Everyone could soon have the powers of Doctor Octopus
Doctor Otto Octavius may have been a power-mad scientist bent on world domination and the utter ruin of his nemesis, Spider-Man, but the guy had some surprisingly cogent thoughts on prosthetics development. And although mind-controlled supernumerary robotic limbs like Doc Oc's still only exist in the realm of the Marvel Universe, researchers here in reality are getting pretty darn close to creating their own. And in the near future, we'll be strapping on extra appendages whenever we need a helping hand -- or supplemental third thumb.
The Morning After: Thursday, November 17, 2016
We put the 4K-ready Chromecast to the test, saw increasingly less snow around the US, and gawp at the first hybrid Mini -- as well as a whole bunch of new cars coming out of the LA Auto Show. There's also the discovery of a "Watch Dogs 2" character that has fully rendered sex organs for no apparent reason whatsoever. Not just another Thursday.
Researchers create a virtual screen with touchable objects
A team from the University of Tokyo is putting their own spin on a touchscreen. By combining an infrared sensor with ultrasound technology, the group of researches have managed to design a virtual display that's as thin as air and can let you feel every object you're touching. Dubbed HaptoMime, the project uses a reflective surface to give you that physically tangible feeling, while a change in ultrasonic pressure make it possible to create a number of different sensations -- say you're playing a digital keyboard (like the one pictured above), the feedback from it isn't the same you get with other type of applications. Check out the HaptoMime holographic screen in action after the break.
University of Tokyo's fast-tracking camera system could revolutionize sports coverage (video)
Researchers at the University of Tokyo's Ishikawa Oku Lab have been hard at work on a camera system that can track fast moving objects incredibly well, and the technology may change the way sports like baseball and soccer are televised. Recently, the team building the system has entered the next phase of testing: taking it outside, to see if will perform as well as it has in a lab setting. If all goes according to plan, they expect it'll be ready for broadcast use in roughly two years. Demos of the tech are pretty impressive, as you can see in the video below showing the (warning: not recommended watching for those easily prone to motion sickness). To get the ping-pong ball-centric shots, the system uses a group of lenses and two small mirrors that pan, tilt and move so the camera itself doesn't have to. The mirrors rely on a speedy image tracking system that follows movement, rather than predicting it. Swapping the camera out for a projector also has some interesting applications -- it can paint digital pictures on whatever its tracking. Sounds like the perfect gadget for folks who wish their table tennis balls looked like emoji.
University of Tokyo turns real paper and ink into a display, could share doodles from a distance (video)
Forget e-paper: if the University of Tokyo's Naemura Lab has its way, we'll interact with the real thing. The division's new research has budding artists draw on photochromic paper with Frixion's heat-sensitive ink, turning the results into something a computer can manipulate. A laser 'erases' the ink to fix mistakes or add effects, and an ultraviolet projector overhead can copy any handiwork, fill in the gaps or print a new creation. The prototype is neither high resolution nor quick -- you won't be living out fantasies of a real-world A-Ha music video -- but the laser's accuracy (down to 0.0001 inches) has already led researchers to dream of paper-based, Google Docs-style collaboration where edits in one place affect a tangible document somewhere else. It's hard to see truly widespread adoption in an era where we're often trying to save trees instead of print to them, but there's an undeniable appeal to having a hard copy that isn't fixed in time.
University of Tokyo builds a soap bubble 3D screen, guarantees your display stays squeaky clean (video)
There are waterfall screens, but what if you'd like your display to be a little more... pristine? Researchers at the University of Tokyo have developed a display that hits soap bubbles with ultrasonic sound to change the surface. At a minimum, it can change how light glances off the soap film to produce the image. It gets truly creative when taking advantage of the soap's properties: a single screen is enough to alter the texture of a 2D image, and multiple screens in tandem can create what amounts to a slightly sticky hologram. As the soap is made out of sturdy colloids rather than the easily-burst mixture we all knew as kids, users won't have to worry about an overly touch-happy colleague popping a business presentation. There's a video preview of the technology after the jump; we're promised a closer look at the technology during the SIGGRAPH expo in August, but we don't yet know how many years it will take to find sudsy screens in the wild.
