This paper describes preliminary results and topics from the Knowmobile project. The Knowmobile project is concerned with mobile opportunities for medical students at the University of Oslo. The focus is on the students learning context at a local hospital and at a number of general practitioners offices. The paper reports theoretical data on the multidevice paradigm. The multidevice paradigm refers to interaction with many different devices in contrast to interaction with just one device. The multidevice paradigm leads to problems connected to the use, design, harmonization, standardization and synchronization of various devices, and this paper states that introducing artefacts in a multidevice environment, must concider all these problem areas. The paper concludes that there is no one size fit all and, that the use situation for the medical students points towards the multidevice paradigm.
