Abstract
A system for determining a fold angle of a foldable device, the system including a plurality of electrodes and a processing system, wherein the processing system is configured to obtain transcapacitance measurements via a subset of the plurality of electrodes; obtain absolute capacitance measurements via the subset of the plurality of electrodes; and determine the fold angle of the foldable device based on the transcapacitance measurements and the absolute capacitance measurements.
