Abstract
A system for determining a fold angle and an open or closed state of a foldable device includes: a plurality of electrodes, including a first set of electrodes for performing absolute capacitance sensing and a second set of electrodes for performing transcapacitance sensing, wherein each of the second set of electrodes is farther from a fold line of the foldable device than each of the first set of electrodes; and a processing system, configured to: obtain absolute capacitance measurements via the first set of electrodes; obtain at least one transcapacitance measurement via at least one receiver electrode of the second set of electrodes; determine the fold angle of the foldable device based on the absolute capacitance measurements; and determine whether the foldable device is in an open state or a closed state based on the at least one transcapacitance measurement.
