: The Desktop metaphor has repeatedly been declared antiquated in various ways. It nevertheless continues existing. Despite the widely pronounced critique, it is still not clear what functional requirements have to be met by a new none-desktop interface. In this context, we define and explain the functional requirements (paradigms) we think fundamental for upcoming generations of non-desktop user interfaces. In close collaboration with users, we have also developed a graphical user interface (GUI) that illustrates these new paradigms and which is at the same time a concrete proposition for a new metaphor.
