The project objective was to create two additional activities and to redesign the main interface for the entrance hall. Our proposition was used the principle of flashcodes for accentuating the interaction spirit between interface and participants. Each flashcode included information on the conference, the speaker... We also chosen to leave a fixed part presenting the service Agohall with a flashcode and a URL for to access at the website, the hours as well as the name. Concerning corporate identity, we have kept the same that Agoroom in order to user identify faster the service.
