Watch Samsung VR's latest scripted series this weekend
Assuming you still have a phone to slot into your Gear VR, you'll have something new to watch this weekend. Invisible is the latest scripted series on the Samsung VR platform, and is helmed by Edge of Tomorrow and The Bourne Identity director, Doug Liman. The way Wired describes it, Invisible sounds pretty cool. The five-episode series follows the lives of an ultra-rich, but reclusive family with its hands in just about everything. The reason for living in secrecy? Well, as you might be able to guess from the show's name, certain family members can disappear in plain sight.
Invisibility 'cloak' hides objects by making them seem flat
Humanity is still some distance away from a real, honest-to-goodness invisibility cloak, but British scientists are that much closer to making it practical. They've developed a coating that uses graded refractive index nanocomposite materials (just rolls off the tongue, really) to reduce an object's electromagnetic signature. Ultimately, it makes curved surfaces seem flat -- electromagnetic waves leave almost as if there were no object at all.
Scientists make an invisibility cloak using off-the-shelf optical lenses
Most invisibility cloaks require fairly exotic technology to work, such as fiber optics or light-altering metamaterials. That's not very practical, especially since the illusion still tends to break when you move. The University of Rochester may have a far more realistic solution, however -- it has developed a cloak that only needs run of the mill optical lenses to hide objects from view. The system really boils down to clever math. By positioning two pairs of lenses in the right order, researchers can bend light in a way that hides almost everything you put in the middle of this arrangement. The approach scales up with the size of the glass, and it works at angles of 15 degrees or more; you don't need to look head-on to see the effect.
Latest Apple patents include "invisible" touch controls
Apple recently filed a patent that makes touch controls disappear -- literally. The patent (No. 8,303,151) is for something called "microperforation illumination," and while the name is catchy, the technology is actually rather complex. First you pick a non-display surface of a device like a laptop. For this example, let's just say the top of the laptop's lid. Then, using microperforations in the surface itself, you pass light through the material, making a shape appear. Combining this idea with touch controls means you could soon have "invisible" buttons that appear when in use, but disappear promptly afterwards. But the patent goes beyond just the idea of invisible controls. There is also the mention of varying sizes and shapes of microperforation, and even tiny lenses that could control the flow of light from one side to the other. However, as with all patents that make us raise an inquisitive eyebrow, there's no clear indication of what product, if any, might incorporate this rather interesting feature. [Via: AppleInsider]
Invisible's 'The New Obsolete' showcases self-constructed instruments, touts a typewriter-driven piano (video)
If you're hip to repurposing old tech for new inventions, Invisible is right up your alley. The Greensboro-based unit calls themselves a "mechanical music museum" and "a reverse engineered folk science daydream" when describing their elaborate set of sound-making contraptions and recycled video equipment. The outfit's effort The New Obsolete was part of the Moogfest happenings this weekend, and our curiosity was immediately piqued. This particular performance is labeled as "an exploded view of the strange romance between humans and technology." Among all of the self-constructed instruments is the Selectric Piano: a typewriter that uses both computer and piano parts to control a keyboard. Each keystroke by the typist corresponds to a note added to collective soundscape and a mounted video camera allows the audience to keep tabs on the textual component. The project also showcases an object known as Elsewhere's Roof. The device controls a set of drum and percussion tools with water dropping into a few rather hi-tech Mason jars. In addition to arsenal of noise makers, multi-channel video and library of collected audio (via tape decks and turntables, of course) rounds out the lot. We were able to catch one of the stellar showings, so hit the gallery below for a look at the wares while a snippet of the action awaits beyond the break.
Don't mind the zero-emissions Mercedes fuel-cell car behind the invisible curtain (eyes-on video)
Mercedes wanted to make a dramatic statement about how its new B-Class F-Cell car passes through the environment without leaving a trace, so it placed it behind an invisible LED curtain. We wanted to (not?) see that for ourselves at the Paris Auto Show, so took a quick tour of the magic LED cloak and the technology behind it. It doesn't work quite as well in a show hall as it did when we first saw it in its natural habitat, but the system was still a fun way to show off Merc's green ambitions. It works by passing video from behind the car taken with a Sony video camera through a laptop to a 200 x 300 resolution LED curtain. That makes the car blend in with its background, which is what such a car would do in the real world as far as its emissions go -- apart from a little water, of course. See the video below for the complete technical explanation.
Researchers working on thermal cloak, Predators trill their disapproval
Slathering yourself with mud to avoid head-hunting aliens is great and all, but it ain't exactly the paragon of good personal hygiene. Fortunately, researchers have concocted a cleaner and less cakey defense against Predators that's more likely to be mom approved. Fresh on the heels of the microwave invisibility project at the University of Texas at Austin, French researchers have found a way to make a cloak that can hide a subject from thermal imaging devices. The concept uses alternating materials with varying rates of diffusion to move heat around and create a thermally invisible region. Conversely, the technique can be used to concentrate heat in one spot so it gets hot rapidly. Although it doesn't quite have the wow factor of Cornell's invisibility project, the thermal research may prove to be more practical because it also can be used to manage heat and improve cooling in components such as computer chips. Of course, the question now is, can it be used to cloak an entire tank?
