    The U.S. Army is developing a technology known as synthetic telepathy that would allow someone to create email or voice mail and send it by thought alone. The concept is based on reading electrical activity in the brain using an electroencephalograph, or EEG.

    Vocal cords were overrated anyway. A new Army grant aims to create email or voice mail and send it by thought alone. No need to type an e-mail, dial a phone or even speak a word.

    Known as synthetic telepathy, the technology is based on reading electrical activity in the brain using an electroencephalograph, or EEG. Similar technology is being marketed as a way to control video games by thought.

    "I think that this will eventually become just another way of communicating," said Mike D'Zmura, from the University of California, Irvine and the lead scientist on the project.
    The Army grant to researchers at University of California, Irvine, Carnegie Mellon University and the University of Maryland has two objectives. The first is to compose a message using, as D'Zmura puts it, "that little voice in your head."

    The second part is to send that message to a particular individual or object (like a radio), also just with the power of thought. Once the message reaches the recipient, it could be read as text or as a voice mail.

    While the money may come from the Army and its first use could be for covert operations, D'Zmura thinks that thought-based communication will find more use in the civilian realm.

    "The eventual application I see is for students sitting in the back of the lecture hall not paying attention because they are texting," said D'Zmura. "Instead, students could be back there, just thinking to each other."

    EEG-based gaming devices are large and fairly conspicuous, but D'Zmura thinks that eventually they could be incorporated into a baseball hat or a hood.

    Another use for such a system is for patients with Lou Gehrig's disease, or ALS. As the disease progresses, patients have fully functional brains but slowly lose control over their muscles. Synthetic telepathy could be a way for these patients to communicate.

    This would create a vast improvement in command and control capabilities for multiple small groups operating in a hostile environment. But I think it should be used for exclusive military use. Things are bad enough in our education system as it is. We don't need any more new technologies distracting our kids. Also, it would create a security nightmare. There are enough ways to create a terrorist act without using telepathy. It could be a long time before we could develope a method for defeating this. If it would even be possible. Could there be any benefits to introducing to the civilian sector?

    Commercial EEG headsets already exist that allow wearers to manipulate virtual objects by thought alone, noted Sajda, but thinking "move rock" is easier than, say, "Have everyone meet at Starbucks at 5:30."

    One difficulty in composing specific messages is fundamental — EEGs are not very specific. They can only locate a signal to within about one to two centimeters. That's a large distance in the brain. In the brain's auditory cortex, for example, two centimeters is the difference between low notes and high notes, D'Zmura said.

    Placing electrodes between the skull and the brain would offer more precise readings, but it is expensive and requires invasive surgery.

    To work around this problem, the scientists need to gain a much better understanding of what words and phrases light up what brain sections. To create a detailed map of the brain scientists will also use functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG).

    Each technology has its own strengths and weaknesses. EEGs detect brain activity only on the outer bulges of the brain's folds. MEGs read brain activity on the inner folds but are too large to put on your head. FMRIs detect brain activity more accurately than either but are heavy and expensive.

    Of all three technologies EEG is the one currently cheap enough, light enough and fast enough for a mass market device.

    The map generated by all three technologies will help the computer guess which word of phrase a person means when a part of the brain is lights up on the EEG. The idea is similar to how dictation software like Dragon NaturallySpeaking uses context to help determine which word you said.

    You could say that. At least I would know that they could control me.

    Yeah, because that would be so much less distracting :lol:
