US 6,088,023 A · Integrated pointing and drawing graphics system for computers

Abstract

An integrated graphic tablet/touchpad can be toggled between an absolute (graphic tablet) input mode and a relative (touchpad) input mode. In the relative mode, a graphics window appears on an associated display only when pressure is exerted on an input surface, and a cursor can be moved by stroking the input surface. In contrast, in the absolute mode the window is always displayed, and the cursor is relocated to a new position in the window each time a stylus or finger is moved onto the input surface. A graphic tablet armrest bridge is also disclosed, as is a one-piece stick-on device that converts a portion of the area of a position sensitive cursor control input device into a cursor control area having cursor control characteristics that are different than those of the remainder of the input device.

Dependent claims

A computer program product comprising:

a computer program storage device readable by a digital processing system;
and
logic means on the program storage device and including instructions executable by the digital processing system for performing method steps for controlling a cursor on
a display associated with the digital processing system based on signals received from
a position sensitive input surface, the method steps comprising:
