Not even IBM is sure where its quantum computer experiments will lead
Despite the hype and hoopla surrounding the burgeoning field of quantum computing, the technology is still in its infancy. Just a few years ago, researchers were making headlines with rudimentary machines that housed less than a dozen qubits -- the quantum version of a classical computer's binary bit. At IBM's inaugural Index Developer Conference held in San Francisco this week, the company showed off its latest prototype: a quantum computing rig housing 50 qubits, one of the most advanced machines currently in existence.
Adding a second pair of arms is as easy as putting on a backpack
There's only so much you can do with two arms and hands. That's basic science. But what if you could add extras without the need for ethically shady surgery or trading your apartment for a hovel in the shadow of a nuclear power plant? That's what researchers from Keio University and the University of Tokyo hope to achieve with their "Metalimbs" project. As the name suggests, Metalimbs are a pair of metal, robotic arms that doubles the amount of torso-extremities and worn with a backpack of sorts. And unlike thought-powered prosthetics we've seen recently, these are controlled not with your brain, but your existing limbs. Specifically, your legs and feet.
This camera can snap chemical reactions at a trillionth of a second
You know those high-speed cameras used to film mesmerizing ultra slo-mo videos? They're downright slow compared to this one developed by researchers from The University of Tokyo and Keio University in Japan. The 12-man science team has just revealed an extremely speedy camera that can take pictures of chemical reactions (in burst mode, as those are impossible to capture in a single shot) at 450 x 450 pixels. It's called the Sequentially Timed All-optical Mapping Photography or STAMP cam, and it can capture consecutive images at a rate of one per every one-trillionth of a second. To note, other high-speed cameras capture one image per every one-billionth of a second. The device is supposed to be 1,000 times faster than comparable models and has even managed to snap a picture of heat conduction (a process that takes, oh, 1/6th the speed of light) during a test.
Keio University's Kinect-based Haptic VR system lets you roll your own face flat (video)
A research team at Keio University has built a fun haptic virtual reality system that enables you to manipulate pictures with a rolling pin. A vertically mounted Kinect takes a 3D image that is then displayed on the projection surface. Using the rolling pin, the image can be rolled over and flattened as if it was dough -- with a series of motor cranks inside the implement to replicate the necessary feedback so you can feel what it'd be like to iron out your own face. It's been designed as a modern-day update to the penny-squashing machines you found in theme parks, except with slightly more grotesqueness. You can watch the face-mashing in glorious color after the break.
Keio University democratizes facial recognition technology for Avatars everywhere (video)
If you liked the look of that facial recognition technology on its way to Everquest II, but aren't so sure on your Froglok allegiance, then a Keio University group may have you covered. A project led by Associate Professor Yasue Mitsukura has developed a similar technology using just an ordinary PC and webcam. The software uses an algorithm that updates in line with the motion of the face, which the makers claim make it very fast and precise. The researchers hope that this real-time, low hardware requirement, system could find its way into the hands of amateur CG animation creators, or -- like the SOEmote solution -- into game controls. So, expect a glut of pimped-out Numa Numa remakes in the not to distant future.
Japanese researchers show off 'interactive' plants: real leaves, artificial emotions
Looking for a little more companionship from your household plants? Then a team of researchers from Keio University in Japan may have just the thing for you. They've developed a rather elaborate system that promises to lets plants react to you and display a variety of different emotions (see "anger," pictured above). Yes, that's a real plant sprouting up out of the box, which contains sensors and microphones that monitor its surroundings, as well as some actuators that are connected to the plant itself with some fine cords. Lest you worry about the safety of the plants themselves, the researchers say that they've had plants rigged up like this for nearly a year and none have wilted. Of course, there's no indication of a commercial version just yet, but you can get a glimpse of the current state of things in the video after the break courtesy of DigInfo TV.
Add-on turns a smartphone camera into a joystick (video)
One of the more irritating aspects of touchscreen gaming is almost certainly the inevitability of blocking the screen as you play -- particularly with smaller devices like smartphones. A new peripheral being developed by Keio University takes an interesting approach to the problem -- using the device to transform the gadget's camera into a three-axis joystick of sorts by detecting the movement of markings on the add-on. According to its creators, the accuracy of the joystick depends largely on the precision of the phone's hardware. Check it out in action after the break.
