Contact Lenses Could Send Texts to Your Eyes

Contact_lens

Belgian technologists just created curved liquid crystal display for contact lenses, a novel step toward having augmented reality literally right before our eyes. They've got an eye on displaying text messages this way.

Unlike previous developments in contact lens displays, University of Ghent researcher Jelle De Smet focused on creating a curved LCD that would be incorporated into a contact lens rather than embedding LED technology into one. This approach means De Smet and his colleagues at the Center of Microsystems Technology have a larger display area, according to the university.

Hack Yourself A Super Secret LCD Monitor

The group achieved their curved display by using extremely thin conductive polymer films that were integrated into a smooth spherical cell. Resembling an old-school calculator display, their first prototype can show basic patterns like a dollar sign that recalls cartoon characters thinking about money.

While onlookers could potentially see the symbols being displayed in someone else's contacts, the wearer would still have problems viewing them. As University of Washington's Babak Amir Parviz explained to me last year while describing his computerized contact lens development, humans have a mimimum focal distance for even seeing a single pixel.

The Belgian team seems to understand that limitation, indicating in a university press release that the initial applications for their liquid crystal-based contact lens display might be to help control light transmission in people with damaged irises or replace colored contacts, allowing wearers to change the color or pattern on the go. They also imagine these contacts working as adaptable sunglasses.

Here's a video from De Smet that shows the thin, curved display working in the lab:

Since the lenses can project images sent to them wirelessly, the potential is there for these displays to show directions or even texts from a smart phones. "This is not science fiction," De Smet told The Telegraph's Bruno Waterfield recently, adding he expects commercial applications will be available within five years.

Being so myopic myself, I'm cautious about the prospect of extra functionality in my contacts. At least if there's a problem with your phone you can restart it. Removing contacts would get really annoying, especially if you're on the road.

I admire De Smet's enthusiasm about one day getting text sent straight into our eyes. Whether we'll actually be able to read them remains to be seen.

5 Breakthroughs For Gadgets In 2012

Innovations-2012-622-x505

Innovation in the gadget business rarely comes in great leaps forward. Most of the time, somebody will take an existing idea and implement it at a cheaper cost, at a larger scale or in a new context, and that change is enough to shake up our sense of what technology can do.

And that's exactly what these five breakthroughs have done for me this year.

1. "Retina displays" grow up, and out. Two years after Apple's iPhone 4 introduced a display so sharp that you could no longer distinguish its constituent pixels, "Retina displays" started showing up in the Cupertino company's other gadgets (and many competing smartphones). On this spring's iPad, the results were amazing, instantly making the old model's screen look bad.

But on Apple's laptops, Retina displays have jacked up prices substantially. And on flat-panel TVs, ultra-high-resolution "4K" and "8K" resolution suffers from the fact that at typical couch-viewing distance, even mere HD resolution can exceed our visual acuity.

2. Cheaper smartphone service. This year, the cost of keeping a new smartphone finally started ratcheting down in a big way. The prepaid carrier Cricket Wireless slashed the monthly bill for an iPhone to $55, then its competitor Virgin Mobile beat even that with a $30 deal.

Among the four major carriers, Verizon Wireless may have hiked its rates but T-Mobile has gone in the other direction with "value" plans that subtract the usual subsidy of a cheaper phone price, meaning you save more over time. And next year, that carrier will make that its standard.

3. Affordable gigabit broadband. While most Americans are stuck with the same one or two broadband Internet providers as ever, a lucky few can now sign up for breathtakingly faster connections at prices no higher than a low-end cable bill: Sonic.net charges just $70 for gigabit (1 billion bits per second) service in parts of the Bay Area, a price matched by Google's gigabit-fiber service in Kansas City.

Sure, most of us can't use those speeds. But imagine what the arrival of gigabit access for under $100 would do to your own ISP's pricing... or don't, if you'd rather not depress yourself.

4. Smarter shared transportation. Near-ubiquitous wireless-data service and cheap GPS sensors are making it easier and cheaper to get around cities without having to own your own ride. Among the most interesting such options: car2go, which broke out of its Austin test market this year with a launch in Washington this spring, followed by expansion to Miami, Portland, San Diego and Seattle. It allows you to rent a Smart fortwo at a cheap, per-minute rate and then park it on the street for free -- in effect, making it a longer-distance complement to bicycle-sharing services like D.C.'s Capital Bikeshare.

I'm equally fascinated by startups that make better use of transportation we've already paid for, such as the Uber sedan-ride service. But when these involve privately-owned conveyances -- for instance, Lyft's carpooling -- they can run into legal hangups.

