ABSTRACT:
A touch terminal identifies a single user-selectable, touch-responsive pad element on the display screen for user communication with a data processing system. The terminal makes the identification in response to the durations of pulse signals which vary according to the touch-selection condition of the pad elements. A multiple-step technique of repetitively measuring the signal durations relative to reference values attains essentially error-free pad selection. The operation includes the updating of the reference values of the pulse-signal durations.
