We consider in this paper that mobile devices should be seen as active objects communicating through web technologies, in a sense that they can both receive and send information. Therefore, following our introduction motivating our work, we propose a lightweight architecture that enables object orientation through web technologies. This architecture is(More)
In the last few years, a number of spatial and spatio-temporal access control models have been developed especially in the framework of pervasive computing and location-aware applications. Yet, how useful and effective those models are in real applications is still to be proved. The goal of this panel is to discuss access control requirements in mobile(More)

There is no central authority to coordinate all operations. To coordinate their actions, organizations need to exchange information on what they are doing.(More)
Within the domain of predictive analytics [7, 11], this paper presents a mobile application for data forecasting [9] and its corresponding user interface. Although forecasting tools already exist, none of them were available on mobile devices. With a focus on simplicity, we present the results of usability surveys, based on interactions assumptions we took.(More)
