Abstract: Improvements in the art of sensor and display technology now make the implementation of a workpad concept feasible. While prior art touch displays are acceptable for short, casual use tasks, they may not be feasible or suited for intensive use tasks. Recent improvements in the optical qualities (brightness, contrast, viewing cone) of flat panel displays, such as LCDs, allow implementing a touch screen for use in a horizontal orientation. This greatly improves the human factors for applications involving extensive pointing, drawing or writing.

Abstract: An advanced user interface for use with a computer system operating on an integrated operating environment. The integrated operating environment allows a plurality of application programs to be running simultaneously, one of which is designated the active application program to which all input data is directed. The advanced user interface allows a user to select among user-friendly input devices to operate any application program according to his individual preferences without change to the application program code. The advanced user interface includes alternate input modules which translate the input signals transmitted from the various input devices into input messages useable by the rest of the interface. The advanced user interface also includes interface profiles which contain mappings of the input messages against corresponding commands useable by the application programs, the integrated operating environment or other modules of the advanced user interface itself. An environment link module refers to the interface profiles and matches the input message against the corresponding command for the application program active at the time the input signal was transmitted and send the corresponding command to that application program.

Abstract: This invention describes a workpad (10) that serves as both an input and an output (I/O) device for a data processing system (60). More particularly, the invention relates to a flat display device (18) combined with a touch panel (16) and button switches (30 - 33) which provide preferably a generally horizontal viewing and work surface, the button switches being program interpretable and usable to emulate the operation of mouse buttons, function keys and the like. A single cable (56) connects workpad (10) with computer (60).
