Digital 'Cloud' could form over London for the 2012 Olympics

by Donald Melanson posted Nov 12th 2009 at 2:45AM

No, we're not talking about "the cloud" where data goes to disappear and (hopefully) be retrieved again. We're talking about an actual (well, artificial) cloud that promises to be both a real structure and a massive digital display. That's the bright idea of a team of researchers from MIT, anyway, and it's now been shortlisted in a competition designed to find a new tourist attraction to be built in London for the 2012 Olympics. Dubbed simply "The Cloud," the structure would consist of two 400-foot tall mesh towers that are linked by a series of interconnected plastic bubbles, which would themselves house an observation deck inside and be used to display everything from Olympic scores and highlights to a "barometer of the city's interests and moods" outside (that latter bit comes courtesy of the group's partnership with Google). As if that wasn't enough, the whole thing also promises to be funded entirely by micro-payments from the public (which would also determine its final size), and be completely self-powered, with it relying on a combination of solar power and regenerative braking from the lifts in the towers.

Sixth Sense creator to release code, wearable gesture interface becomes a reality for all

by Darren Murph posted Nov 7th 2009 at 10:12AM

If we're being honest (and trust us, we're being honest), Pranav Mistry's Sixth Sense contraption has always baffled us. It's kind of like Sony's Rolly. It looks cool, it sounds rad, but we're fairly certain only 2.49 people actually know and fully comprehend how it works. That said, we're more than jazzed about the possibility of having wearable gesture interfaces gracing every human we come into contact with, and rather than attempting to make his invention "comply with some kind of corporate policy," he's purportedly aiming to release the source code into the wild in order to let "people make their own systems." Nice guy, huh? All told, the Sixth Sense can be built for around $350 (plus oodles of unpaid time off), and we're ~~pretty~~ certain that a few talented DIYers can get this thing whipped into shape far quicker than Mega Corp X. So, how's about a release date for that code?

MIT's Affective Intelligent Driving Agent is KITT and Clippy's lovechild (video)

by Vladislav Savov posted Oct 30th 2009 at 4:48AM

If we've said it once, we've said it a thousand times, stop trying to make robots into "friendly companions!" MIT must have some hubris stuck in its ears, as its labs are back at it with what looks like Clippy gone 3D, with an extra dash of Knight Rider-inspired personality. What we're talking about here is a dashboard-mounted AI system that collects environmental data, such as local events, traffic and gas stations, and combines it with a careful analysis of your driving habits and style to make helpful suggestions and note points of interest. By careful analysis we mean it snoops on your every move, and by helpful suggestions we mean it probably nags you to death (its own death). Then again, the thing's been designed to communicate with those big Audi eyes, making even our hardened hearts warm just a little. Video after the break.

Pixel Qi e-ink / LCD hybrid display to debut on tablet next month?

by Darren Murph posted Oct 17th 2009 at 3:11PM

It's been far, far too long (read: four months) since we've heard a peep from the gentle souls over at Pixel Qi, but it looks like the long, heart-wrenching wait for the hybrid display that's bound to revolutionize Western civilization is nearing an end. According to the startup's CEO herself, Mary Lou Jepsen, the primetime-ready 3Qi display should make its glorious debut on an undisclosed tablet to be announced next month. For those out of the loop, this transflective display contains both e-ink and LCD properties, one for outdoor reading scenarios and the other for multimedia viewing. The amazing part is that toggling between the two is as simple as flipping a switch, which obviously means great things for battery life on whatever device it's shoved into. We'll be keeping our eyes peeled for more, but do us a favor and cross your fingers for good luck. Toes too, por favor.

Roof tiles change color based on the temperature, your house's mood

by Tim Stevens posted Oct 9th 2009 at 9:17AM

Okay, sure, ideally your entire roof would be comprised of solar tiles that would meet your entire house's energy demands and would also water your lawn and clean your gutters while they were up there. But, despite pledges of "affordability" something tells us it'll be awhile before your roof starts juicing your gadgets. This solution from MIT looks a little more practical -- and affordable. They're simply tiles that change color based on the temperature, Hypercolor style. In the cold they turn jet black, absorbing the sun's warmth and channeling that into the house. In heat they turn white, reflecting that same light and cutting down on cooling bills. Simple and smart. The MIT team calls the tech Thermeleon, and while early prototypes do change color as designed, it remains to be seen how durable the tech will be, and a leaky roof is no good regardless of how efficient. Asphalt shingles reign supreme for yet another year.

