Command set for touchpad pen-input mouse

A touchpad-computer communication system to transfer digital codes between a computer system and touchpad controller, wherein said digital codes include a plurality of configuration commands that instruct said touchpad controller to assume one of a set of operating modes, a set of mouse motion digital codes, and a set of pen-input digital codes, comprising:

• a) Computer system communication adapter coupled to said computer system to transmit said plurality of input commands to the touchpad controller from said computer system, and to receive the mouse motion digital codes and the pen-input digital codes form the touchpad controller to said computer system;
• b) A communication medium to convey the digital codes between the touchpad controller and the computer system adapter;
• and
• c) The touchpad controller that will detect a presence of a pointed object upon a surface, convert said presence to a set of digital codes that indicate absolute location and force of said pointed object upon said surface,
• if a pen input mode is selected and to a speed and direction set of digital codes that conform to industry standard computer input mouse protocols,
• if a mouse mode is selected and transmit such codes through the communication medium, and
• receive the plurality of pen input commands to configure the operating parameters of said touchpad controller;
• whereby said plurality of configuration commands comprise:
• a set autocursor mode command to activate an autocursor mode, deactivate said autocursor mode, to set said autocursor mode to move the cursor only and to set said autocursor mode to move said cursor and an object upon the display screen attached to said cursor;
• a set edgezone boundary command to establish a first boundary between a workzone and an edgezone upon said touchpad;
• a set first minimum edge movement threshold command to set a value of the absolute digital codes at which the autocursor mode is be conditionally activated, wherein said set first minimum edge movement threshold command contains the value of a minimum distance between a last sampling of the absolute digital codes prior to the pointed object crossing the boundary of the edgezone and a first sampling of the absolute digital codes subsequent to crossing said boundary of the edgezone to conditionally activate the autocursor mode;
• a set second minimum edge movement threshold command to set a value of the absolute digital codes at which the autocursor mode is be unconditionally activated, wherein said set second minimum edge movement threshold command contains the value of the minimum distance from said first sampling of the absolute digital codes subsequent to crossing said boundary of the edgezone to a second sampling of the absolute digital codes subsequent to crossing said boundary of the edgezone to unconditionally activate the autocursor mode;
• a set constrained speed command to establish a constrained speed component of autocursor digital codes to move said cursor upon said display screen in a constrained motion direction;
• a set free speed command to establish a free speed component of said autocursor digital codes to move said cursor upon said display screen in a free motion direction;
• and
• a set deadzone boundary command to establish the boundary between the edgezone and the deadzone, wherein said set deadzone boundary command contains the value of the absolute coordinates for this boundary.
