Abstract

As access to large quantities of detailed spatial information becomes more commonplace through popular Web-based map browsing systems, the need for automatic spatial information filtering processes grows. Particulary in the case of wireless access, a suitable filtering mechanism can assist the user by personalising the map contents, giving priority to the most relevant content and eliding less relevant content. We have developed a generic solution for implicitly obtaining an insight into a user's interests and intentions based on their mouse interactions with a Web-based map browsing interface. Results of a previously reported experiment showed visual patterns in interface interaction across multiple users. This has led us to develop a new categorisation of the user interactions that can serve as a basis for more accurately weighting user interest profiles. This paper proposes a classification scheme for user interactions according to their functional properties by describing a `mouse movement hierarchy'. The value of such a weighting is demonstrated by employing the hierarchy to make a new experimental analysis of a dataset of previously logged user interactions. By properly understanding sequences of interactions, implicit inferences about the user's interests can be made, leading to improved map personalisation, ultimately improving the user's experience by delivering the most relevant content to the user in a timely fashion.
