There are tons of things I had never considered about how difficult it is to fool your brain into thinking it's touching something it's not. I think the most important technical issue to overcome is timing. Much like how your brain can understand hearing someone's voice AFTER seeing their lips move, but not the opposite... the lag time of the sense of touch is an important thing for your brain. Another thing I hand't considered is the "rise time" that has to do with internal stresses in your fingers. If you conceptualize your fingers as water balloons around bones, you can understand how the internal pressure of your fingers rise the harder you press something. This type of information coupled with the "Sensory Homunculus" make for some incredibly fulfilling thought experiments.
The temperature question is something I'm particularly interested in. Using a colder fluid to model a room temperature fluid because of the heat transfer equation is a fascinating area of scientific problem solving. If you think it through, everything about this boils down to differential equations. How much heat is leaking out of the hand, and at what rate, through what contact area?

[@RealEngineering]

Talking to engineers under NDAs is one of the most frustrating and entertaining things in the world.

[@SchMasHed]

Its like jousting in the mind and every blow is a word and the winner is the one that bleeds the least.

[@mmmcake44]

All my channels follow each-other! Guess we're all nerds. Anyways, isn't there a kinda workaround to that? Can't the company issue a small sum of money to you (even 1$), and have you sign a NDA too? Obviously it wouldn't make it to the video, but on a personal level it could open the conversation up. Would still require a decent amount of company trust though, because if you violate it, even if they take you to court, it's already too late for their secrets.

[@theolodger]

I'm excited about Ready Player One so I decided to do a deep dive into the science of virtual reality. This is the second part of the series. I haven't revealed what the next video is about... but it's super interesting and probably a bit unexpected. There are tons of things I had never considered about how difficult it is to fool your brain into thinking it's touching something it's not. I think the most important technical issue to overcome is timing. Much like how your brain can understand hearing someone's voice AFTER seeing their lips move, but not the opposite... the lag time of the sense of touch is an important thing for your brain.

[@Busy_Paws]

The Sensory Homunculus here is *clearly* a Censored Homunculus.

[@kieransaul2711]

No, he's actually an emasculated Sensory Homunculus. Keep your voice down though, because he's very sensitive about it.

[@MiniDemonic]

Your genitals have far far less "resolution" in sensitivity compared to your lips, tongue and hands. The sensory humunculus doesn't depict how pleasurable the sensation of touch is, it depicts how accurate the sensation of touch is.

[@MiniDemonic]

Well, that just proves how dumb you are.

[@kieransaul2711]

Hey now, don't be mean. It's perfectly natural to assume that one of the most sensitive parts of your body would have the most nerve endings unless you were informed otherwise. It certainly hurts more than any other part of your body if you get hit there. EDIT: Except for your eyes, of course.

[@MiniDemonic]

Except that your genitals aren't the most sensitive parts of your body. Pain is sensed by nociceptors while touch and vibrations are sensed by mechanoreceptors. So you can't really compare the two feelings as they aren't sensed by the same receptors.

[@SWRaptor1]

I bet this would have amazing medical applications. Like remote surgical procedures where the doctor can literally feel the organs. Not just like VR or AR, but remote presence. So cool! Thank you for this amazing video!

[@saturn724]

Honestly I think it might take 50+ years for such tech to be available AND reliable for medical use, you're talking about remotely controlling a robot hand that's as precise as the human hand

[@SWRaptor1]

Not long ago we all would've said this haptic tech was years and years off. Not that long ago we said AI was only in sci-fi movies for the foreseeable future. Not that long ago we watched TV and used the internet for emails and chat rooms saying it wouldn't amount to much for decades. Yet here we are. You have to start somewhere with an idea. It doesn't just pop out as a fully developed product. In any case, thank you for the responses.

[@ColePanike]

Awesome response to these comments SW Raptor. The future happens as fast as we make it happen.

[@Kaalyn_HOW]

Def not 20-50 years. Surgeons already learn on many machines and simulations. Haptic simulators aren't THAT far off. Nothing will compare to a real body, but no one person's body is the same anyway -- so it doesn't need to be exact. It's all about practice and building up to the real thing anyway, not being 100% the same. I'd say we're closer to 5 years, though SOME of this tech is already employed in teaching facilities. Edit: With only 15 or so, tops, for more live medical application. We already use tech on patients where robots are an extension of the surgeon's hands, directed by the surgeon. It's just not reliant on haptic feedback.

