Abstract
A device includes a touch and pressure sensitive screen having touch pressure sensors and a controller. The controller acquires touch pressure data from the plurality of touch pressure sensors. For each touch pressure sensor, the controller determines whether the touch pressure data from that touch pressure sensor is indicative of abnormal operation of that touch pressure sensor. Where no abnormal operation is indicated, the controller sums the touch pressure data from each of the touch pressure sensors to produce a touch pressure output. Where abnormal operation is indicated, the controller sums the touch pressure data from each of the touch pressure sensors and multiply the sum by a correction factor to produce the touch pressure output.
