Researchers mod computer to copycat human motions

Webcams and video-conferencing software like Skype have really enhanced the way we communicate with friends, family, and colleagues around the world. Even so, talking to a floating head on a computer screen can still feel pretty cold, and it doesn't look like we're going to get a teleportation device any time soon (le sigh). However, researchers at Stanford University are hoping to make that interaction a little more lifelike with a computer that can mimic human motions.

David Sirkin and Wendy Ju from Stanford's Center for Design Research created a motorized flat-screen display that copycats various human motions like shrugging, nodding, and laughing. The team did so by adding motors to the Apple iMac G4 and then linking it to software that reads a person's movements and instructs the G4's moveable arm to perform one of nine motions. … Read more

Google X Labs: First Project Glass, next space elevators?

I will be probably the last person to use augmented reality specs from Google's Project Glass. But I have to applaud the company for taking on far-out concepts at Google X Labs.

Google today for the first time acknowledged Project Glass, in which an eyeglass-like frame essentially brings the Internet to a small screen above the right eye. The demonstration video shows, from the perspective of someone wearing the glasses, a person communicating with friends and looking up information just as he might use a smartphone.

Personally, I don't need any more distractions as I move through my … Read more

Early-warning software could reduce false alarms of seizures

Of the 50 million people worldwide estimated to have epilepsy, almost a third do not respond to treatment. Those patients must rely on implantable anti-seizure devices that detect pre-seizure electrical activity and shoot small electrical impulses to the brain to interrupt the seizures.

The downside is that the tech, still early in development, also produces false positives, causing devices to send currents to the brain when a seizure is not actually occurring. One new approach, developed by a biomedical and electrical engineer at Johns Hopkins University, appears to reduce those false alarms.

Tested on real-time recordings of brain activity in … Read more

Navy sets sail with robotics lab

The U.S. Navy is making autonomous robots a bigger part of its mission.

The Naval Research Laboratory yesterday announced the opening of the Laboratory for Autonomous Systems Research, an addition to the lab's campus in Washington, D.C.

The $17.7 million lab was created to allow scientists and engineers to test robotic devices in a range of environments where service members serve. It includes a simulated tropical rain forest in a greenhouse, a room with desert features, and a pool similar to near-shore waters.

The Navy, and the military in general, is one of the biggest drivers … Read more

LG bending limits of e-book design with flexible displays

It appears LG is making good on its promise to bring flexible displays to e-book readers, as the Korean consumer electronics company revealed that it has started mass production of the "world's first" plastic electronic paper display (EPD).

The screen measures 6 inches diagonally and has a resolution of 1,024x768 pixels. It can bend at a range of 40 degrees from the center of the screen, and it's also about one-third thinner and half as light as current glass EPDs, LG says, meaning it'll be even easier to carry than the e-book readers today.

LG also cites durability as a benefit of its plastic EPD. The company ran numerous stress tests on the display, including dropping it from a height of about 5 feet and hitting the screen with a small urethane hammer (how do I get this job?), and saw no damage. Presumably, this means you could toss your reader into your bag sans case without fear of scratching up the display. … Read more

Microbe helps convert solar power to liquid fuel

A new "bioreactor" could store electricity as liquid fuel with the help of a genetically engineered microbe and copious carbon dioxide. The idea -- dubbed "electrofuels" by a federal agency funding the research -- could offer electricity storage that would have the energy density of fuels such as gasoline. If it works, the hybrid bioelectric system would also offer a more efficient way of turning sunlight to fuel than growing plants and converting them into biofuel.

"The method provides a way to store electrical energy in a form that can be readily used as a … Read more

Use your fingers to frame shots with Ubi-Camera

If you want to get more natural with your pics, Japanese researchers are working on a gesture-based mini camera that lets your hands frame the shot.

The group at the Institute of Advanced Media Arts and Sciences (IAMAS) in Gifu Prefecture recently showed off something they call the Ubi-Camera, a play on "ubiquitous" and "yubi" ("finger" in Japanese).

As the vid shows below, the simple prototype attaches to your index finger while your other fingers form a viewfinder around it. Push a button with your thumb to snap the shot.

Instead of a zoom … Read more

Google artists create a real-time 'Wind Map'

Two technology artists who head Google's "Big Picture" visualization research group debuted a new project this week that shows a time-lapse animation of wind speeds across the U.S.

"An invisible, ancient source of energy surrounds us--energy that powered the first explorations of the world, and that may be a key to the future," the artists wrote in a post yesterday. "This map shows you the delicate tracery of wind flowing over the US right now."

The black map, simply named "Wind Map," displays white streaks that show varying wind speeds … Read more

Microfluidic chip to quickly diagnose the flu

During the H1N1 flu pandemic of 2009, which spread across more than 200 countries and killed more than 18,000 people, it became clear that flu diagnosis was often taking too long and resulting in frequent false negatives.

Today, researchers from Boston University, Harvard, and the Beth Israel Deaconess Medical Center are reporting in the journal PLoS ONE that they have built a microfluidic chip that rivals in accuracy the gold-standard diagnostic test known as RT-PCR but is faster, cheaper, and disposable.

For their four-year study, which involved 146 patients with flu-like symptoms and was funded by the National Institutes … Read more
