sensory feedback

anonymous asked:

You know something I only just now thought about? Remember how you said that Naruto was a tricky fighter? Well I'm watching a video on amazing fight scenes and the final Sasuke vs Naruto was one of them. I'm watching it and I see Sasuke use Amaterasu to spear several shadow clones in the chest and it hits me. "Holy shit, The reason Naruto is so tricky is at least partly because his shadow clones let him play scenarios out in real time. He can fail multiple times with minimal consequences..."

Yep! And Naruto gets all the sensory feedback, so he’s learning about his enemies with every failed attempt. It’s honestly kind of terrifying, and I wish they’d gone more in-depth about it in the manga, because seriously. Naruto should have been so much more than just a brute force fighter, and he didn’t get that opportunity nearly as much as he should have.

Why or how is it that when phantom limbs come in contact with other objects or people and actually generate that sense of contact, I'm confused

The answer to this depends on what you think phantom/astral limbs are.

Scientific explanation: Phantom limbs occur when someone’s internal body map does not match their physical body. They are, essentially, your brain going “this body part should exist so I’m going to pretend it does”. Because of that, when the space your brain is convinced contains that limb touches something it can result in tactile feedback. This phenomenon has been documented using MRI in both amputees and people with supernumerary phantom limbs.

Spiritual explanation: A person’s body map is determined by the shape of their astral body, so phantom limbs occur when a person’s astral body does not match their physical one. Phantom limbs, then, are body parts that exist on the astral plane but not the physical one. Because of this, they can pass through physical objects but will often give sensory feedback because they are a real part of you.

Stretchy Prosthetic Skin Feels Pressure, Temperature

by Txchnologist staff

Researchers in South Korea and the U.S. have developed what they call a “smart” prosthetic skin embedded with heat, humidity and pressure sensors that can relay sensations to the wearer. 

They say their stretchy silicone-based material can recreate the feelings of temperature and mechanical strain and pressure through electrodes that stimulate the wearer’s nerves. They argue their integrated device represents the next generation of prosthetic skin research by making previously rigid or semi-flexible sensors soft.

“Recent advances in the design of prosthetic limbs integrated with rigid and/or semi-flexible tactile sensors provide sensory reception to enable feedback in response to variable environments,” the team write in the paper reporting their work published today in the journal Nature Communications. "However, there still exists a mechanical mismatch between conventional electronics in wearable prosthetics and soft biological tissues, which impede the utility and performance of prosthetics in amputee populations.“

Vader headcanon - Hands

His right hand has better sensation, because the prosthetic is better integrated; that’s the one he got after Dooku severed his hand as a teenager, and he had more of an opportunity to tinker with it and make adjustments. If he goes too long without having the nerve connections reset, all of his prosthetics just start returning fainter and fainter sensory feedback, which is eventually overcome by a kind of pins-and-needles feeling. 

An interesting detail: for a while it was canon that Vader lost one of his hands to the Emperor. In Timothy Zahn’s Star Wars: Heir to the Empire (1991), Mara Jade tells Luke that Palpatine was so angry over the loss of the Death Star that he nearly killed Vader, in a punishment that cost him his right hand.

hi i stim because of ocd, to calm me down and stop self destructive compulsions, but i've run into a problem with a lot of stims that have repetitive movements become compulsions (which kinda defeats the purpose of using them) so i wants wondering if you had any suggestions for stims that aren't repetitive? sorry for bothering you

Anon, you’re not bothering me at all. This is a tough question, but I am so very glad you asked it. Truly, thank you so very much for this ask. This is absolutely a conversation I think we the community need to have. I know I have my own pain-related issues with repetitive movements, and it’s important that we examine and discuss all the reasons for which repetitive movements might be an issue so that all stimmers are included in the conversation. So I very much appreciate asks like this that broaden my own horizons on problems stimmers might face, even if I can’t solve them.

The truth is, and it’s something I run up against a lot, is that most stim toys inherently involve repetitive movement. Sometimes these movements are broader or can be varied somewhat (think twisting a Tangle and tossing a bean bag) but sometimes there is absolutely no variation in how one can use it (spinners, fidget cubes). Most toys are designed to give sensory awareness without being a distraction, and part of how they do that is in repetitive movement: doing the same movements over and over gives sensory feedback without becoming the primary focus of our actions. This is everything from stroking a plush toy over and over to squeezing a make up sponge!

