Is the virtual reality in sword art online plausible...

Is the virtual reality in sword art online plausible? The nerve gear allows users to move and have five senses in the game, but also blocks every signal from the brain to the body to prevent it from moving irl. I have little knowledge of vr, so I'm curious if something like this is practical.

Stop watching anime.

Yes, but were far off fully figuring out how the body communicates with the brain we know the basics but need to create like an API
And then of course you'd be opening up Pandora's box into rewiring people's brains

Its almost certainly plausible.
Just that we are nowhere near developing it and likely wont be for a long long time (at least as a whole, parts are coming along)

I think first off they will start with intercepting muscle signals as at least that seems relatively closer to something doable. Such as with prosthetic arms that can be hooked to leftover muscles in the shoulder area and can move just by thought. They also have things like transcranial magnetic stimulation where they can test what parts of the motor cortex activate for movements and such (though its not super accurate yet), so if that develops further it could easily be what gets the muscle/movement signals and sends them to a game (though next problem is having your body not move still, as its just reading the signals not stopping them).

As for the five senses
-Sight for at least the first while could be done how VR is now (with eyes still open), if you get good enough screens and lenses and customise all the specs to fit the person (so IPD, changeable lenses for glasses wearers that correct sight so they dont need glasses, perfectly fit to the persons face so nose is comfy etc). Because sight even now with pimax and starVR for example doesnt feel to unrealistic (well kinda).
-Sound is probably easiest with a really good pair of either IEM or over ear headphones that are developed to block out sound, be clear and super comfy.
These above 2 as i've described aren't exactly super advanced (beyond just being better versions of what we have now and are naturally developing anyway). But if you get the body sense immersion done (muscle signals above + plus feeling touch) you would easily forget/ignore these above 2. Though i guess if we get advanced enough tech to have imitated touch and stuff we likely will have better tech for the sight and sound anyway, though who knows.

holy fucking autism.

-taste, ill admit i have no idea about anything to with any research done in simulating this sense so i cant really contribute much discussion here.
-smell, well southpark already did fart and vomit smell so we are getting somewhere, kek. But really its just a lot of bottled smells you can have right now, not sure how far research is into making a base few chemicals that can be mixed in ways to imitate into other smells, but i dont think its really even close to a thing yet as each smell is literally molecules coming off the specific thing you are smelling so im not sure how well faking it can go. as in don't think you can just send a fake signal to the brain to imagine a smell.
-touch. this one is at least being worked on fairly seriously, with haptic gloves and full body suits being worked on, though they are still as far as i know just doing basic stuff and could be ages off a suit that can do hot/cold to a specific area of the body, let alone anything on the face/head or even more so sexual things

then you've got balance/motion sickness, but there is already a good amount of research into Galvanic vestibular stimulation which is just fake signals to the inner ear mechanisms in control of balance/motion sickness. So with how thats actually going decently well i assume by the time any of the other more complex senses and such are able to be faked this tech will be even further along.

part 2/3 (typed more than i thought i would)

Watch better anime.

I think somewhere around 15-20 years from now you will have a very good whole package VR, absolutely not on the level of SAO, but still pretty great nonetheless. By then sight and sound could both be delivered fantastically (even if its "not advanced" methods we currently use just further improved), vestibular stimulation will likely be quite good (as its decent already), i think by here they will have some level of muscle signal interception that can translate to a game. and for touch i think a haptic suit will atleast be able to do pressure very well by now and possibly also heat/cold into relatively localised spots. So none of the areas will be even close to perfect, but with how into VR you can get with tech as it currently is, can you imagine how immersive just basic forms of the above would be?

Also, not sure why i replied so detailed to a dying thread other than boredom and the fact that im very interested in the area, but hopefully someone found my thoughts at least interesting.


part 3/3

I know, i know. im just fucking bored and this area does interest me. Im as much typing it because i felt like just thinking about the area myself as i am for anyone to see this.

Thanks, this was a pretty good breakdown.

Implying season 1 first half plus the movie aren't great (as well as so far of season 3) and that season 2 as a whole isnt at least good. The only actually bad part is season 1 second half.
Overall i'd say thats pretty good, keep in mind i only called the best parts great not even like fantastic or amazing.
Then even if "critically" wise its not fantastic (though like i said i think some is pretty good at least) overall its still entertaining and that is the larger purpose of any media entertainment.

No problem.
Though if you are OP and you actually wanted discussion on this i would recommend next time to not use SAO as the OP image (just something else VR related), maybe use it in your question description as an idea of what sort of VR you want achieved, but dont focus the question on SAO too much. There is a weird amount of hate for it all around the internet so you wont get good discussion if you have it too heavily in your post.