[@tanketom]

We've got haptic virtual reality for dentists already. Not as large a task as "all of the body", but it's quite cool.

[@s.m.mustafaakailvi2915]

SmarterEveryDay I thought you were putting in your own Easter egg. Destins Almanac.

[@kostis_alexas]

+Chris Renfro I though this as well for a minute but it doesn't seem like it, perhaps easter eggs is a good idea for future videos though.

[@SilentGloves]

I'm sure you already know this, but the sensation of "hot" is not actually it's own sensation, it's warm + cold sensations happening simultaneously. You can simulate "hot" by setting your faucet to a light stream of slightly warm water, and having a cup of ice water. Place your finger under the warm stream from the sink, and then pour the cold water right next to the warm water. Right near the interface between the two, you will perceive "hot." If done just right, you'll instinctively yank your hand away and feel like you've burnt your finger for about 10 minutes. Great fun at parties. I'm betting these guys must've dealt with that in some way, because it would be extremely easy to cause actual discomfort with high enough resolution cold and warm water cells in proximity. I'd even go so far as to say that they probably have a proprietary "faux burning" simulation that they've used to trick coworkers. If I worked there, I would've definitely done that. :D

[@MiniDemonic]

Your thermoreceptors senses the absolute and relative change in temperature, that's why it feels burning when you go from really cold to slightly warm because the relative change in temperarute is big. If you want to be technical then "cold" doesn't really exist. Heat is the movement of atoms, the more atoms move the hotter something is.

[@sylvestrehucher8621]

I'm looking for some more information about the way thermoreceptors are working, like how the sensors under our skin can perceive the excitement of atoms. I'd be glad if you can help me.

[@MiniDemonic]

You have two kinds of termoreceptors, one that senses warmth and one that senses cold. So SilentGloves is wrong in stating that "the sensation of hot is not it's own sensation". There is technically nothing that's cold, it's only a lack of heat. Heat is generated when atoms vibrate or bump into eachother, you can't generate cold you can only take away heat. You can't take away all heat though, as far as we know reaching 0 Kelvin (absolute zero) is impossible. It is possible to go lower than 0 Kelvin though. It seems weird but it really isn't when you think about it. At 0 Kelvin atoms wouldn't be moving at all and be at a 100% stand still, but if you go into negative Kelvin then they start moving again but in the opposite direction. To explain how termoreceptors work you need to go into advanced biology which is kinda confusing. The simple way to think of it is: Your thermoreceptors are just a part of your sensory neurons, they send signals to your brain via electric discharge (like all nerves and neurons do). The warm receptors discharge faster when they are warm and slower when they are cold while the cold receptors discharge faster when they are cold and slower when they are warm, they can do that because they are made from different fibers and have different conductivity. Some cold receptors discharge at high temperatures though, above 45c, and the reason why is unknown. Now, don't quote me on this explanation as it's a vast oversimplification by some random dude in KZbin comments. If you want to learn more I would suggest getting a book about the subject, I can't really recommend one unfortunately but a quick Google search brought me to "Thermal Sensations and Thermoreceptors in Man" by Herbert Hensel which seems to be good but I haven't read it.

[@SilentGloves]

Yes, yes. My point was that when the "cold receptors discharge at high temperatures, above 45c," humans perceive the combined firing of warm and cold receptors as "very hot" and the reflex arc neural pathway responds without giving the brain any chance to make a decision. The brain is too slow. So, you accidentally grab a plate that's say, 180 degrees F, both receptors fire like mad, and your spinal cord decides for you that this is not ideal. Your hand automatically retracts and you jump around like an idiot for a while. You can fake this sensation by triggering both warmth receptors and "lack of warmth" receptors in close proximity with warm and cold water.

[@moos5221]

Man, I'm not a geek, but I always feel like I should be one when I'm watching your videos. These gloves are just awesome, I want one - no - two of them asap! You have such a great way of explaining complicated stuff so that I can still mostly understand what you are talking about. Thank you!

