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.