Mercedes slaps sheet of LEDs on the side of an F-Cell, turns car into a chameleon
It's not often that folks want to hide the fact that they're driving a Mercedes, what with plenty of them being among of the finest motorcars on the road. However, as part of a marketing plan to call attention to its zero-emissions F-Cell model, the German marque swathed a side of one in LEDs to give it the ultimate in camouflage. You see, in addition to that makeshift display, a Canon 5D Mark II was mounted on the other side of the car so that video of its surroundings could be shown on the LED bodywork -- rendering the car all but invisible to onlookers, as long as they're staring at the left side, of course. Go ahead, head on down to see the magic of digital camo for yourself in the video after the break.
Cornell scientists perform optical illusion, herald invisibility through bending of light (video)
Taken at face value, you'd almost think that Cornell scientists had successfully bent the fabric of time. With gobs of fiber optics at their disposal, the researchers have devised a method to distort light in a way that makes events in time undetectable to observers. Initial success in this Pentagon-backed invisibility project has cloaked an event for 40 trillionths of a second, leading Cornell scientists to tout, "You kind of create a hole in time where an event takes place. You just don't know that anything ever happened." The feat is performed by separating light into more fundamental wavelengths, first by slowing the red and speeding the blue. A resultant gap forms in the beam, which leaves a small window for subterfuge. Then, as the light passes through another set of fibers -- which slow the blue and speed the red -- light reaches the observer as if no disturbance had taken place at all. While the brilliant researchers ultimately imagine art thieves being able to pass undetected through museums with this method, the immediate challenge will be in prolonging the light gap. This could prove frustrating, however, due to the scattering and dispersion effects of light. As Cornell scientists dream of their ultimate heist, visual learners will most certainly want to check the video after the break.
Invisible iPhone prototype puts the 'hand' back in 'handset' (video)
Not too long ago, the invisible iPhone was nothing more than satirical fodder for the Onion. Now, Patrick Baudisch and his team of researchers at the Hasso-Plattner Institute have moved closer to making it a reality, with a new interface that can essentially transfer an iPhone touchscreen to the palm of your hand. The device involves an Xbox-like depth camera, mounted on a tripod, that can register the movements of a person's finger across his or her palm. Special software then determines the actions these gestures would execute on a user's iPhone, before transmitting the commands to a physical phone, via WiFi radio. Unlike MIT's motion-based "sixth sense" interface, Baudisch's imaginary phone doesn't require users to learn a new dictionary of gestures, but relies solely on the muscle memory that so many smartphone users have developed. During their research, Baudisch and his colleagues found that iPhone owners could accurately determine the position of two-thirds of their apps on their palms, without even looking at their device. At the moment, the prototype still involves plenty of bulky equipment, but Baudisch hopes to eventually incorporate a smaller camera that users could wear more comfortably -- allowing them to answer their imaginary phones while doing the dishes and to spend hours chatting with their imaginary friends. Head past the break to see the prototype in action.
Unclutter your Dropbox (or any folder) with Cloak
The good thing about iOS text editors and other programs which can sync with Dropbox is that you don't have to use iTunes to back up the documents that you edit on your iPad or iPhone/iPod touch. The bad thing is that almost all of them save their files in a specific named folder in your Dropbox. This can lead to a lot of folders that you probably never use on your Mac, but end up looking at anytime you open your Dropbox. OS X gives you a way to hide those folders, but it usually involves the use of a command line utility called SetFile, which isn't included with Mac OS X unless you also install the developer tools. That's where Cloak (free, 611 KB .zip download) comes in. Cloak will let you hide or show any file, either by renaming the file to start with a period, or by setting the "Invisible" Finder Attribute. Renaming the file will cause problems with the aforementioned Dropbox syncing, so you want to use the Invisible Finder Attribute. Read on for the nitty gritty...
Kinect now offers a stealth mode, courtesy of optical camouflage hack (video)
You've seen so many Kinect hacks by now that you probably think you know them all -- but wait, have you seen one that makes you look like Predator when he's busy predatorizing the populace? Or one that lets you reenact your favorite Metal Gear Solid scenes with Snake's camo turned on? Yup, a Japanese coder by the name of Takayuki Fukatsu has exploited the versatile openFrameworks to give Kinect a mode where it tracks your movement and position, but turns the dull details of your visage into an almost perfectly transparent outline. Of course, you're not actually transparent, it looks to be just the system skinning an image of the background onto the contours of your body in real time, but man, it sure is cool to look at. You can do so for yourself with the video after the break.