[@FLUXXEUS]

We all know where haptic gloves are going 😂 but it's still amazing technology 👌

[@GrainOfRice]

I've been waiting for this since the podcast

[@santoshp7887]

Which podcast

[@davemcmahon7863]

This is incredible! Amazing technology, blowing my mind with what we can do. Such respect for these men

[@PapawDude]

I feel so....dumb? for lack of a better word, but man, your channel is SO inspiring. Thank you! Thank you for doing what you do in trying to educate the masses.

[@LlwydJohnson]

Am I the only person who's disappointed by the large omission from the sensory homunculus?

[@Kris_A]

The Great Homunculus was a bad guy in Mad Max 2.

[@Rhids22]

Kris A Or maybe he's an unsullied soldier from GoT.

[@ryanschaff123]

That’s because it wasn’t censored or altered.

[@voidmasterone8373]

Impressive tech, can't wait for the public release :D

[@markloeffler85]

I can't wait for 10 years after the public releases, when it actually affordable.

[@shinren_]

Voidmaster One asians will copy the tech

[@nyasha6991]

This is both fascinating and so complex! Wow. I know pretty much close to nothing in this field and yet.... you were able to explain enough for me to understand to a certain level. Nice work man!

[@xdazamx]

the smirk everytime you get close to what is restricted. Perfect job for him it seems

[@vedant6633]

CAN WE USE SMALL PELTIER HEATERS (TEC) FOR HEATING AND COOLING IN THE GLOVE ?? OR MAYBE SOME THIN FLIM HEATERS..

[@Subtlenimbus]

With Peltier effect, heat is only moved from one side to the other, the same as any heat pump. The heat would still need to be moved into or out of the area using some medium.

[@fritzcoleman4915]

This was an amazing video! One thing this did was strengthen my belief in how amazing our bodies are! The size and scope of what they are trying to recreate our bodies do so efficiently and compact. I really enjoy your content and the fundamental base that you stand on, keep the great content coming.

[@koaasst]

all this stuff seems like its just logically easy to make, with details out the butt you gotta take a lot of real time to finely design it. glad people are working on these things

[@pimpshiza]

Thank you so much for pushing them and asking the cool &/or hot questions. And conversely they are amazing for sharing with you being that your content is so readily available... Uhhh... I'll just say it...... to China.

[@chicoktc]

pimpshiza personally I think he stepped way over the line with his questions since the first video. I did enjoy both videos a lot, but I think these guys were almost bullied to submission, I would assume they let it go because of the size of Destin's audience. I also thought it was little disrespectful that ever since the first video he started immediately asking those questions. You know it's a company, you know they want to protect their product.

[@pimpshiza]

chicoktc I'm sure they approved the video before he went live ... But you totally have a point. Reminds me of the Silicon Valley episode where the guys get "Brain Raped".

[@nikolabl8154]

what's are the temperature limits?

[@gpaine]

You took complex mechanical engineering and made it accessible to an early high school level understanding. Thank you for the excellent interpretation. Videos like this can inspire kids to get into higher learning.

[@chester82gtstang]

This video was pretty much the most informative video I've ever seen on youtube. So much info so quick really awesome!

[@jortand]

I hope you had your own talk with them afterwards without the camara just so that you could all geak out

[@specialuset8022]

I think I could become smarter everyday with your videos!

[@aherprasad]

Combatressav actually smarter every month.

[@specialuset8022]

Prasad Aher - Why do you say that? I was demonstrating my insincerity or rather a pun as well.

[@Foonage]

Prasad Aher the name smartereveryday is not based on how often he uploads a video. Destin’s videos are usually based on things we come across in life but don’t usually question. What he wants us to do is to be more open in the things happening around us in everyday life, ask why they happen and pursue for answers therefore becoming smarter everyday. Maybe you’re just joking, but i find it disrespectful to someone who has openly said himself that he wouldn’t upload a video unless he has as much information as possible for us to learn about the subject.

[@phi-net2437]

Thank you Destin, I'm writing a research paper on haptic feedback, the failures of the past designs, current innovations, and the future of the industry, your videos have helped a lot for digesting all the research. You are officially a source for my essay.

[@dotChrollo]

I took a long break from your videos, unfortunately, but it's so interesting seeing how much you've changed since I first saw your content. It seems like you've not only gotten legitimately smarter every day, but also more confident in how much you've learned and how you apply it. Keep up the good content, man!

