An AI Assistant for Reading Signs and Finding Your Way

What if we made a mobile app that could read signs, directional markers, information plaques, building numbers, street names, wayfinding boards, and all the other text surrounding us in cities, stores, malls, hospitals, airports, and train stations?

My distance vision is not what it used to be. I am not sixteen anymore, and I often cannot make out the words on a sign or plaque. An app that could read letters, directions, warnings, room numbers, department names, and all the other informational clutter of urban life could be useful enough to deserve a spot on the first screen of any phone.

The interface would be simple: essentially a camera, except it would not take pictures. Instead, it would recognize what it sees. Wherever it detected patterns typical of informational signage, it would classify them, perhaps as street signs, business names, directions, room numbers, warning signs, route diagrams, display boards, or kiosks. It would then extract the text, show it clearly on the screen, and read it aloud if needed.

Add semantic filtering and the app could do more than dump all the recognized text on screen. It could surface what actually matters: which way to go, where the entrance and exit are, which room or department you need, where to find the checkout, bathroom, bus stop, street, or business. This would be more than optical character recognition: a personal interpreter of the built environment.

The business model seems straightforward: partnerships with shopping malls, airports, train stations, hospitals, universities, museums, city services, and companies that want their signage and navigation to be accessible to people with impaired vision.