5. The Internet winning in Washington. One of the tech business's most promising developments didn't involve software code or circuit boards. But the way Internet users rebelled at the offensive overreach of the Stop Online Piracy Act, which would have broken the Net's basic routing system and allowed copyright holders to unplug the finances of allegedly infrinting websites pretty much at will, mattered anyway.

"SOPA" had the backing of some of Washington's most entrenched interests, but individual citizens who didn't want to see technology criminalized overcame all of it. That's good news for continued innovation, both next year and over the next decade.

Paper USB Drive Is Disposable

IGG2

Despite a lot of talk about society going paperless, paper is still around. Humans still hand out paper versions of business cards, birthday cards, invitations and resumes. Corporations still send direct mail and catalogs to consumers. Intellipaper is a project on Indiegogo that's looking to add a whole lot of info to that paper, without taking up more space.

NEWS: Submarine for the Luxury Crowd

The developers have created a way to embed a silicon chip into regular paper to make a disposable paper USB drive. It can be inserted into any computer's USB port to share websites, personal information, images  or portfolios. The USB drive can be customized to fit any paper-based item you want, be it greeting cards, business cards or even wedding invites with registry info embedded for easy access. If fully funded on Indiegogo, the project could be a much cooler version of the QR code.

The project is currently seeking funding, but they hope to release a reader/writer device that will be able to create USB drives with whatever content a user wants and read pre-embedded paper. Depending on what tier a pledger chooses they could receive pre-embedded paper and a reader/writer.

Comics Journalism Hits the Tablets

Symbolia-278x225

You've heard of comic books; you've heard of magazines. Now a new generation of journalists is merging the two to tell non-fiction stories about everything from environmental destruction in California and the mysteries of the Congo River to our gut's microbiome and an obscure psychedelic band from Zambia.

The merger has resulted in a new tablet-based magazine called Symbolia, which was launched this week. Unlike text-heavy narratives that readers may find in magazines such as the Atlantic or the New Yorker, this new digital experience tells stories in illustrated, interactive panels.

For example, one feature story -- "Live Long, Die Quick" -- opens with an illustration of Chinese microbiologist Zhao Liping wondering if tailoring his diet to the microbes in his stomach could help him loose weight.

The subsequent panels show that by eating Chinese yam and bitter lemon, Zhao can tweak his microbial makeup and slim down. There's animation, including wiggling microbes and tappable infographics, so the users can choose how deep they want to dive into the story.

Founded by Chicago-based journalist, media consultant and comic enthusiast Erin Polgreen, Symbolia is to journalism what the graphic novel is to literature.

NEWS: Nanoprinter Achieves Insane Resolution

Traditional media such as newspapers and magazines continue to tailspin as they struggle for identity in the digital age. While Symbolia isn't seeking to replace the old guard, it recognizes that a fresh voice needs to be brought into the arena.

Symbolia started about three years ago when Polgreen said she began noticing a new crop of comics creators who were also doing journalism.

"I was really into the work Sarah Glidden,Ted Rall and Matt Bors had been doing, specifically because they had been using Kickstarter to fund trips for non-fiction comics on conflict zones," Polgreen told Discovery News. "They had been quite successful."

Not only that, these non-fiction story tellers were flying completely under the radar of traditional news organizations.

And then one day, Polgreen said she had a "kapow moment."

"I was reading an issue of Wonder Woman, then I switched over to reading a magazine on my new iPad I got off of Craigslist," Polgreen said. "Everything just kind of clicked together, like picking a lock. That's our origin story, if you will."

Polgreen applied for and received a couple of grants -- one from J-Lab and the McCormick Foundation's New Media Women Entrepreneurs program and the other from the International Women's Media Foundation -- that helped transform her idea of into a fully-developed tablet magazine of illustrated journalism.

PHOTOS: Tech That Brings the Family Together

Symbolia's first issue was launched on Monday, Dec. 3, and is available free, either as an interactive iPad app (an Android app may soon follow) or in PDF form. Starting in 2013, it will be published every other month and cost $11.99 for six issues.

Polgreen's goal up front is to use clever design, great color and visual narrative devices to talk about complicated issues. She says she wants to bring a fresh energy back into storytelling, one that isn't always evident with text-heavy content.

"Comics journalism represents not only this opportunity to be playful, fun and have a cozy hand-crafted feel to your product, but it's also this way to bring more people in. You bring in more visual learners -- people who think about things or interact in different ways than someone who might read 10,000 words of text," Polgreen said.

She cites one of the most widely circulated newspapers in the United States as an example of how a more visual format can appeal to readers.

"When USA Today started out, people pooh-poohed that they had infographics and thought the paper was speaking down to the masses," Polgreen said. "But it's one of the papers that's still around. I don't think they're on fabulous financial footing but they broke the wave of varying design in news."

