Transparent gel speaker plays music through the magic of ionic conduction video

It may be hard to believe, but that transparent disk in the photo above is actually a fully functioning speaker. A team of researchers at Harvard’s School of Engineering and Applied Sciences have pioneered a never before seen application of ionic conductivity by creating a see-through artificial muscle that can produce sounds spanning the entire audible spectrum. While ionic conduction isn’t a novel idea, it’s been considered impractical due to the fact that ionic materials react poorly to high voltage. The team, which included postdoctoral research fellows Jeong-Yun Sun and Christoph Keplinger (pictured above), circumvented that obstacle by placing a layer of rubber between two sheets of transparent conductive gel, allowing the system to work with both high voltage and high actuation, two qualities necessary for sound reproduction. Theoretically, soft machine technology such as this can be used to do much more than play Grieg’s Peer Gynt, particularly in the fields of robotics, mobile computing and adaptive optics. To watch it in action, check out the video after the break.

Robot’s Face Determines Level Of User Comfort

Robot’s Face Determines Level Of User ComfortHow does a robot know that a human is not feeling comfortable at all? I suppose an entire bunch of sensors as well as the right algorithms will be able to do the job, but there is a recent University of Auckland study that showed how a preference for humanlike features on a robot’s display screen might change the way robots work in the future. Around 60% of the participants prefered a robot that displayed the most humanlike skin-colored 3D virtual face, compared to a robot that lacks a face, while a robot that has silver-colored simplified human features on its “face” stand at a 10% approval rate. I guess this means that future robots that are being developed for healthcare as well as home care ought to feature a face that is as close to that of a human as possible in order to build a “bridge” of sorts between human-robot interaction.

Dr Elizabeth Broadbent from the University’s Department of Psychological Medicine, shared, “It’s important for robot designers to know how to make robots that interact effectively with humans, so that people feel comfortable interacting with the robots. One key dimension is robot appearance and how humanlike the robot should be.” Would you mind if future robots were like Sonny in I, Robot?

    IDC Lowers 2013 Tablet Forecast To 227M, As Phablets And Wearables Crowd Into The Market

    kids on tablets

    The PC industry may be shaken up by the rapid encroachment of tablets into consumer and enterprise spending habits — a trend that’s seeing lighter devices like the iPad, as well as cheaper tablets like Amazon’s Kindle Fire and more, eat into the market share of bigger and more expensive computers. But it’s all a matter of perspective: today IDC said that it’s actually lowering forecasts for tablet shipments this year and in the future.

    “Growing competition”, IDC says, from smartphones with bigger screens (the recently-legitimized phablet) and wearables like smart watches, combined with a lack of exciting tablet product launches in Q2, are leading the analysts to says that there will be 227.4 million tablets shipped worldwide in 2013, down some 2 million from 229.3 million as previously estimated.

    Yes, it’s not a huge drop, and you can argue that these are only estimates anyway. And it’s still some 57.7% higher than 2012 shipments. But IDC’s figures point to some themes that are worth watching for: whether even less-expensive tablets are possibly still too expensive for what consumers are willing to pay; whether even tablets — in some regards pared-down in functionality from PCs — are still too over specced for what many consumers want and need; and the issue of how much of our wallet we will want to dedicate to these products, as more of them enter the market.

    On the enterprise side, IDC notes that right now, in fact, the tablet is pretty minor but is growing: It notes that tablet adoption in sectors like education and retail collectively accounted for 10% of all tablet sales in 2012, and that will only grow to 20% by 2017.

    IDC also notes that it’s starting to see more developed markets already take their feet off the gas in terms of rapid adoption, with “maturing markets such as the U.S. now expected to cede share more rapidly to emerging markets such as Asia/Pacific.” It predicts that by 2017 there will be 407 million tablets shipped.

    More immediately, competitive pressures will mean lower prices for tablets coming soon, IDC notes. “We expect average selling prices to continue to compress as more mainstream vendors utilize low-cost components to better compete with the whitebox tablet vendors that continue to enjoy widespread traction in the market despite typically offering lower-quality products and poorer customer experiences,” writes Tom Mainelli, research director for tablets.

