Tech Accessibility: A Practical How-To for Everyone

Making technology accessible isn’t just a nice thing to do; it’s a necessity for inclusivity and often a legal requirement. But how do professionals ensure their digital creations are truly accessible? Neglecting accessibility is not only unethical, but can also limit your reach and potentially open you up to legal issues. Let’s walk through practical steps to make your digital world more inclusive.

1. Understand the Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) are the gold standard for web accessibility. These guidelines are developed by the World Wide Web Consortium (W3C), and they provide a comprehensive framework for making web content more accessible to people with disabilities. There are different levels of conformance: A, AA, and AAA. Aim for at least Level AA, which is widely considered the minimum acceptable standard. WCAG covers a broad range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

Familiarize yourself with the four principles of WCAG, often remembered by the acronym POUR: Perceivable, Operable, Understandable, and Robust. Each principle has guidelines and success criteria that provide specific, testable requirements.

Pro Tip: Don’t try to tackle WCAG all at once. Start with the most common and impactful guidelines, such as providing alt text for images, ensuring sufficient color contrast, and using proper heading structure.

2. Optimize Documents for Screen Readers

Many professionals create documents using tools like Microsoft Word or Adobe Acrobat. These documents must be accessible to users who rely on screen readers. Here’s how:

1. Use Styles: Instead of manually formatting headings, use the built-in heading styles (Heading 1, Heading 2, etc.). This creates a logical document structure that screen readers can navigate. In Word, find the Styles pane on the Home tab.
2. Add Alt Text to Images: Right-click on an image, select “Edit Alt Text,” and provide a concise description of the image. Be specific and relevant. For example, instead of “image,” use “Diagram showing the organizational structure of Fulton County government.”
3. Check Accessibility: In Word, go to File > Info > Check for Issues > Check Accessibility. This tool will identify accessibility errors and provide recommendations for fixing them. In Acrobat Pro, use the Accessibility tool (Tools > Accessibility) to run a full check.
4. Set Document Language: Go to File > Options > Language and set the document’s language. This helps screen readers pronounce words correctly.
5. Create Accessible Tables: Ensure tables have header rows and avoid using tables for layout purposes. In Word, select the table, go to Table Design, and check the “Header Row” box.

Common Mistake: Forgetting to run the accessibility checker before sharing documents. This simple step can catch many common errors.

Here’s where to find the Accessibility Checker in Microsoft Word.

3. Caption Your Videos

Video content is incredibly popular, but it’s useless to someone who can’t hear. Captions are essential for making videos accessible to people who are deaf or hard of hearing. Many platforms offer automatic captioning, but these are often inaccurate and require editing. Take the time to review and correct captions for accuracy.

1. Use a Captioning Tool: Platforms like YouTube and Vimeo have built-in caption editors. Alternatively, professional captioning services can provide accurate and timed captions.
2. Ensure Accuracy: Review and edit captions to ensure they accurately reflect the spoken content. Pay attention to homophones (e.g., “there,” “their,” and “they’re”) and proper nouns.
3. Synchronize Captions: Ensure captions are synchronized with the audio. Captions that appear too early or too late can be confusing.
4. Consider Open Captions: Open captions are always visible and cannot be turned off by the viewer. This ensures accessibility regardless of the platform or device.

Pro Tip: When creating video content, speak clearly and at a moderate pace to make it easier for captioning tools to transcribe accurately. Also, provide a transcript of the video content for people who prefer to read.

4. Design with Color Contrast in Mind

Color contrast is a critical aspect of visual accessibility. People with low vision or color blindness may struggle to read text if there isn’t sufficient contrast between the text and background colors. WCAG requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. There are many free online tools to check color contrast, such as the WebAIM Contrast Checker.

1. Use a Contrast Checker: Enter the foreground and background colors into a contrast checker to verify that they meet WCAG standards.
2. Avoid Problematic Color Combinations: Certain color combinations, such as red and green, are particularly problematic for people with color blindness.
3. Provide Alternative Visual Cues: Don’t rely solely on color to convey information. Use text labels, icons, or patterns to provide alternative visual cues.

