Tech Discoveries
Technology that reads your mind seems like a dream. Or a nightmare. But if Jaguar and NASA get it to work, it could stop you from falling asleep at the wheel by reading brain waves. Scientists are already capable of rudimentary thought-reading.
Sci-fi is full of tales about people controlling machines with their minds, but sci-fi is already here, sorta. For example, earlier this year, during the Cognitive Technology exhibit at San Francisco's Exploratorium science museum, visitors could don electroencephalogram (EEG) headsets that read brainwave patterns to move a robotic arm.
