Rock, Paper, Scissors, Robot

Forget about playing checkers or chess with a robot. Yukiyasu Kamitani and other
Researchers at ATR Computational Neuroscience
Labs have developed a system that
does rock paper scissors by reading your mind. How does it work?
You'll need to be inside an MRI scanner. A computer decodes the MRI
output to identify the "perceptual
and subjective contents" of your brain. As you make rock, paper or
scissors hand
gestures, your brain
configuration is used to control a robot
hand that duplicates your movements. Obviously, the real goal here
is to develop non-invasive methods of controlling prosthetic devices. So
far the researchers have achieved 85% accuracy with a 7 second lag time
on the current setup. The good part is that it works on anyone without
surgery or special training. The bad part is that you need a massive MRI
machine.
So to be able to read someone else's mind, you'll need a big MRI
machine on your head and very strong neck muscles? Hey Bob! Nice
Hat! Yeah, it's a little hard to get through doorways ya know! Even
with, all you'll be able to read is "rock", "paper", or "scissors"
with a 7 sec delay! To be practical, a brain scanning device for
prosthetics will need to be a lot smaller, but this is a really cool
proof of concept that such a thing could work! I could see wearing a
cap or hat and an exoskeleton and seeing people once paralyzed walking
about! That would be awesome!
Now, what if they could turn this device around and inject thoughts
into someone's mind! (Tinfoil hats anyone?) You could then read or
write thoughts! What if you could transfer your thoughts to someone
else and speed up debreifing! Hey, wait, are you thinking what I'm
thinking? :-) Total Recall!
Hey People,i only was this story here an hour ago,have since given it
just a bit of thought and i really do beleive this has the potential of
being one of the greatest medical/robotic discoveries ever.Okay others
here have said its a bit difficult everyone wearing an MRI scanner on
there heads at the moment but i reckon the answer to this is an even
bigger/more powerful broadband based mri scanner that gives
out/receives readings miles away through the people that are using it
wearing an internal/external brain signal transmiter,constantly sending
a map of detailed information to the mri base unit and instantly
receiving the info back to their robotic/prosthetic body parts
therefore eliminating the direct contact with the mri unit and possibly
enabling 100s of people to live their lives connected to one expensive
base unit.I know it sounds a way off but if you think aboout it could
virtually mean the end to paralysis/physical disablement and if the
discoveries of artifical internal organs continues like it is at the
moment then overall maybe a cure to every medical illness or disease
apart from the brains itself through the ease of using the artificial
parts.Thanks,this story really is fascinating and important for humans
future.

Ah yes, but in Brainstorm they just wore a hat / lightweight headset,
and in the Matrix they had to stick a spike in their brain through a
special socket...
I suppose the technical concept of the films is similar though.
To be failsafe the hat would have to implanted into the mri controlled
people,whats the point of having all that technology and movement
capability when the second you forget and take your hat off you
collapse and cannot move p.s. i have not seen "Brainstorm",just
considering the rest of the person being a robot and give him a Robocop
helmet.
... in addition to the size and the weight of the MRI scanner, it
costs like 2.5 million USD!!!! Isn't it a little too costly for the
prothesis to work? From my experience, having the electrode implant
into your brain only cost 1/100 of the MRI scanner, and it only takes
3 hours. And guess what, you can be awake throughtout the time of the
operation!!!!
Yes got the make the MRI scanner a lot smaller or with no actual
contact to it but with the possible future useage and amounts of
scanners produced as a result i am sure the prices could come right
down.

You dont need an RMI machine to obtain enough information, with a really
small sensor you could do, as long as your algorithm allows you to
discriminate information appropriately.
