Wizard Of Oz
The Wizard of Oz method is a role-play exercise where participants simulate a machine-human interaction to test or develop ideas. One person plays the user, while another acts as the 'wizard' controlling the machine behind a visual barrier. It's useful for exploring user behavior and interaction design.
How to run it
- 1
Set up a visual barrier between the two participants to prevent visual cues.
- 2
If testing an existing design, prepare a script outlining the machine's responses.
- 3
The user initiates a task or interaction with the 'machine.'
- 4
The 'wizard' responds based on the script or improvises in the absence of a script.
- 5
Observe and note any issues, frustrations, or unexpected opportunities that arise during the interaction.
Tips
Ensure the barrier effectively prevents visual cues to maintain the integrity of the simulation.
Encourage the user to challenge the machine to reveal potential design flaws or areas for improvement.
Observers can provide valuable insights, so involve them in the debrief.
Variations
The method can be adapted for various interaction types, not just voice control. Consider using it for testing new digital interfaces or service designs where user interaction is key.
