Abstract
A method for providing user input on an electronic device comprising a fingerprint sensor comprising an array of sensing elements. Acquiring partial fingerprint images of a finger touching a finger touch surface of the fingerprint sensor from at least two sub-groups of sensing element. Determining a respective force value indicative of a force applied on the finger touch surface at each of the sub-groups of sensing elements when the partial fingerprints were acquired, based on the partial fingerprint images acquired from the respective sub-group of sensing elements. Determining a force value difference between a pair of the determined force values. Determining a user input based on the determined force value difference, and based on the relative location between the sub-groups of sensing elements in the pair associated with the force value difference.
