Device Reads Messages From Surface of the Brain 156
Al writes "Technology Review has a story about a start-up company that has developed a more-accurate and less-invasive way to read a patient's thoughts. Neurolutions, based in St Louis, has developed a small implanted device that translates signals recorded from the surface of the brain into computer commands. The device, which is less invasive than implants and more accurate than scalp electrodes, uses a grid of electrodes placed directly on the surface of the brain to monitor electrical activity. This technology is currently used to find the origin of seizures in patients with uncontrolled epilepsy before surgery. But the company says it could also help paralyzed patients control a computer and perhaps prosthetic limbs using their thoughts. Tests involving more than 20 patients have shown that people can quickly learn to move a cursor on a computer screen using their brain activity."

That said, this is not really a new technology, merely a new application of electrocorticography [wikipedia.org]. Non-invasive it is not, since it involves opening up the skull. It's only "less invasive" compared with poking an electrode deep into the brain.

"More-accurate and less-invasive"? Not so much... (Score:5, Informative)
"More-accurate and less-invasive" is misleading, since the thing that it is "more accurate" than is not the same thing it is "less invasive" than. It is more accurate than the minimally-invasive electrodes-on-the-scalp method, and less-invasive than the more accurate electrodes-implanted-into-the-brain method.
It is, likewise, less accurate than the electrodes-in-the-brain method, and more invasive than the electrodes-on-the-scalp method, so it would be as accurate (and as hyperbolic, in the opposite direction) as TFS to call it a "less-accurate and more-invasive" method as it was to call it a "more-accurate and less-invasive" method (simply switching which existing method it was compared to for accuracy and which it was compared to for invasiveness.)
It would be most accurate (and not at all hyperbolic) to call it a method which is intermediate between two existing methods in terms of both accuracy and invasiveness.

How's that again?

The potential abuses of this sort of device are many.
* Policeman A to Policeman B: "Check this out! Just as fun as a Tazer, but no physical contact required!" (Points government-issued remote control at random passerby and presses button)
* Prosecutor in courtroom to policeman on the witness stand: "And what was it about Mr. Jones which caused you to arrest him?" Policeman: "My government-issued Thought Interceptor Display showed me that he was *thinking* about robbing a bank. And, he also thought about the Pope, the damn, stinking Catholic -- everybody knows what *they* are like!"
* Supervisor at work, viewing a screen while speaking to his/her subordinate: "So, Bill, what do you *really* think of my new policies?"
* NSA/DIA/FBI/TLA agent to terrified detainee: "Mr. Jones, you were the only one who had access to those classified documents whose movements are unaccounted for. The contents of those documents are now in the hands of the . Who have you been talking to?"
Detainee: "Nobody... no-one.... I didn't do anything, I didn't... oh, my God! My neural interface unit must have been scanned!"
Agent: "A likely story. Take him away!"
* Smiling man with a laptop stands near the polls. A voter comes out and is given a media exit interview, and says (twitching), "Yes... Candidate-Johnson-is-the-best-candidate. I-love-candidate-Johnson. Johnson-has-the-welfare-of-the-people-in-mind-at-all-times."
* Doctor to patient who is physically restrained, but continues to writhe madly: "Mr. Smith, I can't find any biological reason for these spasm. Have you installed the latest code patch flash into your Model 43 Neural Interface Unit?"
Yeah, it's mostly tin-foil-hat tallk, but still possible.
Actually, I think the last scenario is the most likely. Who would you trust to write and verify correct code for a device which interfaced directly to your brain?

The origin is Japanese where a double vowel word like konpyuutaa is written as konpyu~ta~ (written in japanese character of course). Written to drag it out you would write one really long tilde but since the advent of computers generally people use a chain of them together. Also of note that you might be interested in from japanese culture. Japanese people often end sentences with a
