I got nerd sniped by a great comment in a previous video. The idea was to make some kind of device to let blind people perceive their surroundings. The specific suggestion was to make some kind of a vest. Ultimately I ended up making an iPad case that uses the sensors in the iPad to perceive the surroundings and communicates through tactile feedback via a special hand grip. It was a fun project and turned out pretty neat.
I use a 13" iPad for all my technical drawing:

      The better option is have the camera as glasses that the blind person puts on and have either a glove or a small stick as the indicator of what is around you.

    Father to a blind son 6yrs old, turned blind 1,5yrs ago. He “watches” (listens) to his iPad regularly. Have been following your channel but this one I had missed, came up as a recommendation. People like you (and your supporting wife) gives me and my family hope that with tech everything is possible! And to all of you saying that a cane still is better, no, not to a kid that also wants cool tech! Thank you!

    My late father tried to do something similar to this 15 years ago. The final objective was to help blind people, but since he worked in aerospace, the first prototype was to have a warning system for astronauts so they could "see" on their backs with feedback through a vest. It never got past the part of cheking sensitivity, kinda like you do at 5:15... But yeah, it brings me memories.

    Dude, I sponsored several engineering student teams to do something similar to this 10 years ago. I stuck with an array of tactors (pancake motors) spaced 2-point-discrmination distance apart, and gave each tactor 3 bits of "depth" using PWM and current control. Note that a typical vibrotactile response scopes to only 8 JNDs (Just Notable Difference) so 3 bit depth just about covers what we can hapticly perceive. My initial designs were like yours, which morphed into a different form factor. According to my physiology research, I figured I could get a 64 tactor array. Not much but my form factor theoretically pushed the performance of that significantly. Sadly, this is one of my main back-burner projects that has not yet completed to a decent prototype stage. Sigh.

      @Nico Nico Except the stick wont tell you about head high obsticals in normal use. The stick is also distance limited to roughly one stick length.

    • David Hafen
      David Hafen

      So obviously having a PhD in all those things was an exaggeration, but to all the people who are saying, "You can do this without formal education by just getting your hands dirty", I could not disagree more. Being a self taught engineer will land you somewhere in the Michael Reeves category at best. You can still build really cool stuff, but your ability to really go beyond hobbyist projects is limited. If you watch any of this guy's videos, he is using vector calculus, differential equations, and linear algebra to solve incredibly complex problems and I guarantee any "self-taught" engineer won't have a clue how to do any of that. What makes him unique is being able to know how to actually utilize his formal education in practical applications. He's a "get your hands dirty" type of guy but with the skills of a highly trained engineer which allows him to make the most complex builds on youtube.

      @Nuhad What is more fraud to me is someone paying their way through a school taking classes that could have zero implementations in their work environment then expecting a company to come out of pocket to get them up to speed in the real world. HR hiring and training is one of the most expensive costs a company can make. Even more so in the engineering world because mistakes cost materials extra time and labor, and some times product delays. In the engineering world, and the drafting world. It is a team effort. So coming fresh out of college can hold the team back, and cause problems if not overly supervised. Having a incredible understanding of the industry, the product stack and work flow, as a test tech or assembler can go a long way into creating a faultless product. Most people can take up some form of drafting in high school. So the only thing college will teach you is physics and math on paper. Which does not always mean it will be correct off the paper. I’ve came across more than a fair share of engineers that, while understanding workflow in a program, lack common since and have severe over sights in application. Matter of fact I specifically remember having to stay over thanksgiving and work because a engineer messed up a top plate for a prototype demo that was being displayed after the holidays. He spent 3 days on it sent it to a partner to get CNC’d and it was all jacked up. I had to break out the drill press and some other shop equipment and go back through and correct his mistakes while sacrificing my holiday. He could not comprehend how it was wrong and was so wrapped up in his math that was wrong because of tolerances that I took him off the project and put him on something else because it was so time sensitive. Looked good on paper, but paper does not me jack. He also projected his measurements incorrectly. Another example engineer tasked with designing a label. Label was good. Looked ok. His first project. He sent it in and ordered it. Came back wrong color. 🙄 All because in the title block of the print he put green. Not understanding that that is such a wide term with so many meanings in color. He should of listed the hex or the rgb code he had on the print in DS CATIA. Little mistakes like that cost money. They are over sights that always happen. Working your way up in the field can teach a understand of these problems. Reading correct Prints in manufacturing can lead to a understanding of the standard the company uses, and so much more. On top of knowing how it comes together it boils down to a piece of paper does not mean crap until you learn the skills and can apply them to the job at hand. I’m of the personal opinion that they should not give a engineering degree or any degree just for being able to answer the square route of four. Our schooling system is incredibly flawed, and as much as I was proud of obtaining my position with my own intellectual prowess, and willing to apply learn, and listen. I still went a head ran through the system years later and got my shiny piece of paper that had almost no relation to the skills my company actually required. Being able to do the job is more Important than college otherwise you are leeching off people, and not a productive employee.

