In ubiquitous computing, both the context of use and the users' needs may change dynamically with users' mobility and with the availability of interaction resources. In such changing environment, an interactive system must be dynamically composable according to the user need and to the current context of use. This article elicits the degrees of freedom User(More)
The research presented in this paper introduces the principles of a multi-dimensional contextual approach for adaptive GIS. The framework makes the difference beetween the user, geographical and device contexts. The geographical context is modelled according to the location of the user, the region of interest, the extent of the region covered by the(More)
The research presented in this paper introduces a user context approach for collaborative and adaptive Geographical Information System (GIS). The proposed model is part of a framework based on a multi-dimensional contextual approach that combines user, geographical and device contexts. The spatial properties of the GIS components categorize different(More)
With continuous increase of available on-line spatial data, requirements for the adaptation of spatial content to user's context becomes increasingly important. Location-Based Services (LBS) deliver to the user information specific to a given location preferably using mobile devices. Personalising the information provided to the user to take into account(More)
Geographical Information Systems (GIS) have long bridged the gap between geo-information databases and applications. Although conceptual modelling approaches for GIS have been particularly successful in the representation of the specific properties of geographical information, there is still a need for a better integration of user intentions and usage.

This paper presents our work in progress in the field of emotional synthesis for psychological and physiological enrichement applied to children with mental or physical deaseases. We present a robot, MAPH, wich should be able to entertain affective relationship with children by using speech and emotional synthesis capabilities. Then we present a way to(More)
Combined research in the fields of Geographical Information Systems (GIS) and maritime systems has finally reached the point where paths should overlap and continue in better unison. This paper introduces methodological and experimental results of several marine-related GIS projects whose objectives are to develop spatial data models and computing(More)
In order to improve the interaction control and intelligibility, end-user applications are supplemented with Supportive User Interfaces (SUI), like meta-UIs, mega-UIs, helping or configuration wizards. These additional UIs support the users by providing them with information about the available functionalities, the context of use, or the performed(More)
Fuelled by the quantity of available online spatial data that continues to grow, the requirement for filtering spatial content to match mobile users' context becomes increasingly important. This paper introduces a flexible algorithm to derive users' preferences in a mobile and distributed system. Such preferences are implicitly computed from users' virtual(More)
