What is Wizard of Oz Testing?

Wizard of Oz Testing is a prototype evaluation method where human operators simulate the functionality of an automated system behind the scenes. This technique allows researchers to assess user interactions and gather valuable feedback without fully developing the technology.

When to use Wizard of Oz Testing?

This method is particularly useful during the early stages of user research when evaluating concepts or features that rely on automation. It helps in understanding user expectations and interactions with systems that are not yet fully operational.

When not to use Wizard of Oz Testing?

Wizard of Oz Testing may not be suitable for situations where automation is already established or when the goal is to test a fully functioning system. Additionally, it might lead to biased results if users are unaware that they are interacting with a human rather than an automated system.

What is the anatomy of Wizard of Oz Testing?

The anatomy of Wizard of Oz Testing includes clear setup requirements, such as the identification of user tasks, the simulation of automation, and the gathering of user feedback. Researchers must create an environment that closely mimics the intended automated experience while allowing for human intervention when necessary.