Pinoky makes it easier to pretend like your stuffed animals are real friends (video)
Seated above, from left to right, are Ms. Snuggleberry, Mr. Cuddlekins, and Professor Puddles. They congregated atop this egg yolk for what they thought would be another customary meeting of Mammalian Malice -- a vaguely neo-Jacobean slam poetry collective founded in the aftermath of the Crimean War. Little did they know, however, that they were walking straight into Yuta Sugiura's trap. Sugiura and his colleagues, you see, have created a toy known as Pinoky -- a small, ring-like device that wirelessly brings stuffed animals to "life," as Snuggleberry, Cuddlekins and Puddles soon discovered. Developed as part of a project at Keio University, Pinoky uses a micro controller, a Zigbee input device and a servo motor system to move an animal's extremities, with a set of photo sensors designed to measure the angle at which it bends. All you have to do is grab your favorite imaginary friend, strap a Pinoky around his limb, and use the accompanying remote controller to make him flail around like a fish on house arrest. See it for yourself, after the break.
Telesar V robot brings new meaning to escapism (video)
The esoteric art of telepresence is all about that sweetest of dreams: being somewhere you'd rather be. So far, though, it's hardly teleported much beyond our head movements and kisses. What we really need is a fully-fledged avatar that can also feed sensory information back to us -- and that's exactly what the Telesar V claims to be. The user dons a pair of VR goggles that control the robot's head and see through its eyes. A pair of gloves not only control the Telesar's hands, but also transmit force and temperature data back from its sensors. Drag yourself away from that violent BF3 simulator and check out the smoochiness after the break. (And yes, the inventor's surname is just about perfect.)
RePro3D is a 'touchable' 3D interface that lets you poke pixies (video)
The illusion of 3D is kind of ruined the moment you reach out and try and grab whatever silly thing is supposed to be protruding from the screen. Researchers at Keio University in Tokyo have started to figure out a solution to the problem, and are calling their system RePro3D. By combining a glasses-free 3D display with an infrared tactile interface, they are able to create a holographic model that responds when "touched." The next step for the team is to provide feedback via a wearable device, adding the sensation of touch to the already impressive illusion of interactivity. We do have our concerns about the researcher's motives however. One of the creators, Keitaro Shimizu, told DigInfo, "there are many attractive characters in animations and games, but since those characters only exist within the screen, it feels a little lonely..." We guess getting a girlfriend is out of the question. Check out the video after the break.
Japanese scientists create giant metal cilium, relief for Voltron's giant metal lungs (video)
Why would a group of researchers develop a table full of rods that mimic the movements of microscopic hairs? It's a fair question, and Keio University's Yusuke Kamiyama certainly doesn't offer up much in the way of real world applications for such technology. He is, however, happy to demonstrate the cool functionality of the metallic cilium, which appear to drift around as though underwater, until coming into contact with an external stimuli. The rods react to touch by congregating near the area of contact, with movements executed by biometal rods that communicate with an external PC. Scientists hope that research from the project will be useful at some point, but in the meantime, at least we know where to turn if we get a major mucus blockage. Video after the break.
TEROOS robotic avatar gives your long-distance girlfriend a tiny, googly-eyed face (video)
Do you pine for animatronic eyes and robots that whisper sweet nothings in your ear? Well, geeks with distant girlfriends rejoice, because TEROOS, the shoulder-mounted, remotely-controlled telepresence avatar has arrived. Created by researchers from Keio University in Japan, the little bot has a camera and mic so far away friends can see and hear what you do, while a directional speaker keeps your conversations private. Communication's courtesy of Skype, while some custom code lets users control the device's six-axis articulating head. It's not an independent system, however, as it relies upon a smartphone to relay commands from a PC to the avatar through Bluetooth. Users can also change the bot's facial expressions thanks to a couple of googly eyes and mechanical eyelids, though it doesn't have quite the emotional range of other androids from the land of the rising sun. Intrigued? Check the vid after the break.
Fragrance Jet II receives video demonstration, still looks like a terrible idea (video)
Ah, those zany Keio University researchers trying to recreate Smell-O-Vision, do you want to know what they're up to these days? They're still trying, of course, but now they've taken the opportunity to demonstrate their hardware -- which uses basic inkjet printer tech to fire off very short bursts of fragrance -- to tech lovers in Japan while still tweaking and refining it. Primarily aimed at helping healthcare professionals in assessing a patient's sense of smell, the Fragrance Jet II has a high degree of control granularity, permitting the varying of both intensity and duration of a scent, which in turn can provide a very accurate measurement of a given person's olfactory acuity. A mobile prototype has also been trotted out (pictured above), hinting at the possibility of eventually shrinking these modules to fit inside cellphones and thus leading us to an awesome future of customizable "incoming call fragrances." Awesome indeed. Video after the break.
Augmented reality TagCandy creates a virtual taste explosion (video)
The majority of augmented reality applications these days may be visual ones, but that's hardly the only type of augmented reality possible, as fully evidenced by this so-called TagCandy device built by Yasuaki Kakehi of Keio University. As you can see above, it consists of a rather large base that accommodates a regular lollipop, which not only makes it easy to hold the candy, but uses bone-conduction technology to produce different sounds ranging from fizzy soda to fireworks. Of course, it is just a concept, and still something of a work in progress -- future possibilities apparently include the ability to detect biting in addition to sucking, and the ability to buy and share different "sensations" on the internet. Head on past the break to check it out on video.
