碩士 === 國立成功大學 === 工業設計學系 === 88 === System development includes wide fields, such as system planning, icon design, program design, usability engineering, system maintenance. This study proposes a model to developing an iconic function interface. This model could make the process of interface development standardized. It includes four phases. (1) The analysis of users’ requirement. (2) Icon design. (3) Screen design. (4) Interface and system evaluation. In the phase of the analysis of users’ requirement, the author found that patient care record system mainly includes “Admission assessment”, “Withdrawal advice”, “Vital signs”, “Care documentation” and “Care plans” subsystem. If the contents of these subsystems were admitted by nurses, the 「Patient Care Record System」 would be more organization and standardization. In the phase of icon design, some principles of Feature-Matching Theory were applied in forming the icon design process. This design process could divide into four steps: firstly, the questionnaire was used to investigate the meanings of the main functions and their constructive features. Secondly, investigating the weighting of different features. Thirdly, the existing samples of standard icons were collected and the basic features of each component among these samples were taken down. Finally, the concept design and the evaluation work were carried out according to the investigative results. In the phase of screen design, the existing principles of screen design were examined and the suitable rules were applied to arrange the screen elements of patient care record system. If screen design is suitable to the principles of standardization and consistency, the users usually have worthy evaluation. In order to obtain the benefits of survey and experimental methods, this study applied Heuristic Evaluation and Teaching Methods in the phase of interface and system evaluation. For executing the works of survey and experiment, the nurses and system developers were chosen as the subjects in this study. According to the analysis of this study, some conclusions are summarized as follows: (1) Nurses focus on the questions of nurse work, but system developers concentrate on the problems of system usability. (2) Interface and system evaluation needs two kinds of subjects - actual users (nurses) and system developers, to find out different kinds of usability problems. Finally, the author established a Patient Care Record System for nurse routine work. This Patient Care Record System could let nurses reduce the time on patient care record and pay more time on the direct patient care. When the nurses use this new Patient Care Record System, they could obtain more comprehensive data, make decision rapidly and execute nurse work correctly. This new Patient Care Record System could increase nursing service quality and nurses’ satisfaction for their patient care record work.
