    The early days of VOIP calling required a lot of patience, as the half-second or more delay between you speaking and your conversation partner receiving often turned the convo into a start and stop mess. Those days are gone for voice, but we're right back there again when it comes to HD video calls. However, random product researcher Fraunhofer is working on a new device to kill the lag and speed up your two-way monologues. It's basically an encoder card able to do hardware squashing of HD video via H.264 and audio via AAC, not unlike the sort of tech Skype requires for its SkypeHD-compatible video cameras. Fraunhofer's tech is also said to remove boomy room echoes and even handle network hiccups to keep you streamin' in style. The result is said to be sub-100ms lag, which would be more or less playable for a shooter. Expect more on this development soon from IFA.

    It seems like everyone is cooking up their own touch-free gesture-based control technology, just like every blogger is destined to refer to it as "Minority Report-like" or "Minority Report-esque," or "Tom Cruise-tastic!" Fraunhofer's FIT, the newest such project, has recently appeared on the YouTubes, where we must say it looks pretty darn good. Not only does it not require special gloves or markers, this thing also works in real time and can support multiple users (and multiple fingers). The researchers hope to use this for working with complex simulation data and in education, although there are some kinks to be worked out: currently elements like the reflections caused by wristwatches and the orientation of the palm confuses the system. That said, the demo is pretty rad! See for yourself after the break.

    We're glad you're using a bike helmet (and we're glad you've opted for that really scary one we first saw in 2007). You do realize, however, that the more blows to the head you receive, the less effective the headgear is, right? Researchers at Germany's Fraunhofer Institute have developed a manufacturing process that injects microcapsules containing malodorous oils into the helmet itself, causing it to stink when damaged -- alerting you that it's time to replace it (and making it difficult to try and make do with a less than safe one, at that). Indeed, the process, which a thick foil made of polypropylene to house the microcapsules, extends to other products as well, including: pressure hoses, water, and gas pipes (in which case the odor can be detected by automated "smell sensors"). As for the lids, they're still trying to decide exactly which scent to use, but we have a suggestion -- smelling salts. Seems logical, right?

  • Fraunhofer's 3D posters make your fish-based advertising really pop

    The pinnacle of 3D-based content? Glasses-free, of course, and Fraunhofer has reached that level for static images -- and it plans to use it for advertising, of course. The company is talking up its new 3D posters that rely on 250,000 lenses embedded in a grooved sheet, each lens with a 2mm diameter. The effect is said to be similar to those simple "3D" lenticular postcards and cereal boxes we've all seen, but Fraunhofer promises that improved accuracy used in manufacturing here will make the resulting images far clearer, enabling the effect to be clearly seen on these five meter posters even from across the street. That's good, because when was the last time you walked up to a billboard to get a closer look?

    Biochips -- flexible, disposable plastic circuits that "compute" via chemical reaction -- have been nearing reality for over a decade, but for obvious reasons we don't always pay attention. German research institute Fraunhofer IZM has just convinced us it's high time we did. This week, the organization announced that it's on the verge of creating a lab-on-a-chip that can diagnose deep vein thrombosis from a single drop of blood, as well as a wristband that can measure body temperature, skin moisture and electromagnetic radiation using plastic chips and sensors only micrometers thick. Impressive, yes, but the real news is the production process -- these gadgets can be printed in reels and sheets. The organization imagines the tools will be so cheap they'll be disposable; rather than wait for lab results, worried individuals will just take one out, test and toss to feel confident about their bloodwork, before hopefully going back to their normal lives.

    HYPOLED, an 18-month-old project tasked with creating OLED microdisplays for upcoming pico projectors, has just released a report of its recent progress. Among the advances is a Fraunhofer IPMS-designed all digital VGA, full color OLED microdisplay backplane with matching pico projector optics. The display measures just 0.18-mm thick and is already in prototype manufacturing. The super miniscule display is connected to a MediaBox enabling it to operate via WiFi. Fraunhofer is now expected to begin developing a prototype of the full projector, meaning that with any luck, our picos should be getting a teensy, tiny bit cooler in the near future.

