Design a Product for Blind Users

I would design an app called 'EchoGuide' focused on autonomous indoor navigation for blind users. First, I'd identify the core pain point: standard GPS fails indoors where orientation is critical. Leveraging Apple's ecosystem, EchoGuide would utilize LiDAR sensors on newer iPhones to map room layouts in real-time. The interface would be entirely voice-first, designed strictly for VoiceOver compatibility, ensuring all interactions work without visual cues. A key feature would be 'Audio Beacons,' using spatial audio to guide users toward exits or specific objects via directional sound cues. We must also integrate seamlessly with Siri for hands-free control, adhering to Apple's privacy standards by processing sensor data locally on the device. To ensure accessibility, the UI will support Dynamic Type automatically and avoid color-only indicators, relying instead on shape and haptic feedback. Finally, I would validate this by partnering with local blindness advocacy groups for beta testing, iterating based on their feedback to ensure the haptic rhythms feel intuitive rather than overwhelming. This approach balances cutting-edge hardware capabilities with deep respect for user dignity and independence.
