Abstract
An exemplary method used to improve water detection on a touch-sensitive display includes performing a plurality of scans of a touch-sensitive array using at least two different scan patterns to capture response data for at least a subset of the plurality of sensor electrodes. The method further includes determining a signal direction for each sensor electrode in the subset using the response data. The method further includes identifying touch zone(s), each comprising a group of sensor electrodes with signal directions that point towards a peak electrode response included in the group. The peak electrode response indicates a location of a candidate touch object on the touch-sensitive array. For each identified touch zone, reporting a touch object at the location of the peak electrode response upon determination that the peak electrode response for the touch zone satisfies a predefined response threshold.
