As a follow-up to the scenarios produced in our second workshop, we decided to specify the type of user interfaces that could emerge from the projects proposed by the participants. More specifically, we took each of the context they worked on and created a set of graphical user interfaces to show how the cloud computing service might appear. They are not meant to be exclusive but they illustrate the functions and possible usage discussed during the workshop. To some extent, they summarize the findings in a pragmatic way. Each of the contextual category features 2 or 3 interfaces that reflect on different types of target groups: user, system administrator, priest, sport coach, etc.
