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.

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] ... even better |
|
| |
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. |
|
| |
//Yes, but realistic compared to what?// Well, to reality, for example. |
|
| |
//But the magnetic force only affects the ferrofluid, which

|
| |
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. |
|
| |
//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. |
|
| |
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. |
|
| |
//bits of iron [or] woven steel// Bits of iron is better,
maybe:
think about
the eddy currents. |
|
| |
//bits of iron [or] woven steel//
Also I was thinking about comfort ... if it's a really
fine mesh .. maybe |
|
| |
Isn't that some kind of pyramid scheme? |
|
| |
No. You're thinking of pyramid schemes. |
|
| |
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. |
|
| |
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?) |
|
| |
You hold it above your head and let it slide downwards. No zips, no buttons, no laces, just slinky steel. |
|
| |
Isn't blood a sort of ferrofluid? It's rich in iron, after all. |
|
| |
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. |