  • Mathman21

    You might be able to raise the resolution by using a pneumatic system that controls airflow to each individual pin, in addition to this you can move each pin much more precisely.

  • Julian Peters
    Julian Peters

    Excellent idea! I once heard of a research project where they used vibration-motors from smartphone arranged in a belt to tell you the direction in which to go. They would let the people walk around with it for a longer time (1 or 2 weeks) and continously lower the intensity. At some point the vibrations where so faint they could no longer be picked up conciously, which is akin to giving you an extra sense. I would probably try a newer version with something like this. And while you're at it: IF at some point Galileo comes online it would provide you with precise enough data from your surroundings. Augment that with information from a Google Glas, run optical flow on the video picture to get an estimate of collisions about to happen... That could work pretty seamlessly.

  • Carazy123

    Hey, as an engineering student, your workshop and ideas are really cool to me! I think it’d be nice if you had a video walking through your shop/tools, explaining what they’re for and how you went about building such an impressive shop! And, it could be a nice low-effort bit of content in-between more difficult projects. Just an idea!

    • Carazy123

      Jaden my college provides a limited membership to a local makerspace, and it’s totally worth it if you’re willing to put in the time. They had so much stuff there... I could literally learn to forge if I wanted to pay for it. It’s absolutely a mechanical engineer’s dream.

    • Jaden

      Agreed. I just finished college and I'd love to have a proper workshop one day but tools are expensive. I think for now I'm gonna spend money on a Maker Space membership instead. Most of them have the basic tools and a lot have CNC machines/3d Printers/Laser engravers and more.

      Eh, I'd argue the access for people to build anything has been diminishing as technology progresses. It requires increasingly specific (and expensive) machinery to make things compared to say the middle ages where you could make all your tools from scratch with wood iron and fire. Case in point, this guy dedicates a lot of his adult money tooling his workshop, as he said. And he's not exactly average in terms of wealth, much less on a global scale.

    Awesome video! Looking at this made me think - would it be possible to switch from mechanical sensor to sound. I imagine it like this: every fraction of a second a set of notes is played, representing what lidar sees at this frame, from left to right. This way note tone can represent height of the object, tone volume can represent distance from the object (louder = closer), tone length (if even possible to distinguish in such a small time) can represent width of the object, and spacing between notes can represent distance between objects from left to right.

  • SangokuKing

    You are an inspiration for when my motivation to study engineering goes down. Keep up the amazing, funny and clever video. Never been so entertained ! An idea for a second proof of concept for a phone format: Couldn't you magnetically push a thin layer of magnetic sand (or a film) onto the hand of the holder to reproduce the image you are seeing with a much better accuracy ? Might be impossible to do on a small scale tho. I am just throwing an idea.

    I've been thinking about a possible market-ready version of this, you can add some form of voice feedback too, this way you can combine this with image recognition, to inform the user of important things on the view. Maybe adding a button to send an instant image to a server to find and label objects and list them to the user via voice.

  • Matt Cruikshank

    Love the video. I'm curious if you could make "Iron Man Gloves" that sense distance to the closest object. So you could wander around, using your hands to "feel" how far away things are. So, put one LIDAR sensor on each hand, find the closest distance, translate that to either heat, or vibration from a motor, or use pneumatic pressure to squeeze your fingers... Or maybe each finger gets its own squeeze, so you cal "feel" as you run your fingers across an edge.

