Ferroelectric material could make your smartwatch run longer
Elon Musk's big plan involves charging your electric car with shingles that are solar panels. While that's incredibly impressive -- not to mention ambitious -- it uses only one form of alternative energy. Finnish scientists have a different idea: harnessing heat, kinetic energy and sunlight simultaneously to help power your gadgets. This involves using a ferroelectric material (think: the stuff inside ultrasound machines or fuel injectors for diesel engines), KBNNO, to generate electricity from heat and pressure. That's according to a post on Phys.org.
Computers learn how to spot hidden facial expressions
Machines are good at spotting obvious emotions like smiles, but they're not so hot at detecting the extremely brief microexpressions that reveal when people are covering up their true feelings. They may have a keener eye in the future, though: researchers have developed a computer vision algorithm that magnifies facial expressions, making it possible to catch the tiniest bit of displeasure or surprise. While some humans have a knack for spotting these subtle cues, the algorithm is far more effective in early tests -- you likely wouldn't fool the computer into thinking everything was hunky dory.
IndoorAtlas uses disturbances in the (geomagnetic) force to map interiors, plot a path to aisle 3 (video)
Interior navigation is only just coming into its own, but IndoorAtlas has developed a technology that could make it just as natural as breathing -- or at least, firing up a smartphone's mapping software. Developed by a team at Finland's University of Oulu, the method relies on identifying the unique geomagnetic field of every location on Earth to get positioning through a mobile device. It's not just accurate, to less than 6.6 feet, but can work without help from wireless signals and at depths that would scare off mere mortal technologies: IndoorAtlas has already conducted tests in a mine 4,593 feet deep. Geomagnetic location-finding is already available through an Android API, with hints of more platforms in the future. It will still need some tender loving care from app developers before we're using our smartphones to navigate through the grocery store as well as IndoorAtlas does in a video after the break.
Nokia and Intel build a joint research lab, plan to create the mobile 3D future
Thought Nokia and Intel's partnership was just some fleeting MeeGo fling? Just a carefree hookup in their times of mobile panic? Not quite. The companies are certainly in this thing for the long haul and today's announcement of their new research lab in Oulu, Finland is all the evidence you'll need. The Intel and Nokia Joint Innovation Center -- as it's been dubbed -- is part of the University of Oulu and will now be home to about two-dozen researchers. What exactly will the white coats be working on? Well, the 3D mobile internet, of course, technology that Nokia's been dabling with for awhile. The focus of the initial work will be on three-dimensional virtual reality platforms as well as on mapping. Sounds pretty neat and futuristic, but for some reason all we can keep thinking about is the immediate future of getting our hands on Nokia's MeeGo-running N9. Hit the break for the full press release and a few more details on the lab itself.
