Ally: Removing Bias with Wizard of Oz Screen Reader Usability Testing


Wizard of oz is a proven testing method for systems like chat, voice assistants, and IVR, but how can we adapt it for screen reader testing? In this usability method, a researcher acts as the “wizard” and responds as a screen reader would respond based on how a user chooses to navigate. This is a valuable way to receive feedback early on in the design phase, instead of waiting to conduct screen reader testing until after the web page has been fully developed. Learn about our process, trials and errors, and successes we’ve had in adapting the wizard of oz method for screen readers.
