Multilevel design and role play

Getting a grip on tangible interaction

“…We extend and refine this notion as referring to the interrelation of physical and digital representations and to how users perceive them. We have found that users perceive a tangible interface as "not very tangible" and the tangible objects as insignificant, if these were only of temporary relevance or not expressive [10]. Clearly the effort of producing tangible representations that take up 'interface estate' has to be justified by their relevance -either in their tangibility being a salient part of the representation (e.g.…”

“…We have found [10] that a good representation is not sufficient for supporting discussion groups if there are no lightweight means of creation and manipulation. These provide focus, allow for creating shared visions and make these discussable.…”

“…This first-hand access to use data and observations seems essential for an analysis of (social) use experience. All case studies are second-level reflections of the original studies [10,19,21,22] that helped us develop this framework. See also [20] for a deeper analysis of the cases along one theme, Embodied Facilitation.…”

“…The EDC provides an augmented game board that allows tangible interaction with projected computational simulations on an aerial photo. The first author collaborated with L3D members on evaluation and redesign of this system [10,19]. Two system versions were available for a comparative assessment (see figure 2).…”
