I generally test four keyboard shortcuts, as they cover most of the WCAG 2 AA requirements: to navigate focusable elements, to read each item, to read each image, and to navigate headings. If something behaves unexpectedly or stands out as difficult to use, then it’s worth bringing up to the team for further investigation. It’s important that a user with vision disability can understand the content and easily navigate the page - primarily using a keyboard - with the same ease that a person without vision disability can. When in doubt, I ask myself whether an interaction behaves the way I designed it to. It is irrelevant to them whether the most important content is visually in the middle with the boldest colors and most artistic design.” They don’t often think in terms of left and right or position on the page. “Most screen reader users cannot survey the entirety of a web page with such immediacy.

The first step is to enable your screen reader and get familiar with its keyboard shortcuts. I’ll provide guiding questions and examples of good and bad interactions, so your OS shouldn’t matter. If you’re on Windows, you can use JAWS or NVDA. Setting up your screen readerįor this guide, I’m going to use VoiceOver on Mac, a screen reader program that comes on new Mac computers, iPhones, and iPads. I wrote this to make auditing easier with helpful links for further reading. It is an assistive tool so people’s usage varies based on their individual needs. I find screen reader usage to be tricky because there’s no single tool to automatically test for screen reader-specific issues. Recently, we audited and fixed existing a11y-related issues in my product area at Shopify. If designers are serious about designing for inclusivity, then accessibility (a11y) shouldn’t just be a last item on their QA checklist, but a part of every design decision. An approachable guide to doing an accessibility audit using a screen readerĪccording to the World Health Organization (WHO), about 15% of the world’s population lives with some form of disability and it can be apparent or non-evident.
