Conferator is a social and ubiquitous conference guidance system, for enhancing social interactions at conferences based on the Ubicon software platform. Conferator aims at supporting conference participants during conference planning, attendance and their post-conference activities. The system applies active RFID proximity tags developed by the Sociopatterns collaboration. In particular, these tags allow the collection of human face-to-face proximity and the localization of participants at room level. This enables the management of online social and face-to-face contacts during the conference and to support social networking.
