The effect of representation location on interaction in a tangible learning environment

Drawing on the 'representation' TUI framework [21], this paper reports a study that investigated the concept of 'representation location' and its effect on interaction and learning. A reacTIVision-based tangible interface was designed and developed to support children learning about the behaviour of light. Children aged eleven years worked with the environment in groups of three. Findings suggest that different representation locations lend themselves to different levels of abstraction and engender different forms and levels of activity, particularly with respect to speed of dynamics and differences in group awareness. Furthermore, the studies illustrated interaction effects according to different physical correspondence metaphors used, particularly with respect to combining familiar physical objects with digital--based table-top representation. The implications of these findings for learning are discussed

The enacted view sees technologies in the context of their use and their acceptance depending on a dynamic, unpredictable and strongly mediated process by the idiosyncrasies, needs, and preferences of individuals and groups. The view of ubiquitous commerce --or of any technology for that matter-- we choose to adopt shapes the questions we ask and our choice of research and evaluation methods. Taking the strategic view would imply that we attempt to identify the "added value" of new products and services to consumers and remove unwanted "barriers to adoption". Service evaluation would focus on the perceived value of services and ignore wider implications of the use of the system. Taking the enacted view implies the adoption of explorative research methods that would try to comprehend consumer perceptions of the impact of the new technologies in their everyday lives. In this brief, I discuss our experience in evaluating MyGrocer, a second generation ubiq