Japanese robot trolls humans at rock-paper-scissors, sadly wasn't named the UMADBRO 9000 (video)
Japan got itself in the good graces of many a Futurama fan after creating Bender's ancestor. Then again, another Japanese robotic creation -- one that specializes in rock, paper, scissors -- may actually have more in common with the morally questionable, beer-guzzling bot. That's because this sneaky little future overlord wins 100 percent of its matches by using an oh-so human trait known as cheating. See, the researchers at the University of Tokyo's 4chan, er, Ishikawa Oku Laboratory programmed the "Janken" robot to recognize its human opponent's hand shape and counter it within a millisecond. Adding to the troll factor is the fact that it was unwittingly named the "Human-Machine Cooperation System" because, well, it needs the cooperation of some poor human sap to work its magic. The achievement joins other man-versus-machine milestones, including losses by humans in chess and shogi. Of course, the question now is, what happens if you pit two "Janken" machines against each other?
Researchers create incredibly thin solar cells flexible enough to wrap around a human hair
You've probably heard that the sun is strong enough to power our planet many times over, but without a practical method of harnessing that energy, there's no way to take full advantage. An incredibly thin and light solar cell could go a long way to accomplishing that on a smaller scale, however, making the latest device from researchers from the University of Austria and the University of Tokyo a fairly significant discovery. Scientists were able to create an ultra-thin solar cell that measures just 1.9 micrometers thick -- roughly one-tenth the size of the next device. Not only is the sample slim -- composed of electrodes mounted on plastic foil, rather than glass -- it's also incredibly flexible, able to be wrapped around a single strand of human hair (which, believe it or not, is nearly 20 times thicker). The scalable cell could replace batteries in lighting, display and medical applications, and may be ready to be put to use in as few as five years. There's a bounty of physical measurement and efficiency data at the source link below, so grab those reading glasses and click on past the break.
Robot uses semantic search to get a Subway sandwich, do Jared's evil bidding (video)
Old PR2 can already fold towels, play pool and grab an ice cold beer -- really, the Willow Garage robot is just one task of short of mastering the day-to-day activities of your average college student. What's that? It can get a sandwich, too? Never mind. And this isn't just any "get me a sandwich" command -- the stout white 'bot uses semantic search to infer possible locations for sandwich, using knowledge of similar objects and environmental models. In the below video, you'll see PR2 make its way to a refrigerator, in search of sustenance, only to come up empty-clawed. Undaunted, it hops on an elevator and makes its way to a Subway sandwich shop. The joint project from the University of Tokyo and University of Munich was recently shown off at recent robotics conference. No word on when PR2 will be programmed to hold the onions.
Canon's 8-inch CMOS sensor can record SPACE at 60fps
For whatever reason, Canon seemed more concerned with showing off its engineering prowess than finding a use for the giant 8-inch CMOS sensor it created last year. Fortunately, the super-powerful snapper has found its way into the 105-centimeter Schmidt Telescope at the University of Tokyo's Kiso Observatory. The sensor's size makes it a perfect fit to record in low-light; capturing the wonders of the universe in 0.3 lux at 60 fps. The University will premiere footage from the experiment, possibly with nibbles, after September 19th -- presumably in a theater with a blanket ban on people muttering the introduction to Star Trek as it plays.
PIGORASS quadruped robot baby steps past AIBO's grave (video)
Does the Uncanny Valley extend to re-creations of our four-legged friends? We'll find out soon enough if Yasunori Yamada and his University of Tokyo engineering team manage to get their PIGORASS quadruped bot beyond its first unsteady hops, and into a full-on gallop. Developed as a means of analyzing animals' musculoskeletal system for use in biologically-inspired robots, the team's cyborg critter gets its locomotion on via a combo of CPU-controlled pressure sensors and potentiometers. It may move like a bunny (for now), but each limb's been designed to function independently in an attempt to simulate a simplified neural system. Given a bit more time and tweaking (not to mention a fine, faux fur coating), we're pretty sure this wee bitty beastie'll scamper its way into the homes of tomorrow. Check out the lil' fella in the video after the break.