Video: OLED technology explained using a pickle and an Igor

by Vladislav Savov posted Oct 2nd 2009 at 9:53AM

Say bub, do you care to know what all that OLED jazz is about? We'll bet you do, but you don't wanna read some dry polysyllabic academic paper written by five guys during their time away from the lab. What you want is a sharp demonstration, preferably by an MIT professor, that goes straight to the point of what an Organic Light Emitting Diode is. Igor, roll in the pickle, please. Okay, he's not an Igor, his name is Vladimir Bulovic, but he does a terrific job of explaining how the passing of electric current excites organic molecules into creating those luscious ultra-bright colors we lust after that can fit inside ridiculously small spaces. Slide past the break to see the vid in full, and yes, it's just as weird as you think it'll be.

MIT students develop new 6dot braille labelmaker prototype

by Laura June posted Sep 26th 2009 at 4:37AM

A group of students at MIT have just unveiled a new prototype of a braille labelmaker / printer, the 6dot. Though not the first, the MIT group's model is apparently more advanced, easier to use, and cheaper than currently available models. Designed with the blind and visually impaired in mind, the labelmaker features an around the neck strap, and six buttons (for each of the dots of a braille character), allowing quick production of accurate labels, including contractions. The internal processor of the device can store up to 16 characters, and "prints" the characters onto adhesive label paper, which the user can then affix for easy identification of household items, such as medications, canned goods, and so on. Though it's still in prototype phase, it's possible the device could cost as little as $200 when it does hit the market.

MIT researchers tout progress with retinal implant - yes, it comes with a visor

by Donald Melanson posted Sep 24th 2009 at 1:57PM

As impressive as that tooth-eye implant was, we're guessing most folks had something more like this in mind when they considered the future of sight restoration. While it's still a bit early in development, and has yet to actually be implanted in anyone, this new retinal implant certainly seems to have the researchers at MIT excited, who say that tests with blind patients could begin within the next three years. The basic idea behind it was apparently inspired by the cochlear implants that have proven successful in restoring people's hearing, although in this case the implant works by electrically stimulating damaged nerve cells that would ordinarily send visual signals from the retina to the brain. According to the researchers, however, the system would only work on folks that have lost their sight due due retinitis pigmentosa or age-related macular degeneration, and it wouldn't restore complete sight, but could let them see enough to find their way through a room or walk down a sidewalk (which is certainly no small feat). They'll also have to wear a special set of glasses (or visor, if you prefer), which will not only wirelessly send images to the implant, but keep it powered wirelessly through a set of coils.

Carbon nanotubes find yet another purpose, could star in ultra-reliable batteries

by Darren Murph posted Sep 21st 2009 at 8:29PM

Carbon nanotubes are kind of like peanuts. They both seem pretty simple at first glance, but with a little work, you can make pretty much anything out of 'em. Take this case, for example, as MIT boffins have discovered that by forming the tube-shaped molecules of pure carbon into minuscule springs, they could be "capable of storing as much energy, pound for pound, as lithium-ion batteries." The real kicker is exactly how they'd do it -- "more durably and reliably." Essentially, these newfangled cells could be left alone for years on end without losing their charge, and unlike conventional batteries, these wouldn't suffer from performance degradation when exposed to temperature extremes. Of course, anything as pie-in-the-sky as this is probably at least a decade or so out from Walmart shelves, but considering that the group responsible has already filed a patent, we'd say they're pretty confident in the possibilities.

Video: MIT robofish set to snoop the deep seas

by Vladislav Savov posted Sep 2nd 2009 at 6:39AM

MIT has been at this robotic fish lark for a long, long time, and its latest iteration is a true testament to all the effort and energy put in. The first prototype, 1994's Robotuna, was four feet long and had 2,843 parts driven by six motors, whereas the new robofish is no longer than a foot, carries one motor and has exactly ten components, including the flexible polymer body. The hardy and relatively inexpensive drones can be used as substitutes for AUVs in tight spaces, inhospitable environments and the like, but their earliest adopters are likely to be supervillains in need of surveillance bots for their moats.

