An adaptive interaction architecture for collaborative GIS

Abstract

The research presented in this paper explores and models the interactions needed for the development of a collaborative and adaptive Geographical Information Sys-tem (GIS). The proposed framework is based on a multi-dimensional contextual ap-proach that makes the difference between the user, geographical and device contexts. The spatial distribution of the GIS functional components allows for the characteri-sation of different geographical context configurations. These configurations act as a support for the derivation of user groups. The interfaces and functionalities offered by the adaptive GIS are modeled at the group level, and derived from the interface usages and habits. The spatial behaviours that denote user experiences within a group are shared with other users within that group. Such an approach provides an adaptive and collaborative environment that favours exchanges and enrichments of the quality of services offered to the users acting in such a GIS environment. The framework is applied and experimented in the context of maritime navigation. Key words: Adaptive and mobile GIS, collaborative filtering, context-awareness 1
