First Claim
Patent Images
1. A method of touch control of cursor position on a display device having a touch sensitive screen comprising the steps of:
- determining from an initial contact point by a pointer on the touch sensitive screen whether a cursor is positioned at the initial contact point; and
updating the cursor position, as the pointer moves from the initial contact point in contact across the touch sensitive screen, to correspond to an instantaneous point of contact during the movement so that the cursor appears to move on the display device with the pointer.

Abstract
A method of touch control of cursor position for a display device having a touch sensitive screen determines, upon contact of the screen by a pointer, whether cursor data exists within a display memory at addresses related to the contact point. If cursor data exists, a cursor mode is initiated so that all movement of the pointer across the touch sensitive screen results in the cursor apparently moving with the pointer on the display device. Once contact is broken with the touch sensitive screen, the cursor mode is controlled conventionally with a knob.
