Although the Wizard of Oz method for simulating system components is commonly used for evaluation in human-computer interaction, researchers and designers have only started to unlock this technique's potential. This article reviews the WOz method, highlights its usefulness throughout the evolution of a user interface or system, and argues that explicitly supporting WOz prototyping in pervasive computing infrastructures will improve the method's usefulness. The authors describe a design space for WOz simulation in which the wizard takes on controller, moderator, and supervisor roles. They also describe the WOz simulation features of DART, a mixed-reality design and prototyping environment, including a lightweight method for automatically generating WOz interfaces and high-level support for visualizing evaluation results. Finally, the authors use a location-aware audio experience in Atlanta's historic Oakland Cemetery as a case study to illustrate how a wizard operator can play distinct roles throughout an iterative design process.

This article is part of a special issue on rapid prototyping.
