PALO ALTO, Calif., May 27 — For anyone who has hesitated before making a purchase on a Web site, uncertain which brand is preferable, Tacit Software is preparing to introduce an online service that will make it simple to pick the brains of friends and colleagues for opinions and expertise.
Tacit plans to start testing the service, called Illumio, next month. The service allows the user to mine the data on the computers of friends, business associates and others with shared interests on any subjects.
However, Illumio is not a search engine, like Google or Yahoo. The system works by transparently distributing a request for information on questions like "Who knows John Smith?" and "Are Nikon digital cameras better than Olympus?" to the computers in a network of users. The questions can then be answered locally based on a novel reverse auction system that Illumio uses to determine who the experts are.
The system is intended to extend a growing category of software that helps groups collaborate and work together more efficiently. Efforts to create systems that augment the intellectual power of work groups go back to the earliest days of computing technology development. The widespread availability of networks and Web browsers, however, has made such technologies far more accessible in recent years.
"The collaboration space is big and busy," said David L. Gilmour, president and chief executive of Tacit. "We don't consider ourselves a collaboration environment, rather we are about communication and search."
Currently, the privately held Tacit, which was founded in 1997, sells similar technology, known as ActiveNet, to corporate customers like Lockheed Martin, Northrop Grumman, Morgan Stanley and Sanofi-Aventis. The new Illumio version is intended to be used over the open Internet. It will be free for individual users and sold commercially to private groups, although the company has not announced pricing.
Software such as Illumio is representative of the rapid emergence of new markets for digital information, said Michael Schrage, a researcher at the Massachusetts Institute of Technology Sloan School of Management.
"This represents the eBayification of organizations," he said. "The reality is that organizations are run off of informal connections and tools such as this facilitate gray markets in information and interpersonal exchange."
Tacit's top achievement in its software for connecting people and expertise may be in a design that keeps personal information private.
"The biggest problem we had to solve was the privacy problem," Mr. Gilmour said.
Because the information used to determine if someone is an expert on a particular question stays on local computers, Tacit's executives said Illumio would avoid potentially troubling privacy questions. The Illumio software is installed on users' PC's, where it is connected through a software interface to either Microsoft or Google's desktop search programs that index local user content, including documents and electronic mail.
The anonymity offered by Illumio is a significant advantage over other social networking software services that place pressure on users to offer assistance.
The Illumio software uses a reverse auction model to restrict the answer to the best expert. In a reverse auction, sellers compete for the right to provide goods or services. For example, in response to the question, "Who knows John Smith?" each Illumio local system would independently determine who had the best relationship in the network based on parameters such as who had recently exchanged the most e-mail with John Smith.
If the local system found a strong relationship, the local Illumio client software would pop up a request on that user's screen asking whether the user wished to respond to the person asking the question. Initially only the strongest candidates would be notified locally of the query. If that user ignored the request, the reverse auction system would, in effect, lower the bar to ask the person with the next strongest relationship. Then, if there were no responses, the bar would be again lowered until an expert responded. It is possible that difficult questions would find no experts.
The system insures that experts remain anonymous until they agree to answer the query. When a user answers, the connection is made either through the Illumio system, by e-mail or by other channels such as instant messaging or telephone.
In addition to the keywords that make up the question, a user is permitted to send an accompanying message that will help people determine whether they have relevant information to a particular question.
Tacit hopes to market the service by providing Web masters with icons it calls "hot spots." For example, a person running a digital photography or similar Web site could place a hot spot on its home page and then anybody who wanted to join an Illumio network on digital photography could do so by simply clicking on the link.
If they already had the Illumio software, it would automatically add them to the group. If not, it would download and install both the indexing software and the Illumio client software. Illumio is currently available for Windows-based computers.
The potential of Illumio lies in its ability to help small groups of friends and associates tap expertise that they might otherwise not know existed, said Esther Dyson, publisher of Release 1.0, a computer industry newsletter and an Illumio investor. "This is searching your friends' heads as reflected in what's on their computers," Ms. Dyson said.
Yet research on multiple fronts in digital technology, biotechnology and nanotechnology may, over the next half century, alter the way we think about computers and information, and our relationship to them. With these changes, bionic body parts won't seem so far-fetched as we increasingly develop ways to integrate high-tech materials into our mortal flesh.
And the reverse is true as well. Researchers are now looking to biological materials such as bacteria, viruses, proteins and DNA to replace mechanical parts in computers. And as the age of genetic engineering matures, scientists are already borrowing techniques from software developers to build libraries of genetic information.
