    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?

    I asked HaptX for a blurb to explain their company. This is what they came up with:
    HaptX is a multidisciplinary team of engineers based in San Luis Obispo, CA and Seattle, WA that builds advanced haptic technology. Their first product, HaptX Gloves, brings touch feedback to VR with unprecedented realism, enabling a new category of industrial training simulations. Founded by Jake Rubin and Dr. Bob Crockett in 2012, HaptX won’t stop until you can’t tell what’s real from what’s virtual. Learn more at

      I loved this video. It has a mystery to it. It's as if we're trying to figure this out as well, and not just you, Destin. It really gets your gears going. I wouldn't say "no" to more like this.

      peltier with very small heat capacity material...

    5. Andy Jame

      Can’t wait to see this when it’s much more developed and ready for the general consumer.

    6. Bolecular Evan

      Hot or cold, they could be water proof and just pouring water onto your hand and since you have a head set you would not know

    7. FAlSe

      "I don't think VR will take off." Funny thing about that is that it's wrong.

      SmarterEveryDay what's that remote looking light with the cord running down the wall? It looks so cool

    9. ENDERSTIXgaming

      ok so I have gamer hands. basically my fingers curl due to constant typing and using a mouse. would this affect how the software can visualize my hand?

      You extended tech that Kurweil did years ago for the blind.

      This is so crazy! Before I even knew the subject of this video,,, I searched the Nintendo glove online. I'm not crazy about buying pointless stuff, but as I grow in my adult life, I want the things from my childhood, and am willing to pay to have them in my personal museum! Obviously the Nintendo glove is nothing like what you're wearing here,,, but in a 90's world,,, it's the glove to own. We are pretty much the same age, and I have to believe that you appreciate my endeavor!!!

    13. Shamrith Ponlingam

      maybe they use peltiers for hot and cold. and they are pretty instant

    14. Rohan Dayalwal

      AI and modernization have made huge progression in the past decade in almost every field.... But there's still lot potential in the field of textiles. With the combination of other technologies. I'm sure textiles can come up with amazing products!

    15. Dmitry Belugin

      May be they can use Peltier modules to do thermo stuff in this glove?

    16. S N

      Really appreciate your videos!

    17. DewBren

      I wonder if the heat is a pad. I can’t remember the name of them but they’re talked about on electrobooms page but one side heats up while the other cools and can change with the polarity of electricity

      1. DewBren

        I’m meaning in the future if that’d be able to be implemented into the glove for temp

    18. Kirby Pua

      The amount of technicality that comes into touching something is insane

    19. Marc Sheldon

    24. Jack Pilcher May

      You took away the massive genitals on the sensory homunculus?

    25. Clip

      This is a really cool idea. Missing some things though. There's nothing to stop your hand from going through a virtual table, for example. You would need an entire arm unit for that. Maybe have a unit with both arms, chest and hands. This makes me think a lot about the mechanics of the body.

    40. rishik mishra

      I don't really know much about tactile feedback but just wanted to ask if magnetic repulsion would be better in the tactors instead of using hydraulics ,it would save the space and could be faster

    49. Peter Gambier

      Thanks for this Destin, imagine what a whole suit of those sensors would be like.

    50. Morne Kleingeld

      Hello, I would like to know instead of using air in glove and use all the space in glove, wouldn't it be easier to just use electromagnets and a plate of iron in pads to give the same effect? Using electromagnets instead of air pads it will greatly decrease the size of the glove as well as make more room for move ability in the glove. Also by using electronics instead of air pads the hole thing could be run from your home without the worry of air leaks.

    51. Michael Schmidt

      @18:12 I LOVED BEYOND 2000! That show pretty much inspired the medical science nerd (any science for that matter) that I became. I love working in medicine. I thoroughly enjoy physics and chemistry. Such fascinating stuff on the horizon.

    52. h3lix86

      doesnt matter how secretive they are now. as soon as they release it some company in china will reverse engineer it and sell it for a quarter of the price.

    53. CiPoint

      They probably use water-cooled Peltier elements.

    54. Strapon Divine

      7:18 if the sensory homunculus was actually illustrated correctly then it would have some really giant genitalia.

