Scientists prep mind reading device

Screaming to be heard: Boston University claims its mind-reading device can get inside the heads of paralyzed patients.

by Mark Baard

New Scientist magazine, cited by the Beeb in this report (link and excerpt, below), often exaggerates the nature of scientific findings and discoveries.

That’s why I am just a bit dubious of the claim that electrodes implanted in the brain of a speechless man are unlocking his thoughts, and relaying them to a voice synthesizer.

But if the scientists at Boston University can indeed guess the guy’s thoughts accurately 80 percent of the time, that would be impressive.

Once they take this technology wireless, calling our thoughts our own might prove impossible.

Scientists say they may be on the brink of translating the thoughts of a man who can no longer speak into words after a pioneering experiment.

Electrodes have been implanted in the brain of Eric Ramsay, who has been “locked in” – conscious but paralysed – since a car crash eight years ago.

These have been recording pulses in the areas of the brain involved in speech.

Now, New Scientist magazine reports, they are to use the signals he generates to create speech software.

Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay’s brain is imagining some 80% of the time
In the next few weeks, a computer will start the task of translating his thoughts into sounds.
“It’s very exciting that we are starting to be able to translate some basic thoughts, but we are lot further away from a universal mind reading machine than some people hoped – or feared – we may be five years ago.”

Urban wireless to serve intel and PSYOP forces

The government needs more nodes: Various agencies want to seed cities with wireless networking devices (image from a DOD document).

Despite the high costs and unproven social benefits for municipal broadband, dozens of U.S. cities are ignoring laws banning anti-competitive practices and getting into the internet business.

Meanwhile, the U.S. Department of Defense is planning to build robots that configure themselves into ad hoc wireless networks within urban areas.

City mayors claim they want to provide free and low-cost Wi-Fi access to the poor and attract business travelers. Defense planners say they need to have broadband capabilities in urban war zones.

But rather than closing the “digital divide” (which many academics admit is being exaggerated), or providing a redundant service to traveling salesmen, it appears that officials aim to seize control of internet communications and track individuals in urban areas.

Military and law enforcement agencies will also use the wireless networks to stage “hard PSYOP” attacks against a brain-chipped populace, according to historian and commentator Alan Watt, who specializes in secret societies and government intelligence operations.

Philadelphia, San Francisco, Houston, and Providence, R.I. are among the cities partnering with private companies and the federal government to set up public broadband internet access. Providence used Homeland Security funds to construct a network for police, which may be made available to the public at a later date.

None of the cities are expected to turn a profit anytime soon. Nor are the poor likely to benefit from the projects.

Subscribers to Philly’s “Wireless Philadelphia” service, for example, will pay up to 73 percent more than the rate promised to them two years ago.

“(Philadelphia) presented dangerously inaccurate estimates and figures for the costs and revenue” for its wireless network, according to a recent analysis by students at Harvard Law School. Continue reading

Helmet heads: devices connect AR with real world

Buggin’: One of the alternate reality headset designs at Holland’s AR+RFID Lab. The goal is to make the devices convenient and attractive enough to allow people to operate in both the real world and AR simultaneously.

IBM and Linden Labs (creators of the alternate reality Second Life) are developing headsets and other “wearable computing” devices to deliver humans into parallel realities, where they can control their experiences.Industrial designer's sketch from AR+RFID Lab

Linden Labs, for example, is developing a wearable speaker system that Second Lifers can use to communicate semi-privately in AR while continuing to function in the real world, at least at some basic level.

But at the moment, AR eyewear and headphones are typically bulky and expensive, and too distracting for the wearer.

Students at the AR+RFID Lab at the Royal Academy of Art in the Netherlands are shaping new designs for AR headsets (more below), to include cameras and projectors, and tracking devices. Continue reading

Dexter & Domo: all-American robo-dudes

Sensitive guys: New robots need a gentler touch

You can rock ‘em and sock ‘em and they’ll stay on their feet. The robots at Mountain View-based Anybots (see video clip below) are among those walking a bit more like humans. (We’ve seen most of these coming out of Japan and Korea, so perhaps U.S. roboticists are finally catching on to the need for robots beyond the battlefield.)

Roboticists are also giving their creations the ability to gently handle household objects and elderly people. A descendant of Domo, pictured above, may one day replace human caregivers, MIT announced today.

“If robots are ever going to be truly useful,” said MIT CSAIL director Rodney Brooks, “they need to be able to manipulate the objects we manipulate.”

GPS + WiFI + RFID = no place to hide

Prototype GPS module with built-in RFID tag (from Fujitsu)

I should have added “RFID” to the headline for my Globe column this week (clip and excerpt, below). It’s about how mobile phone companies can use WiFi triangulation to pick up your location when you are hidden from GPS sats.

But researchers at MIT and elsewhere are also combining GPS with RFID. That means companies and governments will not only be able to pinpoint your location, but determine which item you just pulled off a library shelf.

GPS + WiFi = no place to hide

Location Awareness
Even if you manage to avoid the watchful eye of those GPS sats, your laptop or smartphone may soon be visible to the Wi Fi Positioning System .

The positioning system, mapped out by Boston-based Skyhook Wireless, is a vast national database of public and private Wi Fi access points (16.5 million them) in 2,500 U S cities, including Boston.Now Skyhook is pairing WiFi Positioning System with GPS from SiRF Technology. The combined service will be available to the major wireless carriers this year

Toward a rubbier robot

If I read “once the stuff of science fiction,” in the lead of a science story on more time (it’s time for science writers to let go of that one)… well, anyway:

The New York Times today catches on to biomimetics, describing how Tufts researchers are working softer, wrigglier robots.

Robots That Slink and Squirm

Robots, once the stuff of science fiction, are everywhere. Robotic geologists are puttering around on Mars, little Roombas suck up dirt in the breakfast nook. But most robots are made up of hard components and don’t much resemble the creatures that walk, crawl and squirm all around us.
At Tufts University, a multidisciplinary team of researchers wants to take a softer approach. The Biomimetic Technologies for Soft-bodied Robots project is trying to make an ersatz caterpillar that will move around in pretty much the same way as the real thing.

The need to feel closer to our folks is driving the consulting firm Accenture to develop a system that makes those human connections via broadband data connections. Called the Virtual Family Dinner, it transmits your life-size video picture and voice to a special display setup in your folks’ kitchen, where you can join them for dinner. You will have to provide your own food.