All of these overlapping strands of scientific inquiry are known colloquially as "BANG," which stands for bits, atoms, neurons and genes. "All these things are converging because biology, nanotech and organic chemistry are running together," says Mark Bunger, an analyst with Lux Research. "The boundaries are really getting sketchy."
Some of the advances are in the earliest phases of research and won't produce actual products for years, if at all. But some of these concepts have quietly been with us for years. Sixty thousand people worldwide, for example, have cochlear implants, surgically implanted devices that do electronically what the ear can no longer do naturally--transform vibrations into signals the brain interprets as sound. Prosthetic limbs are increasing in sophistication. And now, tech applications are making their way into other parts of the human body.
Mind control
One of the best examples from this new
world where man meets machine, and biology and digital technology come
together with stunning results, occurred in an unassuming young man
from the suburbs south of Boston.
Matthew Nagle was a normal American guy who played football in high school and loved his local teams. A few years after graduation, he was looking into a job with the U.S. Postal Service--until a July night in 2001 when he was knifed in the neck during a fight at the beach. The blow severed his spinal cord and left him paralyzed from the neck down.
Young, optimistic and otherwise healthy, Nagle at age 24 volunteered to be a human guinea pig--the first recipient of an implant developed at Brown University. Nagle spent a year connected to the BrainGate system, with a chip the size of a lentil resting on a part of his brain that controls motor functions. The chip, 16 millimeters square with 100 gold spikes on it, was sensitive enough to pick up Matt's brain activity when he thought about movement.
The chip was connected to a cable that emerged from the top of Matt's skull and into a contraption that resembled devices from "The Matrix" movies. In those films, Keanu Reeves is hooked up to a computer from a box in the back of his neck, which downloads intelligence into him. ("Whoa," he says upon waking. "I know kung fu.") Nagle's connection went the other way; the implant uploaded brain signals into a software program that, with some tweaking, learned to interpret what they meant.
Here's how it works: When the patient's neurons fire, electrodes pick up the electrical activity; when the neurons are firing well, they generate electrical "spikes." The software reads these spikes as "movement intention."
Elizabeth Razee, a spokeswoman for Cyberkinetics Neurotechnology
Systems, which ran the BrainGate trial, describes the process. "When
you want to move your arm up and to the left, for example, the neurons
on your motor cortex actually fire in a specific sequence. The computer
software reads that intention and translates it into cursor action on
the screen 'up and to the left.'"
Nagle quickly learned how to control an on-screen cursor and other visual interfaces, such as a "Pong" paddle, with his mind. The footage is surreal. Nagle sits immobile in his wheelchair, speaking with the aid of a ventilator and playing "Pong" or "Tetris" or changing channels on a TV.
Nagle's year with the BrainGate ended last fall, and the implant has now been removed, but Cyberkinetics provided archive video and interviews with Nagle. "It's kind of a trip to think that my brain signals were controlling a mouse," he says. "Who knows, in two or three years, they might put it back in. I'd do it all over again. It did a lot of good."
Lou Gehrig's disease
Cyberkinetics now has another
spinal cord patient using BrainGate, but unlike Nagle the new patient
has chosen to remain anonymous. The company says the next step is to
test the system with patients suffering from amyotrophic lateral
sclerosis, or ALS, also known as Lou Gehrig's disease, named after the
New York Yankee who retired in 1939 after his diagnosis and died two
years later.
ALS patients slowly get "locked" into their own bodies. They remain cognitive, but their muscle and motor functions are cruelly stripped away, including the ability to communicate with the outside world, leaving only their hearing and vision intact. Many die because they can no longer breathe.
Researchers in Boston are recruiting patients for the BrainGate ALS trials, but with the leap in complexity from spinal cord injury, or SCI, to ALS, success is far from assured. "ALS patients often come to me and say, 'I've learned about (BrainGate), why aren't we doing this?'" says the ALS Association's science director, Lucie Bruijn. "You have to appreciate that with SCI. There's an injury in one area, (but) then there's not much progression. ALS is diffuse. It affects motor neurons throughout the body, and it's progressive."
One ALS specialist who advised on the design of the upcoming BrainGate trial says applying the technology to fight ALS is much more of a leap into the unknown. Primate studies that may give guidance aren't possible with ALS, says Dr. Merit Cudkowicz of Partners HealthCare System. "They can model spinal cord injury in monkeys, but no one will develop primate models for ALS. It's such a horrible disease. There's no shortcut to going straight to people."
Hundreds of researchers around the world are working on various aspects of this brain-computer interface, including noninvasive systems such as caps full of electrodes that pick up brain activity through the skull. Prominent participating institutions include Duke University's Nicolelis Lab, the state of New York's Wadsworth Center in Albany and the Cleveland Clinic. In Europe, the Graz University of Technology in Austria has a brain-computer interface lab. In Japan, where ALS patients are living longer and progressing more deeply into the "locked in" phase, corporations such as Hitachi have joined forces with university researchers.
Biocomputing
Less miraculous than helping paralyzed
people use mind control, but just as far-reaching, is the future of
computers themselves. Various research disciplines, each in itself a
vast and complex area of knowledge, are looking ahead to a day when we
reach the physical limitations of current computers and their
components: silicon chips, metal batteries, cathode-ray monitors.
Some of these limitations come from the materials themselves. Silicon and other semiconductors begin to lose key properties, such as temperature control, as components shrink. But other constraints are a function of the interface between humans and computers. Anyone who has suffered from carpal tunnel syndrome or dry, aching eyes from reading computer monitors too long knows there's room for improvement on the interface front.
To delve deeply into the biological inroads researchers are making into
each layer of the computing "stack" would fill textbooks. But to
provide an overview of advances in each layer, we'll follow the example
of analyst Mark Bunger, who co-authored a report last year for
Forrester Research called "Biochemical Computing."
First, what could replace the semiconductor? Several labs are working on the inherent computational power of our natural world. The basic building blocks of life--DNA, enzymes, proteins--process instructions to carry out incredibly complex biological tasks. With our nascent ability to manipulate these molecular structures, could we effectively exploit them to carry out these operations ourselves?
"Like the carefully orchestrated molecular processes that occur within living cells, biomolecular computation can in principle occur autonomously, without the need for any external intervention during the computation," writes Erik Winfree, a professor at the California Institute of Technology in Pasadena, Calif. "Being able to design and understand such systems is our ultimate goal."
In addition to Winfree, work by Drew Endy at the Massachusetts Institute of Technology and others has led to an open-source biotech project called BioBricks. The idea: to build a library of biological components that can be used to create synthetic organisms.
For-profit companies are starting to tap into this idea, too. Craig Venter, the scientist who raced the U.S. government to crack the human genome, has a new company that aims to re-create basic genetic components from bacteria and other sources. It's akin to the way software programmers have access to sophisticated libraries of code and tools when they build applications for a specific operating system.
Memory and storage
As recent headlines about Google and the National Security Agency
underscore, the need to store and sort data for all kinds of purposes
is growing at a 40 percent annual compound rate, according to
Forrester. As cameras become ever more ubiquitous--built into phones,
monitoring street corners or orbiting the globe--a flood of still and
video images will join the data mix.
At some point, the magnetic storage media of disk and tape will be tapped out. Some of the most far-out bioinformatic research is taking place in the field of DNA storage. DNA, of course, is the ultimate storage device. Each cell in your body has a complete copy, which stores 3 billion base pairs.
Instead of strings of zeroes and ones, DNA stores information in strands of adenine, cytosine, thymine and guanine. That's 6GB of storage per cell. And people have a hundred trillion cells in their body, which makes living things the world's most redundant storage devices.
DNA is also inert, so unlike a hard drive, bits of it can stick around for years. Just ask a forensic scientist investigating a long-cold crime scene.
Storing our home videos in DNA, however, will take quite a bit of genetic engineering, so don't hold your breath. But at least two laboratories are working on the problem: the biocomputation project at the U.S. Defense Advanced Research Projects Agency, or DARPA, the same folks who first cooked up the Internet; and the Department of Energy's Pacific Northwest National Laboratory.
Robo-grunts
Today the frontier of the brain-computer
interface is being pushed as a remedy for paralysis, but the military
also is interested in the technology for use in able-bodied soldiers
who will be able to control machines remotely.
The Air Force, for example, has long been interested in what it calls "alternative control technology" to allow its pilots to fly planes hands-free. DARPA is running or funding several projects, including work at Duke's Nicolelis Lab similar to the Cyberkinetics' BrainGate, on that theme, and to develop exoskeletons to enhance battlefield performance.
Whether drastic procedures such as invasive brain implants ever reach beyond the military into the mass market is anyone's guess. But don't underestimate the determination of otherwise healthy people to augment their bodies in all manner of once-unbelievable ways. Indeed, with the ubiquity of personal devices on the streets these days, it's surprising no one's tried to have his cell phone or iPod directly implanted under the skin. That would do away once and for all with fumbling about in your bag or the fear of leaving those devices behind.
Implants or not, the way we interact with computers is in dire need of a rethink, as the digital elite might say. Our keyboards and mice make our hands hurt, our monitors give us headaches and double vision, our desk chairs reinforce our bad posture. On the whole, the organic constituents of our bodies and the inert materials of our computers continue to remain more adversarial than complementary. It's too soon to say when this will change, but we can be sure that change it will.
