Soldiers barking orders at each other is so
20th Century. That's why the U.S. Army has just awarded a $4 million contract
to begin developing "thought helmets" that would harness silent brain
waves for secure communication among troops. Ultimately, the Army hopes the
project will "lead to direct mental control of military systems by thought
alone."
If this sounds insane, it would have been as recently as a few
years ago. But improvements in computing power and a better understanding of how
the brain works have scientists busy hunting for the distinctive neural
fingerprints that flash through a brain when a person is talking to himself.
The Army's initial goal is to capture those brain waves with incredibly
sophisticated software that then translates the waves into audible radio
messages for other troops in the field. "It'd be radio without a
microphone, " says Dr. Elmar Schmeisser, the Army neuroscientist
overseeing the program. "Because soldiers are already trained to talk in
clean, clear and formulaic ways, it would be a very small step to have them
think that way."
B-movie buffs may recall that Clint Eastwood used similar
"brain-computer interface" technology in 1982's Firefox, named for the Soviet fighter
plane whose weapons were controlled by the pilot's thoughts. (Clint was sent to
steal the plane, natch.) Yet it's not as far-fetched as you might think: video
gamers are eagerly awaiting a crude commercial version of brain wave technology
— a $299 headset from San Francisco-based Emotiv Systems — in
summer 2009.
The Army doesn't move quite as fast as gamers though. The
military's vastly more sophisticated system may be a decade or two away from
reality, let alone implementation. The five-year contract it awarded last month
to a coalition of scientists from the University of California at Irvine,
Carnegie Mellon University, and the University of Maryland, seeks to
"decode the activity in brain networks" so that a soldier could radio
commands to one or many comrades by thinking of the message he wanted to relay
and who should get it. Initially, the recipients would most likely hear
transmissions rendered by a robotic voice via earphones. But scientists
eventually hope to deliver a version in which commands are rendered in the
speaker's voice and indicate the speaker's distance and direction from the
listener.
"Having a soldier gain the ability to communicate without
any overt movement would be invaluable both in the battlefield as well as in
combat casualty care," the Army said in last year's contract solicitation.
"It would provide a revolutionary technology for silent communication and
orientation that is inherently immune to external environmental sound and
light."
The key challenge will be to develop software able to pinpoint
the speech-related brain waves picked up by the 128-sensor array that
ultimately will be buried inside a helmet. Those sensors detect the minute
electrical charges generated by nerve pathways in the brain when thinking
occurs. The sensors will generate an electroencephalogram — a confusing
pile of squiggles on a computer screen — that scientists will study to
find those vital to communicating. "We think we can train a computer to
understand those squiggles to the point that they can read off the commands
that your brain is issuing to your mouth and lips," Schmeisser says.
Unfortunately, it's not a matter of finding the single right squiggle.
"There's no golden neuron that's talking," he says.
Dr. Mike D'Zmura of UC-Irvine, the lead scientist on the
project, says his task is akin to finding the right strands on a plate full of
pasta. "You need to pick out the relevant pieces of spaghetti," he
says, "and sometimes they have to be torn apart and re-attached to
others." But with ever-increasing computing power the task can be done in
real time, he says. Users also will have to be trained to think loudly.
"How do we get a person to think something to themselves in a way that
leaves a very strong signal in EEGs that we can read off against the background
noise?" D'Zmura asks. Finally, because every person's EEG is different,
persons using "thought helmets" will have to be trained so that
computers intercepting their unspoken commands recognize each user's unique
mental pattern.
Both scientists pre-emptively deny expected charges that
they're literally messing with soldiers' minds. "A lot of people interpret
wires coming out of the head as some sort of mind reading," D'Zmura sighs.
"But there's no way you can get there from here," Schmeisser insists.
"Not only do you have to be willing, but since your brain is unique, you
have to train the system to read your mind — so it's impossible to do it
against someone's will and without their active and sustained
cooperation."
And don't overlook potential civilian benefits. "How often
have you been annoyed by people screaming into their cell phones?"
Schmeisser asks. "What if instead of their Bluetooth earpiece it was a
Bluetooth headpiece and their mouth is shut and there's blessed silence all
around you?" Sounds like one of those rare slices of the
