In order to feel the sensation of positive and negative Gs in a virtual reality environment (ex: flight simulation) Wear a full body suit. The suit has thousands of evenly distributed ferrofluid filled pockets. Sit strapped securely inside a cockpit. There is a strong electro magnet above you, and a strong electro magnet below you. For positive Gs lower magnet gets activated. For negative Gs it's the upper magnet pulling you up. A monitor monitors your vital statistics in real time. If you show signs of distress. Electricity is cut to the magnet.-- ixnaum, Sep 22 2010 The idea that inspired me Sphere_20Virtualization [ixnaum, Sep 22 2010] Ferrofluid will work http://chemistry.ab...ss/liquidmagnet.htm [ixnaum, Sep 22 2010] Diamagnetic levitation http://www.youtube....watch?v=A1vyB-O5i6E [2 fries shy of a happy meal, Sep 26 2010] But the magnetic force only affects the ferrofluid, which merely presses on your skin. To be realistic, you would have to have a ferrofluid blood transfusion to magnetise your entire body.-- pocmloc, Sep 22 2010 [pocmloc] ... even better-- ixnaum, Sep 22 2010 //To be realistic...//
Yes, but realistic compared to what? This is for a computer simulation or game.
If the magnets were actually a toroid (doughnut) sort of magnet, and it moved up and down around your body, you could simulate getting run over by a steam roller, or constricted by a serpent, for just a few examples.-- Boomershine, Sep 22 2010 //Yes, but realistic compared to what?// Well, to reality, for example.-- pocmloc, Sep 22 2010 //But the magnetic force only affects the ferrofluid, which merely presses on your skin.//
That would be adequate. Almost all perception of G comes from a combination of skin pressure and muscle load, both of which would be recreated by such a system (if it worked, which it won't with mercury, obviously). The inner ear (I mean the otolithy bit, not the semicircular canals) tells you about the direction of the G, but not the magnitude.-- MaxwellBuchanan, Sep 22 2010 //Well, to reality, for example.//
I should have said, 'Compared to the reality of what experience?' I guess. Point taken.
Anyway, [Max] pretty well answered my question.-- Boomershine, Sep 22 2010 What's the point of using a liquid-filled suit? You could make it more easily with bits of iron, I think. Better yet, woven steel.-- subatomicsushi, Sep 23 2010 //bits of iron [or] woven steel// Bits of iron is better, maybe: think about the eddy currents.-- mouseposture, Sep 23 2010 //bits of iron [or] woven steel// Also I was thinking about comfort ... if it's a really fine mesh .. maybe-- ixnaum, Sep 23 2010 Chain mail.-- MaxwellBuchanan, Sep 23 2010 //Chain mail.//
Isn't that some kind of pyramid scheme?-- Boomershine, Sep 23 2010 No. You're thinking of pyramid schemes.-- MaxwellBuchanan, Sep 23 2010 You mean, where, if I send the letter to 10 people, I eventually get a free pyramid? Where would I put it? I'd rather have a nice suit of chain mail.-- mouseposture, Sep 24 2010 No, that's chain mail. And you only win the pyramid if you get in at the top.
You have to get into a *suit* of chain mail anyway you can. (Do they have zippers?)-- Boomershine, Sep 24 2010 You hold it above your head and let it slide downwards. No zips, no buttons, no laces, just slinky steel.-- pocmloc, Sep 24 2010 Isn't blood a sort of ferrofluid? It's rich in iron, after all.-- Aq_Bi, Sep 25 2010 Ya, that's right ... I wonder what would happen if you had a electromagnet strong enough. Maybe that's how you could create artificial gravity in 0G environments.-- ixnaum, Sep 26 2010 //Isn't blood a sort of ferrofluid?
