Plan-based assistance in the webbrowser firefox

We present a developed function library named pbifSystem which will allow for remote control of the webbrowser Firefox. Instead of controlling the browser through general pc input devices such as mouse or keyboard, we will use functions of the library. The developed pbifSystem is meant to be a service layer that can be used by assistance systems. The service offered appears in the pbifSystem as planning an action sequence and visually executing it single-handed, which is appropriate for reaching the requested goal by the user (e.g. Increase to enlarge the font of a currently shown website). To demonstrate pbifSystem's mode of operations without assistance system, a toolbar (pbifBar) was built.
