Neuroscientists working with patients suffering from epilepsy have successfully demonstrated how brain waves might be used to type characters on a computer screen.
The researchers presented their findings at the 2009 annual meeting of the American Epilepsy Society.
Jerry Shih, one of the scientists from the Mayo Clinic campus in Jacksonville, Fla. who collaborated on the project, cautioned that the test "constitutes a baby step." Still, it marked another advance toward the day when people suffering from spidal cord injuries can make use of assistive devices controlled by a brain-computer interface. In fact, HPlus Magazine noted that Dr. Gerwin Schalk, who worked with patients using electrocorticography, or ECoG, at the Wadsworth Center, in Albany, NY., has conducted a similar study.
