Walk Narrator

Audio descriptions of your surroundings as you walk

Useful

The Problem

Visually impaired people struggle with unfamiliar environments; tourists miss context

Current Solutions (Not Great)

Human guides (expensive, scheduled), basic screen readers (don't see environment), audio tours (fixed routes)

Who Needs This

Visually impaired users, tourists, urban explorers, elderly with declining vision

Walk Narrator turns your phone into an AI tour guide that sees through your camera and narrates what's around you. Point it at buildings, signs, scenery—it describes what it sees and adds context. Perfect for visually impaired users navigating new areas, tourists who want hands-free information, or anyone who wants to experience their neighborhood with fresh eyes. Works offline once the model is loaded, so it's useful abroad without data.

Honest Take

Genuinely impactful for accessibility, addressing a real pain point for visually impaired users. Technical challenge is running real-time vision models on-device without draining battery, and accuracy needs to be extremely reliable for safety. Competition exists (BeMyEyes, Seeing AI) but there's room for a free, offline-first option.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Walk Narrator' using WebInfer vision model, MediaDevices, and Web Speech API. UI: minimal—large start/stop button, volume control, verbosity slider, mostly runs in background. Use getUserMedia({ video: { facingMode: 'environment' } }) for rear camera. Capture frame every 2-3 seconds. Use vision model with generateObject to return { scene: string, objects: [{ name: string, position: 'left'|'center'|'right'|'ahead', distance: 'near'|'medium'|'far' }], text: string[], hazards: string[], pointsOfInterest: string[] }. Prioritize narration: hazards first, then changes from last frame, then new objects. Use speechSynthesis with appropriate rate/pitch. Add Geolocation context for richer descriptions. 'Quiet mode' only announces hazards and significant changes. Test with screen reader users for accessibility.
