Mind controlled

It seems as though Avatar has everyone thinking about the future of mind-controlled devices...a future that may not be so far away. Mind-controlled devices can be extremely helpful to people like Pierpaolo Petruzziello, who had his arm amputated. Researchers at the University of Rome connected a prosthetic hand to his nervous system by electrodes controlled by brain impulses that move his "muscles" to precisely control his hand and fingers.


We have all at one point in our lives thought about conveying secret messages by thought. The U.S. military is funding research at University of California, Irvine, University of Maryland, and Carnegie Mellon University in hopes that soldiers will one day be able to communicate strictly telepathically without interruption or interception of messages. Research began in 2008, and since then, scientists have determined the different thought processes needed to communicate short messages. They have also began to pinpoint where in the brain different thoughts occur so it will be easier to decipher the messages. Turns out that it is relatively simple to send short messages, but researchers are still working on sending lengthier instructions such as those needed in combat conditions (or needed at home to play Modern Warfare 2).

Most of these mind-controlled devices work on electroencephalograms, or EEGs, which measure the brain's electrical activity. In order to develop these waves you need a lot of practice to help strengthen your mind's control. One way to practice is via Mindflex, a game where you use your concentration to to move a ball through different obstacles. In each one of these experiments you must wear a bulky EEG helmet, but Emotiv is working on slimming them down while preserving numerous measuring points for brain activity.

This technology has the potential to create an entirely new form of communication as common as email. But you won't catch me walking around in one of those EEG headsets until someone turns it into a Gossip Girl headband.
