<p>A relatively low resolution touch screen system is utilized in a graphic display environment wherein the resolution of the graphic display is relatively high. The character resolution yields a low target resolution, a single character being the target (or the desired character). The method zooms a predetermined number of characters around an initially reported position into a zoom window, the zoom window being an area of the display screen relative to the initially reported position, the center of the zoom window displaying a cursor character. The zooming increases the character resolution such that target resolution is decreased to a value resulting in a touch screen resolution at least equal to or higher than resolution of the target resolution. Further, as the stylus is moved toward the desired character, a new center position of the data to be displayed in the zoom window is calculated, the new center position following the pointer element at a predetermined speed. When the desired character is over the cursor, the pointing element iswithdrawn, the current position of the pointing element utilized to identify the position of the desired character, and thus the desired character itself.</p> |
