Abstract
A conventional Nursing Information System NIS which supports the role of nurse in some areas is typically deployed as an immobile system However the traditional information system can’t response to patients’ conditions in realtime causing delays on the availability of this information With the advances of information technology mobile devices are increasingly being used to extend the human mind’s limited capacity to recall and process large numbers of relevant variables and to support information management general administration and clinical practice Unfortunately there have been few studies about the combination of a welldesigned smallscreen interface with a personal digital assistant PDA in clinical nursing Some researchers found that user interface design is an important factor in determining the usability and potential use of a mobile system Therefore this study proposed a systematic approach to the development of a mobile nursing information system MNIS based on Mobile HumanComputer Interaction MHCI for use in clinical nursing The system combines principles of smallscreen interface design with userspecified requirements In addition the iconic functions were designed with metaphor concept that will help users learn the system more quickly with less workingmemory An experiment involving learnability testing thinking aloud and a questionnaire investigation was conducted for evaluating the effect of MNIS on PDA The results show that the proposed MNIS is good on learning and higher satisfaction on symbol investigation terminology and system information
