Abstract
A user interface can be viewed as a means of mapping user tasks to system tools. Context and adaptation are important features of a user/system interaction that can be used to simplify the task to tooi mapping and thereby improve the interface. A system based on these features would be able to adapt its actions to be appropriate for a given context. Two systems are used as examples of the use of context and adaptation. The POISE system provides assistance to the users of an office system based on models of office tasks. The adaptive document-retrieval system chooses the most effective search strategy for retrieving relevant documents in a given context. The techniques used to implement context and adaptation in these systems are considerably different, but in both systems the user interface is made more effective.
