Accessibility Statement

Commitment

Open Braille Beacon is an accessibility-focused project. We are committed to making this website as accessible as possible, targeting WCAG 2.2 Level AA compliance.

Current accessibility features

• Skip link — a "Skip to content" link appears on focus, allowing keyboard users to bypass navigation.
• Keyboard navigation — all interactive elements are reachable and operable via keyboard.
• Visible focus indicators — a distinct green outline (3px solid) appears on focused elements for keyboard users.
• Reduced motion — scroll animations and reveal transitions are disabled for users who prefer reduced motion (respecting the prefers-reduced-motion media query).
• Semantic HTML — proper use of headings, landmarks (header, nav, main, section, footer), lists, and ARIA labels.
• ARIA attributes — navigation regions, expandable menus, and interactive elements use appropriate ARIA roles and labels.
• Font choices — Manrope and IBM Plex Mono are selected for readability and clear character distinction.
• Responsive design — the site adapts to mobile, tablet, and desktop screen sizes.
• Alt text on images — all concept renders and visual elements carry descriptive alt text.
• Color contrast — text and background combinations are designed to meet AA contrast ratios.

Known limitations

• Concept renders as images — the site presents concept visuals (device renders, CAD sheets, system diagrams) as images. Alt text describes the general content, but fine-grained visual detail (dimension annotations, internal architecture labels) cannot always be fully conveyed in text equivalents.
• Navigation anchors on legal pages — links to sections on the main page (index.html#system, etc.) require the main page to be loaded; anchor targets do not exist on legal pages themselves.

We welcome suggestions for improving any of these limitations.

Ongoing effort

Accessibility is not a one-time checkbox. As the site and project evolve, we will continue to review and improve accessibility, including adding more detailed text alternatives for concept renders and testing with assistive technologies.
