Abstract. The ability to move is an important characteristic of the human condition and an important aspect for interactive settings. The role of body movement however was not addressed with priority in human computer interaction until now. In this paper we explore the possibilities and issues for usability and user experience research utilizing body motion data. We provide an overview of relevant related work and report the setup and initial results of two studies utilizing body motion capture. We discuss the experiences made in using motion capture approaches for human computer interaction research and provide an outlook on future directions of research.
