Every day, the importance of inclusion in the design of websites, applications, and web content becomes more obvious. Organizational digital properties must be accessible to over 15% of the world population living with a form of disability, most of which affects their use of the web. This applies to both government agencies and private-sector organizations and why many countries have legislated non-discrimination or accessibility laws, and even digital accessibility laws. Examples of these include the Americans with Disabilities Act (ADA) and Section 508 in the United States where about 26% of the people are disabled. Europe has EN 301 549, the U.K ensures equal access with the Equality Act of 2010 (EQA) while AODA currently stands out among many provincial laws in Canada.
U.S web accessibility lawsuits have continued to grow in 2020, with an increase in state-filed accessibility suits and app-related legal claims opening organizations to financial liabilities and damage to brand reputation. Hundreds of organizations (especially in retail businesses and the food industry) are being targeted for non-compliance with the ADA, yet accessibility remains a problem; which can be attributed to a lack of knowledge or negligence.
There are many approaches to digital accessibility solutions to help organizations achieve compliance with automated solutions becoming the most prominent one in recent years. For any website to be accessible, it must conform with the most current version of the Web Content Accessibility Guidelines (WCAG). The WCAG standard not only helps make web content accessible to people with disabilities, it also ensures web content is more usable in general and across multiple devices.
As a more updated version of the guideline, WCAG 2.1 clearly provides a wide range of recommendations for making web content more accessible to a wider range of persons with disabilities; including visual and hearing impairments, those with limited movement, learning, and cognitive limitations.
Accessibility should be incorporated early to achieve accessible web design and development. Early adoption will require an accessibility audit– a detailed report and a holistic view of your digital products’ accessibility. The report is to be used by your IT team to manually remove accessibility barriers. The concept of remediating your site is referred to as a manual accessibility solution. As the oldest form of making a website accessible, it is reliable but takes time.
Accessibility Tool-based Overlays
Accessibility toolbars specifically help users personalize the website based on the individual’s requirements and experience your site as they deem fit. However, the accessibility toolbar alone does not and cannot fully make any website WCAG-compliant. They can only be useful to users with partial impairments since a totally blind user cannot see the text on the site let alone decide if the font is too small or the contrast between text and background is too low.
Since custom overlay auto-remediates, website visitors will only see a fixed website, unlike the tool-based overlay. Once the site loads, web users, including assistive technologies (e.g screen reader) users, will be able to navigate the website without needing to manually tweak the accessibility options.
Use Cases for Overlays
Accessibility overlays on websites are meant to address visual accessibility issues. Advanced overlays can add text alternatives to the page or add missing accessibility semantics without touching the underlying source code of your website or application although not reliably fixable. It’s most appropriate use case would be supporting an already-remediated site.
The Overlay Argument
Ideally, development teams should be writing or rewriting source code that complies with WCAG 2.1 AA success criteria. Incorporating accessibility from the very beginning (of the development process) is known as a “shift left” approach within the accessibility industry whereas “shift right” is the application of accessibility overlays for quick-fix and leaving accessibility to the end of the process. However, leaving accessibility late should not mean the end of the world.
Overlays are especially essential for quick-fix. They are most useful when there is a threat of legal complaint or lawsuit to remind your organization about the need for your website to be accessible to persons with disabilities. Accessibility overlays can’t fix all of the accessibility violations on the site (even with the power of artificial intelligence and machine learning techniques).
With all said, one shouldn’t be quick to write-off the advanced solution because they are part of an overall solution. They offer innovation and efficiency and serve as entry points in form of website testing, to be supported by manual website testing, monitoring, and expert adjustments.
For clarity, automated tools are supposed to augment manual accessibility testing and adjustments efforts, not replace them.
