The effect of a dynamic user model on a customizable mobile GIS application

Abstract

In the present paper we analyze the role that a dynamic user model may play in simplifying query formulation and solving in an existing audio-visual map interaction technique conceived for mobile devices. We have re-designed the system functionalities devoted to gain summary information about off-screen data and to suggest the best direction towards a target. We show that customizing a query on the basis of the current user profile may give the user the advantage of making queries simpler and may avoid similar steps meant to refine the results. © Springer-Verlag 2011.
