A method for utilizing a low resolution touch screen system in a high resolution graphics environment

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 lower 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, the zooming increasing 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 position of the stylus is calculated. A check is made to determine if the new position is within the zoomed area. If it is, the processing continues; otherwise the screen is rezoomed around the new position. When the desired character is under the pointing element, the pointing element utilized to reverse the calculation thereby identifying the position of the desired character, and thus the desired character itself.
