Material interactions with tangible tabletops: a pragmatist perspective

Abstract

We investigate how the interaction with tangible interactive tabletops can be seen as a material exploration of form and sound. As the theoretical foundation for our analysis we build on John Dewey's pragmatism as well as recent efforts to appropriate pragmatism for interaction design research. As the research platform for this investigation we developed an interactive tabletop, the Radar Table, which allows users to create soundscapes by manipulating tangible objects. The Radar Table was deployed 'in the wild' at a major Danish music festival, and based on video recordings we examine people's dynamic exploration of sound through the interactive tabletop. The main contribution of the paper is the development of the theoretical foundation for understanding tangible tabletops as material interfaces that can be shaped and experimented with. We build on three of the basic concepts of pragmatism: situation, inquiry, and technology, which we develop further for the study of the dynamics of material interactions with tangible tabletops as part of a research strategy of appropriating pragmatism for use in interaction design and HCI research.
