I HAVE TO SAY, AS A RABID GOOGLE FANBOY,…

I have to say, as a rabid Google fanboy, that I was rather disappointed with the Glass demo today at #io12 . First of all, we only saw pictures. Sorry, but in the age of ubiquitous smart phones, I’m not all that impressed when a small device can take a picture. Hands-free doesn’t quite wow me as much as they think it should. Hands free is certainly not worth $1500. Second, am I supposed to believe that it will ever be possible to have a flawless high-bandwidth Wifi connection from a mile in the air? Whatever tech they were using to pull it off, it’s tech that I’ll never have access to as a consumer, and that completely took the wind out of my sails. I don’t want to see how billionaires at play will use the hardware, I want to know how it will change my life. If you want to impress me, +Project Glass, you need to show me the interface and the overlay. This is an augmented reality device, yet apparently your pitch involves demonstrating just how little it will actually augment your reality. “Glass- the tech so advanced it doesn’t do anything at all!” Sorry, +Google, but I want your products to make me into a cyborg. Getting the tech out of the way defeats that purpose. The pictures-and-nothing-else demo for Glass wasn’t just counter-intuitive, it runs contrary to the very nature of the device they’ve designed. This makes me worries that Glass is so far ahead of its time that Google doesn’t actually know what it’s doing. My big worry is that if Google fails with this device, it will set the augmented reality movement back a decade by scaring off investors in similar tech. That would make me very sad. This is tech that […]

I’M CURRENTLY WORKING IN THE SAME BUILDING…

I’m currently working in the same building as some of the most brilliant mathematicians of our generation. Earlier today, John Nash walked by my classroom and poked his head in the window. I tried really hard not to squeal. Fine Hall changed location in the 60’s, so unfortunately this isn’t the same building that Church, Turing, Godel, and mathematicians at Princeton in the early 20th century used. Still, the Institute for Advanced Study is right down the road, just a few blocks from Einstein’s old home.

WHAT HONEYBEES CAN TEACH US ABOUT GANG-RELATED…

What Honeybees Can Teach Us About Gang-Related Crime “All people are like this,” Brantingham says. “You have focal points around your house, or your community center. Honeybees have their hive. Hyenas have their den. And lion prides have their den. Organisms all tend to have an anchor point for their activities, and gangs are no different.” “A mathematical equation obviously can’t take into account the level of detail sociologists can collect on the ground, interviewing gang and community members, documenting graffiti and crime locations. But this theoretical model turned out to predict with pretty remarkable accuracy actual gang violence in Los Angeles. This model suggests most violence would occur not deep into gang territory, but on the contentious borders between gangs. The researchers overlaid actual crime data on top of their model – covering 563 violent crimes, between 1999 and 2002, involving these 13 gangs – and that’s exactly what they saw. “Violent crime in this part of Los Angeles clustered along the theoretical boundaries between gangs produced by the same math equation that tells us how rival honeybees divvy up space. As a practical matter, this suggests police officers might want to focus their resources on these seams between gang territories.” More: http://www.theatlanticcities.com/neighborhoods/2012/06/what-honeybees-can-teach-us-about-gang-related-crime/2377/ via +David Basanta

RESHARED POST FROM JOHN VERDON

“To be sure, Wikipedia’s Boko Haram entry is clearer. But the BBN system captures everything that appears on news sites—not just on topics people chose to write Wikipedia pages about—and constantly and automatically adds information, says Sean Colbath, a senior scientist at BBN Technologies who helped develop the technology. “I could go and read 200 articles to learn about Bashar Al-Assad (the Syrian dictator). But I’d like to have a machine tell me about it,” says Colbath. (The system, by the way, picks up the fact that the brutal Al-Assad is also a licensed ophthalmologist.) “It starts by detecting an “entity”—a name or an organization, such as Boko Haram, accounting for a variety of spellings. Then it identifies other entities (events and people) that are connected to it, along with statements made by and about the subject. “It’s automatically extracting relationships between entities,” Colbath says. “Here the machine has learned, by being given examples, how to put these relationships together and fill in those slots for you.” John Verdon originally shared this post: An Online Encyclopedia that Writes Itself – Technology Review Machine reading effort builds dossiers on people and organizations from translated news sources.

