Abstract
Human-computer interaction is characterized by a vast number of frequently occurring actions. This is partly due to an increase in the amount of information being presented. A certain segment of information being presented is usually needed by only a small number of users. A small segment is usually needed by almost all users and parts of the remaining segment are of use to some users but not to all1. The average user might face the following problems in using general-purpose software (i.e., software produced for many users):
-
unneeded information is presented (information overload)
-
desired information is missing (subjective information need)
-
needed information is missing (objective information need).

References
Beside the adaptation of the amount and structure of information which is to be presented (see [Brusilovsky, 1998]) also the functionality of the software system used can be adapted. See [Linton et al., 1999] for discussion of the usage and adaptations of a general text processing software.
For instance, the use of several pseudonyms per patient which cannot be interlinked can be applied for different areas of treatment [Borking, 1998]. Further limitations for the processing of the data can be achieved through application of the least privilege and separation of duties principles (see p. 118).
To avoid the construction he/she (his/her) when concerning the user, the masculine or plural pronouns will be used.
