![]() ![]() If your voice experience is built for another device type like a mobile phone or clock, a simple representation of that device next to the phone will suffice. The "Wizard" is using scripted replies to respond to what the participant says. Sitting nearby is a phone on ‘speaker mode’ with the “Wizard” (who’s in another room) speaking directly through the phone as if they were the voice assistant. In the room with the participant is a tennis ball canister wrapped in felt to represent a smart speaker. Low FidelityĪ low fidelity WoZ prototype might work as follows. Let’s take a look at how these work in practice. A high fidelity prototype could refine the process and scripts used to offer product reviews via email to the user.įor this reason, we typically recommend starting with low or medium fidelity prototypes and then moving to high fidelity prototypes once the idea is solidified, but before any code is committed. TL DR The higher the prototype fidelity, the more expensive it is to produce and the more likely it is to surface insights that are about its usability instead of its utility.įor example, a low fidelity prototype may reveal that participants using a voice commerce app don’t want product reviews read to them by the device, but would instead prefer to have reviews emailed to them to read through later. No actual code is involved-just a “man behind the curtain” pulling the levers like the Wizard of Oz.Īs with prototypes for apps or websites, this type of research can be done at varying levels of fidelity, and there are reasons to use each depending on where you are in your product development process and what you’re trying to test. 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. In 19th century fiction particularly, they always have to do with what they called “the woman question.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. Early on, when I was writing my thesis for Harvard in supernatural female figures in fiction, naturally I was interested in these witches. ![]() So is this turn-of-the-century insecurity about gender roles? I would say it is. Don’t you think that’s interesting? I certainly do. The Wizard has only succeeded in keeping the bad witches at bay by making people think he has magic powers. So actually none of the male characters in the book have any real magic powers. So we have three deficient male characters going to see the Wizard, hoping that they will get these things, but the Wizard turns out to be a fraud. One of them lacks courage, one of them lacks brains, and one of them lacks heart. They go with Dorothy because each of them feels he lacks something. They are the Cowardly Lion, the Tin Woodman and the Scarecrow. Let’s look at the male people in the book. They’re definitely in the book, illustrated, they look sort of like drum majorettes. ![]()