Please note that I do not have OCD, just some pain-related aversion to repetitive movement, so everything here is offered by someone trying to think outside their own experience. Suggestions made by stimmers with OCD will be more than welcome because you can do a far better job of helping our anon than I can.

So. How do we get that sensory feedback with a minimum of repetition?

My first thought: kinetic sand. Especially if you get yourself a tray and tools with which to play with it - moulds, cookie cutters, pottery tools. This isn’t about replicating sand cutting videos; this is just about playing with the sand, more akin to how children approach it. Because you can do many things with the sand (shaping, dribbling, cutting, moulding) my hope is that you can alternate these things enough that none of them get repetitive. I know that kinetic sand, for this reason, is my absolute go-to stim for when my pain is severe.

Similarly, playdough and dough. The object here isn’t to sit with a ball in your hands and squish it over and over; the object here is to actively play with it. Build houses, animals, shapes. Look up images of things online and see if you can reproduce them. Approach it more like a craft than a stim - that the making is relaxing (I know I find crafting very good for getting out of my own head) and engrossing, but also something you can vary each time.

Since it crossed my mind that you could play with scented doughs, as a way to make these even more stimmy, I also want to highlight scented things in general for stimming. In your own space, or with the permission of those around you, you can burn essential oils in an oil burner, or put a couple of drops of oil on a scarf/clothing/blanket/plush toy. This might help you relax and calm without introducing any repetitive movements at all. I find most oils moderately relaxing, but lavender is very good for this, and can be blended well with many other oils (lavender and sweet orange is a favourite combination of mine). I’m always running a candle burner while at my desk.

You might also turn this into pressure stimming with weighted items, namely weighted blankets and lap pads. There’s nothing much here with which to fidget, but the pressure/weight of the item might calm and relax you. It doesn’t work for everyone, which is why I recommend trying a DIY lap weight first (a pillowcase stuffed with rice) but it does work for many stimmers. These things can all be scented, too, with essential oils or (if you’re not planning to wash the item) dried lavender heads and other dried, aromatic herbs stuffed inside the pad/blanket.

Candles made me think that I used to light a candle at my desk and have it burn while I’m working, just for the sight of the flickering flame. Humans have a long history with fire - our ancestors gathered around the campfire at night to work and tell stories - and I think there’s something in our collective unconscious attracted positively to light and movement in this way. So, light-up stim toys. I’m thinking colour-changing lights or lava lamps (professional or DIY) as they don’t require any repetitive movements at all, but if you can handle shaking a jar a few times, you might like to also consider glitter jars and balls. Glitter batons require a lot of twisting back and forth, so I wouldn’t try these, but a jar might work. I made the DIY Orbeez lamp using a flickering LED candle - the flickering did bother me, but you might really like it!

(This is outside the scope of this blog - we’re about toys, and I don’t pursue non-toy stims because of GIFs, games and videos triggering seizures and sensory overload - but Tumblr is full of visual and auditory stimming videos, GIFs, games and clips. You might find these a better alternative for you than toys if the clicking/scrolling of a mouse isn’t a problem. There’s a directory for stim blogs here, most of them covering visual stims. Please note that I recognise at least one stim-discourser on that list, although their blog is marked as containing discourse, so I’m not sure how safe that directory is for ace and aro stimmers who are tired of having their validity debated in stim spaces.)

If anyone has better suggestions (especially if you’re a stimmer with OCD) please comment away and I will gladly update this post. I’m going to have a think myself, anon, over the next few days, and pay attention to the toys I use and how I use them. So I’m not quite done with this one yet; I want to look at the fidget toys I use and see which ones are least repetitive and how they’re repetitive, and see if I can glean any useful observations from that.

I hope some of this helps you, anon, but thank you, so much, for this ask. I think this is a really important thing to talk about.

@thedreamer001 says,

Personally I really like brush-like items for stimming, such as the Tactile Tiger Brush (by Sensory University) and the silicone sponge (available at cooking stores and on amazon). There a multiple ways to play with them, and you can get a lot of tactile feedback without much movement.

Thank you for your comment, truly, but thank you even more for letting me know that brush exists. Something meant for chewing and brushing! Want!

