The Wizard of Oz technique enables users to interact with a low-cost and non-functional prototype. A "wizard" observes the interaction of users with the prototype in a back room and simulates the system responses in real time.
1. Create a low-cost and non-functional prototype for the simulation
2. Develop a test plan
3. Ask the participants to simulate the usage of the prototype
4. Assign a researcher as a "wizard" who hides in a back room, observes user interactions, and simulates system responses in real time
5. Take notes on how people perform during the interaction process
6. Conduct a feedback session with participants to understand their system experiences
