Nerve-tapping Neckband Allows 'Telepathic' Chat 205

Posted by samzenpus from the mouth-of-cyber-sauron dept.
ZonkerWilliam writes "Newscientist has an interesting article on tapping the nerve impulses going from the brain to the vocal chords, allowing for 'Voiceless' phone calls. "With careful training a person can send nerve signals to their vocal cords without making a sound. These signals are picked up by the neckband and relayed wirelessly to a computer that converts them into words spoken by a computerized voice." It's not quite telepathy, but it's pretty close."

    Putting aside the "magic" aspect of telepathy that most SciFi authors seem to strive for, I have often considered how telepathy might look if it were a feature of a real species of creature. What I came up with is surprisingly realistic, though it lacks the charm of SciFi style telepathy.

    The way I see it, telepathy is basically wireless communications. A species that "spoke" telepathically to one another in close proximity could use radio waves to communicate in an omnidirectional fashion. For high enough wavelengths, a nerve center acting as an antenna could be exposed from nearly any location on the body. (Possibly metallic in nature?) By modulating the frequency range used to "speak", a creature could become louder or quieter, effectively maintaining the type of privacy we humans enjoy with a whisper rather than a shout.

    Of course, the disadvantage becomes immediately clear. There's no mind-reading involved. No cool body-takeovers, no telekinesis developing, nothing but a simple method of communication that is alien to us, yet accomplishes approximately the same task as human speech.

    It's fun to think that "telepathy is the next stage of human evolution", but there are no obvious physics to support the SciFi interpretation of telepathy. (Especially when you get into telekinesis, which requires WAY more energy than the human body can produce!) What physics does allow us is slightly more boring, but none the less an interesting concept to explore. :-)

A faint glitter in the display screens meant the machine was already tracking her eyes, noting by curvature of lens and angle of pupil the exact spot on which she focused at any moment.

    She didn't have to speak aloud, only intend to. The subvocal read nerve signals, letting her enter words by just beginning to will them. It was much faster than any normal speech input device... and more cantankerous as well. Jen adjusted the sensitivity level so it wouldn't pick up each tiny tremor - a growing problem as her once athletic body turned wiry and inexact with age.

    Jaheezus criminy, must people make /. look so 14 year old golly gee whiz?

    It's absolutely nothing like telepathy. The band is picking up electrical signals in the muscles (called EMG: electromyography) controlling the vocal cords . They can react to reading silently, particularly if you read something "out loud to yourself". If you imagine your own voice while reading something or even imagine speaking, this will happen. It's called subvocalization, and the muscle movements are similar to, but not the same as, speech. That's why the device can differentiate between spoken and "silent" speech. This has been known for decades. Someone has managed to build something that decodes the signals into something like the original words being read or imagined.

    There is no transmission of anything, much less thoughts. Although a novel approach, this is simply another human-machine interface. And one that I'll wager will require fairly extensive training for each individual using it, including training it to read them in different physiological states.
