Abstract

A method and system are disclosed, for providing a user interface with a graphical user interface (GUI) computer system. The method comprising the steps of receiving a user input command signal, the signal including first and second signals, representative of movements of respective first and second user input mechanisms for two-dimensional movements, resolving the first and second signals from the user input command signal, operating a first displayed symbol based on the first signal, and operating a second displayed symbol based on the second signal. The invention is advantageously practiced in an environment in which the user has a plurality of two-dimensional movement input devices, such as a mouse having a joystick-type pointing device as well as the surface contact ball on its underside. A system in accordance with the invention provides the user with many advantageous features, such as the ability to scroll, in the up/down and left/right directions, the content of an image partially displayed by an application window, to move forward/backward through a sequence of frames displayed by an application window, to move a cursor over the GUI display in the up/down and left/right directions, and to move a special function sub-window, such as a magnifier, over the GUI display in the up/down and left/right directions.
