User experience evaluation with a Wizard of Oz approach: Technical and methodological considerations

摘要

User experience evaluation in human-robot interaction is most often an expensive and difficult task. To allow the evaluation of various factors and aspects of user experience, a fully functional (humanoid) robot is recommended. This work presents technical and methodological considerations on the applicability of the Wizard of Oz (WOz) approach to enable user experience evaluation in the field of Human-Robot Interaction. We briefly describe the technical aspects of the setup, the applicability of the method, and a first case study using this methodological approach to gain an early understanding of the user experience factors that are important for the development of a human-humanoid interaction scenario.
