 There we go. I'm intimidating. It's like there's no women on the internet No, it's castrating bitches So Welcome to good vibrations hacking motion sickness on the cheap. I Am Totenkov you will usually see that avatar associated with my screen name So yeah, a little background on myself. I grew up in the IT department of my dad's work every day off from school. I would spend there working on computers and networks and servers Similar as you're gonna work. There you go similar to these but it was a little bit messier and Yeah, so anyways then last year my dad dared me to Hack one of these digital billboards and I spoke actually spoke on this last year at Def Con And it was responsible. It's unofficially responsible for my losing my last job Cuz clear channel doesn't like it So somewhere between computers and billboards. I started having conversations with neon rain and a bend and And we started talking about neuro hacking or using technology to improve processes Involving your brain and body and of course my mind went to The brain that wouldn't die Because I'm like sweet I get to put someone on a table and hook them up to wires and such similar to tiger right next to me So Yeah, just to let you know I have little to no medical background But I do have access to extensive medical resources So the idea behind this talk started when my friend Amanda and I went to go see a really really bad horror movie The camera kept shaking really badly and it wasn't even 15 minutes into the movie before she had to leave the theater because she was getting sick So we started talking about What caused motion sickness and how it can be stopped and we thought it was ridiculous that there was no cure or fix for Motion sickness even though it's been around for Ages Currently there are pills, but I don't think that a pill is a good enough fix There's no universally accepted definition for motion sickness It's usually defined by the signs and symptoms present when you experience it these include nausea vertigo fatigue pale clammy skin increased elevation and hyperventilation Even though this is also associated with men seeing women at DEF CON Oh So So motion sickness first occurred or they assume it first occurred when man tried to improve natural mobility We believe this is when we started using animals such as horses and camels or Using rafts and boats the first recorded incident of motion sickness occurred in ancient Greece It happened on the water and they coined the term nausea Nause being Relive of or related to water and the suffix ea meaning illness So illness on the water makes sense Um So now some time for some statistics yay math 90% of the world's population suffer from motion sickness at least once in their lives 300 million people in the US roughly experience it 9 to 75 million of those have a debilitating response meaning They're immobilized by the signs and symptoms of motion sickness and two million of these people have to visit a doctor to be prescribed something Some people feel the effects of motion sickness worse than others There's been a recent study that shows a genetic predisposition to motion sickness Inherited by either your mother or father Some races feel it worse than others. I found that African-Americans and Asians are more likely to suffer from motion sickness than Caucasians others with increased Increased susceptibility to it include pregnant women frequent migraine suffers and people with anxiety disorders There are different types of a motion sickness and Those are characterized by where they occur Which is in an automobile, you know train or a bus on a plane while playing video games or on a boat Now you would think with all of these people suffering from motion sickness scientists and Doctors would spend more time studying What causes it and they would know how to fix it But they don't So a matter of fact there have been several Theories of causation Starting back from ancient Greece and going to today We're first going to discuss the disproven theories Which Come on Include the blood and guts theory they thought that At first they thought that motion sickness was a result of a blood disease and Thinning of your blood from being on the waters or on a camel Upset your stomach and that's why you got motion sickness. Well, they were wrong Respiratory issues they assumed that it had something to do with the lungs or your heart Then after that was rejected it went to a reaction to shock to the central nervous system and or the atomic nervous system What's once that was rejected they thought it was an infection similar to cholera or yellow fever and Then they're like well, maybe the person's just moving too much and they're getting sick So the over-stimulation is the most recent rejected theory and that was in the mid 60s And now they're going for something called foveal slip Which we'll discuss right now Foveal slip is of it relates to fixation disparity Okay, how do I explain this? okay fixation disparity Lee is When your retina and your phobia have moved over time due to Watching TV or reading a book in the dark staring at your computer for too long and your phobia moves actually inside of your eye a few a Few degrees and this leads to a lack of visual active acuity it There's a misalignment in the eye one eye has these a moved phobia more so than the other It can be a horizontal and or vertical and it results in over or under convergence of the eyes at the fixation point The misalignment of the phobia is only a few arc minutes, which is 160th of a degree and it eventually leads to depth perception problems So unfortunately as hackers and IT security folk who sit in front of the computer all day We are more likely to suffer from motion sickness than normal folks Okay, so here's a picture of the eye if you look There's The phobia right there now. This is where it's supposed to be But over time it moves up towards the retina or down towards the blind spot and optic nerve It leaves us it leaves