RESHARED POST FROM KYLE CRIDER

“About 2.5 million years ago, humans first used tools to make other tools then to make tools assembled from different parts to make a unit with particular qualities, such as wooden spears with stone spearheads (ca. 200,000-300,000 years ago.) The bow and arrow and other complementary tool sets made it possible for prehistoric humans to greatly increase the flexibility of their reactions. “There are many basic complementary tool sets: needle and thread, fishing rod and line, hammer and chisel. The bow and arrow are a particularly complex example. The reconstruction of the technique shows that no less than ten different tools are needed to manufacture a simple bow and arrows with foreshafts. It takes 22 raw materials and three semi-finished goods (binding materials, multi-component glue) and five production phases to make a bow, and further steps to make the arrows to go with it. The study was able to show a high level of complexity in the use of tools at an early stage in the history of homo sapiens.” Full article: http://journals.cambridge.org/action/displayJournal?jid=CAJ From the abstract: “We show that, when isolated, neither the production of a simple bow, nor that of a stone-tipped arrow, can be reasonably interpreted to indicate tool behaviour that is cognitively more complex than the composite artefacts produced by Neanderthals or archaic modern Homo. On the other hand, as soon as a bow-and-arrow set is used as an effective group of tools, a novel cognitive development is expressed in technological symbiosis, i.e. the ability to conceptualize a set of separate, yet inter-dependent tools. Such complementary tool sets are able to unleash new properties of a tool, inconceivable without the active, simultaneous manipulation of another tool. Consequently, flexibility regarding decision-making and taking action is amplified.” +Adam See Kyle Crider originally shared this post: Complex thinking behind the […]

HUMAN NATURE AND TECHNOLOGY CENTER FOR TALENTED…

Human Nature and Technology Center for Talented Youth Princeton, NJ Today starts a three week intensive summer course I’ll be teaching for the Center for Talented Youth at the Princeton site. I’ll be teaching in Fine Hall, home of the Princeton mathematics department. I’m very excited! The course will be taught to 15 gifted high school students, and it will be intense: seven hours a day, five days a week, for the next three weeks straight. This gives us the time to give a comprehensive treatment of the philosophy of technology, starting with Plato and Aristotle and working our way through figures as diverse as Marx, Heidegger, and Turing before reaching contemporary thinkers like Shirky, Latour, and Sterling. The students will be busy the whole time with reading and writing assignments, debates and research projects, and a whole host of other activities. Its a whirlwind ride; I’ve been teaching the course for the last seven years, and it gets better every year. Although the student’s won’t be on line directly, the class will have some online presence. You can see the tentative syllabus here: https://docs.google.com/document/d/1RyJF_a3bdsRD5myaso9Eo47r9byaT_xpz_RHdAhswFI/edit You can follow us on Twitter @htecb: https://twitter.com/#!/htecb Our first research project, starting tomorrow afternoon, will be a collaborative Prezi on the top technology stories from the last year.

“Working for Internet” is about the most compressed statement for the #attentioneconomy that I can think of. Hint: check my profile. The recent story of the bus lady who raised half a million dollars after her harassment video on YouTube is in some sense another success story of Internet employment, though getting yelled at by kids isn’t exactly a reliable vocation. +Matt Uebel recently posted an article discussing Planetary Resource’s launch of a Kickstarter campaign to fund their multibillion dollar asteroid mining mission.

