1. GLOBAL ACCESSIBILITY AWARENESS DAY 2025 Bitcoin Design - GAAD Workshop 2: Accessibility Testing, Tools, and Design Pattern Resources
2. WELCOME & INTRO Design for the edges, strengthen the core Can you setup your favorite bitcoin wallet using only a keyboard or screen reader? User testing is experiential, not just automated
3. TOOLS & RESOURCES Bitcoin Accessibility Guide https://jason-me.github.io/bitcoin-universal-design/
4. MANUAL TESTING: ANDROID • Enable TalkBack • Navigate app with gestures • Navigate using BT keyboard / Voice Access • Use high contrast or color inversion settings • Enable large text, magnification, and other accessibility shortcuts • Install Accessibility Scanner
5. MANUAL TESTING: IOS • Enable VoiceOver • Use rotor navigation and explore by touch • Enable dynamic type / bold text / increase contrast • Enable FKA (Full Keyboard Access) • Test Voice Control / Switch Control
6. MANUAL TESTING: DESKTOP • Navigate using keyboard only (Tab, Shift+Tab, Enter, Space) • Enable screen reader (JAWS, VoiceOver, NVDA, Orca, ChromeVox) • Zoom to 200% & 400%, enable high contrast mode • Use grayscale/color filters if available
7. LIVE TESTING DEMONSTRATION • App: Proton Wallet • Try: Initial setup, navigate home screen and main menu navigation using screen reader • Look for friction: Missing labels, inaccessible QR, illogical reading order, keyboard focus order
8. TESTING TOOLS (BROWSER) • Lighthouse: Chrome DevTools audit for accessibility (uses axe-core) • ARC Toolkit: Chrome DevTools (use TPGi ruleset) • Wave (WebAIM): In-page error and alt text diagnostics • Accessibility Insights: Guided testing for keyboard & landmarks
9. TESTING TOOLS (CONTRAST) • Stark (Figma): Contrast and alt text in design mocks • TPGi Colour Contrast Analyzer: WCAG ratio verification • APCA Contrast Calculator: Perceptual contrast rating
10. TESTING TOOLS (MOBILE) • Accessibility Scanner (Google): Manual scan suggestions • Android Accessibility Inspector: Node tree inspector • Xcode Accessibility Inspector: Apple’s iOS inspection tool
11. COMMON ACCESSIBILITY MISTAKES • Keyboard traps • Floating buttons • Missing text alternatives • Unlabeled buttons • Elements lacking visible focus • QR-only interactions with no alt text
12. ACCESSIBLE DESIGN PATTERNS • WAI-ARIA APG: Canonical source of accessibility patterns from the W3C. • Dialogs: role="dialog", aria-labelledby, aria-modal, focus trap • Buttons: , aria-label, aria-pressed • Disclosures: role="button", aria-label, aria- expanded, aria-controls • Landmarks: nav, main, region
13.
