AI and Accessibility Remediation: Bridging the Gap

AI is changing how we handle accessibility on the web. This topic is especially relevant as more businesses are looking to improve their online accessibility. AI tools can now find common accessibility failures, explain them, and even suggest fixes. But there's a crucial gap: while AI can detect issues, it doesn't always know the best way to fix them.

What is Accessibility Remediation?

Accessibility remediation refers to the process of fixing issues on websites to make them usable for people with disabilities. This often involves following guidelines known as WCAG (Web Content Accessibility Guidelines). These guidelines help ensure that websites are accessible to everyone, including those who use assistive technologies like screen readers.

AI's Role in Accessibility Remediation

AI tools are becoming more capable in identifying WCAG violations. They can spot issues like missing alt text, poor color contrast, and unlabelled forms. In a recent project involving a Shopify storefront, an AI assistant was able to identify several bugs that would have taken much longer to find manually. It recognized the right interaction patterns and even reviewed existing code for errors.

Limitations of AI-Generated Fixes

However, AI-generated fixes can sometimes miss the mark. In the Shopify example, the AI suggested moving search suggestions to a separate area that could be reached by pressing the Tab key. This sounds reasonable at first, but in a combobox, pressing Tab typically moves focus out of that widget. This could confuse users who are navigating suggestions with their keyboard.

Another suggestion involved mixing different types of actions in the same listbox. Some options would navigate to a product page, while others would rewrite the search query. Although visually distinct for sighted users, the AI's proposed interaction model did not account for how assistive technology users would experience it. The better approach was to rethink the interaction entirely rather than trying to make the existing one more accessible.

The Importance of Human Oversight

The real risk with AI-generated fixes is that they can appear just as fluent and confident as correct solutions. If someone lacks a deep understanding of how these interactions work, they might implement a fix that doesn't truly enhance accessibility. The AI understood the visual aspects and standards but failed to reason through how these changes would communicate to users of assistive technology.

Human expertise is essential in evaluating AI-generated solutions. Engineers must assess whether the proposed fixes align with the intended user experience and meet accessibility standards. It's not enough for AI to simply detect issues; we need to ensure that the fixes genuinely improve the experience for users.

How Should We Use AI?

We shouldn't dismiss AI as useless. It can identify real bugs, explain standards, and draft code faster than many of us could do manually. The key is to keep AI as a part of the remediation process, but not the final decision-maker. Engineers and accessibility experts should always review AI's suggestions to ensure they fit within the actual context of the application.

The goal is to leverage AI's strengths while maintaining human judgment in areas that require context and understanding of user experience. AI can tell us what's broken and even suggest how to fix it, but it shouldn't be the final authority on whether we've truly improved the experience for the people we're building it for.

Conclusion

AI is a powerful tool in the quest for better web accessibility, but it should complement, not replace, human expertise. While AI can effectively identify issues and suggest fixes, it lacks the nuanced understanding needed to ensure those fixes truly enhance user experience.