Melissa was seated on the counter, swinging her legs as she waited for the designated Doctor. Half terrified they were gonna wipe her systems and re-download Melinda’s mind back into this unit as she had been designed for but she knew she couldn’t go against them. Maybe this doctor was only doing simple systems and physical check…

She tried to remain hopeful. eyeing the computer she had been hooked up to, watched as code appeared, no doubt her sensory feedback. Her attention was caught as a woman came into the Lab, straightening up.

Gender Dysphoria Explained

When Italian neurosurgeon Sergio Canavero announced plans to perform the worlds first live head transplant on a human patient, one of the hurdles the medical community was concerned about wasn’t the surgery, but the recovery.

Dr. Hunt Batjer, president elect of the American Association for Neurological Surgeons, is very worried about the operation, stating, “I would not wish this on anyone. I would not allow anyone to do it to me as there are a lot of things worse than death.”

The fear is that once all of the difficult pathways are connected, such as the spinal cord and jugular vein, that the head will experience different chemistry than the body, which will descend the mind into insanity.

Even today, people still ask me if I can describe what gender dysphoria “feels likes”. I imagine it is a lot like what is described above.

As our brain develops separately from our genitalia, we come into awareness knowing the sensory feedback is wrong. We are missing organs that our brain knows should be there. We are running on a fuel that our brain knows is wrong.

As children we do not understand this undefinable dysphoria. We know something is wrong and few will listen. When we finally do come to the awareness of what is happening, we must witness our bodies betray us as we hit puberty and the poison running through our veins further changes us into something we are not.

It really is a wonder we do not go insane.

Dysphoria is very real.

This is gonna be rambly because it’s late, but oh well. Here’s my ideas on omnic mobility and what makes Genji special from a robotics and processing standpoint. 

@littletoughpuff and @logicalfangirl, I’m betting you’d be interested in this.

I’m trying not to get too technical, but lemme know if anyone has questions! I come from a STEM high school and I’m still playing with robots in college, so some of it just slips into my language.

In addition to sewing my sensory resistance band, I sewed these marble mazes.

I had to walk on a busy street to the pharmacy today so I took the constellation maze with me and fiddled with it the whole way there and it helped keep me feeling less overwhelmed.

The mazes are very portable and fold up to fit in my pocket easily. They are made of flannel so they are very soft to the touch. You can manipulate the marble inside to make it move around through the maze and it slides very nicely.

I am going to make them with fabrics that are not primarily for kids because a lot of the marble mazes I have seen are geared towards young children. This is also great for adults but I think having some soft patterned fabrics that are less specifically for children and more typically for adults would be nice to see.

I wonder if anyone would buy these if I sold them on etsy for around $8. I think they could really help people. Anyone have feedback?

FIC: call it what you want

In which Rhys is President, Jack is everything, and that chair gets used as it should. 

(this fic is all about The Chair. cw for explicit sexual content, drug use, and… consensual possession? i suppose? look. it’s porn. it’s just porn.)

This is what Rhys wanted.

He reminds himself as much a lot. He wanted, ever since he was a kid, to run a company, to be somebody important. He spent a decade of his life in the rat-race to get to where he was.

It’s hard to remember that one the days when quarterly reviews are going on, when Rhys has to talk to his department heads about job performance and quarterly quotas, when he gets back to the office (not his, not really Jack’s anymore, just the office) and stands by the window with his forehead against the glass, his arms hanging heavy at his side. He’s exhausted, his brain buzzing with remnants of information from his day, and he shuts his eyes against it all.

Prosthetic Hand Lets Wearer Feel Again

by Charles Q. Choi

After Luke Skywalker gets his hand cut off during a duel with Darth Vader in “Star Wars,” young Skywalker is fitted with an artificial hand that allows him to both grip and feel again. Now scientists are making science fiction real with a new bionic hand that has helped a patient feel the sensation of touch in real-time through his prosthetic.

“The sensory feedback was incredible,” says 36-year-old amputee Dennis Aabo Sørensen from Denmark. “I could feel things that I hadn’t been able to feel in over nine years.”

During lab tests in which he was wearing a blindfold and earplugs, Sørensen detected how firmly he grasped objects. He could also tell the differences in items’ shape and consistency, such as the distinctions between an orange and a baseball.

