UCLA creates portable microscope that uses holograms, not lenses
Instead of lugging a heavy microscope into the field, doctors and nurses in remote regions may have a more portable choice -- a lightweight microscope that replaces lenses with holograms. Researchers at UCLA announced a prototype dual-mode microscope that's lightweight, costs between $50 and $100 to produce and is similar in size to a banana. Like a hologram that uses interfering rays to create an image, this device shines light on a sample where its sensor chip (apparently also found in iPhones and BlackBerrys) and a cloud-based software program analyze the interference pattern and reconstruct an image of the sample. Since it's dual-mode, both large samples and small samples can be analyzed through processes called "transmission" and "reflection," and doctors could potentially use their laptops or smartphones to access the images remotely. Although still considered a prototype, researchers think the development has the opportunity to revolutionize health care by allowing doctors to test things like water, blood and food.

Airbus' plane of the future will harvest energy from passengers, earn Agent Smith's approval (video)
Airbus has been consulting its crystal ball recently and its findings have now been shared with the world in the shape of a new concept plane. Looking entirely detached from the economic and physical realities we know today, this futuristic people carrier includes auto-morphing seats that adjust to your size and shape and also harvest excess heat you produce. How is this achieved? Smart materials is all we're told, leaving us to use our imagination to fill in the gaping blanks. Eschewing the usual class system, this Airbus concept instead offers three functionally distinct areas: a Smart Tech Zone at the back is the closest to what we're used to today, an Interaction Zone in the middle uses holograms to help you relax or conduct some mission-critical meetings in flight, and a Vitalising Zone up front is where more "bio-morphing" seats will provide you with massage or acupuncture treatments. The ceiling in that front part of the plane can also be turned transparent, letting you soak up the panorama (and get a good tan while you're at it). You can see and hear more about it in the videos after the break.
DARPA's next-gen wearable display: augmented-reality, holographic sunglasses
The US military seems to adore the idea of wearable displays, hence its continued efforts to make them a reality. We know it seems like just yesterday that DARPA tapped Lockheed Martin to build low-power, lightweight augmented-reality eyewear, and it was actually four full years ago when the wild and wonderous dream was to craft HMDs as small and light as "high-fashion sunglasses." Well, that dream lives on, this time with holograms: the lenscrafters at Vuzix just received a cool million to develop goggles that holographically overlay battlefield data on the wearer's vision. It all sounds very Dead Space (or, you know, like a Top Secret version of Recon-Zeal's Transcend goggles), promising realtime analysis of anything within sight. The company believes the finished product will be no more than 3mm thick and completely transparent when turned off. If all goes well, expect this to trickle down to consumers in short order; soon you'll have full "situational awareness" -- including relationship status -- of that mysterious stranger you've been eyeballing from across the room.
British airports now beaming holographic security agents (video)
They've brought you presidential election coverage and promoted worldwide access to PCs, and now they're telling you to take off your belt and throw out your hairspray. Starting today, London Luton and Manchester airports will beam in images of holographic agents to prep passengers for the security line. Holly and Graham -- you heard right -- and Manchester's Julie and John are meant to cut queues, as well as human inconsistency. According to Luton's Glyn Jones, "Holly and Graham are not going to have a hangover; they're not going to have a row with their partner the night before." Just what we need: an army of holographic squares taking our jobs and making us all look a drunken mess in comparison. Thanks, technology. Update: So it appears these aren't traditional holograms -- they're actually huge sheets of glass that are cut out in the shape of people, with the projection beamed on them. It's the same tech that Gorillaz use on stage, made by a company called Musion. Check out another video where the camera moves around the side.
ZScape 3D holographic prints take maps to the next dimension, sans spectacles
As the video above shows, Zebra Imaging's so called ZScape prints pull off some pretty amazing 3D visual effects despite being based on old school hologram technology. These prints are made using a variety of 3D data sources -- think AutoCad and the like -- that are then rendered as thousands of holographic elements by recording laser light onto a single film-based material. The resulting images are easily viewed without glasses or spinning mirrors, and just require a run-of-the-mill halogen or LED light source to reveal 360-degree, full color representations -- akin to what a physical model might look like. Fancier versions can also be made using overlays and layering techniques to show more information. To date, over 8,000 ZScapes have already been developed for the US military, but surprisingly their prices range between $1,500 for a 12- x 18-inch version to $3,500 for the largest 2- x 3-foot size, making them relatively obtainable for those not on Defense Department tabs. If the video of Seattle pulling an Inception above didn't impress you enough, be sure to check another embedded video after the break.