[@TheDantheman12121]

i recently found out about why metal feels colder at room temp and love telling people about it cus it is just a weird thing and it kinda blows peoples mind!

[@issayoussef5444]

Ambrose and why is that if i may ask?

[@JAMtastesgood]

They explain it in the video, but it's due to the thermal conductivity of the material. Suppose you pick up a book in one hand, and a sheet of metal in the other. Even though they're both the same temperature, the metal draws heat away from your hand faster than the book does. Because of this, you perceive the metal to be colder, even though it's not.

[@TheDantheman12121]

JAM why you say this? My comment was me saying i already knew. To the guy saying you found out in 6th grade i am failing to see what point you are getting at? Tbh i probably learnt at school and did not remember!

[@macpr0c]

They teach you about it in middleschool and you start calculating it in high school, either american schools suck or people just don't care about the lectures

[@TheDantheman12121]

Wtf have american schools got to do with anything? But not everyone has the ability to hold every bit of info they ever get told like you!

[@frederickjk3]

"Is that a goal" I don't know why the question, but I also don't know why they couldn't answer. Of course that's the goal lol.

[@hynekboruvka8346]

This is so much more quality content than vast majority we get on VR here!

[@roelvoort]

So awesome, that these guys are willing to ride that grey line. With that giving some nice geeky info. Keep up the good work.

[@JCBZ01]

I'm getting smarter everyday, thank you 😁😁

[@akshatgupta3944]

Thanks Destin. You just gave me a glimpse into the future. Great job HeptX. I am a mechanical engineer and I know how complicated fluid dynamics gets when we induce temperatures into the fluid and ways to stop equalizing the temperature with the hands maybe with continuous fluid flow,in this case every tactor , I can just imagine how complicated it gets. All revolving around on the principles of psychometrics. Hope you all get successful with this. With this thing the virtual world just got real to me. This is the next BIG THING guys.

[@jairorodriguezblanco615]

Hey, what do you think about using Peltier Elements or some form of the peltier effect on the tactors of a haptic glove? With current size of PN junctions, something could be done perhaps. Have sections of hot facing and cold facing elements.

[@antoninjubault1434]

Hey Dustin, that was an AWESOME VIDEO. Thanks ! Keep going !

[@KevinPalivec]

question? couldnt they use peltiers to do the hot and cold simulations? Mind you that I'm not sure how small you can make one and how fast you could switch the hot and cold sides? seems that smaller peltiers might be able to be reversed faster than larger ones?

[@smartereveryday]

Petiers aren't quick enough. It's all about a concept called "thermal mass". You need a difference in temperature to transfer heat... but you need whatever you're transferring the heat TO to have enough heat capacity to be able to maintain that difference in heat. Make sense?

[@FlumenSanctiViti]

Peltiers were my thought too. If they are placed close to the skin and overdriven with high voltage/current, they could be fast enough. Once the target temperature of an element is reached, they can just lower the voltage to maintain the temp. On the other side of peltier elements, they could have some kind of energy storage medium like water or some other liquid, to dump excess heat to or "take" heat from it.

[@KevinPalivec]

Yes! Now that you point it out! Peltiers only move heat. There wouldn't be enough ambient heat to pump to your finger to "feel"! I wasn't thinking!! LOL

[@whuzzzup]

Two micro peltier elements next to each other for one sensory point. One is to create cold by dumping heat into a copper reservoir, the other one has a heaterwire on one site and dumps this heat into your finger. Well I just realized you don't need the second peltier and can just use the heater.

[@drunkramen]

+1 for mention of Beyond 2000... what a great show that was.

[@RScholar]

DrunkRamen I know, I haven't thought about that show since I was a kid too! And now I feel very old...

[@ryanc2696]

That part about thermal conductivity had me shook. I've never thought about it but it makes so much sense!

[@delportonvlee8701]

Hi Destin. Thanks for being so passionate about these topics. I look forward to every episode. Regards from South Africa. Delport

[@davegrox3150]

I was suddenly reminded of one scene in Sword Art Online, where a female character comments on how warm it is to hold the main character’s hand. (Forgot their names) And we are one step closer to achieving that! I think adding science to games is the right way toward immersion and realism.

[@jonboy318ownzatDO]

Dave Grox SAO is what made me so interested in virtual reality. How cool would it be to actually be inside a game
