They only wanted to show their disapproval. Friends eager to counterbalance all those Facebook “Likes” rushed to “Download the official DISLIKE button now” as received in a message. But, sadly, no dislike button was in store. Instead, installing the application provided users with several surveys and left their profiles vulnerable to spammer control. If there was ever a time to unleash their Dislike, this was it.
Yet, as Graham Cluley of the security firm Sophos told the BBC–mentioning a similar ploy that offered Facebookers the chance to see an anaconda vomiting up a hippo–such “survey scam” applications are nothing new:
“Anyone can write a Facebook app–these scams are constantly springing up.”
Perhaps Facebook should take note: Users were willing to sacrifice their security for the mere power to express negative feedback. Or, at least, the mere power to express negative feedback without typing.
Perhaps a compromise is in order? Unfortunately, a new Meh button application seems to need some tweaking. As in the Atlantic Wire:
Turns out, every time you click the “meh” button it registers your vote—allowing an individual user to “meh” something 10,000 times or more. That’s a lot of indifference.
That grease trail you’ve smeared on your smart phone’s touchscreen could give away more than your lightsaber skills or virtual girlfriend’s whims: Would-be smudge attackers, a recent paper argues, could follow your finger oils as a clue to your passcode.
In the paper “Smudge Attacks on Smartphone Touchscreens,” which we first saw on Gizmodo, a team in the computer science department at the University of Pennsylvania tried to pick out grease patterns from Android phones by photographing the phones and enhancing the patterns with photo-editing software. From the paper’s introduction:
“We believe smudge attacks are a threat for three reasons. First, smudges are surprisingly persistent in time. Second, it is surprisingly difficult to incidentally obscure smudges through wiping or pocketing the device. Third and finally, collecting and analyzing oil residue smudges can be done with readily-available equipment such as a camera and a computer.”
Those subscribing to the iPad version of Playboy really will be reading it for the articles: The magazine has announced that it will forgo the naked women photos to conform to Apple’s stance against all apps deemed (pdf) obscene and pornographic.
The Telegraphreports that a “tasteful headshot” will greet iPad readers in place of the full glory of a playmate of the month, for example. Covering up (or cropping out) the skin will keep Playboy from that ever-growing list of app rejects, which formerly included one from a Pulitzer Prize-winning cartoonist.
Another app that escaped the banned list is My Virtual Girlfriend, which we found on the blog Neatorama. The game allows players to advance twenty “relationship levels” and apparently has a heart meter that you fill by engaging in activities like virtual hand-holding and virtual kissing. You can also thrill your virtual material girl by buying her shoes–she sounds like a real catch.
Though the Virtual Girlfriend disclaimer warns that the company is not responsible for any resulting marriages, we fear for anyone to whom that applies.
If your car could talk, it might tell you to stop texting. At least that’s what one research team hopes: after paying young drivers to perform texting-like games while driving a simulator, they found that visual warnings from an in-car “coach” helped keep drivers’ eyes on the road.
For high-risk drivers, the warning system “more than doubled their time until a virtual crash,” a University of Washington press release says. That might not sound entirely reassuring. But the researchers say a similar system installed on a real car might help risky drivers avoid a crash altogether.
A team led by Linda Ng Boyle, an industrial and systems engineer at the University of Washington, first had a group of 53 drivers, ages 18 to 21, attempt to drive a simulator while simultaneously playing a matching game. As an incentive to take the game seriously, they paid drivers according to the correct number of matches they made. The riskiest drivers took their eyes off the road for between two and a half to three seconds, compared to moderate and low-risk drivers who would glance off the road for less than two seconds during their longest glances.
We’ve asked augmented reality to help us drive, overcome our phobias, and put names to faces. Now we want cookies. Researchers at the University of Tokyo in Japan have devised a headset that can replace the appearance and smell of a plain cookie with tastier varieties including chocolate, almond, orange, maple, lemon, and cheese.
