Two Heads Are Better Than One For Brain-Computer Interfaces

FatLittleMonkey writes "My mind to your mind... my thoughts to your thoughts... Researchers at the University of Essex have shown that combining the output from two non-invasive 'brain-computer interfaces,' computer-interpreted EEG signals, led to a much clearer signal of the subjects' intention than the output from a single subject. To test this idea, they had two subjects try to steer a simulated space-ship at a target planet, by thinking of one of eight possible directions. While a single user could achieve 67% accuracy, this jumped to 90% when two minds were combined. Researchers believe the technique also compensates for individual lapses in attention, and thus may have applications in real-world space missions."

Wow

I think they just proved that 0.33*0.33 = 0.10.

Its is not like two pilots in a jet liner would miss something as big as their destination airport.

Not always.

To counteract this Rodolfo Bay decided to fly a flight from Palma to Hamburg with German press on board to get good press for the airline. Unfortunately he landed at the wrong airport in Hamburg."

Yes, it is true, I lived in Hamburg that time. They had big trouble to get the bird into the air again as the runway was way too short.

CC.

If I'm thinking it, you're probably all thinking it too:

yeah the little head teams up with the big head to surf for the best pr0n...

with the addition of another brain it became "crowd intelligence" or "crowd sourced" and is now sufficiently buzzword compliant.

Oh. Yeah. That too.

Meanwhile, in the lab next door...

While a single user could achieve 67% accuracy, this jumped to 90% when two minds were combined.

Meanwhile, a lone monkey with an hour's training, a penchant for bananas, and a joystick achieved 99% accuracy.
