### **When Inclusive User Testing Lies: Avoiding False Insights** #### Presentation abstract Moderated user testing with people with disabilities can dramatically improve a product for everyone, unless your research setup biases your insights. “Bring your own device” testing and involving domain experts should be table stakes, but they’re only the beginning. In this talk, I’ll share lessons on how we approach inclusive, real‑world user testing at Eleven Ways. How can you avoid drawing false conclusions that may lead you to optimise the wrong things? What should you do instead? I’ll show how we apply this in our Inclusive Tech Hub in Ghent, where we use tools like eye tracking to make the invisible visible, and to design, test, and iterate with greater confidence. #### Bio Roel van Gils Roel is the founder of Eleven Ways, Belgium’s first dedicated Digital Accessibility Agency.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://netherlands.worldiaday.org/community/roel-van-gils.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
