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:
Parts used in this build:
2020 iPad pro 13":
Apple pencil:
Teensy 3.6:
Pancake stepper:
Leadscrew stepper:
Stepper drivers:
Books that I've read to learn many of the skills used in this project:
Real time collision detection:
Introduction to algorithims:
Planning algorithims:
Computational geometry:
Other tools and things that I think are great:

      Going forward with your interesting invention keep in mind that there is a braille literacy crisis in the US, where fewer than 10% of the 1.3 million people who are legally blind can read braille, this applies to both adults and children.

    maybe instead of (or along with) the tactile feedback, you could have auditory feed back where a voice actually tells you the distance seperating you from an object or a wall.

    I wonder if you could convert the sensor feedback into audio somehow. They have 3d headphones these days, you could have a button to send out a ping and hear it just like echolocation. I've been watching Daredevil recently.

    I know this video is like an overdue baby old but I have to say it, this could really and truly be an amazing product. Obviously it's far too intricate atm to be ready for massproduction, but I swear you could make this happen. It could be in a phonecase now (though you'd probably need some decals so people know you are not filming them), probably would also work in a cane or for the older blind people, in the handles of a walker. This could legit change the quality of life for many folks, please consider developing it further. It costs like $25,000 to train a seeing eye dog? Surely you could get this to cost less than that. Might need to add a battery pack that you clip on your belt because battery drain would be a real thing.

    Depth sensing: project an infra red grid of dots. View them with a digital camera filtered to see the dots. The closer the dots are to each other, the closer the objectthey are hitting is. Can't see the dots then there is nothing there. I don't know how líder works but I assume it is something like this.

  • Lucas Foster

    Perhaps solenoids, or hydraulic/pneumatic actuators? You can get solenoids super tiny, or even push wire out the cylinder with tiny motors for each wire, instead of larger rods

    fuck. with the technology of Google glasses, there's no reason you can't set this up in some sort of Eyewear with Bluetooth to the product. the Eyewear will also give the person the feel of site, as they will be "seeing" with there hands where ever there head is pointed. The glasses could have a battery/spot for your techy stuff right over the ears simular to how hearing aids are.

    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.

    ya could had used voice? it could had said object right or left, object infront. But i ques ya were not able to make a stabbing vest so ya went to stab fingers! Edit: And even ask user height so it could say that hallway is not tall enuff or that Stairs ahead! going down/up. Street lights color, by img detection, i think some blind people would even use it, basically like complex blind people GPS, listen music and get instructions.

    What kinda idiot introduces all of their security system to millions of people? In security circles it's usually called a foolish move. Even if it speaks of your confidence, it could be misplaced as all security systems can be exploited, and you just made it easier. That's why there's a saying about how the smartest people are also some of the dumbest ones.

    I imagine a design to fit in a phone case could utilize the same technique that phones use for their vibration motors. That way you don't re-invent the wheel. Possibly a longer adaptation of it or multiples of already manufactured ones each with their own corresponding ball or pin for textile feel on a slimmer case. It could even draw the power directly from the phone since the voltage and wattage can remain very low
