Comment raisonner visuellement sur le paramètre temps ? Réflexions et retours d’expériences

This paper discusses how heritage architecture analysts handle time. It argues first that we are not equally equipped (in terms of concepts and formalisms) to handle space and time, in particular when dealing with historical data sets in which missing and uncertain information can be critical. It then focuses on time and on the recent contribution of visual analytics to the problems of time-oriented data and the uncertainty issue. We then propose a categorisation of the notion of uncertainty, and finally introduce and exemplify generic characteristics of time to reinforce the analyst’s capacity to perform cumulative, comparison-rich, reasoning tasks
