths on global markets. China is expected to reduce its rare earth exports to help protect the country’s own rapidly growing industries. Indeed, it’s worth noting that almost two-thirds of rare earth metals produced in China are already consumed ‘in-house’, so to speak.
  • If China does decide to cut back on its exports, global prices will sky rocket. Dysprosium, for example, is used in hard-drives and it now sells for over $200 a pound (roughly half a kilo), but the disturbing thing is that the price was only about $7 eight years ago
  • It’s thought that the global demand for many rare earth metals could exceed the supply as soon as the end of this year.
  • So how serious is this? Well, China has almost half of the planet’s rare earth reserves. The US holds about 13%, whilst Russia, Australia and Canada also has some stockpiles, so we’re not quite at the critical stage yet. But the writing is very much on the wall for many industries, not just electronics.
