1. A multimodal device for providing to a host computer coordinate signals representative of a position of contact in a two dimensional plane, said device comprising:
- a touch sensitive pad for providing at least one coordinate signal representing the position of contact on said pad;
logic means coupled to said pad for reading and interpreting said coordinate signal to determine the position of contact;
mode selection means coupled to said logic means for enabling user selection of one of a plurality of modes of operation of said multimodal device, said logic means processing said coordinate signal in accordance with said selected mode;
interrupt means coupled to said logic means and to said host computer for alerting said host computer that said processed coordinate signal is available for further processing by said host computer; and
wherein said plurality of modes including at least one digital mode providing for processing digital input entered into said touch sensitive pad, and further including at least one analog mode providing for processing analog input wherein said logic means continuously processes the coordinate signal corresponding to the position of contact on said touch sensitive pad and provides said coordinate signal as a change in coordinates.

Abstract
The present invention is to a touch sensitive intelligent multimodal peripheral device which includes a touch sensitive pad to which the operator applies a light pressure in a prescribed manner to effect cursor movement on a CRT screen or to input data to a computer. The device has four operating modes which are defined as the mouse mode, the absolute mode, the joystick mode and the numeric keypad mode.

15. An intelligent multimodal peripheral device for providing to a host apparatus coordinate signals representative of a position of contact in a two dimensional plane on said device, said device comprising:
-
a touch sensitive pad for providing at least one coordinate signal representing the position of contact on said pad, said coordinate signal being provided in response to said contact being made on said pad; logic means coupled to said pad for reading and interpreting said one coordinate signal to determine the position of contact; mode selection means coupled to said logic means for selecting one of a plurality of modes of operation for said peripheral device, said logic means processing said one coordinate signal in accordance with said selected mode; output means coupled to said logic means for receiving said processed coordinate signal; and interrupt means coupled to said output means and to said host apparatus for alerting said host apparatus that said output means contains said processed coordinate signal whereby said processed coordinate signal is made available for further processing by said host computer.