John Fennell, an associate professor at the Missouri School of Journalism who is heavily involved with the weekly, student-run Vox Magazine, said he thinks Symbolia could be another wave-breaker.

“We study news and magazine startups and try to understand what’s working and what’s not," he said. "I have to say, Symbolia is the freshest startup I’ve seen in a long time."

New magazines come into the fold all the time and it's a constant experiment within the industry to see which ones will stick, says Fennell.

“We’re in this cycle where we can pick up news anywhere and that’s why magazines like Newsweek have folded and Time is seeing some difficulties," he said. "So when you get something like” Symbolia, “where it’s a combination of something that no one’s ever done before, I think it’s worth paying attention to.”

Even with slick design, sharp reporting and engaging storytelling, Polgreen understands how difficult it is to remain profitable in today's media landscape. However, she believes her loyal audience -- a Venn diagram of journalists, nerds, technologists and comic fans -- will do more than just save the day.

"One of the reasons I thought I could really make a go with Symbolia as an actual business venture is I've been watching web comics for the last 10 to 15 years grow into entities that actually support their creators full-time," Polgreen said.

Fennell agrees.

“All successful magazines have niche audiences. General-interest magazines just aren’t working anymore,” he said. With Symbolia, “here you have a built-in audience -- a loyal audience -- that likes graphics and knows the subject of graphic novels and literature.”

The magazine industry may be on shaky ground, but for Polgreen, this built-in audience is the cornerstone of what she hopes will be Symbolia's solid foundation.

"Comics fans are wonderfully supportive of the people and art that they love. There's a very strong emotional connection," she said. "It's my hope to bring in more people who read comics on a regular basis and help them engage more with news and what's happening in the world."

Fox Steals Mobile Phone, Sends Text

Fox_cell_phone

When a fox nabbed Norwegian teenager Lars Andreas Bjercke's cell phone and stole away into the woods, the 16-year-old didn't anticipate hearing back from the furry animal. But that's what happened.

Bjercke had downloaded an app on his smartphone to make it emit rabbit noises, according to the site LiveLeak.com. Then he played the phone in his yard, prompting a local fox to circle the yard in response over the course of several nights.

Ginormous Armed Robot Controlled by Phone

Bjercke and his friend Sigurd Grønvik Bachke decided to see what they could capture on video. With Bachke filming, Bjercke put his smartphone on the ground and the two watched as the fox investigated what must seem like very strange prey:

After the fox nabbed the smartphone, Bachke tried calling it using his own. According to the Norwegian newspaper Verdens Gang (in Norwegian), the fox apparently answered.

Bachke told the paper he heard something crunch like the fox was fiddling with the phone and then they listened for about five minutes. At first the kids thought it was funny until they remembered that the fox still had Bjercke's smartphone...somewhere. That's lame, they thought.

Then, a day after the fox took the device, one of Bjercke's friends contacted him through Facebook to say she'd received a weird text message from his phone: "jlv I øi\a0ab 34348tu åaugjoi zølbmosdji jsøg ijio sjiw." Fox language isn't on Google Translate yet, unfortunately.

Since then, Bjercke has turned off his lost phone but told Verdens Gang reporters that he still hopes to find it one day. Who knows -- maybe the fox snapped some pics, too.

Pope Brings Twitter Closer to God: DNews Nugget

Dnews-nuggets-278x225Pope Brings Twitter Closer to God:

Pope Benedict XVI will tweet regularly in eight languages from the account @pontifex starting Dec. 12, just in time for Christmas, the Vatican said on Monday.

"The first tweets will be answers to questions sent to the pope on matters of faith. The public can start sending them starting now," the Vatican said.

The account already has 2,435 followers, with numbers rising quickly immediately after the announcement. An introductory message read: "Welcome to the official Twitter page of His Holiness Pope Benedict XVI."

The tweets will be in Arabic, English, French, German, Italian, Polish, Portuguese and Spanish and more languages could be added in future.

"The pope's presence on Twitter is a concrete expression of his conviction that the Church must be present in the digital arena," the Vatican said in a statement. It added that Benedict wanted "to ensure that the good news of Jesus Christ and the teaching of his Church is permeating the forum of exchange and dialogue that is being created by social media".

Several leading Vatican prelates are already regular tweeters including Cardinal Gianfranco Ravasi, head of the Pontifical Council for Culture, as the tradition-bound institution tries to reach a younger global audience.

Benedict last year launched a new Vatican information portal with a tweet from the Holy See's Twitter account sent from an iPad. A bemused pope could be seen in images of the event being shown by prelates how to tap on the device. via AFP

Touch Screen Desks For Next-Gen Schools

StartrekThere are some projects proposed for the future that can make you roll your eyes, and others that make you say, "Can we have this now, please?" The NumberNet desk belongs in the latter category.

