Abstract
A method for execution by a touch screen computing device includes obtaining a touch signal associated with a row electrode of a touch screen display that is operable to render frames of data into visible images, where the touch screen display includes rows of electrodes oriented with columns of electrodes. The method further includes spatial filtering the touch signal in a first direction of the row electrode with respect to columns of the electrodes that form intersections with the row electrode to produce first direction touch signal data. The method further includes spatial filtering the touch signal in a second direction of the row electrode with respect to the intersections to produce second direction touch signal data. The method further includes combining the first and second direction touch signal data to produce a filtered touch signal. The method further includes processing the filtered touch signal to determine touch data.
