Intuitive user interfaces (IUI): a CASE starting point for design and programming.

The acceptance of a software product depends to a considerable extent on the user interface. The class of graphic-oriented user interfaces that are called Intuitive User Interfaces (IUI) is described. These interfaces allow the user to learn to operate software programs quickly. In the following the graphical layout put to use in an IUI is elaborated. All images the layout consists of are created with the aid of a paint program. Using these images, a procedure for creating, programming and linking an IUI to software applications is discussed and recommendations are made concerning software and hardware demands for easily creating IUIs. Practical experience of the authors with this procedure, mainly in the medical area, is described.
