Accessible Design Guide: Practical Braille Reading Tips for Inclusive Spaces

Two Essential Guidelines for Incorporating Braille Fonts in Inclusive Design

🟡 Mastering Braille Accuracy (Navigating Polyphonic Characters)

National Common Braille follows Hanyu Pinyin principles, constructed through syllable spelling and word segmentation. When working with Braille fonts, polyphonic characters present a frequent challenge. Implement a smart proofreading feature that cross-references Pinyin-Braille mappings to minimize errors. For guaranteed accuracy, always have certified Braille specialists perform final verification.

💡 Pro Tip: Conduct initial spelling checks using dual-font systems (like Ali Health 2.0) before final conversion to pure Braille.

🟡 Optimizing Braille Legibility (Perfecting Font Specifications)

National Common Braille’s tactile dot system is scientifically designed for optimal blind readability. Each raised dot features either a hemispherical or parabolic shape, with precise dimensions:
• Base diameter: 1.0–1.6 mm
• Dot height: 0.2–0.5 mm
• Dot spacing: 2.2–2.5 mm
• Cell spacing: 3.5–3.8 mm

💡 Design Recommendation: Achieve authentic Braille slate results by using:
• 28.6 pt font size
• 32 pt line spacing
• Zero character spacing
