The idea is basically a retake on search engines. Instead of
querying using keywords to search appropriate matches,
the engine would use a couple of eeg pickups to provide
feedback. It would pick a random site and then gauge how
"pleased" the user was. If very displeased, it would choose
site that differed substantially from the previous
one. It'd be like 21 questions and the wikipedia seven
degrees of freedom game combined.
If the controls turned out to be fairly easy to master, more dimensions could be added to the user control by
multiplying the number of eeg nodes used. All this
decision making would be optimized for the speed that the
user could provide feedback. Perhaps one control could
alter the speed of the queries while the other provided
positive/negative feedback. The idea would be to search
the internet at the speed of thought.

||This might work. Or it might result in a search
engine that always finds pornography, no matter
what you started out looking for.
||(Also, the bandwidth/dimensionality of EEGs just
isn't very high,
not because the number of "nodes" (electrodes?)
is low, but because the signals are so heavily
filtered before they ever reach the scalp. That's
why, if you want noninvasive, then
magnetoencephalography is probably the
way to go. But the idea is attractive as
a cool gadget that doesn't require liquid helium or
an operating suite.)
||If it can mind read how pleased I am that would be a fun
experiment. If I have to decide how good the link is and
then consciously send the signal that is too much decision
making and might put me in an unpleasantly judgmental
frame of mind. The speed of thought can be pretty slow
||On the other hand if you are just judging how good the link
is for this session, for what you want to see this time it's
easier than trying to rate pages on a global scale. But the
early guesses where the system has no idea what you are
looking for are going to be hard to rate except as terrible.

||That's true, perhaps optionally one use it to
supplement a normal keyword search. Linguistically
approximate and then filter through the clutter.
Words can be terribly imprecise, which makes them

||on another note, some guy did this a while ago to
steer a sailboat. he'd just sit on the meditating,
steering the ship. a cool magic trick if you were to
hide the leads. "look ma, no hands!"
||Wait a minute. When I'm researching a beautiful
theory, and I come across page which threatens to
slay that beautiful theory with an ugly fact, then I am
likely to feel displeased - but a search engine which
"protected" me from that unpleasant experience, as
this one probably would, might not be too good for
my standard of theorizing.
