This is a great start and idea tpsully. I don't know if you realize what you're trying to do or not, but effectively you're attempting to tap into the plasticity of the brain. The brain is astonishing in what it can do, and you use this more often than you think. For instance, you've probably heard the farmer puzzle where he has to cross a river in a small boat with a fox, a goose and a bag of beans, but he can only take one thing at a time because the fox will eat the goose, and the goose will eat the bag of beans. If you think through this puzzle for a few moments, whether you arrive at the solution or not, but look at how you are solving it, you'll notice you are visualizing the solution in your head. This is a major challenge to artificial intelligence because we are trying to mimic...
This is a great start and idea tpsully. I don't know if you realize what you're trying to do or not, but effectively you're attempting to tap into the plasticity of the brain.

For instance, you've probably heard the farmer puzzle where he has to cross a river in a small boat with a fox, a goose and a bag of beans, but he can only take one thing at a time because the fox will eat the goose, and the goose will eat the bag of beans. If you think through this puzzle for a few moments, whether you arrive at the solution or not, but look at how you are solving it, you'll notice you are visualizing the solution in your head. This is a major challenge to artificial intelligence because we are trying to mimic what the human brain does - but how on earth do you do mimic this astonishing visualization with algorithms?Yet the human brain visualizes things in other ways with other senses, for example, a blind person using a cane to navigate is visualizing the obstacles and terrain in their brain. So using the sense of touch, they can generate "sight" in their brain. One young man uses echolocation by clicking his tongue or listening to echoes from nearby noises:https://www.youtube.com/watch?v=r9mvRRwu5GwAgain, if you try to navigate your house either blindfolded or in the dark, you'll find you use this echolocation as well, even hearing the echo off the walls of your footsteps.The plasticity of the brain is extremely powerful in that it's been used to help deaf people to hear through their skin or "see" sound through their vision, or even allow blind people to see using their tongue:https://www.youtube.com/watch?v=OKd56D2mvN0The brainport simply takes advantage of the sensitivity of the tongue to electrical currents (stick a 9 volt battery on your tongue to find out) and all they do is paint a grid of electrical impulses on the user's tongue based on the black and white image from the video feed.So effectively what you are doing is tapping into this plasticity of the brain with your project, and attempting to help a blind person visualize their surroundings using the sense of touch, stimulated by your electronics. You mentioned adding sensors as a way to improve the system, and that is correct but even what you've done here is very smart and very useful, because you might find yourself surprised by how the plasticity of the brain uses the information generated. And you might be surprised by how quickly a blind person's brain learns how to use the system in ways you never thought of. Effectively what you've got is a one pixel sensor - but then so is a blind person's cane, and they can navigate and visualize their surroundings with remarkable clarity because of that "single pixel sensor."We see in stereo, so sure, just doubling your system and putting the vibration motors with one above each eye would probably add a surprising amount of depth perception. Your TOF sensors are extremely narrow which is very good because in tandem and looking at the end of a car for example, one sensor would be vibrating rather vigorously because it's detecting a close distance to the car. The other sensor is actually looking past the end of the car, so might not be vibrating at all because the next object it sees might be a tree 10 meters away. The user's brain plasticity will be very quick to learn even subtle differences between the two vibration motors, and for that matter, would even self-calibrate if the two vibration motors vibrated differently for the same distance! This is the astonishing power of brain plasticity. You add a whole mess of sensors and vibration motors (say 8 or 10) across the brow of the person, I expect we would all be surprised by how well a totally blind person would use it. You could also potentially use voice coils applying pressure to the skin instead of vibration motors. I don't honestly know how sensitive the skin would be to varying pressures, it would be a huge experiment.One practical suggestion on your setup, try using off-the-shelf glasses (sunglasses or the like) for the frame and set up. I tried making glasses in a project many moons ago, and learned real quick just how hard such a silly thing was. The ear hooks and even the front face frame become painfully uncomfortable really fast on home-built glasses. Whereas, going and spending $10 at Wally World gets me a pair of sunglasses that someone spent a lot of research and development on to make them confortable to wear long-term. Totally worth the money.But kudos for your project, I love it. Let us know if you test it out and how well it works! I know I for one will be very interested in hearing the results and feedback from a blind person.
Really good info! Thanks, I'll pass it along.