New developments in atomic clock technology beat accuracy records, may inspire Ke$ha's next hit
According to a recent Penn State study that uses a new way to calculate time-telling precision, the CsF2 cesium-based atomic clock at the UK's National Physical Laboratory is almost twice as accurate as originally thought -- meaning it will only gain or lose one single second over the course of 138 million years. This atomic clock isn't the only competitor for best-in-show, as researchers at the University of Tokyo have also announced a new record, claiming their optical lattice atomic clock observes atoms a million times faster than a traditional atomic clock -- achieving accuracy up to 18 digits in a one second measurement. Although researchers say the technology would gain or lose a second significantly faster than the cesium-based variety (31.7 million years), it could change the way scientists perceive time and space, giving us new insights into fundamental constants of physics. "Until now, clocks have been thought of as tools for sharing common time. But with clocks like this, conversely, we can understand that time passes at different speeds, depending on the time and place a clock is at," said Hidetoshi Katori of the University of Tokyo. Of course, both atomic clocks can help us stay timely, but they also have practical applications for everything from deep-space networking, to predicting earthquakes and GPS navigation. With this type of accuracy, looks like none of us will be getting away with showing up late to work anymore. Check out a video about the optical lattice clock after the break.
Glucose sensor skin implant glows when blood sugar spikes
Checking blood glucose levels used to mean a finger prick and a test-strip, but researchers at the University of Tokyo are offering a different approach: a glowing skin implant. After being injected with the 1 mm wide filament, it monitors your blood sugar by glowing when your level changes. Based on existing glowing glucose sensor technology, this hydrogel fiber is considered more accurate and stable than its predecessors, plus it requires no oxygen to function. So far, it's worked in mice for up to 140 days. Note to future human patients: don't eat a candy bar before you go to bed unless you want your arm looking like a nightlight.
Wrist sensor turns the back of your hand into a meaty haptic interface (video)
We're all intimately familiar with the backs of our hands, so why not use them as a haptic interface to control our gadgets? That's the idea behind the device pictured above -- a nifty little wrist sensor that turns your paw into a flesh-toned trackpad. Designed by Kei Nakatsuma, a PhD student at the University of Tokyo, this contraption employs infrared sensors to track a user's finger as it moves across the back of a hand. These movements are mirrored on a wristwatch-like display, thanks to seven IR detectors and a set of piezoelectric sensors, effectively turning any digit into an organic stylus or mouse. Nakatsuma, who unveiled his work at this week's SIGGRAPH, says his creation can't handle the more complicated, pinching or rotating gestures you could manipulate on most smartphone touchscreens and acknowledges that the screen can be difficult to read in direct sunlight. But the underlying technology could pave the way for similarly handy designs, while allowing users to interact with their gadgets without having to constantly glance at their screens, or go fishing in their pockets. Feel your way past the break to see a video of the device in action.
Tokyo researchers hijack your hand, help you play the koto (video)
Researchers over in the land of the robot-obsessed have found a new, non-invasive way to control your hand while your brain recoils in horror. Reassuringly named the PossessedHand, this belt of electro-stimulation wraps its pad of twenty-eight electrodes around your forearm triggering a range of sixteen bewitched joint actions. Project leader Emi Tamaki claims it feels more like a light massage than say, a full-on Freejack. However, one test subject confessed, "[It was] like my body was hacked" -- so that's comforting. This joint production between the University of Tokyo's Rekimoto Lab and Sony Computer Science Laboratories was first tested as a musical training aide, but could someday help stroke victims regain mobility. For now, the stimulation isn't strong enough to turn you into an automated Steve Vai (or secret assassin), but it definitely lends new meaning to 'hands-off.' Check the video after the break for a demonstration and some unsettling narration.