ROS: a common OS to streamline robotic engineering

by Vladislav Savov posted Aug 13th 2009 at 1:01AM

The biannual International Joint Conference on Artificial Intelligence has this year shed light on a new effort to standardize robot instructions around a common platform, so that designers won't have to "reinvent the wheel over and over" with every project. Presently, robot design is undertaken in an ad hoc fashion, with both hardware and software being built from scratch, but teams at Stanford, MIT and the Technical University of Munich are hoping to change that with the Robot Operating System, or ROS. This new OS would have to compete with Microsoft's robotics offering, but the general enthusiasm for it at the conference suggests a bright future, with some brave souls even envisioning a robot app store somewhere down the line.

Glass leaves sweat to generate electricity, get nervous in public situations

by Laura June posted Aug 3rd 2009 at 4:13AM

Researchers at the University of California, Berkeley, the University of Michigan and MIT have created glass "leaves" with networks of veiny channels filled with water. The smallest channels extend all the way to the edges of the leaf, where open ends allow water to evaporate, which draws water along the central stem of the leaf -- at a rate of about 1.5 centimeters per second. The glass leaves have been wired for electricity by adding metal plates to the walls of the central stems and connecting them to a circuit. Researchers then charge the plates and the water inside the stems creates two conducting layers separated by an insulating layer, which acts as a capacitor. The waterflow is then periodically interrupted with air bubbles, and every time a bubble passes through the plates a small electrical current is generated -- about 2 - 5 microvolts per bubble. The team thinks that on a large scale, artificial trees could be use to generate large amounts of energy entirely through evaporation.

MIT's Bokode tech calls out zebra stripes, QR codes for battle of barcode supremacy

by Tim Stevens posted Jul 28th 2009 at 9:24AM

Since barcodes are the sign of the devil (must be true, we read it on the interwebs) it's no surprise that everyone wants to replace 'em. QR codes have been quite popular, allowing people and companies to tag their stuff with colorful decals filled with bits and bytes, and of course RFID tags are still going strong, but a team of researchers at MIT has come up with something better: Bokode. It's effectively a tiny little retroreflective holograph that is just 3mm wide but, when a camera focused to infinity sweeps across it, the Bokodes become clear and appear much larger, captured in the video below. In this way they can contain "thousands of bits" of data and, interestingly, show positional information too, meaning the camera knows where in 3D space it is in relation to the tag. This, of course, has hundreds of potential applications ranging from grocery shopping to augmented reality, and should lead to new and exciting ways for scholars to interpret/misinterpret Revelations.

DIY wearable computer: now you don't have to go to MIT to look like a total nerd in public

by Paul Miller posted Jul 25th 2009 at 7:55PM

We admit it: despite our general disregard for the benefits of higher education, we've always harbored deep jealousy for those incredibly intelligent jerks at MIT's Media Lab, traipsing around Massachusetts in their incredibly great wearable computers. Well, now that a MicroPCTalk forum member has built his very own wearable computer from a few spare parts lying around the house, we can finally put aside those futile dreams and get to work on our very own nerd-badge-of-honor. Mr. Fiveseven808 took a VAIO UX, Myvu Crystal wearable display, a bevy of Bluetooth peripherals and a iDEN i425 handset for connectivity. Sadly, his UX has since died, but there's more UMPC where that can, and those elitist MIT types can't keep us down forever.

Video: MIT working on rapid recharging for electric vehicles

by Vladislav Savov posted Jul 23rd 2009 at 7:43AM

MIT's electric vehicle prototype may be a long way off from being completed, but if we let that stop us from discussing EVs, we might never talk about them. The headline ambition of the elEVen project is a full recharge within 10 minutes, which would eliminate somewhere between four and ten hours of waiting. Speedwise, the Electric Vehicle Team is aiming for a 100 mph top speed from a 250-horsepower / 187 kilowatt AC induction motor, and a not unheard of 200-mile cruising range. To achieve their rapid juicing aim, the students will strap 7,905 lithium iron-phosphate cell batteries from A123Systems to a gutted 2010 Mercury Milan Hybrid body. The batteries' low internal resistance is what makes things possible, but further hurdles, such as finding a sufficiently powerful energy source, would have to be overcome before any sort of widespread use may occur.
