Ubiquitous Computing (UC) has the potential to improve many workflows in Health Care. In hospitals clinicians move around constantly between very different work places and need to have fast access to information. Consequently, classical solutions, bound to a particular location, are often inadequate for optimal support of clinical workflows. In this paper the authors report ongoing work in R&D of UC applications in real life settings within Graz University Hospital, which is one of the largest in Europe.