Dynamic 3D holograms can now refresh every two seconds, save galaxies in their spare time
Perhaps the biggest challenge in making holograms usable on a daily basis -- aside from having to film your subject with a million trillion cameras -- is in getting their refresh rates up to the levels we're used to with "normal" two-dimensional video. We're still a fair way away from those magical 30fps, but the University of Arizona is touting a heretofore unheard of redraw rate of once every two seconds. This is a major advance from their first dynamic holograms demonstrated two years ago, which required minutes to swap over to a new image. The current prototype is built on a 10-inch photorefractive polymer screen, with lasers beaming information onto it, though 17-inch versions are also being tested. Another present limitation is that the hologram displayed can only be of one color, but that is also subject to the continuing labors of the UA researchers, who foresee no major hurdles preventing them from eventually cobbling together full-color, fast-refreshing, and fully realized 3D holograms. Now that'd be 3D television we can all get behind. Or in front of, depending on the viewing angle we want.
NICT's fVisiOn makes you see immaterial bunnies (video)
Japan's National Institute of Information and Communications Technology (NICT) has been chasing holographic damsels in distress for as long as we can remember, and honestly, the technology's still not quite there, but the team that brought us the gCubik has managed to create a low-res 3D hologram table that impresses anyhow. Using an twist on the famous optical illusion toys that use convex mirrors to make objects appear to float in the air, NICT hits a specially-designed optical filter cone with the light from 96 pico projectors. The result is a series of familiar-looking rabbits, teapots and the occasional rubber duck standing five centimeters high and visible through 120 degrees, a good sight better than the two-degree radius afforded them by the original technology. The best part is there's no case enclosing these creations, unlike competing ideas, so we'll eventually see 360-degree tables where your fingers can frolic alongside the ethereal leporidae. Watch the lead researcher demo a prototype after the break.
World Science Festival kicks off June 2nd in NYC
If you're in the New York City area during the upcoming week, you really might want to think about trying to score yourself some tix to the World Science Festival. We've never been ourselves, and we have to say that our interest -- based on the description of the events -- is seriously piqued. The Festival was started Brian Greene (the physicist, not the guy from 90210) and his wife, and will run from June 2nd to the 6th. It will kick off with a gala event featuring Stephen Hawking, and will host a wide variety of talks over the week, covering topics like the science of sound, the science of Star Trek, and whether or not it's possible that we're all holograms. We're hoping to try to hit at least one of these events ourselves (though we do have a busy week ahead), but we suggest you check out the source link for full details yourself.
HoloToy: An amazing 3D app for iPhone and iPad
We've looked at a lot of 3D apps before, but I believe that HoloToy (US$0.99) is really something special. If you have an iPhone, iPod touch, or iPad, you should download it right now. I don't think you'll find a better 3D app in the whole store. HoloToy uses anamorphosis perspective projection to do its magic. This means that you won't have to wear those cardboard anaglyph (usually red and cyan) glasses; aside from being annoying, they kill the brightness and reduce colors to a muddy shade of beige. All you need to do is look at it and twist and turn your device to see the effects. It's an interactive app, and by making wonderful use of the built-in accelerometer, you can do a do a variety of things, including moving around a HoloBot robot and even playing a few games. The process used prevents images from appearing in front of the screen, so what you get is a five sided box, with the screen being a clear wall that you look into. Twisting, turning, and tapping on the screen lets you interact with all of the 3D images. The intention of the app was to start with a few sample images and add others every week or so, based on reader feedback. In fact, just today an update was released adding a customizable aquarium option. You can see the progression of the app as the new images have been released; the app started as a bunch of planets suspended in space that you can spin around by swiping. The distance between the planets and the back wall is apparent, and there is a white box on the back wall whose corners you can see by twisting and turning the screen. The depth effects get better with the next two non-interactive modules, an impossible triangle and two differently sized boxes.
