Abstract : The goal of ubiquitous computing is to support implicitly the user during his everyday tasks. A ubiquitous computing application is used directly inside the physical space and depends on the geometric organization of the physical space. The services provided be a ubiquitous computing application often depend on the geographical location of the user or the relative proximity of physical objects. In this PhD thesis, we study the role of geometry in the development of ubiquitous computing applications. We propose a programming model that is based on synchronizing programs on the movements of people and physical objects. To keep the consistency between the programs' state and the physical space's state, this programming model enables us to precisely define the geometric configuration of the synchronizations. We also study the role of geometry to construct, organize and navigate through an information system. We propose a definition of context in an information system that relies on the geometric structure of the system. Afterward, we present how to use this context to navigate physically and virtually through the information system.
