PHiP (Patient History in Pocket) is a tool designed for a mobile device that displays patient histories and permits to visually query patient data stored in the hospital database. It exploits Information Visualization techniques and it is able to accommodate on the screen a good amount of information that physicians require in their analysis of clinical cases. Two different user interfaces for PHiP have been implemented and informal user testing has been performed to compare their impact on users.
