A novel Push-Pin icon is introduced as an intuitive graphical user interface (GUI) in associations from free layouts of printed paper sheets on a pin-up board. It is shown that necessary commands for GUI implementation can be represented by Push-Pin states. Detailed state transition diagrams for actual GUI implementation based on this icon are given. Superiority of the new GUI method to the conventional one was demonstrated in a typical application. It is firmly believed that use of the proposed method will significantly improve work efficiency of computer users.
