Here you go
If a monkey can do it in a few days, we humans also can.
His arms were restrained, not defect.

MidnightPride said:


I'm not interested in it if the arm is restrained lol only if the signals aren't sent to the arm it could be different thats why I would need to test :)

Then, just beneath the monkeys’ skulls, the scientists implanted a grid about the size of a large freckle. It sat on the motor cortex, over a patch of cells known to signal arm and hand movements. The grid held 100 tiny electrodes, each connecting to a single neuron, its wires running out of the brain and to a computer.

The computer was programmed to analyze the collective firing of these 100 motor neurons, translate that sum into an electronic command and send it instantaneously to the arm, which was mounted flush with the left shoulder.

The equipment to read and transmit the signal can be cumbersome and in need of continual monitoring and recalibrating. And no one has yet demonstrated a workable wireless system that would eliminate the need for connections through the scalp.

How do you mean?
I just commented about the restrained part because of the
"How well will it work if you have a arm and, can move it without the machine?"
statement.



Seems like it reads the signals, and doesn't intercept them.
That would mean that the real would move at the same time.





this also needs to be solved

MidnightPride said:


As for that statement that is no longer valid however most methods people are using do require either 1. A chip in the brain or 2. direct connection to the actual nerves. I have a general theory of how to get around the chip in the brain problem but, suppressing the signals is another wall that I can't figure out how to overcome just yet.

TK8 said:


Wouldn't that require wires which redirect the electrical signals instead of reading them?
I can't imagine how that would work wireless.

Here's something I read about a while back (but I can't remember where I found it TT_TT)-

Because the brain operates by sending electronic signals to nerves throughout your body, there's some kind of wavelength that they use, and if you had something close by that could read those signals and intercept/interpret them, you could fool the brain into believing that it was moving a different body, etc.

And on another note, there have been studies involving REM sleep and lucid dreaming that would suggest the possibility of taking advantage of a sleep-like state to use VR technology.

On a bit of a side note, with the discovery of the higgs boson (or rather, confirmation) and the subsequent confirmation of the higgs field, there's a good chance physics itself will shortly have its laws rewritten.
My point- there may be some unprecedented new discovery in the field of neuroscience sometime in the near future that will change our understanding of how the brain fundamentally works.

Back more on the topic of the show itself, I like how Kirito and Klein discussed the way to activate skills in SAO, which makes you think about how cooldowns on abilities would work in terms of how your brain interprets it.
Use skill --> skill is on cooldown for 6 seconds --> charge skill, reuse.

It's a pretty interesting mechanic, when you think about it that way.

Don't nerves also produce and (although small) magnetic field?
It could be used to read the values.
And maybe you could also make use of an external produced magnetic field to intercept the signal from the nerves to stop the body from moving.

This is just a wild guess

By placing a highly powerful negative magnetic field over the nerve, the magnetically, positively charged ions will be attracted to the negative magnetic field, thus impeding the flow of the positively charged ions along the nerves to the brain. Of course, some of the positive ions will escape, thereby allowing continued sensation. However, our research reveals that the longer the magnets are in place over the affected site, the more effective the negative magnetic field will become, Thus, the longer the product is used, the more effective it becomes.

Just found this
This is a way to prevent pain from being felt.
You could use something similar to stop the signals that the brain sends

MidnightPride said:
The technology required to make nervegear a reality is in it's infancy and, will most likely stay that way until someone can put real effort with equal funding.

MidnightPride said:

Neural prosthetics are more advanced then the technology for nerve gear. With neural prosthetics you already accomplish nerve gear but, take it to the next level. for nervegear you would only need to grab the signals and, put them onto a computer and, it stops there for neural prosthetics you need to grab the signals send them to a computer then, create hardware for the hand to move on response. where as in nervegears case you would only need the information on the computer and, from there you program the computer to recognize signals and, then plug them into game movements.

MidnightPride said:

At the moment that's the closest to "virtual reality" that I can think we can get to. The senses and, actually "feeling" like your in another world is beyond any knowledge I have. You would have to upload your conciseness to a computer to simulate that and, I have no idea how you would go about doing that lol and, from a moral standpoint I doubt the technology would be allowed do to the high levels of danger. Uploading your conciseness to a computer means leaving your body which would also result in the possibility of you being lost forever nevermind the fact that the only way to actually know if the device is capably of uploading yourself back to the device without human testing

JeffreyZin said:
I'm surprised that Kirito & others were been stuck in the virtual world forever. I wonder if he dies, he'll die for real...

The first episode was good although a little too obvious and unimaginative. Still, the series looks like it has potential. However, I'm already starting to dislike it based on the sheer amount of people who have rated it a 9 or 10. There is no reason that you could rate a show that high after one episode and there is no reason why a show with one episode (and a very average one at that) should be ranked #41 on the top anime list.

I want to like the show, but I feel like this has already made me prejudice against it. I find this happens all the time with new shows and it really gets annoying to see average shows top the list just because they are new. I understand that this show has a very well liked manga so I understand the large following and high expectations, but you can't just automatically rate the anime high just because the manga was good.
