Make this. Somebody make this. Maybe it's not the obnoxious, catch-phrasey SaaS bulls*t you wanted to do, but it will change the world and you can be proud that you made it. There are millions of blind people in the world. They shuffle around with rudimentary technology. Literally sticks. But they still have ears. Synesthesia. Process the visual 3D world with a camera. Use head tracking. Convert it into an immersive three-dimensional auditory world. A curb sounds like a stream. A tree sounds like rustling leaves. A pole is an electric arc. Traffic lights are pings. Red lights, walk signs all have a distinctive sound replicated in 3D auditory world that maps as closely as possible to the actual world. We have the technology. You can build it. Not only would it radically improve the lives of blind people, it would be a blast for the sighted to design and refine. Like a real life video game that actually matters to someone.
