On-Body Circuits Create New Sense Organ

destinyland writes "In 'My New Sense Organ,' a science writer tests 'a new sense' — the ability to always know true north — by strapping a circuit board to her ankle. It's connected to an electronic compass and an ankle band with eight skin buzzers. The result? 'I had wrong assumptions I didn't know about ... I returned home to Washington DC to find that, far worse than my old haunt San Francisco, my mental map of DC swapped north for west. I started getting more lost than ever as the two spatial concepts of DC did battle in my head.' The device also detects 'the specific places where infrastructure interferes with the earth's magnetic fields.'

  2. What qualifies for new sensory organ? by Bicx · · Score: 4, Insightful

    Is this really a new sensory organ if it just relies on buzzers rather than direct neural connections? Maybe I've just been spoiled by all the awesome research done in computer-brain interfaces.

      The body is an amazing thing. The brain, too. I was recently reading about a camera device that sends signal data to a 'lollipop' that is placed on the tongue of blind people. In short time, the people's brains began to interpret the signals (which are not the same as optical signals at all) as to what it truly was --- and the patients began to see. http://hardware.slashdot.org/article.pl?sid=09/08/22/2035256

      It really amazes me at the ability of the brain to start with some from of stimulus (beit natural or induced) and decipher its relevance.

      The difference in what qualifies 'sensory organ' may well be semantics; or maybe we need new definitions to describe these novel apparatus.

      In contrast, neurons are not in direct connection, either; neurotransmitters span a space between them called the synaptic cleft. Those neurotransmitters are chemical stimuli; these 'buzzers' are electronic stimuli. There are some differences and none are very clearly understood, but as far as I know we might accomplish the same by 'buzzing' with small and rapid doses of neurotransmitters instead of buzzing.

    I've heard of people implanting tiny rare earth magnets in their fingers so they can sense current flowing through wires and magnetic fields. I would like to try it when I can be certain they won't break when they're under my skin... :P

    the ability to always know true north ... electronic compass

    I've been to Northern Canada. A compass points to MAGNETIC North. True North is at the North pole, the point on which the earth spins. At true north, the sun never sets, and sometimes never rises for days on end. In summer, it has the longest days in the world. In winter, the longest nights. Magnetic north is not the same place at all ...

    Magnetic North has some interesting properties too. Amongst others, the Magnetic south and north poles move around, periodically flip, and do not pass through the center of the earth.

      The only person to ever mention "true" north is the Slashdot poster. TFA never describes true north, and actually specifically states that they are using magnetic north. I am not entirely sure *why* they went out of their way to add the "true" and make the description *untrue*, but thought it worth giving credit to the actual science writer for understanding the difference...

    Maybe I'm an exception, but I don't think that's true at all. I navigate entirely by landmarks. I don't even know the names of half the streets I travel on regularly. Furthermore, my mental map of the city is framed by our light rail system, major bus lines, and bike throughfares, not by the major roads carrying automobile traffic.

  8. Don't need electronics for that by Haxamanish · · Score: 4, Interesting

    When I was a teen, I always consciously kept track where the North was. Every time I made a turn, I would adjust my imaginary compass - yeah I was some kind of freak. I would also make note of the orientation of some landmarks in every city. After a while, it became an automatism, now (over 20 yrs later) I often amaze people by pointing where the North is with very good accuracy without using a compass. It always works, but if I have been a passenger in a car (or other transport) it takes about half an hour after arriving before I know where the North is. Extra bonus: if the sun is visible, I can read the time of day from its position. I guess everybody can train it with a little bit of effort.

    1) Find a quote from the article, and claim you've always known it, and what is more everybody already knows it.
    2) Make AWESOME generalisations about "how, like, men and women are different, yeah?"
