A system and method for emulating a mouse input device with a touchpad input device having a drag switch and touch device in which the direction of movement of the touch device across the touchpad surface is determined, a display cursor is caused to move in the same relative direction as the direction determined by the touch device, and the cursor movement is continued in that same relative direction either in or out of a drag mode, even after the touch device stops moving so as to allow the cursor to be moved a greater distance than the touch device.

System and method for emulating a mouse input device with a touchpad

A method and apparatus are disclosed for determining the location of a designated point on an electrically sensitive touch-screen surface while minimizing aberrations introduced by non-uniformity in the field applied to the surface, by attaching a plurality of field-producing discrete point electrodes to widely spaced points on the surface in a predetermined geometric pattern and by measuring the currents drawn from the point electrodes upon the capacitive touching of a designated location on the surface.
