The U.S. military has a growing interest in brain-computer interfaces: sensors that pick up brain signals and electronics that convert them to digital information that can be read by computers... A group of scientists from several universities has created an unobtrusive brain-computer interface strip that could revolutionize the way humans convert their thoughts into a machine-readable format. A narrow strip affixes to the upper neck, performing the data collection of a traditional EEG cap. The signals are then interpreted by software —aided by machine learning— to produce data that could be used to steer vehicles or operate other computers. The...
