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 haptx.com.

Talking to engineers under NDAs is one of the most frustrating and entertaining things in the world.
Its like jousting in the mind and every blow is a word and the winner is the one that bleeds the least.
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.
Taylor, My channels also follow each other!
why do they have the curtians?! privacy???????
As a developer who used to be under nda all the time, it's frustrating for us too! When people ask you thing and you just are so proud and want to spit it all out but the manager is keeping you on the leash.
It was great hosting Destin in our lab! (Even if he did ask lots of questions to make our engineers squirm...) We'll have news soon about future development, so head to the website and sign up for the newsletter if you want to learn more.
HaptX this comment needs to be pinned. Also, thanks for explaining it enough so that we (viewers) can at least know something about how your products works. Keep up the good work guys
I bet the heating/cooling is done by some kind of peltier thingy :D
You folks are awesome for hosting the information. Wish you all the very best.
HaptX I don’t know if this’ll cross the line, but when there go mainstream, how much will it be? (In USD)
Awesome work, awesome people! I have a lot of respect for you guys and I’ll definitely keep an eye out for your eventual products :)
"nobody cares about electrical engineers. Let's be honest"
*cuts to him talking with an electrical engineer*
I care i dont care what you care about i said care a lot
Lol other engineers just assume EE guys make stuff happen
That was the joke...
"Fu'kin Sparkies" ;)
No one cares about us, they just think what we do is magical. :'(
They left an essential aspect out of the sensory humunculus
Jaque Glassé of course giant genitalia would be above pg lol.
that would sell so quick
You wouldn't be able to see the person
Congrats on making it to *69* likes!

North Korea in a nutshell
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.

Destin. You are awesome man.
Destin this just tells us the same thing that the video does _and it already is in the description_
"Hand't" = Hadn't " Another thing I hand't considered is the "rise time""
Destin I wish all the TH-cam videos are awesome and useful like yours
Is it really fluids, or could it be Peltier Modules?
“No one cares about electrical engineers, let’s be honest.”
One frame later..
“I’m with Jeffery, an electrical engineer”
😂😂😂
Destin: releases video
*next day*
Competitor: We have created haptic gloves!
Where??? Link the competitor your talking about
Apavlakos just a joke about Destin trying to guess the proprietary info that the company is trying to keep secret.
Ahh right-o
Mike Bucceroni yes!
IDK why hes allowed to divulge such confidential info?
The Sensory Homunculus here is *clearly* a Censored Homunculus.
No, he's actually an emasculated Sensory Homunculus. Keep your voice down though, because he's very sensitive about it.
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.
Well, that just proves how dumb you are.
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.
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.
i love tjose reactions though, the 'oh man this guy knows his stuff and is asking questions...' its great
So when are they going to start working on a haptic suit?
So when can we do a full dive?
Oh boy
The creator of this glove, HaptX, used to be called AxonVR, and they made a VR exosuit 2 years go...
Pepa Zdepa I think that most games would remove that aspect and make it just as sensitive as any other part of the body.
RabbitRampage um I'm concerned, maybe that but toned down a bit. I would die instantly!
excellent video with some hiarious editing @12:28
"We don't care about electrical engineers"
*very next scene
"I'm with Jeffrey, an electrical engineer"
• What is your name?
- Ehhh I ehh I don't know if I can say that 😅😅
12:28 "Nobody cares about electrical engineers, let's be honest"...
"I'm with Geoffrey, an electrical engineer"
goddman it geoffrey!
Oh, you watched the video as well?
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!
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
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.
Awesome response to these comments SW Raptor. The future happens as fast as we make it happen.
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.
We've got haptic virtual reality for dentists already. Not as large a task as "all of the body", but it's quite cool.
Man this is so interesting how careful they have to be with the info they let you show. Did they have to see a final cut of this video to approve before you posted? Hope nothing shared ever comes back to haunt them. Thanks for the good content as always Destin!
He's not allowed to answer that.
Hope it isn't like Silicon Valley show where they give up too much info and a competitor comes in.
Destin blurred the stem of the tactor panel.
Eric A i already copied their model, made some little improvements and created a prototype im about to sell to the chinese for 2 mill.
"So what did you eat for breakfast this morning?"
"Uuuuh I can't share that information"
@SmarterEveryDay Amazing job interviewing these engineers..got me so pumped I applied for a summer internship for them AND GOT IT!!! Going to be a great summer haha:)) Thanks Destin!!
