- Abstract
A computer system, IconiCase, is currently being developed to assist users in the task of classifying and memorizing medical cases. The system uses assemblies of icons, called Concept Graphics (CG), as pointers to medical cases, leading to a form of electronic document delivery in which information is accessed at various levels, with a gradual transition between levels. Icons are designed to be interpreted without the help of textual explanations; however, when a new icon is introduced, its textual interpretation is automatically provided and its correspondence to the text of the case is highlighted. In the icon editor, new icons can be made by screen captures of basic shapes created with a standard painting or drawing program. It is argued that even short gaps in the way information is presented to users lead to cognitive difficulties that could be prevented by better human/machine interfaces; CG, as mnemonic devices, provide meaning that is remembered by the viewer on the basis of cues offered by the icons. In addition, the active role given to users in organizing their access to the information leads to more effective information retrieval. Problems of using iconic compositions include: difficulty in interpretation, unclear meaning for a juxtaposition of several icons, icons' excessive use of valuable screen space, and cumbersome manipulation.
