<![CDATA[Whether resulting from a voluntary act or not on the Internet, digital traces forge the invisible elements of a dynamic ecosystem (Doueihi, 2013), which recomposes and invents our society. The digital increases and rebuilds the metric space combining new types of social practices, while being tracked by different applications, software, and algorithms indexing each data. Defining space as an organized distribution of elements (Beaude, 2012) begs the question on how the link between the digital and space redefines the identity, and most importantly in which environment. Is the digital identity limited to a collection of traces of activities and movements reshuffled by the search engines (Ertzscheid, 2013)? Does this identity define beings as a person-data rather than a human-trace (Galinon-Mélénec, 2011)? How can we define the digital environment born from the new individual and collective practices, and from "mechanic" operations? In our research, we studied the different uses of the "Places" application on Facebook by a group of 30 international students in Paris, by means of a questionnaire and semi-structured interviews. The analysis of these uses shows the introduction of a space dimension in the building of the identity, in addition to the construction of a digital "urbanism" in perpetual elaboration and permanent mutation. Space as a "practiced lieu" (De Certeau, 1994) suggests that the presence produces itself with practice. Being present is the result of a process of experiments and forges itself over time. Thus, the digital environment, as well as the digital presence (Merzeau 2010) are social. They are continuously built in the invention of the everyday lives.]]>
