Supporting local mobility in healthcare by application roaming among heterogeneous devices

Abstract. This paper presents results from a research project aiming at developing an architecture supporting local mobility within hospitals. The architecture is based on fieldwork and design workshops within a large Danish hospital and it has been implemented and evaluated after a pilot phase. Our fieldwork has emphasised the differences between remote mobility, where users travel over long distances, and local mobility, where users walk around within a fixed set of buildings and/or places. Based on our field studies and our design work, we conclude that local mobility puts up three requirements for computer support; (i) it should integrate into the existing infrastructure, (ii) it should support the use of various heterogeneous devices, and (iii) it should enable seamless application roaming between these devices. The paper describes how these requirements were realized in an architecture for local mobility, and how this architecture was implemented in the healthcare domain.
