What is Assistive Technology?
Assistive Technology (AT) refers to devices and software designed to help people with disabilities interact with digital and physical environments. In the context of web accessibility, it enables users to navigate websites, read content, and interact with web applications, regardless of their abilities.
Examples of Assistive Technology:
- Screen Readers (e.g., JAWS, NVDA, VoiceOver) – Read aloud on-screen content.
- Screen Magnifiers – Enlarge text or interface elements for low-vision users.
- Alternative Input Devices – Includes switch devices, eye-tracking systems, or adaptive keyboards used by individuals with motor disabilities.
- Speech Recognition Tools – Allow users to control interfaces with voice commands.
These technologies bridge the gap between complex digital interfaces and inclusive access for everyone.
Why Assistive Technology Matters in Web Accessibility
Websites must be designed to work seamlessly with assistive technologies. Without that compatibility, users with disabilities may not be able to access essential content or complete actions like submitting a form, navigating menus, or reading text.
This is why assistive technology is central to meeting accessibility standards like:
- WCAG (Web Content Accessibility Guidelines) – The global standard for digital inclusion.
- ADA (Americans with Disabilities Act) – U.S. law mandating accessible public digital services.
- BFSG (Barrierefreiheitsstärkungsgesetz) – Germany’s accessibility law is aligned with WCAG.
If your site doesn’t support assistive technologies, it fails to deliver equal access and risks non-compliance with legal mandates.
How to Support Assistive Technologies (for TYPO3, WordPress & Others)
Whether you're building in TYPO3, WordPress, or a custom web app, here’s how to ensure your site works well with assistive tools:
- ✅ Use semantic HTML – Elements like <button>, <label>, and <nav> give meaning to content for screen readers.
- ✅ Implement proper ARIA roles – When dynamic content is needed, use ARIA attributes carefully to describe interactions.
- ✅ Test with real assistive tools – Don't just rely on code validators. Use screen readers and magnifiers to audit the actual experience.
- ✅ Avoid mouse-only designs – Ensure all actions can be performed using a keyboard.
- ✅ TYPO3 Tip: Use accessible themes and add Accesstive TYPO3 Extension for enhanced compatibility.
- ✅ WordPress Tip: Choose themes labeled “Accessibility Ready” and test plugins for compliance.
Common Mistakes & Misconceptions
Let’s set the record straight:
❌ “Assistive tech users will adapt if my site isn’t perfect.”
✔️ They shouldn't have to. The burden of accessibility is on the developer, not the user.
❌ “I only need to focus on screen readers.”
✔️ No. Assistive tech includes a wide range of tools—you must support diverse needs, including mobility, cognitive, and low-vision requirements.
❌ “If it looks accessible, it is accessible.”
✔️ False. Accessibility requires functional compatibility, not just visual simplicity.

Key Takeaway
Assistive technology is not an edge case, it’s an everyday necessity for millions.
Building sites that work with assistive devices is not just about compliance, it’s about dignity, independence, and equal access. When you test and build with AT users in mind, you’re practicing true digital inclusion.