    In terms of regional activity, IDC points out that North America, Western Europe and Japan, which had traditionally been the leaders in tablet adoption, are already seeing some slow-down in sales, compared to other parts of the world. Today they account for 60.8% of the market, but that will drop to 49% by 2017, with emerging markets making up the remaining 51%. (Another proof point for why it’s so important for companies like Google, Facebook and others to build out their businesses in these markets.)

    “Year-on-year growth is beginning to slow as the tablet market approaches early stages of maturity,” said Jitesh Ubrani, research analyst for IDC’s Worldwide Quarterly Tablet Tracker. “Much of the long-term growth will be driven by countries like China where projected growth rates will be consistently higher than the worldwide average.”

    Tiny human 'brains' grown in lab

    Mouse brains were the first to be grown, but when it comes to discovering the inner workings of the human brain, as Juergen Knoblich of the Institute of Molecular Biology (IMB) in Austria put it: “mouse models don’t cut it.” The institute has managed to grow some adorable-sounding tiny human brain models that include parts of the cortex, hippocampus and retinas through stem cells. The lab-grown tissue will allow researchers to peer into the early stages of human brain development in far higher detail than ever before. Growing the little gray matter samples involved adult cells reprogrammed to behave like embryonic stem cells and giving them a cocktail of vital brain development nutrients.

    In under a month, they had grown to between 3 and 4mm across, with several structures that are found in the fully-formed versions. Through imaging techniques, the scientists were even able to pick up neural activity — we’ve added the video after the break. The models are already providing insights and new ideas on brain development. According to the New Scientist, if the researchers were able to adjust their techniques to include stem cells that develop into blood vessels, future models could offer more detailed knowledge on conditions like schizophrenia and autism.

    Researchers Build The First Brain-To-Brain Control Interface

    B2B-image-300x161

    Researchers at the University of Washington, Rajesh Rao and Andrea Stocco, have created a remote, non-invasive brain-to-brain interface that allowed Rao to move Stocco’s finger remotely on a keyboard using his thoughts.

    “The Internet was a way to connect computers, and now it can be a way to connect brains,” Stocco said in a release. “We want to take the knowledge of a brain and transmit it directly from brain to brain.”

    Rao has been working on these interfaces for a decade and brain-to-brain control has been achieved in mice using invasive techniques. This is the first time the process has been used on humans and requires a transcranial magnetic stimulation coil to be placed on the head of the subject. The user in control can then send a signal by reacting to something on a screen or in the room. A electroencephalography machine picks up the brain waves and transmits them to the subject who, in turn, mimics the motion of the controller.

    Thus far the team has been able to demonstrate how to play a simple video game remotely. The controller plays in the game in one room in the lab and the sensors pick up his hand motions. The signal to initiate these motions is sent to the subject and, in turn, the subject begins mimicking the actions of the controller using the same game interface, essentially playing the game remotely without seeing the screen.

    This is not mind control. The subject cannot be controlled against his or her will and neither party can “read” each other’s thoughts. Think of this as sending a small shock controlled via the Internet to trigger a fairly involuntary motion.

    The researchers are planning to expand this to more complex motions and try it on other subjects in the next round of testing.

    Human brain-to-brain interfacing seems like the stuff of fiction (Pacific Rim, anyone?), but researchers at the University of Washington have made it a reality. A team led by faculty members Rajesh Rao and Andrea Stocco claim to have pioneered the world’s first human-to-human experiment of the sort. Rao and Stocco were placed in different buildings and hooked up to two devices to record, interpret and send their brain signals via the internet. The sender (Rao) wore an EEG machine while the receiver (Stocco) was connected to a transcranial magnetic stimulation coil. The experiment was performed with a simple arcade-style video game, the objective of which was to shoot baddies out of the sky. Rao watched the screen and visualized lifting his hand to press the space bar to fire, but Stocco was the trigger man. Clear across campus, Stocco’s finger tapped the space bar at the appropriate time, eliminating the target, despite being unable to hear or see the game’s display.

    A Hyper-Realistic Archery Sim Is the Safest Hunger Games Proxy

    You don’t see a lot of first person shooter games that opt for a bow and arrow in lieu of a machine gun, but that’s probably because no one has created a bow interface as authentic as what Masasuke Yasumoto at the Tokyo University of Technology has developed.
