A practical engineering primer on producing accessible PDFs — authoring choices in InDesign, Word and LibreOffice, the tag tree that PDF/UA actually requires, the four remediation tools engineers reach for, and how JAWS, NVDA, VoiceOver and ChromeVox each handle a tagged PDF differently.
presentations
A production primer for shipping accessible slide decks. PowerPoint's Accessibility Checker, Keynote's thinner toolkit, Google Slides' 2024 catch-up, and the web-first Reveal.js / Slidev / Marp route — with a decision tree for picking the right tool for the talk.
stem-diagrams
Chemistry molecules, biology cell structures, physics force diagrams, math function graphs — the production playbook for STEM imagery that screen readers, refreshable braille, and audio-description streams can actually consume.
braille
An end-to-end engineering tour of how braille actually gets made in 2026 — the software stack from Duxbury DBT and Liblouis to BrailleBlaster and RoboBraille, the embosser families from Index and Enabling Technologies, and the source-to-paper workflow that connects them.
epub3
EPUB3.3 is the format publishers will be measured against under the European Accessibility Act.
typography
A design primer on what the readability research actually supports — font choice (OpenDyslexic versus Atkinson Hyperlegible and Tiresias), line height, letter and word spacing, paragraph spacing, and the underrated levers of line length, alignment, and minimum font size.
math
An engineering primer on the state of math accessibility on the web in 2026.
audio-textbooks
How educational audiobooks are made in 2026 — the legacy DAISY pipeline, the new DAISY 4.0 specification, the ElevenLabs/Polly/OpenAI shift to AI narration, and the cost-quality trade-off that still separates a textbook from a podcast.
screen-readers
A staged learning path that takes a sighted developer from screen-reader novice to genuinely fluent — which reader to start with, the first-week monitor-off exercises, the developer shortcuts almost nobody teaches, and honest time-to-fluency benchmarks.
education
Twenty years after the CRPD recognised the right of deaf children to learn in a sign language, the gap between treaty and classroom is still measured in millions. A 2026 state-of-play across six countries, three teaching models, and the policy mechanisms beginning to close it.
tactile-graphics
A decision guide for producing tactile graphics in STEM education — raised-line drawings, swell paper, and 3D printing compared on cost, durability, complexity, and classroom workflow, with a per-subject decision tree.
