Abstract
A method for calibration of a capacitive touch digitizer system comprises detecting patterns of signals from a plurality of different events over a course of user interaction with the digitizer system, wherein the patterns of signals are outputs from a digitizer sensor of the system, determining a number of times that a pattern of signals is repeated over the different events, and defining a map of offset values as a pattern of signals that is repeated above a pre-defined repetition threshold.