Keio University developing 'olfactory printer,' AromaRama due for a resurgence
We're not entirely sure why people keep trying to bring back Smell-O-Vision, although Keio University's success in printing scents using a modified printer gives us hope that this sort of thing might someday be somewhat feasible -- and useful. It works by using an off-the-shelf Canon printer that's been given a "scent jet," Kenichi Okada told New Scientist. "We are using the ink-jet printer's ability to eject tiny pulses of material to achieve precise control." The scent dissipates quickly, after one or two human breaths. And while specific scents can be printed, there is as of yet no way to build a general purpose device. According to the University of Glasgow's Stephen Brewster: "We don't yet know how to synthesize all the scents we want. There is no red-green-blue for smell -- there are thousands of components needed." That's OK with us. In our experience, it's usually better that people keep their smells to themselves.
Twinkle augmented reality interface promises to make your world a platformer
Augmented reality demonstrations may be pretty common these days, but this so-called "Twinkle" interface developed by some researchers Tokyo University and Keio University takes a different enough approach to still turn a few heads. That's done thanks to the combination of a pico projector and a camera, the former of which projects a character onto any surface, while the latter is used along with some image processing software to identify objects the character can interact with. That's further backed up by an accelerometer that detects movements the camera can't, and the researchers say that the system can not only recognize specific objects like the ones on the board pictured above, but everyday objects as well -- letting you put your LittleBigPlanet skills to use on your desk, for instance.

Keio University and Toshiba ready tiny 1TB SSDs for 2012
Japan's Keio University claims to have developed, in conjunction with Toshiba, the technology to shrink the size of SSDs by a spectacular 90 percent while also cutting energy consumption by 70 percent. If that's not enough mind-boggling numbers for you, the final product of this partnership is expected to yield 1TB drives with 2Gbps throughput. The details of this are still somewhat unclear, but we're told researchers stacked 128 NAND flash chips atop one another, with the breakthrough being in the way they communicate -- using short-range magnetic signals --- which results in less wiring complexity and reduced production costs. We'll take some convincing to believe they can really put these to practical use by 2012 as promised, but if they do make it to any sort of commercial launch, you can bet we'll be queuing up through the night to get one.

Walky robot understands iPhone gestures, football fanaticism (video)
Hey there sailor, we imagine you've been doing your fair share of button mashing what with a certain new bit of software out and about, but how would you like a whole new control paradigm? Taking up Steve Jobs' war on buttons, a group of grad students at Japan's Keio University have put together a comprehensive robot control interface that relies solely on finger swipes, taps, and presses. By employing the iPhone's built-in accelerometer and multitouch screen, the robot can replicate a humanistic walking motion, perform sidesteps and, when called upon, kick a football with gusto and presumed passion. Your destination is just past the break, where the video demo awaits. [Via HDBlog.it]
Digital Rosetta Stone memory could last a thousand years
The race for bigger and better memory continues apace, it seems. It was only a week or two ago that we caught wind of the work that scientists in Berkeley were doing with nanotubes and thousand-year-plus memory lifespans, and now it looks like a group of researchers in Japan have made some headway using an electron-beam direct-writing technique that utilizes semiconductor devices that can keep data intact for a thousand years, so long as humidity is kept at 2% or less. The prototype Digital Rosetta Stone, developed by Keio University, Kyoto University, and Sharp, has a storage capacity of 2.5TB and a max transmission speed of 150Mbps. Of course, there's no telling if or when this will become a reality, so if you want to ensure that your adolescent poetry lasts for the next thousand years, you'd better print out your MySpace blog and have it carved in granite.[Via TechShout]
Team hopes to build 200 eight-wheeled Eliica electric cars
Dr. Hiroshi Shimizu of Tokyo's Keio University has been working on his Eliica eight-wheeled electric car since 2003, but the Japanese government's interest in fuel-efficient vehicles has rekindled his efforts, and he's currently, um... on a roll. The current Eliicas, of which there are currently two, run on lithium-ion batteries and each wheel is driven by a 60 kilowatt engine. The auto's got a top speed of 230 miles per hour, and Shimizu's group of engineering students eventually hope to reach 250 miles per hour with new models. The team is currently trying to raise a bunch of money to build 200 of these, which cost somewhere in the realm of $255,000 each. We wish them luck in their endeavors, but can't imagine Syd Mead's going to be pleased there's another futuristic-hearse designer entering the market.[Via AutoblogGreen]
