Hasta La Gadget!

The bad news: just as much of the world is starting to get excited about the prospects of 3D printing, science is moving on to the world of 4D. The good news: in the future, you might not have to assemble that Ikea chair yourself. “4D printing” is the term cientists are using to refer to a technology that MIT’s Skylar Tibbits talked up during a recent TED appearance. The fourth “d” here is time, referring to an object that, once printed, is capable of changing shape (over time, naturally).

“Essentially the printing is nothing new,” Tibbits told the BBC. “It is about what happens after.” So far the concept has been demonstrated with thin strands of plastic, which, once added to water, form into a predetermined shape, using energy from the absorption. Suggested future applications involve furniture, pipes, bikes and buildings. First, however, scientists will have to demonstrate the technology on a larger structure, of course, and they’ll explore the possibility of other energy sources, like heat, sound and vibration.

Know that feeling when someone wanders too far into your personal space? The University of Illinois‘ Victor Mateevitsi does, which is why he’d built a suit that does the job to a far greater degree of accuracy. SpiderSense is a onesie that uses a series of microphones to rend and receive ultrasonic signals from the space around you, like high frequency radar. When the outfit senses something approaching, a robotic arm corresponding to the microphone exerts pressure on your skin, pointing you in the direction of the danger. Mateevitsi tested the gear by blindfolding researchers and asking them to throw a cardboard ninja star whenever (and wherever) they sensed a threat — with positive results 95 percent of the time. SpiderSense will get its first public showing at Stuttgart’s Augmented Human conference in March and it’s hoped that the hardware will eventually help Blind people get around easier.

Science! A team of bioengineers and physicians over at Cornell University recently detailed their work to 3D print lifelike ears that may be used to treat birth defects like microtia and assist those who have lost or damaged an ear due to an accident or cancer. The product, which is, “practically identical to the human ear,” according to the school, was created using 3D printing and gels made from living cells — collagen was gathered from rat tails and cartilage cells were taken from cow’s ears. The whole process is quite quick, according to associate professor Lawrence Bonassar, who co-authored the report on the matter,

“It takes half a day to design the mold, a day or so to print it, 30 minutes to inject the gel, and we can remove the ear 15 minutes later. We trim the ear and then let it culture for several days in nourishing cell culture media before it is implanted.”

The team is looking to implant the first ear in around three years, if all goes well.

Mobile image processing in itself isn’t special when even high dynamic range shooting is virtually instant, at least with NVIDIA’s new Tegras. A new low-power MIT chip, however, may prove its worth by being a jack of all trades that works faster than software. It can apply HDR to photos and videos through near-immediate exposure bracketing, but it can also produce natural-looking flash images by combining the lit photo with an unassisted shot to fill in missing detail. Researchers further claim to have automatic noise reduction that safeguards detail through bilateral filtering, an established technique that uses brightness detection to avoid blurring edges. If you’re wondering whether or not MIT’s work will venture beyond the labs, don’t — the project was financed by contract manufacturing giant Foxconn, and it’s already catching the eye of Microsoft Research. As long as Foxconn maintains interest through to production, pristine mobile photography won’t be limited to a handful of devices.

The second screen has largely asked that you take your eyes away from the action, even if that is to play along in real-time. Visual SyncAR, however, brings that tablet or mobile right back into the thick of things. Developed by Japan’s NTT, the platform uses digital watermarksg that presents a timecode to the app running on the second device, allowing it to display content in sync with whatever is on the primary display. In the video after the break you can see the concept being illustrated with playful examples that interact with the program, but more useful applications include the ability for users to pull up subtitles for public information videos, or overlay sign language. Naturally, there’s also a massive potential for advertisers, who we’re sure would be more than keen to embrace the technology, and ably guide you from their commercial to an online outlet or additional promo material. Especially if they’re selling a cure for all that inevitable arm ache…
