<p>A writing pad (10) for entering information into data processor in which a grid of electrical elements defines an array of discrete locations (30) on the writing surface (12) with a density of preferably 100 x 50 = 80 locations (30) per square cm. Digital circuitry is connected to the grid to determine the locations (30) at which writing stimuli are being received. The writing surface (12) is scanned to identify the coordinate value along one dimension of a point (30) at which writing stimuli are being received. An adaptive local zone is defined in the vicinity of an identified point of touching (30), and limits the scanning to that local zone. A portion of the writing surface (12) may include key zones and a particular digital symbol is generated in response to writing stimuli being received at any of the locations corresponding to one of the key zones. <IMAGE></p> |