We had a client last year who launched a new website with insufficient color contrast. They received complaints from users with low vision and were eventually threatened with legal action. After a costly redesign, they learned the importance of prioritizing accessibility from the outset.

Common Mistake: Assuming that if you can see it, everyone else can too. Always test your designs with accessibility in mind.

5. Make Your Website Keyboard Accessible

Some users cannot use a mouse and rely on keyboard navigation. Your website must be fully navigable using only the keyboard. This means ensuring that all interactive elements, such as links, buttons, and form fields, can be accessed and activated using the Tab key, arrow keys, and Enter key.

1. Check Tab Order: The tab order should follow a logical sequence that matches the visual layout of the page.
2. Provide Visual Focus Indicators: When an element receives focus, there should be a clear visual indicator, such as a highlighted border, to show the user where they are on the page.
3. Avoid Keyboard Traps: A keyboard trap occurs when a user can tab into an element but cannot tab out of it. This is a major accessibility barrier.

6. Use ARIA Attributes When Necessary

ARIA (Accessible Rich Internet Applications) attributes can enhance the accessibility of dynamic web content and custom controls. ARIA provides additional semantic information to screen readers, allowing them to understand the purpose and state of elements that are not natively supported by HTML.

Consider the ethics involved as you implement accessibility features.

1. Use ARIA Sparingly: ARIA should be used only when necessary to supplement HTML semantics. Overusing ARIA can create more problems than it solves.
2. Understand ARIA Roles, States, and Properties: ARIA roles define the type of element (e.g., “button,” “menu,” “dialog”). ARIA states describe the current condition of an element (e.g., “aria-expanded,” “aria-disabled”). ARIA properties provide additional information about an element (e.g., “aria-label,” “aria-describedby”).
3. Test with Screen Readers: Always test your ARIA implementation with a screen reader to ensure it is working as intended.

Pro Tip: Before using ARIA, ask yourself if there’s a native HTML element that can achieve the same result. Native HTML elements are generally more accessible and require less effort to implement.

7. Test, Test, Test

The most important step in ensuring accessibility is to test your work with real users who have disabilities. Automated testing tools can identify some accessibility issues, but they cannot replace the insights of human testers. Recruit users with a variety of disabilities to test your websites, documents, and applications. Ask for feedback and use it to improve your accessibility practices.

1. Use Automated Testing Tools: Tools like axe DevTools can automatically scan your website for accessibility issues.
2. Conduct Manual Testing: Manually review your website using a keyboard and screen reader to identify issues that automated tools may miss.
3. Involve Users with Disabilities: The best way to ensure accessibility is to involve users with disabilities in the testing process. Their feedback is invaluable.

Here’s what nobody tells you: Accessibility is an ongoing process, not a one-time fix. The digital world is constantly evolving, and your accessibility practices must evolve with it. Regularly review and update your accessibility guidelines to ensure they remain current and effective.

Consider this case study: A local Atlanta-based non-profit, “Tech Forward,” partnered with us to improve the accessibility of their online job application portal. We started by conducting an accessibility audit using axe DevTools, which identified over 50 accessibility violations. We then worked with a team of testers, including individuals with visual impairments and motor disabilities, to manually review the portal. Based on their feedback, we made several changes, including improving color contrast, adding alt text to images, and ensuring keyboard navigability. After the changes, the number of completed job applications from individuals with disabilities increased by 40% within three months. The portal is now fully compliant with WCAG 2.1 Level AA.

Accessibility isn’t just about compliance; it’s about creating a better experience for everyone. If you’re in the Atlanta area, you can find resources and support from organizations like the Georgia Tech Assistive Technology Research and Development Lab. They offer training and consultation services to help organizations improve their accessibility practices. If you are a small business fighting back, make sure you take advantage of any regional assistance programs available.

By prioritizing accessibility, professionals can ensure that their technology reaches the widest possible audience. Start small, be consistent, and never stop learning. Make accessibility a core value in your work, and you’ll create a more inclusive and equitable digital world. Don’t wait until it’s a legal mandate; make the change today.