I wonder if i can get there as a med student :")
@@moussafiradil1700 are u satisfied with medicine, or do you think it's more interesting to become an egineer?
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
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.
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.
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 TH-cam 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.
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.
SilentGloves this is bullshit
I think the Sensory Homunculus is somewhat modified for modesty :)
which is kinda ironic because the omited parts have A LOT of sensations
Like the bottom of your feet too
What?... oooooOOOOOOHHHHHH! Lmao 😂
However, in this case the direction of dishonesty is probably opposite from normal!
The Censory Homunculus.
at 00:15 - 00:19 am I the only one who noticed that little tiny black dot appearing and disappearing at the bottom left for no reason?
First thing I noticed too.
Welp... that's going to bother my OCD forever now.
+SmarterEveryDay surely I can't help but noticing it
SmarterEveryDay I thought you were putting in your own Easter egg. Destins Almanac.
+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.
this is the greatest stuff ive ever seen
Throughout you could see all of them in almost physical pain of holding back information that they so want to talk about and explain because you can tell this is their baby and they have worked very hard on it...

Awesome another video on haptic gloves. Can't wait for the haptic glove body pillow.
Stephen Playz thanks for your honesty opinion
Your words can't hurt him, his shades are HTC Vive
ziljin You look like Kalkstein from The Witcher 😂
Except its going to go beyond "gaming" and the rare air of scientific imaging and design into the common user realm.
PlayMoGame Kalkstein? Cool
That's a lot of valves. I assume that's why they're using the Vive?
7:18 if the sensory homunculus was actually illustrated correctly then it would have some really giant genitalia.
'do you create your own language for the glove'
Adam: *looks down in dissapointment at the lack of computational jargon*
Who else tried to wipe the smudge at 00:17 And now we all have a smudge mark on our monitors. Smudge is a weird word. Its been a weird morning.
"it's been a weird morning"... and that's when the raptors showed up.
(whoever is reading this add another sentence to the story)
7:22 TH-cam friendly sensory Homunculus, lololol
I thought much the same thing
Destin is so knowledgeable about so many different things
This was some high level nerdy stuff... and I loved every minute of it. Keep up the good work!
Has anyone else not yet tried anything virtual reality related or is it just me? 😭
Science with Katie same
Hi Katie! 👋
Just you
Prestige. You are so wrong or don't understand what gimmick means.
I don’t have the money to purchase anything VR, nor do I have any other outlet for trying it. So I’ve also never experienced anything VR related, but I’d really like to some day. It seems really cool.
Would it slightly remove latency and allow for better control if the tactors used a highly viscous fluid? A fluid would be incompressible as apposed to air.
It's so weird watching you after that Captain Disillusion video... you both are awesome.
Can you explain? I'm out of the loop and confused lol
Thee1Muffin Go watch Captain Disillusion's latest video.
Ready Player One is becoming real, folks. Haptic gloves
Vr masterbation will be a thing😂
This is a sad fact

Jk jk
Wow these guys are taking everything into consideration. The amount of engineering that went into this glove is amazing.
more like smarter every 5-7 days
Getting there.
SmarterEveryWeek
You can watch the videos every day
He should find 6 other people to upload videos with him so we can actually have a video every day
Destin never said that he's going to make you smarter everyday. He's encouraging you to learn something and question things everyday. I recommend to watch his TedTalk!
Congratulations Destin on making possibly the nerdiest video I've ever seen. I love it.
Matt's Mom
nerdiest? you just start entering the crazy cool side of youtube then, welcome xD
At 0:18, a black dot appears on his hand
Question remains: What's the secret of the dot?
tetsi0815 I think a black hole was about to form, but then it collapsed in on itself
the smirk everytime you get close to what is restricted. Perfect job for him it seems
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.
They did not expect Destine to be so Smart...was visible from thier funny faces. They have developed some really cool stuff though.
Their funny faces are because they don't know if they are allowed to answer his questions or comment on his thoughts.
🤔 me watching for 18 minutes pretending I understand.
Am I the only person who's disappointed by the large omission from the sensory homunculus?
The Great Homunculus was a bad guy in Mad Max 2.
Kris A Or maybe he's an unsullied soldier from GoT.
That’s because it wasn’t censored or altered.
