The e-logbook is a collaborative web-based environment deployed by the Swiss Federal Institute of Technology in Lausanne (EPFL). It consists of an activity-oriented space where a community of educators, teaching assistants and students can form groups, conduct activities and perform several actions over stored and shared assets. Moreover, the e-logbook offers awareness services to sustain collaboration and coordination among the community members. This paper presents adaptive feed-oriented services designed and implemented to deliver awareness to mobile users, taking into account their device limitations and their activity context.