people unable to track motion accurately with their eyes There's a definite correlation between phobia slip and motion sickness a group in Oxford Found out that it occurs during optic kinetic stimulation eye movement basically Increased fixation disparity leads to increased phobia slip, which leads to worse manifestations of motion sickness Another theory that's going on right now Going around right now and has not been disproven is the motor sensory conflict theory What it states basically is that it's a defense mechanism for your utilize by your brain to protect against neurotoxins it occurs when signals from your Signal sent to your brain from your eyes disagree with signals sent to your brain from your inner ear So say if you're watching a movie and your eyes sense movement on the screen But your inner ear says no, I'm sitting down in a chair your brain goes Oh, you're hallucinating time for you to throw up now Or when you're in a car reading a book your inner ear says you're moving and your eyes say no I'm I'm just sitting here reading a book. Oh your eyes are lying. It's time for you to throw up now It's upset because your body cannot sustain homeostasis Here's your semi circular canals that's part of your vestibular system right inside of your ear It consists of the semi circular canals which is responsible for balance and sense of spatial orientation Movement of your head causes fluid to move from the Indolemphatic sac which is There is right here To push against the cupula, which is this thing right here Which has hairs that translates mechanical movement into electrical signals, which is sent to your brain When the eye sense movements Wait, yeah, I already explained that so Now that we're going into current prevention techniques and treatment Prevention methods include sit where motion is felt the least. Don't read keep your head and body still Face forward in a reclining position. Keep eyes on the horizon Keep window open. Don't drink or smoke and eat small low-fat bland and starchy foods Now I don't know about you, but I can't do Most if any of those when I'm about to go on a long trip, especially on the plane from Florida to Vegas So that just doesn't work for me So I have to go to I can either go to the natural remedies which include powder or liquid ginger the use of acupuncture acupressure or mild electrical shock to either the pericardium which is three finger widths below your wrist, which is like right there or The small intestine 17 Just locate which is located just below the earlobes and the indentations behind the jawbone If you guys pat that is a pressure point also, so don't press on it too long. You'll pass out and I'll feel bad So, okay time to discuss drugs Whoo drugs not the fun kind though Dip in hydramine is the active ingredient in sleep aids You can't use it if you're an infant. It's not good for the elderly pregnant or breast feeders or people with glaucoma heart disease constipation or in large prostate So It's and also it makes you sleepy because as It's pretty off is made pretty obvious since it's the main ingredient in sleep aids There's also antihistamines being used It's most effective when taking 30 to 60 minutes before a trip It less it makes you drowsy and less alert and it shouldn't be used by people with emphysema or bronchitis so after finding all this out, I'm like well, that's kind of lame and So part of the neuro hacking thing is that we like to apply Technology into trying to fix things so it's time for me to present DOS goods The the first one I actually don't have with me it's called an aura oscillator it uses a Program made in pure data to produce a signal in the point zero one to ten kilohertz range Which was chosen because that's the range for typical head movements such as shaking your head nodding it up and down It works using the motor sensory theory as a basis Basically, if you are sitting playing a video game and use your eyes since movement and you start feeling motion sickness theoretically you can put this thing against your the bone in your head and it'll stimulate inner ear vibrations which should stop Motion sickness the onset of the symptoms or making them not as severe By the end I don't have it with me today. I don't have the code up yet, but by the end of the day I'll have it. I'll have the code available here Tone cough comm slash strobe dot txt and the next device. I actually have on tiger They're called strobe scopic glasses their LEDs are mounted just outside the wearer's peripheral vision lights flash at 20 Hertz with eight millisecond Dwell time it prevents your eyes from going into foveal slip and It could theoretically cause epileptic seizures, but it shouldn't so since since this is def con my Device has decided that it doesn't want to work So she's she's modeling it for me anyways Okay, so Yeah, tiger. Can you stand for me? All right, so she's wearing that basically what we have here at the material list Okay, come on get rid of the seizure warning Materialist, okay, so there's this cheap sunglasses found it for a dollar at the dollar store The hat which I found at the bottom of the closet. I think it was my little sisters or something We have a lily pad Arduino right here and then we bought the e-sowing kit now The LEDs are mounted right here and theoretically you won't have the crocodile wires right there so So they flash right they flash right outside your peripheral vision so you only see the flash, but you don't see the actual LED So that's supposed because I from what I've read. Are you okay? Okay from what I've read Thank you tiger From what I read if it was within your peripheral vision then you are more likely to suffer from an epileptic seizure While it's flashing so don't do that By the end of the day, okay, that's all I have by the end of the day you should have I should have all the stuff up on totankoff.com and You can follow me on Twitter as at Totankoff and yes, I misspelled it on purpose. I know That's it
