This paper presents an approach to investigating interdisciplinary collaboration between an artist and a technologist based on case study methods. The aim of the research is to understand how artists and technologists communicate with each other during a collaborative process. The paper begins with a brief account of the art-technology context, and goes on to describe how the data was collected and how the analysis framework was developed specifically for this context. At the end of this paper, we discuss the preliminary findings which illustrate the characteristics of participants’ communication behaviours in art-technology collaboration.
