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."

2 are better than 1 - ancient wisdom

[davidwr]

Ecclesiastes 4:9-12

9 Two are better than one,
        because they have a good return for their labor:
10 If either of them falls down,
        one can help the other up.
But pity anyone who falls
        and has no one to help them up.
11 Also, if two lie down together, they will keep warm.
        But how can one keep warm alone?
12 Though one may be overpowered,
        two can defend themselves.
A cord of three strands is not quickly broken.

[NIV]
