Abstract
A portable electronic communication device including a display, a pressure sensor array including a plurality of pressure sensors, and an electronic processor communicatively coupled to the pressure sensor array. The electronic processor is configured to receive, from the pressure sensor array, a plurality of stress tensor measurements corresponding to a user interaction with the display, perform an interpolation of the plurality of pressure measurements, and determine, based on the interpolation, a faulty sensor of the plurality of sensors.
