The traditional desktop computer have a tendency to drag users to the desk, away from their object of work. Within fields covered by the term tangible computing, researchers try to find ways to integrate computer technology in a more radical way, and minimising the desk gravitation. In this paper we argue for different interactional features that are connected to a design idea for monitoring of remote hemodialysis treatment sessions. We show how a non-traditional computer interface can come into play in a highly mobile work environment.
