Abstract

Users of publicly accessible information systems are generally heterogeneous and have different needs. The aim of the AVANTI project is to cater to these individual needs by adapting the user interface and the content and presentation of WWW pages to each individual user. The special needs of elderly and handicapped users are also partly considered. A model of the characteristics of user groups and individual users, a model of the usage characteristics of the system, and a domain model are exploited in the adaptation process. This paper describes the detected differing needs of AVANTI users, the kind of adaptations that are currently implemented to cater to these needs, and the system architecture that enables AVANTI to generate user-adapted web pages from distributed multimedia databases. Special attention is given to privacy and security issues which are crucial when personal information about users is at stake.