Researchers from Durham University have been testing out the multi-touch, multi-user desk as part of a three-year project with over 400 students. The students range from ages eight to ten and use the desk in a group setting. Using the desk in this way allows the students to solve mathematical questions by working together and collaborating on one large platform rather than on multiple sheets of paper.

NEWS: Vampire Algae Suck on Salad

Much like other multi-touch desks on the market, this one has been designed to recognize multiple touches on its desktop using infrared lights. These screens have been built into existing fabric and furniture in the classroom and are linked to a main smart board controlled by a teacher. Because of this control, a teacher can use the screen as a lecture piece as well. Which means no Power Point or whiteboard and no more peeking over screen-covering tall kids. Solutions and input from other students can be shared to other groups by the teacher through the screens.

So far the project has found that the children who collaborated together showed improvement in mathematical flexibility and fluency, compared to those who used paper-based methods. The lead researcher of the project, Liz Burd says that the whole point of the project is to encourage more active student engagement, "where knowledge is obtained by sharing, problem-solving and creating, rather than by passive listening."

If implemented, this method of learning would encourage participation from all students, and not just one smarty-pants. Only mathematics was testing in this project, but researchers say that it could be applied in other areas of learning as well.

Utensil Texture Affects Taste of Food

Jeontable

For some reason, I still remember what it felt like to be fed from a spoon when I was a baby. It probably has something to do with the tactile sensation from a coated spoon made special for baby teeth. For a brief moment, I was reminded of those spoons when I saw the project "Tableware as Sensorial Stimuli" from design student Jinhyun Jeon.

The designer was inspired by the neurological condition synesthesia. This condition causes each sense to affect or be triggered by the other. For example, certain smells make a person with synesthesia see a specific color.

NEWS: Eating Tofu Could Improve Your Sex Life

The utensils created for this project were done so to support a thesis about the relationship between the way food tastes and the tactile sensations from the tools used to eat it. A table setting that uses these forks and spoons looks like a futuristic exhibit of alien dinnerware. The spoons are covered in different types of textures and colors, from knobby edges to smooth pink ceramic.

They also vary in weight, volume and shape. According to Jeon, warmer colors like red increase appetite and different textures can stimulate the sense of touch in the mouth, which can affect the way food tastes.

Bill Gives Feds Warrantless Email Surveillance

Email-surveillance-622

A Senate proposal originally drafted to protect American's email privacy has taken a dramatic detour. In fact, it's turning around and heading in the opposite direction.

The original bill, backed by Democratic chairman of the Senate Judiciary committee Patrick Leahy, required that government agencies obtain search warrants before accessing email accounts. According to CNET's Declan McCullagh, a new version of the bill does away with all the middle men and actually gives government agencies warrantless access to Americans' email accounts. The bill is up for vote next Thursday (November 29.)

PHOTOS: 10 Trickiest Spy Gadgets Ever

Leahy's revision would give more than 22  government agencies access to email, Google Docs files, Facebook posts, even Twitter direct messages, without probable cause. In some scenarios, the bill also gives the FBI and Homeland Security full access to Internet accounts without the approval of the owner or a judge.

Law enforcement groups, such as the National District Attorney's Association, and Justice Department officials objected to Leahy's original bill. Detractors worried that requiring a warrant to access email accounts could impede criminal investigations.

Citing ongoing legislature discussions, an aide to the Senate Judiciary committee declined CNET a comment on the matter. In light of former CIA director David Petraeus' email scandal, Marc Rotenberg, head of the Electronic Privacy Information Center, did tell CNET that "even the Department of Justice should concede that there's a need for more judicial oversight," not less.

Agencies granted this warrantless surveillance power include any executive department, military department, government corporation, government-controlled corporation or other establishment in the executive branch of the government. Also included is a long list of independent regulatory agencies, such as the Federal Reserve System, the Federal Trade Commission (FTC) and the Federal Communications Commission, just to name a few.

BLOG: Government Surveillance On Citizens Rising

Such a hodgepodge list has rankled Markham Erickson, a lawyer in Washington D.C. who has kept a close eye on the legislation. Speaking not for his corporate clients, Erickson aired his concerns to CNET:

There is no good legal reason why federal regulatory agencies such as the [National Labor Relations Board], [Occupational Safety and Health Review Commission], [Securities and Exchange Commission] or FTC need to access customer information service providers with a mere subpoena. If those agencies feel they do not have the tools to do their jobs adequately, they should work with the appropriate authorizing committees to explore solutions. The Senate Judiciary committee is really not in a position to adequately make those determinations.

In many cases, police will still be required to obtain search warrants -- except when an "emergency" situation is declared -- but the new bill is in stark contrast to the original draft. Tech companies are likely to furrow their brow over these new proposals. What about you?