Holocube Touch demonstrated on video, no glasses required
The original Holocube was already fairly impressive as it was, but it looks like the folks behind it have now managed to do one better with their new Holocube Touch. While complete details on this one are still a bit light, it apparently uses the same type of projection system as the original, with some added touch capabilities to let you interact with the holograms -- although not quite to the same degree as some other systems. As if that wasn't enough, they're also now apparently hard at work on 42-inch Holocube, but there doesn't seem to be an ETA on it just yet. Head on past the break for a glimpse of this one in action.
Holograms: potential and confusion for $1.99
I have been a fan of 3D ever since I found a 3D horror comic book in an old flea market when I was a kid. The anaglyph red/blue glasses made the black and white comic images jump off the page. It really hooked me, and since then I've seen most all of the 3D movies made, ranging from The Creature From the Black Lagoon, to Kiss Me Kate, to Hitchcock's Dial M for Murder, in the early days, to the pretty darned amazing IMAX 3D Across the Sea of Time, the first one that really blew me away. With recent releases using the Real-D process, films are using 3D as a storytelling device instead of a gimmick - as evidenced in both Coraline and Up. Now 3D is making a huge resurgence. It's hard to find a CGI animated film that's not in 3D. The market is getting ready to explode with live action 3D films from big name directors, like the upcoming Avatar, directed by James Cameron, and Tim Burton's Alice in Wonderland. Dreamworks states that all it's animated product will be in 3D from now on and Pixar is redoing the two Toy Story pictures for 3D before the release of Toy Story 3, also in 3D. I spent many visits exploring the old Museum of Holography in lower New York City standing, amazed, in front of, and walking around seemingly impossible sights. I'm by nature a gimmick nut and holography is the most impressive visual manipulation I've ever come across. I was very excited to find the Holograms app by Mach Kobayashi. Even though the app's 3D effect is not actually holography, the demo video looked amazing and the results are impressive - but getting it to work is less easy.
Touchable Holography uses Wiimotes to add touch to holograms
Researchers from The University of Tokyo have demoed a touchable hologram at Siggraph 2009. The project, called Touchable Holography, involves the use of Wiimotes placed above the display to track hand motion, and an airborne ultrasound tactile display created in the university's lab to create the sensation of touch. The result is a holographic image that produces tactile feedback without any actual touching, and without degrading the image itself. Check out the video after the break for a fuller, more stunning explanation. [Thanks, Adam]
Infosys develops 3D cellphone cameras, projectors
We've seen a couple handheld 3D devices, but Infosys just announced that developed a chipset capable of capturing and projecting 3D holograms from ordinary cellphones, and that it hopes to take the tech mainstream by 2010. The system captures a series of 2D images from normal cameras and uses them to develop 3D holograms, projecting received images using a laser projector and micro optical elements. Infosys also had a patent granted on the system required to transmit 3D data over normal telecom networks without clogging them up -- the data is transmitted unprocessed, and the chipsets at either end do the heavy lifting. There's no word on what devices this stuff might appear in, but we're wondering what that laser system is supposed to project onto -- or if we'll have to take up smoking to get our 3D on.[Thanks, Bucky]
Holographic Bill Gates terrorizes Kuala Lumpur tech conference
See that 15-foot beam of glowing manhood? That's Bill Gates. While cohort Steve Ballmer was being pelted with eggs by angry Hungarians, Microsoft Chairman Gates was making a virtual appearance at the World Congress on Information Technology 2008 in Kuala Lumpur. The crowd cheered -- or screamed in terror -- as the giant 4.6-meter holographic specter assured them that technology is, in fact, the future. Said the chairman, "There are one billion people who have a personal computer each but there are five billion others who don't. Microsoft also wants to reach these people." We're hoping that Bill has recorded several hundred holographic speeches and will continue to grace conventions' presences for years, and years, and years to come.[Thanks, alma]
Get your stealth on with Global Agenda
Or, maybe not. Global Agenda is an upcoming title by Hi-Rez Studios that calls itself 'spy-fi'; puzzle that one out, go ahead, we'll wait. Purportedly espousing a game system of tactical espionage, the gameplay video available seems more like Halo than Splinter Cell. Not that there's anything wrong with that.Using the Unreal Engine 3, everything looks nice and moves smoothly. Other features of the game include racing for advanced technology before other players receive it; capturing and holding strategic locations; and special tech like stealth suits, holographic disguises, and remote control robots. This shows promise, and we'll keep our ear to the ground -- or at least, our sonic wavelength remote analyzer.