Nerve gear would be cool as hell but a Neuro Linker would be able to be used for productive purposes and still provide that gaymin experience.

yeah neuro linker or even the AR headset from the SAO movie are more likely to kick off in real life as you can make cool games for them while still having normies use them (VR is too closed off and weird for most people).
I think how everyone gets their neuro linker as a kid in accel world is certainly not a thing that will happen anytime in the next 50 years plus (its a bit too weird), but i think how AR took off in the SAO movie is highly plausible.

stop watching shitty anime

GGO Alternative is the only sao worth watching.

The movie was actually pretty good too. Gave a decent idea of what I think could realistically happen with AR in real life in the not too distant future

whats with this meme?
I 100% agree its not some super well made or artistic show like cowboy bebop (or in its own weird way NGE), and its not even close to a favourite for me.
But i'll give it this, SAO was definitely entertaining, more entertaining than a vast majority of anime. It even has less of the harem and waifu bullshit (the biggest complaint people post for some reason) than most animes. So why is there this massive hate boner for it? Is it because of the potential it had at the start and it not living up to said potential? i could understand being disappointed/annoyed at the show a fair bit for that, but just because its not as awesome as it could have been doesn't instantly mean the whole thing is complete shit. I don't get how one could say everything about it is shit then go on liking most of the retarded anime shows that they do like.

*SAO Alicization is the only sao worth watching.

I haven't watched SAO but that sounds extremely fucking dangerous

Bump

It was a good season but they should have expanded more on the first season in Aincrad
Even fillers would have been nice to watch. Even though Asuna has is a Hot ass bitch that I would like to nail hard to the floor, her fucking character sucks ass like a cardboard.

Bump

I would say the movie and the mother's rosario arc were pretty good.

Go back to you fucking cancer

Only isekai matters now.
Male power fantasy is the norm.
Fucking loosers.

Your asshole is the only loose thing here.

When you sleep your body is paralysed to prevent it acting out your dreams. Failure of this causes sleep walking.

fpbp and bnr

Nerolinker matrix style. No, forget it. It could happen in the future but wil be very complex and entails brain surgery and alot of connections to various parts of your brain with side effects from apparatus errors that could kill or permenantly damage your brain.

Currently, with medication or electromagnetic appliances you could selectively block motor power/neural connections of the whole body or at a certain level. Its just basics of anesthesia. Mind you this also has some side effects as our body systems are to a variable degree neurally controlled and this is why you have some doctor watching you during anesthesia and dealing with the side effects.

>they should have expanded more on the first season in Aincrad
Overall i like SAO, but 100% this, it was clearly the most interesting setting they have yet they rushed through for some reason.
They eventually decided to in a kind of remake in the light novels where they are doing the aincrad section in detail, so maybe if they ever need something to turn into anime they can do that.

that is a very good point, if they haven't already im sure scientists will figure out how that happens and be able to induce it on purpose

does anyone have any good links on info about where haptics technology currently is at?
i know some people are making glove type things and i thought i saw something about a suit too, but i dont remember much about them and keen to have a proper look.

Agreed.
Hope you can join in on the next /cyb/ general when it appears.

What a stupid looking picture.
It looks like what some next level edgelord imagines himself to be as he exacts vengeance upon all those chads and stacies who made fun of him for constantly picking his nose and having an ugly haircut and jacking off in class; he walks down the hallway in a black trenchcoat, his shitty pot metal anime swords that he got from budk will soon have their thirst for blood quenched. Yeah, he's totally going to kill like twenty people today, and not get his shit kicked in by one guy with a chair before he even gets a chance to break the swords on a wall trying to spin around like a propeller.

im happy a few people actually liked my post
If i see the thread pop up ill definitely join it

No VR like that will have to be done in a suspended exosuit.

kys shit taste faggot, only original concept is good, ALL actual execution is abysmal generic mary sue shitshow

We have to gas the kikes before that can ever become a reality. They'd fill it up with propaganda, ugliness, and virtual niggers.

stop being retarded, we wont have a 5 senses packages without direct brain/nerve hooking, because it would be supremely expensive and clunky otherwise we already have working prototypes of bionic eyes sending signal straight to brain thank to recent machine learning advancement, so not that far off

Fpbp
Definitely possible. VR might be janky as fuck now, but getting to this level of /cyber/ is almost guaranteed. Main problem would be making this something marketable, affordable, and profitable in the first place if we took Wrecky Cowabunga’s numbers into account.

Bump

This is top notch Jesus

Excellent.