The group, led by Takuji Narumi, presented its research at the SIGGRAPH conference on computer graphics at the end of last month. “Augmented gustation” is a challenge, the team says, because taste relies on so many of our other senses. We see the embedded chocolate chips. We smell the straight-out-of-the-oven scent.
The “meta cookie” project attempts to use our multiple cookie senses to create a virtual cookie variety pack. Users choose their preferred cookie, and a camera on the headset overlays an image on a plain sugar cookie and sprays the correct associated scent, be it maple or cheese. The closer the cookie gets to the user’s mouth, the more of the scent the headset cranks out. Though the test subject in the video above appears satisfied, TechNewsDailyreports that the trick did not fool everyone. One cookie remained “mostly neutral” tasting though the headset tried to conjure maple and chocolate flavors.
Perhaps researchers will next attempt to copy the cookie’s feel? Texture seems to matter: ask anyone who’s entered the crunchy versus chewy fray.
Tired of the faceless urbanites crowding their Google Street Views, computer scientists aimed to remove the pedestrians entirely. The images above show they succeeded, mostly.
The software was developed by Arturo Flores of the University of California, San Diego; earlier this summer he unveiled (pdf) the proof-of-concept. It’s built off of a previous algorithm developed in 2005 that can pick out pedestrians in urban settings. The new program removes the identified pedestrian and covers the gap using pixels from slightly ahead and slightly behind what appears to be someone walking down the street. But it only works in cities (where tall buildings give a relatively flat backdrop), can create a human smear when the photographed person walked at the same speed as the Google camera, and, one could imagine, has trouble in huge crowds–where neighboring pixel-swapping might result in blurry Frankenhumans.
But otherwise, it leaves a non-distracting, relatively “ghost free” image, a university press release says, that will further protect pedestrian privacy. When it almost succeeds, it gives users a good laugh: a post-apocalyptic cityscape including disembodied feet, ownerless dogs, and floating umbrellas.
Scientists are eyeing the future of solar technology–specifically, fly eyes. Turns out those bubbly-looking spectators might be just the ticket to more-efficient solar cells, researchers from Penn State University say.
Blowflies have peepers that would help solar panels collect light more efficiently, and creating these fly-eye molds was a feat in itself, according to Discovery News. After plucking the corneas from blowflies,
Add one more job to the list–along with vacuuming floors and assisting in surgeries, now robots can try on clothes for you. The company Fits.me is developing a robotic torso for online shoppers that can morph to match shoppers’ body dimensions, creating virtual fitting rooms on clothing websites.
Men can try a demo version of the product on the company’s site. After entering measurements such as neck and waste size, and selecting from three torso types, the site displays what you might look like in a particular shirt. The torso doesn’t morph in real time; instead, the site pulls from a database of pictures–2,000 body size combinations, the company reports, systematically showing users if pinstripes in small, medium, or large will make them look fat. Shirt sellers Hawes and Curtis is already testing a version of the system on their site.
As reported by the BBC, the company next hopes to develop a version of the torso for women. Maarja Kruusma a professor of biorobotics at the University of Tallinn who helped the company develop the system, told the BBC that it’s a difficult task. Women’s clothing comes in more intricate styles, and their torsos are more complicated to model, she says:
“You can’t just take a male mannequin and put breasts on it. That doesn’t work.”
Benjamin Franklin would be proud. The tinkerer who loved playing with electricity and allegedly invented the bifocals might have been glad to know that one company has now brought the two things together: PixelOptics has designed a pair of powered specs that can track users’ eyes and automatically adjust the glasses’ focal length, depending on if the wearer needs to see close-up or far-away.
The glasses use liquid crystals, which can change how much they bend light when an electrical current runs through them. A video demonstration of what a wearer might see is available on PixelOptics’ website, and the company hopes that the glasses will be available in the United States before the end of 2010.
Peter Zieman, director of European sales for PixelOptics, said the device uses motion tracking software similar to the iPhone, and toldThe Telegraph:
