Scientists at Intel's research lab in Pittsburgh are working to find ways to read and harness human brain waves so they can be used to operate computers, television sets and cell phones. The brain waves would be harnessed with Intel-developed sensors implanted in people's brains.
To get to that point Pomerleau and his research teammates from Intel, Carnegie Mellon University and the University of Pittsburgh, are currently working on decoding human brain activity.
Pomerleau said the team has used Functional Magnetic Resonance Imaging (FMRI) machines to determine that blood flow changes in specific areas of the brain based on what word or image someone is thinking of. People tend to show the same brain patterns for similar thoughts, he added.
For instance, if two people think of the image of a bear or hear the word bear or even hear a bear growl, a neuroimage would show similar brain activity. Basically, there are standard patterns that show up in the brain for different words or images.
Pomerleau said researchers are close to gaining the ability to build brain sensing technology into a head set that culd be used to manipulate a computer. The next step is development of a tiny, far less cumbersome sensor that could be implanted inside the brain.
Today, Intel's Pomerleau said various research facilities are developing technologies to sense activity from inside the skull.
"If we can get to the point where we can accurately detect specific words, you could mentally type," he added. "You could compose characters or words by thinking about letters flashing on the screen or typing whole words rather than their individual characters."
Pomerleau also noted that the more scientists figure out about the brain, it will help them design better microprocessors. He said, "If we can see how the brain does it, then we could build smarter computers."
