Accessible Chemical Diagrams

We provide technology to turn simple chemical molecule diagrams into enriched data files, allowing for an interactive, fully accessible experience using modern web standards.

Our tech enables the direct translation of images (and other common industry standard file formats) into fully web-accessible SVG diagrams. Readers can listen to descriptions of the diagram as well as interact with them to explore them in depth. We support navigation on several levels as well as magnification, contrast changes, different colorschemes, and internationalization.

With us, there’s no need to prepare diagrams in special programs, or for readers to learn new tools; everything we do is built around HTML5, and is easily embeddable in web pages, ebooks or digital textbooks. We’re fully platform independent, we support all modern browsers and many screen readers, so you can give your customers the best possible experience.

It’s simple to get started, check out our fully automated content-conversion workflow - just upload an image of your choice, and start converting your chemical diagrams now!

You can also try out our API, available at https://api.progressiveaccess.com for easy integration into your own content pipelines:

Interactive Molecule Exploration

These accessible, annotated diagrams can be easily connected to web-based interactive exploration software, which offers screen reader support and magnification. All interactive diagrams have been automatically generated from original bitmap images.

You can find the interactive examples below:

• Methylpentene (original)
• 2-bromo-1-chlorobutane (original)
• Aspirin (original)
• Benzoic Acid (original)
• Siramesine (original)
• Ovalene (original)
• Paracetamol (original)
• Aspirin (multi-lingual) (original)

You can find more examples in our Chemistry examples directory.

Presentations and Resources

We’ve given workshops and talks on how to use our tools for creating our interactive diagrams. If you’re interested, take a look at our collection of slides, resources and other diagrams.
