An evaluation of mobile 3D-based interaction with complex multimedia environments

This paper describes the evaluation of an intuitive mobile environment controller. Through its 3D-based user interface, the PDA based controller provides the user with mobile access to her/his physical environment and ambient media. The goal of this usability evaluation is to test the performance and analyse the user acceptance of 3D-based interaction systems compared with traditional WIMP-based controllers. At first this paper describes the interaction model which has been evaluated. Then it explains the experiment and the approach of the evaluation. Finally we present and discuss our results.
