Etude exploratoire des usages d'une application sociale mobile

This paper investigates issues related to the use of mobile social applications which aim at supporting coordination and communication, and enhancing the feeling of connectedness and social presence. To explore these assumptions, we conducted an empirical study of an application that enables group of users to share awareness information about their status and location. We present the results of the study, focusing on three issues: patterns of usage of awareness information, evolution of the usage, and privacy.
