Abstract: | Most applications accessible through the Web suffer from a noticeable lack of support for adapting to the different information
needs that different users may have regarding a certain topic. However, completely automatic adaptive support can still be
confusing for users who may not understand the reasons for the dynamic change in the behaviour of an application. In this
paper, we present a possible solution to provide adaptive support that does not disorient the user. The solution integrates
a virtual January 18, assistant that is able to provide adaptive support in an adaptable application. We discuss an example
of the application of this approach involving the support of Web visits to virtual museums. We then present the results of
an empirical usability test of such an application.
