Summary
The article explores the Wizard of Oz (WOZ) method in UX research, a technique where users interact with what they believe is a fully functional system, but a human researcher is secretly operating the backend. Victor Yocco explains the fundamentals, advanced applications, and critical considerations of this method, including its growing relevance in testing agentic AI systems. The method helps uncover authentic user behavior and expectations before costly development begins, using examples like the Nintendo Power Glove's failure to illustrate the importance of understanding user interaction. The article covers when to use WOZ, how to plan studies, ethical considerations, and how the method adapts for testing AI-driven autonomous agents.
