A method for the detection of coordinates of the contact point for use with a touch sensitive resistor screen

摘要

A touch-point detecting method is applicable to a resistive touch panel with a touch-point detecting apparatus comprising a plurality of switches. By selectively enabling and disabling those switches, the present method comprises the steps of determining whether an external force is exerted on the touch panel, determining whether the external force is within a predetermined threshold, producing X-coordinate, and producing Y-coordinate.