“When I held an object, I could feel if it was soft or hard, round or square,” Sørensen says.

Ideas for getting hand flapping past body-policers

For the hand-flapping thing, I dunno if these have already been suggested or not but here’s some things that work for me. Most of them take some practice to get the feel right.

  • Rubbing my palms against my pant legs or fingers  - simulates sensory feedback of air flowing against the palm.
  • Tapping my 4 fingers all at once on a horizontal surface - simulates the whippy feeling of the fingers as you change direction. 
  • Patting my thighs as I sit - bit more subtle, still has the whippy feeling and the air rush feeling. 
  • Isometric exercises with my fingers/palms - works the same muscles that may be getting restless and making you want to flap. I twist my hands into different shapes as I do it and let myself feel the strain as I try to hold it and break it at the same time. This one is a bit more obvious, but if you do any kind of physical activity, you can just say that you’re training hand/grip strength, because it does do that.

Disguising the stim, as a previous submitter suggested, works, too. Previous poster suggested wetting your hands and shaking off water. If you help with cooking, this works with other cooking stuff that may get on your hands - flour, etc. 

Another thing I’ve done in the past is make an excuse to get away from people and go somewhere alone for a minute or two, where I can flap in peace.

Computers That Touch On The Verge Of A Revolution

by Joel N. Shurkin, Inside Science

The electronic revolution has engaged the human senses of vision and hearing. Until recently, it has mostly ignored smell, taste, and touch.

But the sense of touch is on the cusp of its own revolution. The technology is called haptics, a broad definition that relates to anything you can feel.

“Haptics is to touch what optics is to sight,” said Will Provancher, an associate professor of mechanical engineering at the University of Utah in Salt Lake City and CEO of a company building haptic devices.

Bionic hand lets wearer feel what they’re holding
The latest bionic hand can do a lot more than just let its wearer hold things: it can actually let them feel. By hooking into nerves in an amputee’s arm, the new prosthetic can let a person tell how hard or soft an object is and even distinguish its basic shape. “The sensory feedback was incredible,” Dennis Sørensen, who wore the hand during its first trial, says in a statement.

anonymous asked:

But what if the only person Oliver can feel is Felicity?

OH, well this is fun.

Do we want to go full on Haven AU here?? When Oliver returns from the island, suddenly the Troubles descend on Starling City and he can’t feel anything anymore. And really, this is a good thing because now he can fight through just about anything, RIGHT? It will be so much easier to fight crime when he can get shot and just keep going. This would have been a really useful thing on the island, etc.

So basically everyone has troubles, and they’re probably all caused by Malcolm Merlyn (he has some kind of trouble generating machine instead of an earthquake machine??? idk idk it could work). Thea probably can’t see the color blue anymore, which is a problem for her because it’s hard to coordinate outfits now. Tommy suddenly has no alcohol tolerance (bummer, man). Laurel has some verbal trouble that happens every second Wednesday of the month which means she can’t argue in court those days. Moira has mind viruses that she has to control because if she doesn’t, Malcolm will (that’s part of how he coerces her into working with him – if she screws up, he’ll force her to unleash the mind viruses on Oliver and Thea). Roy’s trouble is obviously that he can no longer steal purses without being caught. I don’t know what Diggle’s trouble is (open to suggestions, or I can think on it). Felicity is the IT girl version of Audrey in this universe so she is immune to the troubles, although no one knows that yet. Felicity thinks whatever trouble she has coming is something with a delayed onset. After all, these things don’t affect everyone all the time.

ANYWAY, at first Oliver thinks it’s going to be fine, but ultimately this whole troubles thing makes Oliver’s quest to save Starling City a lot more difficult because no one knows what’s going to happen at any given moment. Plus, Oliver is really starting to be bothered by the fact that he can’t feel anyone. He did just get back home, and while he’s trying to keep his distance from his family to keep them safe, he also wishes he could feel it when Thea hugs him.

So imagine his surprise when the awkward IT girl at his family’s company accidentally brushes his hand when she goes to pick up the laptop and… he felt that. He had really planned on alternating between a few people when he needed tech help so as not to arouse suspicions until he knew who he could trust, but this… this requires some immediate follow up. He doesn’t tell anyone about it, but he does think it’s curious that he can feel her and he wants to try to figure out why.

