The Myth of Accessibility Overlays
Overlays: The not-so-golden ticket to digital accessibility
In the realm of digital accessibility, a growing trend has emerged: the use of accessibility overlays. These tools, typically implemented as third-party JavaScript code, are designed to enhance the accessibility of websites by modifying their front-end code in real time. As more organizations strive to create inclusive digital experiences, it’s essential to delve into the intricacies of these overlays, their potential benefits, and the considerations involved in their adoption.
An important piece on this topic was written by our colleague, Kristen Witucki, who valiantly shared her personal experiences with overlays in her blog post, “Overlay Overconfidence.” Kristen’s insights have helped us understand just how crucial it is to accurately identify and address accessibility issues. It is essential that we get it right when working towards improving accessibility for all individuals.
At first glance, overlay tools seem like a quick and efficient fix to accessibility issues. After all, they often promise instant compliance with standards like the Web Content Accessibility Guidelines (WCAG). However, as I dove deeper, I discovered that the reality is far from this promise. The following are why overlays are not the golden ticket to digital accessibility.
1. Overlays are a band-aid, not a cure
Picture having a roof with a leak. Instead of fixing the root cause of the leak, you simply put a bucket under it to catch the dripping water. This is exactly what overlays do. They attempt to patch accessibility issues without addressing the underlying problems in the website’s design or code. True accessibility is achieved when integrated into the foundation of a website, not slapped on top as an afterthought.
2. One size does not fit all
User’s needs are unique. Overlays often take a one-size-fits-all approach, which leads to an inferior user experience. For instance, a visually impaired user relying on a screen reader is likely to encounter issues if the website’s content isn’t structured correctly, regardless of the overlay in place. As Kristen’s experience has demonstrated repeatedly, the overlay doesn’t just get in the way, it doesn’t work for her.
3. Over-reliance on automation
While automation can detect some accessibility issues, it’s estimated that it can catch anywhere between 40-60% of potential problems. Overlays heavily rely on automated scans, leaving a significant portion of issues unaddressed. Human judgment and manual testing are crucial to ensuring a website is truly accessible.
4. False sense of compliance
Many providers who push overlays promote that their solutions guarantee compliance with standards like WCAG. However, accessibility is not just about ticking boxes. It’s also about usability and ensuring that everyone, regardless of their abilities, can access, understand, and interact with digital content. Overlays can give organizations a false sense of security, leading them to believe they’re compliant when, in practice, they are far from it.
5. Potential legal implications
Several companies relying solely on overlays have faced lawsuits for not being genuinely accessible. Overlays can’t promise immunity from legal repercussions. In fact, they might even draw attention to the fact that a company is aware of its accessibility shortcomings but chose a shortcut instead of a reliable solution. Organizations that choose this route for digital accessibility do so at heightened risk.
6. Missed opportunities for better design
When we design with accessibility in mind from the outset, we often end up with a better product for everyone. Overlays can deter organizations from embracing inclusive design principles that benefit all users, not just those with disabilities.
The future of digital accessibility is not an overlay.
Digital accessibility is not just a matter of compliance. It’s a matter of usability, inclusivity, empathy, and thoughtful design. Although overlays are tempting with their quick-fix promises, they fall short of providing reliable accessibility solutions. Become more informed on the significance of designers, developers, and organizations that invest in creating truly accessible websites from the ground up. The digital world should be for everyone, and shortcuts won’t get us there.
