Abstract
Abstract A method of processing coordinate values of points entered in a tablet, by means of a digital data processing facility wherein a first tablet area is operated as alpha numerical keyboard by correlating discrete points entered with keyboard numbers; a second tablet area is operated as a description and encoding board by correlating discrete points entered therein with arbitrarily selected description codes; a third tablet area is operated as a graph board by storing points thereof entered in the third area in spatial relation corresponding to their spatial relation on the graph board; numbers, description codes and graph board points are correlated by means of an algorithm that operates in dependence of the order of entry of points in the first, second and third areas.
