User-centred design methods highlight the importance of refining the design through iterative prototyping. These methods have been used successfully when designing systems employing innovative concepts or technologies. In this paper we describe the design process of Move Grapher, a GPS-enabled, mobile learning application to support the teaching and learning of kinematic graphs in schools and colleges to children aged 15--17. Move Grapher implements a hybrid mode of interaction; besides implementing a graphical user interface, it enables learners to employ an embodied type of interaction as a way of supporting them in generating learning insights. Iterative prototyping was an important component of the design process, however, the innovative nature of the technologies employed and the embodied element of the interface had a decisive influence in determining the nature of the deployed prototypes.
