Abstract
A determination is made as to whether touch pressure data acquired from each of a plurality of touch pressure sensors is indicative of abnormal operation. If abnormal operation is indicated, the touch pressure data from each of the plurality of touch pressure sensors, except those touch pressure sensors having touch pressure data indicative of abnormal operation, is summed. Then, the sum is multiplied by a correction factor to produce a touch pressure output indicative of physical force applied to the plurality of touch pressure sensors.