    Just now seeing this video and I had a weird thought. You know those pinart boards with a bunch of little plastic sticks that you can push in and out to make an image? Could you somehow implement that so that you could technically get a full imagine based on what you're pointing at and it pushed the pins in and out depending on the depth or whatever. Could that help or would it hinder it?

  • Flintstan

    I just got an idea for improvement you can have a glove that have magnets on its tips and in place of motors you can use tiny coils as electromagnets this allows the thing to be flayer,lighter and have higher resolution and I don't think it is that complicated to design

    Video suggestion: I am a mechanical engineer and have been playing around with an idea to improve hoverboards. They are intended to be an improvement on the Segway which was itself supposed to replace walking. The problem as I see it is really the lack of maneuvering on various surfaces. Solution, or at least what I think would work well, is to put some relatively large bottle rockets on some roller skates. You could even try them on one of those big slides at county fairs... I’m not an engineer. I went to business school.

      @polyrtm By subtracting where it is from where it isn't, or where it isn't from where it is, it obtains a difference, or deviation.

    @Stuff Made Here Thank you for the cool Video! What device and which software do you use to draw on it and visualize things? I think its very cool. Thanks for an answer, best regards :)

    What do you think about using Electromagnets on every single pin? Would give good resolution on the force of "pin pushing". Power delivery could be problematic though

    I remember reading How to Shoot Video That Doesn't Suck. Good book. A lot of obvious stuff but the emphasis of narrative is definitely true. You do a good job with that because of the whole invention journey thing.

    I've been thinking about these kinds of haptic feedback systems for a while and one question I've always wanted to ask an electrical engineer is if there's a safe way to use electricity as a feedback mechanism instead of going mechanical.

    • deathlis

      Absolutely. Electronic pulse massagers are already a thing. I don't know how much definition you'd get though, as they stimulate muscle, not individual nerve endings.

    Sorry I'm so late getting to this. I had a similar idea when I got my first iPad years ago after listening to a blind person talk about the brain's adaptivity when using echolocation. I didn't envision a mechanical device, however. I imagined an array of electrodes that would touch the skin and the voltage of each electrode would vary much like pixels on a display.

    Excellent. You could also incorporate sound - voice to notify how far to the next kerb; alarm to compensate for slow refexes; etc...

    Have you thought about using pneumatic actuators in the handle they can be very compact and you can have a large variation in the amount of pressure that they apply

  • Arran

    I remember reading electric current was being used for haptic feedback. Alternatively what about tiny solenoids? I think if you could get a better range of pressure you could learn to read it quite accurately.

      @johnson noel and the sad thing is u realise after a these years of study, u have not created anything novel, compared to people like him who already have lots of projects, and all u can do after graduation is just silently leave the STEM field alltogether, especially during this covid19 economical impact and end up with a normal 9to5 job, and I'm only a deliveroo rider on bike, so if u end up better than me, then great for u

      @johnson noel he is simply gifted, he is naturally given the aptitude to understand, to devise, to create.. That is why he is outstanding in these matters. Fewer excuses from schools, and accept the limits of oneself.

    So the tactile angle looks really interesting but, as you say, there's a learning curve to process that information for spatial navigation. Would it perhaps make sense to use sound as the output instead? Could use lidar to build a model of depth information and then convert that into a virtual sound stage, with each object producing a hum/tone/ broadband hiss as in the new vehicle reversing warning devices. Varying the difference in timing and amplitude between those sounds would give position and proximity data in an intuitive way. There would clearly be challenges- if a blind person is primarily relying on hearing for staying safe, the additional cues would have to be unobtrusive. Hopefully it could get to the point where the world just contains fewer silent obstacles. Could also, eventually, perhaps integrate machine vision to recognise objects and give them a characteristic sound- roadways, people, trees, changes in slope of the ground etc.? Next gen smart glasses could well have lidar, so the whole operation could be software if also used headphones with an awareness mode. Would have the advantage of leaving hands free for a cane/ carrying items- I'd be worried about someone tripping and being unable to break their fall with the ipad... But a truly fantastic job putting your device together: a commendable idea and very impressive execution
