Abstract
Methods, devices and systems for controlling a fingerprint sensor system are disclosed. Some examples involve receiving a contact indication corresponding to a contact of an object with a surface of an apparatus and determining, responsive to the contact indication, multiple force values corresponding to contact of the object with the surface during a force monitoring time interval. Some examples involve determining whether at least a plurality of the multiple force values exceeds a force threshold and controlling a fingerprint sensor system based, at least in part, on whether at least the plurality of the multiple force values exceeds the force threshold.
