Как создать Facebook для слепых людей

Core Principle

Не создавать separate app. Вместо этого: make Facebook accessible for blind users (WCAG 2.1 AA+ standard).

Key Features

1. Screen Reader Optimization

• Alt text для ВСЕХ images (не optional)
• Semantic HTML: proper headings, buttons, links
• ARIA labels для custom components
• Test: NVDA, JAWS screen readers

2. Audio Descriptions

• Post с photo: auto-generated alt text (AI vision)
• Video: include captions + audio description
• Format: "[Image: sunset over ocean]" not just "image.jpg"

3. Keyboard Navigation

• All features accessible via keyboard (no mouse required)
• Logical tab order
• No keyboard traps

4. Content Recommendation

• Posts: "Which posts matter to me?"
• Audio feed: Daily summary read aloud
• Topics: "What are friends talking about?"

5. Voice Input

• Post via voice: "Record a post"
• Search: "Find posts about..." (voice command)
• Navigation: "Go to messages"

Metrics

• DAU from blind/low-vision users
• Accessibility audit score (WCAG compliance %)
• NPS from accessibility community
• Feature usage vs sighted users

Why This Matters

• ~43 million blind people globally
• 1B+ people with vision impairment
• TAM: huge, untapped
• Competitive advantage: Facebook already has data, just needs to unlock it

Bottom line

Accessibility = growth + ethics + competitive advantage