@ 3:35 I love how Destin is making eye contact even though it's impossible xD
Take a few guys with southern accents, add some extremely cool technical analysis of a product i didn't even know about before watching this channel, sprinkle it with psychometrics and the result is: I'M IN LOVE!
That sensory humunculus is missing some important parts, just saying ;D
I'd love to see you take a tour at Tesla or SpaceX
Iwijn Voeten he wasn't
Impressive tech, can't wait for the public release :D
I can't wait for 10 years after the public releases, when it actually affordable.
Voidmaster One asians will copy the tech
You and Mark should totally do more stuff together in the future! You can literally see the glint in both of your eyes, so awesome.
Loved this video! Haven't had the chance to actually have a go with any form of virtual reality just yet - but this makes me so excited to see where the technology is headed!
We all know where haptic gloves are going 😂 but it's still amazing technology 👌
I love SmarterEveryDay! Haptic VR gloves are cool too!
The electrical engineer at 13:15 has a similar voice and speech pattern as Roman Atwood.
I love how enthusiastic you are about all this. It makes it a joy to watch. I hope you never lose that sense of wonder.
the most impressive and admirable thing in this video, genuinely, is that a guy who doesn't care for VR, but has an open, information hungry mind, goes into that demo and comes out with a different view than he had before. if only everybody could be so open minded.
"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.
I think I could become smarter everyday with your videos!
Combatressav actually smarter every month.
Prasad Aher - Why do you say that? I was demonstrating my insincerity or rather a pun as well.
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.
what's are the temperature limits?
All your videos are awesome but this was really one of your best. Not only you talk about really interesting topics, but the sense of awe that you transmit is contagious. Thanks for the really great work!
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.
Thank you so much for these videos! Your dedication to education and learning is truly invaluable in our society. The commitment and genuine sincerity you display in your content is outstanding and the fact that you give of your own time in order to educate us and give us knowledge makes this the best channel on TH-cam. Anywho… thanks again :)
Ok, but where are your fingers?
the real question is...
*what is a finger?*
Lurvas777; fyi that music is Moon Men by Jake Chudnow. Just in case you were ever searching for it. :P
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!
Ambrose and why is that if i may ask?
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.
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!
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
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!
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.
I appreciate the humbleness of these engineers. They're well aware that they don't know everything and that their team/other engineers are, as said around the 4 minute mark, more qualified, to talk about certain things. Gotta love someone who doesn't pretend to know everything.
CAN WE USE SMALL PELTIER HEATERS (TEC) FOR HEATING AND COOLING IN THE GLOVE ?? OR MAYBE SOME THIN FLIM HEATERS..
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.
+1 for mention of Beyond 2000... what a great show that was.
DrunkRamen I know, I haven't thought about that show since I was a kid too! And now I feel very old...
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.
Dave Grox SAO is what made me so interested in virtual reality. How cool would it be to actually be inside a game
10:01 - you can _see_ Destin's neurons making new connections. Look at how his eyes aren't even focusing on anything anymore and just dart around. Twenty seconds of brain overdrive right there, just amazing to watch.
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
In a few Years there will hopefully be an full suit! Amazing!😁😁😁
RabbitRampage 😂
I've been waiting for this since the podcast
Which podcast
I hope you had your own talk with them afterwards without the camara just so that you could all geak out
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!
i love at 10:40 when destin asks a question and the guy looks up at his boss in the background who nods and gives the slight thumbs up to say its okay to talk about :D
The problem is when these gloves come to the market they will be 5k minimum.
I will get the off brand version for fraction of the price.
They can sell the gloves at an affordable price by charging only what it costs to manufacture them. They could even charge less. To make up for costs and make a profit, they can over charge software companies for the ability to use their product in their programs. Or, they could just sell the technology and rights to companies to manufacture the product. The more companies the cost is split between, the less each company would need to pay. The less a company pays, the less the consumer needs to pays.
They're going to market it for industrial training applications at first and, I assume, consumer applications later. David, low equipment price would just be half of the solution for attracting people to buy it. The more important part is that there be software people want to use with the product. You won't entice developers to make software for your product if you offload most of the cost to them. If they sold the technology license to other companies to manufacture, the problem of how to make it cost-effective would still be someone's problem.
VR headset, Haptic/temp gloves, Haptic suit, Omnidirectional treadmill, headphones.
Now all we need is smell VR
I am sure they will integrate olfactory sensing technology soon. It's all about decreasing the products we have today and integrating that technology into VR.
