PLUG-IN (PLan-Based User Guidance for Intelligent Navigation) is a user guidance component supporting the user of interactive applications. It generates dynamical on-line help pages and animation sequences on the fly. On the dynamical help pages textual help for the user is displayed whereas the animation sequences are used to show how the user can interact with the application. In our presentation we demonstrate the given user support by looking at the user interface of an ISDN telephone application and discuss the underlying Tcl/Tk concepts of PLUG-IN.