RESHARED POST FROM DEEN ABIOLA

In my recent #attentioneconomy primer, I included a long selection from +Bruce Sterling‘s novel The Caraytids, which describes a community called the Acquis that organizes entirely by monitoring attention through the use of an immersive augmented reality headset called the “sensorweb”. The whole novel is wonderful, but the discussion of attention camps is particularly insightful. Despite the excitement about these glasses I’ve seen and heard very little to suggest that people understand how they will ultimately be used. To that end, I’m quoting an extended but important passage below. ________ When they had docked at Mljet in their slow-boat refugee barges, they’d been given their spex and their ID tags. As proper high-tech pioneers, they soon found themselves humbly chopping the weeds in the bold Adriatic sun. The women did this because of the architecture of participation. They worked like furies. As the camp women scoured the hills, their spex on their kerchiefed heads, their tools in their newly blistered hands, the spex recorded whatever they saw, and exactly how they went about their work. Their labor was direct and simple: basically, they were gardening. Middle-aged women had always tended to excel at gardening. The sensorweb identified and labeled every plant the women saw through their spex. So, day by day, and weed by weed, these women were learning botany. The system coaxed them, flashing imagery on the insides of their spex. Anyone who wore camp spex and paid close attention would become an expert. The world before their eyeballs brimmed over with helpful tags and hot spots and footnotes. As the women labored, glory mounted over their heads. The camp users who learned fastest and worked hardest achieved the most glory. “Glory” was the primary Acquis virtue. Glory never seemed like a compelling reason to work hard-not when you […]

BALLOON PLUS COFFEE GROUNDS EQUALS VERSATILE ROBOT GRIPPER

Picking up things is pretty sucky for robots, since so many complex variables are involved. And the more complicated the object, the more complicated the task of picking it up seems to be. This new type of robotic gripper can pick up all sorts of objects (the more complicated, the better) by using a technique called ‘jamming.’ Jamming is simple and effective: a balloon is filled with coffee grounds. When air is blown into the balloon, it expands slightly, the coffee grounds can move around a little bit, and the gripper can conform to complex objects. When air is sucked out of the balloon, the coffee grounds bind together, and the object is now firmly held. It’s basically a practical method of shape shifting. Cool! The funny thing about jamming is that effectiveness of the grip is, in most cases, directly proportional to the complexity of the object. This means that flat, smooth objects like sheets of paper are pretty much impossible to pick up using jamming, which is the inverse of using a different technique like suction. Porous or squishable objects like cotton balls also don’t lend themselves to being gripped in this manner. But this is a small price to pay for being able to pick up more or less any object without having to first examine that object and calculate exactly how to go about doing it… Plus, a balloon and coffee grounds? Sounds pretty damn cheap to me. [ PNAS ] VIA [ Hizook ]

LOCKHEED MARTIN SMSS

Lockheed Martin’s original pack-hauling robot was named (appropriately enough) MULE, which stood Multifunction Utility/Logistics and Equipment… Vehicle. MULE got canceled at the beginning of this year, though, and its effective replacement seems to be the SMSS, or Squad Mission Support System. SMSS is completely autonomous, and will either follow behind a soldier or follow preset GPS waypoints, all while avoiding obstacles with its conspicuous and fragile looking LIDAR system. It can 1200 pounds of gear, has a range of over 200 miles, and also functions as a mobile gear charger. The long-term vision of this system can accommodate armed variants, while improving its reconnaissance, surveillance and target acquisition capabilities within the concept of supervised autonomy. A squad-size manned or unmanned support vehicle is critical to today’s asymmetrical and urban battlefields. It sounds like Lockheed Martin’s long-term vision is basically to turn SMSS into what MULE was supposed to be: a six wheeled platform that, in addition to hauling equipment, could (by simply adding some modular accessories) also be used for this sort of thing: Of course, MULE was undoubtedly going to be super expensive and much harder to develop, but it had the potential to offer tons of flexibility, which personally I think is the key to the future of the military in general. Oh, and that thingy it used to get past the barbed wire? It looks an awful lot like one of these. Anyway, I guess it’s good to see that Lockheed Martin’s original concept isn’t totally dead, it’s just kinda sad when an awesome robot gets made so much less awesome, even if it is substantially more practical.

