World's first cellphone 'telepathic' chat
Looking something like out of a future robot cops technology tool kit and been described as a "Nerve-tapping neckband used in 'telepathic' chat", the World's first cellphone telepathic call has taken place (12th March 2008). This new technology basically takes the neurological signals from the brain translates them into a transmission signal which is then sent and decoded through a processor into either, speech, communicate to a computer or communicate to move a wheel chair are just some of the possibilities, and all from a band around the neck and the receiver at the other end.