    55. Svidadtv

      "Nobody cares about electrical engineers." Being a student of mechanical engineering I can totally relate 😂

    56. maddog

      I love how at 7:21 they had to leave out genetailia and made the animated photo "Smooth" down their, because if it was realistic we all know how that animated guy/girl would look... lol

    57. Adam

      It bothers me that you're sponsored by 23andme, do you not have issues with the privacy aspects of it?

    58. Kevin Jo

      Hahaha! So according to the sensory homunculus we do not have a single nerve ending in our reproductive organs or nipples, or did they just leave that out so not to make all the focus about those parts?

    59. veggiet2009

      Thank you for providing the captions because I couldn't quite make out the name "tactors" I thought it was either "tappers" or "tackers" lol

      IDEK why he reminds me of Matt Damon. But wayy smarter.

    61. Lóránt Farkas

      If you people really determined on it i suggest to make it slimmer, because how it is right now, it's next to useless.

    62. H B

      'do you create your own language for the glove' Adam: *looks down in dissapointment at the lack of computational jargon*

      I think, this Technology will only work with Nano - Technology and probably even with a Quantum Computer

    64. Tyren Lippelt

      13:03 the voice crack tho 😂

    65. Robert Sharp

      I love VR, but things like this are exactly what i feel VR truly needs to be "mainstream" ... VR has so much potential for the future.

    66. Fisk MacTaggert

      it sounds like they use techs for the temp control

    67. OC-K1NG

      Destin, do you think they might be using Peltiers for the hot and cold that way they could switch relatively fast.

    68. Yeshwanth Nature lover

      Can you say about smell detector

    69. Nicolai Hansen

      Still not able to replicate the feeling of picking up a ball. or cylinder and squeeze it. so that you would feel the actual object that you are holding. Either way this is freaking amazing.

    70. Deqod Pr4l

      I like how at 7:07 he smiled so big when Dustin said I dont even know what that means

    71. C.I. K.

      This is incredibly amazing. I wish I was intelligent enough to do work like this.

      1. Abdallah A.Raheem

        I believe if you started. Step by step you could build sth like this.

    78. that e36 dude

      Is there actually an up and down in space. What do we have as a reference. Random alert

    79. iplayzzz

      Do you know if they use AI in their software (or plan to) so that they can anticipate user actions and prime some kind of secondary bladder to provide a lower latency to activating the tactor when the user performs the anticipated action?

    80. KingWisp

      As someone who’s wanting to look into this as a career, what kind of education would a job at haptix require?

    81. Phi-Net

      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.

    82. David Rutitsky

      Destin thought he broke something at 4:09

    83. alkoia

      they could use thermoelectric pads and just switch the polarity to produce hot or cold sensation, so they don't have to deal with hydraulics!

    84. Alex Tveit

      Have watched this video probably 4 times over the year since it was released. Just love the content and how the interviews were conducted. Please please continue to do follow-ups and similar videos

      What I like about these kinda videos is how intelligent you are, there's no way a LOT of people could hold a technical conversation with boffins like this but you hold your own, we can see the brain ticking over and then you surprise them with your questions and assumptions on how the hardware is working. You could see that with their facial expressions and looking at each other for approval haha.

      These guys are way to protective. Technology moves so fast this is already old news. I understand they dont want people to copy them but dont have dustin come interview you then because he will ask and you guys go erm can i answer that makes you look dumb.

    96. morning1500

      Hi, Destin. I THINK I have an answer for the thermal interactions... Peltier junctions. If current flows one direction the hot and cold sides will be one way. Reverse the current, and they flip over! Thus, you'd have one side of the junction touching your hand, and the other some kind of heat sink. This is where just a steady flow of water would be sufficient... you don't have the lag of the flow, or lags in changing the temperature, etc... the Peltier junction is against your hand, and can change very quickly, depending on the current flow and direction. By changing the "attack/decay/sustain/release" of the current, they can make the temperature change quickly, slowly, etc, and adjust your perception. NOTE: I have NO CONNECTION AT ALL with the folks at HAPTX, this is just MY THEORY about how this works... based on the limited information given here, and my own GEEK factor. :) Just FYI, I absolutely LOVED this video and the one before it... these are AMAZING and are my favorite of all the "Smarter Every Day" vids. :) God bless!!
