Wizard of Oz Approach for a 3DVO Video Communication System

Sara Kepplinger, Denise Tobian


This work describes the concept and the test of a Wizard of Oz Study approach. This is used in order to overcome the lack of interactivity of a pre-prototypical video communication application. The video communication system solves the problem of missing eye-contact by using free viewpoint video technology. Thereof, the quality should be evaluated. However, the system is not yet applicable in real-time due to extensive rendering. Therefore, a simulation in respect of quality evaluation is intended. The research question is towards which extent the test participants do not recognize the simulation and how this profits the design and evaluation phase. The results show the applicability of the Wizard of Oz Study approach in this context as well as critical issues on social interaction which needs to be taken into consideration and which we want to discuss within the workshop.
