Abstract
A method of operating a touchscreen device includes measuring a raw data value at a touch node among a plurality of touch nodes on the touchscreen device, assigning a positive touch value to each touch node having a positive raw data value greater than a first predetermined threshold, assigning a negative touch value to each touch node having a negative raw data value less than a second predetermined threshold, determining a total count of the positive touch values and negative touch values, determining a differ count for each of the touch nodes, the differ count being a number of touch nodes containing the negative touch values surrounding each touch node, calculating a percentage based on a ratio of a sum of the differ count and the total count, and entering a pre-water mode when the percentage exceeds a threshold percentage.