Entelligence: Putting a spotlight on the invisible
Entelligence is a column by technology strategist and author Michael Gartenberg, a man whose desire for a delicious cup of coffee and a quality New York bagel is dwarfed only by his passion for tech. In these articles, he'll explore where our industry is and where it's going -- on both micro and macro levels -- with the unique wit and insight only he can provide. When Apple refreshed the latest version of the iPod nano, the combination of the square form factor, touch display, clip and cool clock app made me think it would make a great watch. I was not alone. I've already seen a number of vendors scrambling to create straps and wrist cases for the nano. While Apple stopped well short of calling it a watch replacement, there's no doubt Cupertino will be looking carefully to see if there's an iWatch in your future. From Microsoft's Smart Personal Object Technology devices to watches that ran Palm OS, vendors have tried and failed to push high-tech watches every few years. I personally think the watch space and the larger invisible space hasn't been exploited properly beyond the core feature of telling time. Here's why.
Invisibility cloak upgraded to bend infrared light, not to mention our minds
The fabled cloak of invisibility was once considered impossible for modern science, chilling out with perpetual motion up in the clouds, but these days scientists are tilting at blurry windmills with a modicum of success several times a year. The latest advance in theory comes to us from Michigan Tech, which says it can now cloak objects in the infrared spectrum. Previous attempts using metallic metamaterials could only bend microwave radiation, the study claims, but using tiny resonators made of chalcogenide glass arranged in spokes around the object (see diagram at left) researcher Elena Semouchkina and colleagues successfully hid a simulated metal cylinder from 3.5 terahertz waves. While it's hard to say when we might see similar solutions for visible light, even a practical application of infrared cloaking could put your night vision goggles to shame, or perhaps block covert objects from being detected by those newfangled terahertz x-rays.
Apple applies for 'disappearing button' patent
You know that little sleep indicator light on the front of your new MacBook Pro -- the one that simply disappears when your notebook is wide awake? Apple wants to do that for buttons, too. Cupertino's latest patent application is for pressure-sensitive, capacitive touchscreen materials it could build right into the surface of its aluminum-clad devices, and identify with laser-cut, micro-perforated holes that let light shine from within. According to the filing, the technology could potentially be used to eliminate existing buttons in favor of a smooth, solid slab, and / or integrate new ones into surfaces that weren't previously considered for use. Engineers imagine light-up controls on a laptop's lid that could be used while closed for things like USB charging and media playback, and local heat and sound sensors that selectively light up interface opportunities when users are in close proximity. Not bad, Apple. As long as you let us keep our nice, springy keyboards, we're all for revolutionizing the rest of modern input.
3D invisibility cloak fashioned out of metamaterials
Those HDTV manufacturers did tell us that 3D was going to be everywhere this year, didn't they? Keeping up with the times, scientists investigating potential methods for rendering physical objects invisible to the human eye have now moved to the full three-dimensional realm. The Karlsruhe Institute of Technology has developed a photonic metamaterial that can make things disappear when viewed from all angles, advancing from previous light refraction methods that only worked in 2D. It sounds similar to what Berkeley researchers developed not too long ago, and just like Berkeley's findings, this is a method that's still at a very early stage of development and can only cover one micrometer-tall bumps. Theoretically unlimited, the so-called carpet cloak could eventually be expanded to "hide a house," but then who's to say we'll even be living in houses by that time?
Yamaha's 1mm-thick prototype speaker is made from cloth, highly directional (video)
We've already heard first-hand how Yamaha can make surround sound emerge from a single soundbar, and now the outfit's wowing again here at CEATEC. It's latest aural innovation was tucked quietly away within its booth, disguised as an advertorial for the show itself. Essentially, the banner you're peering at above is a one millimeter thick speaker that's made from cloth, and it definitely has the potential to revolution billboards and possibly even portable media devices. As you can clearly hear in the video just past the break, the flat sound waves emitted from the cloth cannot be heard unless you're standing directly in front of it; even separate audio files playing back just a few feet away didn't overlap with what we heard coming directly at us. There's no telling if Yamaha will ever take this public, but if it does, there are about forty billion ad agencies in the greater New York area that would like to speak to it.
Miruko wearable gaming eyeball robot turns the creep factor up significantly
Miruko is the creepiest gaming device we've seen in a while -- but it's also downright awesome. A robotic interface boasting WiFi and a built-in camera, it's designed to be worn and used in augmented reality, real life gaming situations, able to detect things -- like monsters -- that are invisible to the human eye. Once the robot detects the presence of said monster (or zombie), it fixes its gaze on the object, allowing the gamer to follow its line of sight and then.. you know, destroy it -- using an iPhone camera. It's also capable of locating and locking in on specific objects and faces, making it really useful in hunting down whatever imaginary creatures that have been following you lately. Check the coolness in the video after the break, but keep in mind -- we've been able to see the invisible monsters all along.[Via Pink Tentacle]
Video: Emo Labs' invisible speakers visibly demonstrated
Emo Labs is out on a crusade to unify audio and video into one cohesive, delectable whole. If you'll recall, the company's Edge Motion invisible speaker tech relies on implanting a clear membrane atop display panels, which is then vibrated by piezoelectric actuators to generate stereo audio. We've grabbed a couple of vids of it in action to whet your appetite, and while there's still no word on when, plans are afoot to embed the technology into LCDs, laptops, mobiles and even handheld gaming devices. Dance past the break to hear, and maybe even see, for yourself. [Via eCoustics]
