Abstract
Disclosed are systems and methods for detecting a finger touch and/or finger press. A method includes: detecting presence of a finger on a fingerprint sensor; causing the fingerprint sensor to take measurements using multiple successive frames of the fingerprint sensor; for each measurement, computing a metric associated with the measurement at a given frame corresponding to the measurement; at a first particular frame, determining that the finger has settled on the fingerprint sensor, wherein determining that the finger has settled comprises determining that the metric at the first particular frame exceeds a settled value threshold; and, based on determining that the finger has settled, determining that a finger touch has occurred. A finger press can be further determined by monitoring whether the metric passes a press threshold.
