The apparent resolution of a touch sensitive screen can be improved using a two-stage touch selection process, which effectively provides a "ZOOM" function for a selected area on the screen. Referring to the drawing, an initial screen (screen 1) is divided into a plurality of zones A, B, C, ..., any one of which can be selected by touching the screen with a fingertip or probe anywhere within the area of the selected zone. An "enlargement" of the selected zone would appear on screen 2. Individual zones on the "enlargement" of screen 1 could be selected.
