Building Augen: AI Vision for Accessibility
Building Augen has been one of the most rewarding and challenging projects of my career. Creating an AI-powered vision assistant that truly serves the accessibility community required not just technical expertise, but a deep understanding of user needs and inclusive design principles.
The Accessibility-First Approach
From day one, Augen was designed with accessibility as the core requirement, not an afterthought. This meant:
Screen Reader Compatibility
Every interface element needed to work seamlessly with screen readers. I spent countless hours testing with NVDA, JAWS, and VoiceOver to ensure the experience was smooth for users who rely on these tools daily.
Keyboard Navigation
The entire application is fully navigable using only keyboard input. This wasn’t just about adding tab indexes - it required careful consideration of focus management and logical navigation flow.
Voice-First Interface
The primary interaction method is voice commands, making the visual interface secondary. This flipped traditional UI/UX thinking on its head and led to innovative design solutions.
Technical Challenges
Real-Time Computer Vision
Integrating AI vision APIs while maintaining responsiveness was complex. I implemented a queuing system that processes images efficiently without blocking the user interface, ensuring smooth voice interactions even during intensive vision processing.
Multilingual Speech Processing
Supporting 12 languages meant dealing with various speech recognition quirks and text-to-speech quality differences. Each language required fine-tuning and cultural consideration for natural interaction patterns.
Progressive Web App Architecture
Building Augen as a PWA enabled offline functionality and app-like experience across devices. The service worker implementation handles caching strategies for AI model data while maintaining fresh content updates.
User-Centered Development
Community Feedback
Regular testing sessions with visually impaired users revealed assumptions I didn’t even know I was making. Their feedback shaped every major feature and interaction pattern in the application.
Iterative Improvement
Each deployment cycle includes accessibility audits and user feedback integration. The current version represents dozens of iterations based on real-world usage scenarios.
Impact Measurement
Augen currently serves users across 8 countries, with particularly strong adoption in educational settings where it serves as a learning tool for spatial awareness and independence skills.
The project has opened doors to collaborate with accessibility organizations and has informed my approach to inclusive design in all subsequent projects.
Next Steps
Future development focuses on:
- Mobile app for iOS and Android
- Enhanced object recognition for specific contexts
- Integration with smart home systems
- Educational partnerships for training programs
Building Augen taught me that accessibility isn’t a feature - it’s a fundamental design principle that makes technology better for everyone.
