Tan Le, co-founder and president of Emotiv Systems, gives a live demo of a mind control device that uses a person's thoughts to input computer commands. This technology has been available to severely disabled people in the past because cost was prohibitive, but the technology is soon to be available on the open market. The device uses EEG commonly known as brainwave patterns to control electronic devices. You first train the software to recognize the unique patterns your brain makes, then it is ready to use. An additional use that is not often discussed is that it can be used directly to collect your thought patterns for marketing or spying purposes. Also this device removes the single largest barrier to controlling people's minds with electromagnetic waves by having each individual catalog their own patterns. The one thing protecting people from mass electromagnetic mind control is the fact that each of us has a unique pattern. It may even be possible to feed those signals back into the brain with this device, creating all types of sensory hallucinations.
