A method and system are provided to correct one or more sensor signals having errors induced by a viscoelastic effect. The errors may be characterized using a combination of linear or non linear functions. The characterization of the errors may be used to reduce the errors from the sensor signals. In one aspect of the invention, the errors associated with a viscoelastic effect are reduced from the sensor signals by filtering the sensor signals, scaling the output of the filter circuit to produce correction factors and subtracting the correction factors from the sensor signals. Corrected sensor signals may be used to determine the location of a touch on a touch screen with improved accuracy.
