Abstract:
1. A method, comprising: receiving plural user inputs directed toward a first target located at a first position of an input panel; determining first offset data for at least some of the plural user inputs directed toward the first target, wherein the first offset data indicates a difference in at least one of distance or direction between a visual location of the first target on a display device and a hardware location on a digitizer corresponding to the visual location of the first target; receiving plural user inputs directed toward a second target located at a second position of the input panel, the plural user inputs are received without entering a dedicated or special calibration application; determining second offset data for at least some of the plural user inputs directed toward the second target, wherein the second offset data indicates a difference in at least one of distance or direction between a visual location of the second target on the display device and a hardware location on the digitizer corresponding to the visual location of the second target; determining if the first offset data differs from the second offset data by more than a threshold amount; and changing at least some calibration data associated with the second position of the input panel in at least some instances when the first offset data differs from the second offset data by more than the threshold amount.