MICROMOUSE SOLVES MAZE IN 5 SECONDS FLAT

It’s been a little while since we’ve posted a micromouse vid, so here’s a good one. It’s from a competition in Chubu, and the winner completes its final run in 5 seconds. Or maybe 4. Skip to 4:30 if you’re interested in the speed but not the exploration phase. I can only assume that micromice are approaching some kind of asymptotic maximum speed when it comes to maze solving, but I’m optimistic that people will still keep on inventing ways of making them faster and more efficient… Vacuum power was one, and I’m sure there are more. It’s an interesting problem, though, because there has to be a compromise between speed and stability, which may involve slowing down, as this high speed video shows: That robot is Tetra, who we’re already somewhat familiar with, but in this competition it took second place to the winner in the first vid, a micromouse called EggTorte.

ROBOTS CLIMB LIKE PEOPLE

I have to say, this is simultaneously one of the most and least conventional climbing robots I’ve ever seen. We’re used to all kinds of weird stuff like claws and geckos and electroadhesion, but these robots just climb up with boring arms and legs and hands and feet. Which is actually kinda interesting. Apparently these guys (called Yume Robo) aren’t exactly new… They’ve been climbing up and down a 15 meter high wall, every 20 minutes, for the last 184 days, until just last week. They’re dressed in silver work suits, but I don’t claim to know what they heck those antennae are for. One more vid, after the jump. VIA [ CrunchGear ]

Cody here comes from Georgia Tech’s Healthcare Robotics Lab; we first met him back in March. Since then, Cody’s been busy, learning how to give sponge baths. All an operator has to do is to select an area of a patient, and Cody will autonomously go to work.

MINSKY TENTACLE ARM WAS GROPINGWOMEN IN 1968

Marvin Minsky helped found what is now known as the MIT Computer Science and Artificial Intelligence Laboratory back in 1959. Only 9 years later, he constructed this tentacle arm, which shows an impressive level of sophistication. There isn’t too much info about it, but here’s the caption from the video, which was posted by MIT CSAIL: “This film from 1968 shows Marvin Minsky’s tentacle arm, developed at the MIT AI Lab (one of CSAIL’s forerunner labs). The arm had twelve joints and could be controlled by a PDP-6 computer or via a joystick. This video demonstrates that the arm was strong enough to lift a person, yet gentle enough to embrace a child.” [ MIT CSAIL ]

ARTIFICIAL INTELLIGENCES COMPETE WITH EACH OTHER, HUMANS AT STARCRAFT

Artificial intelligence systems are good at tackling problems that can be solved using brute force, like chess… All the computer has to do is calculate out every possible permutation of moves and pick the best one. They’re also pretty good at games like poker, where even with incomplete information, a computer can make a move that is statistically ‘best.’ And lastly, they’re good at making decisions far more quickly than a human. When you combine all of these separate characteristics into one game, things get exponentially more complex, but also much more like real life. And this is why people are trying to teach computers how to play StarCraft, at a level where they can compete with even the best human players. UC Santa Cruz hosted the 2010 StarCraft AI Competition, which put AI programs through a series of different StarCraft testing scenarios to determine the most effective AI system at micromanagement, small scale combat, tech limited games, and of course full gameplay. The video above shows a bunch of highlights; especially notable is the absolutely brutal use of mutalisks by the eventual AI winner, UC Berkeley’s Overmind. The last clip in the highlight video shows an AI taking on a world class human player, who wins handily. It’s only a matter of two or three years before humans have no chance against programs like these, however… And the reason (I think) is quite straightforward: the computer can micromanage every single unit it owns, on every part of the map, at the same time. A human can’t. Once the AI reaches a competent level of strategy and unit use (it’s not there yet), we’re screwed, because the AI can just launch multiple simultaneous micromanaged attacks. There are lots more videos of the different AI programs competing against each other on […]
