The direct touch interaction is considered as an important part of natural human-computer interaction and has become one of the hotspots in recent years. However, current touch interactive designs still rely on traditional WIMP paradigm seriously. To prompt and develop a dedicated user interface for direct touch interaction, in this paper, we explore the interactive features of the touch user interface through

... analysis method. We classify and summary on the components of user interface from three current mainstream mobile platforms, further abstract the components for touch operation paradigm and finally propose an interactive paradigm based on the Post-WIMP environment: PWIG (Page/Frame, Widget, Icon/Button and Gesture) paradigm. After the evaluation of PWIG paradigm, we think PWIG paradigm is more suitable for direct touch interaction and should guide the design of the natural user interface for direct touch systems.
