The brain-machine interface

For the second time in less than a week I came across an article detailing how technology companies are trying to harness brainpower. Yes, human brainpower, and no, this is not science fiction. Just thinking moves toy train with new technology from Hitachi and Human-Aided Computing: Microsoft researchers are trying to harness untapped brain power were both published in the MIT Technology Review on Friday. Both are fascinating. Sample sentences from the articles: " But subconscious computing is a nascent field." and "A key advantage to Hitachi's technology is that sensors don't have to physically enter the brain. Earlier technologies developed by U.S. companies like Neural Signals Inc. required implanting a chip under the skull." and "It's really fun to move a model train just by thinking."
