Plasticité des interfaces homme-machine : concilier variabilité du contexte et stabilité de l'interface à travers le concept de perle

Abstract : With evolution of technologies, the contexts of use change dynamically throughout the interaction, in terms of user, platform and environment. This variability raises new challenges for Human Computer Interaction, with the emergence of a paradox between, on the one hand, to take advantage of this new variability and secondly, to provide stability to the user. We are taking the classic definition of context a step further by restructuring three fundamental dimensions . Thus, this new definition provides solid foundations for reasoning about variability, driven by the Time, and the stability finding his marks in the interactive Space. To address this issue, we propose a new generation of user interfaces, Pearly UI, based on the concept of Pearl. Informally, a Pearl is an overview of the context of use, and is able to show variability, i.e. its evolution over time and space, and to provide stability to the user. Formally, a Pearl is a hyper-edge of a hypergraph whose vertices are the three key entities of our model of context of use, available to complete the task of the human. Pearly UI are based on the visualization process adapted to the Pearl, allowing the representation of the context in the user interface. The concept of Pearl was designed to be general in engineering of Human-Computer Interaction, and evaluated in the context of health care.
