Learn how to design, test, and deliver WCAG-compliant interactive ebooks with accessibility features for inclusive, engaging elearning.
Nowadays, inclusivity in elearning is no longer an option; it’s becoming more and more essential. The diversity of today’s learners includes individuals with visual, auditory, cognitive, and motor impairments, as well as those who simply learn best through specific formats or styles.
That’s why ensuring every learner has an equal opportunity to engage with, comprehend, and benefit from the material is extremely important.
For elearning professionals in various fields, interactive ebooks have proven to be an effective way to deliver content that is both engaging and adaptable to different learners’ needs. When designed with accessibility in mind, they can give everyone a fair shot at education and training. As this guide to creating accessible ebooks explains, Accessible elearning isn’t a one-size-fits-all checklist; it’s a design mindset that influences every decision you make from the very beginning of your content creation process.
In this article, we’ll explore what accessibility means for interactive ebooks, how to design content that’s inclusive, which tools to use, and how to test your ebooks for accessibility.
What Standards Should You Follow for Accessible Digital Learning?
Before diving into the best practices for creating inclusive interactive ebooks, it’s important to understand the key standards that shape accessibility in digital learning environments.
The Role of WCAG
The Web Content Accessibility Guidelines (WCAG) are the gold standard for creating digitally accessible content. Currently, WCAG 2.1 and the upcoming 2.2 define how content should be perceivable, operable, understandable, and robust for all users. For interactive ebooks, these principles translate into:
- Perceivable: Content must be presented in ways that all users can easily perceive, such as providing alt text for images or captions for videos.
- Operable: All functionality should be accessible via keyboard navigation without requiring a mouse.
- Understandable: Content should be predictable in behavior and easy to follow by avoiding overly complex navigation or ambiguous instructions.
- Robust: Content must work with current and future assistive technologies.
How to Design Inclusive Interactive Ebooks for Accessible Elearning
It’s much easier to make your ebook accessible from the start than to fix it later. Here’s how to design inclusive digital content with inclusivity in mind:
1. Text and Visual Design:
- Add scalable text: Allow your users to adjust font size without breaking the layout.
- Use dyslexia-friendly fonts: Choose fonts like OpenDyslexic or Arial that are easier for readers to process.
- Include high-contrast themes: Ensure sufficient contrast between text and background (at least a 4.5:1 ratio for body text).
2. Multimedia Accessibility
- Add captions and transcripts: Provide synchronized captions for video and transcripts for audio.
- Include audio descriptions: For complex visuals, offer narrated descriptions that explain what is happening on the screen.
3. Navigation and Interactivity
- Have a logical tab order: Ensure a predictable order when navigating with the keyboard.
- Skip navigation Links: Let users bypass repetitive menus.
- Ensure accessible activities: Avoid drag-and-drop as the sole interaction method and offer other alternatives.
