Not all sharing is equal

Abstract

Large, shared displays are used in support of many forms of col-laborative work and are generally assumed to benefit the work. We investigate this in a qualitative study of an intervention to introduce such a display to support the work of shift handover in a medical setting. Results suggest that the consequences of introducing a shared display can be more subtle than expected. In particular, we highlight the fact that the common distinction between private and public information is too coarse-grained and discuss the importance of considering how access to public information is initiated. We briefly touch upon implications for interaction design.
