Abstract : The evolution of user interfaces for interactive systems, be they critical like cockpits or mainstream like personal computers, is characterized by a continuous increase of the amount of available information. Those systems support multiple activities that require the simultaneous use of numerous data and several screens, views, applications or resources. This increase of complexity raises problems to users in terms of visual perception (density, concurrency, segmentation of information) and usability (divide, interrupt, permutation of tasks). The notion of Continuity refers to a subject’s ability to “link” objects, actions or events that exhibit a proximity or similarity in space or time. This ability answers to a need of simplification and structuration of the human visual perception of the available information. The perception and identification of objects are made possible thanks to the occurrence of breaks and visual saliencies or discontinuities. Continuity and discontinuities form the consubstantial principles of an efficient and structured reading of forms and spaces, which enabled subjects to build a consistent and continuous mental image of the world and the situation. We think that the concept of continuity is a tool that is particularly well suited to answer to the evolution of interactive systems. We explore what brings this concept to HCI through tree computer science projects. First, using an approach based on experimentations, we demonstrate the significance of the continuity and discontinuity principles for the design of a typographical font adapted to critical contexts [CHI2012]. One of the outcomes of this research is the delivery to the Airbus company of 8 digital fonts for the interfaces of cockpit. With the Strip’TIC project, we emphasized the dimensions and properties of continuity for the design of a tangible interactive space for air traffic controllers. We demonstrate the scope of the concept, which enables us to reflect on the coherence of interactive systems between the physical and digital word [CHI2013]. Finally, using a design research approach, we devised two graphical principles, the limits and passages of continuity, to architecture the graphical user interface of complex interactive systems. We illustrate their use through several examples new interactive graphical techniques
