Development of Nursing Care Insurance Support System GUI Using Iterative Design

摘要

User interfaces for products and systems should be easy to understand and use. Because communications between users and computers are exchanged via graphical user interfaces (GUIs) for products and systems using computers, the design (the planning of communications and screen design) of GUIs has a great impact on the ease of understanding and use. Toshiba's adoption of "iterative design," in which the process of making trial products of prototypes and gathering users' evaluations is repeated in the development of GUIs until we are sure that there are no problems, gives us the capability to develop better GUIs for products and systems within a shorter period of time.In order to develop a support system for authorization of the necessity of nursing care in the wake of the introduction of the nursing care insurance system from April 2000, we first conducted task analysis, user surveys, and prototyping. We then repeated the evaluation of the responses and solutions through the iterative design process, provided suitable layouts, and developed "ALWAYS J," which is a more visually presentable and easier to use system.
