What is Wizard of Oz Experiment

Chapter 4
Handbook of Research on Ambient Intelligence and Smart Environments: Trends and Perspectives
A simulation-based user experiment. A subject interacts with a system that he or she believes to be autonomous, while an unseen experimenter actually operates or partially operates the system. The functionality that an experimenter performs might be implemented later, yet the complete implementation is considered irrelevant to the goal of the study.

Abstract
In this chapter, a case study on augmenting a daily object, mirror, for a contextual ambient display is presented. The mirror presents information relevant to a person who is standing and utilizing unshareable objects, e.g. a toothbrush, in front of it on the periphery of his/her field of vision. We investigated methods of interaction with the mirror by analyzing user preferences against contrastive functionalities. Experiments were conducted by a Wizard-of-Oz method and an in-situ experiment. The results showed that a short absence of the mirror function was not a big issue for the majority of participants once they were interested in presented information. The analysis also allowed us to specify requirements and further research questions in order to make an augmented mirror acceptable.
