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.
