From the analysis of how the Lega, a touch, motion, and location sensitive device that allows museum visitors to share their experiences, we identified kinaesthetic dialogue as an orienting concept for the understanding and the design of movement-based social interaction and experiences. It provides an analytical lens which captures critical aspects of kinaesthetic action in aesthetic experiences, as well as for better understanding of how users appropriate such artefacts in interaction. We believe that kinaesthetic dialog is a promising candidate for a meta-concept to capture interaction design knowledge in movement based technologies.
