Two Heads Are Better Than One For Brain-Computer Interfaces 57 57

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."