Southpark's game had a smell device
It's hard to imagine all of that temperature control stuff fitting into the actual glove with all of it's pneumatics. It's already probably too big to be a commercial product. Electronics tend to scale down very well, but fluids aren't so easy.
I am late for party but pnuematics work with air not fluids
@@iplaygames8090 And temperature can be controlled by a thin metal mesh.
This is easily the best Smarter Every Day that I have ever seen.
There was some good comedic timing in this one. Made the extra length go by fast.
I love the Top Secret element of this video! So funny!
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.
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.
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".
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.
This is your best video ever. Totally loved you breaking the engineering down live in front of the pros! Well done
This is so much more quality content than vast majority we get on VR here!
I started laughing when you went to the electrical engineer xD
I know well that you need an income, but I personally don't like or trust 23andme with my genetic data. Their third-party policy is where it breaks the deal for me. Plus they would be required to give the data over to authorities if required or they can give it out anytime that they want under their 'good faith' section of their policy.
Just Thomas you should watch the video where he visits the 23andme facility.
CONSENT TO THE TRANSFER OF YOUR PERSONAL INFORMATION
2. We will not sell, lease, or rent your individual-level information (i.e., information about a single individual's genotypes, diseases or other traits/characteristics) to any third-party or to a third-party for research purposes without your explicit consent.
6. We will use your genetic information and/or self-reported information and share it with third-parties for scientific research purposes only if you sign the appropriate Consent Document. Note that we will disclose your individual-level information only if we obtain additional explicit consent from you.
----------------------------------
What's wrong with their third-party policy?
4.b.iii : Your Genetic Information and Self-Reported Information may still be used by us and shared with our third-party service providers to provide and improve our Services.
4.e Under certain circumstances your information may be subject to disclosure pursuant to judicial or other government subpoenas, warrants, or orders, or in coordination with regulatory authorities, we may be required to disclose personal data in response to lawful requests by public authorities, including to meet national security or law enforcement requirements. 23andMe will preserve and disclose any and all information to law enforcement agencies or others if required to do so by law or in the good faith belief that such preservation or disclosure is reasonably necessary to: (a) comply with legal or regulatory process (such as a judicial proceeding, court order, or government inquiry) or obligations that 23andMe may owe pursuant to ethical and other professional rules, laws, and regulations;
4.b.iii worries me because of their service companies having separate terms of service and/or the twisting of the word 'improve'.
4.e worries me because of their '23andme will preserve and disclose any and all information... in good faith belief... to comply to obligations that 23andme may owe to ethical views.
Then there is the whole point of a government discriminating against people due to their genetic makeup (ex. internment camps)
Another point is that Google and 23andme have close relationships and 23andme states that they will keep your information in their database . This makes me worry that like Google, 23andme will change their terms of service and start actively selling data.
Though I do have to say that it's mostly me being paranoid.
Hey Destin, it seems like you were pleasantly surprized by how this VR haptic glove exceeded your expectations by far. I think you must be the worst nightmare for this engineers developing the technology since you questions are deadly accurate and on rapid fire bombarding everything that they are supposed to keep secret! The only way to know more is to join the team (unfortunately you would still not be permitted to share new interesting things though).
Or just read the patent ;-)
Beyond 2000 was one of my favorite shows! How nice to remember :)
i love how you have great questions that really make them have to be careful as to how they answer. Its like you know what buttons to push
Can someone make a video about Destin's hand gestures? hahahahskkskd
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?
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?
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.
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
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.
I would love to see the code behind how they have tied the physics engine to their physical interface.. my first thought would be you would want to create an abstraction layer (an entirly new layer) that basically identifies all physical objects, giving them new properties, those properties would have information that sends to a new "touch engine" the touch engine would take input whenever your hand (or other parts that can "feel") touches any object, reading those properties and applying those to the engine..
that way you can just basically develop the code that applies all the properties to the touching mechanism... touch sensativity.. hardness.. softness... etc etc..
then just give rules to all the physical objects that hold these properties.
I'm a software engineer as well as a mechanical engineer, I love that all these different engineering worlds are coming together now..
I'm back at University doing neuroscience now with a minor is psychology, as I have moved in to Artificial Intelligence as my future focus...
Incredibly fascinating. Thank you for doing this! Very mind boggling but amazing how this machinery works and the enormous amount of work that’s gone into this.
I’ve never been so mesmerized by my sense of touch. I can’t stop touching things
