Abstract
A method of generating pen data includes periodically sampling an interaction of a pen on a sensor surface in which a detected pen tip pressure is greater than zero. Pen data including detected pen positions are reported. In response to a pen up event in which the detected pen tip pressure is zero, an intended end-of-stroke position of the pen tip is predicted based on a detected pen tip position occurring at least two, three, or more samples earlier than the sample at the pen up event. The predicted intended end-of-stroke position is reported in (1) the pen data for the sample at the pen up event, in place of the actual pen tip position detected at the pen up event, or in (2) the pen data for one or more samples preceding the pen up event, in place of the actual pen tip position in the one or more samples preceding the pen up event.
