ABSTRACT:
A data processing system is provided for emulating keyboard input. In one embodiment, the invention provides a contact sensitive graphical data input-output field for receiving graphical user input and for displaying graphical output. The graphical data input-output field includes multiple contact sensitive data input fields. The embodiment also provides a keyboard overlying the graphical data input-output field. The keyboard includes multiple keys, each of which corresponds to a data input field of the graphical data input-output field. Each key, when pressed by a user, contacts the data input field that corresponds to that key, thereby causing the data processing system to provide an electrical signal of a predetermined value that corresponds to the key pressed by the user. The keyboard further includes a window through which at least a portion of the graphical data input-output field can be viewed when the keyboard is fully overlying the graphical data input-output field, wherein the portion of said graphical data input-output field that can be viewed through the window can display graphical output.
