When applying the Wizard of Oz (WOz) method to mobile and ubiquitous computing studies, the task of the wizard becomes more difficult as observing the user requires the wizard to be in the context. We address this problem through the ConWIZ system that allows not only to control a specific prototype but also to control parameters included in the contextual settings. In order to evaluate our approach, we setup a study with eight human wizards where we evaluated the applicability, appropriateness and usability of the ConWIZ system for mobile and UbiComp environments. Each wizard had to simulate a navigation system and control contextual parameters like simulation of wind by switching a fan on and off, and tactile feedback mechanism using the ConWIZ system. All wizards stated that the tool is definitely applicable and appropriate for supporting a mobile WOz study which allows the wizard to be hidden also if he resides in the study context. Regarding the applicability of the system, we found out that high workload may hinder the wizard from doing additional tasks such as note taking.