Felicity doesn’t discover what Oliver’s trouble is until the night his mother shoots him and he shows up in the backseat of her car. She probably says something along the lines of she’d offer him some ibuprofen if she had any, at which point he says he’s fine and it doesn’t hurt. Felicity doesn’t understand that until later, when Oliver is passed out. Diggle explains what Oliver actually meant.

Felicity is very concerned about Oliver’s inability to feel pain being a liability for him. If he can be that injured and still feel nothing, he might not know when it’s time to retreat and seek medical attention when he really needs it! PLUS, there are so many everyday things that require sensory feedback and really, it just makes sense if she samples everything before he eats it when they’re together because otherwise he might burn his mouth! Felicity can’t help it. She’s a worrier.

(They keep trying to stop Malcolm Merlyn but since there’s no earthquake machine it’s more complicated and maybe Oliver kills Merlyn but no one can find the source of the troubles. That’s their big issue: the quest to figure out how to make all of this stop. They know Merlyn was the original source. The problem is, of course, he had a backup. “Redundancy!” Merlyn gloats as he dies.)

So when does Felicity finally learn that Oliver can feel her?? Probably not until after Oliver kills the Count. Felicity is still concerned for him when she notices he was shot, as she always is because he could be a lot more injured than he realizes!! So imagine the scene pretty much as it played out - “You were shot!” / “Hey, it’s nothing. The only thing I feel is you…” and that last part just slips out because emotions are running so high.

I don’t really know what else happens. But yeah, eventually there is sex and Oliver is pretty much in sensory overload and it’s all very emotional.

Not sure a Haven AU is what you were going for, Anon, but I hope you enjoyed anyway.

heartgf  asked:

what exactly does it mean about stimming that it stimulates your brain? im trying to find out more about stimming.

So our bodies detect things in our environment as sensory information - anything that we can see, hear, smell, feel or taste is sensory information. But this information alone is meaningless. It has to be sent to the brain in order to be decoded.

The brain takes this all this information and uses it to identify what something is and how we should respond to it. For example, you see a glass of opaque white liquid in front of you. It has very little smell, but the liquid is cold. It tastes slightly sweet and feels slightly thicker and fattier than water. All this information is sent to your brain, brain interprets the information, and probably spits out a response along the lines of “This is milk. You should/shouldn’t drink it.”

Generally, when someone says that something “stimulates the brain” what they are referring to is pretty much the process I’ve describe above. It’s the brain receiving, decoding, and responding to sensory information. You could say that sensory information stimulates a response from the brain.

Usually, sensory stimulation comes from us interacting with things in our environment that are external to us, like the temperature of a cup of coffee, or being jostled by other people in a crowd.

Stimming, however, is a little bit different. Stimming is an abbreviation for self-stimulatory behaviour, so by definition, it’s something an individual does to themselves, in order to receive a specific sort of sensory feedback. Usually, people stim because doing so elicits a specific, and desired response from the brain. 

This might be because the stim is comforting and makes them feel safe, for example, I’ll often stroke my hair as I’m going to sleep, because this is something my mum did when I was little, and I find it soothing. Alternatively, a stim might be protective, that is, it might help an individual block unwanted sensory information from their environment, by providing a more preferable alternative.

In ADHD, there seems to be a fine line between what constitutes fidgeting and what constitutes stimming, but it’s worth noting that the two aren’t mutually exclusive. A playing with a fidget toy might become a stim, if an individual finds that playing with the fidget is soothing or comforting, in addition to aiding concentration. The same goes for bodily-focused repetitive behaviours (BFRBs) and stimming, although, in this case, the stimming may be a BFRB to begin with.

And that’s about all I know about stimming. Hope it helps your quest for knowledge!

I know before you said that Rangers can 'feel' when a Jaeger is damaged, because of how connected they are, but can they 'feel' other stimuli? For example, when Striker lifted Otachi the Hansens were yelling and their facial expressions looked very strained. Was that because they 'felt' the weight... or because yelling is a good way to express yourself.

They get sensory feedback from the Jaeger. It can be painful, but it’s ultimately necessary for control. (As an illustration, just imagine how challenging it would be to get around and interact with your world if your whole body was essentially numb.)
