In this network we integrate three disciplines which are collaborating together for the first time: Conversation Analysis, Audiology, and User Centered Design. To understand human interaction and the use of technologies, Conversation Analysis rigorously examines the participants’ perspective through their actions in situ. To gain an empirical basis for technological innovation, developers in User Centered Design take as their point of departure how users actually interact with technologies and other people in the flow of their work and everyday lives. Audiologists contribute by providing access to the professional communication situations, by integrating their perspective in the analysis of interactional data, and by participating in the innovation process by identifying problems and best practices, by generating ideas for advancement and by implementing improvements in services and technologies.
