Setting and Evaluation of Flexible Points on Software User Interface

In order to adapt to user requirement changes at runtime, software provides adaptable operations through user interfaces to change software functionality. We suggest the FleXible Point (FXP), flexible changes, flexible degree, flexible force, and flexible distance to evaluate the effect of such user interfaces. An approach and a case are given to illustrate the evaluation and setting of the FXPs. Quantitative relationship between flexible point on user interface and software flexibility is discussed and expressed. The approach can be used as a guide to adjust, improve, and to compare the FXPs on user interfaces. It is a direction for managers to arrange different levels of manipulators to increase the FXP efficiency and bring user interface flexibility into play.
