In another room, another member of the UX research team is controlling the device’s responses. Wizard of Oz can be used for virtually any interface but is particularly effective for prototyping AI-driven experiences because the range of system responses are virtually impossible to replicate with traditional prototyping tools and the cost of building a system just to test a concept is prohibitive.ĭue to the variety and complexity of AI-driven experiences, and because this topic comes up most frequently around conversational interfaces, I'm focusing this article on using the WoZ method for prototyping voice technology.Ī research session works like this: The UX Researcher is in one room with a participant who’s talking to a device that looks like a smart speaker or voice-enabled product. “Step this way, please, and I will tell you all about it.” “That was one of my tricks,” answered Oz. “How was it you appeared to me as a great head?” “But I don’t understand,” said Dorothy, in bewilderment. It's a fantastic way to explore the experience of a complex, responsive system before committing resources and development time to actually build that system. Wizard of Oz (WoZ) is a method where participants interact with a system that they believe to be autonomous, but in reality, is controlled by an unseen human operator in the next room. Since Wizard of Oz is a methodology that’s less commonly known, we wanted to dive into what it is, how it works, and why we recommend it when you’re exploring voice products. Glinda the Good Witch ( Billie Burke) instructs Dorothy to follow the yellow brick road that runs to the Emerald City, where it is said that a powerful wizard will be able to grant her wish to return home.As more clients come to us for our expertise in conversational interfaces and other AI-powered products, we’ve been recommending “Wizard of Oz sessions” more and more frequently. Though the munchkins celebrate Dorothy for her inadvertent act, the evil witch’s sister, the Wicked Witch of the West ( Margaret Hamilton), vows to kill Dorothy in order to avenge her sister and retrieve the powerful ruby slippers. Dorothy’s house lands in the midst of Oz’s Munchkinland, and she soon realizes it has fallen on and killed the Wicked Witch of the East, whose powerful ruby slippers are magically transported onto Dorothy’s own feet. When she awakens, she and her farmhouse, along with Toto, are being transported to the Land of Oz, a magical place inhabited by strange characters, including munchkins, talking trees, and witches. Before they can be reunited, however, she is knocked unconscious during a tornado. After an encounter on the road with fortune-teller Professor Marvel, a well-meaning charlatan, Dorothy is persuaded to return home to her family.
