A novel intuitive GUI method for user-friendly operation

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 the actual GUI implementation based on this icon are given. Superiority of the new GUI method to the conventional one was demonstrated through user evaluations both in objective and subjective tests. It is firmly believed by the authors that the use of the proposed method will significantly improve work efficiency of computer users.
