Abstract: | The first stage in the design of a user interface is the quest for its ‘typical user’, an abstract generalization of each
user of the application. However, in web systems and other scenarios where the application can be used by dozens of different
kinds of users, the identification of this ‘typical user’ is quite difficult, if not impossible. Our proposal is to avoid
the construction of interactive dialogs during the design stage, building them dynamically once the specific cognitive, perceptual
and motor requirements of the current user are known: that is, during the execution stage. This is the approach used by GADEA,
an intelligent user interface management system (UIMS) able to separate the functionality of an application from its interface
in real time. The system adapts the components of the interface depending on the information stored in a user model which
is continuously updated by a small army of data-gathering agents. |