First light wave quantum teleportation achieved, opens door to ultra fast data transmission
Mark this day, folks, because the brainiacs have finally made a breakthrough in quantum teleportation: a team of scientists from Australia and Japan have successfully transferred a complex set of quantum data in light form. You see, previously researchers had struggled with slow performance or loss of information, but with full transmission integrity achieved -- as in blocks of qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions -- we're now one huge step closer to secure, high-speed quantum communication. Needless to say, this will also be a big boost for the development of powerful quantum computing, and combine that with a more bedroom friendly version of the above teleporter, we'll eventually have ourselves the best LAN party ever.
World Bank report finds selling virtual goods in games more profitable than 'real' economy
A report commissioned by the World Bank's infoDev unit has cast fresh light on one of the more fascinating aspects of our brave new interconnected world: the virtual economy. The "third-party gaming services industry" -- where wealthy but impatient players have someone else grind away at online games for them in exchange for monetary reward -- is one of the focal points of the study, chiefly owing to it having generated revenues in the region of $3 billion in 2009 and now serving as the primary source of income for an estimated 100,000 young folks, primarily in countries like China and Vietnam. What's encouraging about these findings is that most of the revenue from such transactions ends up in the country where the virtual value is produced, which contrasts starkly with some of the more traditional international markets, such as that for coffee beans, where the study estimates only $5.5 billion of the $70 billion annual market value ever makes it back to the producing country. The research also takes an intriguing look at the emerging phenomenon of microwork, which consists of having unskilled workers doing the web's version of menial work -- checking images, transcribing bits of text, bumping up Facebook Likes (naughty!), etc. -- and could also lead to more employment opportunities for people in poorer nations.

Elpida and Sharp team up for ReRAM in 2013: 10,000x the speed of current NAND flash chips
Want to know where the next breakthrough in mobile technology will come from? Well, if Elpida and Sharp have their way, the answer will be the usual suspect of Japan, where they're working away on new memory chips said to be capable of four orders of magnitude faster performance than the ordinary NAND flash storage of today. Dubbed ReRAM, or Resistive Random Access Memory, this project targets a 2013 date for commercialization and counts the University of Tokyo and Japan's National Institute of Advanced Industrial Science and Technology among its development team. Details on how such blinding speeds will be reached aren't readily available, but the Nikkei reports power consumption will be down to "virtually zero" when the memory's not in use. So with ReRAM and HP's memristors both set for three years from now, can we schedule NAND's funeral for 2014 or what?
Rat controls vehicle with its brain, Pinky and The Brain apply for 'one last run'
So, let's paint the picture, shall we? There's a rat, a bundle of electrodes, more wiring than an electrician would know what to do with and some sort of wheeled apparatus. In the background stands a team of crazed Japanese scientists, intent on never sleeping again until said rat controls said vehicle entirely with his mind. Nah, it's not a re-run of a WB classic -- it's real life, and it's happening now in a dark, shadowy corner at the University of Tokyo. The RatCar is a newly developed rat-vehicle experiment that researchers hope will open new doors for those with mobility issues; we've seen brain-machine interfaces change the lives of the disabled before, but giving them the ability to control their wheelchair with their mind (for instance) would be taking things to an entirely new level. As of now, the team still has to figure out how to accurately determine how much movement is coming from the rat's feet and how much is coming from its mind, but there's no question that the research shows promise -- just don't let the humanoids learn of our findings, okay folks?
Implantable blood sugar sensor could eliminate daily finger pricks
Science has been figuring out ways to sidestep those dreaded finger pricks for years now, but it's not often that we hear of such a permanent solution as this. A crew of researchers from The University of Tokyo and BEANS Research Institute are in the process of developing a newfangled blood sugar sensor that "reacts to glucose and lights up inside the body." 'Course, injecting dyes into humans in order to receive interpretable signals ain't exactly new, but hydrogel is what makes this approach unique. As the story goes, this jelly-esque material can be implanted within the body, enabling blood sugar levels to be monitored and measured externally with no pain or irritation whatsoever. In theory, a monitoring system could trigger an alert as soon as the internal levels dipped or rose beyond a predetermined extreme, giving those with diabetes a maximum amount of time to get things back in balance. There's nary a mention of when this goo will be green-lit by the FDA, but there's definitely a video explaining everything just past the break.