    Researchers at the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz led by Prof. Dr. Reinhard Baumann have unveiled tiny, printable batteries that they hope to put into production for pennies apiece. The new battery prototype is primarily composed of a zinc anode and a manganese cathode that can be screen printed and covered with a non-printed template cover. Each mercury-free battery weighs less than one gram, and can individually produce about 1.5 volts of electricity. By placing several batteries side by side, however, up to 6 volts can be generated. The institute has already produced these little power houses in the lab, and hopes to see them into production by the end of the year. The batteries have a relatively short lifespan, making them suitable for applications such as powering greeting cards. All we can say is that this battery would have made the card we got two years ago that sang "Word Up" much, much awesomer. [Via Physorg]

    Researchers at the Fraunhofer Institute -- partnered with project HYPOLED -- have created an OLED mini projector prototype for mobile phones. Unlike many previous iterations of similar technologies, this new prototype doesn't need an additional illumination system, instead relying on a lens system to project images produced by an OLED onto a screen or wall -- making it both smaller and more energy efficient. The prototype currently displays a monochrome image with a brightness of 10,000 candelas per square meter, and color images with a brightness of about half of that. The lenses are also made of glass at this point, though cheaper and simpler plastic ones are in the works. No word on when we might see these prototypes hitting the streets in actual projector phones, though.[Via Gizmag]

  • Interactive data eyeglasses could bring the PC to your face, won't fix nearsightedness

    Leave it the mad scientists at Fraunhofer-Gesellschaft to concoct this one. Rather than just figuring out a way to read back information in one-way fashion on one's glasses (think Sixth Sense, but with eyewear), these folks are diving right in to the real stuff: bidirectional communication. In essence, their goal for the interactive data eyeglasses is to track eye movement in order to allow ones retinas to scroll through menus, flip through options and zoom in / out on a map. Obviously, a microdisplay will be necessary as well, but that's just half the battle. We'll confess -- we're still not humble enough to take our Vuzix HMD out in public, but we just might swap our Transitions™ for a set of these.[Via OLED-Display]

    At the Fraunhofer Institute in Bremen, Germany, a group of researchers, in conjunction with the German Research Center for Artificial Intelligence DFKI, is developing an underwater robot with a sense of touch. The octopus-esque robot is equipped with a strain gauge which triggers electrical resistance changes when an obstacle is encountered. The strain gauges -- which are printed onto the robot -- which are ten micrometers wide (about half the width of a human hair), are made up of atomized nanoparticles, and are extremely sensitive. The researchers intend for the robot to be able to distinguish between actual obstacles and water currents. The robot's first stop will be a public trade show at the end of May in Nuremberg, after which it will presumably make it's way to the dark depths of the sea to meet up with Captain Nemo and the giant squid.

    Oh sure, liquid cooling rigs are all the rage, but they aren't too useful within minuscule things like netbooks, MIDs and pocket projectors. The always churning minds over at Fraunhofer-Gesellschaft are already on the issue, recently conjuring up a new material designed to "efficiently dissipate heat even in devices with densely packed components and that can give increasingly miniaturized electronics a longer life." Researchers at the entity's Institute for Manufacturing Engineering and Applied Materials Research have teamed with gurus from Siemens and Plansee to create the substance as part of the EU project "ExtreMat." Unfortunately, details beyond that are few and far between, but given that demonstrations have reportedly "already been produced," we'd say it's well on its way to infiltrating things far smaller than your mind can grasp.

  • Fraunhofer's new security device turns your window into a motion detector

    The brain geniuses at Fraunhofer are back on the scene with a security device that takes the window alarm to the next level. The Vigilant window sees the ol' glass panel coated with a nanoparticle material which converts light into fluorescent radiation. When the system is switched on, a UV lamp is aimed at the window, which is outfitted with sensors along its edges. As long as the lamp is unobstructed, everything is goldie. However, if a cat burglar should come by in his trademark all-black out fit and obstruct the beam, the alarm is activated -- sending your elite security team into action. If you don't have an elite security team, perhaps you can send your T-34 to snare him in its net. Either way, it's clear they messed with the wrong folks this time. A prototype already exists, no word yet on when this will become available.[Via Oh Gizmo!]

  • Video: Fraunhofer-Gesellschaft's iPoint 3D Pong match gets heated

    After hearing that Fraunhofer-Gesellschaft was bringing its newfangled iPoint 3D setup to CeBIT, we simply had to make the 5.9 mile hike from Hall 26 to Hall 9 to check things out. As with most things that this outfit touches, iPoint 3D was also a sight to behold. Without any goofy glasses, players and onlookers alike could easily detect depth in the display, and while we're some of the toughest 3D critics you'll find, even we were taken aback at just how not-gimmicky it was. An overhead motion detecting system fed signals to a nearby computer, which then translated the hand gestures into paddle movements within the simple two player Pong game. The gals we recorded seemed to have a pretty good time with it, and if you don't believe us, just check out the winner's victory dance at the end of the clip -- it'll make your day, and that's a Billy Mays guarantee.%Gallery-46448%

