Swiss scientists have demonstrated how a partially paralyzed person can control a robot using brain signals alone. The team at Switzerland's Federal Institute of Technology in Lausanne says the experiment takes them a step closer to enabling immobile patients to easily interact with their surroundings through a robot 'avatar.'
Tuesday's demonstration involved a partially tetraplegic patient at a hospital in the southern Swiss town of Sion who imagined lifting his fingers to direct a robot at the university 100 kilometers (62 miles) away.
Similar experiments have taken place in the United States and Germany but they either involved able-bodied patients or invasive brain implants, while the Swiss team used only a simple head cap to record the brain signals.

Fucking awesome. I love science.
Nice! A bit late to help someone close to me, but still great :D

Well, kinda not really. I remember finding a paper about using an EEG cap on someone with an amputated limb when I was researching this earlier this year, might be able to get it again. So it really depends on your definition of able-bodied because while there is a technical difference, it's not really much more significant.

But he's a creator, not a killer.
How is that even possible?

Ok, I found [url=http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1053347&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D1053347]this[/url] one from Iran of all places, in 2002. Says it was done on someone with with a severe physical disability but the paper doesn't appear to say what it was exactly so fuck Iranian scientists for writing shitty papers.

Pretty easily actually. Your brain is just a ~12W meat computer and as such, gives off electronic signals. We can collect those signals, run a frequency diagnostic on them to give alpha, beta, gamma waves and that sort of thing, filter out the background noise from blinking and such, then it's just a matter of telling the computer how to interpret it.
I was going to do a project on it this year but it fell through because my supervisor is going to Japan later. EEG BCIs, good stuff.
Surrogates, very very soon. Is there any info on how they did this?
Nevermind, cheers, Devodiere!

Yeah like Devodiere said, and just to add to it. It isn't really all that new. We have been doing similar things with this for a while now.
They had one where you could control a cursor on a screen or something.
You have to train it, you can't just think "Crush tiny person" and your robot arm just instantly knows to grab a small person and start crushing.
It is more of a think "left" and when you do that they can figure out what signals fire and all that jazz and eventually when those signals are transmitted the computer can say, "That was left!"
Next: brain control for games please.

Controlling a browser with your brain. Despite being complex as fuck, P300 is awesome. Shame I couldn't work on it but most studies have super expensive gold-plated electrodes whereas I only had a $50 headset, I probably would've just gotten garbage.

Taking the article I just posted as an example, imagine if while playing a game you could only press about 8 buttons every minute and it had a 1 in 10 chance of pressing the wrong button. That's what EEGs are like now, and it's not going at a good pace.
I fucking love cybernetics.
Oh fuck, next thing we know Stephen Hawkings will control a robot army.

That would be amazing.

would be pretty awesome if they made a robot for stephen hawking

Who doesn't?
Not that this isn't fascinating and impressive, but this is old news! Weird to think it, but we've been reading stories like this for years now. Bioelectric interfacing is evolving pretty rapidly, actually.
Here's another one:

The achievement here is the distance it's being done over though, not much, but it's still awesome.
wow, no deus ex jokes yet?

We need augmented physical bodies now and upload our soul to the vast net
Just stop with all of these dumb references.