    The sheer amount of technology companies are willing to throw at your car's dashboard is amazing (well, maybe not your car -- after all, you're still driving a '76 Gremlin). Taking things up a notch, the folks at Fraunhofer have developed a dash that displays your location and the surrounding area in 3D, in real time. The system uses cameras to keep track of the location of your eyes, so the depth imaging effect can be achieved without using those funny glasses. In addition to the GPS, the dashboard only displays the information that is most relevant to the driver at any time -- fuel gauge, tire pressure, route information or the title of the song can be displayed, depending on user preferences. It's only a prototype at this point -- be sure to check it out when you hit CeBIT in Hanover this March.[Via The Raw Feed]

    Granted, we've no idea what it takes to really push the efficiency level of a solar cell, but we're getting pretty bored with these incremental improvements year after year. If you'll recall, the record for solar cell efficiency sat at 40.7 percent in 2006, and that was raised to an amazing 40.8 percent last August. Today, researchers at the Fraunhofer Institute for Solar Energy Systems have announced an all new milestone: 41.1 percent efficiency. According to team head Frank Dimroth, the crew is simply "elated by this breakthrough." Meanwhile, the rest of planet Earth is suddenly depressed by the thought of perishing from old age before this data point ever breaks the big five-oh.[Via Gizmag]

    Look, we're not going to argue that those chintzy clap lamps weren't pretty sweet in their heyday. And we're also not going to put up a fuss when you assert that snap bracelets were equally adorable in the early 90s. Nostalgia aside, Fraunhofer IPMS is headed straight for the future with its latest OLED breakthrough. Reportedly, the company has devised an OLED display that can be controlled via human touch or by simply waving one's hand in front of the panel. Unlike similar applications that have come before it, there's no additional hardware needed -- and therein lies the magic. The outfit is currently showing off the design at the Plastic Electronic 2008 show, though it yet to reveal anything close to a release plan. [Via OLED-Display]

    The always-imaginative gurus at Fraunhofer-Gesellschaft never cease to amaze, and at this year's IFA, they're delivering once more. The so-called "virtual mirror" gives to-be garb buyers an accurate look at what different outfits look like on their person without requiring them to try a single thing on. Granted, shopaholics are apt to detest this thing, but anyone with better things to do than try on four sweaters to see which one makes them look fat should be completely in love. The concept here is far from new, as we've seen both virtual makeover machines and fitting room enhancers before. Still, Fraunhofer's dream of getting you suited up and out of the store in mere minutes is one we'd love to see come true. Just don't ditch the traditional stalls too soon -- we wouldn't want any kind of worldwide uprising.[Via Physorg, image courtesy of Flickr]

  • Fraunhofer takes a stab at non-exploding lithium-ion batteries

    It's hardly the only one working on making lithium-ion batteries a little less likely to blow up in your face, but the prolific folks at Fraunhofer Institute seem to think that they've come up with a solid contender for your future laptop or cellphone, and they're now set to take the wraps off it at the Hannover Messe conference later this month. The key to their solution, it seems, is the use of a non-flammable polymer electrolyte instead of the liquid electrolyte now commonly used in lithium-ion batteries. While that switch cuts down on the explosiveness, it also introduced a fair number of challenges, not the least of which is the fact that polymer becomes less conductive as it gets more solid. Fraunhofer's apparently made some significant progress on that front, however, and while they're still not completely satisfied with the conductivity, they say the batteries could be ready for commercial use in three to five years. They also, not surprisingly, see no end to the uses for 'em, saying that they could not only wind up in laptops and cellphones, but power tools, lawnmowers, and potentially even cars.[Thanks, Mademoiselle Y]

    Sure, it might look like a Viewmaster 3D from your childhood, but this here stripe projection 3D sensor from Fraunhofer IOF is so much less exciting. The concept is simple enough: the Kolibri projects a stripe pattern onto the subject, and then the two "eyes" capture slightly distinct angles of the image to compose a 3D model of the object based on the deducted geometry. The technology has been available for a while, but this is apparently the first device to cram it into such a small and portable form factor. Yeah... we'll stick with the Viewmaster.[Via About Projectors]

  • Fraunhofer says HD-ACC will make CDs "obsolete"

    Those Fraunhofer folks are nothing if not prolific, and it now looks like they're getting a little boastful as well, as evidenced by some comments reps from the group made at CES this week. As MacWorld reports, Fraunhofer IIS is not only saying that its new HD-ACC codec is "better than CD," but that it "makes CDs obsolete." That is apparently due to the codec's lossless compression of 24-bit music content, as opposed to the 16-bit, 44.1 kHz quality now found on CDs. What's more, the HD-AAC encoding process embeds a so-called "core layer" on any device that supports plain old AACs, although you'll obviously need a player with an HD-AAC decoder in order to take advantage of the fully lossless signal. Of course, some formats have a tendency to take off more quickly than others, so we'll just have to wait and see how HD-ACC plays out in the grander scheme of things.
